1. Field of the Invention
The present invention relates generally to embossing dies, and more particularly to an embossing die with a cutting function.
2. Description of Related Art
Embossing dies used in the handicrafts industry mainly involve imprinting certain patterns or characters on sheet materials such as paper, films, foam, soft magnets, photos, leather and cloth, or imprinting embossing patterns or characters on the surface of the sheet materials, which are generally used for fabricating cards, photo albums or packaging materials.
A conventional method for fabricating an embossing die involves etching a metal material to form a group of metal templates with patterns thereof corresponding to each other (metal templates with corresponding concave and convex portions), and adhering the two metal templates to a foldable plastic board. As such, the user only needs to fold the plastic board so as to imprint a three-dimensional embossing pattern on a piece of paper.
To use the conventional embossing die, the user puts a piece of paper on the first metal template 11a or the second metal template 11b and then folds up the first frame 10a and the second frame 10b such that the first pattern 110a and the second pattern 110b are aligned with each other and pressed against the piece of paper at the same time, thereby imprinting a three-dimensional embossing pattern on a piece of paper.
However, etching is required for forming the patterns of the first and second metal templates 11a, 11b, which is time-consuming and costly and accordingly is not suitable for industry application.
Further, a cutting step using a knife or scissors is usually needed after an embossing pattern is imprinted so as to trim the embossing pattern, which is rather time-consuming and laborious and accordingly is not suitable for industry application.
Therefore, it is imperative to provide a cutting die to overcome the above-described drawbacks of the prior art.
In view of the above drawbacks of the prior art, it is an objective of the present invention to provide a cutting die for allowing a cutting operation and the embossing operation to be concurrently performed to thereby enhance the application value of the cutting die.
Another objective of the present invention is to provide a cutting die conducive to reduction of manufacturing costs.
In order to achieve the above and other objectives, the present invention provides a cutting die comprising a first plastic template and a second plastic template detachably coupled to each other, the cutting die is characterized in that: a first pattern and a third pattern are formed on a surface of the first plastic template and a surface of the second plastic template, respectively, so as for the first pattern and the third pattern to correspond in position to each other and be foldable together, and at least one of the first pattern and the third pattern is provided with a cutting portion configured for hole-punching.
The cutting portion is a carbon steel knife, and detachably disposed on the pattern. The first plastic template is coupled to the second plastic template through a bi-directionally foldable means such that the first and second plastic templates can be bi-directionally folded relative to each other
The cutting die further comprises a first frame and a second frame that are detachably coupled to each other and have bases formed on opposite surfaces thereof so as for the first and second plastic templates to be disengageably disposed on the bases of the first and second frames, respectively. The bases are groove-shaped, and the bottom of each of the grooves is defined as an embossing surface.
The first and second frames can be coupled together through a hinge such that the first and second frames can be folded relative to each other.
The first and second plastic templates can be disengageably disposed on the bases of the first and second frames through an attracting means or an engaging means.
According to another embodiment, a second pattern is formed on another surface of the first plastic template, and a fourth pattern is formed on another surface of the second plastic template to be correspondingly assembled to the second pattern. Further, the cutting portion is formed on at least one of the second pattern and the fourth pattern.
The plastic templates of the present invention reduce the fabrication cost compared with the conventional metal templates. Further, the cutting portion of the present invention allows the cutting operation to be performed while the embossing operation is performed so as to dispense with the cutting step that is performed after the pattern is imprinted in the prior art, thereby improving the application properties of the cutting die.
The following illustrative embodiments are provided to illustrate the disclosure of the present invention, these and other advantages and effects can be apparent to those skilled in the art after reading the disclosure of this specification.
The first frame 20a has a groove-shaped first base 200a with a first embossing surface 201a defined on the bottom thereof.
The second frame 20b has a groove-shaped second base 200b with a second embossing surface 201b defined on the bottom thereof and corresponding to the first embossing surface 201a such that the second embossing surface 201b can be covered with the first embossing surface 201a.
