The author determined the parting surfaces and the gating system etc, choosed the injection molding machine, calculated the sizes of the molding parts. Side gate and hydraulic side action was used, straight pillar and puncher was used for guiding and conveying the materials. The author also choosed the materials of the mould. The structure designed in such way can ensure the reliable running of the , the author checked the match between the mould structure and the injection molding : Tee junction elbow,Plastic Injection Mould,Hydraulic components,Hydraulic components
