[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0019] like Figure 1 , 2 As shown, in the first embodiment of the punching mold for the right longitudinal tube of the car seat backrest of this utility model, the punching mold 10 includes an upper mold 11, a lower mold 12, a guide post 13 disposed on the upper mold 11, and a guide hole 14 disposed on the lower mold 12 for the guide post 13 to be inserted and connected.

[0020] The lower mold 12 is provided with a cavity 15 into which the longitudinal tube 28 can be inserted. The lower mold 12 is provided with at least one first slider 16 on the first side of the cavity 15, which can slide along the vertical direction of the cavity 15. The lower mold 12 is provided with at least one second slider 17 on the second side of the cavity 15, which can slide along the vertical direction of the cavity 15. The first slider 16 is provided with at least one first punch 18 that can be inserted into the cavity 15 and punch the first side of the longitudinal tube 28. The second slider 17 is provided with at least one second punch 19 that can be inserted into the cavity 15 and punch the second side of the longitudinal tube 28.

[0021] The bottom of the upper mold 11 is provided with a first oblique insert 20 that pushes the first slider 16 to move closer to the cavity 15 when the upper mold 11 moves downward. The bottom of the upper mold 11 is also provided with a second oblique insert 21 that pushes the second slider 17 to move closer to the cavity 15 when the upper mold 11 moves downward.

[0022] When using the punching die for the right longitudinal tube of the car seat backrest of this utility model, the longitudinal tube 28 can be inserted into the cavity 15. The upper die 11 moves downward, causing the first inclined insert 20 and the second inclined insert 21 to move downward. During the downward movement of the first inclined insert 20, it pushes the first slider 16 to move closer to the cavity 15. The first slider 16 drives the first punch 18 to insert into the cavity 15 and punch a hole on the first side of the longitudinal tube 28. Similarly, during the downward movement of the second inclined insert 21, it pushes the second slider 17 to move closer to the cavity 15. The second slider 17 drives the second punch 19 to insert into the cavity 15 and punch a hole on the second side of the longitudinal tube 28. The punching die 10 of this application only requires one die 10 to realize the two punching processes of the longitudinal tube 28, reducing the number of personnel and saving two punch presses, reducing the number of die changes and the number of scrapped products due to die change and debugging, saving processing costs, and greatly improving production efficiency.

[0023] In the embodiment, the first slider 16 is provided with a first inclined surface 22 corresponding to the first inclined insert 20 on the side surface away from the first punch 18, and the second slider 17 is provided with a second inclined surface 23 corresponding to the second inclined insert 21 on the side surface away from the second punch 19.

[0024] During the downward movement of the upper die 11, the first inclined insert 20 abuts against the first inclined surface 22 and pushes the first slider 16 in the direction of the cavity 15, forming a first direction punching hole. The second inclined insert 21 abuts against the second inclined surface 23 and pushes the second slider 17 in the direction of the cavity 15, forming a second direction punching hole.

[0025] Specifically, the lower die 12 is provided with a first sliding groove or a first sliding rail for guiding the movement of the first slider 16, and the direction of the first sliding groove or the first sliding rail is perpendicular to the length direction of the cavity 15. The lower die 12 is also provided with a second sliding groove or a second sliding rail for guiding the movement of the second slider 17, and the direction of the second sliding groove or the second sliding rail is perpendicular to the length direction of the cavity 15.

[0026] Further, in order to facilitate the resetting of the first slider 16 and the second slider 17 after the punching is completed, the lower die 12 is provided with a first spring for pushing the first slider 16 to move in the direction away from the cavity 15 for resetting. The lower die 12 is also provided with a second spring for pushing the second slider 17 to move in the direction away from the cavity 15 for resetting.

[0027] In order to achieve better positioning effect, the lower die 12 is provided with a first positioning block 24 at the end of the cavity 15 for blocking the first end of the longitudinal pipe 28.

[0028] Further, the first cavity 15 is fixedly provided with a core rod 25 for supporting the longitudinal pipe 28, and the end of the core rod 25 is fixedly connected with the first positioning block 24. The core rod 25 is provided with a first clearance hole and a second clearance hole at positions corresponding to the first punch 18 and the second punch 19, respectively.

[0029] Further, the outer side wall of the lower die 12 is fixedly provided with a positioning rod 26 parallel to the longitudinal pipe 28, and the end of the positioning rod 26 is provided with a second positioning block 27 for blocking the second end of the longitudinal pipe 28 when the longitudinal pipe 28 is inserted into the cavity 15. The second positioning block 27 is detachably connected, slidingly connected or rotatably connected with the positioning rod 26.

[0030] After the longitudinal pipe 28 is inserted into the cavity 15, the longitudinal pipe 28 is sleeved on the core rod 25 and supported by the core rod 25. The first end of the longitudinal pipe 28 abuts against the first positioning block 24, and then the second positioning block 27 is manually adjusted so as to abut against the second end of the longitudinal pipe 28, thereby achieving the positioning of the longitudinal pipe 28 and preventing displacement of the longitudinal pipe 28 during the processing, improving the processing precision.

[0031] Preferably, the positioning rod 26 is provided with an insertion hole for inserting the second positioning block 27, when the second positioning block 27 is inserted into the insertion hole, the second positioning block 27 is perpendicular to the longitudinal pipe 28 and abuts against the second end of the longitudinal pipe 28, thereby blocking the second end of the longitudinal pipe 28.

[0032] In addition, in the present application, unless otherwise clearly specified and limited, the terms "connected", "connected", "stacked" and the like should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For ordinary skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0033] The above is only an embodiment of the present application, and does not limit the patent range of the present application, and any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields by using the content of the present application specification and drawings, are also included in the patent protection range of the present application.
