[0022] During the actual application of this embodiment: the staff first needs to insert the rubber material 10 in a ring shape on the inner side of the lower mold 8, and then operate the controller 2 to control the extension of the hydraulic rod 5 as needed, so that the hydraulic rod 5 uses the telescopic end to push the hot pressing plate 6 downward along the guide rod 4, so that the hot pressing plate 6 drives the upper mold 9 to approach the lower mold 8 until the upper mold 9 and the lower mold 8 are closed. Then, the controller 2 is operated to control the hot pressing plate 6 and the hot pressing seat 7 to heat the upper mold 9 and the lower mold 8, and at the same time continue to control the hydraulic rod 5 to extend the preset length to apply pressure, so as to use pressure and heat and cooperate with the upper mold 9 and the lower mold 8 to shape, so that the rubber material 10 is hot-pressed into a sealing ring. When the hot pressing reaches the preset time, the hydraulic rod 5 can be controlled to contract, so that it drives the upper mold 9 and the lower mold 8 to separate from the mold through the hot pressing plate 6.

[0023] As a preferred embodiment of the present invention, the pushing member includes: The groove 12 is provided in the heat pressing seat 7 and is located outside the electric rod 11 and below the X-shaped groove 13; An X-shaped plate 14 is fixed above the telescopic end of the electric rod 11 and is located inside the X-shaped groove 13; The movable groove 20 is connected to the X-shaped groove 13; There are four support rings 15, which are movably arranged inside the four movable grooves 20 and are respectively fixed to the four ends of the X-shaped plate 14; There are four turntables 16 , each rotatably disposed in the support ring 15 via a bearing.

[0024] Specifically, the hot pressing seat 7 can provide stable support for the electric rod 11 and can provide space for the groove 12. The groove 12 can provide a penetrating moving channel for the telescopic end of the electric rod 11. The electric rod 11 can provide support for the X-shaped plate 14.

The support ring 15 can provide rotation support for the turntable 16 through the bearing.

[0025] The top supports include: The support rod 17 is symmetrically fixed on the turntable 16 and is located in the movable groove 20; The top ring 18 is fixed on the support rod 17 and passes through the lower mold 8; The top ring 18 fits the lower mold 8 and is flush with the inner bottom wall of the lower mold 8 to support the rubber material 10 .

[0026] Specifically, the turntable 16 can firmly support the support rod 17 and can drive the support rod 17 to rotate together under the action of external force. The support rod 17 can provide firm support for the top ring 18. The top ring 18 can provide support for the rubber material 10 and can cooperate with the lower mold 8 to provide positioning and molding space and support for the rubber material 10.

[0027] During actual application of this embodiment, after the rubber material 10 is hot-pressed into a sealing ring and the mold is opened, the controller 2 needs to control the electric rod 11 to extend, so that the electric rod 11 uses the telescopic end to push the X-shaped plate 14 to move upward along the X-shaped groove 13, so that the X-shaped plate 14 can use external force to drive the support ring 15 to move upward together, and the support ring 15 will drive the turntable 16 to move upward together in the movable groove 20 through the bearing. At the same time, the turntable 16 will use external force to drive the top ring 18 to move upward together through the support rod 17, and then the top ring 18 will use the upward external force to push the sealing ring formed in the lower mold 8 upward, so that the formed sealing ring can be pushed upward out of the lower mold 8 under the support of the top ring 18, thereby facilitating the ejection of the hot-pressed sealing ring from the lower mold 8 and improving the efficiency of removing the formed sealing ring.

[0028] As a preferred embodiment of the present invention, the scraping portion includes a guide member and an actuator. The guide member is provided through the support member. The actuator is elastically connected to the support member. The guide member includes: The rotary groove 30 has four portions, is provided in the hot pressing seat 7, and is respectively located below the four lower molds 8 and is communicated with the movable groove 20; The support 31 is fixed in the rotation groove 30; The screw rod 19 is fixed on the support 31 and passes through the turntable 16 to guide the turntable 16.

[0029] Specifically, the hot pressing seat 7 can provide a space for the rotary groove 30, the hot pressing seat 7 can firmly support the pillar 31, the pillar 31 can provide a firm support for the screw rod 19, the screw rod 19 can provide a rotation guide for the turntable 16, so that the turntable 16 can rotate along the screw rod 19 during the upward or downward movement under the action of external force, and the pillar 31 can provide rotation support for the tray 32 through the bearing, and the pillar 31 and the screw rod 19 can cooperate to provide a rotation space and a guide for the lifting and lowering movement for the end cover 35.

[0030] The executive components include: The through holes 21 are formed on both sides of the top ring 18 and are symmetrically distributed on the inner and outer sides of the top ring 18; The spring 22 is disposed in the through hole 21 and has one end fixedly connected to the top ring 18; A support plate 23 is fixed to the other end of the spring 22; One end of the silicone scraper 24 is fixed to the support plate 23 The guide parts are arranged through the hot pressing seat 7.

[0031] Specifically, the inner bottom wall edge of the lower mold 8 has a curvature, which can provide a moving guide for the silicone scraper 24, so that the silicone scraper 24 can be pushed and guided to move into the through hole 21 for reset during the downward movement of the silicone scraper 24. The top ring 18 can provide a space for the through hole 21, and the top ring 18 can firmly support the spring 22. The through hole 21 can provide a storage space for the spring 22, the support plate 23 and the silicone scraper 24. Figure 9 As shown, the lower mold 8 can provide resistance for the silicone scraper 24, so that the silicone scraper 24 can squeeze the spring 22 through the support plate 23, so that the spring 22 is squeezed and contracted to store energy under the support of the top ring 18.

[0032] The connecting parts include: There are four drain grooves 25, which are provided in the hot pressing seat 7 and communicate with the movable groove 20; The drawer 26 is inserted into the hot pressing seat 7 from the front and is located below the drain groove 25 .

[0033] Specifically, the hot pressing seat 7 can provide a space for the leakage groove 25 to be opened, and the movable groove 20 can provide a falling space for the residual rubber material 10 inside the lower mold 8, so that the residual rubber material 10 can fall into the leakage groove 25, and the leakage groove 25 can provide a channel for the residual rubber material 10 to fall into the drawer 26, so that the drawer 26 can store the residual rubber material 10.

[0034] When the top ring 18 moves upwards, it will rotate with the turntable 16. When the top ring 18 moves upwards, it will rotate with the turntable 16. When the top ring 18 moves upwards, it will rotate with the turntable 16. When the top ring 18 moves upwards, it will drive the silicone scraper 24 to move together. When the top ring 18 moves upwards to the inner side of the lower mold 8, the silicone scraper 24 will separate from the hot pressing seat 7, thereby eliminating the extrusion force it receives. At this time, the spring 22 will use the rebound force supported by the top ring 18 to push the silicone scraper 24 out of the through hole 21 to the outside through the support plate 23, so that the silicone scraper 24 contacts the inner wall of the lower mold 8. When the turntable 16 is pushed upwards and rotated by the electric rod 11, it will move through the support rod 17 and the top ring 18. The spring 22 is driven to rotate together, and the support plate 23 is driven to rotate together through the spring 22, so that the support plate 23 drives the silicone scraper 24 to rotate together, so that the silicone scraper 24 can scrape off the rubber material 10 remaining on the inner wall of the lower mold 8 during the rotation process, and the scraped rubber material 10 will fall along the inner wall of the lower mold 8 around the top ring 18 under the action of gravity to the inner side of the movable groove 20, and pass through the movable groove 20 to fall into the inner side of the leakage groove 25, and pass through the leakage groove 25 to fall into the drawer 26 for collection, and Before the next sealing ring molding operation is required, the electric rod 11 needs to be controlled to retract, so that the electric rod 11 pulls the top ring 18 downward through the X-shaped plate 14, the support ring 15, the turntable 16 and the support rod 17. At the same time, the turntable 16 also rotates along the spiral rod 19, and the top ring 18 drives the silicone scraper 24 to move downward and reset together through the spring 22 and the support plate 23. This allows the device to conveniently remove the rubber material 10 remaining on the inner wall of the lower mold 8 while ejecting the molded sealing ring. The staff can pull the drawer 26 toward the front according to the actual situation, so as to clean the collected residual rubber material 10; In summary, the top ring 18 will rotate during the process of ejecting the molded sealing ring, and can use friction to push the molded sealing ring to rotate together in the lower mold 8, thereby helping the sealing ring to separate from the inner wall of the lower mold 8 in the initial stage of ejecting the sealing ring.

The one-way valve 36 provided on the end cover 35 will pull the hose 29 to rotate together with the support 31 as the center of the circle, so that the hose 29 can pass through the perforation 37 and move into the rotation groove 30, thereby preventing the setting of the hose 29 from affecting As the turntable 16 rotates, the end cover 35 moves along the support 31 and the screw rod 19 during its upward movement, and the end cover 35 stretches the bellows 33 and the bellows 34 under the support of the tray 32 during its upward movement, so that the bellows 34 and the bellows 33 generate suction during the stretching process, and the release agent stored in the storage cylinder 27 is sucked out through the one-way valve 36 provided on the tray 32 and the hose 29 by the suction force, so that the release agent and air can pass through the hose 29 and the one-way valve 36 provided on the tray 32 and be sucked into the space between the bellows 34 and the bellows 33 for temporary storage. After the silicone scraper 24 moves upward to scrape off the remaining rubber material 10 and controls the electric rod 11 to retract, it will drive the turntable 16 to move downward together and rotate in conjunction with the spiral rod 19. During the downward movement and rotation process, the turntable 16 pushes the end cover 35 downward through the one-way valve 36 provided on the end cover 35, so that the end cover 35 can squeeze the bellows 33 and the bellows 34 to fold and contract to generate pressure under the support and cooperation of the tray 32, so that the release agent temporarily stored in the space between the bellows 33 and the bellows 34 can be squeezed into the suction pipe 43 under the action of pressure, so that the release agent can be The release agent is discharged into the conduit 38 through the suction pipe 43 and the one-way valve 36 provided on the end cover 35, and enters the through-channel 39 along the conduit 38. The release agent entering the through-channel 39 will enter the branch channel 40, pass through the branch channel 40 and enter the nozzle 41, and finally be atomized and sprayed out by the nozzle 41. The atomized release agent will pass through the bell mouth 42 and be sprayed onto the inner wall of the lower mold 8 as the turntable 16 descends and rotates, so as to be used for the next molding of the sealing ring, thereby facilitating the preparation of the release agent when ejecting the previously molded sealing ring, and automatically spraying the release agent onto the inner wall of the lower mold 8 after ejection.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
