Punching and punching compound ejection die

Abstract

The invention discloses a composite push-out mould for punching a puncture. The composite push-out mould for punching the puncture comprises an upper mould and a lower mould, wherein the upper mould and the lower mould are matched with each other to form a mould body. The composite push-out mould of the punching puncture is characterized in that tool edges meshed to each other are respectively arranged on the outer peripheries of the upper mould and the lower mould; an upper mould cavity is filled with a pin absorbing layer; and in the upper mould, multiple groups of push-out mechanisms are arranged between the pin absorbing layer and the upper mould. By using the composite push-out mould for punching the puncture, the punching function, the puncturing function and the composite push-out function are integrated, the production processes are reduced, the working efficiency is improved, equipment and cost are reduced, and the structure is simple for implementing conveniently.

Description

technical field [0001] The invention relates to a mold for product production, in particular to a punching and punching composite ejection mold with reasonable structure for hard foaming products. Background technique [0002] For hard foam products that need to be trimmed and punctured, it generally needs to go through three processes. Effect of the hole on the part. [0003] In this way, not only three processes are required, but also a lot of equipment is required, resulting in the disadvantages of long production line, high labor intensity, low productivity and high production cost. [0004] In order to solve the above technical problems, some people have designed a grinding tool that integrates piercing, edge trimming and shaping, and completes the above processes at one time. However, its complex structure and unreasonable design lead to the disadvantages of low product processing efficiency. Contents of the invention [0005] The purpose of the present invention i...
