Inverted buckle forming mold

Abstract

The invention discloses an inverted buckle forming mold, and relates to the technical field of injection molds. The inverted buckle forming mold comprises a bottom plate, an upper mold base, a lower mold base and a finished product. The finished product comprises an inverted buckle part, the upper surface of the bottom plate is fixedly connected with an operation box, the upper surface of the operation box is fixedly connected with the bottom face of the lower mold base, the inner wall of the bottom end of the lower mold base is slidably connected with two inverted buckle forming plates, and the opposite ends of the two inverted buckle forming plates are fixedly connected with sealing plates. According to the inverted buckle forming mold, through mutual cooperation of the structures, a secondary demolding process is achieved, the inverted buckle part of the finished product is independently subjected to demolding, the situation that in the demolding process of the finished product, the inverted buckle part is damaged, and consequently the finished product is scrapped is avoided, a lower mold plate is automatically hammered in the demolding process of a finished product body, the smooth demolding process of the finished product is convenient, and the problems that a traditional inverted buckle forming mold cannot achieve demolding conveniently, the structure is too complex, and consequently the demolding efficiency is reduced are solved.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an undercut forming mold. Background technique [0002] In the mold injection molding process, the area where the finished product interferes with the mold opening direction is called an undercut. The demoulding process of this type of finished product is usually done manually, which can easily cause damage to the undercut area and lead to the scrapping of the entire product. At present, the ejection mechanism of the injection mold generally includes the secondary ejection of the cam, the secondary ejection of the inclined ejector, and the secondary ejection of the slider, such as a mold disclosed in the Chinese patent CN201820107735.8. The setting of the inlay part can smoothly pass through the secondary ejection of the secondary ejection mechanism, and the inlay part is automatically separated from the undercut to make the product demould, which is convenient and quick,...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a mold for undercut forming, which can separate the undercut part of the finished product from the mold through the secondary demoulding process, avoiding the undercut part of the finished product being damaged during the demoulding process and causing the finished product to be scrapped , and in the process of demoulding the main body of the finished product, the lower template is automatically hammered, which facilitates the smooth demoulding process of the finished product, and solves the problems of inconvenient demoulding of traditional undercut molding molds and reduced demoulding efficiency caused by too complicated structure
