Figure 1 As shown, when the internal threaded sleeve 2041 is at the top dead center, the upper mold part 7 is separated from the lower mold part 6, as shown in the attached Figure 2 shown.

[0041] Combined with Figure 2 , Attachment Figure 5 , Attachment Figure 6 , Attachment Figure 7 , Attachment Figure 8 , Attachment Fig. 9 , Attachment Fig.10 , Attachment Fig.11 and attached Fig.14 :

[0042] Four evenly distributed demoulding components 9 are arranged under the upper support member 10, and the demoulding components 9 include a slide bar 901 fixedly installed under the upper support member 10, and the four upper mold mounting grooves 703 are each provided with a second slide hole 704 slidably connected to the slide bar 901, and the bottom end of the slide bar 901 is fixedly connected with a column 902, and the column 902 is provided with four evenly distributed grooves 903, and the lower mold mounting groove 603 is provided with an inverted cone trough body 11, and the groove 903 is provided with an adaptive spring block component 904 that can move up and down in the inverted cone trough body 11 and shrink, and the groove 903 is provided with a wedge-shaped demoulding piece 905 that can slide with the shrinkage of the adaptive spring block component 904;

[0043] The groove 903 includes a trapezoidal groove body 9031, a limiting rotating shaft 9032 is provided at the bottom of the trapezoidal groove body 9031, and sliding grooves 9033 are provided on both sides of the top of the trapezoidal groove body 9031. The adaptive spring block assembly 904 includes a special-shaped spring block body 9041 matched with the trapezoidal groove body 9031, a limiting shaft hole 9046 rotatably connected to the limiting rotating shaft 9032 is provided at the bottom of the special-shaped spring block body 9041, and a limiting plate 9042 is provided at the top of the special-shaped spring block body 9041 near the axis of the column 902, and a circular through hole 9043 is provided on the limiting plate 9042, and a spring fixing seat 9044 is rotatably connected in the circular through hole 9043, and a spring 9045 is provided between the spring fixing seat 9044 and the top of the trapezoidal groove body 9031;

[0044] The wedge-shaped demoulding piece 905 includes a wedge-shaped piece body 9051, and sliders 9052 slidably connected to the slide groove 9033 are provided on both sides of the wedge-shaped piece body 9051, and a limiting protrusion 9053 matching with the limiting plate 9042 is provided at the bottom of the wedge-shaped piece body 9051;

[0045] Through the above structure, after the demoulding assembly 9 moves with the upper support member 10, when the column 902 is in the inverted conical trough 11, the four adaptive spring block assemblies 904 and the wedge-shaped demoulding piece 905 are in a contracted state, and the spring 9045 provides pretension. The special-shaped spring block body 9041 cooperates with the limiting shaft hole 9046 and the limiting rotating shaft 9032, so that the top of the special-shaped spring block body 9041 is close to the inner wall of the inverted conical trough 11. At this time, the limiting protrusion 9053 under the wedge-shaped piece body 9051 is driven by the limiting plate 9042 to make the wedge-shaped piece body 9051 and the top edge of the special-shaped spring block body 9041 close to the inner wall of the inverted conical trough 11 be in the same horizontal plane;

[0046] When the column 902 moves upward, as the diameter of the inner wall of the inverted conical trough 11 gradually increases, the top of the shaped elastic block 9041 gradually moves toward the inverted conical trough 11 under the pretension of the spring 9045, thereby driving the wedge-shaped piece 9051 to move toward one side of the inverted conical trough 11, and the attached Fig.14 A ring-shaped rubber part mold is provided, which includes a lower mold installed in the lower mold installation groove 603 and an upper mold installed in the upper mold installation groove 703. When the wedge-shaped sheet 9051 is about to be exposed from the lower mold installation groove 603, the rubber part adhered to the lower mold can be squeezed out of the lower mold.

[0047] Combined with Figure 2 , Attachment Figure 3 , Attachment Figure 6 and attached Fig.14 :

[0048] An upper mold member 7 is provided between the upper support member 10 and the lower mold member 6 and can move with the upper movable seat 3. The upper mold member 7 includes an upper mold seat 701. An upper cross guide groove 702 is provided at the bottom of the upper mold seat 701 to match the lower cross guide groove 602. Upper mold mounting grooves 703 are provided at the four ends of the upper cross guide groove 702. A first sliding hole 705 for the conveying pipe 403 to pass through is provided at the center of the upper cross guide groove 702.

[0049] Three electric telescopic components 8 for individually controlling the upper mold member 7 to move up and down are arranged under the upper movable seat 3. The upper movable seat 3 is a plate body with three extended ends. The electric telescopic components 8 include a rotating seat 801 located at the extended end of the upper movable seat 3. An electric telescopic rod 802 is rotatably connected to the rotating seat 801. A rotating shaft 803 is arranged at the telescopic end of the electric telescopic rod 802. Three shaft seats 804 rotatably connected to the rotating shaft 803 are arranged on the outer circumference of the upper mold seat 701.

[0050] Through the above structure, after the rubber part is formed, the height control component 2 is controlled to separate the upper mold part 7 from the lower mold part 6 through the upper moving seat 3. Figure 2 By controlling the electric telescopic rod 802, the upper mold base 701 can be moved up and down independently. Figure 3 .

[0051] Example 1: Refer to the attached Figure 1 At this time, the upper mold part 7 and the lower mold part 6 are tightly attached, and the raw material enters the storage barrel 401 from the raw material filter 402, and then enters the lower cross guide groove 602 and the upper cross guide groove 702 from the storage barrel 401 through the feeding pipe 403, and then enters the lower mold in the lower mold mounting groove 603. The upper mold part 7, the lower mold part 6 and the upper support part 10 are provided with a heating component to keep the raw material in the storage barrel 401 and the feeding pipe 403 in a liquid state. The heating component is a prior art, so it is not described here in detail;

[0052] After the raw material is formed in the mold, the upper mold part 7 is separated from the lower mold part 6 by the height control component 2. During the separation process, as the horizontal diameter of the inner wall of the inverted conical trough body 11 gradually increases, the top of the special-shaped elastic block body 9041 gradually moves toward the direction of the inverted conical trough body 11 under the pre-tension of the spring 9045, thereby driving the wedge-shaped sheet body 9051 to move toward one side of the inverted conical trough body 11, and the attached Fig.14 A ring-shaped rubber part mold is provided, which includes a lower mold installed in the lower mold installation groove 603 and an upper mold installed in the upper mold installation groove 703. When the wedge-shaped sheet 9051 is about to be exposed from the lower mold installation groove 603, the rubber part adhered to the lower mold can be squeezed out of the lower mold.

[0053] Embodiment 2: After the upper mold part 7 is separated from the lower mold part 6, the rubber part is stuck to the upper mold. Since the temperature of the rubber part is high at this time, it is not easy to remove it by hand. At this time, the electric telescopic component 8 is controlled to extend. Figure 2, so that the upper mold part 7 moves downward alone. At this time, the wedge-shaped sheet 9051 goes around the inner side of the upper mold to the top of the upper mold, and then the electric telescopic component 8 is controlled to shorten, and the upper mold part 7 can be controlled to move upward alone. At this time, the upper mold and the rubber part can be removed as a whole. The upper mold and the upper mold mounting groove 703 are snap-fit ​​installations. This is the existing mode and is not described here. After the rubber part cools down, it can be removed, and then the electric telescopic component 8 is extended to reassemble the upper mold on the upper mold mounting groove 703.

[0054] The present invention and its implementation methods are described above, and such description is not restrictive, and the actual structure is not limited thereto. In general, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can creatively design a structure and implementation method similar to the technical solution, which should fall within the protection scope of the present invention.
