Casting and molding equipment and method of manufacturing amorphous alloy structural unit

A casting and molding equipment for producing an amorphous alloy structural unit, the equipment comprising:

• an injection system;
• an alloy melting system;
• a material feeding system;
• a mold system;
• a vacuum system;
• and
• a protective gas supply system;
• wherein:
• the injection system comprises an injection tube, an injection mechanism, and a plunger rod;
• the plunger rod is adapted to move along an inner wall of the injection tube, and the injection mechanism is configured to control a moving direction and moving speed of the plunger rod;
• the alloy melting system comprises a melting chamber and a heating unit;
• the heating unit is configured to melt an alloy material in the melting chamber;
• the heating unit comprises an induction coil or resistance wire;
• the melting chamber is disposed in the injection tube, and the heating unit is disposed out of the injection tube;
• the material feeding system comprises a material tank and a transition chamber;
• the alloy material is stored in the material tank;
• the transition chamber is a tubular structure having two open ends;
• the plunger rod is adapted to slide in the transition chamber;
• the material tank is disposed on the transition chamber and communicates with the transition chamber;
• the mold system comprises a fixed die, a seal ring, a moving die, a die cavity, an exhaust channel, a constant pressure one-way valve, a pouring channel, and a mold opening and closing mechanism;
• the mold opening and closing mechanism is configured to control the opening and closing of the fixed die and the moving die;
• the closing of the fixed die and the moving die generates the die cavity;
• the die cavity communicates with the injection tube via the pouring channel;
• the die cavity communicates with external environment via the exhaust channel;
• the constant pressure one-way valve is disposed at one end of the exhaust channel;
• and the fixed die and the moving die are sealed by the seal ring;
• the vacuum system comprises a vacuum unit and a vacuum tank;
• the vacuum unit is connected to the vacuum tank via a second valve;
• the vacuum tank is connected to the injection tube via a vacuum connecting pipe on which a third valve is disposed;
• and a joint of the vacuum tank and the injection tube is located between the melting chamber and the transition chamber;
• the protective gas supply system comprises a protective gas tank and a gas storage tank connected to the protective gas tank;
• the gas storage tank is connected to the injection tube via a gas tube on which a fourth valve is disposed;
• and a pipeline connecting the protective gas tank and the gas storage tank is provided with a first valve;
• and
• a telescopic observation window is disposed on the injection tube to monitor a molten state of the alloy material in the melting chamber.
