本发明提供了一种大丝束连续碳纤增强汽车地板VARTM成型模具，包括上模、下模和由上模和下模闭合后形成的模腔，所述模腔连通有进胶管路和抽真空管路，所述抽真空管路连通压力缓冲罐，所述压力缓冲罐的出口端通过压力控制器和第一阀门外接第一抽真空支管。该成型模具设计压力控制器和压力缓冲罐，用压力缓冲罐来平衡压力控制器调节压力的过程中所引起的压力快速、大幅度波动的问题，从而使大丝束纤维浸润均匀、充分且浸润效率高、质量好。

The invention provides a large tow continuous carbon fiber reinforced automobile floor VARTM forming die, which comprises an upper die, a lower die and a die cavity formed after the upper die and the lower die are closed. The die cavity is connected with a glue inlet pipeline and a vacuum pumping pipeline, and the vacuum pumping pipeline is connected with a pressure buffer tank, The outlet end of the pressure buffer tank is externally connected with a first vacuum pumping branch pipe through a pressure controller and a first valve. The forming die is designed with a pressure controller and a pressure buffer tank. The pressure buffer tank is used to balance the problem of rapid and large-scale pressure fluctuation caused by the pressure controller in the process of adjusting the pressure, so as to make the large tow fiber infiltrate evenly and fully, with high infiltrating efficiency and good quality.
