After extending the hydraulic cylinder 7 and protruding the roller 6 of the lifter device 5 above the moving bolster 2, the feed screw 13 screwed into the carriage 11 is rotated by the motor 15, and the carriage 11 is moved in the direction of the arrow. By sliding the mold exchange adapter 17 on which the press mold 3 engaged with the carriage 11 is mounted, the mold exchange adapter 17 is moved from the moving holster 2 to the first station 9.

Next, move the moving bolster 2 in the direction of the arrow,
The moving bolster 2 is located on the side of the second station 10 of the mold exchange table 8.

Then, the mold exchange adapter 1 is placed on the second station 10 and has the press mold 3 to be used next set in advance.
7 mounted on the second station 10
2 is moved from the second station 10 onto the moving bolster 2 by sliding it in the two directions of the arrows.

The rest is the lifter device 6 installed on the moving bolster 2.
After shortening the hydraulic cylinder 7 of the lifter device 5, storing the roller 6 of the lifter device 5 in the moving bolster 2, and fixing the mold exchange adapter 17 on the moving bolster 2, the moving bolster 2 is slid in the direction of the arrow H. When the moving bolster 2 is set at a predetermined position on the press machine 1, the press mold replacement work is completed.

In this way, the replacement work of the press mold 3 is completed - when the press work by the press machine 1 is restarted, the mold change adapter 17 located on the first station 9 of the mold change table 8 during this press work The completed mold placed on the press mold 3 is removed, and the press mold 3 to be used for the next processing is set up externally.

When the press mold 3 set in the press machine is finished, the moving bolster 2 is moved to the side of the second station 10, as shown in FIG. The press mold 3 placed on -2 via the mold exchange adapter 17 is transferred together with the mold exchange adapter 17 to the second station 10.

Next, the moving bolster 2 is moved to the side of the first station 9, and the press die 3 used for the next processing, which has been set in advance on the first station 9, is transferred to the moving bolster 2 together with the die exchange adapter 17. After moving the
The moving bolster 2 on which the press die 3 has been placed is set again in the press machine 1 and press working is performed.

By repeating the above-described operations, the press die 3 set in the press machine 1 can be replaced efficiently.

As explained above, this invention has a lifter device that can be pulled out from the press machine in order to carry in and take out the press mold, and has a lifter device that has a number of rollers arranged on the top surface so that they can float up and down along the direction perpendicular to the direction of pull-out. a moving bolster having a moving holster, and first and second stations arranged side by side in the direction of the moving holster on one side of the pulling path of the moving holster; A mold changing table each equipped with a movable carriage and a press mold that can be mounted and fixed, detachably connected to the carriage on the mold changing table, and carried integrally with the press mold on a moving bolster.
