Description

Rolling die manufacturing method

The invention relates to a method for manufacturing a printing die, in particular to a roller which can be manufactured in a simple, quick and convenient manner, and which has more practical and effective characteristics in its overall application. Innovative designer of the manufacturing method of printing molds.

According to the general method for making an embossing roller, the method can be roughly divided into two types, one is a turning type manufacturing method, and the other is a nickel film covering type manufacturing method; wherein:

The turning method is mainly used to clamp a circular work piece on a precision lathe, and after it is rotated, it is simple to engrave on the work piece with a harder tool [such as a tungsten steel turning tool or a diamond turning tool]. The graphics; however, the turning method can achieve the advantages of seamless joints in the operation, but because of the change of the graphics, the rotation direction and the feeding direction of the lathe are limited, and only simple lines or It is a curve.

The nickel film coating method is mainly for forming a pattern structure on a soft substrate [such as rubber or polymer material], and then depositing nickel metal on the surface of the soft substrate by chemical deposition. After the film is removed, the surface of the nickel film is coated on the surface of the metal roller to obtain an embossing roller; however, the nickel film coating method is a type of overturning, so the graphic operation is performed on the operation. The complexity is not limited, but it will leave seams during the coating process, and it will not reach the seamless roller.

In view of this, the inventor has been in the process of researching and improving the existing structure and defects by providing rich experience in design and development and actual production of the relevant industries for many years, and to provide a manufacturing method for the printing die, in order to achieve better practical value. Target person.

c. Exposure development: Please refer to the third figure for the manufacturing step (2) of the present invention. In order to make the pattern reach the seamless type, the exposure is performed by rotating the hollow cylinder (1) in an angular step. The hollow cylinder (1) is mounted on a rotating mechanism, and the exposure is controlled by controlling the rotation angle. First, the hollow cylinder (1) is divided into an angle which can be diverged by 360 degrees on the circumference, and then exposed at each angle of rotation. After each set of exposure time, continue this angle for the next exposure, and so on, and finally the angle can be fully connected back at 360 degrees to achieve no seams, and the exposure will be parallel. The exposure source of the ultraviolet light is introduced into the hollow cylinder for exposure, or the exposure source of the ultraviolet LED and the ultraviolet cold cathode tube is introduced into the hollow cylinder for exposure, and in order to make the pattern more complete, the plastic can be used. The photomask (4) is such that the distance between the photomask (4) and the substrate (3) on the curved surface of the inner edge of the hollow cylinder (1) is relatively close, or a glass mask is used ( ) or metal etching mask (4), and finally developed, to obtain a pattern with a seamless microstructure on the substrate (3) of the inner edge of the hollow cylinder (1) (please refer to the fourth figure together) The manufacturing step (3) of the present invention is as a master mold;

d. Hard baking: heating and hard-baking the substrate (3) having a pattern with a seamless microstructure at the inner edge of the hollow cylinder (1), and baking the resin component in the substrate (3) for subsequent processing;

e.翻翻:Please refer to the fifth drawing, the manufacturing steps of the present invention (4) and the sixth drawing, the manufacturing steps of the present invention (5), after the hollow cylinder (1) master mold is produced, in the hollow cylinder (1) The polymer material is directly poured into the master mold, and after being solidified, it is demolded and turned into a soft rolling mold kernel (5), or the metal is directly plated on the hollow cylinder by electroforming. On the substrate (3) in the master mold, the substrate (3) is removed, and the metal stamping mold core (5) can be obtained.

However, the above-described embodiments or drawings are not intended to limit the structure or the use of the present invention, and any suitable variations or modifications of the invention will be apparent to those skilled in the art.

From the above, the component composition and the use description of the present invention show that, compared with the prior art, the present invention mainly utilizes an internal cyclone coating method, and the inner surface of the hollow cylinder is uniformly coated on the substrate.
