Abstract
A method for moving an upper mold against a lower mold in a mold casting machine having a mold clamping mechanism attached to a lifting and lowering frame. The mechanism has an upper mold lifting and lowering device that assembles and separates the upper and lower molds by lifting and lowering the upper mold relative to the lower mold and the frame. A space for a setting a core and for taking out products is formed between the upper and lower molds by lifting the device relative to the frame, and by lifting the frame relative to the lower mold. Then the frame is lowered until the upper mold comes close to the lower mold. Thereafter the upper mold is lowered by the device to form an assembled mold, molten metal is introduced into the mold and after the metal has solidified the upper mold is lifted by the device, all while the frame is kept fixed relative to the lower mold.
