A kind of concave-convex die cutting one-time-shaped mould
Technical field
The present invention relates to paper products printing postchannel process wrapping tool, particularly relate to a kind of concave-convex die cutting one-time-shaped mould.
Background technology
Belling is an important process of packaging post-press finishing operation, is a kind of method for stamping without printing-ink, and the concave template adopting picture group literary composition negative and positive corresponding and convex template, be placed in stock therebetween.The concavo-convex picture and text of relief-type are extruded by applying larger pressure.This method is used for the post-press finishing of printed matter and paper container, as for packagings such as trade mark, tobacco bale, carton, New Year card, labels, make it to obtain third dimension vividly attractive in appearance, belling technique uses the proper stereovision that can increase printed patterns, and plays a part crucial touch to packaging product.
Concavo-convex and the cross cutting of traditional mould can not carry out simultaneously, two operations must be divided into carry out, existing market can complete concave-convex die cutting in unified operation, belling pattern and line ball distance be greater than 5mm, if the distance of pattern and line ball is less than 5mm, the one-time formed technique of existing concave-convex die cutting can cause paper easily to be sprained because of the restriction of the height of punch and base plate, damage, also blade in die cutting process can be caused to damage the quality of deformation effect product die cutting because of highly too high, easily fluffing is produced in die cutting procedure, the phenomenons such as quick-fried line, product percent defective is caused to increase, production cost improves, production efficiency declines.Therefore, be necessary to carry out structure improvement to this mould, to overcome above-mentioned defect.
Summary of the invention
The object of this invention is to provide a kind of concave-convex die cutting one-time-shaped mould, to improve the quality of products, reduce spoilage, reduce costs, enhance productivity.
The technical scheme that the present invention adopts for its technical problem of solution is,
A kind of concave-convex die cutting one-time-shaped mould, comprises base plate and convex template, has mounting groove in base plate, convex template is located on base plate by this mounting groove, the bottom of convex template is arranged in mounting groove, and its top is stretched out from mounting groove, and the depiction of convex template is positioned at its top;
In mounting groove, there is bonded adhesives, be fixed in mounting groove by this bonded adhesives bottom convex template;
In one embodiment of the invention, the degree of depth of mounting groove is 0.7mm, and the height of convex template is 0.8mm, make the difference in height of convex template top and base plate only have 0.1mm, make convex template and bottom plate heights drop little, more steady when two procedures is carried out simultaneously, cross cutting effect is better, and paper damages little;
Convex template surrounding has draw-in groove, and convex template surrounding is connected with base plate by this draw-in groove, thus reduces the distance of convex template and the edge of a knife, and can guarantee mould-cutting precision, picture and text concave-convex effect is better.
The invention has the advantages that; this mould can prevent because height limitation causes paper to sprain; reduce height fall, make mould more steady in concavo-convex, die cutting process, effect quality is better; cross cutting blade can be protected simultaneously; prevent distortion, thus save cost, increase work efficiency; the solution of distance restriction can meet the requirement of more meticulous, the accurate packaging of product, the picture and text fineness degree of improving product.
Accompanying drawing explanation
Fig. 1 is the structural representation of the concave-convex die cutting one-time-shaped mould that the present invention proposes.
Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with diagram and specific embodiment, setting forth the present invention further.
As shown in Figure 1, the concave-convex die cutting one-time-shaped mould that the present invention proposes comprises base plate 1 and convex template 2, in base plate 1, there is mounting groove, convex template 2 is located on base plate 1 by this mounting groove, the bottom of convex template 2 is arranged in mounting groove, its top is stretched out from mounting groove, and the depiction of convex template 2 is positioned at its top;
In mounting groove, there is bonded adhesives, be fixed in mounting groove by this bonded adhesives bottom convex template 2;
In one embodiment of the invention, the degree of depth of mounting groove is 0.7mm, the height of convex template 2 is 0.8mm, the difference in height of convex template 2 top and base plate 1 is made to only have 0.1mm, make convex template 2 and base plate 1 height fall little, more steady when two procedures is carried out simultaneously, cross cutting effect is better, and paper damages little;
Convex template 2 surrounding has draw-in groove, and convex template 2 surrounding is connected with base plate 1 by this draw-in groove, thus reduces the distance of convex template 2 and the edge of a knife, and can guarantee mould-cutting precision, picture and text concave-convex effect is better.
This mould can prevent because height limitation causes paper to sprain; reduce height fall; make mould more steady in concavo-convex, die cutting process; effect quality is better, can protect cross cutting blade simultaneously, prevent distortion; thus saving cost; increase work efficiency, the solution of distance restriction can meet the requirement of more meticulous, the accurate packaging of product, the picture and text fineness degree of improving product.
More than show and describe general principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
