A casting mold shaping apparatus is provided that includes: a pressing member for pressing charged casting sands in a molding space formed by a molding flask and a carrier plate placed on a squeezing table; a driving mechanism for performing driving so as to bring the pressing member and the squeezing table close to each other or separate that pressing member and the squeezing table from each other, the driving mechanism including an output unit that relatively moves along a direction of pressing the pressing member; an electric motor for driving the driving mechanism; and a pressure adjustment device for adjusting a force of the driving mechanism outputted to the output unit so as to decrease and causing the pressing member to generate a predetermined pressing force necessary for pressing the casting sands, are included.
