Abstract
This article discusses the plastic protective cover of plastic mold design, which also introduces the related technologies, theories and methods when designing injection molds. Mold design is the use of software CAXA electronic board 2013 to paint, draw the mold assembly drawing, side slider, pusher plate, set the template, move the template part in FIG. This paper analyzes the injection mold design process, the design step includes: reading parts diagram, process analysis, to determine the mold structure, structural design calculations, Assembly Drawings, parameter calibration; including the mold structure determination of the injection molding machine type selection , gating system design, design-oriented and positioning mechanism, and the design and calculation of cooling channels molded dimensions and the like. Finally, by Moldflow simulation software for plastic parts best gate location, filling time, welding marks distributed, cavitation pressure distribution analysis, forecasting product that may occur during the injection molding problems.
