Hello landlord. There's no good answer, bother me.

The working principle of the die casting machine is as follows:
1. When the first-stage slow injection movement starts to be shot, the system excites the hydraulic oil to enter the cavity through the oil circuit integrated plate, and then enters the cavity through the channel, so as to promote the injection piston to move to the left and realize the slow injection.
2. The two-stage rapid injection movement, when the injection punch exceeds the pouring port of the barrel, the accumulator control valve is opened, and the hydraulic oil enters the cavity quickly through the mouth and mouth, and the amount of hydraulic oil in the cavity increases rapidly, and the injection speed increases.
3. The three-stage pressurized movement molten metal is filled into the cavity, when it is about to be terminated, the molten alloy begins to solidify, and then the forward resistance of the punch increases, which is controlled by the computer program, and the accumulator control valve is used to open, and it enters the cavity quickly, so as to promote the booster piston and the piston rod to move to the left.
When the piston rod and the inner and outer cone of the floating piston are engaged, they are truncated to form a closed cavity, and the pressure of the pressurized piston, the piston rod, the floating piston and the pressure of the cavity jointly make the piston obtain a pressurization effect.
4. The fast and slow time policy of slow speed, fast and pressurization can be adjusted by the control oil valve of the lead shouting oil circuit board: the power is transmitted through various hydraulic components (power components, liquid field actuators, control components, auxiliary components, working medium) and circuits, so as to achieve various actions.
Introduction to Die Casting Machine
A die casting machine is a machine used for pressure casting. There are two types: hot press chamber and cold press chamber. Later, they are divided into two types: straight and horizontal.
The die-casting machine hydraulically injects the molten metal into the mold under pressure to cool and form, and after the mold is opened, a solid metal casting can be obtained, which was originally used for die-casting leads.

1) Closing the mold;
2) pouring molten metal into the chamber by manual or other means;
3) The upper punch moves down at a low injection speed, and is quietly buried in the pressure chamber until it has just come into contact with the molten metal level;
4) The upper punch is pressed down with a higher injection velocity, while the lower punch and the upper punch maintain a relative distance of molten metal in the middle and move down synchronously;
5) When the lower punch moves down to the nozzle orifice, it just goes down to the bottom and is supported; Thus, the upper and lower punches together extrude the molten metal together and spray to the nozzle hole (a part of the sprue 6) at high speed;
6) molten metal passes through a sprue 6 that is made up of a nozzle, a gate sleeve 4, a cone hole of fixed die and a diverter 2, and is filled into the mold cavity from the inner gate 3;
7) the filling is completed, but the upper punch still maintains a certain pressure until the molten metal in the cavity is completely solidified into a die-casting 1; The molten metal in the sprue and the pressing chamber is solidified into a straight gate and a residual material cake 9 respectively;
8) Upper punch lifts and resets; At the same time, the lower punch moves upwards to cut the remaining material cake that is still connected with the straight gate;
9) The lower punch continues to rise, lift the remaining material cake out of the top surface of the pressure chamber, and then take it away manually or by other means;
10) The lower punch is moved down to reset to block the nozzle orifice;
11) Open the mold, the die-casting and the straight gate are left on the moving mold together, and then the die-casting is ejected and taken out; Once the remaining material cake is cut, the mold opening action can be executed immediately, or it can be slightly slowed down to the appropriate time, and has nothing to do with the action of lifting and resetting the lower punch;
At this point, a die-casting cycle is completed.

Summary. The adjustment method of various brands of die-casting machines is not the same, it depends on the configuration of the machine, the simple is to adjust the opening amount of the valve, and the advanced point is adjusted on the screen.
Adjusting the opening size of the valve to change the flow rate of the oil to control the speed is only to be adjusted by a simple manual way, and the other is to rely on the screen to signal the control system and then adjust the valve.
The impact of fast and pressurization on the product is to have an impact on the compactness, flash and thickness of the product.

Die casting is a metal manufacturing process in which a high-temperature metal or alloy liquid material is injected into a die casting mold, the mold is filled with pressure and speed, and the mold is cooled and solidified in the mold. In a production operation, the mold first needs to be prepared and mounted on the die casting machine. The metal or alloy block is then preheated, melted and injected into the die casting machine.
Then, through the pressure and speed of the pressure cluster in the die-casting machine, the molten metal or alloy is evenly injected into the mold, and cooled and solidified in the mold. Finally, the die casting is removed from the mold, the surface is cleaned, and subsequent treatments such as processing and painting are carried out.
In the die casting process, molds are a very important component. It is necessary to pay attention to the selection of appropriate mold materials and manufacturing processes to ensure the quality and service life of the mold. Secondly, for molten metals or alloys, the right temperature and pressure need to be controlled to ensure the effect of filling the mold.
At the same time, operators need to master good skills and experience in order to carry out stable production operations. In addition, regular equipment maintenance and maintenance are also required to ensure the normal operation of the equipment.
In general, the die-casting process is an efficient, high-precision, and highly automated metal processing method that is widely used in industries such as automotive, electronics, furniture, and construction. Through good production operation and strict quality control, we can provide high-quality die casting products for different industries to meet market demand.

How to adjust the stamping pressure of the die-casting machine! Hello, I am glad to answer for you<> the lack of pressure of the pro-die casting machine is as follows: the punching force of the die casting machine refers to the fast injection speed, not what force.
It is the beam rock of the second fast hand wheel, and it is the hand wheel on the side of the injection valve plate. But the speed has a great impact on the impact force, so the power is OK, but that is the speed regulation, if the product is thin and solidified quickly, the speed will be increased, and if the mold exhaust is not good, the speed will be slowed down (or the fast injection stroke will be shortened, is there a proximity switch, move it to facilitate the cavity exhaust. Any brand of die-casting machine will also be provided with a relief valve on the main oil circuit of the pump set, which is used to ensure that the pressure of the output port of the pump set is constant, and the pressure set by the relief valve is set by the die-casting machine at the factory, and generally does not need to be adjusted.
If no one has moved the pressure value set by the overflow source valve and the total pressure of the die-casting machine is insufficient, it may be that the hydraulic pump is worn out and the pressure cannot be raised; There is also a situation where there is a large leak point in the system, which will also make the pressure cannot be established, and it is necessary to check whether there are these two situations. Hope mine can help you <>
