The invention belongs to the technical field of car door outer plates and provides a car door outer plate and a manufacturing method thereof.The car door outer plate comprises a supporting plate, a grid face and an appearance plate, and the middle of the supporting plate is hollowed out; the middle hollow part of the die-casting plate is fully paved with the grid surface; the supporting plate is installed on the inner side of the appearance plate through the injection molding technology. According to the outer plate manufactured through the method, the die-casting technology and the injection molding technology are adopted, firstly, the supporting plate and the grid face are machined through the metal die-casting technology, then the supporting plate and the grid face serve as embedded parts to be placed in an injection mold, and finally the supporting plate, the grid face and the appearance plate which are integrated are obtained through injection molding. Wherein the supporting plate and the grid surface can improve the concave resistance of the outer plate, and meanwhile, for the whole outer plate, the advantages that the weight is reduced, the working procedures are reduced, and the NVH performance is improved can be achieved; according to the method, injection molding is conducted through polyurethane, colored injection molding can be achieved, and the multiple advantages that the automobile door outer plate is light in weight, free of spraying, capable of improving the appearance quality and the like are achieved.

    本发明属于车门外板技术领域,提供了一种车门外板及其制作方法,包括支撑板、网格面和外观板,所述支撑板中部镂空;所述网格面铺满压铸板的中部镂空;所述支撑板通过注塑工艺安装在外观板内侧。本发明的方法制造的外板,采用压铸与注塑两种工艺,其首先通过金属压铸工艺加工支撑板和网格面,然后将支撑板和网格面作为嵌入件放置到注塑模具中,最后通过注塑得到一体的支撑板、网格面和外观板,其中支撑板和网格面可提高外板抗凹性能,同时对于整个外板来说可实现轻量化,减少工序,提升NVH性能等优点;本发明的方法通过采用聚氨酯进行注塑,可以做到带色注塑,有助于实现车门外板轻量化、免喷涂、提升外观质量等多重优点。
