[0002] As the lightest engineering metal material, magnesium alloy also has the advantages of high specific strength, specific rigidity, electromagnetic shielding performance, vibration absorption characteristics and thermal conductivity. It is widely used in aerospace, automobile, 3C electronics and other fields. The molding process of magnesium alloy structural parts is mainly based on die casting and semi-solid injection molding.

[0003] The magnesium alloy die casting is die-cast by a die-casting machine 5, such as Figure 6 As shown, the die casting machine is mainly composed of a clamping mechanism 51, an injection mechanism 52 and a hydraulic system 53 arranged on a die casting platform 55. The clamping mechanism 51 is used to drive the movable die 541 to close, so that the movable die 541 and the fixed die 542 form a cavity 54, and drive the movable die 541 to open, so as to take out the die casting; the injection mechanism 52 includes an injection punch 521 and a push pressure chamber 522, and the push pressure chamber 522 is connected to the cavity 54. The injection punch 521 pushes the metal in the push pressure chamber 522 into the cavity 54 under the pushing action of the hydraulic system 53, and maintains a certain pressure until the die casting is formed; the hydraulic system 53 provides power for the operation of the die casting machine 5.

[0004] In the die-casting process, the injection punch is a key component, and its operating stability and accuracy directly affect the quality and production efficiency of die-cast products.
