Research of Fatigue Stress Cracking for Injection Mold Cavity Based on Ansys Workbench

Abstract:

The process of injection molding, packing and cooling for injection mold PET (Polyethylene terephthalate) cavity was analyzed and the cause of fatigue stress cracking was investigated. An analysis method of injection mold cavity fatigue based on Ansys Workbench(AWB)was put forward. A simulation of temperature field, displacement, thermal stress field and fatigue life for the cavity of a work cycle based on heat transfer theory was completed. Provide effective measures to avoid fatigue stress cracking and optimization design of the injection mold.
