目前我国已成为世界上卫生洁具的最大生产国和消费国,然而国内陶瓷企业对卫生洁具模具的开发制作至今还是传统的手工作坊形式,这种制作方式已成为影响陶瓷企业进一步发展的瓶颈。本文对以UG软件为平台的卫生洁具产品的模具CAD系统进行了研究和探讨,并以坐便器模具为例,阐述了在UG环境下卫生洁具模具CAD系统的面向对象设计技术和程序的具体实现方法,将UG软件的二次开发技术与石膏模的生产工艺结合起来,在国内首次开发专用的坐便器模具CAD系统,是对CAD技术专业化应用的开拓与实践,有利于实现卫生洁具模具制造业的信息化生产。

China has become the largest country in produce and consumption of sanitary wares at present.However,in the domestic ceramic enterprises,manual modeling is still widely applied in the developing process of the mould of sanitary wares.This mode of craft workshop-based mould manufacture has become the bottleneck of ceramic enterprise's further development.In this paper,the authors study and discuss mould CAD system for sanitary products based on UG software,and take the gypsum mould of closestool as an example,describe the technology of OOD and concrete realizing method of program based on UG software.On the basis of combining the further development technology of UG software and production technology of the gypsum mould together,the authors develop the special-purpose toilet mould CAD system that is based on software Unigraphics for the first time at home.It's a development and practice of the professional application of CAD technology,and is helpful for realizing the informationized production of toilet moulds manufacturing industry.
