Abstract
The utility model discloses a combined upper-lower cutting die comprising an upper template and a lower template, wherein an outer frame cutter is fixedly arranged at one side of the upper template, which corresponds to the lower template; a full cutter and a lug cutter are arranged at one side of the outer frame cutter, which corresponds to the lower template; the full cutter is greater than the outer frame cutter in length; the lug cutter is less than the outer frame cutter in length; and a lower lug cutter is arranged at the position of the lower template, which corresponds to the lug cutter. Upper release paper and a rubber substrate are broken by punching through the outer frame cutter along an outer frame of a product, so that the full cutter breaks all of the upper release paper, the rubber substrate and lower release paper by punching; the lug cutter breaks the upper release paper at the position of a lug by punching; and bottom paper and rubber at the position of the lug can be broken by punching through a cutter below the lug. Several cutters are integrated on one mould, so that a punching process is realized by using material toughness and time difference, the production cost is effectively reduced, and the production efficiency and the product precision can be improved.
Description
Technical field
The utility model relates to mould applications, particularly a kind of cutting die that makes up up and down.
Background technology
Two-sided tape is take paper, cloth, plastic sheeting as base material, then elastomeric-type pressure sensitive adhesive or resin pressure sensitive adhesive are uniformly coated on the web-like adhesive tape of making on above-mentioned base material, is comprised of base material, adhesive, barrier paper (film) three parts.Be widely used in generally that leather, inscription plate, stationery, electronics, automobile edging are fixed, the purposes such as footwear industry, paper processed, artifacts stickup location.A kind of double faced adhesive tape with ear as illustrated in fig. 1 and 2, it is fitted successively by upper release liners A, gum base materials B and lower release liners C and forms, wherein, and the lower release liners C of the equidistant arrangement of release liners A and gum base materials B on array, release liners A protrudes gum base materials B and forms ear D outward.
Normally adopt the mode of aperture cover position bimodulus punching press in the same industry, be stamped into for the first time and get rid of the ear part, be stamped into for the second time and get rid of the product housing, but so not only to take two punch presses, be equipped with two molds, and material has enough to meet the need between two punch presses, causes that production efficiency is low, the precision of product is low.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of cutting die that makes up up and down, to realize reducing production costs, to enhance productivity and the purpose of Product Precision.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of cutting die that makes up up and down, comprise cope match-plate pattern and lower bolster, one side of the corresponding described lower bolster of described cope match-plate pattern is installed with the housing cutting knife, one side of the corresponding described lower bolster of described housing cutting knife is provided with complete disconnected cutting knife and ear cutting knife, the length of described complete disconnected cutting knife is greater than the length of described housing cutting knife, and the length of described ear cutting knife is less than the length of described housing cutting knife; The corresponding described ear cutter of described lower bolster is provided with the ear lower cutter.
Preferably, be provided with pilot pin on described cope match-plate pattern, the corresponding described pilot pin of described lower bolster place is provided with locating hole.
Pass through technique scheme, the cutting die of combination up and down that the utility model provides, upper release liners and gum base materials are thrust along the product housing by the housing cutting knife, complete disconnected cutting knife all thrusts upper release liners, gum base materials and lower release liners, the ear cutting knife thrusts release liners in the ear place, and the ear lower cutter thrusts ear place's base stock and glue.Several cutters are integrated on a secondary mould, utilize the toughness of material and time difference to realize punching press, effectively reduced production cost, improved production efficiency and Product Precision.

The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
The utility model provides a kind of cutting die (referring to Fig. 3 to 5) that makes up up and down, comprise cope match-plate pattern 11 and lower bolster 12, one side of the corresponding lower bolster 12 of cope match-plate pattern 11 is installed with housing cutting knife 13, one side of the corresponding lower bolster 12 of housing cutting knife 13 is provided with complete disconnected cutting knife 14 and ear cutting knife 15, the length of complete disconnected cutting knife 14 is greater than the length of housing cutting knife 13, and the length of ear cutting knife 15 is less than the length of housing cutting knife 13; The corresponding ear cutting knife of lower bolster 12 15 places are provided with ear lower cutter 16.
As shown in Figure 6, become product 109 after the fixedly contraposition stamp of cope match-plate pattern 11 and lower bolster 12, tear eliminating on release liners 110, upper release liners waste material 111 on ear, tear eliminating under the following scrap rubber base material of release liners 110 on lower release liners waste material 112 and ear.
Be provided with pilot pin 17 on cope match-plate pattern 11, the corresponding pilot pin of lower bolster 12 17 places are provided with locating hole 18.When mold closing, pilot pin 17 is fastened in locating hole 18, plays the fixedly contraposition effect of cope match-plate pattern 11 and lower bolster 12.
Upper release liners and gum base materials are thrust along the product housing by the housing cutting knife, disconnected cutting knife all thrusts upper release liners, gum base materials and lower release liners entirely, and the ear cutting knife thrusts release liners in the ear place, and the ear lower cutter thrusts ear place's base stock and glue.Several cutters are integrated on a secondary mould, utilize the toughness of material and time difference to realize punching press, effectively reduced production cost, improved production efficiency and Product Precision.
Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from spirit or scope of the present utility model, realization in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
