The invention belongs to the technical field of die casting, and provides a high-pressure casting car door inner plate structure which comprises a car door body, the car door body is formed by integrally die-casting a window frame part and a lower half part, a window frame column is arranged on the window frame part, and reinforcing ribs used for drainage in the die-casting filling process are arranged on the inner side of the window frame column. The aluminum alloy window frame has the advantages that when the aluminum liquid is filled through the reinforcing ribs, the aluminum liquid is guided to smoothly flow towards the upper portion of the window frame, the whole window frame is finally filled, the shallow crossed reinforcing ribs are increased, the solidification stress of the aluminum liquid is dispersed, the projection area of parts can be effectively reduced, and therefore the requirement for equipment tonnage is reduced, and the production cost is reduced.

    本发明属于压铸技术领域,提供了一种高压铸造车门内板结构,包括车门体,车门体为窗框部分和下半部分一体压铸成型而成,窗框部分上具有窗框柱,在窗框柱的内侧上设置有在压铸填充过程中用于引流的加强筋。本发明的优点在于利用加强筋在铝液填充过来时,引导铝液顺利的向窗框上部流动,最终填充满整个窗框,增加浅的交叉的加强筋,分散铝液凝固应力,可以有效减少零件的投影面积,从而减小对设备吨位的需求,降低生产成本。
