Manufacturing method of imprinting mold

Abstract

The invention provides a manufacturing method of an imprinting mold. The method comprises the following steps of 1) manufacturing a mother set structure, and forming a plurality of first groove structures on the surface of the mother set structure; 2) manufacturing a transfer printing template based on the mother set structure, wherein a plurality of convex structures are formed on the surface ofthe transfer printing template; 3) providing an imprinting mold substrate; 4) forming an imprinting mold flexible material layer on the surface of the imprinting mold substrate; 5) forming a pluralityof second groove structures on the surface of the flexible material layer of the imprinting mold by adopting an imprinting process based on the transfer template; 6) curing the imprinting mold flexible material layer; 7) peeling the transfer template. According to the manufacturing method of the imprinting mold, the utilization rate of the mother set structure can be increased, the manufacturingprocess is simple, the stress in the imprinting mold is smaller, and the risk of bursting does not exist.

Description

technical field [0001] The invention belongs to the technical field of embossing technology, and in particular relates to a method for making an embossing mold. Background technique [0002] In the prior art, imprinting generally adopts a hard mold, and the imprinting mold is generally a metal mold, such as a typical nickel (Ni) mold. However, metal molds have the following problems: first, metal molds have a lifetime, and must be scrapped if they are defective. The imprinted products that can be produced by a metal mold are limited, and the utilization rate is low; second, the manufacturing process of metal molds It is complicated and costly, which is not conducive to mass production; third, metal molds generally need to be covered on the cylinder for embossing operations, and multiple metal molds need to be spliced ​​on the periphery of the cylinder, so that the adjacent metal molds There will be a splicing seam, and since both sides of the splicing seam are metal, when u...

AI Technical Summary

Problems solved by technology

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a method for making an embossing mold, which is used to solve the problem that a metal mold in the prior art can produce limited products and low utilization rate; The preparation process of the metal mold is complicated and the cost is high, which is not conducive to mass production; the metal mold generally needs to be covered on the cylinder for embossing work, and multiple metal molds need to be spliced ​​on the periphery of the cylinder, so that the adjacent metal molds There will be a stitching seam between them, and the position of the stitching seam is metal on both sides. When using tape to bond the metal molds on both sides of the stitching seam, the stress is very large. It is easy to cause bursting, which leads to the scrapping of metal molds and other problems
