題点がなお残っていた。Technical background of the invention One of the manufacturing methods for cutting dies used to cut adhesive tapes such as labels or markers into predetermined shapes is to cut patterns on steel plates such as low carbon steel. There is a known method of manufacturing a cutting die having a punching pattern of a predetermined shape by forming a resist film and performing an etching process. If the etching process is performed only once when manufacturing such a cutting die, there are problems such as not being able to obtain a tall blade or not having a sharp cutting edge. In order to solve the above-mentioned problems, a method of manufacturing cutting dies using two-stage etching has been proposed (Japanese Patent Publication No. 52-10000, Japanese Patent Publication No. 57-2).
7938, JP-A-63-105980, etc.)
. In the method for manufacturing a cutting die using two-stage etching,
A resist film corresponding to the punched pattern is formed on a steel plate, an etching process is performed to form a convex part, the resist film remaining on the top of the convex part is removed, and an etching process is performed again to form a convex part. Cutting dies are manufactured by processing into a sharp blade shape. However, in such a two-stage etching method, when etching is performed again, the sides of the convex portion are likely to be etched (side etching), making it impossible to obtain a desired bottom edge width, and in the case of excessive etching. Problems still remained, such as the part becoming thinner and breaking, resulting in the blade being either too high or too low.

がら具体的に説明する。DETAILED DESCRIPTION OF THE INVENTION Hereinafter, a method for manufacturing a cutting die according to the present invention will be specifically described with reference to the drawings.

脂板等で補強して使用することもできる。In the present invention, first, a resist film 2 corresponding to the contour shape of the label to be manufactured is created on a steel plate l (Fig. 1).
. As the steel plate 1, metals such as carbon steel and stainless steel can be used without particular limitation. The thickness of the steel plate is not particularly limited, but when the cutting die is used by attaching it to a roller, it is preferable that it has appropriate flexibility, and when it is used as a flatbed cutter, it is preferable that it has appropriate rigidity. . When used as a flatbed cutter, it can be reinforced with a metal plate or synthetic resin plate having appropriate rigidity.

の巾は、後に抜き型の刃の巾となるが、通常１００〜１
０００μｍ程度であり、用途により任意に選択できる。In order to form the resist film 2 on the steel plate 1, various conventionally known film forming methods can be employed. Also, resist film 2
The width will later become the width of the cutting die blade, but it is usually 100 to 1
000 μm, and can be arbitrarily selected depending on the application.

レジスト膜２の巾との関連により、通常７０〜９００μ
ｍ程度である。Next, the steel plate 1 on which the resist film 2 has been formed is subjected to an etching process (first etching step) to form convex portions 3 of a predetermined height at the locations where the resist film 2 has been formed (FIG. 2).
. As the etching solution, various conventionally known etching solutions such as ferric chloride, hydrochloric acid, nitric acid, or mixtures thereof can be used. Although the etching time varies depending on the type of etching solution, it is usually 20 to 120 minutes, and the height of the convex portion 3 formed by the etching process is usually 70 to 900 μm depending on the width of the resist film 2.
It is about m.
次いて、形成される刃部の形状に対応して凸部３か形成
された鋼板ｌの全面にレジスト膜４を作成するが、また
は少なくとも凸部３側面を覆うようにレジスト膜４を作
成する（第３ａ図または第３ｂ図）。Next, a resist film 4 is created on the entire surface of the steel plate l on which the protrusions 3 are formed in accordance with the shape of the blade to be formed, or at least the resist film 4 is created so as to cover the sides of the protrusions 3. (Figure 3a or 3b).

（第４ｂ図）。After creating the resist film 4, the resist film 2.4 at least on both ends of the top of the convex portion 3 is removed using a grinder or the like. When removing the resist film 2.4, only the resist film at both ends of the top may be removed as shown in FIG. 4a, or the resist film at the top and both ends of the top may be removed (FIG. 4b).
凸部３はその側面部分がレジスト膜４により保護されて
いるので、サイドエツチングを防止でき、任意の底部刃
のを有する背の高い刃が得られる。Since the side surfaces of the convex portions 3 are protected by the resist film 4, side etching can be prevented and a tall blade having an arbitrary bottom edge can be obtained.

である。In addition, when removing the resist film 2.4, in one cutting die, there are two areas where only the resist film 2.4 at both ends of the top is removed (as shown in FIG. 4a), and a location where only the resist film 2.4 at both ends of the top is removed. It is undesirable that the portions where .4 has been removed (as shown in Figure 4b) are mixed. In other words, only the portion not protected by the resist film 2.4 or the second
Since the resist film 2.4 is etched in the etching process, if there are places where only the resist film 2.4 on both ends of the top part is removed and places where the resist film 2.4 on the top part and both ends of the top part is removed, it may be formed. This is because the heights of the blades are not the same, and when cutting labels, etc., it may not be possible to cut to a uniform depth.
次いで、凸部３の少なくとも頂部両端のレジスト膜２．
４が除去された鋼板にエツチング処理を施し、刃部を形

を除去し、鋼板を洗浄して抜き型が得られる。Next, a resist film 2. is applied to at least both ends of the top portion of the convex portion 3.
The steel plate from which No. 4 has been removed is subjected to etching treatment to form a blade portion (second etching step) (Fig. 5a or 5b).
(shown in figure). After the second etching process, resist film 2.4
is removed and the steel plate is cleaned to obtain a cutting die.

。In the second etching step, as in the first etching step described above, various conventionally known etching solutions can be used. The etching time varies depending on the type of etching solution, but is usually 2 to 10 minutes. In this second etching step, the vicinity of the top of the removed resist film 2.4 is etched, so that a cutting die with a sharp cutting edge, a rough bottom edge, and a tall cutting edge is obtained.

シャープである。The height of the cutting die blade thus obtained is 70 to 900μ.
It is about m. The cutting die according to the present invention has a sufficient bottom blade, a sufficient blade height, and a sharp cutting edge, so it is durable, has little wear, and has a sharp cutting edge.

This makes it possible to manufacture cutting dies that have a sufficient blade height and a sharp cutting edge, are durable, have little wear, and are sharp.
