The invention discloses a double-curvature deep cavity skin active bulging wall thickness uniform control mold and method. According to the method, two-step forming is achieved through a set of forming die, in the first step, reverse bulging is utilized, a plate is attached to an upper die for material storage, and in the second step, a final part state is formed through a lower die. According to the structural characteristics of the part, a groove structure is arranged on the periphery of the maximum thinning area of the material storage part of the upper die, the upper die part corresponding to the maximum thinning area is not provided with the groove structure, and the groove characteristics are formed in the first step. In the second step, forward bulging is conducted, the part formed in the first step is attached to the lower die, the thickness reduction of the bottom area of the skin part is reduced through the material storage groove structure of the upper die, the wall thickness of the double-curvature deep-cavity skin part is more uniform, and meanwhile the orange peel phenomenon caused by the thickness reduction can be reduced.
