In addition, the die 4 is installed more stably, so that the die-cutting quality is higher, and the use economy of the device is higher.

[0027] Embodiment 2

[0028] On the basis of embodiment 1, in order to realize the convenient movement of the card block 10, installation grooves 6 are opened on the left and right sides of the interior of the body 1, and a rotating shaft 7 is rotatably connected to the interior of the front end of the body 1. The body 1 limits the rotating shaft 7, so that the rotating shaft 7 can rotate smoothly. A pull rope 8 is fixedly connected to the outside of the rotating shaft 7, and the pull rope 8 is slidably connected to the inside of the installation groove 6. The installation groove 6 limits the pull rope 8, so that the pull rope 8 will not deviate during movement. An elastic block 9 is sleeved on the outside of the pull rope 8, and the separated sides of the two elastic blocks 9 are respectively fixedly connected to the adjacent sides of the two card blocks 10, and the card block 10 is slidably connected to the inside of the installation groove 6.

[0029] When the elastic block 9 needs to be moved, the rotating shaft 7 is rotated so that the rotating shaft 7 can wrap the pull rope 8 around its outside, and then the pull rope 8 can pull the card block 10 to move inward, so that the card block 10 can squeeze the elastic block 9 to produce deformation, and then the card block 10 can be separated from the inside of the card slot 5. When the rotating shaft 7 is released, the elastic block 9 can perform a reset movement, and then the elastic block 9 can push the card block 10 to engage with the inside of the card slot 5.

[0030] Embodiment 3

[0031] On the basis of the second embodiment, in order to realize the convenient replacement of the mold core 11, a plurality of elastic rings 17 are provided inside the concave mold 4, a plurality of sleeves 12 are fixedly connected to the bottom end of the mold core 11, a slide groove 13 is provided inside the sleeve 12, an elastic block 2 14 is fixedly connected to the upper side of the inner wall of the slide groove 13, a push piece 15 is fixedly connected to the bottom end of the elastic block 2 14, the outer part of the push piece 15 is slidably connected to the inside of the slide groove 13, the slide groove 13 limits the internal push piece 15, so that the push piece 15 can slide smoothly, and the bottom end of the push piece 15 is fixedly connected to the connecting block 1 6. The outside of the connecting block 16 is slidably connected to the inside of the die 4, and the die 4 limits the connecting block 16, so that the connecting block 16 will not be offset when moving. The upper side of the outer side of the slide 13 is fixedly connected with a placement groove 18, and the middle part of the elastic block 14 is on the same horizontal line as the placement groove 18, so that when the elastic block 14 is squeezed and deformed, the elastic block 14 can push the placement groove 18 to move, and the elastic ring 17 matches the placement groove 18, and the placement groove 18 is engaged with the elastic ring 17, so that the slide 13 can be stably installed inside the die 4.

[0032] When the mold core 11 needs to be installed, the mold core 11 is slid into the interior of the die 4, so that the slide groove 13 and the connecting block 16 can slide into the internal groove of the die 4. When the connecting block 16 fits with the inner wall of the groove of the die 4, the position of the connecting block 16 remains unchanged. Under the reaction force, the push piece 15 can be pushed upward in the opposite direction, so that the push piece 15 can squeeze the elastic block 2 14 to produce deformation, so that the elastic block 2 14 can push the slide groove 13 and the placement groove 18 to open outward, so that the placement groove 18 can be engaged with the inside of the elastic ring 17, so that the mold core 11 can be conveniently installed, otherwise, it can be conveniently disassembled. By replacing the mold core 11, there is no need to replace the die 4 under the same size, thereby reducing the replacement steps and further improving the die-cutting efficiency of the rubber diaphragm.

When the connecting block 16 fits with the inner wall of the groove of the die 4, the position of the connecting block 16 remains unchanged. Under the reaction force, the push piece 15 can be pushed upward in the opposite direction, so that the push piece 15 can squeeze the elastic block 14 to produce deformation, so that the elastic block 14 can push the slide groove 13 and the placement groove 18 to open outward, so that the placement groove 18 can be engaged with the inside of the elastic ring 17, so that the mold core 11 can be conveniently installed. Secondly, by rotating the shaft 7, the shaft 7 can wrap the pull rope 8 around its outside. Then the pull rope 8 can pull the card block 10 to move inward, so that the card block 10 can squeeze the elastic block 9 to produce deformation. At this time, the card block 10 can enter the interior of the installation groove 6, and then the die 4 is fitted with the upper side of the body 1, and the die 4 is slid backward, so that the limit block 3 can slide into the interior of the limit groove 2. Finally, by loosening the rotating shaft 7, the elastic block 9 can perform a reset movement, and then the elastic block 9 can push the card block 10 to engage with the interior of the card slot 5, so that the die 4 and the mold core 11 can be conveniently installed, so that the device has high flexibility in use and will not affect the die-cutting progress of the rubber diaphragm, so that the device has high economic efficiency.
