Abstract
898,797. Moulding-machines. INDUSTRIAL FOUNDRY MATERIALS Ltd., and WILLIAMS Ltd., H. H. June 13, 1960 [March 12, 1959], No. 8578/59. Class 83 (1). In a shell-moulding machine of the kind described in Specification 880,853 which is referred to, the core-box is carried on a pivoted frame 8 so that the box does not contact the container 30 during its travel to and from the outlet 29, the box being clamped to the outlet when thereabove by a piston 27. The movable core-box half 19 is supported on a crosshead 18 movable by the piston 17 of a cylinder 16 to close the box. The cylinder 16 is itself carried by a crosshead 15 which is movable by the piston 14 of a cylinder 13 to position the box over the outlet 29 of the mix container 30. Two machines may co-operate with one mix container. The movable core-box support 18 incorporates an ejector plate 22 with pins 23 and resetting pins 25. The automatic control circuit for the machine is air operated.
