Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a die structure of a punching device for punching a printing paper into a predetermined shape for making a paper box (cosmetic box) for packing, for example.

[0002]

2. Description of the Related Art Paper boxes (decorative boxes) used for packing various products are printed with necessary characters, figures, etc. on the paper as shown in FIG. The product portion B is taken out from the printing paper D in which the notch A is made and the product portion B is assembled in a box shape.

Conventionally, the work of taking out the product portion B from the printing paper D may be performed manually one by one, but normally, the male die E shown in FIG. (Press machine) G, the female mold F shown in FIG. 6 is set on the fixed table H shown in FIG. 7, the printing paper D is laminated on the female mold F, and the lifting / lowering pressure is applied in that state. The male mold E is pressed from above the printing paper D by the body G, and the male mold E is opened by the opening I of the female mold F.
The product part B is punched out by pushing it inside.

As shown in FIG. 6B, the male mold E and the female mold F shown in FIG. 6 have a cutting line of the printing paper D on one plate J (usually a veneer plate having a thickness of about 15 mm is used). It is produced by forming a kerf K in the same manner as A, and the one extracted from the inside of the kerf K is a male mold E, and the one left after the male E is extracted is a female mold F.

Conventionally, the male die E printing paper punching device is attached to the lifting body G as shown in FIG.
Arrange a desired number of iron metal fittings M having a protruding pin L of about m on the male mold E, and hit them with a hammer N from above to cause the pins L of the iron metal fitting M to bite into the upper surface of the male mold E. After connecting the male mold E and the iron fitting M, the iron fitting M was attached to the electromagnet O of the elevating body G of the printing paper punching device shown in FIG. When attaching the male die E to the lifting body G, the male die E and the female die F must be aligned so that they can be fitted to each other.

[0006]

However, the printing paper punching device and its male mold E and female mold F have the following problems. . Since the structure is made such that the pin L of the iron fitting M is driven into the male die E and the iron fitting M is attached, the male die E is easily cracked or damaged. Further, when the printing paper D is punched out by the male die E having cracks or the like, the cracks further progress and the male die E may be damaged in some cases. . After attaching the iron fitting M to the male die E, the same iron fitting M
, The holes of the pins L of the iron fitting M remain in the male mold E, so that the iron fitting M cannot be repeatedly attached at the same position. Therefore, when it is necessary to attach and detach the male mold E and the iron fitting M many times, the mounting position of the iron fitting M must be changed each time. However, in this case, holes are formed on the surface of the male mold E in many places, and the male mold E is damaged. . When the male mold E and the female mold F of the printing paper necessary for assembling a small paper box are made of wood, a small (not shown) protrusion is formed in the inner opening of the female mold F, and dozens of sheets are left as they are. It is not possible to punch out the overlapping printing paper D. Therefore, in this case, the number of printing papers D to be set is reduced, or a metal mold is used (manufacturing cost is higher than that of a wooden mold, and when a large amount of the same printing paper is punched). Other than that, the profitability is not good), or a method of manually pulling out the product part B one by one must be taken. . Since the exciting region of the electromagnet O of the lifting body G to which the iron fitting M is attached / detached is not divided into a plurality, the attracting force on the surface of the electromagnet O is uneven, and even if the iron fitting M is attached at a desired position, that portion If the electromagnetic force of is weak, it may be attracted to the part with strong electromagnetic force and move. In this case, the mounting position of the male mold E is deviated, and the fitting with the female mold F becomes unsuccessful.

It is an object of the present invention to provide a die structure of a paper punching device which can be repeatedly attached to and detached from a printing paper punching device, has less pain in the die, and can be set in an accurate mounting position. is there.

A female screw (demon eye nut) 11 for attaching a connector and a removable male screw 12 are attached.

Reference numeral 10 shown in FIG. 2 is a pressurizing machine of the printing paper punching device, and an electromagnet 30 having a plurality of exciting regions 21 is arranged on the lower surface (adsorption surface 15) of the pressurizing machine 10. The pressurizer 10 can be moved up and down by a hydraulic cylinder (not shown).

Reference numeral 35 shown in FIG. 2 denotes a fixed base of the printing paper punching device, which is arranged directly below the pressurizing machine 10. The fixed base 35 is formed in a rectangular frame shape, and a support portion 36 (FIG. 3) for mounting the female mold 7 is formed inside the frame. Therefore, when the female die 7 is placed on the fixed base 35, the female die 7 is fixed inside the fixed base 35.

[0020]

According to the die structure of the paper punching device of the present invention, the following effects are obtained. . Since the female screw 11 for attaching the connector is embedded in the upper surface of the male mold 8, the male screw 12 of the connector 9 is removed from the male screw 12.
The male connector 8 can be attached to the connector 9 simply by screwing it into the female screw 11 for attachment.
Ki de be given, that there is no such as aching male 8. . When not in use, the male mold 8 and the female mold 7 are connected by the connecting plate 18.
Since it can be made into a single plate, it can be transported and stored.
It is convenient for . Because claimed in type structure of claim 2 of the paper punching device, and a structure for attaching an auxiliary bracket 20 to the opening 6 of the female die 7, the female
Cut the male mold 8 leaving a narrow partitioning projection in the gap 14 of the mold 7.
If you try to remove it, there is no space to leave the protrusion
Even if you can't make female 7 and male 8
Even in such a case, attach the auxiliary metal fitting 20 to the female die 7
By using the auxiliary plate portion 20a as a partitioning projection, the female mold 7
And the male mold 8 can be manufactured.
