The invention discloses a stretchable turnover mold for a fabricated building, and relates to the technical field of fabricated buildings. The mold comprises a movable center skeleton, at least threewall plates and a top plate, wherein the wall plates are arranged at the periphery of the movable center skeleton and are connected with the movable center skeleton, and the top plate is arranged at the upper end of the movable center skeleton and encloses a cavity with the wall plates; the movable center skeleton comprises a center base frame, at least three side supports and an upper support, and the side supports and the upper support are connected to the center base frame. The stretchable turnover mold for the fabricated building can generate the support mode with multiple plane sizes andmultiple heights, the mold stretchable turnover mold has the advantages that the structure is simple, the use is convenient, multiple turnover is achieved, the stretchable turnover mold is durable, materials are saved, and the economy is obviously improved.
