[0025] The existing laser engraving jig lacks strong light protection and is easy to cause damage to human eyes. When working, it is necessary to remove the processed mold 9 and then re-place the mold 9 under the laser head. Misoperation can easily cause damage to the laser opponent. By setting a light shield 2, the light shield 2 covers the entire groove 5, and the strong light is filtered and absorbed by the light shield 2 to protect human eyes. The door 3 is opened, and the damping shafts on both sides of the door 3 allow the door 3 to hover 180 degrees. The processed mold 9 is taken out from the inner side of the mold groove 6, and then the mold 9 to be processed is placed into the inner side of the mold groove 6. The rotating table 10 is pushed and rotated counterclockwise. The rotating table 10 rotates on the bearing, and the limit block 11 is squeezed by the inner wall of the card slot 13. The limit block 11 gradually leaves the card slot 13 and enters the inner side of the limit slot 14. The rotating table 10 continues to rotate, and the roller 19 on the surface of the pressing block 15 contacts the groove 5, and the groove 5 pushes the pressing block 15 to rotate clockwise around the rotating shaft 16 At this time, the torsion spring 17 is forced to shrink, and the pressing block 15 approaches the mold 9 until the pressing block 15 completely enters the inner side of the groove 5, and the pressing block 15 is tightly fitted with the mold 9. Until the rotating table 10 rotates ninety degrees, the limit block 11 comes to the next card slot 13, and the first spring 12 pushes the limit block 11 to enter the inner side of the next card slot 13, and the rotating table 10 stops rotating to wait for the mold 9 to be processed. At the same time, the last processed mold 9 is taken out to complete the operation; by setting a light shield 2, the strong light of the filtered laser is absorbed and filtered to protect human eyes. The rotating table 10 can place four molds 9 at the same time. The mold 9 close to the deep groove 5 is directly below the laser head, and the mold 9 to be processed is placed on the outside of the fixed table 4, far away from the laser irradiation, effectively avoiding misoperation causing laser injury to the hand, and multiple mold slots 6 are rotated and used alternately. The mold 9 to be processed is placed while the laser is working, which greatly improves work efficiency.
