There are many ways to preheat the die-casting mould. Generally, gas injection, blowtorch, electric heater or induction heating are used in continuous production. The temperature of the die-casting mould tends to rise continuously, especially when the die-casting high melting point alloy is used, the temperature rises rapidly. In addition to the liquid metal sticking caused by the high temperature, the die-casting parts may also be deformed due to the lack of time to fully solidify, the high temperature of extrusion, and the clamping of the moving parts of the die. At the same time, too high die casting die temperature will slow the cooling of die castings, resulting in coarse grains and affecting their mechanical properties. Therefore, cooling measures should be taken when the temperature of die casting die is too high. It is usually cooled with compressed air, water or other liquids
