AI Technical Summary

⚠Technical Problem

The existing injection molding mold has an uneven cooling channel design, which leads to uneven cooling of parts, affecting the injection cycle and part quality, and is also complicated and costly to maintain.

⚗Method used

A cooling mechanism including first and second cooling components is designed. The first cooling component wraps around the molded area, and the second cooling component is located below it. Uniform cooling is achieved through a combination of irregularly shaped water pipes and condenser pipes. The modular design facilitates maintenance.

🎯Benefits of technology

This achieves uniformity in the cooling process of parts, improves part quality and production efficiency, and reduces maintenance difficulty and cost.

Abstract

This utility model discloses an injection molding die for automotive parts, including a bottom mold and an upper mold positioned directly above the bottom mold. An injection port is connected to the upper mold. The bottom mold has an internal cavity containing a cooling mechanism. This cooling mechanism includes a first cooling component placed within the cavity of the bottom mold and surrounding the molding area of ​​the bottom mold. In this utility model, the cooling channels within the injection mold are redesigned, and a cooling mechanism is added, allowing cooling water to flow evenly through all areas of the mold along a predetermined path. This ensures that the temperature of each part decreases at a consistent rate during cooling, thus avoiding various quality defects caused by uneven cooling and significantly improving the quality of the parts. Furthermore, the entire cooling channel adopts a modular design. In actual use, operators only need to operate the corresponding modules, eliminating the need for large-scale disassembly and assembly of the entire mold.
