PAGE PAGE 6 摘 要 本设计论文系统阐述了汽车轮帽塑料注射模设计过程，根据汽车轮帽塑件的形状和生产要求，编制汽车轮帽塑件的设计过程，初步制定了总体模具的设计方案。论文首先对汽车轮帽塑件进行了详细的工艺性分析，然后进行注射模结构设计，比如分型面的选择，抽芯机构的设计等，并进行模具设计的相关的计算,完成型腔和型芯工作尺寸的计算等，接着对整个模具的进行相关校核，最后完成整个汽车轮帽注射模设计，并绘制出模具的总装图和非标准件的零件图。 本设计方案结构紧凑，满足制品大批量生产、高精度、外形复杂的要求，设计参考了以往注射模具的设计经验，并结合制件性能，简化设计机构，并且运用AutoCAD等软件进行绘图，缩短了生产周期，并且获得良好的经济性能。 关键词：汽车轮帽；注射模设计；硬聚氯乙烯；侧向抽芯 Abstract The thesis systemic introduce the design process of the plastics injection mould of four-way pipe, base on the shape and the production requirement of four-way pipe, at the same time the article establish the design process of four-way pipe produce, and elementary set down the design scheme of the total injection mold. The four-way pipe produce adopt single cavity of injection mould design，use the mechanism of liquid pressure lateral loose core and incline leader lateral loose core,and the mechanism of handspike. First, the thesis analyse the craft of the four-way pipe produce particular, then finish the structure design of four-way pipe injection mold, such as the choice of the parting surface, the design of lateral loose core structure etc.. Second, the paper finish the calculatione related with the injection mold design, for example the calculation for the work size of the cavity and core. Third, the article complete the parametric relate with the whole injection molding checking. Finally, the thesis complete the design of the whole four-way pipe injection mold, and draw the total assembly chart and the accessory chart of the non-standard of the mold. This design is compactness for fulfilling volume-produce, demand with complicated high accuracy and appearance, at the same time references anciently experience of injection mould and combines characteristic of produce to project organization simplify the project organization. In order to shorten production cycle and obtain favorable efficiency, the two-dimension and triaxiality drawings were finished by AutoCAD. Key words：four-way pipe; injection mould desig
