[0028] Example 1

[0029] like Figures 1 to 6 As shown, a tooling fixture for processing a folding machine mold includes a base 10, on which a limiting plate 11, a positioning plate 12 and a clamping assembly are installed. The positioning plate 12 is fitted with the head of the folding machine mold 20, and the clamping assembly is clamped and fixed on the limiting plate 11 from the side of the folding machine mold 20.

[0030] The clamping assembly includes a clamping block 13, a slider 14 and a pressure piece 15. One end of the pressure piece 15 passes through the clamping block 13 and is installed on the base 10, and the other end is an operating end. Pressure surfaces are provided on both sides of the clamping block 13. Two sliders 14 are provided and are located on both sides of the clamping block 13. A spring piece 16 is installed between the two sliders 14. The pressure surface is used to force the slider 14 to move to both sides.

[0031] The head of the folding machine mold 20 is attached to the positioning plate 12 and is located on the base 10 between the limit plate 11 and the clamping assembly. By adjusting the pressure piece 15, the pressure piece 15 will act on the slider 14 to move to both sides through the pressure surface, and the spring piece 16 is stretched. The slider 14 presses the folding machine mold 20 on the limit plate 11 through the side. The positioning plate 12 can ensure the flatness and parallelism of the bottom surface of the folding machine mold 10.

[0032] Embodiment 2, in the fixture, as Figure 5 As shown, the base 10 is provided with a guide 17, and a side of the slider 14 opposite to the base 10 is provided with a transverse groove 18, and the transverse groove 18 and the guide 17 are slidably matched. The guide 17 and the transverse groove 18 are adapted to ensure that the slider 14 always moves transversely during the movement process to prevent deviation. The guide 17 is two parallel pins, which are inserted into the base 10.

[0033] Embodiment 3, in the fixture, as Figure 5 As shown, the pressure surface is a wedge-shaped surface, which gradually approaches the middle part along the direction close to the base 10, and the slider 14 is provided with a pressure-bearing surface, which gradually deviates from the pressure-applying member 15 along the direction away from the base 10. Through the interaction between the pressure-applying surface and the pressure-bearing surface, it can be ensured that the pressing block 13 and the slider 14 can be automatically reset through the spring member 16 after the pressure-applying member 15 releases the force.

[0034] Embodiment 4, in the fixture, as Figure 5 As shown, the pressure member 15 includes a connecting bolt, an internal threaded hole is installed on the base 10, and a through hole is provided on the pressing block 13. One end of the connecting bolt passes through the through hole on the pressing block 13 and is connected to the internal threaded hole. The connecting bolt and the internal threaded hole are adapted to adjust the distance between the pressing block 13 and the base 10.

[0035] Embodiment 5, in the fixture, as Figure 5 As shown, the pressure member 15 also includes a spring body 19. A countersunk hole is installed on the base 10. The spring body 19 is installed in the countersunk hole and one end abuts against the bottom of the pressing block 13. The spring body 19 can avoid the pressing block 13 and the slider 14 from being crushed.

[0036] Embodiment 6, in the fixture, as Figure 5 and Figure 6 As shown, both ends of the slider 14 are provided with connecting pins 141, and two connecting pins 141 located on the same side and corresponding to each other on the two sliders 14 are respectively hooked on both ends of the spring member 16. The connecting pins 141 can ensure the connection between the spring member 16 and the slider 14.

[0037] Embodiment 7, in the fixture, as Figure 6 As shown, a rubber sheet is provided in the middle of one side of the slider 14 relative to the folding machine mold 20 to reduce the rigid contact surface, increase the friction resistance, and prevent deviation during processing.

[0038] Embodiment 8, in the fixture, as Figure 7 and Figure 8 As shown, an L-shaped limit plate 142 is provided on the side of the slider 14 away from the base, and the free end of the L-shaped limit plate 142 is attached to the folding machine mold 20 to limit the folding machine mold and ensure processing accuracy.

[0039] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution and inventive concept of the utility model should be included in the protection scope of the utility model.
