The invention provides a multiple-formwork assembled type building mold. The multiple-formwork assembled type building mold comprises a mold body; four fixed rods are welded to the bottom of the innerwall of the mold body, and four third fixed plates are welded to one ends of the fixed rods; the top of the mold body is provided with a groove opening, the groove opening is internally provided witha slide groove, and a working shell is slidably connected to the interior of the slide groove; and the bottom of the working shell is placed on the surfaces of the tops of the third fixed plates. Inconclusion, through the multiple-formwork assembled type building mold, the dimension precision of a building component is improved, operators can take the formed building component conveniently, andthe forming rate of the building component, the percent of pass of the building component and the benefits of an enterprise are increased.
