| Abstract: | The structure characteristics and use requirements of an automobile rear wing were analyzed. Furthermore, an injection mould that forming the part simultaneously was designed. The designs of runner system,inner side core-pulling mechanism,cooling system,ejecting mechanism as well as exhaust system were presented. The characteristics of the mould structure included"hot runner + common runner"structure ,eleven slanted ejecting mechanisms,cooling water channel combined with water baffle,"ejector pad + slanted ejecting block + ejector pin". The practical production proves that the mould structure design is reasonable,and the running state is reliable,the quality of processed parts meets the technical requirement. |
