the plastics injection molding design of automobile’s ail fitter shell

The monotype cavity of the plastics injection molding design according to automobile’s ail fitter shell based on Pro/ ENGNIEER software was introduced in this text, this article reads as follows :  Based on the history of the development of mold and its development trends, the plastic mold understanding of the important position, meanwhile on the subject of Pro/ENGNIEER software and Pro/ENGINEER injection mold design expert EMX (parameters of the state aircraft) in the injection mold design of the role and superiority.  Mold design of this major process：first,the use of Pro/E on plastic parts for 3D solid modeling, then design of the mold cavity ,finally,use EMX to mold design,finally application Pro/E is derived engineering drawings.  Mold design of the main analytical calculation is as follows :  Pieces of plastic material PP (polypropylene) molding process characteristics and the correct analysis to determine the number of mold cavity,sub-surface location of injection machine model, sets the size of gate, the gate design, exhaust system and the final design.      Plastic Parts of the specific analysis and calculation to determine the core cavity combinations, then the core part of the cavity analysis, as well as its connectivity components for the analysis.   According to the principles of the analysis must choose the appropriate model planes, the right mold parts of the structure for the design, including the slanting guide, slide and other derivative.
