[0048] The limiting column 4 and the support 2 are slidably connected left and right. A left and right adjustment mechanism 5 is provided between the limiting column 4 and the support 2. A clamping component 6 with adjustable height is provided on the limiting column 4.

[0049] The left and right adjustment mechanism 5 is used to drive the two limiting columns 4 to move closer or further away simultaneously.

[0050] The clamping assembly 6 includes a connecting seat 61, a rotary cylinder 62, a reversing valve 63, and a mold limiting finger 64;

[0051] The connecting seat 61 is slidably connected to the limiting column 4, and a height adjustment mechanism 7 is provided between the connecting seat 61 and the limiting column 4;

[0052] The corner cylinder 62 and the reversing valve 63 are mounted on the connecting seat 61. The driving end of the corner cylinder 62 is connected to the mold limiting finger 64. The corner cylinder 62 and the reversing valve 63 are arranged in a one-to-one correspondence. The corner cylinder 62 is connected to the compressed air source (not shown in the figure) through the reversing valve 63.

[0053] The mold limiting finger 64 is used to hold the clamping position 101 of the mold 10.

[0054] In this embodiment, the rotating mechanism 3 controls the support 2 to rotate coaxially with the base 1, thereby driving the mold 10 on the support 2 to rotate. This allows maintenance personnel to perform maintenance on the mold 10 in a comfortable and suitable position, reducing the need for frequent movement of maintenance personnel, improving maintenance efficiency and convenience, and reducing maintenance difficulty.

[0055] In this embodiment, the combination of the left and right adjustment mechanism 5 and the height adjustment mechanism 7 allows the two limiting columns 4 to move closer or further apart synchronously, and the height position of the clamping assembly 6 to be adjusted, thereby satisfying the clamping and fixing of molds 10 of different sizes and specifications. This design has a wide range of applications and improves practicality.

[0056] In this embodiment, a clamping assembly 6 consisting of a reversing valve 63 and a corner cylinder 62 is used to replace the existing manually adjustable limiting finger structure. After the mold 10 is placed in place, the reversing valve 63 is controlled to drive the corner cylinder 62 to drive the mold limiting finger 64 to clamp or release the mold 10 according to the rotation and extension action, which is convenient and quick to operate.

[0057] Furthermore, such as Figure 1 , 2 As shown, in order to improve the stability between the support 2 and the base 1 while rotating, the rotating mechanism 3 includes a rotating drive assembly 31 and an outer support assembly 32.
