1457845 Foundry moulding KHARKOV FILIAL VSES NI INST LITEJ MASHINOSTRO LITEI TEKHNOLOGII I AVTOMATIZATSII LITEI PROIZVODSTVA 27 Aug 1974 37457/74 Heading B3G A device for placing cores 1 into flaskless moulds 2 and for transferring the cored moulds from their flasks into abutment with a row of similar moulds, includes a Fig. 8, with one or more core receiving seats 9, movably mounted within a hollow body 4 connected by a hinge 15 to a flange 14 secured to the piston-rod 13 of a stationary cylinder 11. With the device in its fully retracted position, Fig. 1, a roller 16 of a stationary stop 17 enters an aperture 19 in the body 4 and causes the body to tilt, in which position the jig receives one or more cores. The rod 13 is then driven outwardly and the cores located in seats 2b in the mould 2; the front of the jig first contacts the mould, and on further movement of the body 4, the mould is engaged by the body and forced from its moulding chamber and flask into abutment with the mould row. Such further movement is effected against the action of pushers 10, one for each core, each pusher comprising a sleeve 21 slidable on a pin 20 and urged outwardly by a spring 22.
