摘要：注塑模具是现在所有塑料模具中使用最广的模具，能够成型复杂的高精度的塑料制品。本课题是对塑料瓶盖模具设计并分析加工工艺。
本模具考虑到年产量、工厂的设备及塑件的精度要求，选择一模四腔结构。以瓶盖主体和防伪圈之间的面作为分型面,使制品强制脱模。流道采用带环形冷料穴，脱模时方便将主流道凝料和塑件带出，确保熔融塑料几乎能同时到达每个型腔的进料口。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／E来实现塑料瓶盖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CIMATRION来实现其数控仿真的加工，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。
通过合理的设计，本模具满足生产与应用的要求。

The Design and Simulation
Processing of Mold for Plastic Caps
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 plastic caps and simulation processing.
Considering the annual output, the equipment of the factory and the requirement of precision of the plastic product, four cavities in a mould. The middle horizontal surface of the goods was To cap the main circle and security between the surface as a type face, so that mandatory Stripping products. 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,MoldFlow to implement three-dimensional design and mold volume design of the Plastic caps, and shaping quality of part was analyzed and the parting line was designed by Pro/Engineer, then utilized CIMATRION 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.
Through the rational design, It has meet the production and application of the requirements.
