[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Example 1

[0019] Reference Figure 1-3 A processing fixture for a mold base positioning sleeve comprises a base plate 1, a vertical plate 6 is fixedly connected to the base plate 1, a support shaft 12 is arranged on the vertical plate 6, a rotating shaft 10 is rotatably connected to the supporting shaft 12 through a bearing, two external threads are arranged at both ends of the rotating shaft 10, the thread directions of the two external threads are opposite, and abutment blocks 7 are threadedly penetrated and connected to the two external threads, and the abutment blocks 7 are positioned by a positioning mechanism. When the mold base positioning sleeve is clamped, the inner and outer walls of the mold base positioning sleeve are abutted and fixed by using two abutment blocks 7 to clamp the mold base positioning sleeve, so that the inner wall of the mold base positioning sleeve is supported, thereby preventing the mold base positioning sleeve from being dented when clamping, and avoiding damage to the mold base positioning sleeve.

[0020] The positioning mechanism includes a positioning column 8, which is fixedly connected to the support shaft 12 and passes through the abutment block 7. The positioning column 8 is designed to limit the abutment block 7 and prevent the abutment block 7 from rotating.

[0021] The rotating shaft 10 is fixedly connected with a rotating block 9, and the rotating block 9 plays a grasping role, so that the rotating shaft 10 can be grasped and driven to rotate, and the position of the abutment block 7 on the external thread can be adjusted.

[0022] When in use, the mold base positioning sleeve is placed between the two abutment blocks 7, and the rotating shaft 10 is rotated to adjust the position of the abutment block 7 on the external thread, so that the two abutment blocks 7 can move toward or away from each other, and the mold base positioning sleeve is clamped to support the inner wall of the mold base positioning sleeve clamping position, thereby preventing the inner wall from being dented.

[0023] Example 2

[0024] In Example 1, the mold base positioning sleeve cannot be rotated, and different positions are processed. Figure 1-3 As another preferred embodiment of the utility model, on the basis of embodiment 1, the support shaft 12 is rotatably connected to the vertical plate 6 through a bearing, a gear 5 is fixedly connected to the support shaft 12, a rack 4 is meshed on the gear 5, and the rack 4 is adjusted by a lifting mechanism, and the lifting mechanism is a hydraulic cylinder 3, one end of the hydraulic cylinder 3 is fixedly connected to the bottom plate 1, and the other end is fixedly connected to the rack 4. The hydraulic cylinder 3 is extended and retracted to drive the rack 4 to move, thereby driving the gear 5 to rotate, thereby driving the support shaft 12 to rotate, and the mold base positioning sleeve is fixed on the support shaft 12, so that the mold base positioning sleeve is rotated, so as to process the mold base positioning sleeve at different positions. When it is necessary to fix the rotation angle, the hydraulic cylinder 3 is height-fixed, and the rack 4 is fixed, thereby fixing the gear 5, and fixing the rotation angle of the mold base positioning sleeve.

Since force will be applied to the mold base positioning sleeve during processing, the support rib 11 is designed to support the support shaft 12, thereby preventing the support shaft 12 from bending and being damaged during support.

[0027] Example 4

[0028] Reference Figure 1-3 As another preferred embodiment of the utility model, on the basis of embodiment 1, a collecting box 2 is placed on the bottom plate 1 to prevent debris from falling into the bottom plate 1 during processing, so as to collect the processed debris.
