The invention discloses a heating casting device for casting a large rotor iron core. The heating casting device comprises a heating device for heating the rotor iron core, and is characterized by further comprising a plug ejection device. A casting mold is further provided with a mold heating tool used for heating the casting mold. A ladder is further mounted on a casting rack. A rotating mechanism is arranged on a heating mechanism, so that a rotor keeps rotating at a constant speed during heating, the overall heating temperature of the rotor is more uniform, and the heating efficiency is high; through the arrangement of a high-frequency heating mechanism, a plug on the rotor is heated through the high-frequency heating mechanism after the rotor is heated, and the situation that the temperature of the plug is insufficient is avoided; and through the arrangement of the mold heating tool, the mold is heated in advance, so that the liquidity of molten aluminum is improved, the rotor casting is fuller, the prod
