摘要：本文论述了一种单浇口位置优化注塑模具的方法。客观的浇口优化，尽量减少注塑制品翘曲变形，因为翘曲是一个关键质量问题，对大多数注塑件，这绝大部分受浇口位置影响。专题翘曲的定义是用比例最大位移对特征表面预计长度的表面特征来描述零件翘曲。优化相结合，数值模拟技术，以找到最佳的浇口位置，其中，模拟退火算法就是用来寻找最佳的浇口位置。最后，其中一个例子是讨论有关文件，并可以得出结论认为，所提出的方法是有效的。

Abstract:
Abstract:   This paper deals with a methodology for single gate location optimization for plastic injection mold. The objective of the gate optimization is to minimize the warpage of injection molded parts, because warpage is a crucial quality issue for most injection molded parts while it is influenced greatly by the gate location. Feature warpage is defined as the ratio of maximum displacement on the feature surface to the projected length of the feature surface to describe part warpage. The optimization is combined with the numerical simulation technology to find the optimal gate location, in which the simulated annealing algorithm is used to search for the optimum. Finally, an example is discussed in the paper and it can be concluded that the proposed method is effective.
Key words:  Injection mold, Gate location, Optimization, Feature warpage.
