Abstract: Proposed are an apparatus for molding a material, and a method for molding a material by using the apparatus. The apparatus includes first and second fixed platens (110 and 120) provided as a pair and spaced a predetermined distance from each other by tie bars (150), a movable platen (140) movable along the tie bars (150) between the first and second fixed platens (110 and 120), a mold (200) which is provided with a movable mold (220) and a fixed mold (240) and which forms a molding space (260) that is capable of being open or closed as the movable mold (220) moves in a direction toward or away from the fixed mold (240), and a pressing block (300) selectively positioned between the first fixed platen (110) and the movable mold (220) such that the pressing block is capable of applying a pressure to the movable mold (220).

Abstract: An apparatus and method for melting and forming metal in a vacuum environment. Metal is melted within a metal-forming apparatus and the molten metal is filled into a mold cavity. A high-level vacuum environment is created in the apparatus by drawing air from the apparatus which is sealed from atmospheric air. This makes it possible to reduce contact with air, which can improve the quality of the metal product.

Abstract: A mold device for forming metal in a high-level vacuum environment. The mold device comprises a fixed mold, a movable mold adjoining the upper portion of the fixed mold to form a mold cavity, a closing plate placed closely on top of the movable mold, and an ejector pin extending through the closing plate and the movable mold into the mold cavity. Packing is disposed in a hole in the closing plate through which the ejector pin extends, thereby preventing atmospheric air from entering the mold cavity. There is a blocking space between the movable mold and the packing to prevent heat from being transferred to the packing. An exhaust unit creates a vacuum environment by drawing air from the mold cavity. The metal product is pushed out by the ejector pin.
