Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a device for preparing a nitrile rubber cold-resistant sealing ring includes: a base plate 20, which is triangular in shape. A servo motor is installed at the bottom of the base plate 20, and a lower mold 21 is provided above the base plate 20. The servo motor is electrically connected to a corresponding power supply. The base plate 20 is installed on a vulcanizing machine body. The upper mold on the vulcanizing machine body is aligned with the upper part of the pressure-resistant plate 36. This is existing technology and will not be described in detail here.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a rotating structure is installed on the top of the substrate 20 to adjust the position of the lower mold 21. The rotating structure includes a rotating block 30, a fixed frame 31, a rotating component 32, and a pin 33. The rotating block 30 is rotatably connected to the top center of the substrate 20. The fixed frame 31 is fixedly connected to the outer wall of the rotating block 30. The rotating component 32 is rotatably connected between each set of symmetrical fixed frames 31. The pin 33 is symmetrically fixedly connected to both sides of each rotating component 32. The lower mold 21 is fixedly connected to the wall of the rotating component 32. The rotating block 30 can drive the lower mold 21 to rotate on the top of the substrate 20.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the rotating block 30 is an equilateral triangular plate. The retaining frames 31 are symmetrically fixedly connected to each outer wall surface of the rotating block 30. Each retaining frame 31 has a circular groove on its wall surface to accommodate the rotation of the insert post 33. The rotating component 32 is a block with a semi-capsule-shaped cross-section. The spacing between the symmetrical retaining frames 31 can accommodate the dimensions of both sides of the rotating component 32. The rotating structure also includes a discharge groove 34, a guide plate 35, a pressure-resistant plate 36, a material placement plate 37, and an extension plate 38. The discharge groove 34 is located on one side of the base plate 20. The guide plate 35 is fixedly connected inside the discharge groove 34. The pressure-resistant plate 36 is fixedly connected to the outer side of the base plate 20 on the left side. The material placement plate 37 is fixedly connected to... The extension plate 38 is fixedly connected to the wall of the base plate 20 at the bottom of the unloading groove 34, and the base plate 20 is attached to the outside of the base plate 20 on the right side of the unloading groove 34. The unloading groove 34 is a rectangular inlet. The guide plate 35 is located on the side of the unloading groove 34, biased towards the material placement plate 37. The guide plate 35 is an arc-shaped plate, and the outer arc surface of the guide plate 35 faces the other side of the unloading groove 34. The unloading groove 34 can accommodate the lower mold 21 to pass through. The extension plate 38 is an L-shaped plate, and the top of the extension plate 38 can be aligned with the bottom of the unloading groove 34. The material placement plate 37 is a rectangular plate, and the pressure-resistant plate 36 is a semi-circular plate. The pressure-resistant plate 36, the material placement plate 37 and the top of the base plate 20 are flush. In practical use, the raw material for the nitrile rubber cold-resistant sealing ring to be vulcanized is first placed on the lower mold 21 located above the material placement plate 37. Then, the servo motor is turned on, and the servo motor drives the rotating block 30 to rotate. The rotating block 30 causes the lower mold 21 on its wall to rotate. As the rotating block 30 rotates, the lower mold 21 with the raw material is moved to directly below the upper mold. At this time, the upper mold is controlled to move downwards to cooperate with the raw material above the lower mold 21 for vulcanization. During this process, the next batch of raw material can be placed on the lower mold 21 that was previously located above the material placement plate 37. After the upper mold has completed vulcanization, the rotating block is controlled again. As the rotation continues, the sealing rings that have been prepared will move to the unloading groove 34 and flip downwards with the insertion post 33 as the center. At this time, the prepared sealing rings will automatically fall off from the wall of the lower mold 21 to the extension plate 38. Meanwhile, raw materials are placed in each lower mold 21 located above the material placement plate 37, and the lower mold 21 located above the pressure plate 36 will drive the raw materials to cooperate with the upper mold for vulcanization treatment. This process is repeated. When the lower mold 21 at the unloading groove 34 rotates with the rotating block 30, the inclined wall of the lower mold 21 will contact the outer arc surface of the guide plate 35 and be guided by the arc surface of the guide plate 35 to a flat position on the top of the substrate 20. In summary, by setting up a rotating structure and using the rotatable rotating block 30 to drive the lower mold 21, vulcanization, unloading, and raw material placement can be completed simultaneously. Compared with the traditional vulcanization preparation method, this scheme obviously has a more efficient preparation efficiency.

[0021] like Figure 4 and Figure 5As shown, the wall of the extension plate 38 is provided with a shaking structure, which includes an extension frame 40, a spring 41, a trigger head 42, and a limiting rod 43. The extension frame 40 is fixedly connected to the wall of the extension plate 38, the spring 41 is fixedly connected to the wall of the extension frame 40 facing the extension plate 38, the trigger head 42 is fixedly connected to the front wall of the spring 41, and the limiting rod 43 is fixedly connected to the wall of the trigger head 42. The extension frame 40 is a U-shaped plate with its opening facing the extension plate 38. A rectangular groove is provided on the wall of the extension plate 38 at the opening of the extension frame 40, and the spring 41 can pass through the rectangular groove on the wall of the extension plate 38. The trigger head 42 is located directly below the unloading groove 34 and is a semi-circular block. The limiting rod 43 is located on the wall of the trigger head 42 facing the extension plate 38 and can pass through the wall of the extension plate 38. In practical use, when the lower mold 21 flips downward from the unloading groove 34, the bottom of the unloading groove 34 will contact the arc surface of the trigger head 42. Then, the trigger head 42 will compress the spring 41 when it is subjected to impact force. The spring 41 will be released immediately after being compressed, thereby abutting the lower mold 21 above the extension plate 38 through the trigger head 42 to swing back and forth. The limit rod 43 will slide along the wall of the extension plate 38 as the trigger head 42 moves. In summary, by setting up a shaking structure, the lower mold 21 is oscillated by the contraction of the spring 41, thereby increasing the speed at which the prepared sealing ring is removed from the wall of the lower mold 21.

[0022] Working principle: First, the raw material for the nitrile rubber cold-resistant sealing ring to be vulcanized is placed on the lower mold 21 located above the material placement plate 37. Then, the servo motor is turned on, which drives the rotating block 30 to rotate. The rotating block 30 causes the lower mold 21 on its wall to rotate. As the rotating block 30 rotates, the lower mold 21 with the raw material is moved to directly below the upper mold. At this time, the upper mold is controlled to move downwards to cooperate with the raw material above the lower mold 21 for vulcanization. During this process, the next batch of raw material can be placed on the lower mold 21 that was previously located above the material placement plate 37. After the upper mold has completed vulcanization, the rotating block 30 is controlled again. As the rotation continues, the sealing rings that have been prepared will move to the unloading groove 34 and flip downwards with the insertion post 33 as the center. At this time, the prepared sealing rings will automatically fall off from the wall of the lower mold 21 to the extension plate 38. At the same time, raw materials will be placed in each lower mold 21 located above the material placement plate 37, and the lower mold 21 located above the pressure plate 36 will drive the raw materials to cooperate with the upper mold for vulcanization treatment. This process is repeated. When the lower mold 21 at the unloading groove 34 rotates with the rotating block 30, the inclined wall of the lower mold 21 will contact the outer arc surface of the guide plate 35 and be guided by the arc surface of the guide plate 35 to a flat position on the top of the substrate 20.
