铝壳体压铸模具设计
摘要：压铸是制造业的一种工艺，能够成型复杂的高精度的金属制品，多用于汽车制造，机械制造等。本课题是对铝壳体进行模具设计并分析加工工艺。
本模具考虑到年产量、工厂的设备及铸件的精度要求，选择一模一腔结构。以制品的最大端面为分型面,使制品顺利脱模。制品上还有散热片，须进行侧向抽芯。为了使动、定模能够准确地动作, 导向定位机构利用导柱与导套的配合。顶出机构是推杆推出的一次脱出机构。考虑到零件的位置关系,冷却水道采用循环式分布，以便冷却均匀、快速。
$ ^6 G1 U7 A9 q/ k采用Pro／Engineer、AutoCad来实现铝壳体的三维设计及模具成型零件设计，分析制件的成型质量和完成分型面的设计，再采用EMX组件来实现模架的装配，并在产品设计及模具装配过程中，辅助以必要的理论计算，将数字化设计与理论计算结合起来，可以大大缩短产品研发周期、模具设计周期，提高产品设计及模具设计的准确性、产品成型质量，降低产品研发、模具设计成本。在设计过程中制定了合理的工艺方案，满足了大批量生产要求。同时，还编制了详细的工艺文件来保证模具的顺利加工及制品的生产。

  M. g! W7 M' {- t3 [' L& vAbstractie-casting is a manufacturing process,it can mold the complex and high accurate metal product ,used in automobile manufacturing, machinery manufacturing and so on. The subject is about the design of Aluminum shell mold and process analysis.
    Considering the annual output, the equipmen of the factory and the requirement of precision of the plastic product,one cavities in a mould. Thelargest surface of the goods was choosed as the parting line to make goods by demold successfully. The products have heat sink,so it need lateral core pulling. Suspension and Positioning mechanism use matched guide pillar and guide sleeve to make movable mould, fixed mould to work accurately. The knockouts uses once ejecting mechanism that lifter pushes out. By the relation of the position of each part, cooling channels are designed to straight channels to cool effectively, quickly.
With Pro/Engineer,AutoCad to implement three-dimensional design and mold volume design of the telephone receiver, and shaping quality of part was analyzed and the parting line was designed by Pro/Engineer, then utilized EMX to accomplish the assemblage of the mold with the assistance of essential theory calculate mixed with figure design. It would not only shorten the cycle of product research and mold design, and improve the preciseness and the product shaping quality, but also lower the cost of the research. Having made the rational craft scheme in the design process ,so it has met the requirement of producing in enormous quantities. Moreover, it also prepared a detailed document to ensure that the process for the smooth processing of mold and apparel production.
