| 摘 要： | 在分析塑料收缩率波动规律的基础上，导出了注塑模成型零件工作尺寸的概率计算公式，讨论了塑料收缩率波动范围、塑件尺寸公差、制造公差以及修模裕磨量之间的关系。研究表明，概率法计算注塑模成型零件工作尺寸比广为采用的极值计算法更为合理。

| Abstract: | A probability calculation formula used for the cavity dimension of injection mold is derived on the basis of analysing the variation rule of plastic shrinkage rate, and a quantitative relation among the variation of plastic shrinkage rate, plastics dimension tole rance, manufacturing tolerance and wear allowance is discussed. The researches show that the probability method for calculating the cavity dimension of injection mold is more reasonable than the extreme calculation method which is widely adapted now. |
