摘要：

根据空调蒸发器边板零件的结构特点及实际生产的技术要求，进行多工位级进模排样设计。考虑到零件结构及边距因素，最终设计了8工序的模具结构。根据工件外形特征选用了单排排列，在保证了材料利用率的同时，也使工序达到最简化。模板与模板之间设计了销钉定位，保证了模具的精度，从而使零件各工序的加工变得更加精准。在凸模和凹模合模碰撞的地方设计了橡胶圈，使得每次冲裁时均有缓冲，保证了模具的寿命。工序的第1步即为设计冲定位孔，保证了送料的精度。经过实际生产验证，该模具使用性能稳定、产品质量良好，满足了大批量生产的需求。

According to the structure characteristics of side plate parts for air conditioning evaporator and the technical requirements of actual production, the layout design of multi-station progressive mold was carried out, and considering the structure and margin factor of parts, an eight-process mold structure was designed finally. According to the features of workpiece shape, the single-row arrangement was selected to ensure the utilization rate of material and simplify the processes to the greatest extent, and the pin positioning was designed between templates to ensure the accuracy of mold, so that the processing of each process for parts became more accurate. Furthermore, the rubber ring was designed at the place where the punch and die collided, so that there was a buffer during each blanking, and the service life of mold was guaranteed. In addition, the first step of the processes was designed to punch the positioning hole, which ensured the accuracy of feeding. The actual production verification shows that the mold has stable performance and good product quality to meet the needs of mass production.
