CASTING SAND BLOWING DEVICE FOR MOLDING MACHINES

摘要

A casting sand blowing device for molding machines, which has an odor gas processing device which causes less loss of compressed air pressure, which allows easy change of the mold blowing position, and which is small-sized and inexpensive. The casting sand blowing device comprises a sand storage tank having a sand spout nozzle and an exhaust valve, a compressed air storage tank having a compressed air discharge port, and a compressed air discharge port opening/closing means. A mold blowing position setting device comprises a fixing member for fixing a fixed-side mold piece and a slide member for sliding a movable- side mold piece. The odor gas processing device comprises a hood surrounding a shell machine, odor gas processing means, an odor gas suction mechanism, and an odor gas guide pipe.
