１の凹部１ｂに挿入される。 In the second feed bar 2, guides 21 for guiding the first feed bar 1 and the second feed bar 2 are fixed on both sides of a plate 17 fixed to the machine frame 22a of the clamp unit 22. The first feed bar 1, which is carried in and out with the mold, and the second feed bar 2 on the remaining side are engaged with each other in the vicinity of the ends thereof, extending in the width direction and extending vertically. The movable bolster (not shown) of the second feed bar 2 can be freely engaged and disengaged by the vertical movement accompanying the vertical movement of the moving bolster (not shown). The tip 4a of the locate pin 4 fitted in the provided cylinder block 3 is connected to the first feed bar 1.
It can be fitted into and removed from the recess 1b. That is, the locate pin 4 is connected to a movable body 8, and the movable body 8 is biased to the left in the figure via a spring shaft 6 and a nut 7, which are built into the cylinder block 3 with a spring 5 mounted thereon. When pressurized fluid is sent from the fluid supply port 20 of the cylinder block 3 to the fluid chamber E, the built-in piston 9 moves and moves the movable body 8 to the right in the figure, thereby moving the tip 4a of the locating pin 4 to the first position. 1 to get out of the recess 1b of the feed bar 1. Conversely, when the pressure fluid in the fluid chamber E is discharged from the fluid supply port 20, the moving body 8 is moved to the left in the figure via the spring shaft 6 by the action of the spring 5.
Along with this, the locate pin 4 is inserted into the recess 1b of the first feed bar 1.

In order to perform this, a sliding plate 1 is attached to the bottom surface of the guide 21.
A bush 15 is fitted through the block 18 and the second feed bar 2, which are attached via the feed bar 6, and is detached by a snap spring 19.
次に本考案の作用について説明する。 Next, the operation of the present invention will be explained.

解かれたことを検出する。 In the upper half of FIG. 2, a moving bolster (not shown) is fed into a press, set on a bed (not shown), and the first feed bar 1 is attached to the protrusion 2a at the tip of the second feed bar 2. After the recess 1a at the end of the feed bar 2 is engaged, the locate pin 4 in the cylinder block 3 mounted on the second feed bar 2 is inserted into the recess 1b of the first feed bar 1, and the first feed bar 1 and the second feed bar 2 are connected. It shows the state that has been applied. In order to reverse the connection between the first feed bar 1 and the second feed bar 2 from this state, as shown in the lower half of FIG.
The piston 9 overcomes the spring 5 and moves to the right in the figure, and the moving body 8 comes into contact with the stopper 10, and the detection rod 11 of the limit switch 12 touches the tip of the spring shaft 6. 6a, and thereby the tip 4a of the locate pin 4 connected to the moving body 8 is connected to the first feed bar 1.
It is detected that the first feed bar 1 and the second feed bar 2 are completely pulled out from the recess 1a, and the horizontal connection between the first feed bar 1 and the second feed bar 2 is released.

全に解かれる。 Therefore, when the moving bolster (not shown) is lifted, the first feed bar 1 rises together with the mold, and the concave portion 1a of the first feed bar 1 is disengaged from the convex portion 2a of the second feed bar 2.
The connection between the feed bar 1 and the second feed bar 2 is completely released.

The first feed bar 1
Since the feed bar 1 and the second feed bar 2 are connected by engaging portions in two orthogonal directions, the connection is strong and reliable.Since the structure is simple, the overlapping part of both feed bars is short, and the total length of the first feed bar can be reduced. It can be made shorter.

り部分が従来のものより短かくてすむ。 In addition, since the engaging portion of the feed bar 1 and the second feed bar 2 due to the vertical unevenness is located near the ends of the first feed bar 1 and the second feed bar 2, the overlapping portion of the first feed bar 1 and the second feed bar 2 is different from the conventional one. It's shorter than that.
