At first, under the pieces of plastic materials and process characteristics with software pro / e for model analysis, then choose injection molding machine and to determine the number of cavity, then determine forming programs : overall structural design, type design, gating system design, ejection mechanism design, design of the cooling system .Finally checking processing parameters of the injection molding machine, including the injection volume, clamping force, injection pressure, thickness and injection mold machine closure using the right software MasterCAM molding parts NC to determine tool paths and processing methods, Simulation of their processing 。 Keyword: injection mold NC mold design MasterCAM 塑料衣架模具的設(shè)計(jì)和典型模具零件的數(shù)控加工 第 3 頁(yè) 共 65 頁(yè) 目錄 0 引言
