Description

Technical Field

[0001] This utility model relates to the technical field of fluororubber sealing ring production, specifically a fluororubber sealing ring vulcanization mold based on quick mold change. Background Technology

[0002] Fluororubber, as a high-performance elastomer, is widely used in chemical, petroleum, and aerospace industries. To ensure the performance and service life of fluororubber products, vulcanization is an essential step. Vulcanization is a key step in the processing of fluororubber, its main purpose being to form a stable cross-linked structure between rubber molecular chains through a chemical reaction, thereby improving the rubber's strength, abrasion resistance, and chemical corrosion resistance. Unvulcanized fluororubber products are prone to deformation and aging during use, severely affecting their performance.

[0003] Because fluororubber releases hydrogen chloride and hydrogen fluoride during vulcanization, these chemicals corrode the mold, resulting in a shorter mold lifespan. Furthermore, different molds are required for different models and sizes of fluororubber seals during production. Existing fluororubber seal vulcanization molds are mostly fixed by bolts or clamps when changing, which increases the time required for each mold change and reduces the vulcanization efficiency of fluororubber seals. Utility Model Content

[0004] The purpose of this invention is to provide a vulcanizing mold for fluororubber sealing rings based on quick mold changing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0030] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0031] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0032] Please see Figures 1 to 8 In this embodiment of the utility model, a fluororubber sealing ring vulcanization mold based on quick mold changing includes a worktable 1, a guide rail 3, a first mold shell 7, a second mold shell 8, a rotating component, and a self-locking drive component.

[0033] For details, please refer to the following: Figure 1 , Figure 3 , Figure 4 and Figure 8 ,include;

[0034] A first mold shell 7 and a second mold shell 8 are disposed on the workbench 1, and the first mold shell 7 and the second mold shell 8 are adapted to each other.

[0035] The first mold shell 7 has a template 10 that can be detachably installed inside it, and a rotating part is provided on the side of the first mold shell 7.

[0036] A self-locking drive component is disposed on the side of the first mold shell 7 and connected to the rotating component to control the rotating component to rotate relative to the first mold shell 7 and lock the template 10.

[0037] In detail, in this embodiment, the fluororubber sealing ring vulcanizing mold based on quick mold changing described in this utility model is used. When making sealing rings of different sizes according to requirements, when the template 10 is replaced, the self-locking drive is manually pressed to release the locking work of the self-locking drive on the rotating part. When the self-locking drive is pressed to the end of its stroke, it rotates relative to the first mold shell 7 to drive the rotating part to rotate synchronously, so that the side end of the first mold shell 7 is open, so as to realize the quick disassembly and installation of the template 10 into the first mold shell 7. After the template 10 is installed, the self-locking drive is controlled to reset to restore the locking state of the rotating part, shortening the template 10 switching time while ensuring the stable connection between the template 10 and the first mold shell 7.

[0038] It should be noted that the second mold shell 8 is equipped with the same rotating parts and self-locking drive parts as the first mold shell 7. When the first mold shell 7 replaces the template 10, the second mold shell 8 is replaced accordingly.

[0039] For further solutions to this utility model, please refer to [link / reference]. Figure 4 The rotating component includes a rotating shaft 704 rotatably mounted on the side of the first mold shell 7. One end of the rotating shaft 704 forms a cylindrical cavity 707. At least one set of strip grooves 708 are formed on the inner wall of the cylindrical cavity 707, and a baffle 703 is fixedly connected to the rotating shaft 704.

[0040] Preferably, a through hole 705 is formed on the side end of the first mold shell 7, and at least one set of limiting grooves 706 are formed on the inner wall of the through hole 705.

[0041] The self-locking drive includes a drive rod 11, one end of which is slidably disposed in the through hole 705. A limiting block 1101 is provided on the drive rod 11 to slide and cooperate with the limiting groove 706, and a ball bearing 1102 adapted to the strip groove 708 is rolled on the drive rod 11.

[0042] It also includes a spring 12, which is disposed in the cylindrical cavity 707. One end of the spring 12 abuts against the inner end of the cylindrical cavity 707, and the other end abuts against the drive rod 11.

[0043] It should be noted that the limiting groove 706 is divided into a first vertical groove, a second arc-shaped groove, and a third vertical groove.

[0044] Preferably, at least one set of sliding grooves 702 are formed on the side wall of the first mold shell 7, and the template 10 is provided with a plug block 1001 that slides and engages with the sliding grooves 702.

[0045] In the initial state, when the baffle 703 abuts against the side end of the first mold shell 7, the limiting block 1101 is located in the third vertical groove. At this time, the spring 12 is in a compressed state. Under the action of the spring 12, the limiting block 1101 is squeezed into the third vertical groove, so that the position of the drive rod 11 is locked, so as to realize the locking work of the rotating shaft 704 and ensure the abutment of the baffle 703 against the first mold shell 7.

[0046] In detail, when the template 10 needs to be replaced, the drive rod 11 is manually controlled to slide relative to the through hole 705, so that the limiting block 1101 moves from the third vertical groove to the second arc groove. Then, the drive rod 11 is controlled to rotate, and under the constraint of the ball 1102 and the strip groove 708, the rotating shaft 704 is driven to rotate synchronously, so that the baffle 703 separates from the side end of the first mold shell 7. Then, the insertion block 1001 on the template 10 is aligned with the slide groove 702 and inserted into the first mold shell 7. After the template 10 is fully inserted into the first mold shell 7, the drive rod 11 is manually controlled to reset, so that the limiting block 1101 is once again stuck into the third vertical groove, so that the side end of the template 10 abuts against the baffle 703 and the side wall of the first mold shell 7 respectively, preventing the template 10 from shifting horizontally or vertically when the first mold shell 7 moves.

[0047] It should be noted that during the reset process of the drive rod 11, the drive rod 11 moves toward the rotating shaft 704. At this time, the limiting block 1101 moves into the first vertical groove, and the drive rod 11 squeezes the spring 12, causing the spring 12 to be compressed. When the limiting block 1101 moves into the second arc-shaped groove, the compression of the spring 12 is at its maximum value. When the drive rod 11 rotates relative to the through hole 705, the limiting block 1101 rotates in the second arc-shaped groove. When the baffle 703 rotates to abut against the side end of the first mold shell 7, it stops pressing the drive rod 11. At this time, under the action of the spring 12, the limiting block 1101 slides into the third vertical groove to lock the position of the drive rod 11, so as to realize the quick disassembly and installation of the template 10 and the first mold shell 7 while ensuring the stable connection between the template 10 and the first mold shell 7.

[0048] Preferably, the workbench 1 is provided with a guide rail 3, the guide rail 3 is slidably connected to the first mold shell 7, and the first mold shell 7 can move along the length direction of the guide rail 3.

[0049] The first mold shell 7 is provided with a slider 701, which is inserted into the guide rail 3 and slidably connected to the guide rail 3 to realize the directional sliding of the first mold shell 7.

[0050] Preferably, a support frame 2 is fixedly installed on the workbench 1, and a first electric telescopic rod 5 is fixedly connected to the support frame 2. The movable end of the first electric telescopic rod 5 is fixed to the bottom of the first mold shell 7.

[0051] Preferably, the workbench 1 is provided with a drive moving component for controlling the up and down movement of the second mold shell 8.

[0052] Preferably, the driving moving component includes a second electric telescopic rod 6 fixedly mounted on the workbench 1, the movable end of the second electric telescopic rod 6 is fixedly connected to a receiving plate 4, both ends of the receiving plate 4 are slidably connected to a guide rod 9 fixedly mounted on the workbench 1, and at least one placement groove is formed on the receiving plate 4.

[0053] Preferably, the second mold shell 8 is provided with a limiting rod 801 that is adapted to the placement groove.
