Centrifugal casting machine for manufacturing rotor

Disclosed herein is a centrifugal casting machine for manufauctirng a rotor, wherein a lower mold arranged at the lower part of an iron core is driven to move up and down by a hydraulic push rod. In this way, the hydraulic push rod applies a certain pressure on the lower mold, so that no gap is generated among the silicon steel plates of the iron core. The centrifugal casting machine for manufauctirng the rotor is characterized by comprising 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.
