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.
Claims10
An injection mold for rotary-type gravity casting, comprising:
- a molten metal-supply chamber selectively coupled to a die and 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.
A gravity casting method using an injection mold for rotary-type gravity casting, the method comprising:
- displacing a die to cause an injection port of the die to face downward;
- supplying a molten metal into the injection mold having a molten metal-supply chamber configured to 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;
- moving the injection mold to pressure-fit with the die;
- and
- rotating the pressure-fitted injection mold and the die.
