Description

Technical Field

[0001] This utility model relates to the field of printing technology, specifically to a die-cutting and creasing mold for preventing sticking. Background Technology

[0002] Die-cutting machines, also known as die-cutting machines, cutting machines, or CNC punching machines, are mainly used for die-cutting (full cut, half cut), creasing, hot stamping, laminating, and automatic waste removal of various non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronic products, and mobile phone pads. They utilize steel blades, metal molds, and steel wire, applying pressure through a printing plate to cut printed materials or cardboard into specific shapes. They are essential equipment for post-printing packaging processing.

[0003] The die-cutting and creasing mold for preventing adhesion, as described in publication CN218985903U, includes a die-cutting blade plate base and a steel base film that are fitted together. The die-cutting blade plate base is embedded with die-cutting blade lines for die-cutting. Die-cutting blade lines are provided corresponding to the "ears" of the substrate to be cut, and creasing blade lines are provided inside the die-cutting blade lines for creasing the substrate. Ear-rebound adhesive is provided between the die-cutting blade lines and the creasing blade lines, and the ear-rebound adhesive can abut against the "ears" of the substrate. A second top ear-rebound adhesive is provided on the steel base film, corresponding to the ear-rebound adhesive. A spring sheet is also provided on the steel base film, and the second top ear-rebound adhesive is distributed on the outer periphery of the spring sheet. The ear-rebound adhesive, the second top ear-rebound adhesive, and the spring sheet respectively provided on the die-cutting blade plate base and the steel base film of this invention can provide a separating force at the "ears" during die-cutting without adding other structures. However, the prior art still has shortcomings:

[0004] In the existing technology, the function of the spring is to raise the middle part of the substrate when it is being die-cut, which helps the second top ear rebound adhesive to give the ear an upward rebound force. However, when the spring and the second top ear rebound adhesive raise the cardboard box, they can also easily leave marks on the cardboard box surface. Although the spring has elasticity, the hard contact can still easily damage the cardboard box surface. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the above-mentioned defects and provide a die-cutting and creasing mold that prevents sticking.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a die-cutting and creasing mold for preventing adhesion, comprising:

[0007] A base, wherein a lower mold is fixedly connected to the middle of the upper end of the base;

[0008] A top plate, which is disposed above the base;

[0009] Supporting columns are fixedly connected to the upper ends of the base on the left and right sides and front and back, and the upper ends of the supporting columns are fixedly connected to the lower end of the top plate.

[0010] Blade indentation plates are arranged above the lower die.

[0011] Lifting mechanisms are arranged at the upper end of the blade indentation plate.

[0012] Die-cutting mechanisms are arranged between the lower die and the blade indentation plate, the die-cutting mechanism comprises a die-cutting knife fixedly connected to the lower end of the blade indentation plate, the lower die is provided with a cutting groove matched with the die-cutting knife, and the two sides of the die-cuting knife are provided with rebounding strips, and the upper end of the rebounding strip is fixedly connected to the lower end of the blade indentation plate.

[0013] Indentation mechanisms are arranged between the lower die and the blade indentation plate, the indentation mechanism comprises an indentation strip fixedly connected to the lower end of the blade indentation plate, and the lower die is provided with an indentation groove matched with the indentation strip.

[0014] Separation convex strips are fixedly connected to the upper end of the lower die.

[0015] As an improvement, the lifting mechanism comprises:

[0016] Fixed seats are fixedly connected to the upper end of the blade indentation plate.

[0017] A gas cylinder is fixedly connected to the middle of the upper end of the top plate, and the lower end of the gas cylinder is fixedly connected to the middle of the upper end of the fixed seat.

[0018] As an improvement, the height of the separation convex strip is smaller than the height of the die-cutting knife.

[0019] As an improvement, the separation convex strip is arranged outside the edge rebounding strip.

[0020] Compared with the prior art, when the die-cutting knife moves downward into the cutting groove for die-cutting, the separation convex strip lifts the paperboard around the outside upward, forms a height difference between the paperboard on the two sides of the cutting position of the die-cutting knife and completely separates the paperboard, and the edge of the die-cutting does not form adhesion, and the separation convex strip is arranged outside the die plate and does not damage the required die plate.

[0034] Lower die 2 upper is provided with blade indentation plate 5, lifting mechanism 6 is set in the upper end of blade indentation plate 5, lifting mechanism 6 includes fixed seat 61, air cylinder 62, fixed seat 61 is fixedly connected in the upper end of blade indentation plate 5, air cylinder 62 is fixedly connected in the middle of top plate 3 upper end, air cylinder 62 lower end is fixedly connected in the middle of the upper end of fixed seat 61, air cylinder 62 can drive blade indentation plate 5 to move up and down and carry out die cutting to paperboard.

[0035] A die-cutting mechanism 7 is provided between the lower mold 2 and the blade creasing plate 5. The die-cutting mechanism 7 includes a die-cutting blade 71 fixedly connected to the lower end of the blade creasing plate 5. The shape of the die-cutting blade 71 is customized according to the template to be die-cut. The die-cutting blade 71 is set on the edge to be cut. The lower mold 2 is provided with a cutting groove 72 for use with the die-cutting blade 71. Rebound strips 73 are provided on both sides of the die-cutting blade 71. The upper end of the rebound strip 73 is fixedly connected to the lower end of the blade creasing plate 5. The die-cutting blade 71 moves downward to die-cut the cardboard placed on the upper end of the lower mold 2. The rebound strip 73 bounces the die-cut cardboard off the die-cutting blade 71.

[0036] The upper end of the lower mold 2 is fixedly connected with a separation ridge 9. The height of the separation ridge 9 is less than the height of the die-cutting blade 71. The separation ridge 9 is set outside the edge rebound strip 73 and outside the required die-cutting template. When the die-cutting blade 71 moves down into the cutting groove 72 for die-cutting, the separation ridge 9 lifts the outer side of the cardboard around the die-cutting edge upward, forming a height difference between the cardboard on both sides of the cutting position of the die-cutting blade 71 and thus completely separating them, without forming adhesion at the edge of the die-cutting.

[0037] A creasing mechanism 8 is provided between the lower mold 2 and the blade creasing plate 5.

[0038] In specific implementation of this utility model, such as Figures 1-10 As shown, the cardboard to be die-cut is placed above the lower mold 2. The cylinder 62 is activated to drive the blade creasing plate 5 to move downward to creasing and die-cut the cardboard. The die-cutting blade 71 moves downward to die-cut the cardboard placed on the upper end of the lower mold 2. The rebound strip 73 can bounce the die-cut cardboard off the die-cutting blade 71. When the die-cutting blade 71 moves downward to the cutting groove 72 to die-cut, the separating ridge 9 lifts the outer side of the cardboard around the die-cutting position upward, forming a height difference between the cardboard on both sides of the cutting position of the die-cutting blade 71 and thus completely separating them. There will be no adhesion at the edge of the die-cutting. Moreover, the separating ridge 9 will be set on the outside of the template and will not damage the template. At the same time, the creasing strip 81 moves downward to the creasing groove 82 to creasing the cardboard placed in the middle, completing the creasing and die-cutting of the cardboard.
