Laminated mold

The invention discloses a laminated mold which comprises a fixed mold, a worm, positioning rods, a driving bevel gear and sub-cavities, an outer gear is fixedly installed on the outer side of the fixed mold, racks are arranged on the upper side and the lower side of the outer gear, the worm is fixedly installed in the fixed mold, worm wheels are installed on the front side of the worm, the positioning rods are installed at the four corners of the fixed mold, movable molds are fixedly mounted at the top ends of the positioning rods, the driving bevel gear is fixedly mounted on the inner side of a driven flat gear, and the sub-cavities are mounted on the surfaces of the inner sides of the movable molds. According to the laminated mold, the novel structural design is adopted, a gear and rack combination is installed on the outer side of the mold, the racks are driven to move synchronously through rotation of the gear, due to the fact that the specifications of the gear and the racks are kept unchanged, the condi
