The Key Points For The Production And Aluminum Alloy Die-Casting Molds Use

Aluminum alloy die-casting molds have high technical requirements and high cost, which is one of the important fixed assets of enterprises. The correct use method can effectively extend the service life of the die-casting mold. In actual production, attention should be paid to three aspects: mold cooling, mold temperature control, and signal line maintenance.

Use of mold cooling system

When the mold cooling water is used correctly, it not only prolongs the service life of the mold, but also improves the production efficiency.

In actual production, we often neglect its importance. The operators also try to save trouble. If it is too troublesome to connect and connect, we don't need to connect the cooling water pipe. Some companies even do not cool down in order to save costs when customizing the mold. Water, which caused very serious consequences. The material of the mold is generally made of special mold steel through various treatments, and even the best mold steels have their limits of use, such as temperature. When the mold is in use, if the mold temperature is too high, it is easy to cause tortoise cracks on the surface of the mold core early. In some molds, tortoise cracks appear on a large scale even before more than 2000 molds. Even during the production of the mold, the color of the mold core has changed due to the high mold temperature, and even reached more than 400 degrees after measurement. This temperature is prone to cracks when the mold release agent is chilled. The produced product It is also prone to deformation, strain, and mold sticking. In the case of using mold cooling water, the use of release agent can be greatly reduced, so that the operator will not use the release agent to lower the temperature of the mold. The advantage is to effectively extend the life of the mold, save the die-casting cycle, improve the quality of the product, reduce the occurrence of mold sticking, strain and aluminum sticking, and reduce the use of mold release agents. It can also reduce the loss of ejector pins and cores caused by overheating of the mold.

The mold must be preheated during the start of production

This is mainly to prevent the occurrence of turtle cracks when a cold mold suddenly encounters hot molten metal. For more complex molds, blowtorches and liquefied gas can be used. If conditions are good, use a mold temperature controller. Simpler molds can use slow pressure. Preheating.

If the mold is equipped with neutron control, it is absolutely forbidden to connect the signal line between the die casting machine and the mold

The reason is clear. In daily production, it is difficult to avoid water on the signal line, or the place where the connector is easily broken, resulting in a short connection with the machine tool. If a signal error occurs, the alarm will automatically stop and delay the time, and the signal will be more serious. Disorder, destroy the mold. Cause unnecessary losses. Pay attention to the waterproof of the travel switch.
