Specific embodiment
Specific embodiment of the present utility model and working principle are described in further detail with reference to the accompanying drawing.
As shown in FIG. 1 to 3, a kind of band film conducting foam punching mould, including die ontology 1, in the die ontology 1
Lower surface offers rectangular recess 2, and the mold cutter being adapted with die cutting product frame structure is provided in the rectangular recess 2
3, it is also set up in the rectangular recess 2 there are two punching cutter 4, and the punching cutter 4 is close to the middle part of the mold cutter 3
Setting, the height of the punching cutter 4 are higher by 0.15mm than the height of mold cutter 3, are arranged at the center of the punching cutter 4
There is waste material self-unloading hole 5,5 outer dimension of waste material self-unloading hole and the punching cutter 4 are adapted, and extend upwardly to the mold
The upper surface of ontology 1.It is additionally provided with and is covered in the mold cutter 3 and the bullet on punching cutter 4 in the rectangular recess 2
Property top stock layer 6, the slot being adapted with the mold cutter 3 with punching cutter 4 or hole are provided on the elasticity top stock layer 6；
The mold cutter 3 by the first bending part 31, first straight line 32, the second bending part 33, second straight line 34 with
And third bending part 35 is connected in sequence, wherein the outline border of the first bending part 31 and third bending part 35 and die cutting product both ends
