PROBLEM TO BE SOLVED: To provide a rotor core casting device and a rotor core casting method capable of reducing deformation of the laminated steel plate of a rotor core, incident to thermal contraction of a ring-shaped casting section.SOLUTION: A rotor core casting device includes a casting mold for casting a rotor core by internally arranging a cylindrical laminated steel plate laminating a plurality of circular steel plates, pouring molten metal and cast-in inserting the laminated steel plate, and including a ring-shaped runner where molten metal flows, and a cast-in inserting member arranged removably on the internal diameter side of the ring-shaped runner of the mold, and taken out together with the rotor core when taking out the rotor core from the inside of the mold, and then removed from the rotor core. |
