Description

Technical Field

[0001] This invention relates to the field of rubber vulcanizing machine technology, specifically to a rubber sealing ring vulcanizing machine. Background Technology

[0002] A rubber vulcanizing machine is an industrial device used to transform raw rubber into cured rubber products with elasticity, strength, and stability through heating and pressurization. This transformation process is called "vulcanization," and its core is to form a cross-linked structure between rubber molecular chains, thereby improving the physical and mechanical properties of the material. Vulcanizing machines are widely used in the production of various rubber and plastic products such as tires, rubber shoes, seals, conveyor belts, and medical rubber products.

[0003] Application CN120481151A discloses a vulcanizing machine for processing sealing rings in additive manufacturing. The machine controls the rotation of the support arm through the drive component, which drives the upper and lower templates to close, forming a vulcanizing tank to accommodate the initial blank of the 3D printed sealing ring. The air bladder of the pressurizing component expands after the air source is connected, sealing the gap and introducing high-temperature gas into the vulcanizing tank to achieve heating and pressurizing vulcanization of the sealing ring. The modular design eliminates the need for resealing or recalibration and is suitable for the efficient molding of sealing rings of various specifications.

[0004] Application CN108327152A discloses a vulcanizing machine for rubber sealing rings. The lower arm swings to drive the upper arm to swing, and the upper arm swings to drive the upper mold frame, upper template and driving component to flip. When the lower arm swings to abut against the swing arm, the upper template can flip to be directly above the lower template and the upper template is horizontal, which facilitates the downward translation of the upper template to close the mold. The swing arm restricts the swing amplitude of the lower arm when closing the mold, ensuring that the upper template can accurately flip to be horizontal and improve the mold closing accuracy.

[0005] However, the vulcanizing machine for rubber sealing rings disclosed above still has the following problems in actual use: the rubber sealing ring is vulcanized and heated between the upper and lower molds, but this type of vulcanization operation is directly formed in the vulcanization mold. When forming and unloading, the material needs to be unloaded inside the lower mold by means of scraping, etc. The vulcanizing machine has a compact layout space, which affects the unloading operation. At the same time, the scraping method is not only easy to damage the mold, but also more likely to cause rubber material residue.

[0006] Therefore, we propose a rubber sealing ring vulcanizing machine to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a rubber sealing ring vulcanizing machine to solve the problem that existing vulcanizing and heating methods for rubber sealing rings are carried out between the upper and lower molds. However, such vulcanization operations directly form the sealing rings in the vulcanizing mold. During the forming and unloading process, the material needs to be unloaded inside the lower mold by means of scraping or other methods. The vulcanizing machine has a compact layout, which affects the unloading operation. At the same time, the scraping method is not only easy to damage the mold, but also more likely to cause rubber material residue.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a rubber sealing ring vulcanizing machine, comprising a vulcanizing machine body and an electrical control box fixedly installed on the right side of the top surface of the vulcanizing machine body;

[0009] The vulcanizing machine body is provided with a vulcanizing mechanism on its top surface, and the vulcanizing mechanism includes a vulcanizing base, and a hydraulic cylinder is provided at the center of the vulcanizing base.

[0010] The vulcanizing base has a vulcanizing lower mold at the center of its top surface and an vulcanizing upper mold on its top surface. The vulcanizing lower mold rises and merges with the vulcanizing upper mold to achieve the heating and vulcanization of the rubber sealing ring.

[0011] A demolding mechanism is provided at the front of the vulcanizing machine body. The demolding mechanism includes a demolding slide plate, and demolding columns are fixedly installed at equal intervals on the bottom surface of the demolding slide plate to abut against the vulcanized rubber sealing ring to achieve material collection.

[0012] Preferably, the vulcanizing mechanism includes a vulcanizing column, and the bottom end of the vulcanizing column is fixedly installed at the four inner corners of the vulcanizing base at equal angles. The vulcanizing base is fixedly installed on the left side of the top surface of the vulcanizing machine body, and the top end of the vulcanizing column is fixedly connected to the four inner corners of the vulcanizing top cover. At the same time, the vulcanizing top cover and the vulcanizing base are vertically coaxial.

[0013] Preferably, the vulcanizing mechanism includes an upper vulcanizing mold fixedly installed in the middle of the bottom surface of the vulcanizing top cover, and the upper vulcanizing mold and the vulcanizing top cover are connected by a steam pipe, and the upper vulcanizing mold delivers steam to the interior of the combined lower vulcanizing mold to achieve rubber heating and molding.

[0014] Preferably, the vulcanizing mechanism includes a guide screw, which is rotatably mounted on the left and right sides of the top surface of the vulcanizing base via bearings. The rear ends of the guide screws are connected to each other via a pulley assembly. The external threads of the guide screws on the left and right sides are connected to vulcanizing slides. Vulcanizing pins are fixedly installed on the front and rear sides of the top of the vulcanizing slides.

[0015] Preferably, the vulcanization mechanism includes a vulcanization molding plate, and the vulcanization molding plate has vulcanization grooves evenly spaced inside. The vulcanization molding plate has vulcanization insertion holes symmetrically arranged at both ends. The vulcanization molding plate is fitted onto the outside of the vulcanization pin at the top of the vulcanization slide by the vulcanization insertion holes on both sides.

[0016] Preferably, the vulcanizing mechanism includes a vulcanizing forming plate located between the vulcanizing lower mold and the vulcanizing upper mold. The vulcanizing forming plate is slid to the top surface of the vulcanizing lower mold by the vulcanizing slide block. The vulcanizing lower mold, connected by a hydraulic cylinder, rises against the vulcanizing forming plate and, after merging with the vulcanizing upper mold, clamps the vulcanizing forming plate and the rubber strip on the top surface. During heating and vulcanization, the rubber strip is squeezed into the vulcanizing groove to form a rubber sealing ring.

[0017] Preferably, the demolding mechanism includes a demolding bracket, which is fixedly installed on the left and right sides of the front end of the vulcanizing base and the vulcanizing top cover. A lifting screw is rotatably installed at the front end of the demolding bracket via a bearing, and the lifting screw and the demolding bracket are connected to each other by a torsion spring.

[0018] Preferably, the demolding mechanism includes a demolding slide, which is slidably sleeved on the rear end of the demolding bracket, and the front end of the demolding slide is threaded onto the outer wall of the lifting screw. A transmission gear is fixedly installed at the lower end of the lifting screw, and the transmission gear meshes with the transmission rack, which is fixedly connected to the outer wall of the vulcanizing slides on the left and right sides.

[0019] Preferably, the demolding mechanism includes a positioning slide, and the rear end of the positioning slide is fixedly installed on the left and right sides of the front of the demolding slide. The demolding slide plate is slidably installed inside the positioning slide on the left and right sides. The front and rear ends of the demolding slide plate are connected to the positioning slide by a return spring. At the same time, the demolding slide plate and the vulcanizing plate are distributed in a longitudinal coaxial manner.

[0020] Preferably, the demolding mechanism includes a demolding slide that moves up and down along with the demolding carriage. When the demolding slide descends, it inserts the demolding column into the vulcanization groove inside the vulcanized molding plate. The demolding slide then slides forward with the vulcanized molding plate to increase the insertion depth, thereby collecting the rubber sealing ring formed inside the vulcanization groove by contact with the material.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: This rubber sealing ring vulcanizing machine uses a lower vulcanizing mold to drive the vulcanizing forming plate and the upper vulcanizing mold to merge, so that the rubber raw material can be vulcanized and cooled in the vulcanizing groove. When the demolding machine slides forward, it drives the descending demolding slide plate and demolding column to insert into the vulcanizing groove, thus pressing and squeezing the rubber sealing ring formed inside the vulcanizing groove downwards for demolding. The specific details are as follows:

[0022] 1. Insert the vulcanized molding plate into the vulcanized pin above the vulcanized slide through the vulcanized insertion holes on both sides. The guide screw above the vulcanized base rotates, causing the threaded vulcanized slide, the vulcanized molding plate above it, and the rubber strip material to move to the top of the vulcanized lower mold for corresponding arrangement.

[0023] Furthermore, the hydraulic cylinder inside the vulcanizing base drives the lower vulcanizing mold, which is fixedly connected above, to slide upward. The lower vulcanizing mold contacts and drives the vulcanizing forming plate to slide upward, so that the vulcanizing forming plate and the vulcanizing slide block are separated from each other. The lower vulcanizing mold drives the vulcanizing forming plate to adhere to the bottom surface of the upper vulcanizing mold, and then they merge together, thus preventing overflow during the vulcanizing operation.

[0024] 2. The electrical control box controls the heating steam to enter the space inside the vulcanizing upper mold through the through steam pipe, and heats the rubber strip to flow into the vulcanizing grooves opened inside the vulcanizing molding plate, so as to form a batch vulcanizing molding operation.

[0025] Furthermore, after the rubber strip is heated and cooled inside the vulcanized molding plate, the lower vulcanized mold vulcanized molding plate is driven down by the hydraulic cylinder, and then once again fitted onto the outside of the vulcanized pin above the vulcanized slide through the vulcanized insertion holes opened on the left and right sides, so that the vulcanized molding plate can be positioned again through the vulcanized slide, thereby driving the vulcanized slide and the vulcanized molding plate above to move forward.

[0026] 3. The vulcanizing slide moves the transmission rack forward, and the transmission gear meshing with it rotates with the lifting screw, so that the demolding slide moves the positioning slide and the demolding slide plate downward in sync, thereby corresponding with the vulcanizing molding plate that is sliding forward, and assisting in the subsequent demolding and unloading.

[0027] Furthermore, the demolding column at the bottom of the demolding slide plate is inserted into the vulcanization groove inside the vulcanized molding plate. As the vulcanized molding plate continues to slide forward, the demolding slide plate descends further. The vulcanized molding plate drives the inserted demolding slide plate to move inside the positioning slide, thereby ensuring that the demolding column is further inserted into the vulcanization groove, and the rubber sealing ring formed inside the vulcanization groove is pushed downward to demold.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figures 1-11 The present invention provides the following technical solution:

[0042] Example 1: To solve the problems of existing rubber sealing rings during vulcanization, this example discloses the following technical solution: a rubber sealing ring vulcanizing machine, including a vulcanizing machine body 1 and an electrical control box 2 fixedly installed on the right side of the top surface of the vulcanizing machine body 1; a vulcanizing mechanism is provided on the top surface of the vulcanizing machine body 1, and the vulcanizing mechanism includes a vulcanizing base 3 and a guide screw 12, and the guide screw 12 is rotatably installed on the left and right sides of the top surface of the vulcanizing base 3 through bearings, and the rear ends of the guide screw 12 are connected to each other through a pulley assembly 13, and the external threads of the guide screw 12 on the left and right sides are connected to vulcanizing slides 14, and vulcanizing pins 15 are fixedly installed on the front and rear sides of the top of the vulcanizing slides 14.

[0043] The vulcanizing mechanism includes a vulcanizing forming plate 16, and vulcanizing grooves 17 are equally spaced inside the vulcanizing forming plate 16. Vulcanizing insertion holes 18 are symmetrically arranged on the left and right sides of the vulcanizing forming plate 16. The vulcanizing forming plate 16 is fitted onto the outside of the vulcanizing pin 15 at the top of the vulcanizing slide block 14 by the vulcanizing insertion holes 18 on the left and right sides.

[0044] like Figures 5-7 As shown, when the rubber sealing ring needs to be vulcanized through the vulcanizing machine 1, the vulcanizing molding plate 16 is first installed above the vulcanizing slides 14 on the left and right sides through the vulcanizing insertion holes 18 opened at both ends. The vulcanizing pins 15 symmetrically distributed above the vulcanizing slides 14 are inserted through the vulcanizing insertion holes 18, thereby positioning and installing the vulcanizing molding plate 16 and the vulcanizing slides 14. Then, a rubber strip is placed above the vulcanizing groove 17 inside the vulcanizing molding plate 16, so that the sealing ring workpiece of the required specifications is formed inside the vulcanizing groove 17 during subsequent vulcanization heating.

[0045] Furthermore, the motor at the rear of the vulcanizing machine 1 operates, driving the guide screw 12 connected through the pulley assembly 13 to rotate, thereby sliding the vulcanizing slide blocks 14 threaded on the left and right sides and the vulcanizing molding plate 16 positioned above them backward, so that the vulcanizing slide blocks 14 can move the vulcanizing molding plate 16 and the rubber strip on the upper surface to the top of the vulcanizing lower mold 5 for subsequent vulcanizing operations.

[0046] Example 2: To solve the problems of existing rubber seals during vulcanization, this example discloses the following technical solution: A hydraulic cylinder 4 is provided at the internal center of the vulcanization base 3; a lower vulcanization mold 5 is provided at the center of the top surface of the vulcanization base 3, and an upper vulcanization mold 6 is provided on the top surface of the lower vulcanization mold 5; the lower vulcanization mold 5 rises and merges with the upper vulcanization mold 6 to achieve the heating and vulcanization of the rubber seal; the vulcanization mechanism includes a vulcanization column 9, and the bottom end of the vulcanization column 9 is fixedly installed at an equal angle on the vulcanization base. The vulcanizing base 3 is fixedly installed on the left side of the top surface of the vulcanizing machine body 1 at the four corners of the inside of the vulcanizing base 3, and the top of the vulcanizing column 9 is fixedly connected to the four corners of the inside of the vulcanizing top cover 10. At the same time, the vulcanizing top cover 10 and the vulcanizing base 3 are vertically coaxially distributed. The vulcanizing upper mold 6 included in the vulcanizing mechanism is fixedly installed in the middle of the bottom surface of the vulcanizing top cover 10, and the vulcanizing upper mold 6 and the vulcanizing top cover 10 are connected by a steam pipe 11. The vulcanizing upper mold 6 delivers steam to the inside of the combined vulcanizing lower mold 5 to achieve rubber heating and molding.

[0047] The vulcanizing mechanism includes a vulcanizing forming plate 16 located between the vulcanizing lower mold 5 and the vulcanizing upper mold 6. The vulcanizing forming plate 16 is slid to the top surface of the vulcanizing lower mold 5 by the vulcanizing slide block 14. The connected vulcanizing lower mold 5 is driven by the hydraulic cylinder 4 to rise against the vulcanizing forming plate 16. After merging with the vulcanizing upper mold 6, the vulcanizing forming plate 16 and the rubber strip on the top surface are clamped. During heating and vulcanization, the rubber strip is squeezed into the vulcanizing groove 17 to form a rubber sealing ring.

[0048] like Figures 1-3 As shown, when the vulcanizing molding plate 16 drives the rubber strip to slide above the vulcanizing lower mold 5 to achieve correspondence, the hydraulic cylinder 4 inside the vulcanizing base 3 drives the fixedly connected vulcanizing lower mold 5 to slide upward through the telescopic part at the upper end. The vulcanizing lower mold 5 abuts against the vulcanizing molding plate 16 on the top surface, causing it to separate from the vulcanizing slide 14. It continues to drive the vulcanizing molding plate 16 to move upward and merge with the vulcanizing upper mold 6. Then, the electric control box 2 controls the heating steam to enter the space inside the vulcanizing upper mold 6 through the through steam pipe 11, and heats the rubber strip to flow into the vulcanizing groove 17 opened inside the vulcanizing molding plate 16, so as to form a batch vulcanizing molding operation.

[0049] Furthermore, after the rubber strip is heated and cooled inside the vulcanized molding plate 16, the hydraulic cylinder 4 drives the vulcanizing lower mold 5 to move downwards. The vulcanized molding plate 16 on the top surface of the vulcanizing lower mold 5 follows and descends. It is then fitted onto the outside of the vulcanizing pin 15 above the vulcanizing slide 14 through the vulcanizing insertion holes 18 opened on the left and right sides, so that the vulcanized molding plate 16 can be positioned again by the vulcanizing slide 14. Then, the guide screw 12 above the vulcanizing base 3 rotates in the opposite direction, thereby driving the vulcanizing slide 14 and the vulcanized molding plate 16 above it to move forward, so as to carry out subsequent demolding and the previous loading operation.

[0050] Example 3: In order to solve the problems of existing rubber sealing rings during vulcanization, this example discloses the following technical solution: a demolding mechanism is provided at the front of the vulcanizing machine body 1. The demolding mechanism includes a demolding bracket 26, and the demolding bracket 26 is fixedly installed on the left and right sides of the front end of the vulcanizing base 3 and the vulcanizing top cover 10. The front end of the demolding bracket 26 is rotatably mounted with a lifting screw 19 through a bearing, and the lifting screw 19 and the demolding bracket 26 are connected to each other through a torsion spring 20.

[0051] The demolding mechanism includes a demolding slide 21, which is slidably sleeved on the rear end of the demolding bracket 26. The front end of the demolding slide 21 is threaded onto the outer wall of the lifting screw 19. A transmission gear 22 is fixedly installed at the lower end of the lifting screw 19. The transmission gear 22 meshes with the transmission rack 23, which is fixedly connected to the outer wall of the vulcanizing slides 14 on the left and right sides.

[0052] like Figures 8-9 As shown, the vulcanizing molding plate 16 above the vulcanizing machine body 1 is driven forward by the vulcanizing slide 14. When the vulcanizing slide 14 drives the outer transmission rack 23 to slide forward, it meshes with the transmission gear 22 below the lifting screw 19 and rotates. At the same time, the lifting screw 19 rotates synchronously. The demolding slide 21, which is threadedly connected to the lifting screw 19, is limited by the demolding bracket 26 so that the demolding slide 21 drives the positioning slide 24 and the demolding slide plate 7 to move downward synchronously, thereby corresponding with the vulcanizing molding plate 16 that is sliding forward, and assisting in the subsequent demolding and unloading.

[0053] Example 4: To solve the problems of existing rubber sealing rings during vulcanization, this example discloses the following technical solution: The demolding mechanism includes a demolding slide plate 7, and demolding columns 8 are fixedly installed at equal intervals on the bottom surface of the demolding slide plate 7 to abut against the vulcanized rubber sealing ring for material collection; The demolding mechanism includes a positioning slide 24, and the rear end of the positioning slide 24 is fixedly installed on the left and right sides of the front of the demolding slide 21, and the demolding slide plate 7 is slidably installed inside the positioning slides 24 on the left and right sides, and the front and rear ends of the demolding slide plate 7 are connected to the positioning slide 24 by a return spring 25, and the demolding slide plate 7 and the vulcanized plate 16 are distributed in a longitudinal coaxial manner.

[0054] The demolding mechanism includes a demolding slide plate 7 that moves up and down along with the demolding slide 21. When the demolding slide plate 7 descends, it inserts the demolding column 8 into the vulcanization groove 17 inside the vulcanization molding plate 16. The demolding slide plate 7 slides forward with the vulcanization molding plate 16 to increase the insertion depth, thereby collecting the rubber sealing ring formed inside the vulcanization groove 17 by contact with the material.

[0055] like Figure 4 , Figures 10-11 As shown, when the demolding slide 21 drives the positioning slide 24 and the demolding slide 7 to slide downwards, the demolding column 8 at the bottom of the demolding slide 7 is inserted into the vulcanization groove 17 inside the vulcanization molding plate 16. When the vulcanization molding plate 16 continues to slide forward, the demolding slide 7 descends further. The demolding slide 7, driven by the vulcanization molding plate 16, moves inside the positioning slide 24, thereby ensuring that the demolding slide 7 and the demolding column 8 at the bottom are further inserted into the vulcanization groove 17, and the rubber sealing ring formed inside the vulcanization groove 17 is pushed downwards to demold, thus facilitating collection and subsequent re-feeding vulcanization operations.

[0056] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
