- 摘要:
- 针对有厚大法兰、整体壁厚较薄以及内腔形状比较复杂的箱体类零件的铸造工艺进行了研究。此类箱体采用外部金属型,内腔由覆膜砂芯形成的金属型重力铸造方式铸造。内腔分型方式不同,会对铸件的内部和外在质量产生很大影响,并影响铸造生产操作的难易程度。结果表明,经过对各种方案的分析比较和实际验证,确定了最佳金属型重力铸造工艺。The casting technology of box-type parts with large flange, thin wall thickness and complex cavity shape was studied. This kind of box body casting with the external metal mold, the inner cavity was formed by the coated sand core metal mold gravity casting method. The internal and external quality of castings would be greatly affected by the different ways of cavity parting, and the degree of difficulty of casting operation would also be affected. The results show that the optimum gravity casting process of metal mold is determined after the analysis and comparison of various schemes and the actual verification.
