Abstract

The invention discloses an injection mould capable of preventing a sliding block from failure and belongs to the field of injection moulds. The injection mould comprises a movable mold, a static mold and the sliding block and further comprises inverted hooks and a pressing board. The pressing board is fixedly connected with the sliding block, the sliding block is fixedly connected to the static mold, and the inverted hooks are fixedly connected with the movable mold. By means of the technical scheme, the phenomenon that an injection product is pulled broken due to failure of a reset spring in the sliding block can be effectively avoided, the principle is simple, and the cost is low.

Description

technical field [0001] The present invention relates to an injection mold, and more particularly, to an injection mold for preventing failure of a slider. Background technique [0002] At present, in the auto parts manufacturing industry, the slider in the mold is a common forming mechanism. Usually, the slider can reach the designated position when the mold is opened and closed through the return spring and the guide column, so as to accurately form the product structure. Among them, the stability of the guide post is relatively good, but the return spring may be fatigued or broken during long-term use, which will eventually cause the product to break when the mold is opened, and damage the slider body. [0003] After searching, the Chinese patent application number: 2015202193028, the application date: April 13, 2015, the name of the invention is: a non-briquetting injection mold bending pin slider mechanism, the application discloses a non-briquetting injection molding D...
