An end plate 704 is fixedly disposed at one end of the gripping rod 703 for limiting the position.

[0027] The main part of the mold is the welding pipe mold 4. The welding pipe mold 4 and the top plate 5 are fixed to the outer end of the fixed column 9 by threaded installation. When disassembling and replacing, the top plate 5 is first disassembled, and the plug-in block 701 is inserted into the first installation groove 11 at the top of the top plate 5, so that the two force components 7 are installed and fixed on the top of the top plate 5. Then, the hand holds the outer end of the grip rod 703, rotates the grip rod 703 and drives the force component 7 to rotate around the center of the top plate 5 as a whole. The force component 7 is connected to the top plate 5, and the top plate 5 is also driven. The top plate 5 rotates relative to the fixed column 9. As a result, the top plate 5 is gradually separated from the fixed column 9, and the disassembly of the top plate 5 is completed. This disassembly method is easier to exert force and more convenient. During the rotation process, the grip rod 703 can also be moved to make the grip rod 703 slide relative to the slide seat 702, so as to adjust the rotating force arm during operation. The larger the force arm, the less effort is required, making it easier to disassemble the top plate 5. After disassembling the top plate 5, the force assembly 7 is separated from the top plate 5, and then installed in the second mounting groove 13 at the top of the welding pipe mold 4 in the same way, and the welding pipe mold 4 is driven to rotate in the same way to disassemble the welding pipe mold 4.

[0028] After the top plate 5 is disassembled, it is necessary to move the top plate 5. Figure 1 , 2 As shown in 4, the top plate 5 is provided with a mounting hole 10 which passes through the top plate 5, and the top plate 5 is threadedly connected with the fixing column 9 through the mounting hole 10, and a cavity is opened at the top of the fixing column 9.

In the installed state, the lifting ring 6 is folded and hidden inside the annular groove. The lifting ring 6 is unfolded by pulling the protrusion, and then the disassembled top plate 5 can be lifted by the lifting ring 6 for transportation.

[0032] When driving the top plate 5 and the pipe welding die 4 to rotate, the fixing column 9 needs to be fixed. Figure 1 , 5As shown, a base 1 is fixedly provided at the bottom end of the fixing column 9, and two handles 3 are fixedly provided at the outer end of the base 1 for easy hand holding, and an anti-slip sleeve is fixedly provided at the outer end of the handle 3.
