  • Centrifugal casting machine for manufacturing rotor
    Patent number: 9364892
    Abstract: Disclosed herein is a centrifugal casting machine, including: a rotating plate rotating by means of a motor; a cylindrical sleeve installed on the rotating plate and having an internal diameter corresponding to an external diameter of silicon steel plates constituting a core in the sleeve; an upper mold internally installed on the sleeve to define a first molding space into which a molten metal is introduced to mold an end ring; a lower mold internally installed on the sleeve to define a second molding space into which a molten metal is introduced to mold an end ring; a dummy shaft fitted in the center of the core and coupled to the lower mold; a cap coupled to an upper end of the dummy shaft to press the core; and a hydraulic ram coupled to the lower mold to move the lower mold up and down and coupled to the rotating plate to rotate therewith.
