Description

Technical Field

[0001] This invention relates to the field of hot pressing molding technology for sealing rings, and more specifically to a hot pressing molding equipment for sealing rings. Background Technology

[0002] Sealing rings are an important basic sealing element, and their production mainly adopts the thermoforming process. That is, using thermoforming equipment, pre-made rubber material is heated and pressurized in a mold to vulcanize and form the ring. Existing thermoforming equipment usually includes an upper mold, a lower mold, a thermoforming seat and platen to provide heat, and a hydraulic rod to provide pressure. After a production cycle is completed, that is, after the sealing ring is formed, the mold needs to be opened and the formed sealing ring needs to be removed from the lower mold. However, existing thermoforming equipment still has technical problems that urgently need to be solved.

[0003] After molding, the sealing ring needs to be removed manually or by a simple ejector mechanism, which is inefficient and may cause product deformation or damage due to uneven force during removal. Secondly, during the hot pressing process, a small amount of adhesive will inevitably adhere to the inner wall of the mold. These residues will affect the molding quality and surface finish of the next product, so the mold must be cleaned before the next batch of material is fed.

[0004] Therefore, there is an urgent need for a sealing ring hot pressing molding equipment that can effectively solve the problems of low automation and low efficiency in finished product removal and mold cleaning of existing sealing ring hot pressing molding equipment. Summary of the Invention

[0005] This invention provides a hot-press molding equipment for sealing rings. During the process of using an electric rod to push the top ring to eject the molded sealing ring, the inclined cylinder, in conjunction with the guide of the spiral rod, causes the top ring and the silicone scraper mounted on it to rotate synchronously. This achieves the simultaneous completion of ejecting the sealing ring and scraping and cleaning the residual adhesive material on the inner wall of the lower mold, improving the degree of automation, shortening the non-working time of the equipment in a production cycle, and improving production efficiency.

This allows the thermoforming equipment to eject the product and simultaneously scrape and clean the residual adhesive material on the inner wall of the lower mold. In this way, the two independent steps of product ejection and mold cleaning are combined into one, achieving automated operation without manual intervention. This shortens the non-working time of the equipment in a production cycle and improves production efficiency. Attached Figure Description

[0073] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0074] like Figures 1 to 11 As shown, an embodiment of the present invention provides a sealing ring hot pressing forming device, including a hot press base 1 and a hot press seat 7 fixed on the hot press base 1. A hot press plate 6 is flexibly arranged above the hot press seat 7. Four lower molds 8 are symmetrically fixed at the upper end of the hot press seat 7, and four upper molds 9 are symmetrically fixed at the lower end of the hot press plate 6, with the upper molds 9 corresponding to the lower molds 8. The device also includes:

[0075] The top is pushed up and the lifting mechanism is set inside the hot press base 7 and moves through the lower mold 8. It includes an electric rod 11 embedded and fixed at the center of the hot press base 7, and a support and push member fixed at the telescopic end of the electric rod 11. It also includes four movable slots 20 and one X-shaped slot 13 opened on the hot press base 7. The support and push member is movably set in the movable slot 20 and located in the X-shaped slot 13. It also includes a support and push member fixed on the support and push member. The support and push member moves through the movable slot 20 and the lower mold 8 to support and push out the sealing ring formed in the lower mold 8.

[0076] The scraping part is provided in the lower mold 8 and the hot press seat 7 and is connected to the push top to cooperate with the push top to remove the adhesive material 10 adhering to the lower mold 8. It includes a spiral rod 19 that passes through the push support and a silicone scraper 24 that is elastically connected to the push support and symmetrically arranged.

[0077] The spraying section is movably disposed within the hot press base 7 and extends through the push top. It includes a support storage component inserted into the hot press base 7 from the front, and a suction spray component disposed through the support push component and the support top component. The suction spray component is movably disposed within the hot press base 7 and communicates with the support storage component, so as to spray the release agent into the mold 8 downward after the sealing ring is ejected and during the reset push top process.

[0078] Specifically, a controller 2 is fixed on one side of the hot press base 1, a protective frame 3 is fixed on the top of the hot press base 1, and the protective frame 3 is located outside the hot press base 7 and the hot press plate 6. Guide rods 4 are symmetrically fixed on the hot press base 1, and the guide rods 4 are fixedly connected to the inner top wall of the protective frame 3. A hydraulic rod 5 is fixed on the protective frame 3, and the telescopic end of the hydraulic rod 5 is set through the upper end of the protective frame 3. The telescopic end of the hydraulic rod 5 is fixedly connected to the hot press plate 6, and the hot press plate 6 is guided and connected to the guide rod 4.

[0079] Guide rod 4 can provide lifting and guiding function for hot press plate 6 under the support of hot press base 1. Hydraulic rod 5 can push hot press plate 6 up and down with telescopic end under the support of guard frame 3. Hot press plate 6 and hot press base 7 can provide support for upper mold 9 and lower mold 8 respectively. Hot press plate 6 and hot press base 7 can heat upper mold 9 and lower mold 8, so that upper mold 9 and lower mold 8 can close and cooperate to hot press rubber material 10 into sealing ring.

[0080] In practical application of this embodiment: First, the operator needs to insert the rubber material 10 in a ring shape inside the lower mold 8. Then, as needed, the operator controls the controller 2 to extend the hydraulic rod 5, so that the hydraulic rod 5 pushes the hot press plate 6 downward along the guide rod 4 using its telescopic end. The hot press plate 6 then moves the upper mold 9 closer to the lower mold 8 until the upper mold 9 and the lower mold 8 are closed. After that, the operator controls the controller 2 to heat the upper mold 9 and the lower mold 8 using the hot press plate 6 and the hot press seat 7. At the same time, the operator continues to control the hydraulic rod 5 to extend to a preset length to apply pressure. Thus, the pressure and heat, combined with the upper mold 9 and the lower mold 8, are used to shape the rubber material 10 into a sealing ring. When the hot pressing reaches the preset time, the operator controls the hydraulic rod 5 to retract, so that it drives the upper mold 9 and the lower mold 8 to separate from the mold through the hot press plate 6.

[0081] In a preferred embodiment of the present invention, the support member includes:

[0082] The groove 12 is formed inside the hot press seat 7 and is located outside the electric rod 11 and below the X-shaped groove 13;

[0083] X-shaped plate 14 is fixed above the telescopic end of electric rod 11 and located inside X-shaped groove 13;

[0084] The movable slot 20 and the X-shaped slot 13 are connected;

[0085] The support ring 15 has four rings, which are movably disposed inside the four movable slots 20 and are respectively fixed to the four ends of the X-shaped plate 14.

[0086] There are four turntables 16, which are rotatably mounted in the support ring 15 via bearings.

[0087] Specifically, the hot press base 7 provides stable support for the electric rod 11 and provides space for the groove 12. The groove 12 provides a through-movement channel for the telescopic end of the electric rod 11, and the electric rod 11 provides support for the X-shaped plate 14. The X-shaped groove 13 provides space for the X-shaped plate 14 to move, while the movable groove 20 provides lifting and rotation space for the support ring 15 and the support plate. The support ring 15 provides rotational support for the turntable 16 through the bearing.

[0088] The support components include:

[0089] The support rod 17 is symmetrically fixed on the turntable 16 and located within the movable groove 20;

[0090] The top ring 18 is fixed to the support rod 17 and passes through the lower mold 8;

[0091] The top ring 18 fits against the lower mold 8 and is flush with the inner bottom wall of the lower mold 8 to support the rubber material 10.

[0092] Specifically, the turntable 16 can stably 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 stable 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 space and support for the positioning and molding of the rubber material 10.

[0093] In practical application, after the rubber compound 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. The electric rod 11 uses its telescopic end to push the X-shaped plate 14 upward along the X-shaped groove 13. The X-shaped plate 14 can use external force to drive the support ring 15 to move upward together. 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. Then, the top ring 18 uses the upward external force to push the sealing ring formed in the lower mold 8 upward. The formed sealing ring can be pushed upward by the top ring 18 to the lower mold 8, 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.

[0094] In a preferred embodiment of the present invention, the scraping part includes a guide member and an actuator. The guide member passes through the support member, and the actuator is elastically connected to the support member. The guide member includes:

[0095] The rotary groove 30 has four openings, which are opened in the hot press base 7 and are respectively located below the four lower molds 8, and are connected to the movable groove 20;

[0096] The support column 31 is fixed inside the swivel groove 30;

[0097] The spiral rod 19 is fixed on the support column 31 and passes through the turntable 16, and is guided by the turntable 16.

[0098] Specifically, the hot press base 7 provides space for the swivel groove 30, the hot press base 7 can stably support the support column 31, the support column 31 can provide stable support for the screw rod 19, the screw rod 19 can provide rotational guidance for the turntable 16, so that the turntable 16 can rotate along the screw rod 19 during upward or downward movement under the action of external force, and the support column 31 can provide rotational support for the tray 32 through the bearing, and the support column 31 and the screw rod 19 can cooperate to provide rotational space and lifting and lowering guidance for the end cover 35.

[0099] The executable includes:

[0100] Through holes 21 are provided on both sides of the top ring 18 and are symmetrically distributed on the inner and outer sides of the top ring 18.

[0101] Spring 22 is disposed in through hole 21, and one end is fixedly connected to top ring 18;

[0102] Support plate 23 is fixed to the other end of spring 22;

[0103] One end of the silicone scraper 24 is fixedly connected to the support plate 23.

[0104] The guide component is installed through the heat press base 7.

[0105] Specifically, the inner bottom wall edge of the lower mold 8 has a curvature, which provides a moving guide for the silicone scraper 24, so that the silicone scraper 24 can be pushed and guided into the through hole 21 to reset during the downward movement of the silicone scraper 24. The top ring 18 can provide opening space for the through hole 21, and the top ring 18 can stably support the spring 22. The through hole 21 can provide 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 a blocking effect for the silicone scraper 24, so that the silicone scraper 24 can squeeze the spring 22 through the support plate 23, and the spring 22 can be squeezed and contracted to store energy under the support of the top ring 18.

[0106] The conductive components include:

[0107] The trough 25 has four sections, which are opened in the hot press base 7 and communicate with the movable groove 20;

[0108] Drawer 26 is inserted into the hot press base 7 from the front and is located below the slot 25.

[0109] Specifically, the hot press base 7 can provide opening space for the slot 25, the movable slot 20 can provide downward space for the residual adhesive 10 inside the lower mold 8, so that the residual adhesive 10 can fall into the slot 25, and the slot 25 can provide a channel for the residual adhesive 10 to fall into the drawer 26, so that the drawer 26 can store the residual adhesive 10.

[0110] In practical application, when the electric rod 11 extends and pushes the turntable 16 upward through the X-shaped plate 14 and the support ring 15, the turntable 16 rotates around the bearing on its outer side under the action of the rotating groove 30 and external force, and supported by the support ring 15. Simultaneously, the turntable 16 drives the support rod 17 to rotate, and the support rod 17 drives the top ring 18 to rotate along with the turntable 16 as it moves upward. During the upward movement of the top ring 18, the silicone scraper 24 moves along with it. When the top ring 18 moves upward to the inner side of the lower mold 8, the silicone scraper 24 separates from the hot press seat 7, thus eliminating the pressure it experiences. At this time, the spring 22, supported by the top ring 18, uses its rebound force to push the silicone scraper 24 out of the through hole 21 through the support plate 23, allowing the silicone scraper 24 to contact the inner wall of the lower mold 8. During the upward movement and rotation of the turntable 16 by the electric rod 11, the support rod 17 and the top ring 18... The spring 22 rotates together with the support plate 23, which in turn rotates the silicone scraper 24. During rotation, the silicone scraper 24 scrapes off the residual adhesive 10 from the inner wall of the lower mold 8. The scraped adhesive 10, under gravity, flows along the inner wall of the lower mold 8, around the top ring 18, and falls into the inner side of the movable groove 20. It then passes through the movable groove 20 and into the inner side of the drain trough 25, finally falling into the drawer 26 for collection. Before the next sealing ring molding operation, 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 will also rotate along the spiral rod 19, and the top ring 18 will drive the silicone scraper 24 to move downward and reset through the spring 22 and the support plate 23. This allows the device to easily remove the adhesive material 10 remaining on the inner wall of the lower mold 8 while ejecting the molded sealing ring.

[0111] Staff can pull the drawer 26 forward as needed to clean up the collected residual adhesive 10.

[0112] In summary, the top ring 18 rotates during the ejection of the formed sealing ring, and can use friction to push the formed 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 ejection.

[0113] In a preferred embodiment of the present invention, the support includes:

[0114] Storage cylinder 27, with a through-hole connection to the front of drawer 26;

[0115] Inlet 28 is opened above the storage cylinder 27;

[0116] The flexible hose 29 has one end extending through one side of the storage tank 27, and the other end extending movably through the hot press seat 7 into the vortex 30.

[0117] Specifically, drawer 26 provides support for storage cylinder 27, storage cylinder 27 provides storage space for release agent, and sprue 28 provides a channel for the release agent to be injected into storage cylinder 27.

[0118] The suction nozzle includes:

[0119] The tray 32 is rotatably mounted on the outside of the support column 31 via a bearing and is located within the swivel groove 30;

[0120] Corrugated pipe 33 is fixed to the upper end of tray 32;

[0121] The corrugated cylinder 34 is sleeved on the outside of the support column 31, and its lower end is fixedly connected to the inner bottom wall of the tray 32.

[0122] End cap 35 is movably sleeved on the outside of support column 31 and fixedly connected to the upper end of corrugated cylinder 34 and corrugated pipe 33.

[0123] Suction and discharge components are provided through the tray 32 and the end cap 35;

[0124] The painted parts are set through the top ring 18 and the strut 17.

[0125] Specifically, the support column 31 can provide rotational support for the tray 32 and the end cap 35 through the bearing. The tray 32 can provide support for the bellows 33 and the bellows 34. The space between the bellows 33 and the bellows 34 can provide temporary storage space for the release agent. The end cap 35 cooperates with the tray 32 to seal the space between the bellows 33 and the bellows 34. The bellows 34 and the bellows 33 are made of rubber and can be stretched and extended under external force and can be folded and shortened under external force.

[0126] The suction and discharge components include:

[0127] One-way valve 36 is provided through tray 32 and end cap 35, with two through-through valves on each end cap 35 and one through-through valve on one side of each tray 32;

[0128] The input end of the one-way valve 36 located on one side of the tray 32 is connected to the other end of the hose 29;

[0129] The conduit 38 is symmetrically fixed inside the turntable 16, and one end of it passes through the bottom of the turntable 16 and is connected to the output end of the one-way valve 36 provided on the end cover 35. The two one-way valves 36 provided on the end cover 35 are fixedly connected to the turntable 16.

[0130] A straw 43 is fixed to the lower end of a one-way valve 36 provided on the end cap 35, and the straw 43 extends into the tray 32.

[0131] Specifically, the end cap 35 and the tray 32 provide stable support for the one-way valve 36. The one-way valve 36 is a valve type. The one-way valve 36 on the tray 32 can only provide a channel for the release agent to enter the tray 32, while the one-way valve 36 on the end cap 35 can only provide a channel for the release agent to be discharged from the suction tube 43. The turntable 16 provides stable support for the conduit 38. The conduit 38 can provide a flow channel for the release agent discharged from the one-way valve 36 on the end cap 35. The release agent can enter the passage 39.

[0132] Painted parts include:

[0133] Passage 39, through support pole 17 is opened;

[0134] The branch channel 40 is symmetrically opened inside the top ring 18 and located below the through hole 21, with its lower end extending through the bottom of the top ring 18;

[0135] The upper end of the passage 39 is connected to the lower end of the branch passage 40, and the lower end of the passage 39 is connected to the upper end of the conduit 38.

[0136] The upper end of the splitter 40 has two output terminals, which face the outer and inner sides of the top ring 18 respectively;

[0137] The nozzle 41 is symmetrically fixed inside the top ring 18 and located below the through hole 21, and is connected to the output end of the channel 40;

[0138] Each top ring 18 has four nozzles 41 symmetrically arranged inside;

[0139] The nozzles 42 are four in number, symmetrically arranged on the inner and outer sides of the top ring 18, and located on the outer side of the nozzle 41.

[0140] Specifically, the hot press base 7 has a through hole 37, which is connected to the swivel groove 30 and the drawer 26. The support rod 17 can provide space for the through channel 39. The through channel 39 can provide a channel for the release agent in the conduit 38 to enter the branch channel 40. The branch channel 40 can provide a channel for the release agent to enter the nozzle 41. The nozzle 41 can atomize and spray the release agent under pressure. The flared mouth 42 can provide a discharge channel for the release agent. The flared mouth 42 can also prevent the scraped residual adhesive 10 from being trapped by its own inclination. The through hole 37 can provide a through channel for the hose 29 to move through.

[0141] In practical application, when using the hot press molding equipment for the first time, it is necessary to manually spray the release agent onto the inner wall of the lower mold 8 once.

[0142] Before using the device, the staff needs to pull the drawer 26 forward so that the drawer 26 moves the storage cylinder 27 forward together to expose the injection port 28. Then, the release agent is injected into the storage cylinder 27 from the injection port for storage.

[0143] When the electric rod 11 extends, causing the turntable 16 to move upward, the turntable 16 will pull the end cover 35 upward and rotate synchronously through the one-way valve 36 on the end cover 35 (the support column 31 and the screw rod 19 are on the same center). At the same time, the end cover 35 will rotate together with the one-way valve 36 on the end cover 35 through the bellows 33, the bellows cylinder 34 and the end cover 35. The one-way valve 36 on the end cover 35 will then pull the hose 29 to rotate around the support column 31, allowing the hose 29 to pass through the perforation 37 and move into the swivel groove 30, thereby preventing the installation of the hose 29 from affecting the rotation. As the turntable 16 rotates, the end cap 35 moves upward along the support column 31 and the screw rod 19. During this upward movement, the end cap 35, supported by the tray 32, stretches the bellows 33 and the bellows cylinder 34, causing them to generate suction. This suction draws out the mold release agent stored in the reservoir 27 through the one-way valve 36 on the tray 32 and the hose 29. The mold release agent and air are then drawn into the space between the bellows cylinder 34 and the bellows 33 for temporary storage, passing through the hose 29 and the one-way valve 36 on the tray 32. When the silicone scraper 24 moves upward to scrape off the residual adhesive 10 and controls the electric rod 11 to retract, it will drive the turntable 16 to move downward together and rotate in cooperation with the screw rod 19. During the downward movement and rotation of the turntable 16, the one-way valve 36 on the end cap 35 pushes the end cap 35 downward. Under the support of the tray 32, the end cap 35 can squeeze the corrugated tube 33 and the corrugated cylinder 34 to fold and shrink, generating pressure. This allows the release agent temporarily stored in the space between the corrugated tube 33 and the corrugated cylinder 34 to be squeezed into the suction tube 43 under pressure, so that the release agent can be released. The release agent is discharged through the one-way valve 36 provided on the suction tube 43 and the end cap 35 into the conduit 38, and enters the channel 39 along the conduit 38. The release agent entering the channel 39 will enter the branch channel 40, and enter the nozzle 41 through the branch channel 40. Finally, it will be atomized and sprayed out by the nozzle 41. The atomized release agent will pass through the flare 42 and be sprayed onto the inner wall of the lower mold 8 as the turntable 16 descends and rotates, for use in the next molding of the sealing ring. This makes it convenient to prepare the release agent when ejecting the previous molding of the sealing ring, and automatically spray the release agent onto the inner wall of the lower mold 8 after ejection.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
