This topic is to beat egg machine left shell as a design model, the injection mold-related knowledge as the basis, the plastic injection mold design process.Through the correct analysis of workpiece, a pair of mould with two cavities was designed. The parting surface, gating system have been determined, the choice of injection machine, has calculated the formation spare part size. The side gate, using straight guide column, putting the material, inclined push rod and spring completed stripping and material of the mould were researched. So the structure is designed to ensure reliable mould work. Matching the mold structure and the injection machine was checked, and a set of CAXA drawing die assembly drawings and part drawings.
