行う事が出来る。As shown in FIGS. 1 and 2, a fixed casting mold 1 and a pair of short side frames 2 provided therein are provided in a continuous casting mold capable of changing the thickness in a wide range according to the present invention. In the continuous casting mold in which the thickness is variable, the free side long side frame 5 is formed by fastening the fixed side long side frame 4 having one side fixed to the fixed frame 1 and the free side long side frame 5 having one side movable. The fixed-side long side frame 4 is a hydraulic jack 6 as a long side clamping device.
Further, it is supported by a buffer spring 7 by a thickness changing hydraulic cylinder 8 and a long side clamping force releasing cylinder 9 having a lock mechanism. Therefore, it is possible to change the thickness over a wide range. Further, the long-side clamp operation and the long-side clamp release operation when changing the thickness can be performed quickly in a short time.

First, in order to release the clamping force, the long side clamping force releasing cylinder 9 having a lock mechanism is operated to the push side,
The clamping force of the buffer spring 7 is released. Next, the thickness changing hydraulic cylinder 8 is operated toward the push side to widen the space between the long side frames, remove the first short side frames 2 and 3 and insert the short side frames 10 having different thicknesses between the long side frames. . Next, the thickness changing hydraulic cylinder 8 is moved to the pulling side and set at a predetermined long side frame interval. Then, the clamping hydraulic jack 6 is moved to the push side to contract the buffer spring 7 and set the clamping force. Further, the clamping force is locked by setting the hydraulic pressure of the long side clamping force releasing cylinder 9 having the lock mechanism to 0. Next, the clamp hydraulic jack 6 is operated to the pulling side to retract the rod of the hydraulic jack 6.

This will be described with reference to FIG. The fixed frame 1 and a pair of short side frames 2 and 3 provided on the fixed frame 1 are fastened by a fixed long side frame 4 having one side fixed to the fixed frame 1 and a free side long side frame 5 having one movable side. In the continuous casting mold whose thickness can be changed, the free side long side frame 5 and the fixed side long side frame 4 have a hydraulic jack 6 and a buffer spring 7 as long side clamping devices, a thickness changing hydraulic cylinder 8 and a lock. It is supported by a long side clamping force releasing cylinder 9 having a mechanism. The lock mechanism in the cylinder rod portion 11 of the long side clamping force releasing cylinder 9 provided with this lock mechanism is a bare lock mechanism here. This is composed of a cylinder rod portion 11 and a sleeve 12, as shown in FIG.
It is in the state of a tightening spring, mechanically fixing the cylinder rod 11 at any position of the stroke. When hydraulic oil flows between the sleeve 12 and the cylinder rod 11, the sleeve 12 is expanded in the circumferential direction and the sleeve 12 is expanded.
The cylinder rod 11 has a mechanism for canceling the interference between the cylinder rod 11 and the cylinder rod 11 and providing a clearance allowing the cylinder rod 11 to stroke with a minimum resistance.

遠隔操作で、しかも短時間に行う事が出来る。Thus, even in the event of an accident such as a pressure drop in the hydraulic system, the lock force is automatically restored if the pressure in the sleeve 12 decreases, and the lock force is retained. Therefore, even if an accident such as a pressure drop in the hydraulic system occurs, the long-side clamping force is retained and no trouble such as breakout occurs. Further, according to the present invention, the release of the long-side clamping force and the setting of the clamping force when changing the thickness can be performed remotely and in a short time.

い、 等の優れた効果を発揮するものである。As described above, according to the mold for continuous casting of the present invention, the thickness of the cast piece can be set in a wide range, the workability when changing the cast piece thickness is improved, the time is shortened, and the cost is reduced. By providing a long side clamp force release cylinder equipped with a lock mechanism that can contribute to down, the long side clamp force is retained even if an accident such as pressure drop of the hydraulic system is held, and it does not lead to trouble. It is effective.
