Connecting structure of combined core mold

The utility model discloses a connecting structure of a combined core mold. The connecting structure of the combined core mold mainly solves the technical problems that when an existing combined core mold is assembled, connection is difficult, and firmness and sealing can not be achieved. According to the technical scheme, axially-through grooves (2) where filling materials (3) are injected or strip-shaped plates are embedded are formed in the two ends of each mold shoe (1), the mold shoes (1) are connected and sealed through the axially-through grooves (2) formed in the two ends of the mold shoes (1), the filling materials (3) are injected in the grooves (2), and mortises and tenons are formed after the filling materials (3) are cured, so that the two mold shoes are fixedly connected; or the strip-shaped plates are embedded in the grooves (2) to fixedly connect the two mold shoes (1). The connecting structure is mainly used for connecting and sealing of the combined core mold.
