摘　　要：【目的】为提高注射模研发效率,可在模具制造前预测注射成型质量,以避免修模带来的成本消耗。【方法】以遥控器面壳注射成型模具设计为例,利用Moldflow软件来创建模流分析系统,进行注射成型模流分析,评估注射成型质量,并基于模流分析结果进行模具结构设计。【结果】获知产品熔体流动状态好,熔接痕少,气穴位置分布合理,塑件最大翘曲变形量为0.2668 mm,最大收缩率为5.243%,均符合产品技术要求。模具采用镶拼组合式型腔两板式结构,采用侧向滑块抽芯及多顶杆顶出脱模方式。【结论】该方法降低了模具制造的难度,保证脱模的稳定性。该方法生产的模具结构简单、运行可靠,满足遥控器外壳自动化生产要求。[Purposes]In order to improve the efficiency of injection mold research and development,the quality of injection molding is predicted before mold manufacturing to avoid the cost caused by mold repair.[Methods]Taking remote control shell injection molding mold design as an example,this paper will use Moldflow to create a mode flow analysis system,analyze injection molding mold flow and evaluate quality of injection molding.And based on the results of mold flow analysis,the mold structure design iscarried out.[Findings]It is informed that the melt flow state of the product is good,the fusion mark is less,and the air hole position distribution is reasonable.The maximum deformation of plastic parts is 0.2668 mm and the maximum shrinkage rate is 5.243%,which meets the technical requirements of the product.The mold adopts a two-plate structure of inlaying combined cavity.The lateral slider is used to pull the core and the multi-jacking rod is used to pull out the mold.[Conclusions]This method reduces the difficulty of mold manufacturing,which ensures the stability of demoulding.The mold structure produced by this method is simple,reasonable and reliable,which meets the requirements of remote control shell automation production.
