One end of the threaded rod 22 extends to the outside of the shell 1 and is equipped with a handle for easy rotation. The movable plate 9 is threadedly sleeved on the threaded rod 22. The threaded rod 22 is rotated to achieve a small range of movement of the movable plate 9. One side of the movable plate 9 is in contact with the side wall of the shell 1, so as to avoid the movable plate 9 from rotating with the threaded rod 22 during the rotation of the threaded rod 22.

[0028] Working principle:

[0029] When using the optical precision mold cleaning jig, the handle above the support plate 7 is rotated until the slider 20 and the rotating roller 6 are adjusted to a height suitable for the current mold, and then the mold is placed on the support plate 7. The mold drives the support plate 7 and the L-shaped toothed plate 8 to press down, and thereby drives the gear 11 to rotate. The gear 11 then drives the two racks 4 in the same clamping unit 2 to approach each other until the two rotating rollers 6 on the support plate 7 clamp the mold and fix it, and then the mold can be cleaned. During the cleaning process, the handle is turned, and the threaded rod 22 rotates and drives the movable plate 9 and the support plate 7 to move. At this time, the support plate 7 cooperates with the rotating roller 6 to realize the rotation of the mold, and the mold can be cleaned in all directions. After completion, the mold can be picked up vertically and taken out, and the entire use process of the optical precision mold cleaning jig is completed.
