摘　　要：以某汽车变速箱悬挂端盖为对象,研究其采用压铸时可能出现的气孔、缩松等问题。首先对零件需求进行分析,然后完成浇排方案和水路排布方案设计,形成初步模具设计方案。采用华铸CAE模拟及试模对模具设计方案进行验证,对气孔缺陷产生的原因进行分析。最后通过增加挤压销结构并控制冷却水温的方式成功解决了气孔、缩松等缺陷。An automobile transmission suspension end cover was analyzed to understand the porosity defects and shrinkage porosity caused by die casting.Firstly,the part requirements were analyzed,then the goting-exhausting system and waterway layout scheme design were carried out to form the initial mold design scheme.The mold design scheme was verified by InteCAST simulation and the actual production,then the causes of porosity defects were analyzed.Finally,by increasing an extrusion pin structure and controlling the cooling water temperature,the porosity defects and shrinkage porosity were successfully eliminated.
