CENTRIFUGAL CASTING MACHINE FOR MANUFACTURING ROTOR

摘要

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.

1. A centrifugal casting machine, comprising:
a rotating plate which rotates by means of a rotational force generated by a motor; a sleeve installed on the rotating plate and having a cylindrical shape having an internal diameter corresponding to an external diameter of a plurality of silicon steel plates constituting a core and stacked in the sleeve; an upper mold internally installed on an upper end of the sleeve to define a first molding space between the upper mold and the core, in which a molten metal is introduced into the first molding space to mold an end ring; a lower mold internally installed on a lower end of the sleeve to define a second molding space between the lower mold and the core, in which a molten metal is introduced into the second molding space 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 an upper end of the core; and a hydraulic ram passing through the rotating plate and coupled to the lower mold, the hydraulic ram being moved up and down by a lifting device to move the lower mold up and down and being coupled to the rotating plate to rotate therewith.
