摘　　要：以钨钼合金作为模芯材料,将叶轮壳体型腔的面轮廓度精度控制在0.1 mm之内;合理利用了动模框下部的有限空间,解决了弧线进气管包紧力大、脱模困难的问题。本压铸模具设计对类似结构的汽车零部件开发具有极高的参考意义与应用价值。The profile accuracy of the impeller cavity in the turbocharger housing is controlled within 0.1 mm by using tungsten-molybdenum alloy as the material of die-casting die. The limited space at the lower part of the movable mold frame is rationally utilized to solve the problems of high clamping force and difficult die release for the arc-shaped inlet pipe of the turbocharger housing. The design of this die-casting die has a very high reference significance and application value for the development of automobile parts with similar structures.
