What is the fracture failure of injection mold

Fracture failure common forms are collapse edge, split, broken, burst, etc. , different injection mold, a driving force of the different fracture. Lengzuo injection mould were mainly mechanical forces. Hot-work die are in addition to the mechanical force, stress and thermal stress and organization, there are a lot of hot-work mold working temperature is higher, and adopts the forced cooling, the internal stress can be far more than mechanical stress, therefore, many hot-work die fracture is mainly related to the internal stress is too large.
fracture process of injection mold has two kinds: disposable fracture and fatigue fracture. One-off fracture for mold in stamping suddenly fracture, crack initiation, once after buckling and expand. Its main reason for serious overload or mold material embrittlement.
