DETAILED DESCRIPTION

[0031] The following is combined with Figure 1 -Attached Figure 3 , further details of this application are given. Example

[0032] Seal ring vulcanization molding pusher device, refer to Figure 1 and Figure 2The base frame 1 serves as the supporting foundation of the entire device, and its upper end carries the molding mechanism 2. The core components of the molding mechanism 2 include a lower mold 29 and an upper mold 25. The upper mold 25 is connected to the movable plate 22 through the rotating rods 27 on both sides. The movable plate 22 is closely matched with the rotating rod 27 through the rotating groove 21, thereby realizing the flexible lifting and lowering of the upper mold 25. At the same time, a plurality of screws 23 are also slidably provided on the movable plate 22. The movable rod 20 connected to the lower end of the screw 23 further enhances the lifting stability. In addition, the pushing and stamping equipment 4 is located on one side of the base frame 1, and the rotating wheel 26 thereon cooperates with the upper mold 25 to assist the upper mold 25 in performing the discharging operation after vulcanization is completed. The pushing rod of the pushing and stamping equipment 4 is also fixed to one side of the lower mold 29.

[0033] Reference Figure 2 The engaging groove 201 on the lower mold 29 cooperates with the engaging block 24 at the lower end of the upper mold 25, further enhancing the stability and sealing of the mold when it is closed. The rectangular array distribution of the screws 23 enables the movable plate 22 to be more evenly and stably stressed when adjusting the height. The rectangular array distribution of the nuts 28 not only strengthens the connection strength between the screws 23 and the movable plate 22, but also makes the adjustment process smoother and more reliable.

[0034] Reference Figure 3 The lifting mechanism 3 is installed on both sides of the base frame 1 and is used in conjunction with the molding mechanism 2. The lifting mechanism 3 is mainly composed of a lifting frame 32, a motor 31, a threaded rod 34, a lifting plate 33, a lifting rod 37 and a lifting platform 38. The motor 31 is installed at the upper end of the lifting frame 32, and its output end is connected to the threaded rod 34. The lifting plate 33 is driven up and down on the threaded rod 34 through the principle of thread transmission. Lifting rods 37 are fixed on both sides of the lifting plate 33. These lifting rods 37 play a guiding and stabilizing role in the lifting process. At the same time, a lifting platform 38 is also fixed on one side of the lifting plate 33. The lifting platform 38 is connected to the moving rod 20 in the molding mechanism 2, thereby realizing the smooth lifting and precise positioning of the upper mold 25.

[0035] Reference Figure 3 The support frame 30 set at the lower end of the motor 31 not only provides a stable support for the motor 31, but also enhances the rigidity and stability of the entire lifting mechanism 3 through its fixed connection with the upper end of the lifting frame 32. The lifting groove 35 enables the lifting plate 33 to effectively reduce the friction resistance and energy loss during the lifting process when it moves. The sliding matching mechanism of the lifting slot 36 makes the lifting action smoother and more stable, reducing mechanical wear and failure rate.

[0036] The implementation principle of the embodiment of the present application is as follows: through the forming mechanism 2, the lifting mechanism 3 is started to drive the moving rod 20 to move up and down. The moving rod 20 can drive the moving plate 22 to move through the screw 23. The screw 23 can fine-tune and fix the moving plate 22 through the nut 28. When the moving plate 22 moves upward, one side of the upper mold 25 will contact the rotating wheel 26, so that the upper mold 25 is tilted, and one of the rotating rods 27 on both sides is disengaged from the rotating groove 21, so that the lower end of the upper mold 25 can be exposed, which is convenient for collecting the sealing ring. When moving downward, as it is disengaged from the rotating wheel 26, the rotating rod 27 can re-enter the rotating groove 21 for limiting. During the movement, the locking block 24 will fit into the locking groove 201, and cooperate with the pushing and stamping equipment 4 to move and stamp the upper mold 25 and the lower mold 29.

[0037] The locking groove 201 on the lower mold 29 cooperates with the locking block 24 at the lower end of the upper mold 25, further enhancing the stability and sealing of the mold when it is closed. The rectangular array distribution of the screw 23 enables the movable plate 22 to be more evenly and stably stressed when adjusting the height. The rectangular array distribution of the nut 28 not only strengthens the connection strength between the screw 23 and the movable plate 22, but also makes the adjustment process smoother and more reliable.

[0038] By using the lifting mechanism 3, the motor 31 at the upper end of the lifting frame 32 is started, so that the motor 31 can drive the threaded rod 34 to rotate through the output end, so that the threaded rod 34 can drive the lifting plate 33 to slide in the lifting slot 36. At the same time, the lifting plate 33 can be guided and limited by the lifting rods 37 on both sides, so that the lifting plate 33 can drive the moving rod 20 to move up and down through the lifting platform 38.

[0039] The support frame 30 set at the lower end of the motor 31 not only provides a stable support for the motor 31, but also enhances the rigidity and stability of the entire lifting mechanism 3 through its fixed connection with the upper end of the lifting frame 32. The lifting groove 35 enables the lifting plate 33 to effectively reduce the friction resistance and energy loss during the lifting process when it moves. The sliding matching mechanism of the lifting slot 36 makes the lifting action smoother and more stable, reducing mechanical wear and failure rate.
