Mold temperature machine, also known as mold temperature control machine, is widely used in plastic molding, light guide plate. Die-casting, extrusion. Extrusion, rubber tires.

Roller. Chemical industry. Reactor.

Gluing. refining and other industries. Broadly speaking, it should be called a temperature control device, which includes temperature control in both heating and freezing.

The application of mold temperature machine in the plastic industry is relatively common, and its main functions are: 1. Improve the molding efficiency of products; 2. Reduce the production of defective products; 3. Improve the appearance of the product and inhibit the defects of the product; 4. Speed up the production progress, reduce energy consumption and save energy. There is also a lot of room for the application of mold temperature machine in the die-casting industry, especially in the manufacture of magnesium alloy and aluminum alloy, uneven or inappropriate mold temperature will lead to unstable size of castings, deformation of ejection castings in the production process, thermal pressure, mold sticking, etc

The high-gloss mold temperature machine is a kind of equipment used in plastic injection molding processing, which works by controlling the temperature of the mold through heating and cooling to achieve the effect of optimizing injection molding.

Specifically, the high-gloss mold temperature machine controls the temperature of the mold through a heating and cooling system.

During the injection molding process, the mold needs to be kept at a certain temperature to ensure that the plastic material can flow sufficiently and form the desired shape.

Therefore, according to the requirements of the injection molding process, the high-gloss mold temperature machine heats the mold to the desired temperature through the heating system, and then cools the mold to the appropriate temperature through the cooling system to facilitate the molding and release of plastic materials.

In addition, the high-gloss mold temperature machine can also achieve precise control of the mold temperature by controlling the temperature and time of the heating and cooling system to meet the requirements of different injection molding processes.

At the same time, the high-gloss mold temperature machine can also realize automatic control by monitoring the mold temperature and parameters in the injection molding process, and improve production efficiency and product quality.

Taking the high-gloss mold temperature machine of Ollante as an example, the first thing is to increase the mold temperature to a set value (generally between 130 degrees and 150 degrees), and then start to inject plastic into the mold cavity, after the injection molding machine completes the pressure holding and turns to cooling, it begins to inject cold water, the mold temperature quickly drops to a set value and then opens the mold, and then blows air into the mold to blow the cold water away completely to complete the entire injection molding process. This is how the high-gloss mold temperature machine works.

The working principle of the high-temperature mold temperature machine is simply an internal circulating heating process, the mold temperature machine and the heated equipment form a closed pipeline, the use of electric heater heating, circulating pump conduction medium, and combined with the intelligent control system to realize the fluid temperature control device in the circulation system, to provide high and low temperature circulating medium temperature control for the equipment that needs to be cooled or heated. Carbon steel integrated forming pipeline is used to reduce pipe resistance and fouling, and through the upgrading and improvement of circulating pumps, management elements, heating pipes and other components, it is more pressure-resistant and high-temperature resistant to ensure the safety of work. The emergence of high-temperature mold temperature machine solves the temperature limitation of ordinary mold temperature machine and expands the application field of mold temperature machine.

Some high temperature requirements have to use high-temperature mold temperature machines, such as chemical reactors.

High-temperature mold temperature machines are divided into two categories: high-temperature water temperature machines and high-temperature oil temperature machines.

1.High temperature water type mold temperature machine.

The high-temperature water mold temperature machine is a kind of high-temperature mold temperature machine, its heat conduction medium is water, and the temperature control range is 180 at room temperature. Higher temperatures are achieved by pressurization.

When the high-temperature water mold temperature machine is just started, the water source is introduced by the cooling circulation pipe, and automatically starts to exhaust, after the water in the whole system is replenished, the pressure detection system automatically measures the water supply pressure, and the temperature value can be set after reaching the requirements, at this time, the heating device starts to work, the temperature is detected by the disorderly temperature probe, and the setting value is not reached, the heating device has been working, when the temperature reaches the set value, the temperature sensing probe feeds back the signal to the computer board, and the computer board outputs the signal to stop heating; If the temperature exceeds the set value, the cooling solenoid valve will be activated, and some cold water will be introduced to cool the fool until the set temperature is closed.

2.High temperature oil mold temperature machine.

The high-temperature oil temperature machine uses heat conduction oil as the heat transfer medium, which has the characteristics of "low pressure and high temperature", and the temperature can reach 300-400 through technical improvement.

The high-temperature oil temperature machine uses electric energy as the heat source, and the temperature can reach 300 -400, that is, the heat is generated by the tubular electric heating element immersed in the heat transfer oil, and the heat transfer oil is used as the heat carrier, and the heat is transmitted to one or several heating equipment through the trembling superheated oil circulation pump. When unloaded by the heating equipment, the heat conduction oil passes through the circulating pump again, returns to the electric heating oil furnace and then absorbs the heat and transmits it to the heating equipment, so that the heat is continuously transferred. Ensure that the thermal equipment can be used to obtain a continuous and stable high-temperature energy source.

The working temperature of the high-temperature mold temperature machine is generally 300 350, which is widely used in many industries, because the high-temperature mold temperature machine has a cooling device - heat exchanger, which can indirectly circulate and cool the heat transfer oil, and the application of the high-temperature mold temperature machine in the suppression industry is here.

In the die-casting process, the alloy solution enters the cavity of the mold comic under pressure, and the heat will solidify, so that die-casting is obtained. If the heat loss is too fast, cold streaks will appear on the die casting, and the heat generation will be slower, which will increase the die casting molding time and reduce the productivity. Inappropriate mold temperature will lead to defects such as poor size of die casting, deformation, mold molding, surface depression, etc., so mold temperature control plays an important role in die casting production.

The function of the mold temperature machine is to heat or cool the mold and maintain its working temperature. For example, in the plastic industry, the main function of the mold temperature machine is to improve the molding efficiency of plastic products, and the mold temperature machine can accurately control the temperature in the production process of plastic products, which can help plastic products to form quickly, so as to improve the molding efficiency of plastic products. In the plastic industry, temperature control plays an important role in the process of product shaping, good temperature control and accuracy can help us better grasp the production of products and product shaping, and avoid the production of inferior products.

The mold temperature machine is mainly used as a temperature control mechanical equipment in the production of orange and blue failure, and the requirements and functions of the mold temperature machine in different industries are not necessarily the same, but in general, the mold temperature and smart file machine is a weapon to help you make money and save money!

Mold temperature control machine, also known as mold temperature control machine, is widely used in plastic molding, light guide plate die-casting, rubber tires, rollers, chemical reactors, bonding, mixing and other industries. Broadly speaking, it is called temperature control equipment, which includes temperature control in both heating and freezing.

The application of mold temperature machine in the plastic industry is more common, and the main role is:

1. Improve the molding efficiency of the product;

2. Reduce the production of defective products;

3. Improve the appearance of the product and inhibit the defects of the product;

4. Speed up the production progress, reduce energy consumption, and save the source of skill.

There is also a lot of room for the application of mold temperature machine in the die-casting industry, especially in the manufacture of magnesium alloy and aluminum alloy, uneven or inappropriate mold temperature will lead to unstable size of the casting, and the deformation of the casting will be ejected during the production process, resulting in defects such as thermal pressure, sticking mold, surface depression, internal shrinkage porosity and hot bubbles. There is also an impact on the production cycle, such as unstable variables in filling time, cooling time and spraying time. The life of the mold can also be affected by the impact of overcooling and overheating, which can cause hot cracking of expensive steel, accelerating its aging.

In a modern factory, in response to market competition, save manpower, improve quality, reduce the cost of the business strategy is urgent, the use of mold temperature machine, can reduce the mold preheating time, improve the surface quality of the finished product and can be fully automated production. Increasing mold life is a necessity to increase productivity.

The use of temperature control machine in other industries is an inevitable condition for the composition of equipment, and the name is different. In the PVC sheet roller temperature control, it is called the oil heater, in the extruder equipment, it is called the temperature control device, and in the rubber mixer equipment, it is called the temperature control system or temperature controller. After the temperature in the rubber plant is heated, a cooling process is also carried out for a long time.

The working principle of the mold temperature machine is very simple, that is, the pump drives the heat transfer medium (water or heat transfer oil) from the water tank with the built-in heater and cooler to the heating equipment, and then from the heating equipment back to the water tank. The controller controls the internal temperature of the mold according to the temperature of the hot fluid measured by the temperature sensor, and adjusts the temperature of the hot fluid to adjust the temperature of the equipment with hot eggplant.

The mold temperature machine is mainly used for wide luggage

1. Improve the molding efficiency of the product;

2. Reduce the occurrence of defective products;

3. Improve the appearance of the product and inhibit the defects of the product;

4. Speed up the production progress, reduce energy consumption and save energy.

The mold temperature machine is mainly composed of heating module, power module and other modules; When the mold temperature machine is started, the Sakura mold power module uses a pump to transport water (or heat transfer oil) to the pipe and mold, and transmits the fluid temperature and pressure to the control system through the sensor, so that the PLC program can adjust the temperature, pressure, flow rate and so on of the whole machine, so that the temperature of the mold meets the needs of product production.

The main purpose of the mold temperature machine is to adjust the temperature of the fluid in the circulating system, so that the working temperature is constant at the set value to ensure that the mold temperature is normal.

The working principle of the mold temperature machine is well understood, that is, the pump drives the heat transfer medium (usually water or oil) from the system equipped with built-in heaters and coolers to the heating equipment, and then from the heating equipment back to the system. The temperature controller controls the internal temperature of the mold according to the temperature of the thermal fluid measured by the temperature sensor, and adjusts the temperature of the thermal fluid to adjust the temperature of the heating equipment.

Taking the oil temperature machine as an example, the oil mold temperature machine uses heat conduction oil as the heat transfer medium, heats up with electric heat, and operates in a closed-circuit circulation system under low pressure and high temperature to directly release heat, so as to achieve the purpose of providing heat transfer. After the heat energy is transported to the heating equipment, the forced liquid phase circulation method is used to heat the heat transfer cycle heat transfer cycle heating heat transfer to achieve heat transfer.

The staff who are familiar with the mold temperature machine know that the mold temperature machine is generally divided into two types: water mold temperature machine and oil mold temperature machine. It is a device that provides a constant temperature heat source for machinery and equipment, and has the function of heating and cooling. It is widely used in Mengyou plastic molding, light guide plate, die-casting, extrusion, rubber tires, rollers, chemical industry, reactor, bonding, mixing and other industries.

There are two cooling methods of the mold temperature machine, direct cooling and indirect cooling. When the temperature exceeds the set temperature or the pressure reaches the upper limit, the drain solenoid valve automatically opens to drain away part of the hot water, and the inlet solenoid valve is opened, and the tap water with lower temperature is supplemented by the lower temperature for cooling and depressurization. The direct cooling system is widely used because of its simple design, obvious cooling effect, and low manufacturing cost compared to indirect system.

Indirect cooling methodThe indirect cooling method uses the cooling circuit to separate the cooling circuit from the main circuit, and dissipates the heat through heat exchange, and is applied to the high-temperature water temperature machine or oil temperature machine. Because the temperature is usually used above 160, the internal main line is circulated with high temperature steam, and the internal pipeline pressure is relatively large, if the direct cooling method is used, the external water pressure is greater than the internal main line water pressure to enter the main line for cooling. This method is easy to be disabled, so the high-temperature water-type mold temperature machine also uses indirect cooling.

Because water and oil cannot be mixed together during the heating process, the oil conveying mold temperature machine adopts indirect cooling, and its method is usually cooled by plate exchanger.

The working principle of the mold temperature machine is that the mold temperature machine pipeline is connected with the oil channel of the god mold to form a loop, and the heat conduction oil is circulated under the action of the pump. The temperature sensor transmits the data to the control system, which automatically adjusts the heating and cooling action and controls the temperature of the heat transfer oil.

The mold temperature machine is used to adjust the balance of the temperature, which can be heated or cooled. The mold temperature controller uses high heat transfer to conduct heat** in order to dissipate excess heat from the heating equipment in a very short time.

When the mold temperature machine is working, after setting the thermal equilibrium temperature, the temperature can be automatically controlled within a small error, and the constant value can be maintained. After setting the thermal equilibrium temperature, the temperature can be automatically controlled within a small error and the fixed value can be maintained.

The working principle of the mold temperature machine can be simply understood as the heat exchange between materials, which is equivalent to the heat exchanger, but the object of heat exchange is different, the oil heater uses the heat transfer oil as the heat transfer medium, heats the heat transfer oil through the heating wire, uses the circulating pump to transport the high temperature heat transfer oil to the heating object, controls the temperature of the heating object by controlling the temperature of the heat transfer oil, the function of the heating tube is to heat the heat transfer oil, and the role of the cooling cylinder is to cool down when the temperature of the heat transfer oil is higher than the set temperature.
