DIE CASTING DEVICE AND METHOD FOR AMORPHOUS ALLOY

摘要

A die casting apparatus (100) for amorphous alloy and a method of die casting amorphous alloy may be provided. The die casting apparatus may comprise a stationary die (1) and a movable die (2); a sealed cabin (4) defining 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 molten 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).

1. A method of die casting an amorphous alloy, comprising:
treating gas in a sealing chamber defined in a sealed cabin; supplying a protecting gas into the sealing chamber to maintain the protecting gas in the sealing chamber to a pressure higher than an environmental pressure; feeding amorphous alloy into a melting device disposed inside the sealing chamber to obtain the molten amorphous alloy while the protecting gas filled within the sealing chamber overflowing outside; feeding the molten amorphous alloy into a die chamber defined by a mated stationary die and a movable die via a feed sleeve with a plunger positioned therein; and opening the mated stationary and movable dies to extract at least a component formed at least partially of the amorphous alloy from inside the die chamber while the protecting gas filled within the sealing chamber overflowing outside.
