摘要:

为预测注射模具在给定的冷却管道分布下型腔表面的温度分布情况,使用边界元法进行注射模的温度分析.对于注射模温度场问题,边界单元法具有数据准备量小、计算量小、精度高等优点.但由于注射模内部型腔为一狭缝,冷却孔长度远大于其直径,普通的边界单元法无法进行计算.根据注射模的结构特点,推导出适用于注射模冷却分析的边界积分方程,并给出模具三维温度场的边界元计算方法.实践表明,该软件对注射模冷却系统的分析和设计具有较好的指导作用.

Abstract:

In order to predict the temperature distribution of the cavity surface of the injection mold under the given cooling channel distribution, the temperature analysis of the injection mold is carried out by the boundary element method. For the temperature field problem of injection mold, the boundary element method has the advantages of small data preparation, small calculation amount and high precision. However, since the cavity inside the injection mold is a slit and the length of the cooling hole is much larger than its diameter, the ordinary boundary element method cannot be calculated. According to the structural characteristics of the injection mold, the boundary integral equation suitable for the cooling analysis of the injection mold is derived, and the boundary element calculation method of the three-dimensional temperature field of the mold is given. Practice shows that this software has a good guiding effect on the analysis and design of injection mold cooling system.
