  • the two actuators 105 are able to move the inner cooling gas nozzles 103 and the support rods 104 in a up-and-down direction (vertical direction) and the horizontal direction in synchronization with each other. Therefore, it is possible that the inner shape defining members 102 a 1 , 102 a 2 , 102 a 3 and the outer shape defining member 102 b are moved in a downward direction as the molten metal surface is lowered along with progress of casting.

In the example shown in FIG. 2A and FIG. 2B , each of four corners of the outer shape defining member 102 b is chamfered. Further, projecting parts, which project in the x axis direction, are provided in four corners of the opening, respectively.

  • the inner shape defining member 102 a 2 located in the center of the shape defining members 102 is able to be partitioned in the x axis direction along the symmetry axis that is parallel to the y axis.
  • An interval between the inner shape defining members 102 a 1 , 102 a 2 , 102 a 3 and the outer shape defining member 102 b serves as a molten metal passage portion 102 c (a hatching part) through which the molten metal passes.
  • the shape defining members 102 are able to be partitioned in the x axis direction along the symmetry axis (a parting line) that is parallel to the y axis. In other words, it is possible to switch the shape defining members 102 between a joined state and a partitioned state. Hence, it becomes possible to branch the casting M 3 by switching the shape defining members 102 from the joined state to the partitioned state while casting. Moreover, it is possible to integrate the branched casting M 3 together by switching the shape defining members 102 from the partitioned state to the joined state while casting. In other words, by using the shape defining member 102 according to this embodiment, it is possible to manufacture the casting M 3 having the branched structure. Details of the casting M 3 having such a branched structure will be described later.

  • the other ends of the arms A 1 , A 2 are placed on a guide G that extends in the y axis direction, so that the other ends of the arms A 1 , A 2 are able to slide.
  • the molten metal cutters C 1 , C 2 are able to slide in the y axis direction.
  • the guide G is able to move on the xy plane and in the z axis direction, following the shape defining members 102 .
  • the molten metal cutters C 1 , C 2 are arranged on an upper side of the shape defining members 102 , and a lower side of the solidification interface in the z axis direction.
  • it is preferred that the molten metal cutters C 1 , C 2 are provided as close to the shape defining members 102 as possible.
  • molten metal cutters C 1 , C 2 are arranged so as to face each other through the retained molten metal M 2 , which has been drawn up from the shape defining member 102 , on the symmetry axis that is parallel to the y axis of the shape defining member 102 . In other words, the molten metal cutters C 1 , C 2 are not inserted into the retained molten metal M 2 .
  • the molten metal cutters C 1 , C 2 move in the Y axis direction so as to be closer to each other.
  • separation of the retained molten metal M 2 by partitioning of the shape defining members 102 is promoted.
  • Just partitioning the shape defining members 102 may not be sufficient for separating the retained molten metal M 2 as desired due to surface tension of the retained molten metal M 2 . Therefore, by inserting the molten metal cutters C 1 , C 2 into the retained molten metal M 2 at the same time as partitioning of the shape defining members 102 , it is possible to ensure that the retained molten metal M 2 is separated. Therefore, it is possible to improve dimensional accuracy of the branched structure of the casting M 3 .
