As used herein, the word "comprising" and similar words are intended to mean that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items.

Aiming at the problems in the prior art, the embodiment of the utility model provides a three-in-one die cutting die.

Examples

As shown in fig. 9-10, a three-in-one die cutting die comprises an upper template and a lower template, wherein three groups of cutting dies are arranged on the upper template in parallel; the first group of cutting dies consists of an inner hole cutting edge 3 and a guide hole punching cutting edge 4 from left to right along the horizontal direction; the second group of cutting dies consists of handle cutting edges 5 and first guide posts 6; the third group of cutting dies consists of a product tearing knife edge 7 and a second guide post 8; the guide hole punching blade 4, the first guide post 6 and the second guide post 8 correspond to each other; the guide hole punching blade 4 can punch a guide hole on the die-cutting material; the first guide post 6 and the second guide post 8 can be sleeved in the guide hole; the distance between the guide hole punching blade 4 and the first guide post 6 is the same as the distance between the first guide post 6 and the second guide post 8.

When the die-cutting device is used, a die-cutting material passes through the space between the upper template and the lower template and moves at a certain speed, the upper template approaches to the lower template and performs primary die-cutting on the die-cutting material, and the shape corresponding to the blade is punched; during secondary punching, the initial material moves to the position below the first group of cutting dies, and the punched shape of the first group of cutting dies moves to the position below the second group of cutting dies; the shape punched by the second group of cutting dies is moved to the position below the third group of cutting dies; punching again; and the die cutting material moves again, and the shapes punched by the first group of cutting dies and the second group of cutting dies move to the lower part of the third group of cutting dies to finish third punching to obtain the final product shape. Repeating the above steps can obtain continuous products.

The number of the inner hole cutting edges 3 is 4, and the 4 inner hole cutting edges 3 are distributed in two rows and two columns of rectangular arrays; the two rows of inner hole blades 3 are symmetrical to each other. The two rows are mainly considered in the size of the upper template and the space of the machine, and can be arranged in multiple rows without being influenced.

The three guide hole punching blades 4 are respectively a guide hole punching blade I4-1, a guide hole punching blade II 4-2 and a guide hole punching blade III 4-3; the first guide hole punching blade 4-1 is positioned on the upper side of the inner hole blade 3, and the second guide hole punching blade 4-2 and the third guide hole punching blade 4-3 are positioned on the lower side of the inner hole blade 3 and positioned on a horizontal line. The guide hole punching blade I4-1 is positioned in the middle of the two rows of inner hole blades 3; the second guide hole punching blade 4-2 and the third guide hole punching blade 4-3 are respectively positioned right below the two rows of inner hole blades 3.

The number of the handle cutting edges 5 is 4, the 4 handle cutting edges 5 are symmetrical in pairs, and the two handle cutting edges 5 on the same side are connected through a connecting cutting edge 9; the two handle blades 5 at the same side are provided with extension blades 10 at the side far away from each other. The connecting blade 9 and the extending blade 10 are arranged to facilitate discharging waste materials which are not needed after die cutting, for example, when the connecting blade 9 is not arranged, the waste materials punched by the inner hole blade 3 are in a square hole, and are not easy to be separated due to large adsorption force; and the connecting blade 9 is arranged to cut off the space between two adjacent square holes, so that the adsorption force is much smaller and the square holes are easy to separate. Similarly, the integrity of the square hole can be damaged by prolonging the cutting edge, and the adsorption force is reduced.

Although the embodiments of the present invention have been described in detail hereinabove, it is apparent to those skilled in the art that various modifications and variations can be made to the embodiments. However, it is to be understood that such modifications and variations are within the scope and spirit of the present invention as set forth in the following claims. Moreover, the utility model as described herein is capable of other embodiments and of being practiced or of being carried out in various ways.
