An extrusion mechanism 26 is arranged at the other end inside the support platform 2. The extension mechanism 30 cooperates with the extrusion mechanism 26. By rotatably installing the rotating plate 3 on the surface of the support platform 2, the two ends of the rotating plate 3 can be rotatably installed in the laser processing body 1 in turn, thereby improving the efficiency of batch laser processing of the mold surface texture. At the same time, with the cooperation of the extrusion mechanism 26 and the extension mechanism 30, the end face of the rotating plate 3 installed inside the laser processing body 1 will be squeezed by the extrusion plate 22, and the positioning semicircle 5 and the movable semicircle 6 will fit together to realize the positioning of the mold and ensure the stability of the mold during the laser processing process.

[0019] The locking mechanism includes a positioning semicircle 5, which is fixedly installed inside the semicircular port 4. A movable semicircle 6 is movably provided on the side of the positioning semicircle 5. The movable semicircle 6 cooperates with the positioning semicircle 5, and a positioning hole is provided on the surface adjacent to the movable semicircle 6 and the positioning semicircle 5. Both ends of the movable semicircle 6 are fixedly provided with protrusions. The inner wall of the semicircular port 4 is provided with a movable groove 7. The protrusion is slidably engaged in the movable groove 7. The staff can insert the bottom of the mold into the positioning hole between the positioning semicircle 5 and the movable semicircle 6, so that the mold can be installed at the end of the rotating plate 3, which is convenient for the staff to install and disassemble the mold.

[0020] The extrusion mechanism 26 includes a movable seat 21, a top end face of the movable seat 21 is fixedly provided with an extrusion plate 22, a middle end of the inside of the support 2 is fixedly provided with a fixed block 25, a second spring 23 is provided between the movable seat 21 and the fixed block 25, guide columns 24 are provided on both sides of the second spring 23, the end faces of the guide columns 24 are fixedly connected to the movable seat 21, and the surface of the guide columns 24 movably penetrates the fixed block 25. Under the action of the second spring 23 and the guide columns 24, the movable seat 21 can slide inside the support 2, and when the rotating plate 3 rotates, the movable semicircle 6 at one end of the rotating plate 3 is in a vertical state with the extrusion plate 22, and then under the action of the extension mechanism 30, the movable seat 21 will move to one side of the movable semicircle 6, and at this time, the extrusion plate 22 will move the movable semicircle 6 to one end of the positioning semicircle 5, thereby realizing the positioning of the mold and ensuring the stability of the mold during laser processing.

[0021] The inner wall of the open groove 14 is provided with a rack surface 15, and the extension mechanism 30 includes a second gear 16, which is meshed with the rack surface 15. The end of the second gear 16 is installed on the inner wall of the support platform 2 through a rotating shaft, and the other end of the second gear 16 is provided with a rotating cylinder 17. The inner wall of the rotating cylinder 17 is spirally provided with a path groove 18. A telescopic column 19 is movably provided inside the rotating cylinder 17, and a card block is installed at one end of the telescopic column 19 inside the rotating cylinder 17. The card block is movably connected to the path groove 18. When the moving bar 13 moves to the depth of the support platform 2, the rack surface 15 is meshed with the second gear 16, so that the second gear 16 and the rotating cylinder 17 will rotate, and then the card block and the path groove 18 are rotated. Under the action, the telescopic column 19 will extend outward from the inside of the rotating cylinder 17. At this time, the telescopic column 19 has an extrusion effect on the extrusion plate 22, causing the extrusion plate 22 to move in the direction of the movable semicircle 6, thereby realizing the positioning of the mold and ensuring the stability of the mold during the laser processing. At this time, in the extension mechanism 30 at the other end, the surface of the telescopic column 19 will shrink to the inside of the rotating cylinder 17. The extension mechanisms 30 at both ends can have an extrusion effect on the extrusion plate 22. A slide bar is provided at the bottom of the telescopic column 19, and a limiting groove is provided on the inner wall of the support platform 2. The slide bar is clamped in the limiting groove. Under the action of the slide bar and the limiting groove, the telescopic column 19 will not rotate with the rotating cylinder 17, thereby realizing the telescopic movement of the telescopic column 19.

[0022] One end of the extrusion plate 22 close to the telescopic column 19 is set as an arc surface, and when the telescopic column 19 is extended, its end surface is close to the middle of the extrusion plate 22, and the middle of the arc surface is the most convex part. After the telescopic column 19 is extended, its end surface can extrude the middle of the arc surface, and the extrusion plate 22 moves in the direction of the movable semicircle 6 to realize the positioning of the mold.

[0023] The reciprocating mechanism 8 includes a sliding rack 10, which is meshed with a first gear 9. Under the reciprocating sliding operation of the sliding rack 10, the first gear 9 drives the rotating plate 3 to rotate reciprocatingly, so that the two ends of the rotating plate 3 can be rotated and installed in the laser processing body 1 in turn, thereby improving the efficiency of batch laser processing of the surface texture of the mold. The front and rear end surfaces of the sliding rack 10 are fixedly installed with a stopper 11, and the end surface of the stopper 11 is provided with a first inclined surface 27. The moving bar 13 is provided near the end surface of the sliding rack 10. There is a second inclined surface 28, and the first inclined surface 27 corresponds to the second inclined surface 28. When the stopper 11 moves toward one side of the moving bar 13, the first inclined surface 27 has an extrusion effect on the second inclined surface 28, so that the moving bar 13 will move deeper into the support platform 2. A cylinder 31 is installed on the side of the support platform 2, and the output end of the cylinder 31 is connected to the reciprocating mechanism 8. The sliding rack 10 is driven to reciprocate by the cylinder 31. The stoppers 11 at both ends of the sliding rack 10 have an extrusion effect on the moving bars 13 on both sides respectively.

[0024] A guard plate 12 is disposed on the side of the first gear 9 to prevent the stopper 11 from hitting the first gear 9 , thereby protecting the first gear 9 .

[0025] A first spring 20 is provided at one end of the moving bar 13 in the open groove 14, and a side box 29 is fixedly installed inside the support platform 2. The side box 29 is located on one side of the moving bar 13, and a slide groove is provided on the surface of the side box 29. A protrusion is installed in the middle of the moving bar 13, and the protrusion is slidably installed in the slide groove. When the block 11 does not squeeze the sliding rack 10, the moving bar 13 will move to one side of the reciprocating mechanism 8 under the elastic force of the first spring 20. At this time, the telescopic column 19 inside the extension mechanism 30 will shrink to the inside of the rotating drum 17, and under the action of the side box 29, the position of the moving bar 13 is limited, and at the same time, the stability of the moving bar 13 during use is guaranteed.

[0026] Working principle: First, the cylinder 31 drives the sliding rack 10 to reciprocate. Under the reciprocating sliding operation of the sliding rack 10, the first gear 9 drives the rotating plate 3 to rotate reciprocatingly, so that the two ends of the rotating plate 3 can be rotated and installed in the laser processing body 1 in sequence. During the movement of the sliding rack 10, the first inclined surface 27 has an extrusion effect on the second inclined surface 28, so that the moving bar 13 moves deeper into the support platform 2. Then, when the moving bar 13 moves deeper into the support platform 2, the rack surface 15 is meshed with the second gear 16, so that the second gear 16 and the rotating drum 17 rotate, and then under the action of the block and the path groove 18 , the telescopic column 19 will extend outward from the inside of the rotating cylinder 17. At this time, the telescopic column 19 has an extrusion effect on the extrusion plate 22, causing the extrusion plate 22 to move in the direction of the movable semicircle 6, thereby positioning the mold and ensuring the stability of the mold during the laser processing. When the block 11 does not squeeze the sliding rack 10, the movable bar 13 will move to one side of the reciprocating mechanism 8 under the elastic force of the first spring 20. At this time, the telescopic column 19 inside the extension mechanism 30 will shrink to the inside of the rotating cylinder 17. The overall structure has the advantages of simplified process, accurate positioning and high efficiency, thereby improving the efficiency of mass laser processing of mold surface textures.
