【摘要】 本文针对注塑成型过程中注射压力的优化及预测问题,应用注射过程流动模拟软件HSCAE3DRF5.1及三维实体造型软件PRO/E2000i,以洗衣机后挡板注塑件为实例研究对象,组织注射压力和注射时间的输入输出参数样本,建立灰色GM(1,1)模型,同CAE模拟结果比较,其误差在允许的工程误差范围之内,证实了该模型在注塑压力优化和预测中的可行性.更多还原

【Abstract】 This paper aims at studying the optimization and prediction of injection pressure during the injection molding process.Based on the simulation software of the filling flow HSCAE and the three-dimensional modeling software PRO/E,using the backboard of washing machine as the object of study,the input and output parameters of injection pressure and time are collected,and a GM (1,1) model is built.Its results are close to those from CAE analysis,and its error falls within the engineering-permitted error range.This proves the applicability of the Grey Model in the optimization and prediction of the injection pressure during the injection molding process.更多还原
