Description

Technical Field

[0001] The utility model relates to the technical field of die-cutting dies, in particular to a die-cutting die for EMI buffering and shielding products. Background Art

[0002] EMI buffering and shielding products are a type of material or component specifically designed to reduce or eliminate electromagnetic interference. They are widely used in various electronic devices to ensure the normal operation of the equipment and the accuracy of data transmission.

[0003] After the conductive foam products are produced, they need to be processed into holes of various shapes and sizes. When using die-cutting dies to die-cut the conductive foam, since the conductive foam is usually composed of a variety of materials, such as composite aluminum foil, double-sided conductive tape and PU sponge, the viscosity and elasticity of these materials will cause adhesion to the tool during the die-cutting process, requiring subsequent manual cleaning of the waste after die-cutting, resulting in low production efficiency. Therefore, we need to propose a die-cutting die for EMI buffer shielding products. Utility Model Content

[0004] The purpose of the present utility model is to provide a die-cutting die for EMI buffer shielding products. When waste materials are stuck in the die-cutting tool, there is no need for manual operation to clean the waste materials, thereby improving the convenience of cleaning the waste materials in the die-cutting tool and solving the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] The EMI buffer shielding product die-cutting die includes an upper die and a lower die. An adjustment plate is provided inside the upper die. The bottom of the adjustment plate is fixedly connected to multiple sets of die-cutting tools. Each set of die-cutting tools is provided with a pushing mechanism.

[0036] In an optional embodiment, a connecting seat 2 is movably inserted into the upper mold 1 , and the bottom of the pressing plate 3 contacts the top of the adjusting plate 4 .

[0037] It should be noted that the connecting seat 2 is installed on a lifting device, and the positions of the upper mold 1 and the adjustment plate 4 can be adjusted by the lifting device, so that the conductive foam product can be processed.

[0038] In an optional embodiment, a plurality of through holes 17 corresponding to the die cutting tools 8 are provided on the pressing plate 3 , and the die cutting tools 8 are disposed in the through holes 17 .

[0041] In an optional embodiment, a plurality of first avoidance grooves 19 corresponding to the die cutting tools 8 are provided on the top of the lower mold 18 .

[0042] It should be noted that, through the setting of the first avoidance groove 19, after the die-cutting tool 8 punches a hole in the conductive foam product, the die-cutting tool 8 can move into the first avoidance groove 19, which plays a role in avoiding the die-cutting tool 8 and preventing the die-cutting tool 8 from contacting the lower mold 18 and being damaged.

Then, the die-cutting tool 8 at the bottom of the adjusting plate 4 will press on the conductive foam product to punch out holes in the conductive foam product. When the die-cutting tool 8 punches out holes in the conductive foam product, the push pin 107 will first contact the conductive foam product, and after contacting the conductive foam product, the push pin 107 will roll along the surface of the conductive foam product, thereby opening the first push rod 102 and the second push rod 103. At this time, the die-cutting of the conductive foam product will not be affected, and when the die-cutting tool 8 punches out holes in the conductive foam product, the cutting knife 20 can cut the processed conductive foam product.

[0046] After the die-cutting tool 8 opens a hole in the conductive foam product, the waste will stick to the die-cutting tool 8. When the upper mold 1 is driven away from the lower mold 18 by the lifting equipment, the first push rod 102 and the second push rod 103 are dragged under the action of the push spring 104, so that the first push rod 102 and the second push rod 103 are close to each other, and the waste in the die-cutting tool 8 is pushed by the push column 107, so that the waste can be automatically discharged from the die-cutting tool 8. When the waste sticks to the die-cutting tool 8, there is no need for manual operation to clean the waste, which improves the convenience of cleaning the waste in the die-cutting tool 8.
