[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jig for mounting a mold, and more particularly, to a jig for mounting a mold under a ram in a suspended state.

[0002]

2. Description of the Related Art As shown in FIG. 3, when a mold a is mounted under a ram b in a suspended state, it is conventionally mounted by a plurality of fixing bolts c.

[0003]

Therefore, according to the prior art, the fixing bolt c has to be turned many times one by one, which causes a problem that it takes too much time to attach and detach the mold a.

[0004]

SUMMARY OF THE INVENTION In view of the above, the present invention has been devised to solve the above-mentioned problems in the prior art, and in order to achieve this object, a shank portion is provided on the upper surface. A mold attaching jig for attaching the provided mold to a lower side of a ram in a suspended state, wherein the jig is fixed to the ram, and has a cylindrical portion into which the shank portion can be freely inserted and removed, and a circle of the cylindrical portion is provided. A holder provided with a penetrating part in a part of the circumference, and a substantially arcuate engagement notch which is inserted into the penetrating part so as to be rotatable in a substantially horizontal direction about one point and has a substantially arcuate shape and is provided on a side surface of the shank part An engaging member removably engaged with the collar, and a collar slidably mounted on the outer peripheral side of the cylindrical portion in a vertically slidable manner, when the engaging member is engaged with the engaging notch, The bow-shaped linear portion of the engaging member is the bow-shaped linear portion of the engaging notch. Touch to, and providing the engaging outer peripheral surface and the mold mounting jig characterized by comprising a substantially flush arcuate portion of the arcuate of the cylindrical portion of the member.

[0005]

When mounting the mold, the holder is fixed to the ram in advance, and the shank is inserted into the cylindrical portion while the engaging member is rotated to the outer peripheral side of the cylindrical portion. To engage the engagement notch, and slide the collar to the outside of the engagement member to lock the engagement state. In this engaged state, the bow-shaped linear portion of the engaging member comes into contact with the bow-shaped linear portion of the engaging notch, and therefore, the mold is circumferentially positioned with respect to the holder and the ram ( Installation angle). And this positioning is such that the arcuate arc portion of the engaging member is substantially flush with the outer peripheral surface of the cylindrical portion, and the collar is located outside thereof so that the engaging member cannot be rotated. There is no deviation. To remove the mold, the collar is slid in the opposite direction to release the lock, the engaging member is rotated to the outer peripheral side of the cylindrical portion to disengage from the engaging notch, and the shank portion is pulled out of the cylindrical portion.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the mounting jig includes a mold (upper mold) 1 provided with a shank portion 2 on the upper surface. It is attached to the lower side of the ram 3 in a suspended state, and has a holder 4, an engagement member 8, and a collar 11.

The holder 4 is fixed to a ram 3 such as a press by a fixing bolt 5, and has a cylindrical portion 6 at a lower portion thereof into which the shank portion 2 can be inserted and removed. A part of the circumference of the cylindrical part 6 is provided with a penetrating part 7 that penetrates the cylindrical part 6 in the radial direction.

The engaging member 8 is inserted into the penetrating portion 7 so as to be rotatable in a substantially horizontal direction around the pin 9 within a predetermined angle range, and has a planar shape as shown in FIG. It has a substantially bow shape, and is detachably engaged with a substantially bow-shaped engagement notch 10 provided on a side surface of the shank portion 2. In this engagement, the arcuate linear portion 8a of the engaging member 8 comes into contact with the arcuate linear portion 10a of the engaging notch 10 in a surface contact state, and the arcuate arc portion 8b of the engaging member 8 engages the cylindrical portion 6b. And is substantially flush with the outer peripheral surface of.

The collar 11 is an annular body, is slidably mounted on the outer peripheral side of the cylindrical portion 6 in a vertical direction, and locks the engaged state when positioned outside the engaging member 8. Release the lock when it comes off from the outside of 8.

Next, a method of using the mounting jig will be described.

First, when the mold 1 is mounted, the holder 4 is fixed to the ram 3 in advance, and the engaging member 8 is rotated to the outer peripheral side of the cylindrical portion 6 as shown by a chain line (counterclockwise in FIG. 2). ), And insert the shank portion 2 into the cylindrical portion 6 in this state. Next, the engaging member 8 is rotated (clockwise in FIG. 2) on the inner peripheral side of the cylindrical portion 6 to engage with the engaging notch 10 as shown by the solid line, and the collar 11 is slid outside the engaging member 8. Then, the engaged state is locked, and the mounting is completed as described above. Therefore, according to the mounting jig, mounting is extremely simple. In this engagement state, the arc-shaped linear portion 8a of the engagement member 8 comes into contact with the arc-shaped linear portion 10a of the engagement notch 10, so that the mold 1 is attached to the holder 4 and the ram 3. In contrast, positioning in the circumferential direction (fixing angle determination) can be performed. Further, in this positioning, the arcuate arc portion 8b of the engaging member 8 is substantially flush with the outer peripheral surface of the cylindrical portion 6, and the collar 11 is positioned outside the cylindrical member 6 so that the engaging member 8 is positioned. There is no deviation because it cannot rotate. Therefore, the mold 1 can be accurately mounted for positioning in the circumferential direction. When removing the mold 1, the collar 11 is slid upward to release the lock, the engaging member 8 is rotated to the outer peripheral side of the cylindrical portion 6 to disengage from the engaging notch 10, and the shank portion 2 is removed from the cylindrical portion. Pull out from 6. Therefore, according to the mounting jig, removal is very easy.

[0012]

[Effects of the Invention] The present invention has the following effects. That is,
After fixing the holder to the ram in advance, insert the shank portion into the cylindrical portion with the engaging member rotated to the outer peripheral side of the cylindrical portion, and rotate the engaging member to the inner peripheral side of the cylindrical portion to engage. The mold can be attached by a simple procedure of engaging the notch and sliding the collar to the outside of the engagement member to lock the engagement state. Also, in this engaged state, since the arcuate linear portion of the engaging member is brought into contact with the arcuate linear portion of the engaging notch, the die can be positioned in the circumferential direction with respect to the holder and the ram. it can. And this positioning is such that the arcuate arc portion of the engaging member is substantially flush with the outer peripheral surface of the cylindrical portion, and the collar is located outside thereof so that the engaging member cannot be rotated. Therefore, there is no deviation in the locked state. Therefore, the mold can be accurately mounted in the circumferential direction for positioning. It is also easy to remove.
