に、大きなバネを使用すればよいのであるが、スペース
上の問題で、バネの力を大きくすることができないとい
った欠点があった。However, in a conventional clamping device such as a die having such a structure, when it is used for a long period of time, rust is generated on the shaft portion for rotating the presser pawl or the presser foot is pressed. When rust occurs on the side surface of the claw, it is often impossible to move the presser claw with only the elastic force of the spring, making it difficult to smoothly repeat the clamp and release operations of the mold, etc. A large spring may be used in order to make the structure complicated or to increase the elastic force of the spring, but there is a drawback in that the spring force cannot be increased due to space problems.

クランプは解除される。When the die is to be clamped using the clamp device of the present invention, when pressure oil is introduced from the tightening side port into the hydraulic chamber and the piston rod chamber via the hydraulic passage, the ram piston moves up and the presser pawl moves upward. When the piston is moved rightward and the sliding member and the concave groove are engaged with each other, the presser pawl rotates counterclockwise about the shaft to clamp the mold with the tip of the presser pawl. Conversely, when pressure oil is introduced to the piston head side from the loosening side port, the piston moves to the left, the sliding member and the concave groove are loosened, and the holding pawl rotates clockwise about the shaft to release the clamp.
