摘要
近几年，随着机械工业的发展，注射模具制造技术在国内外得到了快速发展，注射模具应用的领域越来越广泛。同时人们对注射模具设计的快速性和合理性以及产品的质量要求越来越高。
目前国外模具行业广泛采用CAD/CAM技术，并通过3维设计软件设计和仿真，大大的缩短了产品开发周期和制造周期，提高了模具的技术含量，降低了成本。相比之下，我国模具行业还有很大差距。针对目前注射模具行业的情况，我们必须根据国际模具工业的发展，综合分析国外经验，结合我国实际情况，采取有利措施，提高我国注射模具工业的竞争力。
本课题通过对卡通饮水机底座的分析，以UG、AutoCAD软件为基础，进行了卡通饮水机底座塑件模具的设计，利用参数化实体造型的方法，突破了AutoCAD3维实体造型功能不足的局限，为注射模具设计、加工和生产提供了1种切实可行的办法。本课题取得了比较满意的效果，达到了预期的设计意图。

Abstract
In recent years，with the development of manufacturing industry，an injection mould which was widely applied in many fields was been developed fast．Meanwhile，the higher requirement of the rapidity and rationality of the injection mould was proposed．
With the application of 3D design software and simulation，the lead time of a mould was shortened with an increase in technology content as well as a reduction in cost in foreign nations．While the development status at home was not very good．In terms of increasing the competitiveness of injection mould industry，foreign experience and development must be learned and effective measures should be taken．
After the analysis for the plastic the base of cartoon water supply machine，the injection mould of the base of cartoon water supply machine was designed by modeling created by parameters based on UG and AutoCAD．So the functional defect of 3D modeling based on AutoCAD was avoided and a feasible method for the design and manufacture of the injection mould was approached．In this paper，the desirable results and expected design were achieved．
Key words：injection mould；UG software；mould design；drinking fountains；
