FIG. 1 shows a plan view of a variable width mold apparatus 1 of the present invention, in which a substantially rectangular ingot casting hole 2a is formed on an outer frame 2 supporting the following long and short side molds 4 and 10. And a pair of short side molds 10 located at both ends between them and opposed to each other.
Having. Each of the long side molds 4 has an elongated thin plate shape made of an aluminum alloy, and has a central portion 5 having a slightly outwardly bowed center.
And elastically deformable ends 6 (hatched portions in the figure) at both ends. This central portion 5 is vertically fixed on the outer frame 2 along the side edge of the ingot pouring hole 2a. Further, the bow shape of the central portion 5 is for preventing and compensating for the dent deformation occurring on the long side due to the difference in shrinkage due to the difference in the cooling rate of each portion during solidification of the ingot. In addition, the short side mold 10
Is made of an aluminum alloy like the long side mold 4 and comprises a substantially rectangular parallelepiped main body 12 and contact pieces 14 fixed to both ends thereof, and can be moved in the direction of the arrow in the figure as described later. I have. The contact piece 14 is replaced when its end wears, but may be replaced with a piece integrated with the main body 12.

These pressing devices 20 are connected to the short side mold 10 via a projecting portion which will be described below and extends below the long side mold 4 provided at the end of the short side mold 10. The pressing device 20 contacts the end portion 6 of the long side mold 4 with the close contact piece 14 of the short side mold 10 by a cam mechanism described later. In addition, contacting / separating devices 50 are respectively provided on the outer frames 2 between the plates 8 fixed to the outermost ends of both ends 6 of each long side mold 4. These contacting / separating devices 50 abut both ends of the plate 8 that extend and contract to separate the opposite end portions 6 of the pair of long side molds 4 from each other.

As a result, the elastically deformable end 6 returns to the vicinity of the outer free position. Next, both ends of the contact / separation device 50 are extended and brought into contact with the plate 8 to separate the opposite ends 6 of the long side mold 4 from each other outward. Then, since the contact piece 14 is separated from the long-side mold 4, the short-side mold 10 easily moves in the direction of the arrow and is moved to a desired position. Next, as shown in FIG. 2B, both ends of the contact / separation device 50 are retracted and separated from the plate 8. Then
The end portions 6 of the long side mold 4 return to the vicinity of the free positions.
Finally, when the end 6 of the long side mold 4 is pushed inward by the pressing device 20, each end 6 is elastically deformed and comes into contact with the contact piece 14 of the short side mold 10 to be in a close contact state. Are defined. The above operation utilizes the elastic deformation of both ends 6 of the long side mold 4. In addition, long side mold 4
The free position of the elastically deformable end portion 6 is slightly outside the position where the long and short side molds 4 and 10 are in close contact with each other during casting by a distance pressed inward from the zero by a few mm by the pressing device 20. .

ものである。In order to change the position of the short side mold 10, the close contact between the long side mold 4 and the short side mold 10 by the pressing devices 20 on both sides is released in advance, and each end 6 of the long side mold 4 is removed. Return to near the free position. Next, the lever 5
5, the rotating plate 54 is rotated and the left and right links 60 are moved in the left and right directions, and the left and right push rods 64 and the pushers 66 are also pushed outward along with them, and the state shown in FIG. , And pushes the plate 8 against which each pusher 66 abuts outward. Then, each end portion 6 of the long side mold 4 is elastically deformed and spreads outward and apart from each other. As a result, the short side mold 10 can be easily moved to a new position because the contact piece 14 is separated from each end 6 of the long side mold 4 on both sides. When the lever 55 of the rotating plate 54 is pushed down horizontally, the left and right links 60 move obliquely toward the center, and the left and right push rods 64 and the pushers 66 also move toward the center along with them, and the respective pushers 66 move. Is separated from the plate 8. That is, in order to facilitate movement of the short side mold 10, the contact / separation device 50 temporarily separates the short side mold 10 from each end 6 of the long side mold 4 only during the movement.
