Automobile backdoor die

Abstract

The invention discloses an automobile backdoor die. The automobile backdoor die comprises a product, an ejector plate, an ejector rod, an inclined guide rod, a first mold core, a second mold core and an ejection rod, wherein an open groove is formed in the lower surface of the product, an inverted buckle is arranged on the front inner wall of the open groove, a cross rib position is arranged on the top of the open groove, the ejector plate is located below the product, the first mold core is used for forming the front inner wall of the open groove and the inverted buckle, the second mold core is used for forming the back inner wall of the open groove and the cross rib position, the upper end of the inclined guide rod is abutted with the lower surface of the first mold core, the lower end of the inclined guide rod is arranged on the ejector plate, the first mold core can be driven to disengage from the inverted buckle by the inclined guide rod, the upper end of the ejector rod is abutted with the lower surface of the second mold core, the lower end of the ejector rod is arranged on the ejector plate, the upper end of the ejection rod penetrates through the second mold core and then is abutted with the product, and the lower end of the ejection rod is arranged on the ejector plate. The invention provides the automobile backdoor die, which has the advantages of difficulty in pulling the product and high reliability.

Description

Technical field [0001] The invention relates to the field of injection moulds, in particular to an automobile back door mould. Background technique [0002] With the development of science and technology, cars have gradually become a common transportation tool for people. The car back door is one of the components of the car. Generally, the car back door is made by injection molding. The two side walls of the upper end of the car back door are equipped with undercuts and cross ribs. According to the prior art, during injection molding, since the undercut and the cross rib are respectively located in the two side walls, it is easy to strain the product when the core is pulled, and the reliability is poor. Summary of the invention [0003] The technical problem to be solved by the present invention is to overcome the above-mentioned defects of the prior art, and provide an automobile back door mold that is not easy to strain the product and has high reliability. [0004] The technica...
