[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] Embodiment 1

[0027] like Figure 1 As shown, a demoulding device of a motorcycle inner tube vulcanizer comprises a frame 1, an upper mold 2 is movably installed in the middle of the upper wall of the inner surface of the frame 1, a hydraulic rod 3 is fixedly installed in the middle of the lower wall of the inner surface of the frame 1, a lower mold 4 is fixedly connected to the upper end of the hydraulic rod 3, a control panel 5 is fixedly installed on the left front end of the frame 1, an ejection assembly 6 is arranged at the front of the lower end of the lower mold 4, and a protective assembly 7 is arranged at the right front end of the control panel 5.

[0028] During the implementation of this embodiment, the inner tube to be processed is placed in the inner cavity of the lower mold 4. At this time, the control panel 5 is used to control the hydraulic rod 3 to move upward, so that the lower mold 4 and the upper mold 2 are molded together, and then the inner tube is processed. After processing, the processed inner tube is ejected by the ejection component 6. At the same time, after the program is adjusted, the control panel 5 can be protected by the protection component 7 to avoid accidental touch.

[0029] Specifically, in order to realize the ejection of the processed motorcycle inner tube from the inner cavity of the lower mold 4, refer to Figure 3 and Figure 4 In this embodiment, the rear end of the connecting plate 67 is fixedly connected to a servo motor 68, and the output end of the servo motor 68 is fixedly connected to a rotating rod 69 through a coupling. Two rollers 610 are fixedly connected to the outer surface of the rotating rod 69, and the upper end of the connecting plate 67 is fixedly connected to the front part of the lower end of the lower mold 4.

[0030] For further information, see Figure 3 and Figure 4 In this embodiment, the lower ends of the two rectangular rods 65 are fixedly connected with connecting ropes 66 , and the ends of the two connecting ropes 66 away from the rectangular rods 65 are wound and connected with the roller 610 .

[0031] For further information, see Figure 3 and Figure 4 In this embodiment, the lower ends of the two rectangular rods 65 are fixedly connected with connecting ropes 66 , and the ends of the two connecting ropes 66 away from the rectangular rods 65 are wound and connected with the roller 610 .

[0032] During the implementation process, the servo motor 68 is started so that the output end of the servo motor 68 drives the rotating rod 69 to rotate, and then drives the roller 610 on the rotating rod 69 to rotate. Under the winding connection, the connecting rope 66 is tightened, and the rectangular rod 65 is pulled to slide in the inner cavities of rectangular hole 1 62 and rectangular hole 2 64 respectively. At this time, the annular block 612 will be pulled to slide on the inner wall of the annular groove 61, and then enter the inner cavity of the annular groove 61, so that the user can put the inner tube to be processed into the lower mold 4.

[0033] For further information, see Figure 3 and Figure 4In this embodiment, springs 611 are sleeved on the outer surfaces of the two rectangular rods 65, and the two ends of the two springs 611 are fixedly connected to the lower end of the circular ring block 612 and the middle part of the upper end of the concave block 63 respectively.

[0034] As can be seen from the above, when the connecting rope 66 is tightened, the spring 611 is in a compressed state under the limiting action of the circular block 612 and the concave block 63. When the inner tube processed inside the lower mold 4 needs to be demolded, the servo motor 68 is reversed to relax the connecting rope 66, and then the circular block 612 is pushed out of the inner tube from the lower mold 4 under the reaction force of the compression of the spring 611.

[0035] The servo motor 68 mentioned above is controlled by a servo control system in the prior art in this solution, which can control the speed, number of rotations and rotation angle of the servo motor 68. In this solution, it is only necessary to make the number of forward and reverse rotations of the servo motor 68 the same.

[0036] Embodiment 2

[0037] This embodiment adds a protection component 7 for protecting the control panel 5 after operation on the basis of the first embodiment, so as to protect the control panel 5 and the buttons thereon after operation.

[0038] Specifically, in order to protect the control panel 5 and the buttons thereon after the operation, refer to Figure 2 and Figure 5 In this embodiment, the protective component 7 includes a lifting ring 77, and a concave groove 71 is opened at the right front end of the control panel 5. The upper and lower walls of the inner surface of the concave groove 71 are rotatably connected to a round rod 72, and the outer surface of the round rod 72 is fixedly connected to a protective shell 73.

[0039] During the implementation process, the protective shell 73 is rotated so that the upper and lower ends of the round rod 72 rotate on the upper and lower walls of the inner surface of the concave groove 71 respectively, and the rotating protective shell 73 covers the front end of the control panel 5 .

[0040] For further information, see Figure 2 and Figure 5 In this embodiment, a fixing belt 74 is fixedly connected to the middle part of the left end of the control panel 5, a Velcro 2 76 is fixedly connected to the left end of the fixing belt 74, a Velcro 1 75 is fixedly connected to the right end of the fixing belt 74, the Velcro 2 76 and the Velcro 1 75 are bonded together, and the front end of the pull ring 77 is fixedly connected to the rear end of the fixing belt 74.

[0041] For further information, see Figure 2 and Figure 5In this embodiment, a concave hole block 78 is fixedly connected to the middle of the left end of the protective shell 73, and the inner surface length of the concave hole block 78 is greater than the outer surface width of the fixing belt 74.

[0042] During the implementation process, the fixing belt 74 is pushed to make the fixing belt 74 pass through the inside of the concave hole block 78. After the fixing belt 74 is tightened, the Velcro 1 75 on the fixing belt 74 is pressed to make the Velcro 1 75 and the Velcro 2 76 adhere to each other, so that the protective shell 73 is fixed on the control panel 5. When the control panel 5 is used, the lifting ring 77 is pulled to make the Velcro 1 75 move away from the Velcro 2 76, the fixing belt 74 leaves the concave hole block 78, and the protective shell 73 is reversed, so that the control panel 5 can be used.
