Detailed Description

The knife mold for the membrane switch is further described with reference to fig. 1 to 2.

The utility model provides a cutting die for membrane switch, as shown in fig. 1, includes cutting die board 1 and installs the die-cutting rule 2 on cutting die board 1, and cutting die board 1 is whole to be square form, and the symmetry is provided with two die-cutting rules 2 on cutting die board 1, and two die-cutting rules 2 are symmetrical in the setting of the central line of cutting die board 1 to can once cut out two products, improve production efficiency.

As shown in fig. 1 and 2, the die-cutting rule 2 includes an outer frame cutter 21 and a plurality of inner cutters 22 disposed in the outer frame cutter 21, and the cross sections of the outer frame cutter 21 and the inner cutters 22 are both rectangular. The cutter grooves 11 are formed in the cutter template 1, the outer frame cutter 21 and the inner cutters 22 are respectively arranged in the cutter grooves 11 and are bonded through an adhesive, and the stability of the die-cutting cutters 2 arranged on the cutter template 1 is improved, so that the cutting effect is improved.

As shown in fig. 1 and 2, a plurality of interior cutters 22 are listed in outer frame cutter 21 with no less than one row, and the interior cutter 22 quantity of one of them row is less than other rows, and the mid portion of this row is blank setting simultaneously to when cutting out each membrane switch's orderly button mouth, can keep the covering surface and supply other parts of membrane switch to install, improve the installation convenience after the membrane switch closes. Specifically, in this embodiment, the plurality of inner cutters 22 are distributed in two rows in the width direction of the outer frame cutter 21, and nine inner cutters 22 are specifically arranged and are respectively divided into six rows and three rows. Wherein three interior cutters 22 are the both ends that should be arranged in this row of interior cutter 22 of being listed as respectively, and the top is established to an interior cutter 22, and the bottom is provided with two to cut out required membrane switch shape, overall structure is simple, orderly and reasonable.

As shown in fig. 1, the two ends of the inner cutter 22 are provided with the positioning knives 3, the positioning knives 3 are arranged in the die-cutting knife 2 corresponding to the rows of the inner cutter 22, and the four positioning knives 3 are arranged close to the four corners of the inner wall of the outer frame cutter 21, so that the mounting holes of the membrane switch can be cut by the positioning knives 3 when the membrane switch is cut, and the membrane switch can be mounted conveniently.

As shown in fig. 1 and 2, the positioning blade 3 is further in a closed frame shape that is connected end to end, specifically, the cross section of the positioning blade 3 is configured in a circular ring shape to cut a circular hole on the membrane switch. Wherein an elastic material ejecting block 4 is arranged in the frame of the positioning knife 3, the elastic material ejecting block 4 is arranged into a cylinder shape corresponding to the positioning knife 3, and the elastic material ejecting block 4 is arranged into a spring column so as to extrude the cut waste material by utilizing the elastic deformation capability. Meanwhile, the positioning knife 3 and the elastic ejector block 4 are symmetrically arranged corresponding to the die-cutting knife 2, so that two products can be cut simultaneously, and the production efficiency is improved.

As shown in fig. 1 and 2, one end of the elastic ejector block 4 is fixed on the cutter template 1, the other end of the elastic ejector block extends out of the frame of the positioning cutter 3 and forms a contact end 41, and the height of the contact end 41 is higher than that of the cutter point of the die cutter 2, so that when cutting is performed, the contact end 41 firstly abuts against the product to fix the product, then the die cutter 2 is used for cutting, and meanwhile, along with the continuous deepening of the cutting depth, the elastic ejector block 4 is pressed to generate elastic force opposite to the cutting force, so that the cutting depth is limited, the product is prevented from being cut, and the cutting precision is improved; on the other hand, when the die is removed, the waste can be discharged from the frame of the positioning knife 3 by using the elastic force, so that the use convenience is improved. Specifically, the abutting end 41 is set to be conical, so that the product is preferentially stressed on the product, and the product is conveniently positioned in advance.

Through the scheme, the inner cutters 22 of the cutters are reasonably arranged, the positioning cutters 3 and the elastic ejection blocks 4 are matched to fix the material belt and then die cut, the mounting holes are directly cut, and the effect of improving the convenience of die cutting is achieved.
