[0002] The die-casting machine is a device that hydraulically injects molten metal into a mold under pressure, cools it and forms it, and then prepares a solid casting after the mold is opened. Generally speaking, a die-casting machine includes main components such as a clamping part, an injection mechanism, a hydraulic system and an electric control system. The clamping part is mainly used to drive the die-casting mold to close and open. When the mold is closed, it has sufficient power to lock the mold to ensure that the mold parting surface will not expand during the injection filling process. At present, the test of the clamping part generally needs to be carried out after the whole machine is assembled.
