Abstract: A manipulator for use in effecting separation of split coated permanent moulds and for cleaning air injection holes in one of the mould parts. The manipulator comprises a frame with a hoist mechanism accommodated in its bottomm portion to lift the metal moulds in position for separation. Clamping device and a turnover device are mounted on the frame above the hoist mechanism. The frame also carries a broaching mechanism mounted above the clamping devices adapted to push out a casting from one part of the mould into another one while concurrently removing the used coating from the air injection holes.

Abstract: An automatic line comprises, arranged in series in accordance with the casting flowsheet and interconnected by conveyer means: a unit for applying a coating to the working face of the metal mould parts; a unit for assembling metal moulds from the coated parts thereof; a unit for pouring molten metal into the assembled mould; a unit for solidifying the casting inside the mould; a unit for disassembling the mould and removing the casting therefrom; a unit for cleaning the mould parts off the used coating; a unit for stabilizing the temperature of the cleaned mould parts prior to a re-coating cycle.
