Centrifugal casting device for manufacturing rotor

摘要

The present invention relates to a centrifugal casting apparatus for manufacturing a rotor. The purpose of the present invention is to provide the centrifugal casting apparatus for manufacturing a rotor capable of preventing a gap between silicon steel plates constituting a core from being widened as a hydraulic ram applies a constant pressure to a lower mold when a rotor is centrifugally casted by vertically moving the lower mold arranged to be located in the lower part of the core by the hydraulic ram. To achieve the objective of the present invention, the centrifugal casting apparatus for manufacturing a rotor comprises: a rotary plate rotating by receiving a rotational force generated in a motor; a sleeve installed in the upper part of the rotary plate, wherein a plurality of silicon steel plates are stacked inside as being formed to have a cylindrical structure with an inner diameter corresponding to an outer diameter of a silicon steel plate constituting a core; an upper mold installed in the upper end inside the sleeve to form a space into which molten metal for molding of an end ring in the upper part of the core is injected; a lower mold installed in the lower end inside the sleeve to form a space into which molten metal for molding of an end ring in the lower part of the core is injected; a dummy shaft inserted into the center of the core, and combined with the lower mold; a cap assembled with the upper end of the dummy shaft to press the upper end of the core; and a hydraulic ram combined with the lower mold through the rotary plate, to vertically move the lower mold while vertically moving by driving a lifting device, and combined with the rotary plate so as to rotate with the rotary plate.
