Abstract
An injection mold for rotary-type gravity casting and a gravity casting method using the same are provided. The injection mold includes a molten metal-supply chamber that is selectively coupled to a die. The molten metal-supply chamber is also configured to, during gravity casting along with rotation, supply a pure molten metal into the die while collecting impurities contained in the molten metal and preventing the ingress of the impurities into the die.
