我们将凹模,凸凹模,固定板,卸料板一类零件简称为模板类零件。这些零件是冲裁模的主体部分,它们的设计是模具设计的关键,同时也是模具CAD/CAM中较难处理的部分,这方面可供参阅的国外资料很少,从国内已经通过鉴定或报导过的几个模具CAD系统来看,图形输出大都采用了二维图形处理的方法,依靠人机交互的方式, We will die, punch and die, fixed plate, a type of stripper plate referred to as the template parts. These parts are the main part of the blanking die, and their design is the key to die design, but also the mold CAD / CAM more difficult to deal with the part of foreign information available for reference rarely, from the country has been identified or reported A few die CAD system point of view, most of the graphical output using a two-dimensional graphics processing methods, relying on the way of human-computer interaction,
