Description

A die-cutting structure combining die-cutting and debossing processes for upper and lower lid boxes

technical field

The invention relates to the field of packaging boxes, in particular to a die-cutting structure for combining die-cutting and embossing processes of upper and lower lid boxes.

Background technique

At present, the structure of hardcover boxes with upper and lower covers in the market is double gray boards and then a layer of outer wrapping paper, because the four corners of the outer wrapping paper have a flap structure, resulting in an extra layer of paper wrapped at the four corners, resulting in the four corners of the hardcover box being larger than the surrounding area. It is protruding, it is not beautiful after molding, and it also affects the sliding effect. At the same time, if the structure of the flap is canceled, it will cause dust leakage at the four corners, which is even more unsightly. The current solution is to die-cut the gray board first, and then click on the gray board Concave, the thickness of a layer of outer wrapping paper is left on the gray board, but because of the need to go to the die-cutting machine twice, the efficiency cannot be improved, and the defective rate is also increased; so there is an urgent need for a combination of die-cutting and dent-making processes. Cutting die structure improves production efficiency and reduces defective rate.

Contents of the invention

In order to solve the above-mentioned technical problems, the present invention provides a die-cutting and dent-cutting process combined die-cutting and dent-cutting process for the upper and lower lid boxes, which combines the two processes into one without repeating the machine. Improve production efficiency and reduce defective rate.

The technical solution adopted by the present invention to solve the technical problem is: a die-cutting structure for upper and lower cover boxes, and a die-cutting process combined, which includes a die-cutting substrate; Cutting knife and half-cutting knife; The concave iron block is also installed on the base plate of the knife mold; The concave iron block is installed on the inner side of the cutting knife respectively, and the half-breaking knife is connected with the cutting knife and the concave iron block .

A fixed iron block is also installed on the base plate of the knife mold; the fixed iron block is installed on the outside of the cutting knife and corresponds to the concave iron block, which is used to prevent the concave iron block from moving and extruding the cutting knife during die cutting. offset.

There is a drop in height between the half-cutting knife and the cutting knife, and the height of the drop is adjusted according to the thickness of the wrapping paper.

The area of the dented iron block is consistent with the position where the product needs to be dented.

Beneficial effects of the present invention: the die-cutting and dent-cutting process of the present invention combines the two processes of die-cutting and dent-indentation into one, without repeating the machine, improving the Improve production efficiency and reduce defect rate; reduce the number of paper loading, save material costs and reduce costs; avoid quality problems caused by low accuracy of dent position caused by repeated machine loading.

Description of drawings

Fig. 1 is a schematic diagram of a die-cutting and concave-cutting process integrated for upper and lower lid boxes according to an embodiment.

Detailed ways

In order to deepen the understanding of the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, which are only used to explain the present invention and do not limit the protection scope of the present invention.

Example

As shown in Fig. 1, the present embodiment provides a kind of die-cutting for the upper and lower cover box, the die-cutting structure of punching process integration, and it comprises die-cutting substrate 3; The cutting knife 5 and the half-broken knife 4 of cutting; The concave iron block 2 is also installed on the described knife mold base plate 3; The knife is connected to the concave iron block 2; a fixed iron block 1 is also installed on the knife mold substrate 3; the fixed iron block 1 is installed on the outside of the cutting knife 5 and corresponds to the concave iron block 2, for preventing When die-cutting, the concave iron block 2 moves and extrudes the cutting knife 5 to cause offset; the height of the half-broken knife 4 and the cutting knife 5 has a drop, and the height of the drop is adjusted according to the thickness of the outer wrapping paper; the concave iron block 2 The area of the product is consistent with the position where the product needs to be recessed; the base plate of the knife mold is made of wood.

In this embodiment, a die-cutting and concave-cutting die-cutting structure for the upper and lower lid boxes is used. The drop height between the half-breaking knife 4 and the cutting knife 5 is about 1/2 of the thickness of the material.

In this embodiment, a die-cutting and concave-cutting die-cutting structure for the upper and lower cover boxes is used. Taking the gray board of the lower cover of the hardcover box of the mobile phone as an example, when making the die-cutting die, a laser knife is used on the base plate of the die-cutting die Burn the cutting knife line and half-broken knife line, and burn holes of appropriate size at the positions where the fixed iron block and the concave iron block need to be installed; the second step is to install the cutting knife, crimping knife, fixed iron block and striking iron block. Concave iron block, as shown in Figure 1; install the finished mold on the die-cutting machine, when the tooth row sends the gray plate under the mold, the mold moves downward, due to the effect of pressure and the mold, the gray The board is cut, and the surface of the gray board of the lower cover is dented, just leaving a gap for a piece of paper.

In this embodiment, a die-cutting and dent-cutting process combined die-cutting and dent-cutting process for the upper and lower lid boxes is combined into one process, which does not need to be repeated on the machine, improves production efficiency, and reduces Defective rate; the number of papers is reduced, which saves material costs and reduces costs; avoids quality problems caused by low accuracy of the indentation position caused by repeated machine loading.

The above embodiments shall not limit the present invention in any way, and all technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
