摘　　要：介绍在DISA垂直造型线上生产球墨铸铁行星架的一种工艺方案。通过对产品结构分析及计算机铸造模拟仿真分析,确定分型面选择、砂芯设计、浇注系统和冒口等工艺方案。对热节位置进行了合理的补缩设计,大端面利于冒口补缩实现顺序凝固,小端面可利用石墨膨胀自补缩,避免缩孔缩松缺陷。试生产结果显示铸件质量合格,金相组织和力学性能符合标准,无缩孔缩松缺陷,证明该工艺方案可行。This paper introduces a process scheme for producing ductile iron planetary carriers on the DISA vertical molding line.Through product structure analysis and computer casting simulation analysis,the casting process scheme is determined,covering aspects such as parting surface selection,sand core design,pouring system and riser design.Reasonable feeding design for hot spots is carried out.The large end face is conducive to sequential solidification with riser feeding,and the small end face can utilize graphite expansion for self-feeding to avoid shrinkage porosity defects.The trial production results show that the casting quality is qualified,the metallographic structure and mechanical properties meet the standards,and there is no shrinkage porosity,proving that the process scheme is feasible.
