ANLAEG TIL FREMSTILLING AF SAMMENSATTE STOEBEEMNER

Installation for producing composite castings 67 e.g. squirrel cage rotors for electric motors by casting round prefabricated inserts 7 in the casting mould 4, 5 of a pressure casting or injection moulding machine 1. Ancillary devices for feeding the inserts e.g. stacks of laminations 7 to the mould and removing the composite castings 67 from the mould, spraying the moulds with a release agent and stripping the composite castings 67 from the sprue system are provided. In order to increase the productivity of the casting installation, an ancillary device disposed between a feeder-discharge device 24 to 30 and a station for the prefabrication of the inserts 7 located outside the installation, has an automatic separating-transfer station 13, 16, in conveying relationship 10, 12, with the insert prefabrication station. The feeder- discharge device 24 to 30 is further equipped with multiple gripper tongs 24, 26 each for loading and unloading the inserts 7 and composite castings 67 respectively. The multiple gripper tongs are pivoted together into position between the open casting mould sections 4, 5 and removed from there in synchronism with the mould sprayer device 6.
