Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.
In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
In addition, in the description of the present invention, the technical solutions in the embodiments may be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory or can not be realized, the combination of the technical solutions should be considered to be absent, and is not within the protection scope of the present invention.
As shown in fig. 1-4, an embodiment of the present invention provides a mold for punching a box opening portion of a packaging box, including a lower template 10 and an upper template 20, wherein a mold core counter bore is formed in the lower template 10, a mold core 11 is embedded in the mold core counter bore, in order to facilitate accurate positioning of the upper template 20 and the lower template 10 during punching, a positioning hole 12 is formed in the center of the mold core 11, a cutter groove 13 is further formed in the mold core 11, a positioning column 21 is arranged in the center of the upper template 20, a cutter 22 adapted to the cutter groove 13 is further fixedly arranged on the upper template 20, and in order to enable a processed tear opening to be pulled open quickly without affecting the integral connection of the box opening portion on the box cover, a cutting edge of the cutter 22 is in a zigzag shape; the cutter groove 13 and the cutter 22 are both arc-shaped, tear openings processed by the arc-shaped cutter groove 13 and the cutter 22 are circular and can be opened by being directly pressed by a thumb, and the arc-shaped cutter groove 13 and the cutter 22 are matched with the structure and the shape of the thumb of a human body by combining the ergonomic design concept, so that a box body can be opened easily; in order to facilitate the connection and fixation of the upper template 20 and a punch press or a press machine, the upper template 20 is provided with bolt holes 23; in order to protect the cutting blade 22 and to allow a quick retraction, the core 11 is made of copper or a copper alloy.
In another embodiment, the cutter groove 13 and the cutter 22 are both square.
Above-mentioned scheme is when using, refer to fig. 1, fig. 2 and fig. 3, earlier fix lower bolster 10 to the workstation, then it is fixed with the press to go up template 20, accomplish location with locating hole 12 and reference column 21, the cardboard that will substitute processing during processing is placed on lower bolster 10, start press punching press cardboard, cutter 22 falls into cutter groove 13 during the punching press, cutter 22 utilizes shearing force to accomplish the punching press to the cardboard with cutter groove 13, refer to fig. 4, because the cutting edge of cutter 22 is the cockscomb structure, consequently tear the tear after the punching press is accomplished and draw mouthful and produce spaced fracture mouth, but still become connected state on the whole, when needing to open the packing carton, only need press and tear the mouth can.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein; any reference sign in a claim should not be construed as limiting the claim concerned.
