[0020] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0021] Please refer to Figures 1 to 4 A stamping closed slider structure comprises a slide 1 and a stamping block 2, wherein the slide 1 is provided with an installation opening 11 in the middle part, and a plurality of installation grooves 12 are circumferentially provided on the inner wall of the installation opening 11, and a plurality of the stamping blocks 2 are movably arranged in the installation groove 12 up and down, and the installation groove 12 is provided with a guide groove 13 inclined toward the middle part of the installation opening 11 in the height direction of the installation opening 11, and the stamping block 2 is provided with a guide block 21 corresponding to the guide groove 13 and movably matched therewith; a plurality of the stamping blocks 2 are enclosed to form a stamping structure having a stamping opening in the middle part which is consistent with the shape of the stamped product; the stamping block 2 comprises a connecting block 22 and a punching block 23, and the connecting block 22 and the punching block 23 are detachably connected in sequence along the height direction of the stamping opening.

[0022] From the above description, it can be seen that the beneficial effect of the utility model is that: during stamping, the upper and lower die seats are used to push the slide 1 and the punching block 2, so that the punching block 2 can move along the guide groove 13 in the installation groove 12 toward the middle of the installation port 11, until the stamping structure enclosed by multiple stamping blocks 2 matches the size of the product to be stamped, and the punching part of the stamping structure performs closed punching on the product; then the upper and lower die seats move away from each other, and the stamping block 2 moves away from the middle of the installation port 11 along the guide groove 13. At this time, the product will not be attached to the stamping block 2, and the punched product can be easily removed and transferred to the next process; at the same time, the stamping block 2 adopts the design of the connecting block 22 and the punching block 23, which can adjust the punching accuracy in time, and the punching block 23 that has been used as the punching part for a long time can be conveniently disassembled and maintained.

[0023] Furthermore, a slide groove 221 is provided at the lower end of the connecting block 22, whose length direction is perpendicular to the height direction of the punching port, and the inner walls on both sides of the slide groove 221 are concave; a sliding block 231 is provided at the upper end of the punching block 23 corresponding to the slide groove 221, and limit blocks 232 are protruded on both sides of the sliding block 231 to match the concave inner walls of the slide groove 221.

[0024] From the above description, it can be seen that the connection block 22 and the punching block 23 are quickly combined by the cooperation of the slide groove 221 at the lower end of the connection block 22 and the sliding block 231 of the punching block 23; wherein the punching block 23 is fixed in the height direction of the punching port by the cooperation of the concave inner walls on both sides of the slide groove 221 and the protruding limit blocks 232 on both sides of the sliding block 231.

[0025] Furthermore, a stopper 222 is provided at one end of the slide groove 221 in the length direction, and a slot 223 is provided in the middle of the stopper 222 ; an inserting block 233 adapted to the slot 223 is provided on the side of the punching block 23 opposite to the stopper 222 .

[0026] From the above description, it can be seen that the stop block 222 in the length direction of the slide groove 221 is used to limit the sliding distance of the punching block 23 when it slides in, so as to ensure that the punching block 23 after matching with the connecting block 22 can form a stamping structure that matches the shape of the product; and the setting of the slot 223 and the insert block 233 further improves the tightness of the matching between the two.

[0027] Furthermore, it also includes a limit pin 3, a first limit hole 224 is provided at the lower end of the connecting block 22, and a concave structure is provided on one side of the first limit hole 224; a second limit hole 234 is provided on the punching block 23, and the cross-section of the second limit hole 234 in the length direction is consistent with the cross-section of the first limit hole 224 in the length direction; a protruding structure is provided on one side of the limit pin 3, and the limit pin 3 passes through the first limit hole 224 and the second limit hole 234 at the same time, and the protruding structure on one side of the limit pin 3 matches the concave structure on one side of the first limit block 232 and the second limit hole 234.

[0028] It can be seen from the above description that, through the plug-in cooperation between the limit pin 3 and the first limit hole 224 at the lower end of the connecting block 22 and the second limit hole 234 passing through the punching block 23, the punching block 23 can be fixed in the direction perpendicular to the punching port after sliding into the slide groove 221; combined with the cooperation between the limit block 232 and the concave inner wall of the slide groove 221, the punching block 23 is completely fixed on the connecting block 22; after the limit pin 3 is inserted into the second limit hole 234 and the first limit hole 224, the protruding structure of the limit pin 3 is engaged with the concave structure of the first limit hole 224 and the second limit hole 234 by rotation, thereby fixing the punching block 23 and the connecting block 22.

[0029] Furthermore, it also includes a fixing bolt 4, and a thread is provided on the inner wall of the second limiting hole 234 of the punching block 23 close to the lower end surface of the punching block 23; the fixing bolt 4 is locked and connected with the second limiting hole 234; one end of the fixing bolt 4 is against the limiting pin 3.

[0030] From the above description, it can be seen that the locking setting of the fixing bolt 4 at the second limiting hole 234 and its abutment against the limiting pin 3 can prevent the limiting pin 3 from rotating under the action of external force and thus make the connection between the connecting block 22 and the punching block 23 invalid.
