机油滤清器支架压铸模设计

Design of Die Casting Die for Oil Filter Bracket

分析了机油滤清器支架压铸件的工艺性,介绍了该模具的结构设计、分型面选择、动定模设计和推出机构设计等。为了制造和使用方便,对模具的动定模结构进行了倒置设计,即包紧力大的、形状较复杂的型芯部分设计成定模,而成型外表面的型腔部分设计成动模,还专门设计了3个工艺挂台,并在侧抽芯上设置了推出机构,从而减小了模具体积,降低了模具制造成本。

The structural design, parting surface selection, container and moving mould design as well as push mechanism of die casting die have been expounded based on analysis of processing performance of oil filter bracket. To the convenience of manufacturing and application, an upside-down design for the container and moving mould structure was conducted, namely, core with large close force and complex shape was designed as container and cavity for forming surface was designed as moving mould. In addition, three processing concaves were designed and push-mechanism was set at side-core-drawing, which can reduce mould volume and decrease manufacturing cost of the die.
