摘　　要：提出了一种自动生成模具分型面的方法 .首先根据模具的脱模方向和分型线 ,对分型线的凸凹性进行识别与预处理 ,得到优化的分型线 ,然后将组成分型线的线段按类型进行分组 ,并按照不同的规则 ,生成一系列连续的面片 ;最后通过面片缝合生成分型面 .实例测试表明 。An automatic parting surface generation approach in injection mold design was presented. Firstly, it recognizes and pretreats the shape of the parting line according to the parting direction and parting line, and results in an optimized parting line. Then, it classifies the segments of the parting line by their types, and generates a serial of face pieces based on different rules. Finally, it gets the parting surface by sewing these face pieces. The test results show that the proposed approach is effective and efficient in automatically generating the parting surface of the molded part.
