[0019] The adjusting mechanism includes an installation cavity 9, a first servo motor 10, a threaded rod 11, a threaded sleeve 12, a movable cavity 13 and a limiting structure. The installation cavity 9 is installed on one side of the right side plate 4. The first servo motor 10 is installed at one end of the installation cavity 9. The threaded rod 11 is installed inside the installation cavity 9. The output end of the first servo motor 10 is connected to one end of the threaded rod 11. The outer wall of the threaded rod 11 is provided with a threaded sleeve 12. The outer wall of the threaded sleeve 12 is fixedly installed with a movable cavity 13. One end of the movable cavity 13 extends to the inner side of the right side plate 4. One end of the movable cavity 13 is connected to one end of the movable plate 5. When in use, the first servo motor 10 is started to drive the threaded rod 11 to rotate, thereby driving the threaded sleeve 12 to move, and then under the limitation of the limit groove 14 and the limit block 15, the threaded sleeve 12 is used to drive the movable cavity 13 to move, and then the mold cover 6 is driven to move, so that the mold body 3 and the mold cover 6 are molded together. When unloading is required, the first servo motor 10 is started to reverse it, driving the mold cover 6 to separate from the mold body 3. At this time, the material can be taken out from the inside of the mold body 3, making the rotational molding mold more convenient and efficient when in use, and also reducing the labor intensity of workers, thereby greatly improving the practicality of the mold when in use.

A groove body is provided inside the positioning seat 18. The groove body and the guide rail 19 are adapted to each other. When in use, the second servo motor 22 is started to drive the driving gear 21 to rotate. Since the transmission gear ring 20 and the driving gear 21 are meshed with each other, the transmission gear ring 20 is used to drive the mold body 3 and the mold cover 6 to rotate under the limit of the positioning seat 18 and the guide rail 19, so that the materials of the mold body 3 and the mold cover 6 can be rotationally molded, thereby greatly improving the working efficiency of the mold when in use.

[0023] Working principle: first, add the material into the mold body 3, then start the first servo motor 10 to drive the threaded rod 11 to rotate, so as to drive the threaded sleeve 12 to move, and then under the limit of the limit groove 14 and the limit block 15, the threaded sleeve 12 is used to drive the movable cavity 13 to move, and then the mold cover 6 is driven to move, so that the mold body 3 and the mold cover 6 are molded together. At this time, the mold body 3 and the mold cover 6 are positioned by the fixed pin 7 and the fixed seat 8, and then the second servo motor 22 is started to drive the active gear 21 to rotate. Since the transmission gear ring 20 and the active gear 21 are meshed with each other, the mold body 3 and the mold cover 6 are driven to rotate by the transmission gear ring 20 under the limit of the positioning seat 18 and the guide rail 19. At this time, the guide block 17 rotates inside the guide groove 16, so that the mold body 3 and the mold cover 6 are more stable when rotating. When unloading is required, the first servo motor 10 is started to reverse it, driving the mold cover 6 to separate from the mold body 3, and the material can be taken out from the inside of the mold body 3.
