The invention discloses a stair pouring integrated forming mold, relates to the technical field of stair molds, and solves the problems that when an existing mold is used for pouring an integrated forming stair, the height and the width of stair steps cannot be correspondingly adjusted according to different stair sizes, so that the mold is high in use cost and cannot be repeatedly used. The stair pouring integrated forming mold comprises an upper mold base, a lower mold base is installed on the lower end face of the upper mold base, step synchronous distance adjusting mechanisms are installed on the two sides of the lower mold base, and a plurality of step shaping molds are installed on the inner side of the lower mold base; the stepping synchronous distance adjusting mechanism comprises a transmission motor, and an output shaft is arranged at the bottom end of the transmission motor. The width and the height of the stair steps are correspondingly adjusted according to the size of the ...
