Abstract
PURPOSE: To obtain the captioned device capable of preventing leak of sand completely when blowing, by providing a shutter of specified mechanism between a hopper and a blow head elevetably suspended in the lower part thereof, and linking a guide tube slidably inserting into the blow head.
CONSTITUTION: When an opening part 10' of a shutter 10 is caused to slide up to the position of a flange tube 7 by operation of pneumatic cylinder 11, sand drops, and is collected in a blow head 1 through a guide tube 4, while forming an angle of repose α. When flowing of sand stops, the cylinder is operated automatically to close the shutter, and pressurizing air is applied to U-shaped seal packing 9 to press the shutter, thereby sealing the blow head airtightly. Then, an elevating cylinder 22 operates to lower the blow head, and a plate 2 is press-fitted to the upper surface of a die 25. When compressed air is injected from a suction pipe 23 through a filter 19, sand is press-fed into the die through a nozzle 24.
