Definitions

  • This invention relates to a method and apparatus for supplying molten metal to a casting machine by using a ladle.
  • the operation of supplying molten metal is carried out by scooping up molten metal stored temporarily in a molten metal storage furnace with a ladle, conveying this ladle laden with the molten metal to a casting machine, and tilting the ladle to pour the molten metal in the ladle into a mold.
  • the amount of molten metal supplied to the mold must be appropriate in accordance with the cavity size of the mold.
  • the amount of molten metal supplied is too small, in the case of gravity casting, a riser does not function well, and in the case of die casting, a biscuit gets so thin that pressure is not sufficiently transmitted to a product portion, and a good casting cannot be obtained.
  • the amount of molten metal supplied is too large, in the case of gravity casting, the molten metal overflows from the mold cavity and worsens work environment, and in the case of die casting, a biscuit gets so thick that a chuck for holding the biscuit cannot grip the biscuit appropriately and a casting becomes difficult to be removed.
  • a biscuit means a portion formed between a plunger tip and a spool core. Before molten metal solidifies, pressure is applied to a product portion by way of molten metal in the biscuit portion. After casting is completed, this biscuit is gripped by a chuck to remove a casting from a mold.
  • the amount of molten metal supplied has been controlled by adjusting the inclination angle of the ladle, or by utilizing load detecting means such as a load cell when molten metal is scooped with the ladle from the molten metal storage furnace. More specifically, the ladle is inclined at a predetermined angle of inclination, and immersed in and lifted above the molten metal storage furnace with keeping the ladle inclined. Otherwise, the amount of molten metal in the ladle is detected by load detecting means such as a load cell and then excessive molten metal is overflowed by adjusting the inclination angle of the ladle delicately, if necessary. (Refer to Japanese Unexamined Patent Publication (KOKAI) No.sho63-309367.)
