摘要：为了在一副模具上实现对客车后侧门上1 000多个长圆形散热孔的冲孔加工，采用了跳孔的工艺方案和快换凸模的模具结构，解决了散热孔孔距小、模具强度不够的问题，并能快速地适应不同车型的生产，很好地解决了客车后侧门批量小、手工又无法加工生产的问题，是模具低成本投入的一种方法，对设计和制造符合小批量生产的模具，具有很好的借鉴作用。

Abstract: In order to punching cooling holes of more than one thousand in the rear side doors of the bus on one die, a processing plan skipped hole and die structure of up die changed quickly were introduced. The problem of punching cooling holes that were close was solved. The strength of the die was improved. The rear side doors of different type were produced. The problem of the rear side doors were low yearly yield and couldnt be produced by handwork was solved well. It was a way that spent less money in manufacturing a die. The die was designed and manufactured for small batch produced, It had a good reference function.
Key words: rear side door; processing plan; die structure
