Abstract
With modern industrial development, the plastic products industry, are widely used in agriculture and daily life, and other fields, also the quality requirements have become more sophisticated. In plastic products, the production and quality of mold design, advanced mold manufacturing equipment and reasonable processing, die quality materials and modern equipment are molding quality plastic parts forming an important condition.
This paper discussed the design of plastic injection mould of Switch lid. Use PRO\E EMX4.1 module function of the characteristics of the products for mold design. The author determined the parting surfaces and the gating system and Release the organization, cooling system etc, choosed the injection molding machine，calculated the sizes of the molding parts. adopted to sprinkle directly in the design, make use of to keep lead the pillar direction fixed position, push the pole crest to anticipate, and carried on the choice to the material of the molding tool. According Switch lid injection mold parts to the requirements of the injection parameters of the machine was calibrated. And the author also drew a set of mold assembling chart and parts chart using AutoCAD software. And carries on the numerical control processing with the Mastercam software to the core die space
