Abstract

763,036. Moulding-machines. HANSBERG, F. Aug. 27, 1954 [Feb. 16, 1954], No. 24976/54. Class 83 (1). [Also in Group XXX] A machine for filling foundry core-, or mouldboxes comprises an annular rotary or axiallymovable slide-valve 19 surrounding a sand storage-container 10. The valve 19 carries a double-acting piston 25, 26 both sides of which are normally in communication with a com-- pressed-air chamber 3. When a valve 27 is operated to cut off the air supply to the larger piston 26, air passes between the valve and its seating 29 through slots 13 and blows the sand into a core-box. Air also enters through slots 11 in the container 10 to reduce friction. The container is refilled from a tray 17 by opening a shutter 16 controlled by the valve 27. The latter valve also controls movement of the core-box table to and from the nozzle 7. Air and excess sand forced out from the box enter a hood 9 provided with exhaust passages. The flow of compressed air to the chamber 3 may be regulated to shorten or prolong the period of ejection. The valve may be spring-loaded in one direction of movement. Specification 672,487 is referred to.
