Problems solved by technology

[0002] During the production process of the zipper puller, it is often necessary to place a part of the zipper string in the injection mold, pour the melted plastic, and after the plastic cools down, it matches the zipper string, and the zipper puller is manufactured. However, in the traditional technology, when the zipper puller is produced , it is not easy to demould, which greatly affects the work efficiency. In view of the defects in the traditional technology, it is necessary to further improve it, so that the work efficiency can be improved

Abstract

The invention discloses a zipper head injection mold with a convenient demolding function. The mold comprises a shell, a cavity is formed in the shell, and a transmission disc is arranged on the bottom end of the cavity and rotatably connected with one end of a transmission rod; a lever is rotatably connected to the other end of the transmission rod, two pull rods are rotatably connected to the two ends of the lever, and the middle of the lever is rotatably connected to the top of a supporting column; the bottom of the supporting column is fixedly connected with the shell, an injection mold body is fixedly connected to the pull rods and slidingly connected with the cavity, and a formation cavity is formed in the injection mold body; a groove is formed in the side, away from the shell, of the injection mold body. Through cooperation action of a handle, the transmission disc, the transmission rod, the lever and the pull rods, the injection mold body can move upwards and downwards duringdemolding so that a produced zipper head can be automatically demolded, the trouble of manual demolding is avoided, the influence of splashing of molten plastic on normal operation of the device is avoided, the injection mold can be detached for cleaning, and next use is not influenced.

Description

technical field [0001] The invention relates to the technical field of mold production, in particular to an injection mold for zipper sliders that is easy to demould. Background technique [0002] During the production process of the zipper puller, it is often necessary to place a part of the zipper string in the injection mold, pour the melted plastic, and after the plastic cools down, it matches the zipper string, and the zipper puller is manufactured. However, in the traditional technology, when the zipper puller is produced , It is not easy to demould, which greatly affects the work efficiency. In view of the defects in the traditional technology, it is necessary to further improve it, so that the work efficiency can be improved. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems, and propose a kind of zipper slider injection mold that is easy to demould. [0004] In order to achieve the above object, the p...
