Has good resistance to impact, mechanical properties is relatively strong, with a variety anic solvent and acid and alkali corrosion resistance. Has wide application in industry, is one of our mon polymer materials. Now the mold has e the foundation for the development of the industry, however, the plastic mold accounted for 37% of the total mould, plastic molding didn't die in life occupies a very important part of the application field, along with our country economic development, the plastic products production is more and more widely, plastic ever sex industry growing status in the industry. The graduation design through the analysis of plastic parts for manufacturability parison to understand what the cover plastic mold production process and working principle. The subject, the basic principle of the injection molding are introduced from several aspects, the size of plete parts calculation to mold action process, including the selection of 买文档送 CAD 图纸, QQ 36396305 injection machine, position of gating system, and has proved to mold strength requirement, more detailed study of the cover of plastic injection mould design. Through the design, make me to plastic injection mould has a preliminary understanding and insights, which also noticed the details in the proc
