基于边界元法的注塑模温度调节系统优化设计

The Optimal Design of a Temperature Adjusting System for Injection Molds

通过对时间域和空间域的离散，运用边界元法，求解模具在成型过程中的三维温度场及冷却时间，在此基础上对注塑模的温度调节系统进行优化设计．实际应用表明，基于温度场模拟分析的结果进行温度调节系统的设计，更为准确。

In contrast to the conventional empirical design mode, discretization is performed of the space and time domains. A three dimensional numerical scheme using the boundary element method (BEM) has been developed to solve the cooling time and the transient temperature field during mold forming. The derivation of a series of boundary integration equations are described in detail. The mold designer will be able to update a previous design until a proper temperature adjusting system for the injection molds results, which is crucial to better product quality and higher productivity.
