Production device and method for injection molding type zipper

Abstract

The invention relates to a production device and method for an injection molding type zipper, and the production device and method are used for producing the injection molding zipper by performing injection molding on zipper teeth on a zipper belt. The production device comprises a lower mold, an upper mold arranged above the lower mold, a plurality of buffer mechanisms connected between the lower mold and the upper mold, a zipper belt conveying mechanism connected to one side wall of the lower mold, a zipper belt adjusting mechanism connected to the other side wall of the lower mold, a zipper belt limiting mechanism arranged on the buffer mechanism close to the zipper belt conveying mechanism, and a rapid cooling mechanism arranged in the lower mold, an injection molding cavity is formed in the lower mold, and the zipper belt conveying mechanism drives a zipper belt to move. According to the production device and method for the injection molding type zipper, the formed zipper teeth and zipper belt can be effectively prevented from being pulled and deformed in the subsequent treatment process, the cooling system is adopted in the zipper tooth injection molding process to improve the zipper tooth injection molding efficiency, the production efficiency is greatly improved, and the production process is stable and efficient.

Description

technical field [0001] The invention belongs to the technical field of injection-molded zipper production, and in particular relates to a production device and method for an injection-molded zipper. Background technique [0002] A zipper is a connecting piece that relies on continuously arranged chain elements to merge or separate items. It is now widely used in clothing, bags, tents, etc. [0003] The zipper is composed of chain teeth, sliders, upper and lower stops (front code and rear code) or locking pieces. Among them, the chain teeth are the key part, which directly determines the side pull strength of the zipper. Generally, the zipper has two chain belts, and each chain belt has a row of chain teeth respectively, and the two rows of chain teeth are arranged alternately. The slider clamps the chain elements on both sides, and slides with the help of the pull tab, so that the chain elements on both sides can be engaged or disengaged from each other.

Problems solved by technology

[0006] However, the current common injection molding machines mostly use natural cooling to wait for the natural cooling of the chain elements after injection molding the chain elements, or take them out for air cooling when they are half-molded. The production efficiency is low, and the latter is prone to incompleteness. Deformation caused by external factors during molding
