[0021] 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.

[0022] See also Figure 1 to Figure 5 In the embodiment of the utility model, a mold processing tooling structure includes a workbench 1 with supporting legs at the bottom, and slide grooves 2 are opened on both sides of the workbench 1. A bidirectional screw 3 is rotatably connected inside one slide groove 2, and a limit rod 9 is fixedly connected inside the other slide groove 2. A clamping arm 4 is connected to the outside of the bidirectional screw 3 and the limit rod 9, and both ends of the clamping arm 4 are slidably connected to the bidirectional screw 3, and the clamping arm 4 is threadedly connected to the bidirectional screw 3; a driving mechanism for driving the bidirectional screw 3 to rotate is installed at one end of the workbench 1, and the driving mechanism is used to drive the two clamping arms 4 to clamp the outer wall of the mold to be processed; the straight rod part of the clamping arm 4 is axially slidably connected to the sliding mechanism, and the sliding mechanism is used to drive the clamped mold to be processed to move axially, and the axial movement direction is perpendicular to the opening direction of the bidirectional screw 3.

[0023] In this embodiment: first, the mold to be processed is placed on the top of the workbench 1, and then the driving mechanism is started, which drives the bidirectional screw 3 to rotate, and the bidirectional screw 3 drives the two clamping arms 4 to move away from each other or move closer to each other. When the two clamping arms 4 move closer to each other, the mold to be processed can be clamped, and when the two clamping arms 4 move away from each other, the clamping of the mold can be cancelled;

[0024] When the two clamping arms 4 move toward each other and approach each other, the two sliding mechanisms are in close contact with the surface of the mold to be processed to achieve a clamping effect. When the axial position of the mold to be processed needs to be adjusted, the sliding mechanism is rotated to cancel the fixation of the sliding mechanism and the clamping arm 4, and then the sliding mechanism can be pushed to drive the mold to be processed to move axially. After the mold to be processed moves to the preset position, the sliding mechanism is rotated in the opposite direction again to limit the sliding mechanism to the outer wall of the clamping arm, so that the mold to be processed can be limited to the current position.

[0025] Please refer to Figure 1 One end of the outer wall of the bidirectional screw 3 is formed with a positive thread, and the other end of the outer wall of the bidirectional screw 3 is formed with a reverse thread. A clamp arm 4 is connected to the positive thread at a location where an internal thread matching the positive thread is formed, and another clamp arm 4 is connected to the reverse thread at a location where an internal thread matching the positive thread is formed.

[0026] In this embodiment, when the bidirectional screw rod 3 rotates, the two clamping arms 4 move toward each other or in opposite directions under the action of the internal threads thereof.

[0027] Please refer to Figure 2 The driving mechanism includes a worm 7 installed on one end of the workbench 1 through a fixed frame, a worm wheel 6 is meshed on the outer periphery of the worm 7, one end of the worm wheel 6 is connected to the bidirectional screw 3, and a forward and reverse motor 8 is installed at the bottom of the fixed frame, and the output end of the forward and reverse motor 8 is connected to one end of the worm 7.

[0028] In this embodiment: by starting the forward and reverse motor 8, the forward and reverse motor 8 drives the worm 7 to rotate. When the worm 7 rotates, the spiral portion of its outer wall squeezes the tooth portion of the outer wall of the worm wheel 6, thereby driving the worm wheel 6 to rotate. The rotating worm wheel 6 can drive the bidirectional screw 3 to rotate, thereby controlling the rotation direction of the forward and reverse motor 8 to achieve clamping or canceling of the two clamping arms 4.

[0029] Please refer to Figure 4 and Figure 5 The sliding mechanism includes a slider 5 slidably connected to the outer wall of the straight rod portion of the clamp arm 4, and a hollow sleeve 10 with a hollow structure is formed at one end of the two sliders 5 away from each other. A stud 11 is threadedly connected to the inner wall of the hollow sleeve 10, and one end of the stud 11 penetrates into the inner cavity of the slider 5. The other end of the stud 11 is fixedly connected to a connecting disk 12, and a plurality of handles 13 equidistantly arranged in the circumferential direction are integrally formed on the outer circumference of the connecting disk 12.

[0030] In this embodiment: when it is necessary to adjust the position of the mold to be processed axially, the handle 13 is pulled to rotate it, and the handle 13 drives the connecting plate 12 to rotate, and the connecting plate 12 drives the stud 11 to rotate. The stud 11 moves outward during the rotation. At this time, the end of the stud 11 is away from the outer wall of the clamping arm 4, and the fixation can be cancelled. Then, the hollow sleeve 10 is pushed to move, and the hollow sleeve 10 pushes the slider 5 to move axially along the straight rod portion of the clamping arm 4. When the mold to be processed moves to the preset position, the handle 13 is pushed in the reverse direction to achieve its reverse rotation. At this time, the end of the stud 11 is tightly pressed on the straight rod portion of the clamping arm 4, fixing the slider 5 at the current position after the movement.

[0031] Please refer to Figure 5 A spherical anti-falling block is formed at one end of the handle 13 away from the connecting disk 12 , and the diameter of the spherical anti-falling block is larger than the diameter of the handle 13 .

[0032] In this embodiment, the provision of the spherical anti-detachment block can prevent the hand from being separated from the handle 13 during the force application process.

[0033] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
