However, the former has a large-scale structure, not only a large installation area, but also a large equipment cost, the apparatus itself is large, heavy and difficult to move, and the latter is heavy. When the width of the object changed, it could not cope. Furthermore, it was not possible to change the sideways angle.

It is an object of the present invention to provide a large-scale structure as described above, which requires not only a large installation area, but also a large facility cost, and the apparatus itself is large and difficult to move. Eliminating the drawbacks of not being able to cope with the width change and sideways angle as in the latter, the structure is simple, the equipment cost is not required, the device itself can be easily moved, and it can also cope with the width change and sideways angle. It is an object of the present invention to provide a die overturning device.

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention has a curved portion which is curved with respect to a lower surface, and an upper portion has a floor surface which supports two perpendicular surfaces of a mold such as an injection molding machine. The mold is mounted on a horizontal table that is parallel to the mounting surface and a support surface that is perpendicular to the mounting surface, and the mold is turned over from the one mounting surface side to the other supporting surface side by the lower curved part. In the apparatus, the lower portion has a curved portion curved to the floor surface, and the upper portion is a mounting surface parallel to the floor surface and a right angle to the mounting surface, which supports two perpendicular surfaces of a magnetic metal mold such as an injection molding machine. And a pair of guide bars mounted parallel to the support surface at both ends of the fixed horizontal table, and a pair of guide bars mounted on both ends of the fixed horizontal table as guides. A movable horizontal table with the same structure as the fixed horizontal table that can be moved forward and backward with respect to the fixed horizontal table The fixed, removably attached by a pair of pins on both its side stand mounting surface of each of the mobile,
A pair of fixed blocks for fixing and positioning the mold mounted on the mounting surface, and the mold lying down to maintain a predetermined angle with respect to the floor when the mold is fallen from one side to the other. At this time, a mold side-down device having a pillow having a magnetic material previously attached to the other surface of the mold was used.

Further, the magnetic property of the pillow has ON / OFF means, so that it can be easily attached to and detached from the other surface of the mold, and the jack can maintain the pillow at a predetermined angle. A die-side-down device that can be operated with bolts and hydraulic jacks.

Adjustment is made in accordance with the width L of the mold 12 and the thickness T of the mold 12 is adjusted.
A pair of pins 1 attached to the fixed block 18 in a pair of holes 17a located closest to the mold thickness T from the support surface 13b selected from the plurality of pairs of holes 17 in the mounting surface 13a in accordance with
9 can be further inserted into the fixing block 18.
The mold 12 is fixed to the mounting surface 13a and the support surface 13b by pushing and pulling the adjustment bolt 20 provided in the above in the axial direction, and is positioned.

The mold 12 is moved from one surface 12a to the other surface 12a.
b, the supporting surface 13b, ie, the other surface 1 of the mold,
2b is the height d of the support surface 13b which is parallel to the floor surface FL.
A pillow 22 having a magnetic body 21 with a height d that is attached to the other side 12b of the magnetic body in advance when the mold 12 is turned over so that Here, the height d is not limited to the pillow 22 previously set at a predetermined height as described above, but can be variously selected with a jack bolt or a hydraulic jack, for example, and the cavity of the mold 12 is repaired. In this case, the angle can be maintained so that the work can be easily performed. ,

The magnetic body 21 of the pillow 22 can be turned on and off by a switch or the like, as well as the magnetic body 21 of the pillow 22, and can be freely attached to and detached from the other surface of the mold.

The operation is as described above. Next, the operation of the apparatus will be described with reference to FIG.
As shown in (1), the mold 12 is suspended on the mounting surface 13a of the mold overturning device 10 by a crane, and the two perpendicular surfaces 12a and the other surface 12b of the mold 12 contact the mounting surface 13a and the support surface 13b, respectively. At the same time, as described above, the mold 12 is fixed to the both surfaces 13a and 13b by the fixing block 18 and positioned, so that when the mold 12 is turned sideways on the other mold surface 12b in advance, the mold 12 is horizontally The pillow 22 having a height d is attached by the magnetic body 21 so that

Next, the crane is lowered and moved to the right in the figure as shown in (b), and as shown in (c), the mold 12 is horizontal with respect to the floor surface FL, that is, 90 ^. After turning over, the fixed block 18 is removed, and the lower die shown in the figure can be corrected or cleaned by removing the upper die as shown in (d).

[0010]

As described above, the present invention has a large structure, a large installation area, a large equipment cost, a large size of the apparatus itself, and a difficulty in moving. The system has a simple structure, does not require equipment costs, can be easily moved, and can respond to changes in width and angle, and has a fixed structure. Because it is simple and lightweight with a pair of guide bars between the moving sideways,
The apparatus itself can be easily moved, the width and thickness of the mold can be easily adjusted, and the apparatus does not require equipment cost.

Although this apparatus has been described as a die-side down apparatus, the present invention is not limited to this, and it goes without saying that any iron heavy object having two perpendicular surfaces can be used.
