Requirements for the selection of materials for zinc alloy die-casting molds

(Summary description)In order to ensure that the die-casting mold meets the use requirements and meets the process performance requirements, there are different requirements according to the materials of different parts of the mold.

In order to ensure that the die-casting mold meets the use requirements and meets the process performance requirements, there are different requirements according to the materials of different parts of the mold. The specific material selection principles are as follows:
(1) Requirements for materials in contact with molten metal
The materials in contact with the molten metal have the following requirements: ① have good forgeability and cutting performance; ② have high red hardness, high temperature strength, hardness, tempering resistance and impact toughness at high temperatures; ③ have good thermal conductivity ④ It has high wear resistance and corrosion resistance; ⑤ It has good hardenability and small heat treatment deformation rate.

(2) Requirements for materials used in sliding fit parts
The materials used for sliding fitting parts have the following requirements: ① have good wear resistance and appropriate strength; ② appropriate hardenability and small heat treatment deformation rate.
(3) Material requirements for mold base and support plate
The materials used for the mold base and the support plate have the following requirements: ① have sufficient strength and rigidity; ② be easy to cut.
