AI Technical Summary

Technical Problem

In the production process of automotive clips, the number of clips is large and they are close together, making it difficult for the heat of the injection molding liquid to dissipate, which affects the cooling and molding time and results in low cooling efficiency.

Method used

The upper and lower mold cores are equipped with a first water-cooling pipe, and the heat-conducting block is equipped with a second water-cooling pipe. The cooling is achieved by using an external water-cooling system and heat dissipation through heat transfer with a heat-conducting rod, thereby improving heat dissipation efficiency.

Benefits of technology

It achieves rapid cooling and shaping, improves the cooling and molding efficiency of automotive clips, and enhances the cooling effect of injection molding liquid and heat-conducting blocks.

Abstract

This application discloses an injection mold for automotive snap fasteners that can quickly cool and solidify, belonging to the field of automotive snap fastener production technology. The key technical features include an upper mold plate and a lower mold plate, connected by a hydraulic cylinder. The bottom of the upper mold plate has multiple connecting rods, with the same upper mold core at the bottom of each connecting rod. The top of the lower mold plate has multiple fixing rods, with a lower mold core at the top of each fixing rod. The upper and lower mold cores are compatible. Both the upper and lower mold cores have a first water-cooling pipe inside, with two first water-cooling pipes symmetrically arranged. Each end of the first water-cooling pipe has a first water inlet and a first water outlet, extending to the outside of the injection mold. This application provides good cooling performance, improving the efficiency of automotive snap fastener cooling and molding.
