[0026] Refer to Figures 1-5 , a split bolt stamping die female die structure, including an upper female die 1 and two fixing mechanisms;

[0027] The bottom of the upper female die 1 is fixedly connected with a collar 2, the lower female die 3 is inserted into the collar 2, and two fixing mechanisms are both arranged on the lower female die 3, and both fixing mechanisms are connected with the collar 2;

[0028] The fixing mechanism includes a moving rod 4, a spring 5 and a slider 6. The lower female die 3 is provided with a first sliding groove, and two moving rods 4 are both slidably connected in the two first sliding grooves. The two moving rods 4 are both slidably connected with the collar 2. One end of the moving rod 4 is fixedly connected with a spring 5, and one end of the spring 5 is fixedly connected with the lower female die 3. Through the cooperative design of the upper female die 1, the collar 2, the lower female die 3, the fixing mechanism and the dovetail block 8, when the upper female die 1 or the lower female die 3 is damaged, only the damaged female die needs to be replaced, and there is no need to replace the entire bolt stamping female die, which has the advantages of saving materials and reducing processing costs, and is simple in structure and easy to operate, with higher practicability.

[0029] In this embodiment, two sliding grooves II are formed on the lower female mold 3, and two sliders 6 are slidably connected in the two sliding grooves II. The two sliders 6 are respectively fixedly connected to the two moving rods 4, which improves stability and enables the moving rods 4 to slide smoothly on the lower female mold 3.

[0030] In this embodiment, two grooves I 7 are formed on the collar 2, and the two moving rods 4 slide in the two grooves I 7 respectively. Thus, through the interaction between the two moving rods 4 and the two grooves I 7 respectively, the effect of preventing the collar 2 from rotating is achieved.

[0031] In this embodiment, two dovetail grooves 9 are formed on the inner side of the collar 2, and two dovetail blocks 8 are slidably connected in the two dovetail grooves 9. The two dovetail blocks 8 are both fixedly connected to the lower female mold 3. Through the interaction between the two dovetail blocks 8 and the two dovetail grooves 9 respectively, the effect of preventing the lower female mold 3 from detaching from the collar 2 is achieved.

[0032] In this embodiment, two grooves II 12 are formed on the collar 2, and the two grooves II 12 are respectively adapted to the two dovetail blocks 8, which facilitates the connection between the two dovetail blocks 8 and the two dovetail grooves 9.

[0033] In this embodiment, the two grooves II 12 correspond to the two dovetail grooves 9 respectively, which further facilitates the connection between the two dovetail blocks 8 and the two dovetail grooves 9.

[0034] In this embodiment, a first shaping cavity 10 is provided on the upper female mold 1. Bolts 14 are threadedly connected to the two moving rods 4. One ends of the two bolts 14 respectively penetrate through the two moving rods 4 and are both connected to the lower female mold 3, preventing the two moving rods 4 from moving during the processing.

[0035] In this embodiment, a second shaping cavity 13 is provided on the lower female mold 3. The second shaping cavity 13 is adapted to the first shaping cavity 10. A bolt 11 is provided in the second shaping cavity 13 for shaping the bolt 11.

[0036] Working principle: When in use, first, one end of the lower female mold 3 is aligned with the collar 2 on the upper female mold 1, and the two dovetail blocks 8 on the lower female mold 3 are respectively aligned with the two second grooves 12 on the collar 2. At the same time, the two first grooves 7 on the collar 2 are respectively aligned with the two moving rods 4. Then, one end of the lower female mold 3 is inserted into the collar, and the lower female mold 3 contacts the upper female mold 1, and the first shaping cavity 10 on the upper female mold 1 is aligned with the second shaping cavity 13 on the lower female mold 3. During this process, the collar 2 acts on the two moving rods 4, causing the two moving rods 4 to slide downward on the lower female mold 3 by a certain distance and respectively compressing the two springs 5. At the same time, the two dovetail blocks 8 on the lower female mold 3 are respectively aligned with the two dovetail grooves 9 on the collar 2. After that, the upper female mold 1 is rotated by a certain angle, and the upper female mold 1 drives the collar 2 to rotate synchronously by a certain angle. At the same time, the two moving rods 4 slide a certain distance in the two first grooves 7 respectively. At the same time, the two dovetail blocks 8 are respectively engaged with the two dovetail grooves 9, and the two dovetail blocks 8 slide a certain distance in the two dovetail grooves 9 respectively. During this process, when the moving rod 4 moves to the rightmost end of the first groove 7, the corresponding spring 5 acts on it to make the moving rod 4 return to its original state. Thus, by the blocking of the two moving rods 4 on the collar 2, then, rotate the two bolts 14 and connect the two bolts 14 to the lower female mold 3, so as to achieve the effect of preventing the collar 2 from rotating; at the same time, through the interaction between the two dovetail blocks 8 and the two dovetail grooves 9, the effect of preventing the lower female mold 3 from detaching from the collar 2 is achieved, and then the effect of connecting the upper female mold 1 and the lower female mold 3 is achieved;

[0037] When the upper female mold 1 or the lower female mold 3 is damaged, first, disconnect the two bolts 14 from the lower female mold 3, slide the two moving rods 4 downward, and release the blocking of the two moving rods 4 on the collar 2. Then, rotate the collar 2 in the reverse direction by a certain distance, and make the two dovetail blocks 8 disengage from the two dovetail grooves 9 respectively. After that, pull out the lower female mold 3 from the collar 2, so as to achieve the effect of disassembling the upper female mold 1 and the lower female mold 3. Finally, replace the damaged female mold.

[0038] The technical progress obtained by the present utility model compared with the prior art is that when the upper female mold 1 or the lower female mold 3 is damaged, only the damaged female mold needs to be replaced, without replacing the entire bolt stamping female mold, which has the advantages of saving materials and reducing processing costs. Moreover, the structure is simple and easy to operate, and the practicability is higher.
