基于cimatron的豆浆机上盖模的设计及凹模的高速仿真加  
工
摘要：注塑模具目前在塑料模具中使用最广泛，能够成型高复杂度、高精度的塑料制品。本课题是对豆浆机上盖模具进行设计并分析其加工工艺。
本模具考虑了年产量、工厂的设备及塑件的精度要求，最终选择一模一腔结构。以制品的中间水平面为分型面,使制品顺利脱模。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。
采用Pro／Engineer、cimatron来实现豆浆机上盖模具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。
    经实践检验，本模具满足生产与应用的要求。

The Design and Manufacturing of the top cover beanstalk Receiver Mold Simulation of die processing base in cimatron
Abstract：At present ,injection molding is the plastics mould that has being used  most extensively , it can mold the complex and high accurate plastic product. The Subject is about the design of the top cover beanstalk receiver’s mold and process analysis.
Considering the annual output, the equipment of the factory and the requirement of precision of the plastic product, one cavities in a mould. The middle horizontal surface of the goods was choosed as the parting line to make goods by demold successfully. The runner is designed to be balanced and symmetrical distribution, ensure that melting plastic could reach each cavity’s gate almost.. 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, cimatron to implement three-dimensional design and mold volume design of the junction box, 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.
By practice, it has meet the production and application of the requirements.
