[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 3 The utility model provides a metal mold processing fixture, including a support leg 1, the top of the outer wall of the support leg 1 is fixedly connected to a workbench 2, the inner wall of the workbench 2 is rotatably connected to a telescopic rod 8, the telescopic rod 8 is a prior art, and is composed of two groups of rod bodies spliced ​​together. When the telescopic rod 8 is lowered by stepping on a pedal 6, it will be adjusted according to the extension height of the pedal 6.

[0025] See also Figure 1 and Figure 2 One end of the telescopic rod 8 is fixedly connected to a pedal 6, and the other end of the telescopic rod 8 is hinged with a moving seat 3. By pressing the pedal 6 down, the telescopic rod 8 drives the moving seat 3 to rise on the inner wall of the workbench 2 to adjust according to the thickness of the metal mold. The inner side wall of the moving seat 3 is slidably connected to a moving plate 5. Two groups of support rods 4 are fixedly connected to the surface of the workbench 2. The shape of the two groups of support rods 4 is cylindrical, corresponding to the arc opened at the top of the clamping plate 13. The rotation center axis of the telescopic rod 8 has a limiting wheel 7, which is rotatably connected to the inner wall of the workbench 2, and the moving seat 3 is slidably connected to the inner wall of the workbench 2.

[0026] See also Figure 3 The inner wall of the workbench 2 is elastically connected to the limit block 10 through the limit spring 9, and the limit block 10 is slidably connected to the inner wall of the workbench 2. The surface of the workbench 2 is provided with a guide groove that fits the operating block on the surface of the limit block 10, so that the limit block 10 can only move on the inner wall of the workbench 2 and cannot be separated from its inner wall. The surface of the limit wheel 7 is provided with multiple sets of racks, and the limit block 10 is engaged with the rack. The engagement between the two allows the rotation position of the limit wheel 7 to only rotate clockwise and cannot be counterclockwise. Rotate, one end of the limit spring 9 is fixedly connected to the top of the inner wall of the workbench 2, and the other end of the limit spring 9 is fixedly connected to the top of the outer wall of the limit block 10. When the limit wheel 7 rotates, the arc surface of the rack on its surface will squeeze the arc surface of the limit block 10, allowing it to move upward on the inner wall of the workbench 2 until it reaches the next set of racks of the limit wheel 7. It will be affected by the elastic action of the limit spring 9 and restored to its initial position to engage with the rack at the current position of the limit wheel 7 to fix the moving position of the limit wheel 7.

[0027] See also Figure 4 The inner wall of the movable plate 5 is provided with two sets of clamping mechanisms, the clamping mechanisms include a clamping plate 13, the top of the clamping plate 13 is provided with an arc surface, the arc surface portion corresponds to the support rod 4, the top of the outer wall of the clamping plate 13 is in contact with the bottom end of the outer wall of the support rod 4, and the support rod 4 is pressed by the rise of the clamping plate 13, so that the metal mold is clamped and fixed, and the bottom end of the outer wall of the clamping plate 13 is fixedly connected with a sliding column 12, and the sliding column 12 is elastically connected to the outer wall of the clamping plate 13 by a return spring 11. The inner wall of the movable plate 5, one end of the return spring 11 is fixedly connected to the bottom end of the inner wall of the movable plate 5, and the other end of the return spring 11 is fixedly connected to the bottom end of the outer wall of the sliding column 12. When the clamping plate 13 rises, it will be squeezed by the support rod 4, so as to clamp and fix the mold. When the contact movable seat 3 rises, the sliding column 12 will be affected by the elastic action of the return spring 11, and it and the clamping plate 13 will be synchronously restored to the initial position. The sliding column 12 is slidably connected to the inner wall of the movable plate 5.

[0028] Working principle: When processing the metal mold, first place the metal mold in the groove corresponding to the surface of the movable plate 5. At this time, the pedal 6 is pressed to drive the telescopic rod 8 to move downward. When the pedal 6 moves downward, the other end of the telescopic rod 8 will drive the movable seat 3 to move upward on the inner wall of the workbench 2. At the same time, when the telescopic rod 8 rotates, the limiting wheel 7 of its rotating center axis will rotate synchronously. When the limiting wheel 7 rotates, the arc surface of the rack on its surface will squeeze the arc surface of the limiting block 10, allowing it to move upward on the inner wall of the workbench 2 until it reaches the next set of racks of the limiting wheel 7, where it will be subject to the elastic action of the limiting spring 9, restoring it to its initial position to engage with the rack at the current position of the limiting wheel 7 to fix the moving position of the limiting wheel 7, and so on.

[0029] When the clamping plate 13 contacts the bottom end of the support rod 4, the clamping plate 13 will be squeezed to drive the sliding column 12 to move downward on the inner wall of the movable plate 5, so as to clamp and fix the molds of different thicknesses. When adjusted to a suitable position, the limiting wheel 7 will be clamped by the limiting block 10 at the current position. At this time, the metal mold can be directly processed. When the processing position of the metal mold needs to be adjusted, the movable plate 5 can be directly moved on the inner wall of the movable seat 3. Because of the setting of the arc surface at the top, the friction between it and the support rod 4 is reduced, so that the movable plate 5 will not be affected by the friction when it moves.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
