Title: VERTICAL CASTING APPARATUS AND VERTICAL CASTING METHOD
Abstract:
A vertical casting apparatus capable of easily manufacturing castings without causing shrinkage cavities and entrainment of gas by filling a molten metal in a mold cavity at a high speed and effectively pressurizing the molten metal in the closed cavity, having excellent working efficiency, and enabling the easy maintenance and a reduction in facility cost and a vertical casting method using the vertical casting apparatus. The vertical casting apparatus comprises an apparatus body having a lower side fixed mold (1) and an upper side movable mold (2), a closing means (13) closing a molten metal in-flow gate (10) formed in the fixed mold (1), and a pressurizing means (20) pressurizing the molten metal in the closed mold cavity which can form the mold cavity and a casting means supplying and filling the molten metal into the mold cavity from the underside. The casting means further comprises a gas-pressurized molten metal pouring ladle (6) attachable to and detachable from the apparatus body.
