Combined mold for producing concrete module prefabricated part

The invention relates to the technical field of concrete production, aims to solve the problem that an existing steel bar frame is prone to deviation in the vibrating process due to the fact that firm connection between the steel bar frame and a formwork is lacked, and particularly discloses a combined mold for concrete module prefabricated part production. A reinforcing steel bar frame is placed in the concrete mold, a part of the formwork pieces are slidably connected with a plurality of sets of clamping columns, each set comprises the clamping columns which are symmetrically distributed, the clamping columns are slidably connected with limiting clamping blocks, fixing clamps are placed on the clamping columns, one fixing clamp in the same set is fixedly connected with a concrete column, and the other fixing clamp in the same set is fixedly connected with the concrete column. And an extrusion column is slidably connected into the clamping column. By controlling the matching state of the limiting clamping bl
