Advanced Injection Mold Design and Monitoring System for Consistent Quality

摘要

Cooling phase in injection molding is the most important in terms of quality consistency of the molded product. Complex geometry makes it difficult to attain even cooling distribution throughout the part which leads to quality failure. Conformal cooling channels can obtain uniform temperature distribution in the mold, resulting into shorter cooling time and better quality of the product. In addition to cooling, part quality depends on the whole molding process. This paper tries to solve the problems related with quality consistency in molding process. Method of designing optimal conformal cooling channels and fabrication with 3D printing and its application in real factory is discussed. An efficient monitoring system comprised of cavity sensors is also introduced. Monitoring enables the machine user with early detection of failure and helps in control of process parameters. Combinedly, the whole work is a great contribution in terms of quality consistency and energy saving. An actual case study of automotive component is introduced to analyze and demonstrate the proposed method.
