Abstract
A molding system to make a sand mold with a frame is provided to receive the lateral loads generated when molding frames are fed out and in by nearby apparatuses and to prevent vibrations generated during a molding operation from being transmitted to nearby apparatuses, so that the area around a factory is prevented from being degraded and so that apparatuses can be easily affixed. The molding system includes a molding support located on a plurality of vibration-insulating pads, a turntable to allow pattern carriers to be alternately fed in and out above the molding support, a molding head that is located above the turntable and that moves up and down, two pairs of centering pins located on the molding head, roller frames for feeding in and out molding frames from which hang rollers located outside of and near the highest end of the molding head, centering bushes, located above the roller frames for feeding molding frames in and out, that correspond to the two pairs of the centering pins, and a roller hung from the molding head.
