Abstract
This is an injection mold design to the stop plate of the car's central control box.After the correct analysis to the structure and technics characteristic of the plastic product and the performance of the ABS material,we adopt the edge gate to pour. This design introduces the designing process of the male die,female die,running system,ejection mechanism,cooling system and the choice of parting surface.It use different softwares such as CAD,PRO/E to analyze and design the three dimensional structure of the injection mold,some parts of the moldling,running system and ejection mechanism. This design includes that:the design of the plastic,the type selection and check of the injection molding machine,the definition of the parting surface,the design of the die cavity,the design of the core-pulling mechanism,the design of some parts of the molding,the runner system,the cooling system,displacement and bleed system and the design of the ejection mechanism and reset system and simple designs of other parts.The end of this design expounds the gains to the design and the conclusion to the whole designing process.
