車されていなかった。For example, as a method for fully automatic mold clamping,
There is No. 9-42208. As shown in FIG. 2, the device disclosed in this publication includes a plunger 3 which is installed at a predetermined position on a mold mounting plate 10 so as to be able to elastically slide in a direction substantially perpendicular to the mold mounting surface 2. The mold attachment hook 4 is rotatably provided by providing a wedge insertion hole 5 at the other end of the plunger, and inserting a cutout 7 having one end connected to a hydraulic cylinder 6 into the wedge insertion hole. ing. However, the mold mounting device according to this proposal has a structure in which the main components such as the plunger and the mold mounting hook are all housed within the mold mounting plate, resulting in space limitations. Furthermore, the processing requires time. In addition, in the unlikely event that the pressure inside the hydraulic cylinder decreases due to a failure in the hydraulic system during clamping, an oil leak, etc., there is a risk that the wedge will rise and the mold attachment hook will detach from the mold, causing the mold to fall. The vehicle was not dispatched.

The link mechanism was used to obtain a strong lamp force. In addition, as a mechanism for operating the clamp device, the link is rotated via rollers, and the rollers have a slope on the surface where they come into contact with the presser plate that directly clamps the mold, and the clamping force is adjusted by this difference in slope. It has a mechanism that opens and closes.

In FIG. 4, a through hole 11 is formed at a predetermined position of the upper table 8 in a direction substantially perpendicular to the front surface 9 of the upper table, through which the shaft 10 passes. The shaft 10 is supported by a first bearing 12 and a second bearing 13 at both ends of the through hole 11, and one end of the shaft 10 is operated by a presser plate 15'r which is operated by the ramp force required when installing the mold 14 and when it is installed or removed. It is connected to an air cylinder 16 through a lever 17 via a pin 25. On the other hand, at the other end of the shaft 10, there is a rotating mechanism for operating the presser plate 15.
A link 18 that can be interlocked is attached by a nut 26. One end of the first roller 20 rotates on the sloped surface 19 of the upper surface of the presser plate 13, and the bolt 27 is attached to the first roller 20.
The second roller 2 that rotates the front surface 9 of the upper table in conjunction with this
1 and a bolt 28 for attaching it. Further, during unclamping, the holding plate 18 is pushed up by the coil spring 28 embedded in the VC hub plate surface 22. Next, in FIGS. 1 and 3, the air cylinder 16 and the link 1 are shown in the clamped state of this device.
8 shows the relationship. That is, the point is that the piston rod of the air cylinder 16 is mounted so as to be clamped in a retracted state.

き安全性が高い。According to the present invention, since air is used as a power source, piping, turning, and control are easy, so that an automatic mold clamp that is inexpensive and has an extremely short operating time can be provided. Furthermore, since a man-link mechanism is used as the clamping force transmission mechanism, a strong clamping force can be obtained with a relatively small force. Furthermore, when clamping the mold, the piston rod of the air cylinder is clamped in a retracted state, which prevents the mold from falling due to lowering of the air cylinder, resulting in high safety.
