Die-casting is a kind of pressure-casting part. It is a pressure-casting mechanical die-casting machine equipped with a casting mold. The metal such as copper, zinc, aluminum or aluminum alloy heated to a liquid state is poured into the feeding port of the die-casting machine. Die casting, casting copper, zinc, aluminum parts or aluminum alloy parts of the shape and size limited by the mold, such parts are often called die castings.

In the whole process of application of die castings, the following aspects should be paid attention to:

• When heating, the fire point at the beginning does not need to be too fast, it should be increased slowly, and it should be heated under the condition of mold clamping at the beginning; when heating, remove or block the parts on the mold that are not suitable for baking, such as guide rails Slider, spring yellow, etc.

• During the whole process of the test piece, the change of performance parameters should not be changed as much as possible, otherwise it is impossible to judge which main parameter has an impact on it.

• During the whole process of adjustment, the working pressure should be gradually increased. If the increase is too much, it will cause sticking of the mold, or the working pressure of the main parameters obtained is too high.

• When the mucous membrane appears and the casting cannot be removed, use wood or round steel to remove it. It is forbidden to tap with a special tool made of stainless steel plate, otherwise the mold will be destroyed.

• If the mucous membrane or other reasons, it is judged that it cannot be solved by itself, the abrasive tool should be removed, and the professional abrasive tool master should solve it.

• Before application, that is, before each die casting, it is necessary to remove the remaining drape and dirt on the surface of the clean abrasive tool as much as possible, otherwise the abrasive tool will be damaged, resulting in the drape of the casting, and even the flying material.

• During the whole process of application, it is necessary to moisten the position of each theme activity on time.

• Maintenance should be carried out for a certain period of time during the work of abrasive tools.

• The total flow rate of cooling water should be set according to different parts to adjust the overall temperature to be consistent.

• Regularly replace spare parts to ensure the quality of castings.

• Abrasives should be maintained and maintained on time.

How does the die casting machine operate

• Before starting the motor, first place the handle of the pressure relief valve in the pressure relief position. After the motor runs normally, release the handle of the pressure relief valve.

• Before injection, the model must be heated to the specified temperature, and then the metal solution can be pressed.

• A protective baffle should be used at the contact between the parting surface of the mold and the gate, and the operator must wear protective glasses. The operator must not stand opposite the parting surface contact point. To prevent metal liquid splashing and hurting people.

• It is forbidden to bring open flame items close to the fuel tank. When the temperature of the fuel tank exceeds the specified temperature for equipment operation, water cooling should be used.

• Tools should be used when removing castings and pouring risers from the die-casting mold. After the casting is removed, the metal debris adhering to the casting mold and the vent hole should be removed in time.

• When the work is completed, the oil pump must be stopped and all valves must be closed. If the heat preservation furnace is used to heat the molten metal, the power supply should be turned off and the ventilation equipment on the heat preservation furnace should be stopped.
