摘　　要：通过对高强度ZQCuCo3CrRE铜螺母铸件缝隙式内浇道的优化设计,在生产中确定了金属型双坯对开模具缝隙式内浇道的厚度和高度,并对浇注温度、充型速度和开型时间等提出要求,证明铜螺母铸件采用缝隙式内浇道工艺具备质量稳定,生产效率高,操作简单可靠等优点,是铜螺母铸件较为有效的铸造工艺。Through the optimization design of the vertical-gating of high strength ZQCuCo3CrRE copper nut castings, the paper defines the thickness and height of opening mold slotted gate with metal-type double billets in the production and puts forward the requirements for pouring temperature, filling speed, opening mold time and so on. The copper nut castings with vertical-gating was proved to have the advantages of stable quality, high production efficiency, simple operation etc, and it was vindicated to be a more effective casting process for copper nut castings.
