摘　　要：以某计价器上、下盖的压铸模设计及制造为例,分析了该铸件的成形工艺,详细介绍了该铸件压铸模的分型面、浇注系统及排溢系统、脱模机构、冷却系统等设计,叙述了该铸件的模具结构与工作过程,剖析了其压铸模的数控加工工艺流程和技巧。实践证明,该铸件的模具结构设计及数控加工工艺合理,模具的CAD/CAM一体化设计缩短了铸件开发周期,确保了铸件质量,对同类压铸模的机构设计和数控加工具有实用参考价值。Taking the design and manufacture of the die-casting die for the upper and lower covers of a certain fee meter as an example, the forming process of the castings is analyzed. The design of the parting face, gating system, overflow system, and the demolding mechanism as well as the cooling system of the die-casting die are introduced in detail. The die structure and working process of the casting are described. The NC machining process and skills of the die-casting die are expounded. Practice proves that the die structure design and NC machining technology of the castings are reasonable. Application of CAD/CAM integrated technology in die design make the development cycle of the castings shortened and the quality of the castings improved. It has a practical reference value for the mechanism design and NC machining of the same kind of die-casting dies.
