  • Patent number: 9289825
    Abstract: To transfer the molten metal that is melted in the melting furnace into the pouring ladle, which is a vessel for transporting the molten metal to the place for pouring, and to further lift the pouring ladle by another crane to pour the molten metal, requires time, such that the molten metal that had a high temperature when melted by the melting furnace is likely to cool down and to cause a defective cast product. To solve the problem the pouring equipment of the present invention pours the molten metal into the mold, comprising the melting furnace that produces molten metal by melting metal material and a driving apparatus that can move the melting furnace backward and forward or in a traverse direction, wherein the pouring equipment moves the melting furnace to the predetermined position by the driving apparatus, and then pours the molten metal into a mold by tilting the melting furnace relative to the mold.

  • Patent number: 8408278
    Abstract: An automatic pouring method whereby a tilting automatic pouring device can pour at high speed, accommodating high-speed molding on a high-speed molding line. The method includes: a step wherein a pouring hopper, which can hold an amount of molten metal sufficient for multiple pours, is tilted forward, thereby pouring the molten metal from the hopper into a casting mold; a step wherein the pouring hopper is tilted backward, thereby stopping the aforementioned pouring into the casting mold; and a step wherein a set of casting molds, including the casting mold for which the aforementioned pouring has been completed, are moved at intervals. During the period from the beginning of the step in which molten metal is poured into the casting mold to the end of the step in which the set of casting molds is moved at intervals, whenever the weight of molten metal in the pouring hopper is less than a prescribed weight, molten metal is continually supplied to the pouring hopper by tilting a holding furnace forward.
