摘　　要：针对转臂铸钢件在生产过程中出现的底部夹砂、尺寸不合格,下芯后底部散砂不易清理,造型翻上盖箱时易塌箱,下芯后合上盖箱过程中,支臂处大芯子对上砂型阻挡较严重,造型合箱操作较困难等现象,对原工艺进行了改进。并通过加强工序过程的质量控制,设计合理的外冷铁和借助模拟软件验证等措施,最终生产出高质量的合格铸件。These problems appeared in producing swinging arm casting such as the sand inclusion, off size of casting, difficult cleaning of loose sand in the mould after core setting, easy occurring of flask crush, and the difficult operation of mould closing. The original process was improved, and some measures were adopted including enhancing the working procedure control, designing reasonable outside chill and verifying with simulation software, etc. Finally, the qualified castings were obtained.
