The motor 14 has the function of providing rotational power to the threaded rod 15, and then the rotation function of the threaded rod 15 is realized by providing power through the motor 14.

[0045] For details, please refer to Figure 1 - Figure 4 A threaded rod 15 is rotatably connected inside the motor 14 , and an ejector 16 is rotatably connected to the circumferential surface of the threaded rod 15 .

[0049] The working principle and use process of the utility model: the use process of the device is as follows: first, the user holds the rotating rod 10, and then rotates the rotating rod 10, and then the rotating rod 10 starts to drive the circular cutting blade 9 directly below the support platform 8 to start rotating, and then the circular cutting blade 9 starts to continuously cut the tire surface in the mold shell 11 until there is no resistance, and then the user holds the rotating rod 10 to lift the support platform 8, and then the first lifter 5 will also be lifted and lowered in the second lifter 6 at the same time, and then the support platform 8 is rotated as a whole, and then the rotation is achieved by cooperating with the rotating shaft 4 set in the assisting rotator 2, and then the support platform 8 is rotated as a whole out of the mold shell 11, and then the user controls and presses the button on the control panel 18, and then activates the motor 14, and then the motor 1 4 starts to drive the threaded rod 15 to start rotating, and then the ejector 16 is driven by the threaded rod 15 to continuously move upward, and at the same time the slider 17 also starts to slide upward in the first fixer 12, and then the ejector 16 ejects the tire mold in the mold shell 11, and then the use of the device is completed. By using the present device, the problem that the jacking mechanism of the traditional tire mold cannot solve that the tire is easy to stick to the mold when ejecting the tire model is solved. In order to ensure the smoothness and integrity of the ejection process, it is usually necessary to cut the tire around first.
