※ Description code in the drawing ※

6, the first piston 23, the second piston 24 and the bottom wall member 25 forming the lifting unit 2 is in close contact with the upper cylinder (11a) and lower cylinder (31) A plurality of "O-rings" are shown to prevent the high-pressure gas flowing out to the outside, and (7), a plurality of "couplings" for coupling the mold support part 1 and the mounting part 3. Screw ".

Referring to the operation of the mold transfer support device according to the present invention is configured as described above in detail.

As shown in FIG. 5, the mold transfer support apparatus 100 is installed in a plurality of U grooves 211 having a rectangular cross section on the upper surface of the bolster 210 of the press machine 200. At this time, as shown in Figure 6, according to the length of the bolster 210, the mold support 1 is formed of a single or a plurality.

As shown in Figure 4a, the outer end of the mounting portion (3) in the state in which the mold (D) is raised to the upper end of the mold support (1) of the mold transfer support device 100 installed in the press machine (200) High pressure gas is injected through the rising gas injection pipe (4) coupled to. The high pressure gas thus injected is first injected into the second upward pressure chamber 31a along the air passage 33 and the semicircular cross grooves along the air passage 24c formed in the second piston 24. Passed through 24b is injected into the first rising pressure chamber 11e.

As described above, when a high pressure gas is injected into the first rising pressure chamber 11e and the second rising pressure chamber 31a, the first piston 23 guides the upper cylinder 11a by the pressure. And sliding upward, the second piston 24 further pushes the first piston 23 along the coupling hole 25a of the lower cylinder 31 and the bottom wall member 25. Move upward in the form of raising.

At this time, the sphere 21 accommodated in the first piston 23 by the rising regulation jaw (11b) protruding to the inner upper end of the upper cylinder (11a) and the protrusion 23c of the first piston (23). Will not be allowed to rise anymore.

As described above, the mold (D) supported on the outer peripheral surface upper end of the sphere 21, is separated from the upper surface of the mold transfer support device 100 by a predetermined distance so that the operator can easily move to the desired position. Will be.

Meanwhile, when the mold D is moved by an operator, the sphere 21 is driven to rotate, and a plurality of the sphere driving balls 26 accommodated by supporting the bottom portion of the sphere 21 is the sphere 21. Rotate in the reverse direction. Therefore, the sphere 21 is more smoothly rotated by reducing the frictional force generated between the sphere 21 and the recess 23a of the first piston 23 by the load of the mold D. It will be possible.

And, as shown in Figure 4b, in order to return the sphere 21 accommodated in the lifting unit 2 after moving the mold (D) to the desired position by the above process, the After stopping the injection of the high pressure gas injected into the rising gas injection pipe 4 coupled to the mounting part 3, the high pressure gas is injected into the falling gas injection pipe 5 coupled to the first closing block 12.

Therefore, the high-pressure gas injected as described above is lowered of the upper cylinder 11a through the air passage 11c of the main body 11 along the air injection path 12b of the first closing block 12. It is injected into the pressure chamber 11d. The pressure is formed by the high-pressure gas injected into the lowering pressure chamber 11d, and thus the lifting part including the sphere 21 is pushed down by the protrusion 23c of the first piston 23. (2) is returned downward.

As apparent from the above description, according to the die transfer support apparatus of the present invention, the first piston and the second piston are lifted together by the high pressure gas injected into the first rising pressure chamber and the second rising pressure chamber. Therefore, even if only a very small amount of high-pressure gas is injected, there is an effect of simply raising the mold which is the weight body.

In addition, by injecting a high-pressure gas into the lower pressure chamber formed between the rising regulating jaw of the upper cylinder and the protrusion of the first piston, and automatically returns to the lifting unit including the sphere, a portion of the outer peripheral surface is continuously exposed to the outside. By protecting the spheres that were damaged or broken as a result it is possible to maintain a semi-permanent life.
