Based on rectangular casing for object, detailed introduces the injection mould design process. The main design using PRO/e software, according to the products part drawing for components of the three-dimensional modelling, and on the model based on the analysis of the formability, the necessary calculation and structural design. According to the rated the injection quantity and injection we can determine the mold cavity as a mold 2 cavity, the arrangement of linear symmetrical arrangement, parts with side holes, can not be directly release, so we need to design of side core pulling mechanism, lateral core pulling the slanted guide pillar drives the sliding block to complete the side hole, when more than the mainstream the material is pulled out, the rod with the agency to complete the introduction of plastic parts. Because the plastic is relatively large, so it is necessary to design the cooling system to prevent the local cooling parts, parts warpage.EMX adopted mould expert system and improve the design efficiency. Finally through the Autocad complete engineering drawing production, design of the comprehensive consideration of various factors and through the investigation to the mold for the valuation.
