The invention belongs to the technical field of plastic tail doors, and provides a water-assisted molded plastic tail door inner plate which is mounted among a tail door spoiler area, a window frame area of a tail door and an outer plate area of the tail door, the tail door inner plate is provided with a window frame matching part, and closed cavity channel structures are formed at the two sides of the window frame matching part through water-assisted molding. The water-assisted molded plastic tail door inner plate has the advantages that closed cavities are formed in the window frame areas at the two sides of the tail door inner plate through a water-assisted forming method, so that the rigidity and strength of the areas are greatly enhanced, the inner plate is integrally formed, a metal reinforcing plate does not need to be additionally arranged to be connected with the inner plate body, the number of parts is reduced, procedures are simplified, and meanwhile, the metal reinforcing plate is omitted, so that a better light-weight effect is achieved.
本发明属于塑料尾门技术领域,提供了一种水辅成型的塑料尾门内板,安装在尾门扰流板区域、尾门的窗框区域和尾门的外板区域之间,该尾门内板具有窗框配合部,窗框配合部的两侧通过水辅成型形成有封闭腔体通道结构。本发明的优点在于通过水辅成型的方法在尾门内板两侧窗框区域形成封闭腔体,这样较大的增强了此区域的刚性与强度,内板一体成型,无需增加金属加强板与内板本体进行连接,减少零部件数量及简化工序,同时取消金属加强板会带来更好的轻量化效果。
