Method and apparatus for continuous semisolid die casting

A method for continuous semisolid die casting, the method being achieved using an apparatus for continuous semisolid die casting, the apparatus comprising:

• a first preparation device for producing a nucleating agent, a second preparation device for producing semisolid slurry, a semisolid die casting machine, and a central controller, the second preparation device comprising a slurry generator, and the method comprising:
• controlling, by the central controller, the first preparation device to produce a solid nucleating agent, and delivering the solid nucleating agent to the slurry generator of the second preparation device;
• controlling, by the central controller, the second preparation device to produce semisolid slurry, and delivering the semisolid slurry to the semisolid die casting machine;
• and
• controlling, by the central controller, the semisolid die casting machine to perform semisolid die casting;
• wherein the first preparation device comprises a resistance furnace and a sealed cap, and, controlling, by the central controller, the first preparation device to produce a solid nucleating agent, and delivering the solid nucleating agent to the slurry generator of the second preparation device comprises:
• putting spindles of the nucleating agent into the resistance furnace of the first preparation device;
• locking the sealed cap of the first preparation device;
• heating the resistance furnace to melt the spindles of the nucleating agent into a liquid nucleating agent with a preset temperature;
• heating a metal mold to a first preset temperature;
• closing the metal mold, and injecting the liquid nucleating agent into the metal mold;
• allowing the generation of the solid nucleating agent, and opening the metal mold;
• and delivering the produced solid nucleating agent to the second preparation device for producing semisolid slurry;
• wherein the preset temperature of the liquid nucleating agent is 650-700 degrees Celsius, and the first preset temperature of the metal mold is 180-240 degrees Celsius;
• wherein a mass of the solid nucleating agent transmitted to the slurry generator of the second preparation device accounts for 0.5-1.5% of that of the liquid slurry.
