[0004] Although the existing molds have a replaceable function, there are still some shortcomings. When installing and disassembling the mold, tools are needed and the bolts are rotated multiple times before the mold can be replaced, which increases the difficulty of replacing the mold. At the same time, when installing and disassembling the mold, the mold is directly below the stamping device, which increases the risk of replacing the mold. When fixing the mold, the position of the mold is installed according to the employee's feeling. Therefore, when stamping the hardware, it is easy for the stamped shape to fail to meet the required shape, thereby resulting in waste of hardware materials. For this reason, a positioning mold for hardware CNC machine tool processing is proposed to solve the above problems. Utility Model Content

[0031] 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.

[0032] Reference Figure 1-Figure 3 The utility model provides an embodiment: a positioning mold for hardware CNC machine tool processing, including a base 1, a shell 2 is fixedly connected to the top of the base 1, a stamping assembly 3 is arranged on the top of the shell 2, a flap 4 is rotatably connected to the top of the base 1, and a handle is fixedly connected to the outer side of the flap 4. The flap 4 can be closed when the device is not in use, thereby preventing dust from entering the flap 4 and accumulating, avoiding dust accumulation that causes the device to be unable to be used effectively, and at the same time reducing the number of times employees clean the device, thereby reducing the labor intensity of employees, and at the same time, the handle can facilitate employees to open or close the flap 4.

[0033] Reference Figure 3-Figure 5 The middle part of the base 1 is slidably connected with a shell 5, and a limiting groove is provided on the top of the base 1. The shell 5 is slidably connected to the middle part of the limiting groove. The limiting can provide space for the shell 5 to slide, so that the center position of the shell 5 can be in a vertical relationship with the center position of the stamping assembly 3 after the shell 5 moves, thereby improving the positioning effect of the mold, and the middle part of the shell 5 is rotatably connected with a gear ring 6, and the outer side of the gear ring 6 is fixedly connected with a plurality of meshing teeth 16. The middle part of the shell 5 is fixedly connected with a compression spring 14, and the other end of the compression spring 14 is fixedly connected with a rack plate 15. The inside of the base 1 is slidably connected with a partition, and the partition is fixedly connected between the compression spring 14 and the rack plate 15. The partition can prevent the rack plate 15 from tilting during the movement, thereby avoiding the compression spring 14 from being deformed and damaged due to tilting and extrusion, thereby improving the service life of the compression spring 14.

[0034] Reference Figure 3-Figure 5The rack plate 15 and the meshing teeth 16 are meshed with each other, and a movable groove 21 is provided in the middle of the base 1. The meshing teeth 16 are located in the middle of the movable groove 21. The movable groove 21 can provide a movable space for the meshing teeth 16, and at the same time, the shell 5 can keep the meshing teeth 16 and the rack plate 15 meshed when moving, and then the rack plate 15 can be used to drive the gear ring 6 to rotate when pushing the shell 5, so as to complete the subsequent positioning of the mold. The middle part of the shell 5 is rotatably connected with four gears 7, and the four gears 7 are all meshed with the gear ring 6. The top of the gear 7 is fixedly connected with a turntable 8, and the top of the turntable 8 is fixedly connected with an eccentric column 9. The middle part of the shell 5 is slidably connected with four connecting rod belts 10, and the eccentric column 9 is located in the middle of the connecting rod belt 10. The outer side of the connecting rod belt 10 is fixedly connected with a slider 11, and the other side of the slider 11 is fixedly connected with a splint 12, and the other side of the splint 12 is fixedly connected with a rubber pad 13.

[0035] Reference Figure 3-Figure 5 , while the shell 5 moves, the gear ring 6 can drive the four gears 7 and the four turntables 8 to rotate simultaneously through the rack plate 15. At this time, the connecting rod belt 10 can drive the slider 11 and the clamping plate 12 to slide through the eccentric column 9, so that the mold can be clamped and positioned, which can improve the effect of hardware stamping and avoid the loss of hardware materials. At the same time, after clamping, the meshing teeth 16 cannot drive the gear ring 6 to rotate. At this time, the meshing teeth 16 will squeeze the rack plate 15 and make the rack plate 15 compress the compression spring 14, so that the shell 5 can clamp the mold and move it to the bottom of the stamping assembly 3. At this time, the stamping of the mold can be completed by driving the stamping assembly 3. The mold can be easily assembled and disassembled by moving the shell 5. At the same time, there is no need for employees to assemble and disassemble the mold under the stamping assembly 3, thereby reducing the risk of replacing the mold. At the same time, the rubber pad 13 can improve the stability of the clamping.

[0036] Reference Figure 3-Figure 5 A slide groove 20 is provided on the top of the shell 5, and the slider 11 is slidably connected to the middle of the slide groove 20. The slider 11 can be restricted by the slide groove 20, so that only the slider 11 can drive the clamping plate 12 to move parallelly, which can improve the positioning accuracy of the shell 5. A displacement component is fixedly connected to the middle of the base 1.

[0037] Reference Figure 3The displacement component includes a motor 17, which is fixedly connected to the middle of the base 1. The output end of the motor 17 is fixedly connected to a screw rod 18, and the outer periphery of the screw rod 18 is threadedly connected to a nut seat 19. The other side of the nut seat 19 is fixedly connected to the outer side of the shell 5. The screw rod 18 can be rotated by driving the motor 17. When the screw rod 18 rotates, the nut seat 19 can drive the shell 5 to move, thereby preventing the shell 5 from being squeezed and rebounding after the movement, and resetting the shell 5. At the same time, there is no need for employees to push the shell 5 to move the shell 5, thereby reducing the labor intensity of employees. A controller is fixedly connected to the outer side of the shell 2, and a start button is fixedly connected to the outer side of the shell 2. The button and the controller are electrically connected, and the controller is electrically connected to the motor 17. By pressing the start button, the controller can control the motor 17 to work, and then the shell 5 can be moved to the bottom of the stamping component 3. At this time, the stamping component 3 can be driven to stamp the hardware.

[0038] Working principle: The screw rod 18 can drive the nut seat 19 to move by driving the motor 17, and then the shell 5 can be moved, and then the shell 5 can be moved in parallel. When the shell 5 moves, the gear ring 6 can drive the four gears 7 and the four turntables 8 to rotate simultaneously through the rack plate 15. At this time, the connecting rod belt 10 can drive the slider 11 and the clamping plate 12 to slide through the eccentric column 9, and then the mold can be clamped and positioned. At the same time, the rubber pad 13 can improve the stability of the clamping, prevent the mold from tilting or shifting when it is squeezed, and then the mold can be replaced conveniently and safely.

[0039] 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.
