The invention belongs to the technical field of plastic tail doors, and provides a water-assisted molded plastic tail door inner plate mounting structure which comprises a tail door inner plate, a tail door outer plate, a spoiler and a rear windshield, wherein the spoiler is connected with the outer plate and the inner plate to form a tail door body, a window frame part is formed on the tail door inner plate, the rear windshield is connected to the window frame part on the tail door body, closed cavity channels are formed in the positions, which are close to the upper boundary and the lower boundary of the rear windshield, of the two sides of the window frame part of the tail door inner plate in a water-assisted mode. The mounting structure has the advantages that the closed cavities are formed in the window frame areas on 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 cancellation of the metal reinforcing plate brings a better light-weight effect.
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结构,包括尾门内板、尾门外板、扰流板以及后风挡,扰流板与外板与内板连接后形成尾门本体,尾门内板形成有窗框部,后风挡连接在尾门本体上窗框部上,尾门内板的窗框部两侧在后风挡的上下边界的附近位置水辅成型有封闭腔体通道。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。
