Integral drawing type tunnel boring machine (TBM) inverted arch block core mold

The invention belongs to the technical field of tunnel construction, and particularly relates to an integral drawing type TBM inverted arch block core mold which comprises an inverted arch block core mold body. The bottom surface of the inverted arch block core mold is fixedly connected with a bottom mold; first sliding grooves are formed in the positions, located at the four corners, of the top face of the bottom film in a penetrating mode. Positioning rods are slidably connected into the multiple first sliding grooves. A pair of second sliding grooves is formed in the opposite positions, below the bottom film, of the side wall of the positioning rod. An extrusion rod is slidably connected into the second sliding groove. According to the inverted arch block core mold, the positions are determined in advance through the multiple sets of positioning rods, the inverted arch block core mold can be conveniently installed and placed subsequently, meanwhile, the connecting mode of bolts and buckles is omitted, the
