计算机辅助工程技术在塑料注射成型中的应用

摘要

This paper explores the plastic molding process and mold structure design by means of computer-aided engineering(CAE), which can be used for problem-resolving during simulation in mold design, and determines the required process parameters with the help of computer simulation. Process parameters of plastic injection mold are chosen to integrate with mold structure. Case studies show the application of CAE in simulation of plastic molding and mold structure design, which proves to be successful in modifying the quality of products.%利用计算机辅助工程技术对塑料注射成型工艺及其模具结构设计进行了探讨。计算机辅助工程技术能够在模具设计阶段开展模拟工作，一旦发现问题，则会及时解决，同时也能运用计算机模拟并确定注射成型所需的工艺参数。通过选择塑料注射成型工艺参数，力图将工艺参数与模具结构紧密融合。最后，用实例验证了运用计算机辅助工程技术模拟注射成型工艺及模具结构设计的过程，达到了提高注射成型制品质量的目的。
