AI Technical Summary

⚠Technical Problem

In the existing technology, injection molds cannot be effectively adjusted when over-injection occurs, resulting in a decrease in injection quality and efficiency.

⚗Method used

An injection mold system comprising a correction mechanism, an injection mechanism, and a uniform feeding mechanism was designed. Through components such as a correction groove, a buffer telescopic rod, a sealing ring, a discharge pipe, and a photoelectric switch, real-time monitoring and adjustment of over-injection are achieved to ensure uniform feeding and stable injection of the rubber material.

🎯Benefits of technology

It enables real-time monitoring of pressure within the injection cavity and timely discharge of excess material, improving the production efficiency of injection molds, avoiding material waste, and ensuring injection quality and efficiency.

Abstract

This invention belongs to the field of mold manufacturing technology, specifically an over-injection correction system and method for injection molds. The system includes a lower base plate and an upper base plate of the injection mold. A support pad is symmetrically fixed to one side of the lower base plate, and a temperature control base is fixed to one side of the support pad. A lower mold plate is mounted on the middle surface of the temperature control base, and a correction mechanism is installed inside the temperature control base. An injection mechanism is mounted on the outer surface of the lower mold plate. A material conveying cylinder is mounted on one side of the upper base plate, and a uniform feeding mechanism is installed inside the material conveying cylinder. This over-injection correction system and method for injection molds works by exposing the discharge port of the discharge pipe at the upper end of one side of the correction groove during the downward movement of the lower mold plate due to over-injection. Excess material is then discharged through the inclined discharge pipe to the connecting pipe on the outside. Furthermore, a pressure relief valve releases pressure inside the injection cavity, thus meeting the injection requirements.
