Description

Technical Field

[0001] The invention relates to the technical field of vulcanization molding, in particular to automatic vulcanization molding equipment for rubber sealing rings. Background Art

[0002] Vulcanizing equipment is a key component of the rubber vulcanization process. Its operating principle involves two main steps: heating and pressurization. First, the vulcanizing equipment is equipped with a heating system, typically using electricity or steam. This heating system heats the rubber material in the mold to the vulcanization temperature, typically between 150°C and 200°C, depending on the type of rubber material and the type of vulcanizing agent. Second, during the heating process, the vulcanizing equipment applies pressure through a hydraulic system to clamp the mold in the vulcanizing oven or vulcanizing chamber. This pressure ensures that the rubber material fully fills every detail of the mold at high temperatures and maintains the mold closed during the vulcanization process, preventing the rubber material from leaking out or deforming. When the mold is heated and pressurized, the vulcanizing agent in the rubber material reacts with the vulcanization-reactive groups, forming cross-links. These cross-links make the rubber material durable and impart its specific physical and chemical properties.

[0003] Before the staff controls the vulcanization molding equipment to carry out vulcanization molding, they need to place multiple rubber strips in sequence to the corresponding positions on the upper surface of the lower mold. Especially for the molding of some larger-sized sealing rings, the rubber strips need to be curled into a ring shape and placed in the mold cavity, and then the mold is closed and subsequent vulcanization molding is carried out. For mass production, the vulcanization molding equipment is in a stopped state during the placement of the rubber strips, which affects the vulcanization molding efficiency of the rubber sealing ring and affects production capacity.

[0004] In view of this, in order to overcome the above technical problems, the present invention proposes an automatic vulcanization molding device for rubber sealing rings, which solves the above technical problems. Summary of the Invention

[0005] In order to make up for the shortcomings of the existing technology, the present invention proposes an automatic vulcanization molding equipment for rubber sealing rings. The present invention rotates the first mold and the second mold around the rotating column, so that the first mold and the second mold can be cyclically replaced for vulcanization molding and loading and unloading. This greatly saves the vulcanization molding time of the sealing ring, and improves the vulcanization molding efficiency and production capacity of the sealing ring.

[0006] The technical solution adopted by the present invention to solve its technical problems is: the rubber sealing ring automatic vulcanization molding equipment described in the present invention includes a base and a control box on one side of the base; one corner of the upper surface of the base is vertically fixed to the support column; the upper end of the support column is fixed to the top seat; the lower surface of the top seat is fixed to the pressure plate through a hydraulic cylinder; the upper surface of the base and the lower surface of the top seat are rotatably connected to a rotating column; the rotating column is arranged away from the support column; the lower end of the rotating column is fixed to the motor output shaft; the motor drives the rotating column to rotate under the control of the control box; the outer wall of the rotating column is connected to the first mold and the second mold; the first mold and the second mold are symmetrically arranged about the center of the rotating column; the first mold and the second mold can be moved to directly below the pressure plate; the upper surfaces of the first mold and the second mold are provided with a cavity for molding.

[0008] Preferably, the rotating column rotates clockwise when viewed from above; a first magnet is provided in the first mold and the second mold at the upper position; an annular plate is provided under the first mold and the second mold; the annular plate is disconnected by a notch to form an arc; the notch is located directly below the rubber strip loading position; a second magnet is embedded in the annular plate; the second magnet is magnetically attracted to the first magnet; multiple first molds or second molds enter under the pressure plate during the stacking process.

[0009] Preferably, the annular plate is symmetrically divided into a loading section and a loading section; the second magnets are in multiple numbers and embedded in the upper surface of the annular plate; the setting density of the second magnets in the loading section of the annular plate increases as the distance from the notch increases; the magnetic force formed between the second magnets in the loading section of the annular plate and the first magnet increases as the distance from the notch increases.

[0010] Preferably, the arrangement density of the second magnets in the blanking section of the annular plate decreases as it approaches the notch; and the magnetic force formed between the second magnets and the first magnets in the blanking section of the annular plate decreases as it approaches the notch.

[0011] Preferably, the outer wall of the first spring is covered with a folding sleeve; the end of the folding sleeve is connected to the corresponding slide bar; the folding sleeve is located in the corresponding slide groove and can protect the first spring.

[0012] Preferably, the inner sides of the multiple folding sleeves in the same chute are connected through a first air hole; the inner sides of the folding sleeves in two chute are connected through a second air hole; and the folding sleeves are filled with a medium.

[0013] Preferably, the first air hole is provided on the sliding bar; an opening and closing groove is provided on the inner wall of the first air hole; one end of the opening and closing groove is close to the central axis of the rotating column, and the other end is away from the central axis of the rotating column; an opening and closing block is slidably connected in the opening and closing groove; the opening and closing block is connected to the wall of the opening and closing groove by an elastic rope between the end close to the central axis of the rotating column and the wall of the opening and closing groove; the rotating column will drive the opening and closing block to be staggered with the first air hole during the rotation process, and when the rotating column is stopped, the elastic rope pulls the opening and closing block to block the first air hole.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The present invention rotates the first mold and the second mold around the rotating column, so that the first mold and the second mold can be cyclically replaced for vulcanization molding and loading and unloading, which greatly saves the vulcanization molding time of the sealing ring and improves the vulcanization molding efficiency and production capacity of the sealing ring.

[0016] 2. In the present invention, before the first mold reaches the pressure plate as the rotating column rotates, multiple first molds contact each other and clamp the corresponding rubber strips. When the rubber strips on the first molds are clamped, the rotating column can drive the multiple stacked first molds to move quickly to directly under the pressure plate. On the one hand, this ensures the efficiency of the first molds entering under the pressure plate, and on the other hand, it prevents the rubber strips from shifting during the movement of the first mold, thereby ensuring the vulcanization molding quality of the sealing ring.

[0017] 3. In the present invention, when the multiple first molds are separated from each other before reaching the notch, the sealing ring in the cavity of the first mold will be exposed to the air in advance, thereby further reducing the temperature of the sealing ring in the cavity and further enhancing the product performance of the sealing ring. In addition, since the process of the multiple first molds moving away from each other is a gradual process, the rapid separation of the multiple first molds can avoid the tearing of the sealing ring and the surrounding residual material, which facilitates the subsequent demolding of the residual material and the formed sealing ring as a whole.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figures 1 to 5 As shown, the present invention includes the following embodiments:

[0027] Example 1:

[0028] A rubber sealing ring automatic vulcanization molding equipment includes a base 1 and a control box 11 on one side of the base 1; one corner of the upper surface of the base 1 is vertically fixed to a support column 12; the upper end of the support column 12 is fixed to a top seat 13; the lower surface of the top seat 13 is fixed to a pressure plate 15 through a hydraulic cylinder 14; a rotating column 2 is rotatably connected between the upper surface of the base 1 and the lower surface of the top seat 13; the rotating column 2 is arranged away from the support column 12; the lower end of the rotating column 2 is fixed to the output shaft of a motor 21; the motor 21 drives the rotating column 2 to rotate under the control of the control box 11; the outer wall of the rotating column 2 is connected to a first mold 3 and a second mold 4; the first mold 3 and the second mold 4 are arranged symmetrically about the center of the rotating column 2; the first mold 3 and the second mold 4 can be moved to directly below the pressure plate 15; the upper surfaces of the first mold 3 and the second mold 4 are provided with a cavity for molding.

[0029] During operation, before the staff uses the vulcanization molding equipment to mold the sealing ring, they need to control the motor 21 to rotate through the control box 11. The rotating motor 21 will drive the rotating column 2 to rotate, and the rotating rotating column 2 will drive the first mold 3 and the second mold 4 to rotate; the first mold 3 moves out from between the top seat 13 and the base 1 after rotation, and the second mold 4 moves in between the top seat 13 and the base 1 after rotation, and is located directly below the pressing plate 15. Then, while keeping the first mold 3 and the second mold 4 stationary, the staff places multiple rubber strips toward the corresponding positions of the cavity on the upper surface of the first mold 3. After the placement of the rubber strips is completed, The control box 11 is started to drive the motor 21 to rotate again, and the motor 21 will drive the rotating column 2 to rotate. During the rotation of the rotating column 2, the first mold 3 and the second mold 4 will be driven to move. The first mold 3 will rotate between the top seat 13 and the base 1 during the rotation around the rotating column 2, and the first mold 3 will move to just below the pressure plate 15, while the second mold 4 will move out from between the top seat 13 and the base 1 to the outside during the rotation around the rotating column 2. Then the control box 11 controls the motor 21 to stop moving again, and the controller will control the hydraulic cylinder 14 to extend and drive the pressure plate 15 to move downward. During the downward movement of the pressure plate 15, it will press on the upper surface of the first mold 3, so that the cavity can be sealed. Then, the rubber strip in the cavity is heated and pressure is applied at the same time, so that the vulcanizing agent in the rubber strip reacts with the vulcanization active group to form a cross-linked structure, and finally cooled and solidified to complete the vulcanization molding process of the rubber strip in the first mold 3. During the vulcanization molding of the sealing ring in the first mold 3, the second mold 4 is in a state of moving out of the top seat 13 and the base 1. In this way, the staff places the rubber strip in the second mold 4 during the vulcanization molding of the sealing ring in the first mold 3, which greatly saves the vulcanization molding time. Before the first mold 3 completes the vulcanization molding of the sealing ring, the second mold 4 has completed the placement of the rubber strip. As the first mold 3 is vulcanized, the second mold 4 is in a state of moving out of the top seat 13 and the base 1. The sealing ring is formed, the pressing plate 15 moves upward under the action of the hydraulic cylinder 14, and the motor 21 drives the rotating column 2 to rotate 180 degrees again, so that the positions of the first mold 3 and the second mold 4 are exchanged, and the staff removes the sealing ring formed on the first mold 3 and replaces the rubber strip after cleaning, while the rubber strip on the second mold 4 is vulcanized after the pressing plate 15 moves downward. This is repeated to achieve non-stop and continuous vulcanization molding of the sealing ring. In addition, the first mold 3 and the second mold 4 replace their respective positions under the rotation of the motor 21, so that the staff only needs to operate at one position, which also indirectly reduces the labor intensity of the staff;

[0030] The present invention rotates the first mold 3 and the second mold 4 around the rotating column 2, so that the first mold 3 and the second mold 4 can be cyclically replaced for vulcanization molding and loading and unloading, which greatly saves the vulcanization molding time of the sealing ring and improves the vulcanization molding efficiency and production capacity of the sealing ring.

[0031] Example 2:

[0032] Two slide grooves 22 are provided on the outer wall of the rotating column 2 along the vertical direction; the two slide grooves 22 are symmetrically arranged about the center of the rotating column 2, and the first mold 3 and the second mold 4 correspond to the corresponding slide grooves 22; the number of the first mold 3 and the second mold 4 is multiple; the first mold 3 and the second mold 4 are slidably connected in the corresponding slide groove 22 through the slide bar 5; the slide bar 5 in the lower position is fixedly connected to the corresponding slide groove 22; the multiple slide bars 5 in the slide groove 22 are connected by the first spring 51.

[0033] In this embodiment, the rotating column 2 rotates clockwise when viewed from above; a first magnet 31 is provided in the first mold 3 and the second mold 4 at the upper position; an annular plate 6 is provided below the first mold 3 and the second mold 4; the annular plate 6 is interrupted by a notch 61 to form an arc; the notch 61 is located directly below the rubber strip loading position; a second magnet 62 is embedded in the annular plate 6; the second magnet 62 is magnetically attracted to the first magnet 31; multiple first molds 3 or second molds 4 enter under the pressure plate 15 during the stacking process.

[0034] In this embodiment, the annular plate 6 is symmetrically divided into an upper material section 63 and a lower material section 64; the number of the second magnets 62 is multiple and embedded in the upper surface of the annular plate 6; the arrangement density of the second magnets 62 in the upper material section 63 of the annular plate 6 increases as the distance from the notch 61 increases; the magnetic force formed between the second magnets 62 in the upper material section 63 of the annular plate 6 and the first magnet 31 increases as the distance from the notch 61 increases.

[0035] In this embodiment, the density of the second magnets 62 in the blanking section 64 of the annular plate 6 decreases as it approaches the notch 61 ; the magnetic force formed between the second magnets 62 and the first magnets 31 in the blanking section 64 of the annular plate 6 decreases as it approaches the notch 61 .

[0036] During operation, taking the process in which the sealing ring on the second mold 4 is vulcanized and molded just below the pressure plate 15, and the process in which the first mold 3 is placed at the outer loading position between the base 1 and the top seat 13 for example, when multiple first molds 3 are located just above the notch 61, the first magnet 31 embedded in the topmost first mold 3 is staggered with the annular plate 6 in the horizontal direction, so that the multiple first molds 3 are separated from each other by the elastic force of their respective first springs 51 to form a gap, and the elastic force of the multiple first springs 51 increases from top to bottom, so that the multiple first molds 3 are under the elastic force of the first springs 51. In a state of being away from each other, multiple first molds 3 can facilitate the placement of rubber strips when they are away from each other. Compared with a single first mold 3, multiple first molds 3 distributed up and down can further improve the output and efficiency of sealing ring production. The rubber strip will fall into the upper surface cavity position of the first mold 3 under the placement of the staff, and no rubber strip is placed on the upper surface of the first mold 3 with the first magnet 31 at the top. Similarly, no rubber strip is placed on the upper surface of the second mold 4 with the first magnet 31 at the top. As the rubber strip on the first mold 3 is placed, the sealing ring on the second mold 4 is also vulcanized. After the first die 3 is formed, the motor 21 drives the rotating column 2 to rotate clockwise, and the rotating column 2 drives the first die 3 to move clockwise from above the notch 61 to the position of the feeding section 63 of the annular plate 6. Since the density of the second magnet 62 embedded in the feeding section 63 of the annular plate 6 increases as it moves away from the notch 61, as the rotating column 2 rotates, the magnetic force between the second magnet 62 of the feeding section 63 of the annular plate 6 and the first magnet 31 in the first die 3 gradually increases, so that the top first die 3 drives the slide bar 5 to move down gradually along the corresponding slide groove 22 to overcome the corresponding first spring 51. The downward movement of multiple first die 3 is a gradual process. The rotating column 2 is used to rotate the first mold 3 and the rotating column 2 is used to rotate the first mold 3. ...After the multiple stacked first molds 3 move to just below the pressing plate 15, the pressing plate 15 is driven downward by the hydraulic cylinder 14, so that the multiple stacked first molds 3 are further compressed, and the lower surface of the adjacent upper first mold 3 is adapted to the cavity of the upper surface of the lower first mold 3, so that the rubber strips in the upper surface cavity of the multiple first molds 3 are vulcanized to form a sealing ring. After the vulcanization molding of the sealing ring on the upper surface of the first mold 3 is completed, the pressing plate 15 moves upward, and the rotating column 2 rotates clockwise again to drive the first mold 3 into the blanking section 64 of the annular plate 6. Since the density of the second magnet 62 embedded in the blanking section 64 of the annular plate 6 decreases as it approaches the notch 61, the magnetic force formed between the second magnet 62 embedded in the blanking section 64 of the annular plate 6 and the first magnet 31 in the first mold 3 decreases as it approaches the notch 61. The molds 3 move away from each other under the elastic force of the multiple first springs 51, causing the multiple contacting first molds 3 to separate from each other as the rotating cylinder 2 rotates. When the multiple first molds 3 separate from each other before reaching the notch 61, the sealing ring in the cavity of the first mold 3 is exposed to the air in advance, thereby further reducing the temperature of the sealing ring in the cavity and further enhancing the product performance of the sealing ring. In addition, because the multiple first molds 3 move away from each other in a gradual process, the rapid separation of the multiple first molds 3 prevents the sealing ring from tearing off from the surrounding residual material, facilitating the subsequent removal of the residual material and the formed sealing ring as a whole. After the multiple first molds 3 move to directly above the notch 61, the staff begins to remove the residual material and the formed sealing ring from the cavity, and after cleaning, re-insert the rubber strip, and repeat this process.

[0037] Example 3:

[0038] The outer wall of the first spring 51 is covered with a folding sleeve 52 ; the end of the folding sleeve 52 is connected to the corresponding slide bar 5 ; the folding sleeve 52 is located in the corresponding slide groove 22 and can protect the first spring 51 .

[0039] In this embodiment, the inner sides of multiple folding sleeves 52 in the same chute 22 are connected through the first air hole 53; the inner sides of the folding sleeves 52 in two chute 22 are connected through the second air hole 54; and the folding sleeves 52 are filled with a medium.

[0040] During operation, after the rubber strip on the first mold 3 is placed, the first mold 3 moves toward the loading section 63 of the annular plate 6 under the rotation of the rotating column 2. In the process of increasing the magnetic force between the first magnet 31 and the second magnet 62, the first mold 3 will make multiple first molds 3 close to each other and stack, so that multiple slides 5 will move downward with the movement of the first mold 3. The folding sleeves 52 between adjacent slides 5 are squeezed in the process of the slides 5 approaching each other. The medium in the squeezed folding sleeves 52 will be connected to each other along the first air holes 53 and enter into another folding sleeve 52 along the second air holes 54. , thereby assisting another folding sleeve 52 to unfold. The other folding sleeve 52 corresponds to the second mold 4. When the second mold 4 moves out from under the pressure plate 15, it will enter the blanking section 64 of the annular plate 6. When the second mold 4 moves toward the notch 61, the magnetic force of the second mold 4 will gradually decrease, so that the multiple second molds 4 move away from each other to form a gap. When the multiple second molds 4 move upward and away from each other, they will drive the corresponding slide bar 5 to slide in the slide groove 22, and under the dual action of the unfolded folding sleeve 52, the multiple second molds 4 can move upward and unfold each other. In this way, when one of the folding sleeves 52 is pressed In this case, the other folding sleeve 52 must be unfolded, so that the first mold 3 and the second mold 4 can be unfolded or folded at their respective positions, making the vulcanization molding process of the sealing ring smoother and more stable; after the first mold 3 is stacked and enters just below the pressure plate 15, the multiple second molds 4 move away from each other and move to just above the notch 61, and then the removal of the remaining material and the molding sealing ring begins. Due to the protection of the folding sleeve 52 on the first spring 51, it is difficult for debris to enter the chute 22 to jam the first spring 51, making the first spring 51 work more stably. In addition, when the remaining material and molding on the second mold 4 are being processed, the second mold 4 is pressed against the first spring 51. During the removal of the sealing ring and the subsequent placement of the rubber strips, the multiple first molds 3 are pressed tightly after the pressure plate 15 moves down, making it impossible for the multiple first molds 3 to move away from each other, and the folding sleeves 52 corresponding to the first molds 3 cannot be unfolded, so that the medium in the folding sleeves 52 corresponding to the second mold 4 cannot enter the folding sleeves 52 corresponding to the first mold 3, thereby making it impossible for the multiple second molds 4 to be folded, thereby improving the stability of the second mold 4, and allowing the staff to stably unload, clean and load the second mold 4, so that the vulcanization molding stability of the sealing ring is further improved.

[0041] Example 4:

[0042] The first air hole 53 is set on the sliding bar 5; the inner wall of the first air hole 53 is provided with an opening and closing groove 55; one end of the opening and closing groove 55 is close to the central axis of the rotating column 2, and the other end is away from the central axis of the rotating column 2; an opening and closing block 56 is slidably connected in the opening and closing groove 55; the opening and closing block 56 is connected to the groove wall of the opening and closing groove 55 by an elastic rope 57 between the end of the opening and closing block 56 close to the central axis of the rotating column 2; the rotating column 2 will drive the opening and closing block 56 to stagger with the first air hole 53 during the rotation process, and when the rotating column 2 is stopped, the elastic rope 57 pulls the opening and closing block 56 to block the first air hole 53.

[0043] During operation, taking the process of the first mold 3 completing the placement of the rubber strip and moving toward the feeding section 63 of the annular plate 6 as an example, the opening and closing block 56 is subjected to centrifugal force and pulls the elastic rope 57 under the rotation of the rotating column 2, and the opening and closing block 56 moves in the opening and closing groove 55 to open the first air hole 53, so that the interiors of multiple folding sleeves 52 in the same slide groove 22 are connected. In this way, when multiple first molds 3 are stacked close to each other, the media in the multiple folding sleeves 52 will flow to each other and enter another folding sleeve 52 along the second air hole 54, and the first mold 3 moves to the bottom of the pressure plate 15. At the same time, when the second mold 4 moves to just above the notch 61, the folding sleeves 52 in the two chutes 22 complete the transfer of the internal medium. Since the first mold 3 is stacked and pressed by the pressure plate 15, the folding sleeves 52 in the two chutes 22 cannot flow again. When the rotating column 2 stops rotating, the elastic rope 57 will pull the opening and closing block 56 to move in the opening and closing groove 55 and block the corresponding first air hole 53, so that the first air holes 53 between the multiple expanded folding sleeves 52 are disconnected, so that the multiple second molds 4 are more stable during the unloading and loading process and are not easy to shake.
