AI Technical Summary

Technical Problem

In the production of plastic shells of existing washing machines, the injection molding machine lacks temperature and time when melting and transporting plastic particles, resulting in incomplete melting of plastic particles and affecting molding quality.

Method used

An injection molding device including a melting material mechanism, a raw material viscosity magnitude detection feedback mechanism, a cooling and cooling mechanism and a loss compliance warning mechanism are designed. The device ensures that the raw materials are melted and injection molded separately, and automatically adjusts the injection molding pressure and speed according to the raw materials viscosity, quickly cools and cools down, and monitors the wear of the mold assembly.

Benefits of technology

High-quality injection molding of the plastic shell of the washing machine is achieved, ensuring that the raw materials are completely melted, avoiding flash defects, improving molding quality, and improving production efficiency and product accuracy through automatic adjustment and monitoring.
