る。[Prior art] As a conventional mold clamp device, the
As shown in Publication No. 14732 (Fig. 5), the short side 1 is held between the worm 18, the worm wheel 19, and the screw shaft 17 rotated by the worm wheel, with the long and short side support frame 20 as a fulcrum, or the short side 1 is actually Publication No. 58-23479 (Figure 6)
As shown in , it is composed of a threaded rod 4 that passes through water cooling boxes 3a and 3b that support a pair of long side plates, a spring 7 attached to one end (or both ends) of the threaded rod, and nuts 5 and 6. There is a mold clamping device.
[考案が解決しようとする課題]
前記従来技術は以下に述べる問題点を有してい
る。即ち実公昭52−14732号の場合(第5図参
照)、
イ 長短辺支持枠20が余分に必要となる。[Problems to be solved by the invention] The prior art has the following problems. In other words, in the case of Utility Model Publication No. 52-14732 (see Figure 5), (a) Extra long and short side support frames 20 are required.
ロ 短辺挾持のためにその支持枠がクランプ力の
反力に耐え得る大きな剛性を必要とする。(b) For short-side clamping, the support frame needs to have great rigidity to withstand the reaction force of the clamping force.
ハ 最適クランプ点を確保するためにクランプ点
相当部位の支持枠高さが、必要であり、結果的
に水冷箱高さとほぼ同等の高さが必要となる。C. In order to secure the optimum clamping point, the height of the support frame at the portion corresponding to the clamping point is required, and as a result, the height is required to be approximately the same as the height of the water cooling box.
ニ 前項ロ、ハの理由により支持枠が大きくなり
鋳型全体の外形寸法が大きくなると共に重量も
大きくなる。D. Due to the reasons mentioned in the previous section (b) and (c), the support frame becomes larger, the external dimensions of the mold as a whole become larger, and the weight also becomes larger.
ホ 以上のことは第1図に示す電磁攪拌装置を内
蔵した一対の水冷箱により複数のストランド例
えば2ストランド鋳造の場合、設置スペースの
制約により支持枠高さがとれずクランプ装置の
設置は不可となり鋳型として成立し得ない。E The above is because when casting multiple strands, for example, two strands, using a pair of water-cooled boxes with a built-in electromagnetic stirring device as shown in Figure 1, the height of the support frame cannot be secured due to installation space constraints, making it impossible to install a clamping device. It cannot be established as a mold.
更に実公昭58−23479号の場合(第6図参照)、
イ 複数のストランド例えば、2ストランド鋳造

内蔵された電磁攪拌装置があり、ネジ棒を水冷
箱を貫通して設けることができない。このた
め、電磁攪拌装置を貫通しなくてよい水冷箱の
上下端のクランプしかできず、水冷箱中央部の
クランプができない。Furthermore, in the case of Utility Model Publication No. 58-23479 (see Figure 6), (a) For example, in the case of two-strand casting, in the case of a clamping device that uses a threaded rod 4 that passes through a water-cooled box between the strands, a water-cooled box, etc. There is a built-in electromagnetic stirring device, and it is not possible to install a threaded rod through the water cooling box. For this reason, it is only possible to clamp the upper and lower ends of the water-cooled box without penetrating the electromagnetic stirring device, and it is not possible to clamp the central portion of the water-cooled box.
ロ この為、両端の短辺板に比較して中央部短辺
板と長辺板との接触部への溶鋼飛散物等の挟み
込みが発生し易く鋳型交換寿命が短くなる。(b) Therefore, compared to the short side plates at both ends, molten steel spatter is more likely to get caught in the contact area between the central short side plate and the long side plate, resulting in a shorter mold replacement life.

Appropriate allocation and averaging can be easily achieved. As a result, it is possible to prevent gaps from forming at the contact surface between the long side plate and the short side plate, preventing foreign matter from entering the contact surface, and reducing the mold replacement life caused by the formation and expansion of so-called corner gaps. extension is achieved.

鋳型の交換寿命は約100チヤージであり、これに
対して、水冷箱中央部に、本考案によるクランプ
装置を追加設置した鋳型のそれは約450チヤージ
と飛躍的な寿命延長が達成できた。 According to the knowledge of the inventors of the present invention, the replacement life of a mold with a clamping device configured to allow threaded rods to pass through the water-cooled box at two locations at the upper and lower ends of the water-cooled box to avoid interference with the electromagnetic stirring device is approximately 100 charges. In contrast, the life of the mold that was additionally installed with the clamping device of the present invention in the center of the water-cooled box was approximately 450 charges, significantly extending the lifespan.

置適用時にはその効果は多大のものがある。 In addition, the only space required to install the device is the space inside the pair of long-side molded water-cooled boxes, which is much smaller than conventional clamp devices that require installation space outside the water-cooled box. Since the installation space is small, the electromagnetic stirring device has a great effect when applied to a general mold.

るものである。 The present invention is not only applicable to molds in which it is impossible to penetrate the hole for the threaded rod of the clamp device into the water-cooled box for long-side molds, but also applies to the water-cooled box for long-side molds compared to conventional methods. Since it is only necessary to fix the stopper member, the production of the water-cooled box is easy and production costs can be reduced, and since the installation space is extremely small, it can be effectively applied to general molds.
