Description

Technical Field

[0001] This utility model relates to the field of rubber bearing technology, specifically a rubber bearing vulcanization device. Background Technology

[0002] During the production of rubber bearings, a vulcanization process is required. Rubber bearings are made of alternating layers of rubber and steel plates, with a steel plate between adjacent layers of rubber.

[0003] The utility model CN222309508U discloses a rubber vibration isolation bearing vulcanization device, including a rubber vibration isolation bearing vulcanization base, the top of the rubber vibration isolation bearing vulcanization base is in contact with a vulcanization mechanism, the vulcanization mechanism includes a top mold, a heat insulation plate is fixed on the top of the top mold, and an opening is provided at the center of the top of the heat insulation plate.

[0004] The above technical solution, through the design of the vulcanization mechanism, adds a spring rod and a heat-conducting threaded ring. The spring rod can adapt to the demolding height of the rubber vibration isolation support, and the heat-conducting threaded ring can ensure that several steel plates of the rubber vibration isolation support are heated evenly during vulcanization, which improves the convenience of the device, the vulcanization rate, and the production quality of the rubber vibration isolation support. However, when vulcanization molding is carried out continuously, the separation between the rubber support and the mold plate is slow, making it inconvenient to quickly assemble and demold for the next set of vulcanization. At the same time, it cannot reduce the heat loss from the bottom and sides during vulcanization, resulting in uneven heat concentration during vulcanization. Utility Model Content

[0005] The purpose of this invention is to provide a rubber bearing vulcanization device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rubber bearing vulcanization device includes a support frame with a groove on its upper surface. A tray is placed in the groove, and an installation groove is formed on the upper surface of the tray. A vulcanization assembly for vulcanizing the rubber bearing is placed in the installation groove. A hydraulic cylinder is mounted on the top of the support frame. The telescopic arm of the hydraulic cylinder passes through the top of the support frame and extends above the vulcanization assembly. A pressure plate is provided at the end of the telescopic arm.

[0008] The vulcanizing assembly includes two symmetrical mold plates, each with a base at its bottom. One mold plate has a slot on its side wall and symmetrical latches at the ends of its outer walls on both sides. The other mold plate has a locking block corresponding to the slot and a hook corresponding to the latch on its outer wall. Heating coils are provided between the outer and inner walls of the mold plates, and heat insulation plates are provided outside the heating coils. A sealing cap is provided at the top between the two mold plates.

[0009] Furthermore, the hydraulic cylinder is fixedly connected to the top plate of the support frame by screws, and the telescopic arm slides with the top plate, while the top of the pressure plate and the bottom of the telescopic arm are fixedly connected by screws.

[0010] In this invention, the telescopic arm of the hydraulic cylinder extends or shortens to achieve a close contact between the bottom of the pressure plate and the top of the sealing cover. When the telescopic arm extends, the pressure plate presses the sealing cover tightly, which helps to press the internal rubber support firmly.

[0011] Specifically, the width of the inner wall of the chute is adapted to the width of the outer wall of the tray, a pull handle is provided at the right end of the tray, and the width of the inner wall of the mounting groove is adapted to the total width of the two bases spliced ​​together.

[0012] In this invention, the tray and the slide groove are slidably connected, and with the help of the pull handle, a force point is provided, which makes it easy to pull the tray out horizontally to remove and replace the vulcanizing components. With the help of the mounting groove, the splicing and installation of the two bases are restricted, which increases the stability of the installation.

[0013] It should be noted that the base and the mold plate are integrally formed, and the outer wall of the mold plate is provided with pull rings. The card block and the mold plate are integrally formed, and the width of the outer wall of the card block is adapted to the width of the inner wall of the card slot.

[0014] In this invention, the pull ring provides a point of force, making it easy to remove the mold plate from the mounting slot. The locking block and the locking slot are engaged to increase the tightness of the combination of the two mold plates and facilitate quick and easy corresponding insertion and installation.

[0015] Furthermore, the outer wall end of the mold plate is column-shaped, and the hook is welded to the corresponding column. The latch is fixed to the column on another mold plate by screws, and the latch is engaged with the corresponding hook in sequence.

[0016] In this utility model, both the lock and the hook are made of thickened steel. The lock and the hook are engaged to achieve a fixed overlapping fit between the two mold plates, allowing for quick assembly. The lock and the hook can be separated to facilitate the separation of the two mold plates and to quickly demold the internal rubber support.

[0017] It is worth noting that the heating coil is curved and fits against the side wall of the mold plate. One end of the connecting post on the heating coil extends out of the mold plate and is connected to the external connecting wire. The heat insulation plate has the same shape as the mold plate and is wrapped around the outside of the heating coil.

[0018] In this invention, after the two heating coils are connected to the external connecting wires, the power supply continuously generates heat and heats the inside of the mold plate. With the cooperation of the heat insulation plate, the heat generated by the heating coils is reduced from being lost from the outside of the mold plate, thus reducing the impact on the vulcanization and molding of the rubber support in the middle.

[0019] In addition, the width of the outer wall of the sealing cover is adapted to the total length of the width of the two bases spliced ​​together, and the bottom of the sealing cover is provided with a post, the outer diameter of which is adapted to the inner cavity diameter of the two mold plates combined.

[0020] In this invention, the sealing cap with the insert post is inserted into the top of the two mold plates, and the insert post extends between the two mold plates to fit tightly against and press firmly against the top of the rubber support.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. This utility model uses two mold plates with heating coils and heat insulation plates. The mold plates are connected by interlocking blocks and slots to form a barrel-shaped mold. The assembled structure is fixed by the interlocking and hooking. The interlocking and hooking can be separated by two pull rings to facilitate the separation and demolding of the two mold plates. A hydraulic cylinder with a pressure plate cooperates with the support frame. The pressure plate contacts the top of the sealing cover and presses the sealing cover to realize the compaction and vulcanization of the insert and the internal rubber support that needs to be vulcanized.

[0023] 2. This utility model features a tray with mounting grooves. The bases of the two mold plates are inserted into the mounting grooves. The tray is pulled horizontally with the help of a pull handle. The tray slides in the groove, which facilitates lifting the vulcanizing component and sliding it to the center position of the support frame. It corresponds to the hydraulic cylinder with a pressure plate. The pressure plate presses the vulcanizing component with a sealing cover, compacting and vulcanizing the rubber support. After completion, the tray can be removed by pulling the handle for demolding and separation. The heat insulation plate reduces heat loss and concentrates heat in the middle position.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figures 1-6 This embodiment provides a technical solution:

[0039] In this utility model, the tray 2 is slidably inserted into the slide groove 10, and with the cooperation of the pull handle 21, it provides a point of force, making it easy to pull the tray 2 out horizontally, so as to take out and replace the vulcanizing component 3. With the cooperation of the mounting groove 20, it restricts the splicing and installation of the two bases 300, increasing the stability of the installation.

[0040] Furthermore, the mounting groove 20 is provided with a vulcanizing component 3 for vulcanizing the rubber bearing, and a hydraulic cylinder 4 is provided on the top of the support frame 1. The telescopic arm of the hydraulic cylinder 4 passes through the top of the support frame 1 and extends above the vulcanizing component 3, and a pressure plate 40 is provided at the end of the telescopic arm. The hydraulic cylinder 4 is fixedly connected to the top plate of the support frame 1 by screws, and the telescopic arm slides with the top plate. The top of the pressure plate 40 is fixedly connected to the bottom of the telescopic arm by screws.

[0041] In this invention, the telescopic arm of the hydraulic cylinder 4 extends or shortens to achieve contact between the bottom of the pressure plate 40 and the top of the sealing cover 5. When the telescopic arm extends, the pressure plate 40 presses the sealing cover 5 tightly, which helps to press the internal rubber support firmly.

[0042] Specifically, the vulcanizing component 3 includes two symmetrical mold plates 30. Each mold plate 30 has a base 300 at its bottom. One mold plate 30 has a slot 301 on its side wall and latches 304 symmetrically provided at the ends of the outer walls on both sides. The other mold plate 30 has a latching block 302 corresponding to the slot 301. The base 300 and the mold plate 30 are integrally formed. Each mold plate 30 has a pull ring 305 on its outer wall. The latching block 302 and the mold plate 30 are integrally formed. The width of the outer wall of the latching block 302 is adapted to the width of the inner wall of the slot 301.

[0043] In this utility model, the pull ring 305 provides a point of force to facilitate the removal of the mold plate 30 from the mounting groove 20. The locking block 302 and the locking groove 301 are inserted and engaged to increase the tightness of the combination of the two mold plates 30 and facilitate quick and easy corresponding insertion and installation.

[0044] It should be noted that hooks 303 are provided on the outer wall of the mold plate 30 at the position corresponding to the latch 304. The end of the outer wall of the mold plate 30 is column-shaped, and the hooks 303 are welded to the corresponding columns. The latch 304 is fixedly connected to the column on another mold plate 30 by screws. The latch 304 is engaged with the corresponding hooks 303 in sequence.

[0045] In this utility model, both the latch 304 and the hook 303 are made of thickened steel. The latch 304 and the hook 303 are engaged to achieve a fixed overlapping fit between the two mold plates 30, enabling quick assembly. The latch 304 and the hook 303 can be separated to facilitate the separation of the two mold plates 30 and to quickly demold the internal rubber support.

[0046] Furthermore, heating rings 31 are provided in the area between the outer and inner walls of the mold plate 30, and heat insulation plates 32 are provided on the outer side of the heating rings 31. The heating rings 31 are curved and fit against the side wall of the mold plate 30. One end of the connecting post on the heating ring 31 extends out of the mold plate 30 and is connected to the external connecting wire. The heat insulation plate 32 has the same shape as the mold plate 30 and wraps around the outside of the heating rings 31.

[0047] In this invention, after the two heating coils 31 are connected to the external connecting wires, the power supply continues to generate heat and heats the inner side of the mold plate 30. With the cooperation of the heat insulation plate 32, the heat generated by the heating coils 31 is reduced from being lost from the outside of the mold plate 30, which would affect the vulcanization and molding of the rubber support in the middle.

[0048] Secondly, a sealing cap 5 is provided at the top position between the two mold plates 30.

[0049] It is worth adding that the width of the outer wall of the sealing cover 5 is matched with the total length of the width of the two bases 300 spliced ​​together, and the bottom of the sealing cover 5 is provided with a post 50, the outer diameter of which is matched with the inner cavity diameter of the two mold plates 30 combined.

[0050] In this utility model, the sealing cover 5 with the insert post 50 is inserted and engaged with the top of the two mold plates 30. The insert post 50 extends between the two mold plates 30, and fits tightly against and presses against the top of the rubber support.

[0051] In this embodiment, when the rubber bearing vulcanization device is in use, firstly, the hydraulic cylinder 4 with the pressure plate 40 is fixed to the top of the top plate on the support frame 1. Then, the heating ring 31 and the heat insulation plate 32 are sequentially combined and installed with the corresponding mold plate 30, and the mold plate 30 wraps around the heating ring 31 and the heat insulation plate 32. The two mold plates 30 are connected to the slot 301 through the locking block 302, and the two bases 300 are closely attached. Then, the latch 304 is connected to the corresponding hook 303 to realize the splicing of the two mold plates 30 into a barrel-shaped structure. Then, a layer of steel plate and a layer of rubber sheet are placed in the barrel-shaped structure. Then, the insertion post 50 on the sealing cover 5 is connected to the barrel-shaped compartment between the mold plate 30.

[0052] The vulcanizing assembly 3 is inserted into the mounting groove 20 via the base 300. With the help of the pull handle 21, the tray 2 is pushed from the front end of the slide 10 to the rear end. Then, the telescopic arm of the hydraulic cylinder 4 is extended, and the bottom of the pressure plate 40 is in close contact with the upper surface of the sealing cover 5 and pressed tightly. The bottom of the insertion post 50 is pressed into contact with the internal rubber sheet. Then, the connecting end post on the heating coil 31 is connected to the external connecting wire. The heating coil 31 continuously heats the inside of the two mold plates 30 to achieve vulcanization of the internal steel plate and rubber sheet. After a period of molding, demolding and separation are required. The telescopic arm of the hydraulic cylinder 4 is shortened. With the help of the pull handle 21, the tray 2 is taken out and the sealing cover 5 is taken out. Then, the corresponding latch 304 and hook 303 are separated. With the help of the pull ring 305, the two mold plates 30 are separated, and the internally vulcanized rubber support is separated and taken out for the next vulcanization.
