摘要
某汽车储物盒结构复杂、外观面不允许有进胶痕迹,为此设计了在外观面的背面进胶的倒装注塑模。该模具具有热流道浇注系统,定模液压缸推出机构,定模四面液压缸抽芯机构以及在大滑块内设计斜顶和在大滑块内设计小滑块的二次抽芯机构。经检验,所设计的模具结构合理,动作可靠,可以满足生产要求。
The car storage box has a complex structure, and there is no defect allowed on its appearance surface. For this reason, a flip injection mould was designed with a gate on the back of appearance surface. A hot runner system, a hydraulic cylinder ejecting mechanism, a four-sided hydraulic cylinder slide-pulling mechanism, and a two-step slide-pulling mechanism of lifter in large slide and little slide in larger slide on the fixed mould were designed. The results indicated that the structure of mould was reasonable and reliable and could meet the requirement for production.
