Abstract

During the filling stage of injection molding, important thermal phenomena take place in the mold feeding system. We present a non-isothermal model for the flow through the runners and the gates that permits us to accurately simulate the filling of thermoplastics parts. Comparison with experiments demonstrates the validity of our approach.

热塑性塑料注射喂料系统的计算与优化
在注射成型的充型阶段,在送模系统中会发生重要的热现象。我们提出了通过流道和浇口流动的非等温模型,使我们能够准确地模拟热塑性塑料零件的填充。实验结果表明了该方法的有效性。
