注塑模型腔加工电极CAD技术

THE COMPUTER AIDED DESIGNING CAVITY ELECTRODE OF INJECTION MOLD

在注塑模的设计和加工过程中,型腔加工较为常用的方法是电火花加工。而电火花加工的关键是符合要求的电极的设计和制作。本文研究了注塑模塑件、型芯、型腔和电极的模型特点,尺寸的计算方法及塑件至型腔、型腔至电极的模型转换及尺寸转换计算公式。并给出了具体计算机辅助电机设计的实例。

The paper studies the calculation methold of the injection mold’s feature sizes including part, cavity and electrode, and studies the size transformation formula from the part to cavi-ty, from cavity to electrode. A example is given about designing electrode.
