Abstract
The present invention is to provide a vertical casting apparatus capable of easily manufacturing castings without causing shrinkage cavities and entrainment of gas, by filling a molten metal into a mold cavity at a high speed and by effectively pressurizing the molten metal in the closed cavity, which has high work efficiency, ease of maintenance, and a low cost of equipment, and a vertical casting method using the vertical casting apparatus. The vertical casting apparatus is provided with an apparatus body comprising a fixed mold 1 on the lower side and a movable mold 2 on the upper side, a closing means 13 for closing a molten metal in-flow gate 10 formed in the fixed mold 1, and a pressurizing means 20 for pressurizing the molten metal in the closed mold cavity, and a casting means for supplying and filling the molten metal into the mold cavity from the underside. The casting means has a gas-pressurized molten metal pouring ladle 6 attachable to and detachable from the apparatus body.
