Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a mold hanging and mounting device for automatically attaching and detaching a mold to a conveyance device when transferring the mold to a press machine or the like.

Conventional technology and its problems When press processing is performed using a mold, there is no problem in replacing the mold in the case of high-volume production of a small number of products, but it takes time to replace the mold in the case of high-mix, low-volume production. However, especially when the mold is large and difficult to handle manually, it is difficult to transfer it to a press machine or the like and perform positioning. In addition, the power supply to the mold or the connection of the hydraulic pressure source cannot be automatically performed, so there is a drawback that it takes a long time to replace the mold.

Furthermore, in recent years, a series of press working processes has been automated by computer control or the like. In this case, replacing the mold manually takes a long time, and
There are problems such as that the time is not constant, which is a factor that hinders automation.Means for solving problems The present invention for achieving the above object will be explained with reference to FIGS. 1 to 3. The mold hanging mounting device 1 of the present invention includes an upper mold 2,
It consists of an adapter plate 4 and a base plate 6 which are respectively attached to the lower mold 3.

The adapter plate 4 is detachable from a press machine (not shown) and has a constant shape regardless of the shape and size of the upper mold 2. The base plate 6 also has a constant shape that matches the bolster 11 of the press regardless of the shape and size of the lower mold 3, and is provided with a positioning means 12 for removably placing it in a fixed position with respect to the bolster 11. Further, a power supply plug 10 and a hydraulic plug 24 connected to the lower mold 3 are provided. Furthermore, the pace plate 6 has a connecting tool 16 and a hydraulic connecting tool 26 t-11i that are removably fitted to the power supply port provided on the bolster 11 when placed in a fixed position relative to the bolster 11.
fff I can get it.

Operation The upper and lower molds 2 and 3 are assembled, an adapter plate 4 and a base plate 6 are attached to each, and the molds are placed on the pulled out bolster 11. In this case, the base plate 6 is positioned at a fixed position on the bolster 11 by the positioning means 12,
And the connection tool 16 and the hydraulic connection tool 26 are automatically connected to the power supply port 1.
5 and the hydraulic port 25. Therefore, by returning the bolster 11 to the press working position, the molds 2 and 3 are positioned at the working axis position of the press machine, and the knock bottle etc. can be operated from the outside.

Therefore, when replacing the mold, the base plate 6 can be positioned with the bolster and automatically attached to and removed from the bolster, keeping the overall external dimensions constant when the mold is hung, and setting the hanging point. The purpose is to automatically lift and lower the mold at a constant rate.

In the drawings of the embodiment, the mold hanging and mounting device ill consists of an adapter plate 4 that is attached to the upper mold 2 and a base plate 6 that is attached to the lower mold 3. The adapter plate 4 is fixed to the upper die 2 by appropriate means, and includes a positioning notch 5 for engaging with a slide shank (not shown) that moves up and down of the press. The adapter plate 4 has a constant size so as to fit the slide shank, regardless of the shape and size of the upper mold 2. As a result, regardless of the shape of the upper mold, it is possible to center the mold and to grip it reliably by a certain gripping mechanism (not shown) provided on the slide shank.

The base plate 6 includes a mold positioning key 7 for mounting the lower mold 3 at a predetermined position and a tightening bolt 8. The lower mold 3 is usually equipped with a knockout pin that is operated electrically or hydraulically. 1 The base plate 6 is equipped with a power supply plug 10 and a hydraulic port 25 to connect the power supply and operation circuit to the knockout pin, and the lower mold 3 is always connected to the knockout pin. Connected.

This base plate 6 also has a shape that is constant regardless of the shape and dimensions of the lower mold 3 and is compatible with the bolster 11 of the press machine. It is provided with a positioning means 12, and a connector 16 and a hydraulic connector 26 which are connected to the power supply plug 10 and the hydraulic plug 24 and fit into the power supply port 15 and the hydraulic port 5 such as an outlet provided on the bolster 11. The positioning means 12 includes, for example, a key 13 for determining the mounting position attached to the bolster 11, and a key groove 14 cut out in the lower surface of the base plate 6 and fitted into the key 13. The above-mentioned fixed position is a position where the upper and lower molds 2 and 3 are aligned to the processing axis when set to the bolster lit press processing position, and the lower mold position determining key 7 provided on the base plate 6 and the positioning means minor The connector 16 and the hydraulic connector 26 are provided facing each other so that they can be automatically attached to and detached from the power supply port 15 and the hydraulic port 5 when the base plate 6 is attached to and detached from the bolster 11. 17 This is a hanging tool such as a hanging ring that engages with the tongue rack attached to the base plate 6. This hanging R17 is attached at a fixed position. As a result, the vertical position of the suspension remains constant regardless of the size of the mold, and various molds can be transported with one set of tongs. Note 18
is a clamping plate for the base plate 6 attached to the bolster 11.

Note that the positioning means 12 is not limited to the device using the fitting between the key 13 and the keyway 14 shown in this embodiment, but may include, for example, a metal fitting that corresponds to a groove provided on the bolster and a groove provided on the lower surface of the pace plate. Of course, it is also possible to use devices that fit together.

FIG. 4 shows another example of the base plate. The base plate 20 of this example is designed to be conveniently transported by a forklift, etc., and has an inverted plate-like cross section and a fork insertion hole 21 drilled in the side edge. There are some differences between the two, and the same parts are given the same reference numerals and their explanations will be omitted.

In the above configuration, an adapter plate 4 and a base plate 6 are attached to the upper mold 2 and the lower mold 3, respectively, and the assembled molds are stored in a proper place. When installing on the press machine, pull out the bolster 11 and attach the conveyor device (not shown).
The tongs are engaged with a hanging tool 17 such as a hanging ring, and the assembled dust is conveyed onto the bolster 11 together with the adapter plate 4 and the base plate 6, and fixed by fitting into the keyway 14t and the key 13 for determining the installation position. Can be set in any position. At the same time, the connector 16 and the hydraulic connector 26 are fitted into the power supply port 15 and the hydraulic port 25, and various operations such as protruding and retracting the knockout pin can be performed from the outside via the bolster 11.

Thereafter, by returning the bolster 11 to its normal position, the adapter plate 6 faces the slide shank of the press, and pressing can be performed immediately.

Effects of the Invention The present invention consists of an adapter plate and a base plate that are respectively attached to upper and lower molds, each plate has a constant shape regardless of the shape and dimensions of the mold, and the adapter plate, mold, and base plate are integrated. When transporting the mold, it is assembled and transported and placed on a bolster, and when placed, it is positioned in a predetermined position and the electric and hydraulic circuits are automatically connected, so that the mold can be easily attached to and removed from the press machine. This can be carried out extremely easily and quickly, and even by remote control, and therefore has the advantage of being able to be carried out efficiently even in the case of high-mix, low-volume production.
