基于缩痕最小的注塑件成形工艺参数优化设计

摘要

To minimize the sink marks on the injection molded parts of automobile hand brake cornice, the forming processing in mold cavity was analyzed with Moldflow software. Based on the minimization of the product surface sink index, the reasonable gate location , gates numbers and optimization parameters such as mold temperature and melt temperature were gotten. Based on these optimization parameters, the cycle of mould development is shortened, and the quality of products and the competitive ability of company are improved.%针对汽车手制动檐口在注塑过程中出现的缩痕问题,借助Moldflow软件模拟其注射成型过程,得到了基于注塑件表面缩痕最小的最佳浇口位置、数量、模具温度和熔体温度等工艺参数.据此进行模具设计,可缩短模具开发周期,提高产品质量和企业竞争力.
