摘 要
近年来，塑料产品和塑料模具得到了飞速的发展，应用也越来越广泛。本论文主要论述了注塑模具的发展及现状，引水机接水盒的主要设计思路、主要零部件的设计方法和计算方法。设计过程主要利用了UG和AutoCad工具软件，充分利用计算机辅助的优越性实现了设计方案。首先分析了塑件的工艺性，选择了单分型面模具，并利用UG Moldwizard模块完成了成型零部件的建模。确定了分型面、浇注系统，推出机构、冷却系统等，选择了注射机，计算了成型零部件的尺寸。并根据活塞零件注塑模具的要求对注射机的各参数进行了校核。最后用AutoCAD软件绘制了一套模具的装配图和零件图，所绘制的模具图纸对实际生产具有指导意义。

Abstract
In recent years, the plastic product and the plastic mold obtained the rapid development, the application have been also getting more and more widespread. The present paper mainly elaborated injection mold''''s development and the present situation, directs the hydraulic engine to meet Shui He the main design mentality, the main spare part design method and the computational method. The design process has mainly used UG and the AutoCad tool software, has realized the design proposal fully using the computer auxiliary superiority. First analyzed has modelled a technology capability, has chosen the single minute profile mold, and module has completed the formation spare part modelling using UG the Moldwizard. Had determined a minute profile, the gating system, the ejecting mechanism, the cooling system and so on, have chosen the injection machine, has calculated the formation spare part size. And to injected machine various parameters has carried on the examination according to the piston details injection mold''''s request. Finally used the AutoCAD software to draw up a set of mold''''s assembly drawing and the detail drawing, drew up the mold blueprint had the guiding sense to the actual production.
