SAND CASTING MOLD PRODUCTION SYSTEM AND SAND CASTING MOLD PRODUCTION METHOD FOR PRODUCING SAND CASTING MOLD

摘要

A sand casting mold production system provided with a nozzle movement device and a control device for the same. The control device is provided with a sand feed position defining part virtually dividing an open region of a top surface part of a frame into a plurality of sub regions and defining coordinates of the individual sub region as sand feed positions on the coordinate system of the nozzle movement device, a height measuring part measuring the height of an internal space of the frame at the individual sand feed positions, and a sand feed determining part using the heights at the individual sand feed positions as the basis to determine the amounts of sand to be fed at the individual sand feed positions. Further, the determined amount of sand is fed to each sand feed position from the sand feed nozzle to the inside of the frame.
