Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-4 The utility model provides a technical solution: a bent pipe demolding structure, including an operating table 1, an operating table 1 with a cylinder 2 embedded in one side, and a pneumatic telescopic arm 3 is provided inside the cylinder 2, the other end of the pneumatic telescopic arm 3 is connected to the operating block 4, and the two sides of the operating block 4 are respectively provided with a limit frame 5 on the operating table 1, and the other end of the operating block 4 is respectively provided with two groups of fixed boxes, and a servo motor 6 is provided in the fixed box, and the servo motor 6 is provided with an output shaft, and the other end of the output shaft is connected to the motor box, and the motor box is provided with a rotating rod on the other side, and the other end of the rotating rod is inserted into the other group of fixed boxes. It should be additionally explained that the other end of the pneumatic telescopic arm 3 is connected to the operating block 4 through multiple groups of connecting rods, thereby ensuring that the operating block 4 can drive the core rod 10 to move within a predetermined arc trajectory.

[0019] Furthermore, the motor 7 forms a rotating structure through the output shaft, the rotating rod and the limit frame 5 under the action of the servo motor 6, so that the used core rod 10 can be flipped as a whole under the action of the servo motor 6, thereby facilitating regular cooling, lubrication and other operations on the core rod 10.

[0020] The motor box is provided with a motor 7 inside, and the motor 7 is provided with an output shaft. The other end of the output shaft is connected to a fixed plate 8, and a rotating block 9 is provided on the fixed plate 8. The rotating block 9 is inserted into the core rod 10, and the other end of the core rod 10 is also inserted with a rotating block 9, and the other end of the rotating block 9 is also connected to the fixed plate 8. A fixed block is provided on the fixed plate 8 at the other end of the core rod 10, and a bent pipe 11 is sleeved on the outside of the core rod 10.

[0021] Furthermore, under the action of the motor 7, the fixed plate 8 forms a rotating structure through the output shaft, the rotating block 9 and the core rod 10, so that after the bent pipe 11 is formed, the rotating fixed plate 8 can assist its two ends to be quickly demolded, thereby facilitating the subsequent demolding of the entire bent pipe 11.

[0022] A cooling fan 12 is provided on the operating table 1 behind the limiting frame 5 , and a wire 13 is provided on the cooling fan 12 . The other end of the wire 13 is connected to an operator 14 , and the operator 14 is provided on the upper end surface of the operating table 1 .

[0024] Working principle: When using the elbow demoulding structure, first, the motor 7 can be started after the elbow is formed. The motor 7 drives the fixed plate 8 to rotate through the output shaft. At the same time, the other end of the core rod 10 can drive the fixed plate 8 to rotate through the fixed block, so that the core rod 10 and the two ends of the elbow 11 can be quickly demoulded through the rotating fixed plate 8, thereby ensuring the subsequent overall demoulding effect of the elbow 11; after the demoulding of both ends of the elbow 11 is completed, the cylinder 2 can be started, so that the pneumatic telescopic arm 3 drives the operating block 4 to move within a predetermined trajectory, so that the core rod 10 can be pulled outward through the operating block 4, and the elbow 11 can be quickly demoulded. To ensure that the bent tube 11 can be demoulded as a whole, the servo motor 6 can be started after the demoulding of the bent tube 11 is completed, thereby driving the core rod 10 to flip as a whole through the output shaft and the rotating rod, thereby facilitating regular application of lubricating oil to the core rod 10 as a whole, so as to ensure the demoulding efficiency between the bent tube 11 and the core rod 10; after the flipping of the core rod 10 is completed, the cooling fan 12 can be started by the operator 14 to work, so as to regularly cool the core rod 10 as a whole through the cooling fan 12, thereby avoiding the high temperature caused by the long-term use of the core rod 10 affecting the demoulding efficiency of the subsequent bent tube 11. This is the use process of the bent tube demoulding structure.
