Description

Technical Field

[0002] Die casting is a precision casting method that uses high pressure to force molten metal into a complex metal mold. In 1964, the Japan Die Casting Association defined die casting as "a method of mass production of high-precision and excellent casting surfaces in a short period of time by pressing molten alloy into a precision casting mold at high temperature." The United States calls die casting "Die Casting", the United Kingdom calls it "Pressure Die Casting", and the most familiar term to domestic general industry practitioners is Japan's term, "die casting." Castings made by die casting are called die castings. Die casting machines can be mainly divided into two different types: hot chamber die casting machines and cold chamber die casting machines.

[0003] In the prior art, the die-casting parts need to be taken out manually by tools after die-casting. However, due to the high temperature of the molded parts of the hot chamber die-casting machine, there are certain safety hazards when the operator unloads and discharges the die-casting parts. Therefore, a discharge component of the hot chamber die-casting machine is needed to solve the above problem. Utility Model Content
