Abstract
861,635. Casting composite articles. SCHAEFER, E. J. Sept. 22, 1958, No. 30196/58. Class 83 (1). A method of making a casting in a mould comprises sliding a flexible sleeve 35 over two co-operating mould members 21, 23, drawing the sleeve tightly against the members, removing a seal 53 from an opening in the sleeve, and introducing metal therethrough. A stack of laminations 10 to form the rotor of a squirrelcage induction motor has a series of grooves 11 which are filled with aluminium by the method, the rotor also being provided simultaneously with cast annular portions 13. Initially, the upper and lower mould parts 21, 23, and the laminations are clamped together by a bolt 25 and placed on a base 30, 20, having a metal inlet 33. A vacuum is applied by a connection 47 between a casing 43 and the silicone-rubber sleeve 35 to expand the sleeve, which can then be slid over the mould parts and secured by clamps 52. Vacuum is then applied to a connection 51, and air pressure to the connection 47, to force the sleeve against the mould parts. When a chain 54 is pulled, to release a siliconerubber seal 53, metal flows into the mould. A series of bases 20 may be carried by a conveyer for automatic operation. The seal 53 may be replaced by a disc of the metal to be cast, so that it fuses when the inlet 33 is submerged.
