Mold material is the basis of the mold processing industry.In pace with China's national economic development and improvement of living standards, people's aesthetic values on products is also rising, so all kinds of work, mold products, not only on internal quality but also onl beautiful appearance require to be perfect, Therefore,higher requirements must be proposed on amount,series and quality.
This paper introduce the injection mold design of Dongan car leaves box pinch. Discuss plastic molding process characteristics,plastic injection molding process and control, matching plastic injection machine,plastic parts of the extrusion mechanism design, the number of sub-surface and cavity design, process characteristics of ABS plastics in detail. design of punch die structure , casting system,the design air exhaust system, selection of mold.I hope when I finish the research, I can accumulate more experience in the design.
