Detailed Description
The structure and operation of the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1-6, the present embodiment is a die-cutting die for a cambered surface foot pad, which includes a lower die 1, an upper die 2 and a die core 3; a convex part 11 used for jacking the middle part of the cambered foot pad 100 upwards is arranged on the lower die 1; the upper die 2 is arranged above the lower die 1, the upper die 2 is provided with a die core mounting cavity 21, the position of the die core mounting cavity 21 corresponds to the position of the bulge part 11, and the horizontal dimension of the die core mounting cavity 21 is larger than that of the bulge part 11; the mold core 3 is arranged in the mold core mounting cavity 21, the mold core 3 comprises a cutter pipe 31 and a cutter pipe supporting block 32, the cutter pipe 31 is sleeved outside the cutter pipe supporting block 32, a circle of tubular cutting edge 311 for punching the outer edge of the cambered foot pad 100 is arranged at the lower end of the cutter pipe 31, and the height of the tubular cutting edge 311 is lower than the height of the lower side surface of the upper mold 2 and the height of the lower side surface of the cutter pipe supporting block 32.
As shown in fig. 1-4, before the die-cutting die of the present invention is used, a foot pad material layer 200 is placed between the lower die 1 and the upper die 2 by a worker, and the foot pad material layer 200 is preferably a teflon foot pad material layer 200; after the foot pad material layer 200 is placed, a punching procedure is performed, and the punched cambered foot pad 100 refers to the cambered foot pad 100 shown in fig. 5-6. Referring to fig. 1-4 in combination, the specific punching procedure of the punching die of the present invention is as follows: in the process that the upper die and the die core are punched downwards to the lower die from top to bottom, the convex part on the lower die firstly jacks up the middle part of the foot pad material layer 200 corresponding to the position of the cambered surface foot pad 100; then, the tubular blade 311 of the knife tube 31 presses against the outer edge of the foot pad material layer 200 corresponding to the position of the cambered foot pad 100, and the edge part 101 of the cambered foot pad is quickly bent downwards, so that the periphery of the cambered foot pad 100 is rounded and curled; finally, the tubular blade 311 of the knife tube 31 continues to be punched downwards to completely cut off the outer edge of the foot pad material layer 200 corresponding to the cambered foot pad 100, and the edge part 101 of the cut-off cambered foot pad 100 has a cambered surface, referring to fig. 5-6. The utility model can generate fillet curling around the foot pad 100 in the process of punching the foot pad by the punching die, and form a cambered surface foot pad 100 with a cambered surface at the edge part 101; after the cambered surface foot pad 100 is adhered to the bottom of the mouse, in the using process of the mouse, the edge part 101 of the cambered surface foot pad 100 is not in direct contact with and rubs against the bearing surface, after long-term use, burrs are not formed on the edge part 101 of the cambered surface foot pad 100, and the stability and reliability of the mouse in moving are guaranteed.
As shown in fig. 2-6, the horizontal dimension of the tubular blade 311 of the knife tube 31 is larger than the horizontal dimension of the protrusion 11, when the knife tube 31 is punched on the lower die 1, the tubular blade 311 is sleeved outside the protrusion 11, and the distance between the tubular blade 311 and the outer edge of the protrusion 11 is 1-5mm, so that the punched cambered foot pad 100 has a cambered edge portion 101 with a depth of 1-5 mm. The upper surface of the lower die 1 and the upper surface of the boss 11 of the lower die are planes, the lower side surface of the upper die 2 is a plane, and the lower surface of the knife tube supporting block 32 of the die core 3 is a plane.
