空调垫片倒装式复合模设计 摘要 本模具为空调垫片冲孔落料复合模,在设计时:1、接受任务书；2、调研消化原始资料；3、选择成形设备；4、拟定模具结构方案；5、方案的讨论与论证；7、绘制模具装配图；8、绘制零件图；9、编写设计说明书；10、模具制造试模与图纸修改。正确的确定模具成形零件的尺寸。冲孔凸模、落料凹模、凸凹模等零件是确定制件形状、尺寸和表面质量的直接因素，关系甚大，要特别注意。模具的设计应制造方便,尽量做道使设计的模具制造容易、造价便宜。特别是比较复杂的成形零件，必须考虑是采用一般的机械加工方法加工还是采用特殊的加工方法加工。模具的设计应当效率高、安全、可靠。模具零件应耐磨耐用。 关键词：模具、成形、冲孔凸模、落料凹模、凸凹模。 Pierci
