Digitalization, networking, and intelligence are used as core technologies to infiltrate mold design and manufacturing. CAD/CAM/CAE technology is one of the concrete means. The injection mold is widely used in all kinds of molds. Therefore, this graduation project is aimed at the injection mold design and cavity simulation for the back cover of the detector.UG is used to complete the injection mold design and cavity simulation processing, and Moldflow is used to complete the analysis of the mold. First, The design of the detector cover injection mold is completed by UG’s mold wizard module, including the design of the parting surface, the determination of the cavity and core, the design of the gating and cooling system, the selection and addition of the mold frame, the design of the demolding mechanism and so on. Then, Moldflow was used to analyze the flow of the mold, cooling analysis, warping analysis, and achieved positive results. Finally, the UG CAM module is used to complete the roughing and fishing of NC programming, posting processing
