Adjustable die-cutting die

Abstract

The invention provides an adjustable die-cutting die which comprises a pair of die plates matched with each other, wherein the die plates are provided with a group of die-cutting cutters; each die plate comprises a plurality of die blocks; the die blocks are sequentially arrayed; adjustable connecting structures are arranged among the die blocks, and connect the adjacent die blocks to form the die plates; gaps are reserved among the adjacent die blocks; the sizes of the gaps are changed by the adjustable connecting structures; the adjustable structures comprise locating holes located in the die blocks and studs arranged in the locating holes; the two ends of the studs extend into the locating holes of the adjacent die blocks respectively to connect the die blocks; adjustable holes are formed in the die blocks, and exposed out of the outer surfaces of the die blocks; the insides of the adjustable holes are communicated with the locating holes; and the studs in the locating holes are adjusted by the adjustable holes. In a production process, if the dimension of paper deforms, the adjustable tool extends into the adjustable holes to adjust the studs, so that the sizes of the die plates are changed, and refabrication of the die due to dimension change of the paper is not required.

Description

technical field [0001] The invention relates to a die-cutting tool, in particular to an adjustable die-cutting die. Background technique [0002] At present, the die-cutting mold adopts integral and full-page die-cutting, and the paper has a texture of horizontal and vertical lines. The horizontal lines are easily affected by temperature and humidity, and the size changes greatly, resulting in inaccurate product printing registration during the die-cutting process, so the mold will be damaged. It needs to be redone due to the change of paper. However, the cost of the overall full-plate steel mold is high. Once the size changes, it is required to replace it according to the new panel size, which will result in higher cost and longer production cycle. At the same time, the stability of the product is not enough, and the work efficiency is low. The existing full-page molds have poor flexibility when dealing with changes in the external environment of the paper and cannot solve...

AI Technical Summary

Problems solved by technology

[0002] At present, the die-cutting mold adopts integral and full-page die-cutting, and the paper has a texture of horizontal and vertical lines. The horizontal lines are easily affected by temperature and humidity, and the size changes greatly, resulting in inaccurate product printing registration during the die-cutting process, so the mold will be damaged. To be redone due to paper changes

However, the cost of the overall full-plate steel mold is relatively high. Once the size changes, it is required to replace it according to the new panel size, which will result in higher costs and longer production cycles. At the same time, the stability of the product is not enough and the work efficiency is low.

The existing full-page molds have poor flexibility when dealing with changes in the external environment of the paper and cannot solve such drawbacks

[0003] The traditional mold is fixed and cannot be adjusted and replaced locally. If the size needs to be adjusted and changed, the entire mold can only be scrapped and replaced. The cost is high, the production cycle is long, and the efficiency is low, which is not conducive to improving production efficiency. Therefore, it is necessary to adjust the mold The structure of the cutting die is improved
