Abstract：
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.
