[0032] In this way, the guide rod assembly involved in the present invention is installed by inserting the clamping guide sleeve 21 onto the upper rod body 11, and then the upper end of the abutting block 22 is pressed against the upper abutting step 14, and the lower end of the abutting block 22 is pressed against the lower abutting step 15, and the clamping guide sleeve 21 is moved downward so that the abutting block 22 is located in the cavity 211, and finally the mold frame connecting plate 23 is pressed against the lower end of the abutting block 22, and the mold frame connecting plate 23 and the clamping guide sleeve 21 are locked together using screws and other fixings, thereby completing the installation of the guide rod 1 and the clamping assembly 2. The mold frame connecting plate 23 is connected to the mold frame 5. When in use, the guide rod 1 can be lifted and lowered along the guide sleeve under the action of the lifting cylinder. When the guide rod 1 is lifted and lowered, the mold frame 5 is driven to be lifted and lowered synchronously by the clamping assembly 2, so that the formed bricks can be separated from the mold frame 5, which is convenient for the output of the formed bricks. Therefore, the clamping assembly 2 of the present application is easy to connect with the guide rod 1, and the connection process of the mold frame 5 and the guide rod 1 is convenient. The traditional method is to directly weld the mold frame 5 and the guide rod 1 together. The welding process is complicated and there is a weld after welding. After long-term use, it is easy to crack along the weld, causing the mold frame 5 to separate from the guide rod 1.

[0033] Optionally, the clamping guide sleeve 21 includes an integrally formed barrel portion 212, an expansion portion 213 and a connection portion 214, the barrel portion 212 forms a limiting channel 2121 that can move along the upper conductor, one end of the expansion portion 213 is connected to the barrel portion 212, the expansion portion 213 forms a cavity 211, and the connection portion 214 is connected to the other end of the expansion portion 213. By providing the limiting channel 2121, and the limiting channel 2121 has a circular cross-section, and the inner diameter of the limiting channel 2121 is equal to the outer diameter of the upper rod body 11, the clamping guide sleeve 21 is not prone to left and right shaking when the upper rod body 11 moves, and after the mold frame connecting plate 23 is connected to the clamping guide sleeve 21, the mold frame connecting plate 23 is not prone to left and right shaking, so that after the mold frame connecting plate 23 is connected to the mold frame 5, the mold frame 5 is more stable during the lifting process.

[0036] By providing three first abutting blocks 22a, second abutting blocks 22b and third abutting blocks 22c of the same size and shape, it is convenient to uniformly produce the abutting blocks 22 and reduce the production cost. During installation, the first abutting blocks 22a, second abutting blocks 22b and third abutting blocks 22c are respectively attached to the middle rod body 12 in sequence, so that the upper ends of the first abutting blocks 22a, second abutting blocks 22b and third abutting blocks 22c are pressed against the upper abutting step 14, and the lower ends of the first abutting blocks 22a, second abutting blocks 22b and third abutting blocks 22c are pressed against the lower abutting step 15, thereby completing the installation of the abutting blocks 22, and the installation of the abutting blocks 22 is relatively convenient.

[0037] In this example, a connection locking assembly 3 for connecting with the mold frame 5 is provided on the mold frame connection plate 23 . By providing the connection locking assembly 3 , it is convenient to connect with the mold frame 5 .

[0038] Specifically, the connecting locking assembly 3 includes a locking screw, a compression spring and a locking nut. The locking screw is passed through the mold frame connecting plate 23, and the compression spring is sleeved on the locking screw. One end of the compression spring abuts against the lower side of the mold frame connecting plate 23. The locking nut is connected to the lower end of the locking screw, and the locking nut abuts against the other end of the compression spring.

[0039] During installation, the locking screw is passed through the mold frame 5 and the mold frame connecting plate 23 and then connected to the locking nut. Since one end of the compression spring abuts against the lower side of the mold frame connecting plate 23, the locking nut abuts against the other end of the compression spring, so that the mold frame 5 has a buffering effect when it is lifted or lowered, preventing the mold frame 5 from being directly hit and damaged.
