Under the fixation of the fixed plate 321, the slide plate 325 is driven to slide outward, and then the arc plate 326 is driven to expand outward synchronously to fix the inner mold 4. The design of the first bearing 311 and the second bearing 314 can reduce the friction when the first motor 312 rotates and increase the service life. After the inner mold 4 is fixed, the rubber sleeve is put on the outside of the inner mold 4, and the outer mold 6 is driven by the molding mechanism 5 to be pressed. After the pressing is completed, the two outer molds 6 are controlled to separate by the molding mechanism 5, and the first motor 312 is controlled to rotate in the opposite direction to end the fixation of the inner mold 4, and the outer tire and the inner mold 4 can be removed.

[0037] Embodiment 2

[0038] See also Figure 5-7 , and on the basis of the first embodiment, it is further obtained that the forming mechanism 5 includes a separation component 51 and a connection component 52, the separation component 51 is fixedly connected to the front side of the top of the base 1, and the connection component 52 is fixedly connected to the top of the separation component 51;

[0039] The separation component 51 includes a rotating seat 511, which is fixedly connected to the left and right ends of the top of the base 1, and a bidirectional screw 512 is rotatably connected inside the rotating seat 511. The left and right sides of the bidirectional screw 512 are threadedly connected to the threaded seat 513, and the top of the threaded seat 513 is fixedly connected to a connecting plate 514. The front and rear sides of the bottom of the threaded seat 513 are plugged and connected to a cross bar 515. The left and right ends of the cross bar 515 are fixedly connected to the bottom of the inner side of the rotating seat 511, and the right end of the bidirectional screw 512 is fixedly connected to a second motor 516, and the bottom of the second motor 516 is fixedly connected to the right side of the base 1;

[0040] The connecting assembly 52 includes a fixing seat 521, which is fixedly connected to the top of the connecting plate 514. A threaded hole 522 is provided in the middle of the front side of the fixing seat 521. A screw rod 523 is threadedly connected inside the threaded hole 522. A third bearing 524 is fixedly connected to the rear end of the screw rod 523. A clamping plate 525 is fixedly connected to the rear side of the third bearing 524. A vertical rod 526 is fixedly connected to the top and bottom of the front side of the clamping plate 525.

[0041] The front end of the vertical rod 526 is inserted into the front side of the fixing seat 521 , the clamping plate 525 is arranged inside the fixing seat 521 , the rear side of the clamping plate 525 is attached to the front side of the outer mold 6 , and the rear side of the fixing seat 521 is attached to the rear side of the outer mold 6 .

[0042] Furthermore, when the rubber is pressed, the second motor 516 is started. Under the fixation of the two rotating seats 511, the second motor 516 drives the bidirectional screw 512 to rotate. The bidirectional screw 512 drives the threaded seat 513 connected with it to rotate. Because the cross bar 515 restricts the threaded seat 513 from rotating, the threaded seat 513 can only move left and right. When the second motor 516 rotates forward, the bidirectional screw 512 drives the two threaded seats 513 to move toward the middle, and then the connecting plate 514 and the connecting assembly are connected. Component 52 drives the outer mold 6 to press the rubber. After the pressing and forming, the second motor 516 is controlled to reverse and drive the two outer molds 6 to separate, so as to facilitate the subsequent removal of the outer tire. When replacing the outer mold 6, the screw rod 523 is rotated to make the screw rod 523 rotate inside the threaded hole 522. Under the fixation of the third bearing 524 and the vertical rod 526, the clamping plate 525 is driven to move forward to end the fixation of the outer mold 6. During installation, the outer mold 6 is clamped inside the fixing seat 521, and the screw rod 523 is rotated in the opposite direction to fix the outer mold 6.

[0043] In actual operation, when the device is used, the inner mold 4 is first fixed, and the top of the inner base 1 of the inner mold 4 is placed on the top of the arc plate 326, and the first motor 312 is started. The first motor 312 drives the rotating disk 322 to rotate. Under the fixation of the fixed shaft 315, the fixed plate 321 is fixed so that it cannot rotate. When the rotating disk 322 rotates, the slide bar 324 slides outward inside the arc groove 323. Under the fixation of the fixed plate 321, the slide plate 325 is driven to slide outward, and then the arc plate 326 is driven to expand outward synchronously, and the inner mold 4 is fixed. The design of the first bearing 311 and the second bearing 314 can reduce the friction when the first motor 312 rotates, thereby increasing the service life. After fixing the inner mold 4, the rubber is sleeved on the outer side of the inner mold 4, and the second motor 516 is started. Under the fixation of the two rotating seats 511, the second motor 516 drives the bidirectional screw 512 to rotate, and the bidirectional screw 512 will drive the threaded seat 513 connected with it to rotate. Because the cross bar 515 restricts the threaded seat 513 so that it cannot rotate, the threaded seat 513 can only move left and right. When the second motor 516 rotates forward, the bidirectional screw 512 drives the two threaded seats 513 to move toward the middle, and then drives the outer mold 6 to press the rubber through the connecting plate 514 and the connecting assembly 52. ​​After pressing and molding, the second motor 516 is controlled to reverse, driving the two outer molds 6 to separate, so as to facilitate the subsequent removal of the outer tire;

[0044] When replacing the outer mold 6, rotate the screw rod 523 to make the screw rod 523 rotate inside the threaded hole 522, and drive the clamping plate 525 to move forward under the fixation of the third bearing 524 and the vertical rod 526, thereby completing the fixation of the outer mold 6. When installing, clamp the outer mold 6 inside the fixing seat 521, and rotate the screw rod 523 in the opposite direction to fix the outer mold 6.

[0045] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
