摘要:

使用 COMSOL Multiphysics 有限元仿真软件对盘式螺杆微注塑机中的旋转盘式螺杆的塑化加工过程进行仿真研究。在螺杆旋转运动时,分析塑化单元中聚合物的流动与传热相变情况。结果表明,在螺杆结构不变的前提下,主要工艺参数中加热温度对塑化性能的影响较大,螺杆转速的影响较小。同时基于仿真结果,对盘式螺杆的下一步结构优化提供参考依据。

Abstract:

The plasticizing process of a rotating disc screw in the disc-screw micro injection molding machine was simula-ted by using the COMSOL Multiphysics finite element simulation software. The phase change of polymer flow and the heat transfer in the cavity were analyzed during the rotation of the screw. The analysis and simulation results indicated that the heating temperature had greater impact on the plasticizing performance under the premise of the same screw structure, and however the rotate speed had a smaller impact on the plasticizing performance. Base on these simulation results, this paper provides a reference for the structural optimization of the disc screw.

Key words: finite element simulation, micro injection molding, plasticization, disc screw
