The third gear 14 meshes with the second gear 12. A U-shaped frame 15 is fixedly installed on the back of the rotating rod 13.
[0024] By starting the hydraulic cylinder 8, the telescopic movement of the output shaft of the hydraulic cylinder 8 drives the rectangular block 10 and the U-shaped frame 15 to adjust in the vertical direction. Then start the second motor 11. The rotation of the output shaft of the second motor 11 drives the second gear 12. The second gear 12 meshes with the third gear 14 to drive the third gear 14 to rotate. The third gear 14 drives the rotating rod 13 to rotate. The rotating rod 13 drives the U-shaped frame 15 to rotate and adjust. By combining the two adjustments, different processing requirements can be achieved. Compared with traditional devices, since two directions can be adjusted simultaneously, the working position and direction can be flexibly adjusted in a complex working environment to meet diverse processing requirements, thus significantly improving work efficiency.
[0025] The staff first starts the first motor 5. The rotation of the output shaft of the first motor 5 drives the first gear 7 to rotate. The first gear 7 meshes with the tooth groove 4 to drive the rotating table 3 to rotate, so as to rotate the equipment out. After clamping the mold, it is rotated into the housing 2. By starting the hydraulic cylinder 8, the telescopic movement of the output shaft of the hydraulic cylinder 8 drives the rectangular block 10 and the U-shaped frame 15 to adjust in the vertical direction. Then by starting the second motor 11, the rotation of the output shaft of the second motor 11 drives the second gear 12.

[0027] By starting the motor three 16, the output shaft of the motor three 16 rotates to drive the bidirectional screw 17 to rotate, and the rotation of the bidirectional screw 17 drives the two flexible clamping blocks 18 to move closer to or away from each other, so as to cope with molds of different sizes. Compared with traditional devices, the material and design of the flexible clamping block 18 can ensure that a stable clamping force is provided when clamping the mold, preventing the mold from shaking or shifting during the processing, thereby ensuring the processing accuracy and processing quality. Through the movement of the flexible clamping block 18 approaching or moving away from each other, the clamping width can be flexibly adjusted to adapt to molds of different sizes, so that the equipment can handle more types of molds, thereby improving the versatility and adaptability of the equipment.

[0032] Four spring damping rod assemblies 9 are respectively arranged at the four corners of the rectangular block 10 to form a four-point support structure, which can provide a more uniform and stable support force and ensure the balance and stability of the device during rotation and clamping.
[0033] A flexible clamping block 20 is fixedly installed on the top of the operating platform 1 , and a movable groove 21 is opened on the top of the operating platform 1 .
[0034] By providing the movable groove 21, sufficient space is provided for the mold frame 15, so that it can rotate unhindered, reducing the rotation difficulty or jamming problems caused by structural limitations, and ensuring the smoothness of the processing process.
