摘要
基于模流分析,利用田口(正交)试验方法对汽车门把手的气体辅助注射成型工艺进行优化,使其达到最优的初始气体穿透量,得到合格的制品。选择注气时间、注气压力、注气延迟时间、预注射量4个主要因素进行正交模拟试验。用四因素三水平正交试验表进行模拟试验设计,采用方差分析法研究了这4个因素对初始气体穿透量的影响,得知其中影响较大的因素是预注射量。对气体辅助注射成型工艺进行优化,为改善制品质量、得到合格穿透深度的制品提供指导,从而缩短试模时间,提高生产效率。
Based on the mould flow analysis,the gas-assisted injection moulding process of the car door handle was optimized by using Taguchi（orthogonal）experiment method,which achieved the optimal primary gas penetration and obtained the qualified products.In this paper,the orthogonal simulation test was carried out with four main process parameters,including gas injection time,gas injection pressure,gas injection delay time and pre injection volume.The design of simulation experiment was carried out by using the three-level four factors orthogonal experiment table.The influence of these four factors on the primary gas penetration was studied by the method of analysis of variance,and the most significant factor is pre-injection volume.The gas-assisted injection molding process is optimized to provide guidance for improving product quality and obtaining qualified penetration depth.It is useful for shortening the cycle time and improving production efficiency.
