The design using Pro / E software, combined with production practices to design the overall structure of the lid injection molds and the plastic parts shape, size and other aspects of the analysis to determine the process. Including the choice of the parting surface, gating system design, calculation of the molded part, side core-pulling mechanism set up, ejection mechanism and the cooling system design, in addition to the ejection force be calculated, and choose the appropriate injection molding machine. The design using Pro/E, the EMX to select the mold, screws, ejector parts, design and installation is complete, direct export 2D assembly drawings and part drawings greatly reducing the design time.
