Description

Technical Field

[0001] The invention relates to the technical field of die-casting equipment, in particular to a test platform for injection parts of small and medium-sized die-casting machines. Background Art

[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 mold clamping part, an injection part, a hydraulic system and an electric control system. The injection part pushes the molten metal in the pressure chamber at a specified speed, and has enough energy to make it flow through the runner and the inner gate in the mold, and then fill it into the mold cavity, and then maintains a certain pressure to transfer it to the solidifying molten metal until a die-casting is formed. After the injection action is completed, the injection punch returns to its original position. At present, the test of the injection part generally needs to be carried out after the whole machine is assembled.

[0003] Moreover, before the die-casting machine leaves the factory, it is necessary to debug and test the whole machine, which involves the functions and performance of multiple core components of the die-casting machine and the key performance of the whole machine, which makes the testing time of the whole machine longer. If problems are found during the test, the installed parts need to be removed for inspection or rework.
