The utility model relates to an automobile chassis cross beam internal high pressure preforming and internal high pressure common die structure which comprises a lower die bottom plate and an upper die bottom plate, a lower die preforming cavity is fixed on the front side of the middle of the lower die bottom plate, a lower die seat is fixed on the rear side of the middle of the lower die bottom plate, a lower die cavity is fixed on the lower die seat, and a lower die is fixed on the lower die cavity. An upper die pre-forming cavity is fixed to the front side of the middle of the upper die bottom plate, an upper die base is fixed to the rear side of the middle of the upper die bottom plate, and an upper die cavity is fixed to the bottom of the upper die base. A preforming and internal high-pressure forming common mold structure is adopted, so that the problems that in the prior art, an internal high-pressure forming product is complex in mold structure and can only be manufactured through multiple devices are
