Inject mold Design of Automotive switch
Abstract: The graduation project topic focuses on automotive switching injection molding process and design, which are the main parts of the car kit, plastic injection molding, high surface quality requirements, shape is not allowed to leave a visible trace. Performance of this paper describes the switch car seat materials, project selection, rational use of side core-pulling structures, launched body option and a plastic molding process design and die design and manufacturing process, and more, using UG software for a simple three-dimensional modeling, using CAD software for two-dimensional composition, and eventually finished. Plastic parts on the basis of the analysis of the basic characteristics of the determined casting system and type, to determine the optimum casting system. Through the analysis of the side body, to determine the final side core-pulling mechanism to design the best forming program, complete the task.
Key words: Automotive switch; Side core-pulling; Inject mold
