[0002] An end mold is a device used to fix or support pipes, pipe fittings or other workpieces. End molds are usually used in the installation, processing or transportation of pipes. They can help fix the position of the pipes, prevent them from moving or deforming, and ensure the safety and stability of the pipes. Common types of end molds include: pipe port support molds, pipe port fixing molds, pipe port clamping molds, pipe port closing molds, and pipe port adapter molds. The pipe port fixing mold is used to fix the pipe port to prevent the pipe from falling off or moving. It is usually used in the processing and welding of pipes.

[0003] In the welding of pipelines, two pipelines to be welded are usually fixed and the ports are aligned, so that the welder can weld the two pipelines. However, after the pipelines are fixed, it is not convenient to rotate the pipelines during welding, which also makes it inconvenient to operate the pipelines during welding, reducing the welding efficiency. In addition, after the pipelines are fixed by equipment or devices, there may be a disadvantage that the workers have a small operating space during welding, and it is easy to touch the equipment or parts that fix the pipelines during welding. Therefore, it is necessary to design a fixed end mold for the pipe end with good positioning and fixing effect. Utility Model Content

[0025] During specific use, the row pipe is placed on the first rotating shaft 7 of the inner bottom wall of the fixed platform 5. When the bidirectional screw 4 rotates, it performs threaded motion with the movable frame 9 and drives the two movable frames 9 to move closer to each other in the slide groove 8, and the row pipe is fixed by the second rotating shaft 11. When the threaded rod 12 rotates, it drives the top frame 13 to move downward. At this time, the fixing bar 131 and the fixed platform 5 are in sliding motion, and the row pipe is pressed down and fixed from above by the third rotating shaft 14. Since the first rotating shaft 7, the second rotating shaft 11 and the third rotating shaft 14 can all rotate, the row pipe can also rotate when the row pipe is moved, which is convenient for the rotation of the row pipe when the row pipe is fixed for welding.

[0026] In this embodiment, one end of the bidirectional screw rod 4 passes through the inner wall of the connecting seat 3 and extends to the front surface of the connecting seat 3 , and one end of the bidirectional screw rod 4 is fixedly connected to a rotating disk 15 .

[0036] Working principle: In use, the row of pipes is placed on the first rotating shaft 7 of the inner bottom wall of the fixed platform 5. When the rotating disk 15 is rotated, the bidirectional screw 4 can be driven to rotate. When the bidirectional screw 4 rotates, it performs a threaded motion with the movable frame 9 and drives the two movable frames 9 to move closer to each other in the slide groove 8, and the row of pipes is fixed by the second rotating shaft 11. When the wheel 16 is rotated, the threaded rod 12 can be driven to rotate through the wheel 16. When the threaded rod 12 rotates, it drives the top frame 13 to move downward. At this time, the fixing bar 131 and the fixed platform 5 are in sliding motion, and the third rotating shaft 14 is used to press the row pipe downward and fix it from above. Since the first rotating shaft 7, the second rotating shaft 11 and the third rotating shaft 14 can all rotate, the row pipe can also rotate when it is moved, which is convenient for rotating the row pipe when the row pipe is fixed for welding. When the armrest plate 19 is rotated, the roller 17 can be driven to engage with the movable seat 2, so that the movable seat 2 can be extended from the base 1 through the universal self-locking wheel 18, thereby increasing the distance between the two fixed platforms 5, so that the operator can have more operating space when welding the two row pipes.
