IPC: B29C33/38
Filed: 1993-09-24
Abstract: PURPOSE:To enable a simple casting having a little pin hole and blow hole and excellent dimensional precision by heating the inner part of a casting chamber fixing a mold to near the m.p. of molten metal, reducing the pressure, pouring the molten metal in the mold and slowly cooling while controlling. CONSTITUTION:The molten metal 13 is heated to the temp. at higher than the m.p. and held to a crucible 14. After arranging the mold 3 and a base board 4 into the casting chamber 1 by a lifting device 5, the casting chamber 1 is heated to near the m.p. of the molten metal 13 and the pressure in the casting chamber 1 is reduced through a vacuum pump 2. Before starting the casting, the opening part 24 of an upper fixed plate 18 in a melting chamber 11 is opened and impurity in the molten metal 13 is removed. Then, a control rod 20 is moved upward with a motor 19 to open the pouring hole 15, and after pouring the molten metal 13 containing the impurity at the time of starting casting into a receiving pan 21 through a trough 22, the molten metal is cast into the mold 3. After completing the casting, the temp. control in the casting chamber 1 is executed so as to become a prescribed temp. gradient. When the cast metal becomes the prescribed temp., the control circuit is cut off and the natural cooling is executed. Further, the reduced pressure in the casting chamber 1 is released at the time when a specific temp. is attained.
