Abstract：

According to the structure characteristics of the auto water pump impeller, the mould structure for powder metallurgy process was designed and the compacting process and key points for mould designing, manufacturing and debugging were presented in details. Because the impeller blade was an open discrete shape, the loading power was realized by eight petal inhaling method. Further, the floating method was used when the power was compressed, and the auxiliary cylinder ejected the part when it was demoulded, and the impeller could be shaped at one-time. Through the process of sintering, machining, cleaning, polishing, oil treating, all the aspects of final products such as material density, hardness and precision of the technical indicators could satisfy the customers requirements, so the imported products could be substituted. The design of compacting mould structure was reasonable and the quality of part could be ensured. Finally, it works well in real manufacturing situations, and the design requirement could be met.
