From the plastic parts of the shape and internal structure, need two times side parting and core pulling. The upper part of the side core pulling is forming the throttle valve, and the lower part of the side core pulling and forming the outer threaded portion. From the requirements of plastic parts of the size and the product, the injection mould need high precision, it is also a difficult point of the design. From the design point of view, the threedimensional design involved, especially the application of 3D design in the mold design, the main difficulty lies in the threedimensional mold gate location and type, form, and finally the establishment of 3D assembly realization.The advanced mould CAD/CAE technology is widely used in the design of the injection mould. For example, in the design uses the Pro/E sub module, which greatly simplifies the design of the mould cavity, improves the design efficiency. And the use of Plastic Advisor in the design process, a simple analysis of the plastic parts of the cavity and runner and other important parts, the feasibility of the mold has a guiding role to a certain extent. In the design stage, using the Pro/E optimized, and the 3D assembly, the last generation of 2D part drawing, so the optimization to reduce a lot of work late.Keywords: plastic mold design, lateral type analysis, CAD/CAE, Plastic Advisor, Pro/E.第一章 任務(wù)分析第1章 任務(wù)分析本套塑料注射模具設(shè)計(jì)成型的塑件（）：塑件名稱：醫(yī)用滴液器塑件材質(zhì)：PP（聚丙烯）塑件功能：與醫(yī)用輸液管相接，控制流速塑件尺寸及質(zhì)量要求：見(jiàn)塑件圖 塑件結(jié)構(gòu)分析通過(guò)初步對(duì)塑件的三維模型以及二維塑件圖的了解，該塑件屬于超薄件，所以在設(shè)計(jì)的精度控制上會(huì)有一定的壓力，結(jié)構(gòu)還是比較典型的。塑件的長(zhǎng)度方向?yàn)?0mm，最大外
