Abstract
A molding machine for fabricating boxless molds wherein the mold boxes or flasks for the mold halves are moved, upon arms of a turnstile or rotatable cross-shaped element, cyclically to various molding stations of the molding machine. Fabrication of a casting mold at the closing or assembly station is rendered possible in that, a support plate of a conveyor device for the further transport of the casting molds is structured as part of the closing or assembly station. An ejector punch, a support means for the mold boxes or flasks and an elevationally displaceable table are arranged such that a mold lower part and a mold upper part are successively ejected into the support plate for the purpose of forming the casting mold.
