Abstract

(57) [Problem] To provide a mold device with improved productivity without damaging an upper mold portion. SOLUTION: After a guide post 61 is inserted between an upper mold part and a lower mold part and positioned at a predetermined position, the guide post 61 is removed and a punching material is punched. Since the guide post 61 is detached, the productivity is improved without damaging the upper mold part.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of positioning a die apparatus for punching various punched materials into a predetermined shape and a die apparatus.

[0002]

2. Description of the Related Art A conventional mold apparatus will be described below with reference to the drawings.

FIG. 2 is a sectional view of a main part of a conventional mold apparatus. In a conventional mold apparatus, an upper mold part 2 having at least a punch 1 is moved downward, and a lower mold having at least a cutting blade part 3 that pierces by punching a punching material (not shown in this drawing). A punching material (not shown in this drawing) was punched out by the mold portion 4.

[0004]

Here, the upper mold part 2 and the lower mold part 4 protrude from the lower mold part 4 and are inserted and supported in guide holes 5 provided in the upper mold part 2. During operation by the guide post 6, the regulation is always performed.
Since the guide hole 5 and the guide post 6 are always slid, there is a problem that if seizure or the like occurs in the sliding portion, the upper mold portion is damaged and productivity is deteriorated.

An object of the present invention is to solve the above-mentioned conventional problems and to provide a mold apparatus with improved productivity.

[0006]

According to the present invention, a guide post is inserted between an upper mold portion and a lower mold portion and positioned at a predetermined position. The punching material is punched out.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION
An upper mold part and a lower mold part are provided, and the upper mold part and the lower mold part are inserted into a predetermined position by inserting a guide post between the upper mold part and the lower mold part. After the guide post is removed, the punching material is punched by bringing the upper mold portion close to the lower mold portion, and the guide post is removed during the punching operation. This has the effect of not damaging the mold.

According to a second aspect of the present invention, the positioning of the upper mold portion and the lower mold portion is performed by inserting a guide post into a guide hole of a punch holder provided in the upper mold portion. In addition, the positioning is performed by removably inserting and positioning the die into the die holder of the lower mold portion, and has an effect of improving the detachability of the guide post.

According to a third aspect of the present invention, there is provided an upper mold portion having at least a punch, a lower mold portion having a cutting blade portion for inserting a punch of the upper mold portion and punching a punched material.
A guide post provided between the lower mold portion and the upper mold portion. The guide post is inserted into a guide hole of a punch holder provided in the upper mold portion, and the lower mold portion is The upper mold part and the lower mold part are removably inserted into the die holders of the parts to position the upper mold part and the lower mold part at predetermined positions, and have an effect of improving productivity.

Hereinafter, a mold apparatus according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view of a main part of a mold apparatus according to an embodiment of the present invention. In the figure, reference numeral 21 denotes a press machine ram, which is provided to be vertically movable. A punch holder 22 is provided on the lower surface of the press machine ram 21 and is fixed and provided by a punch holder fixing member 23 such as a bolt. The punch holder 22 has a plurality of guide holes 24.
have. A punch plate 26 for holding a punch 25 projecting downward is provided at a substantially central portion of the lower surface of the punch holder 22. At least the punch plate 26, the punch 25 and the punch holder 2
2 form an upper mold part.

A die 31 is provided below the upper mold part, and a cutting part 32 for punching out a press material (not shown in this drawing) by pushing a punch 25 into the die 31 and connecting to the cutting part 32. And a die discharge hole 33 through which a punch residue (not shown in this drawing) generated after punching the press material is provided. A die holder 41 is provided on the lower surface of the die 31, and a die holder discharge hole 42 connected to the die discharge hole 33 of the die 31 is provided inside the die holder 41.
It has. These die holder 41 and die 31
Thus, the lower mold part is configured.

A press machine bolster 51 is provided on the lower surface of the die holder 41 of the lower mold part, and is fixed and provided by a die holder fixing member 53 such as a bolt penetrating the die holder 41 through the block 52 of the die holder 41. I have. The press machine bolster 51 has a press machine bolster discharge hole 54 connected to the die holder discharge hole 42 of the die holder 41 inside.

Further, the upper mold part and the lower mold part are positioned by the guide post 61, and the guide post 61
Is detachably provided between the die holder 41 of the lower mold part and the block 52 and the guide hole 24 of the punch holder 22 of the upper mold part. This guide post 61
Are fixed by guide post fixing members 62 such as bolts provided through the side surface of the die holder 41.

The operation of the thus configured mold apparatus will be described below. First, the guide post 61 is inserted into the guide hole 2 of the punch holder 22 so that the tip of the punch 25 slides through the cut portion 32 of the die 31.
4 Then, the punch holder fixing member 2 is used to fix the punch holder 22 to the press machine ram 21.
3. In order to fix the die holder 41 to the press machine bolster 51, the die holder 41 is fixed to the block 52 by the die holder fixing member 53 and the guide post fixing member 62 to fix the guide post 61 to the die holder 41.

Next, as shown in FIG. 1, the press machine ram 21 is raised to stop at a position where the upper end of the guide post 61 is pulled out by the guide hole 24, and the tightening of the guide post fixing member 62 is released. Then, the guide post 61 is removed from the guide post 61 of the die holder 41.

Thereafter, the punching material is sequentially supplied to the upper surface of the die 31 and the press machine ram 21 and the press machine bolster 51 are driven up and down so that the tip of the punch 25 penetrates through the cutout portion 32 of the die 31. It slides and punches the punched material into a desired shape.

[0018]

As described above, according to the present invention, the guide post is inserted between the upper mold portion and the lower mold portion so that the upper mold portion and the lower mold portion are relatively positioned so as to be at a predetermined position. After the guide post is removed, the punching material is punched by bringing the upper mold part close to the lower mold part, and the guide post and upper metal are removed by removing the guide post during the punching operation. Since there is no sliding portion with the mold portion, there is an effect that it is possible to provide a method of positioning the mold device which does not damage the upper mold portion and improves productivity.

The positioning of the upper mold part and the lower mold part is performed by inserting the guide post into the guide hole of the punch holder provided in the upper mold part and detachably inserting the guide post into the die holder of the lower mold part. Since the positioning of the guide post to the upper die and the lower die is improved, it is possible to provide a method of positioning a die apparatus that further improves productivity.

Further, the guide post is inserted into the guide hole of the punch holder provided in the upper mold part, and is also detachably inserted into the die holder of the lower mold part, so that the upper mold part and the lower mold part are separated. Since the positioning is performed at a predetermined position, it is possible to provide a method of positioning a mold device that improves productivity.
