基于UG NX的旋盘件侧抽芯模具设计
摘要
此设计是基于NX的旋盘件侧抽芯模具设计,设计的总体部分可以大致分为分型面的选择、侧向抽芯的设计、模架的选择、浇注系统的设计、冷却系统的设计、脱模系统的设计。本次设计的要点:此设计在注塑成型时,型腔内壁有一个凸台,必须要使用侧抽芯,以便于零件的成型和脱模。型腔的内侧有一个阶梯状的凸起,需要进行镶块设计。因为在实际生产中会对型腔形成冲刷,阶梯状的结构形成的型腔就容易损坏,因此需要设计镶块以便于更换和减少制造成本。此次设计最重要的一点就是更清楚的表达模具的内部结构,因此会附上设计时保存的结构图,局部放大图,还有模具的爆炸图。
关键词:塑件设计;旋盘式零件;侧抽芯设计
