The invention discloses a device facilitating mold stripping for a fabricated building. The device comprises a mounting table, a bearing plate, a vertical mold stripping device, a transverse mold stripping device, a through frame, a rotating motor and an anti-sticking plate, wherein a mounting groove is formed in the bottom of the mounting table in a penetrating mode, and the top end of the bearing plate is fixedly connected with the bottom of a hydraulic cylinder. The device facilitating mold stripping for the fabricated building is provided with movable wheels, the mounting table is pushed to drive the movable wheels to move so as to move an overall prefabricated part mold outdoors for prefabricated part pouring treatment, thus, the circumstance that the overall prefabricated part mold is fixed at the same position for a long time, so that the overall drying period is long and the drying efficiency is low after the prefabricated part is poured is avoided, meanwhile, through external air drying and sunlight irradiation, the drying period of the prefabricated part is shortened, the drying efficiency of the prefabricated part mold is improved, and the production efficiency of the prefabricated part is sequentially improved.
