Abstract (en)
[origin: WO2013086990A1] A die casting apparatus (100) for amorphous alloy comprises a stationary die (1) and a movable die (2); a sealed cabin (4) difining a sealing chamber (40); a protecting gas supplying device connected with the sealed cabin (4) for supplying the protecting gas into the sealing chamber (40); a melting device (5) for receiving and melting amorphous alloy; a feed sleeve (6) having a molten material inlet (60), with a plunger (7) positioned therein for injecting the molted amorphous alloy from the melting device (5) into a die chamber via the molten material inlet (60); a driving device (8) connected with the plunger (7) for driving the plunger (7) in the feed sleeve (6); and a gas purifying device (10) communicated with the sealed cabin (4) for purifying the gas from the sealed cabin (4). A method of die casting an amorphous alloy comprises the steps of purifying a sealing chamber (40) defined in a sealed cabin (4); supplying protecting gas into the sealing chamber (40) to maintain the protecting gas in the sealing chamber (40) to a positive pressure; feeding amorphous alloy into a melting device (5) to obtain the molten amorphous alloy; feeding the molten amorphous alloy into a die chamber (3); and opening the mated stationary and movable dies to extract at least a component. The apparatus and method use positive pressure protecting gas without the need to form high degree vacuum, thus reducing manufacturing and maintenance costs.
