摘要
对注射成型过程中常见的成型缺陷(如短射、滞流和沉降斑)的形成原因进行了分析。从模具设计、工艺参数设置和塑料材料选择三个角度提出了解决问题的办法。进而用商业化CAE软件对这三种成型缺陷进行了数值模拟,探讨了模具设计、工艺参数、材料对成型缺陷的影响程度和改进方案的可行性。
The cause of usual molding fault in the course of injection forming, such as the short shot, the viscous flow and the sedimentation tache, was analyzed. Then methods of resolution in- volving the mold design, the setting of technological parameter and the selection of plastics was put forward. Commercial software CAE was further used to numerically simulate these three molding fault.The influence of the mold design, the technological parameter and the plastic material on the molding was explored. The feasibility of improvement was discussed as well.
