摘要
介绍了基于汽车尾门装饰外板的注射模实用结构,并论述了模具工作过程。该模具采用针阀式热流道转冷流道大水口搭接式洗口与斜顶式潜伏洗口组合进股,一模一腔,卧式注射成型,电镀加涂装的塑件表面处理工艺;运用UG/CA D完成了塑件分型面设计,创新设计了由顶杆、直顶、斜顶及片状排气镶件组合而成的模具结构特征;借助MoldFlow2019,创建了管道循环冷却系统,并对塑件填充时间、冷却效果及翘曲变形量进行模拟分析,得到了合理的注射成型参数指导模具实际生产。
A practical structure was introduced on the injection mold for Automobile exterior trim panel for tailgate and the working process is discussed.This mold uses valve hot runner to cold runner overlap gate and lifter type submarine gate,one mold cavities,horizontal injection molding,the surface treatment technology of products with plating and coating.Using the NX/CAD completed the mold parting surface design,the innovative design by the ejector pin,ejector block,lifter and flaky exhaust inserts of the mold structure characteristics.With the help of MoldFlow2019,the pipeline circulation cooling system was created,and the filling time,cooling effect and warping deformation of plastic parts were simulated and analyzed,and reasonable injection molding parameters were obtained to guide the actual production of molds.
