A concave-convex texture mold and its manufacturing method and application

Abstract

The invention discloses a mold with concave-convex texture and its manufacturing method and application. The surface of the mold with concave-convex texture is provided with concave-convex texture, and the mold surface is a flat surface or a regular curved surface or a concave-convex relief surface; the concave-convex texture The reason is that several notches with different lengths, depths, widths, splines, transitional structures, and bottom structures are formed according to the set shape and position relationship; the manufacturing method of the concave-convex texture mold includes the following steps: Step S1: Design point-line diagram and carry out three-dimensional relief modeling; step S2: process the surface on the mold according to the three-dimensional relief model; step S3: use the mechanical engraving machine to select the engraving knife according to the point line pattern, set the parameters, and mechanically carve the length on the surface , Depth, width, spline, transition structure, bottom structure are not exactly the same number of nicks; get concave-convex texture mold. The invention combines embossed modeling and engraved gravure, so that the embossed dot line pattern formed by embossing on the surface of the metal product is finer and more three-dimensional.

Description

technical field [0001] The invention relates to the technical field of gravure printing molds, in particular to a concave-convex texture mold and its manufacturing method and application. Background technique [0002] On traditional banknotes, the intaglio pattern formed by gravure printing is often used to represent the main scene images such as characters, landscapes, buildings, etc. The intaglio pattern is an important part of the banknote and an anti-counterfeiting method. [0003] In gravure printing, the gravure is first engraved, and then the surface of the gravure is covered with ink, and then the ink in the indentation of the gravure is transferred to the carrier, so that the ink on the carrier forms an intaglio pattern to reproduce the pattern on the intaglio. Gravure printing is essentially a flat printing method. The printed gravure pattern only expresses three-dimensional space through the thickness and shape relationship of dots and lines.

Problems solved by technology

[0008] In view of the defects in the prior art that the gravure pattern is fine but the three-dimensional effect is not good, the relief pattern is good but the three-dimensional effect is not fine enough, and the embossed pattern is not full, the purpose of the present invention is to provide a concave-convex texture mold, the production of the concave-convex texture mold method and the application of the concave-convex texture mold, combined with the two major technologies of engraving intaglio design and relief mold making, through embossing and transfer on the surface of the metal product to form a fine, three-dimensional effect, and full-bodied embossed dot-line pattern. Improve the artistic expression of metal products such as metal foil, coins, and badges
