Embodiment Construction
[0032] The present invention will be further described below in conjunction with accompanying drawing.
[0033] The invention provides a method for additive manufacturing of a copper / steel composite injection mold based on the progressive forming technology of composite plates. The manufacturing process is as follows figure 1 As shown, the high-strength bonding of the copper / steel interface in the copper / steel composite injection mold is achieved, and the profile of the copper / steel interface remains similar to the surface of the mold cavity.
[0034] The invention adopts the copper / steel composite plate whose bonding strength of the copper / steel interface is close to or exceeds that of the copper base material as the original forming material to solve the problem that the copper matrix and the steel reinforcement layer are difficult to form a high-strength interface bond in the manufacture of the copper / steel composite injection mold. The copper / steel composite plate is used ...
