分析了车载电视外壳的结构特点和成型工艺;阐述了车载电视外壳模具的结构和工作过程.模具采用一模一腔,潜伏式推杆自切式浇口,斜推杆侧抽机构,并用Moldflow软件进行了最佳浇口位置分析,运用UG软件进行了整套模具的设计.实践证明,模具机构活动灵活,脱模顺利,塑件质量满足要求.
The mold structure and working process of car television shell were expounded according to the analysis of its structure characteristics and molding technology. The mold had features of one cavity per mould, submersible push rod cutting gate and side core-pulling mechanism of slanted ejector pin. The best gate location was analyzed by Moldflow software, and the whole set of mold was designed by UG software. Experience proved that the mold moved flexibly, the plastic parts demoulded smoothly and their quality met requirements well.
