General mold manufacturing includes mold design, material selection, heat treatment, machining, debugging and installation. According to the investigation, among the factors of mold failure, the material and heat treatment used in the mold are the main factors affecting the service life.
From the perspective of total quality management, the factors that affect the service life of the mold cannot be measured as the sum of polynomials, but should be the product of multiple factors. In this way, the advantages and disadvantages of mold materials and heat treatment appear special throughout the mold manufacturing process. important.
From the analysis of the common phenomenon of mold failure, the injection mold can produce wear failure, local deformation failure and fracture failure during the service process. The important failure modes of injection molds can be divided into wear failure, local plastic deformation failure and fracture failure.
