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.

主权项

1. A sand casting mold production system filling sand in a frame in which a pattern is arranged so as to produce a sand casting mold, said sand casting mold production system comprising:
a sand feed nozzle feeding said sand into said frame; a nozzle movement device which is configured to make said sand feed nozzle move; and a control device controlling said nozzle movement device, wherein said frame is a hollow member having an open top surface part and positioned in a coordinate system of said nozzle movement device, said control device comprises a sand feed position defining part virtually dividing an open region of said top surface part of said frame into a plurality of sub regions and defining coordinates of said individual sub regions as sand feed positions on the coordinate system of said nozzle movement device, a height measuring part measuring a height of an internal space of said frame at the individual sand feed positions, and a sand feed determining part determining an amount of sand to feed at said individual sand feed positions based on said height at said individual sand feed positions, and said control device makes said nozzle movement device operate so as to successively position said sand feed nozzle at the individual sand feed positions and feeds the amount of sand determined by said sand feed determining part to each said sand feed position from said sand feed nozzle to the inside of said frame.
