AI Technical Summary

Technical Problem

When the injection molding mold of existing polyamide resin products is connected to the inside of the injection pipe, the product and the feed pipe are connected to each other, affecting the product mold release treatment.

Method used

A polyamide resin product injection molding mold is designed, and the mutual overlapping communication structure between the sealing gasket and the cutting knife is adopted. When the cutting knife rotates, the sealing gasket seals the outside, and the cutting knife cuts the connection after the product is formed to improve the product demolding efficiency.

Benefits of technology

Through the design of sealing gaskets and cutting knives, the polyamide resin reflux is avoided, the product demolding efficiency is improved, and the equipment mold removal process is simplified.

Abstract

The utility model relates to the technical field of polyamide resin processing devices, and discloses a polyamide resin product injection molding mold which comprises a mold closing box, a material conveying pipeline is fixedly connected to the side face of the mold closing box, a feeding hopper is installed on the upper portion of the side face of the material conveying pipeline, a threaded pipeline is installed in the material conveying pipeline, and the threaded pipeline is fixedly connected with the mold closing box. A first mold is movably connected into the mold closing box in a sleeved mode, and a second mold is installed on the side face of the first mold. According to the injection molding mold for the polyamide resin product, the sealing gasket and the cutter are mutually sleeved and limited, meanwhile, when the threaded pipeline rotates, polyamide resin can be pushed to be conveyed between the first mold and the second mold, and after the polyamide resin is conveyed quantitatively, a sealing state is formed between the sealing gasket and the cutter; and meanwhile, the problem of backflow of the polyamide resin is avoided, and after the material is formed, the formed mold is cut by the cutter, so that the mold removal efficiency of equipment is improved.
