Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an automatic mold conveyance device configured to place a mold and automatically convey it to a mold mounting board.

[Problems that conventional technology and ideas try to solve]

Conventionally, the setup work for attaching a mold to a mold mounting board, that is, a die plate of a molding machine, involves lifting the mold with a crane, placing it on an automatic mold transport device, fine-tuning the crane operation, and moving the mold along the mounting board. It was just touching the positioning side wall of the automatic mold transfer device. Therefore, the setup work was quite time-consuming.

Therefore, it is an object of the present invention to shorten the work time required to place a mold on the automatic mold conveyance device of the type mentioned at the beginning.

[Means for solving problems]

The present invention is intended to achieve the above-mentioned purpose in an automatic mold conveying device in which rollers and treads are alternately arranged on a mounting surface so that molds are placed and automatically transported to a mold mounting board. a first mold guide plate, which is attached to the tread plate at a distance from the side wall of the conveying device in parallel in accordance with the thickness of the mold flange, and has rollers mounted in a row; a second mold guide plate which is pivoted at one end to the tread and is also equipped with rollers; and a third mold guide plate following this guide plate and which is also equipped with rollers. An L-shaped metal fitting is installed below the other end of the second mold guide plate, and a vertical part is inserted into the foot plate at the position of this metal fitting along the rotation path of the vertical part of the metal fitting. An arcuate slit is formed, along which a plurality of pin holes into which locking pins for locking the horizontal portion of the metal fitting are inserted are arranged, and L-shaped holes are formed at both ends of the third mold guide plate. The metal fittings are each lowered, and a slit is formed in the footboard at this metal fitting position in a direction perpendicular to the side wall so that the vertical part of the corresponding metal fitting can be inserted, and the corresponding metal fitting is inserted along this narrow gap. It is characterized by a plurality of pin holes arranged into which lock pins are inserted to lock the horizontal portion.

[Effect]

The second mold guide plate is set to the diagonal position by rotating the vertical part of the lower metal fitting along the arc-shaped gap, and then the lock pin is inserted through the pin hole corresponding to the lock position in the horizontal part. be done. Third
The mold guide plate is connected to the other end and parallel to the vertical part of the lower fitting, which is positioned along the slot and locked with a locking pin. As a result, the guide path of the mold flange gradually narrows from the first mold guide plate toward the third mold guide plate. Therefore, when placing the mold on the mounting surface, the mold flange is placed on the wide guide path defined by the first mold guide plate and automatically transported, and the mold is placed on the third or second mold. After coming into contact with the guide plates, the mold is guided along these, enters the guide path defined by the third mold guide plate, and is positioned at the regular conveyance position.

[Example of idea]

In FIG. 1, 1 is a fixed mold mounting board of, for example, a horizontal clamping type injection molding machine, and 2 is an automatic mold conveying device in which driving rollers 3 and tread plates 5 are alternately arranged on the mold mounting surface. 4 is a side wall that functions as a positioning plate and on which rollers are arranged.
10 is a first mold guide plate, and rollers 1 are arranged in a row.
1 is installed, and the distance between the side wall 4 and the roller is set to the mold 8.
The tread plate 5 and the lower auxiliary plate 9 (the fourth
(Fig.) is fixed. Reference numeral 20 designates a second mold guide plate, and as shown in FIG. is installed below. The vertical part of this fitting is narrower than the horizontal part. Similarly, rollers 21 are arranged on the side. Reference numeral 30 designates a third mold guide plate, and as shown in FIG. 3, a roller 31 is similarly mounted thereon, and L fittings 32 having narrow vertical portions are similarly provided at both ends thereof.

On both footboards 5 below the mold guide plate 30,
A slit 35 is formed into which the L fitting 32 is inserted, and a slit 36 is formed in the auxiliary plate 9 below the slit 35 into which a protrusion 32a provided on the bottom of the L fitting 32 is inserted (Fig. 4). ). Further, around both the narrow gaps 35 and 36, pin holes 37 and 38 are arranged at positions corresponding to the pin holes 32b of the L fitting 32, and the lock pin 3
9 is inserted.

The pin 22 of the mold guide plate 20 is pivotally attached to the foot plate 5 and the plate 9 so as to be rotatable. A slit 25 is formed in one of the footboards 5, into which an L metal fitting 23 can be inserted and rotated, and a protrusion 23a provided at the bottom of the L metal fitting 23 is inserted into the auxiliary plate 9 below the slit 25. A correspondingly shaped slit (not shown) is formed. Further, around these gaps, pin holes 27 are provided at positions corresponding to the pin holes 23b of the L fitting 23.
(The auxiliary plate 9 is not shown) are arranged so that the lock pin 39 can be inserted. These structures are similar to those in FIG.

During the setup work, first, using the mold guide plate 20 with the pin 22 as a fulcrum, the projection 23a and the narrow vertical part of the L fitting 23 are inserted into the narrow gap, taking into account the shape of the mold 8, the position of the crane, etc. The lock pin 39 is inserted through the pin hole 27 of the footboard 5 and passed through the pin hole 23b to the pin hole of the auxiliary plate 9. Next, the vertical part of the L fitting 32 and the protrusion 32a are connected to the mold guide plate 30 through the narrow gap 35 and the protrusion 32a.
36 in parallel to the mold guide plate 2.
At the position corresponding to 0, insert the lock pin 39 into the pin hole 37,
32b, 38 and lock it. Then, the mold 8 is placed as shown in FIG. 5 and conveyed by the rollers 3. From the point at which the tip or rear end of the flange 8a hits the mold guide plate 30, or in some cases the mold guide plate 20, the mold 8 is guided along these 20, 30, and further along the mold guide plate 10. The mold is guided to the proper position on the mold mounting board 1.

In addition, the lock mechanisms 23, 23a, 23b, 25,
27 and 32, 32a, 32b, 35-38, 3
A modification may be considered, such as making the footboard 5 itself strong instead of the footboard 9 and configuring only this footboard.

[Effect of idea]

As described above, according to the present invention, there is no need to precisely set the position when placing a mold on a mounting surface that is automatically transported. In other words, by arranging the three mold guide plates, there is no need to finely adjust the position of heavy objects.
It is automatically carried into the correct position on the mold installation board, reducing setup time. The positioning member of the mold guide plate can also be easily constructed without being bulky by using an L-shaped metal fitting provided below the guide plate and a hole in the foot plate.
