摘　　要：针对当前注塑模具顶针传统手工排位设计存在的问题,提出了一种顶针自动排位设计的方法。该方法通过对模具凸模成型部分最大轮廓线和窄槽特征的识别,自动给出顶针的具体位置,基于NX软件开发了顶针快速设计系统。实践表明,该系统操作简单、实用性强,在一定程度上实现了顶针设计的自动化,提高了模具设计的整体效率。In view of the problems existing in the current design of injection mold ejector pin by manual positioning, a method of automatic placement design of thimble is proposed, which can automatically give the specific position of thimble by identifying the maximum contour line and narrow groove feature in the forming part of die punch. Based on NX software, a rapid design system of thimble is developed. The practice shows that the system is simple and practical, which can realize the automation of thimble design at a certain extent and improve the overall efficiency of mold design.
