ABSTRACT

This design is the design of injection mold parts of the square box, in combination with the traditional mechanical design after the application of the CAD/CAM technology in the design of injection mould, apply the CAD system in model and plastic injection mould design. This paper introduces the application of the current development of China's mould technology and the CAD/CAM in the mold, including AUTOCAD. Design of mechanical part, which includes the work principle and application of plastic injection mould, the design criteria. Design calculation of the plastic mold, mold structure design, selection of injection molding machine, the design of gating system, dynamic and static mold, pouring system, demoulding mechanism, ejection mechanism, cooling system design etc.. So the structure is designed to ensure reliable operation of die.
