Abstract

1457436 Moulds CATERPILLAR TRACTOR CO 17 Dec 1973 [22 Dec 1972] 58291/73 Heading B3F A mould having upper and lower portions 12 and 13 defining a casting cavity 24 and a feeder head cavity 22, is provided with a device 10 interposed between the cavities 24 and 22 and having an aperture 46 for regulating the flow of metal from the cavity 22 into the cavity 24. The device 10 comprises a frangible ceramic plate member provided with a thickened ribbed peripheral portion (48) which is located in a recess 43 in the mould. The metal is poured into the casting cavity 24 via downsprue 17, runner 18 and the cavity 22, and after solidification of the metal the mould is placed on a mechanical shaker to remove the mould sand from the metal and to cause the feeder head and the device 10 to break away from the casting formed in the cavity 24.
