Universal base precast concrete stair vertical mold

The invention discloses a universal base precast concrete stair vertical mold, and relates to the technical field of precast concrete member production and manufacturing, the universal base precast concrete stair vertical mold comprises a double-layer frame, a base mold, a stair upper mold and a stair lower mold, and the lower side of the base mold is fixedly connected with the upper side of the double-layer frame. The rotating rod is clamped by the bevel rod to roll in the groove of the inner groove plate, the groove in the inner groove plate is in the shape of an inverted rounded sector, when the rotating rod rolls in the arc length area of the groove of the inner groove plate, the curvature is gentle, the rotating rod rolls rapidly, the sliding rod swings at a certain angle, the knocking ball knocks the stair upper mold for multiple times, and the working efficiency is improved. Through the arrangement of the knocking assembly, the two ends of the stair upper mold are knocked and vibrated ...
