Abstract

1328306 Foundry moulding machines SPO Inc 19 July 1971 [20 July 1970] 33796/71 Heading B3F A foundry moulding machine comprises a pressure head 3 and a flask-carrier 8 relatively movable towards and away from each other along a vertical axis to compress sand 10 in a flask 7 by means of retractable peen feet 6 mounted by peen pistons 5 in a cylinder manifold 11 attached to the pressure head 3. Before sand compression hydraulic fluid 19 from a reservoir 17 is supplied to the cylinder manifold through a check valve 14 to move the peen feet 6 to their lowermost positions. During pressing the peen feet enter the sand 10 to different heights in the flask 7 and compress the sand uniformly as the hydraulic fluid in the cylinder manifold cannot escape through check valve 14. At a preset maximum pressure the hydraulic fluid in the cylinder manifold 11 is released by a return valve 15.
