[0031] First, the user places the device at the position where it needs to work, and then sprays the mold release agent in the mold, and then starts the air pump 8, and the air pump 8 supplies air to the air pipe 9, so that the rubber inflation inner membrane 7 expands, and the expansion of the rubber inflation inner membrane 7 plays the role of the mold inner membrane, and then the user starts the electric telescopic rod 3 to extend downward through the controller, so that the upper mold 4 is docked with the lower mold 2, and then the prepared material is injected into the mold through the injection port 19. After the material is cooled into a finished tire, the user starts the electric telescopic rod 3 to shrink upward through the controller, and the upper mold 4 moves upward. At this time, the upper mold 4 is demolded from the finished tire, and then the user starts the cylinder 5 to extend upward through the controller, so that the cylindrical base 6, the rubber inflation inner membrane 7 and the finished tire move upward, thereby realizing the demolding between the finished tire and the lower mold 2, and then the user starts the air pump 8, so that the air pipe 9 inhales air, so that the rubber inflation inner membrane 7 shrinks, thereby realizing the demolding between the rubber inflation inner membrane 7 and the finished tire;

The cylinder 5 drives the cylindrical base 6 and the shrunken rubber inflated inner membrane 7 to move downward, and the finished tire product may remain on the unloading rack 13. The servo motor 10 rotates forward to move the unloading rack 13 to the right, so that the whole process of unloading is completed, which saves time and effort and is simple to operate.
