摘　　要：根据对压铸件结构形状的分析,确定分型面、抽芯及开模方式。由于零件的较大部分壁厚较薄(仅1 mm)的特点,谨慎分析及详细包紧力和零件的强度计算,制定零件的顶出方案,浇注系统及压铸过程中铝液充填模腔的状态分析和排气系统的设计,最终确定模具结构。既保证了顺利顶出零件,又保证了零件的尺寸精度。According to the analysis of the shape of die casting structure, the parting surface and core pulling and open mold were determined. According to the parts with thin wall thickness only most features of 1 ram, the ejection process, pouring and exhaust system of parts was determined, by analyzing package parts and strength calculation carefully, the filling mould state of melt aluminum, the mould structure was finally determined. The process can ensu re the parts being pushed out smoothly, and guarantee the dimensional accuracy of parts.
