Die casting die manufacturing is a tool for casting metal parts, and a tool for completing the die casting process on a dedicated die casting die forging machine.

The basic process of die casting is: the liquid metal is first cast at low speed or high speed into the mold cavity, the mold has an active cavity surface, and it is pressed with the cooling process of the liquid metal, which not only eliminates the shrinkage and porosity defects of the blank, but also makes the internal organization of the blank reach the broken grain in the forged state.

The use of die casting mold cooling system, in the case of the correct use of mold cooling water, not only extends the service life of the mold, but also improves the production efficiency. In actual production, we often ignore its importance, operators also try to save trouble, take over too much trouble, do not take over the cooling water pipe, some companies even in order to save costs when customizing the mold does not cooling water, resulting in very serious consequences.

Die materials are generally processed by special die steel, and no matter how good the die steel is, it has its use limits, such as temperature. In the use of the mold, if the mold temperature is too high, it is easy to make early cracks on the surface of the mold core, and some molds even do not exceed 2000 mold cracks appear in a large area.

Even in the production of the mold, because the mold temperature is too high, the mold core will change color, and even reach more than 400 degrees after measurement, such a temperature meets the mold chill state, prone to cracks, the production of products are also easy to deformation, in the case of the mold temperature overheating can greatly reduce the service life of the mold, but also reduce the use of the mold core. Thus greatly reduce the use of molds.

2. The mold must be preheated during the beginning of the production process to prevent the cold mold from suddenly encountering hot metal liquid, resulting in cracks. More complex molds can use spray lamps, liquefied gas and a good mold thermometer, and relatively simple molds can be preheated using slow pressure jets.

3. If the mold is equipped with neutron control, pay attention to prohibit the signal line connection between the die casting machine and the mold, the reason is very clear, in daily production, it is difficult to avoid the signal line with water or the joint dressing is easy to break, resulting in short connection with the machine tool.

If the signal error occurs, the alarm will automatically stop, delay the time, the signal will be disorganized, the mold will be damaged, causing unnecessary losses. Travel switch pay attention to waterproof.
