Why do you want to make a soft mold Generally for stamping parts or injection molded parts?

Both stamped and plastic parts can be opened with soft dies. The main feature of the soft mold is that the mold structure is designed.

The mold material and processing method are the most simplified. For example, the mold should not use the outer guide pillar, the material should use SKD11 and CR12, and the medium wire or fast wire should be used for slow wire processing, etc. In short, the mold is as cheap as possible to meet the needs of the sample, which also tests the grasp of the design.

It is mainly used in the sample trial or small batch production proofing stage before the new product is finalized, and the mold is not mass-produced. The engineering mold can also open the hard mold, and the continuous mold can also open the soft mold.

Stamping parts in the sample stage will open the soft mold, the product in the design stage at any time may have design changes, if the hard mold is directly opened, the product change will produce mold repair costs, generally in the product structure verification after there is no problem before the formal mold.

There is no difference in hardness between soft mold and hard mold, and the soft mold mainly refers to the single-step engineering mold, and the hard mold refers to the continuous mold (progressive mold). As far as I know, there is no soft mold for plastic parts.

Summary. Hello, I am glad to answer for you: the difference between molding and stamping: generally plastic molds and die-casting molds can have sliders. These two cannot be done together, the process is different, and the machines used are also different.

Difference Between Compression Forming and Stamping.

Hello, I am glad to answer for you: the difference between molding and stamping: generally plastic molds and die-casting molds can have sliders. These two cannot be done together, the process is different, and the machines used are also different.

The difference between stamping and stamping die: stamping is a forming processing party that applies external force to plates, strips, pipes, and profiles by presses and dies to produce plastic deformation or separation, and obtain workpieces (stamping parts) of the required shape and size. Compared to castings and forgings, stamped parts.

It has the characteristics of thin, uniform, light and strong. Stamping can be manufactured with stiffeners, ribs, undulations, or other methods to increase its stiffness. At present, polyurethane rubber molds, steel skin molds, sheet molds, low melting point alloy molds, zinc alloy molds and combination molds.

Ordinary presses can produce dozens of pieces per minute. The high-speed press can produce hundreds of units per minute, which is an efficient processing method, in the trial production of new products and small batch production of stamping parts, a simple stamping structure is generally adopted, which is not only simple in structure, but also convenient to manufacture, low in cost, and can meet certain processing quality requirements.

Soft molds are relative to BAI

The concept of a hard tool. DU in the part design process.

In general, it is necessary to verify whether the design of the plastic part is reasonable and whether it can meet the requirements of the assembly and product, and it may be necessary to make design changes constantly. In this way, it is necessary to open a sample mold before mass production, and one hole is out for easy modification. Until the design is no longer changed and mass production begins, the production capacity of one cavity is limited, and it is necessary to open a multi-cavity hard mold.

In the comparison of soft mold and hard mold, soft mold is basically the same except that the choice of steel is not as good as that of hard mold (that is, mold life).

I don't understand what you mean by rapid prototyping, is it carved with plastic samples? If this is the case, then the rapid prototyping part does not need a mold, but only a few or dozens of samples can be made, which is very costly. The general life of the soft mold is not less than 50,000 molds, or even higher.

If the batch of plastic parts is not large, it is often possible to fully meet the production capacity with a soft mold for one hole. FYI.

The soft mold is copied from pre-hardened steel, and the production cycle is shorter, mainly to verify the structure of the DU product, and the injection molding process can be done

The difference is: rapid prototyping is to melt the plastic from the injection machine and enter the mold under the action of plunger or screw thrust, while injection molding is to inject high pressure into the mold cavity.

Injection molding: Injection molding, also known as injection molding, is a molding method that is both injection and molding. The advantages of the injection molding method are that the production speed is fast, the efficiency is high, the operation can be automated, the variety of colors and colors, the shape can be from simple to complex, the size can be from large to small, and the size of the product is accurate, the product is easy to be replaced, and the shape of the complex part can be formed, injection molding is suitable for mass production and complex shape of products and other molding processing fields.

A method in which a completely molten plastic material is stirred by a screw at a certain temperature, and then cooled and solidified to obtain a molded product. This method is suitable for mass production of parts with complex shapes, and is one of the important processing methods.

Rapid prototyping: It is the process of melting plastic from an injection machine into a mold under the action of a plunger or screw thrust and cooling to obtain a product. A plastic processing method in which the plastic is plasticized in the heated barrel of the injection molding machine and then injected into the mold cavity of the closed mold by a plunger or reciprocating screw. This method can process products with complex shapes, precise dimensions or inserts, and has high production efficiency.

Most thermoplastics and some thermosets such as phenolic plastics can be processed in this way. The material used for injection molding must have good flow in order to fill the mold cavity to obtain the product.

Soft mold manufacturing is generally obtained through the mold reproduction process, and the special rubber for the process mold is made by curing and molding. Genus.

The required master is a hard tool.

Silicone rubber soft mold.

soap, soft molds, etc.

Although soft molds have some advantages that hard molds can't match. But the elasticity of the soft mold also leads to the problem that the mold in the imprinting process is easy to deform, and this deformation may lead to the failure of pattern transfer on the one hand; On the other hand, it restricts the accuracy of the product.

Rapid prototyping (RP) technology is an advanced manufacturing technology developed in the nineties, and is a key common technology for the development of new products for manufacturing enterprises, which has a positive role in promoting product innovation, shortening the new product development cycle and improving product competitiveness.

It can directly accept product design (CAD) data without the need to prepare any molds, tools and fixtures, and quickly manufacture prototypes, molds or models of new products.

Figuratively speaking: a rapid prototyping system is the equivalent of a machine"Stereoscopic printers"

It's a soft mold!! The rubber mold correction tool is used for self-soft mold forming, which is simple to manufacture and low cost, and the surface of the workpiece is not easy to be scratched, but the pressure loss is large, and the rounded part of the workpiece is difficult to form, which is not suitable for the workpiece with complex shape and large depth. Hydroforming eliminates these shortcomings, but when the liquid acts directly on the workpiece, it is critical to address the sealing problem.

Hydraulic-rubber soft mold forming can overcome the defects of the above two kinds of soft mold forming and form workpieces with various complex shapes. When using a rigid die to draw a deep curved surface shape part, there is a free surface area that is not in contact with the punch on the bad material, and the stress state is one pull and one press, which is easy to wrinkle; The stress state of the soft mold is two-way tensile stress, which fundamentally eliminates the factor of wrinkle induction. There are two types of soft die forming: soft punch and soft die.

Soft punches are used to form large flat surfaces and small depths, and the main disadvantage is that the middle part of the blank is easy to thin. When using a liquid punch, because there is no friction between the liquid and the blank, the stability of the blank is not good and it is easy to deviate. The soft die can be used to form the workpiece with complex shape and large depth, due to the action of high pressure, the blank is tightly wrapped in the punch, not only the blank positioning is accurate, but also has the effect of auxiliary forming, and expands the possibility of one-time forming of the part; In addition, the mold is versatile and simple in structure.

Stamping is a pressure processing method that uses a die mounted on a press to apply pressure to the material at room temperature to produce separation or plastic deformation, so as to obtain the required parts.

Stamping die is an indispensable process equipment for stamping production and is a technology-intensive product. The quality, production efficiency and production cost of stamping parts are directly related to the design and manufacture of molds. The level of mold design and manufacturing technology is one of the important indicators to measure the level of product manufacturing in a country, which determines the quality, efficiency and development ability of new products to a large extent.

1.Injection molds, also known as injection molding, are a method of producing thermoplastics. It can also be used for the molding of thermosetting plastic products, and its structure is generally more complex. High cost.

2.Extrusion mold is also called extrusion molding. It is the most versatile and large processing method in thermoplastic molding.

He is mainly used for the production of continuous profiles such as: pipes, rods, wires, plates. Bo film.

Coating and coated products of wires and cables, etc3.Blow Molding Mold:

The plastic is first extruded into a tube base by extrusion. The tube is then continuously expanded to a certain size with the help of compressed air blown into the tube. After cooling, it is a kind of Bo film production method that closes into a certain width of pipe membrane.

1. The composition of the mold is different.

Pressure injection mold: fixed mold, fixed on the fixed mold mounting plate of the die-casting machine, with a sprue connected with the nozzle or pressure chamber; The moving mold is fixed on the die-casting motorized mold mounting plate, and when the mold is moved and clamped with the moving mold mounting plate for opening and closing, the cavity and the casting system are closed, and the liquid metal fills the cavity under high pressure; When the mold is opened, the moving mold is separated from the fixed mold, and the casting is pushed out with the help of the push-out mechanism located on the moving mold.

Injection mold: The moving mold is installed on the moving template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. During injection molding, the moving mold and the fixed mold are closed to form a gating system and cavity, and the moving mold and the fixed mold are separated during the mold opening so that the plastic products can be removed.

In order to reduce the heavy mold design and manufacturing workload, most of the injection molds use standard mold bases.

2. The elements of the mold are different.

Injection mold: Die casting mold is one of the three major elements of die casting production, and the correct and reasonable structure of the mold is a prerequisite for the smooth progress of die casting production, and plays an important role in ensuring the quality of castings (pass rate).

Injection molding: Controlling the temperature of the fluid is the most common method, and the control accuracy can meet the requirements of most situations. With this control method, the temperature displayed on the controller and the mold temperature are not consistent; The temperature fluctuations of the mold are quite large because the thermal factors that affect the mold are not directly measured and compensated for these factors, including changes in the injection cycle, injection speed, melting temperature and room temperature.

3. The disadvantages are different.

Pressure injection mold: Although the finish of the fixed mold cavity is very smooth, due to the deep cavity, it still sticks to the fixed mold.

Injection mold: The temperature in the injection mold is uneven at each point.

1. The structure of the die-casting mold and the injection mold are very similar, and the concept is also very similar. The main difference between the two is that the product after die casting mold is metal, and the product after injection molding is plastic. Of course, there will be differences in the specific process.

2. Die-casting mold refers to the precision casting method of filling molten gold into the cavity under high pressure and high speed conditions, and cooling and solidifying under high pressure.

3. Injection mold refers to the mold in which the molten resin material is injected into the metal model under high temperature and high pressure, and the plastic product with a certain shape is obtained after cooling.

The biggest difference between plastic molding pressure injection molds and compression molds is that the former has a separate charging room.

Pressure injection mold: under high pressure and high speed conditions, the molten metal is filled under the mold, and cooled and solidified under high pressure to form a precision casting method.

Compression mold: A mold used to melt and solidify plastic placed directly into the cavity with the help of pressure and heat.

Generally, there are injection molds, blow molds, die-casting molds, sheet metal molds, progressive molds, several common molds, what you say about plastic molding is injection molding, the product is produced by plastic parts, and the general raw materials are zinc and magnesium, and the production is metal parts.

Sheet metal molds are also made of plates as raw materials, and they also belong to hardware molds.

The blow molding mold is generally a plastic as the raw material, and the product is mainly a preform.

The soft mold is made of pre-hardened steel, and the production cycle is short, mainly because Wang Sanzao can quickly proofing in order to verify the product structure and the possibility of injection molding process, and after the verification is completed, it can be produced in small batches.

Difference: Rapid prototyping is to inject molten plastic from an injection machine into the mold under the action of a plunger or screw thrust, while injection molding is to inject high pressure into the mold cavity.
