The locking device includes a first fixed block 3 and a second fixed block 4. The first fixed block 3 is fixedly connected to the side wall of the first mold 1, and the second fixed block 4 is fixedly connected to the side wall of the second mold 2 and its position corresponds to the first fixed block 3. The second fixed block 4 is provided with a second screw groove 401, and a screw 5 is rotatably connected in the second screw groove 401. A fastening plate 6 is threadedly connected to the screw 5, and a threaded hole 604 matching the screw 5 is provided on the fastening plate 6. The fastening plate 6 is meshed with the screw 5 through the threaded hole 604. A locking block 7 is rotatably connected to the fastening plate 6 close to the second fixed block 4. A first screw groove 302 is provided on the first fixed block 3, and a rectangular groove 301 matching the locking block 7 is provided on the top of the first fixed block 3.

[0023] By setting a locking device, this device can quickly lock or open the first mold 1 and the second mold 2, thereby improving the efficiency of the staff and facilitating the operation of the staff. In addition, by setting a fastening plate 6, a locking block 7 and a rectangular groove 301, the locking block 7 can be driven into the rectangular groove 301 after rotating the fastening plate 6, thereby further clamping the position of the screw rod 5, thereby improving the stability and locking effect of the locking device, preventing the screw rod 5 from loosening after long-term use, and meeting the user's use needs.

[0024] The inner wall of the second screw groove 401 is rotatably connected with a rotating shaft 402, the outer wall of the rotating shaft 402 is sleeved with a shaft sleeve 403, the outer wall of the shaft sleeve 403 is fixedly connected with a sleeve 404, and the end of the screw 5 close to the second fixed block 4 is fixedly connected in the sleeve 404. The screw 5 is specifically rotatably connected to the second fixed block 4 through the rotating shaft 402, the sleeve 403 and the sleeve 404. By setting the rotating shaft 402, the sleeve 403 and the sleeve 404, the screw 5 can be rotatably connected to the inner wall of the second screw groove 401, thereby facilitating the locking or unlocking of the locking device.

[0025] One end of the screw rod 5 away from the second fixing block 4 passes through the locking block 7 and the fastening plate 6 in sequence and is fixedly connected with a handle 501 . The handle 501 is provided to facilitate the user to pull the screw rod 5 .

[0026] Two sets of turning handles 601 are fixedly connected to one side of the fastening plate 6 away from the locking block 7. The two sets of turning handles 601 are symmetrically distributed up and down about the threaded hole 604. The two sets of turning handles 601 are arranged to facilitate the user to rotate the fastening plate 6, thereby facilitating the fastening plate 6 to push the locking block 7.

[0027] A rotating tube 602 is fixedly connected to one side of the fastening plate 6 away from the rotating handle 601 , and a clamping ring 603 is fixedly connected to one end of the rotating tube 602 away from the fastening plate 6 .

[0028] A rotation groove 701 matching with the retaining ring 603 and the rotating tube 602 is provided inside the locking block 7. The locking block 7 is rotatably connected to the fastening plate 6 through the rotation groove 701, the retaining ring 603 and the rotating tube 602. By setting the rotation groove 701, the rotating tube 602 and the retaining ring 603, the locking block 7 can keep itself stationary and move downward under the driving action of the rotation of the fastening plate 6. When the fastening plate 6 keeps spirally moving upward or downward, the locking block 7 can rotate without rotating with the rotation of the fastening plate 6, thereby ensuring that the locking block 7 can be smoothly inserted into the rectangular groove 301, limiting the rotation of the screw rod 5 around the rotating shaft 402, and ensuring the stability of the locking device.

[0029] The locking block 7 is provided with a round hole 702 matching the screw rod 5 . The round hole 702 can be provided to allow the locking block 7 to slide on the outer wall of the screw rod 5 .

[0030] Working principle: When the user needs to lock the mold, firstly, the first mold 1 and the second mold 2 are aligned and locked. At this time, the positions of the first fixing block 3 and the second fixing block 4 are aligned. The handle 501 is pulled, and the handle 501 drives the screw rod 5 to move and rotate along the rotating shaft 402. The screw rod 5 drives the sleeve 404 to rotate, and the sleeve 404 drives the sleeve 403 to rotate on the outer wall of the rotating shaft 402. When the screw rod 5 rotates to the first screw rod groove 302, the handle 601 is rotated. Turn the fastening plate 6, and the fastening plate 6 then moves spirally downward along the screw rod 5, the fastening plate 6 drives the rotating tube 602 to rotate, the rotating tube 602 drives the retaining ring 603 to rotate in the rotating groove 701, the fastening plate 6 pushes the locking block 7 to move downward, when the fastening plate 6 pushes the locking block 7 to move into the rectangular groove 301, the locking block 7 slides downward along the inner wall of the rectangular groove 301, and the fastening plate 6 continues to be rotated until it is tightened, the locking of the device can be completed, when the mold needs to be opened, the locking process can be reversed.

[0031] By setting a locking device, this device can quickly lock or open the first mold 1 and the second mold 2, thereby improving the efficiency of the staff and facilitating the operation of the staff. In addition, by setting a fastening plate 6, a locking block 7 and a rectangular groove 301, the locking block 7 can be driven into the rectangular groove 301 after rotating the fastening plate 6, thereby further clamping the position of the screw rod 5, thereby improving the stability and locking effect of the locking device, preventing the screw rod 5 from loosening after long-term use, and meeting the user's use needs.
