Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of vulcanization equipment, and in particular, to a lightweight insulator forming and processing equipment. Background Art

[0002] Insulators, as crucial insulating components in power systems, play a crucial role in supporting and insulating electrical equipment. With the development of the power industry, higher requirements have been placed on the performance and weight of insulators. Lightweight insulators, due to their light weight and ease of installation and transportation, have been widely used in power projects. Lightweight insulators are typically manufactured by combining a core rod and a rubber strip, followed by vulcanization molding. Currently, in the process of vulcanizing and molding a core rod and a silicone rubber strip, existing lightweight insulator molding equipment often requires manual assistance for the placement of the core rod and rubber strip, as well as the removal of the insulator after molding, due to the low degree of automation of the equipment. Specifically, a rubber strip must first be placed on the lower mold, followed by the core rod, and then a rubber strip covered on the core rod before vulcanization can begin. This entire process is not only time-consuming, but if operated continuously, the residual heat of the vulcanizer will cause the rubber strip first placed on the lower mold to soften and shrink slightly. In addition, the mandrel squeezes the rubber strip, causing the rubber strip on the lower mold to deform prematurely. This results in inconsistent shrinkage of the two rubber strips arranged on the upper and lower sides of the core rod, resulting in incomplete and damaged edges of the insulator after vulcanization. The existing solution is to use a larger rubber strip to compensate for the shrinkage of the rubber strip. Although this can effectively solve the above problem, it results in a significant waste of rubber strips and makes demolding and subsequent processing difficult.

[0003] Therefore, there is an urgent need for a lightweight insulator forming and processing equipment that can solve the above problems and achieve efficient and precise production. Summary of the Invention

[0004] To overcome the above defects, the present invention provides a lightweight insulator molding and processing equipment, which solves the technical problems in the prior art of directly feeding the material into the vulcanizer mold, which leads to incorrect rubber strip position and easy shrinkage of the vulcanizer due to heat.

The placement frame can also drive the formed lightweight insulator to move away from the mold to separate from the mold.

[0006] Optionally, the mold includes a fixed upper mold and a lifting lower mold, both the fixed upper mold and the lifting lower mold have a mold cavity for molding lightweight insulators, and the placement frame can move up and down synchronously with the lifting lower mold.

[0007] Optionally, the material rack includes: A rotating shaft rotatably connected to the outer wall of the lifting lower mold; There are two side beams, which are respectively connected to the two ends of the rotating shaft and can swing vertically around the rotating shaft; the side beams are provided with a slide arranged along the length direction and horizontally passing through, and a slider is slidably arranged in the slide, and the placement frame is fixedly connected to the slider.

The side beam rod can be swung vertically upward around the rotating shaft so that the side beam rod is engaged with the fixed rod through the opening. When the opening is engaged with the fixed rod, the side beam rod can move up with the lifting lower mold, and the fixed rod can slide with the slide to push the slider and the placement frame downward with the help of the fixed rod.

[0009] Optionally, a guide rod is further provided on the side of the side beam rod away from the placement frame, and a plurality of rings are slidably provided on the guide rod, the rings correspond to the slider one by one and are fixedly connected, and a spring is provided between adjacent rings, and the spring is used to push the ring toward the side close to the opening.

[0010] Optionally, a sleeve is provided on the outer periphery of the guide rod, and an accommodating space for accommodating the compressed spring is formed between the sleeve and the guide rod. When the opening is engaged with the fixing rod, the two adjacent sliders can compress the spring under the action of the fixing rod until the two sliders fit together, so that the multiple placement frames are stacked close to each other.

[0011] Optionally, the multiple placement frames are: A first placement frame is connected to the side beam and is used to place the core rod; There are two second placement frames, which are symmetrically arranged on the upper and lower sides of the first placement frame. The second placement frames are used to place the rubber strip.

[0012] Optionally, the first placement frame has a slot for supporting the core rod, and the slot is clamped with the core rod; the second placement frame is hingedly provided with a clamping plate at the corners, and the clamping plate is used to limit and fix the corners of the rubber strip.

The arc-shaped protrusion slides in cooperation with the spiral guide groove, and the telescopic push rod can move upward and extend into the through hole, so as to drive the card plate to swing laterally to disengage from the rubber strip with the help of the cooperation between the arc-shaped protrusion and the spiral guide groove.

[0014] Optionally, a diagonal support rod is provided on the feeding side of the vulcanizer, and the diagonal support rod is used to support the material rack in a horizontal state.

[0015] The beneficial effects of the embodiments of the present invention are: In the present invention, before starting production, the operator first places the core rod and rubber strip in a placement frame and fixes them in position in the placement frame. This can avoid wrinkles caused by directly placing the rubber strip on the mold. The size of the placement frame can also be used as a measure of the amount of rubber strip used, avoiding waste of rubber strip. Subsequently, the material rack begins to swing vertically with the hinge as the axis. As the material rack swings, the placement frame gradually moves toward the vulcanizer. When it reaches the specified position, the placement frame is located between the two molds. Next, the upper and lower molds of the vulcanizer are closed, and the material in the mold is vulcanized.

The equipment realizes automated operations from material transportation to finished product removal. Compared with traditional equipment that requires a lot of manual assistance in placing and removing materials, production efficiency is improved. At the same time, since the material can be stably fixed in the placement frame, problems such as deformation and inconsistent shrinkage of the rubber strip caused by improper manual operation or residual heat of the vulcanizer are avoided, thereby effectively ensuring the molding quality of the insulator and reducing the defective rate.

Therefore, it should not be understood as a limitation on the present invention.

[0023] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0024] like Figures 1 to 7As shown, it shows a lightweight insulator molding and processing equipment in one embodiment of the present invention, which is used to combine a core rod and a rubber strip and then vulcanize and mold them to form a lightweight insulator, including a vulcanizer 1, which is equipped with a mold 2; a material rack 3 is vertically swingingly set on the outer wall of the vulcanizer 1; a placement frame 4 is slidably set on the material rack 3 along the length direction of the material rack 3, and the placement frame 4 is used to place the core rod and rubber strip to be vulcanized, as well as the molded lightweight insulator; wherein, the material rack 3 can drive the placement frame 4 to swing in the direction close to the vulcanizer 1, so that the placement frame 4 drives the core rod and rubber strip to be vulcanized to move to the mold 2, and the placement frame 4 can drive the molded lightweight insulator to separate from the mold 2.

[0025] For example, Figure 1 and Figure 2 As shown, the main body of the vulcanizer 1 is made of a solid steel structure, with two upper and lower molds inside. A heater is installed inside the mold 2, which can evenly transfer heat and provide a stable temperature environment for the vulcanization of the insulator. The mold 2 is firmly mounted on the heating plate by bolts and will not move during the vulcanization process. The material rack 3 is in the shape of a rectangular frame as a whole. The bottom of the material rack 3 is connected to the outer wall of the vulcanizer 1 by a hinge, which allows the material rack 3 to swing vertically to the vertical direction with the hinge as the axis. It should be noted that the swing angle of the material rack 3 is 90°. The placement frame 4 is also a rectangular frame structure, but the area of the placement frame 4 is larger than that of the mold 2.

[0026] Before starting production, the operator first places the core rod and the rubber strip in the placement frame 4 respectively, and fixes them in position in the placement frame 4. This can avoid wrinkles caused by placing the rubber strip directly on the mold 2, and the size of the placement frame 4 can also be used as a measure of the amount of rubber strip used to avoid waste of rubber strips. Subsequently, the material rack 3 begins to swing vertically with the hinge as the axis. As the material rack 3 swings, the placement frame 4 gradually moves toward the direction of the vulcanizer 1. When it reaches the specified position, the placement frame 4 is located between the two molds 2. Then, the upper and lower molds 2 of the vulcanizer 1 are closed, and the material in the mold 2 is vulcanized. After vulcanization is completed, the upper and lower molds are opened, and the material rack 3 swings in the opposite direction, driving the placement frame 4 to separate the molded lightweight insulator from the mold 2, completing a complete production process.

[0027] This equipment automates all operations, from material delivery to finished product removal. Compared to traditional equipment that requires extensive manual labor for material placement and removal, it improves production efficiency. Furthermore, because the material is stably secured within the placement frame 4, problems such as rubber strip deformation and inconsistent shrinkage caused by improper manual operation or residual heat from the vulcanizer 1 are avoided, effectively ensuring the molding quality of the insulator and reducing the defective rate.

[0028] In some examples, the mold 2 consists of two parts: a fixed upper mold 202 and a lifting lower mold 201. The fixed upper mold 202 is rectangular as a whole. The mold cavity 2011 at the bottom of the fixed upper mold 202 is precisely machined according to the shape of the lightweight insulator. The inner wall of the mold cavity 2011 is finely polished, and the surface is smooth and has good wear resistance, which can ensure that the surface of the insulator after molding is flat and smooth. The lifting lower mold 201 is also a rectangular structure. The guide column of the vulcanizer 1 can provide guidance for the up and down movement of the lifting lower mold 201 to ensure that it does not deviate during the lifting process. The mold cavity 2011 at the top of the lifting lower mold 201 is completely matched with the mold cavity 2011 of the fixed upper mold 202 in shape and size. After the two are molded together, a complete insulator molding space can be formed. The placement frame 4 can move synchronously with the lifting lower mold 201 and will not get loose during the movement.

[0029] For example, Figure 3 As shown, when the core rod and rubber strip need to be placed, the lifting lower mold 201 slowly descends under the action of the drive mechanism, and then the material rack 3 is deflected so that the placement frame 4 reaches a height that is convenient for the operator to place the materials. The operator places the core rod and rubber strip in the placement frame 4 in sequence. After placement, the material rack 3 swings vertically, the lifting lower mold 201 begins to rise, and the placement frame 4 rises along with the lifting lower mold 201. When the lifting lower mold 201 rises to contact the fixed upper mold 202, the two molds are closed to form a closed molding space, and the vulcanizer 1 begins to heat, pressurize and vulcanize the material in the mold 2. After vulcanization is completed, the lifting lower mold 201 descends again, and the placement frame 4 also descends. Then the material rack 3 swings in the opposite direction, and the operator can easily remove the molded insulator from the placement frame 4.

[0030] In some examples, the material rack 3 includes a rotating shaft 32, which is rotatably connected to the outer wall of the lifting lower mold 201; there are two side beams 31, and the two side beams 31 are respectively arranged at the two ends of the rotating shaft 32, and the side beams 31 can swing vertically along the rotating shaft 32; a slide 310 is opened on the side beam 31 along its length direction, and a slider 33 is slidingly arranged in the slide 310, and the outer wall of the placement frame 4 is fixedly connected to the outer wall of the slider 33. The number of sliders 33 is the same as that of the placement frame 4, and each placement frame 4 corresponds to a slider 33.

[0031] For example, Figure 3As shown, both ends of the rotating shaft 32 of the material rack 3 are mounted on the outer wall of the lifting lower mold 201 through bearings. The bearings can provide good support and rotation performance, so that the rotating shaft 32 can rotate smoothly. Two side beams 31 are respectively mounted on the two ends of the rotating shaft 32. A slide 310 is provided on the side beam 31 along its length. The slider 33 is U-shaped and can slide along the slide. From the bottom of the slide 310 to the top of the slide 310, the diameter of the slider 33 gradually decreases. Adjacent sliders 33 can be interlocked so that adjacent placement frames 4 can fit together. The four corners of the placement frame 4 are fixedly connected to the four sliders 33 by bolts or welding. Each placement frame 4 corresponds to a slider 33 to ensure that the placement frame 4 is firmly and stably installed on the side beam 31.

[0032] During the swinging process, the placement frame 4 slides slightly within the slideway 310 via the slider 33. As the side beam 31 swings toward the vulcanizer 1, the placement frame 4 gradually approaches the mold 2. When the side beam 31 swings to a specified angle, the placement frame 4 moves the material above the mold 2. After vulcanization is complete, the side beam 31 swings in the opposite direction, and the placement frame 4 follows the side beam 31. The slider 33 slides within the slideway 310 to remove the formed insulator from the mold 2.

[0033] In some examples, the side beam rod 31 has an opening 311 facing the fixed upper mold 202, and the opening 311 is connected to the slide 310; a fixed rod 5 is provided on the outer wall of the top surface of the vulcanizer 1, and the fixed rod 5 is arranged parallel to the rotating shaft 32. The side beam rod 31 can swing vertically along the rotating shaft 32 so that the side beam rod 31 is connected to the fixed rod 5 through the opening 311, and when the side beam rod 31 moves with the lifting lower mold 201, the side beam rod 31 can move along the fixed rod 5 through the slide 310 so that the fixed rod 5 pushes the slider 33.

[0034] For example, Figure 3 As shown, a U-shaped opening 311 is provided on the side of the side beam 31 facing the fixed upper mold 202. The opening 311 is connected to the slideway 310. The opening 311 ensures that the side beam 31 is smoothly connected to the fixed rod 5 during the swinging process. The fixed rod 5 is a cylindrical structure, fixedly mounted on the outer wall of the top surface of the vulcanizer 1. The length of the fixed rod 5 is adapted to the length of the side beam 31, and the fixed rod 5 is arranged parallel to the rotating shaft 32. When the side beam 31 swings to a certain angle, it can be inserted into the fixed rod 5 through the opening 311, and the side beam 31 can slide along the fixed rod 5 in the slideway 310.

[0035] The side beam 31 begins to swing vertically around the rotating shaft 32. When it swings to a position aligned with the fixed rod 5, the U-shaped opening 311 of the side beam 31 is sleeved on the fixed rod 5. At this time, the side beam 31 moves along with the lifting lower mold 201. Due to the connection between the side beam 31 and the fixed rod 5, the side beam 31 can move along the fixed rod 5. During the movement, the fixed rod 5 will push the slider 33, thereby driving the placement frame 4 to move, so that the multiple placement frames 4 are close to each other and close to the mold 2. Through the interaction between the fixed rod 5 and the slider 33, the placement frame 4 can accurately place the material on the mold 2 according to the predetermined path, or remove the formed insulator from the mold 2. When the operation is completed, the side beam 31 swings in the opposite direction, breaks away from the connection with the fixed rod 5, and returns to the initial position.

[0036] Compared to the traditional method of relying solely on the swing of the material rack 3 to control the position of the placement frame 4, the fixed rod 5 and the slide 310 cooperate to more accurately control the movement trajectory of the placement frame 4, avoiding the problem of inaccurate material placement caused by swing angle errors or other factors. At the same time, the supporting role of the fixed rod 5 also enhances the stability of the side beam 31 during operation, improving the reliability of equipment operation and production accuracy.

[0037] In some examples, a guide rod 34 is provided on the outer wall of the side beam rod 31, and a plurality of rings 35 are slidably provided on the guide rod 34. Each ring 35 is fixedly connected to a slider 33, and a spring 36 is provided between adjacent rings 35. The spring 36 is used to push the ring 35.

[0038] For example, Figure 3 As shown, two parallel guide rods 34 are fixedly mounted on the outer wall of the side beam 31. The guide rods 34 are made of stainless steel with a polished surface for excellent finish and wear resistance. Multiple collars 35 are slidably mounted on the guide rods 34. Each collar 35 is fixedly connected to a slider 33 via bolts, ensuring synchronized movement of the collar 35 and the slider 33. A spring 36 is installed between adjacent collars 35. The spring 36 is a compression spring, with its ends fixed to adjacent collars 35. The spring 36 ensures a certain buffering effect between the collars 35 while providing sufficient restoring force. It can be understood that when vulcanization is completed, under the buffering action of the spring 36, the shell of the insulator will not be quickly demolded from the mold 2, but will rely on the buffering of the spring 36 to achieve demolding at a slow speed first and then a fast speed. This can ensure that the shell of the insulator is not damaged due to slight adhesion to the mold cavity 2011. At the same time, since the core rod is clamped on the placement frame 4, under the action of the spring 36, when the mold 2 is opened, the core rod will still be on the placement frame 4 and will not be damaged due to demolding.

[0039] During the movement of the placement frame 4, if it encounters an external force, such as a push from the fixed rod 5 or the mutual compression of multiple placement frames 4, the slider 33 drives the collar 35 to slide on the guide rod 34, compressing the spring 36 between adjacent collars 35. The compression of the spring 36 absorbs the impact of the external force, acting as a buffer and preventing the placement frame 4 from shaking or shifting violently due to excessive impact. When the external force disappears, the spring 36 recovers its deformation, pushing the collar 35, restoring the adjacent sliders 33 to their original spacing, and the placement frame 4 also returns to its normal operating position. Throughout this process, the guide rod 34 provides stable guidance for the movement of the collar 35 and slider 33, ensuring the linearity and accuracy of the movement of the placement frame 4.

[0040] The arrangement of spring 36 and collar 35 provides excellent cushioning and reset functions for the movement of placement frame 4. During operation, various impacts and vibrations are inevitable. The cushioning effect of spring 36 effectively reduces the impact of these external forces on placement frame 4 and the materials, ensuring the stability of the materials during transportation. Furthermore, the reset function of spring 36 returns placement frame 4 to its correct position, improving the operating efficiency and reliability of the equipment.

[0041] In some examples, a sleeve 37 is provided at the bottom of the collar 35 , and the sleeve 37 is used to accommodate the compressed spring 36 so that adjacent sliders 33 fit together after being squeezed.

[0042] For example, Figure 3 As shown, a sleeve 37 is fixedly connected to the bottom of the collar 35. Sleeve 37 is a cylindrical structure with an inner diameter slightly larger than the outer diameter of the spring 36 and a height sufficient to accommodate the maximum compressed length of the spring 36. When adjacent sliders 33 are pressed against each other by a large external force, the spring 36 is compressed and completely accommodated within the sleeve 37. At this time, the sleeve 37 can protect the spring 36 and prevent it from twisting or deforming during the compression process.

[0043] During operation, when multiple placement frames 4 are simultaneously placed near the mold 2 to vulcanize the material and form the insulator, a significant compressive force is applied between adjacent sliders 33. In this situation, the sliders 33 drive the collars 35 toward each other, compressing the springs 36 and gradually inserting them into the sleeves 37. Due to the restraining effect of the sleeves 37, the springs 36 maintain a straight, compressed state without bending or skewing. When the compressive force disappears, the springs 36 return to their original shape within the sleeves 37, pushing the collars 35 and sliders 33 back into their original position, restoring the normal spacing between adjacent sliders 33 and returning the placement frames 4 to their normal operating state.

[0044] The provision of sleeve 37 provides a safe and reliable storage space for spring 36, allowing adjacent placement frames 4 to fit closely together after being squeezed and to perform vulcanization. This also prevents spring 36 from losing its elasticity or being damaged due to twisting or deformation, ensuring long-term stable operation of spring 36 and thus ensuring the proper performance of the cushioning and reset functions of placement frame 4. Furthermore, the presence of sleeve 37 makes the device structure more compact and rational, reduces interference or collision issues that could arise from exposed spring 36, and improves the safety and stability of device operation.

[0045] A strip groove is opened on the two side beams 31, and both ends of the rotating shaft 32 are set in the strip groove. A compression spring is set in the strip groove. When the lifting lower mold moves up and fits with the fixed upper mold, the compression spring is compressed to make the lifting lower mold and the fixed upper mold fit tightly.

[0046] In some examples, the placement frame 4 includes a first placement frame 41 for placing the core rod; there are two second placement frames 42, which are symmetrically arranged on the upper and lower sides of the first placement frame 41, and the second placement frames 42 are used to place the rubber strip.

[0047] For example, Figure 3 、 Figure 4 and Figure 5 As shown, the placement frame 4 consists of a first placement frame 41 and two second placement frames 42. The first placement frame 41 is rectangular in shape, with a semicircular slot 410 extending along its length. The slot 410 is sized to match the diameter of the mandrel, allowing it to fit tightly within the slot. A soft rubber pad is affixed to the inner wall of the slot 410. This elastic pad secures the mandrel while protecting its surface from damage. The two second placement frames 42 are symmetrically positioned above and below the first placement frame 41. Both are rectangular frames, effectively securing the rubber strip and preventing it from sliding within the placement frame 4.

[0048] During the production preparation phase, the operator first places the core rod into the slot 410 of the first placement frame 41. The ends of the core rod are securely held in place by the slots 410 and rubber pads. The rubber strip is then placed into each of the two second placement frames 42, secured in place by the protruding strips. Once placed, the material rack 3 drives the placement frames 4 to transport the material onto the mold 2. The core rod in the first placement frame 41 and the rubber strip in the second placement frame 42 precisely fall into the mold cavity 2011 of the mold 2. After vulcanization is complete, the placement frames 4 remove the formed insulator from the mold 2, allowing the operator to easily remove the insulator from the placement frames 4.

[0049] The slots 410 and rubber pads of the first placement frame 41 prevent the core rod from rotating or shifting during transportation and vulcanization. The protrusions of the second placement frame 42 effectively secure the rubber strip, preventing it from sliding within the placement frame 4. This design ensures the stability of the material within the placement frame 4, thereby guaranteeing the molding quality of the insulator, reducing product defects caused by material shifting, and improving the production yield.

[0050] In some examples, the first placement frame has a card slot 410, which is used to clamp with both ends of the core rod; the second placement frame 42 is hingedly provided with a card plate 43 at the corners, and the card plate 43 is used to fix the corners of the rubber strip.

[0051] For example, Figure 4 As shown, the corners of the second placement frame 42 are each mounted with a clip 43 via a hinge axis. The clip 43 is in the shape of a long strip, with one end hinged to the corner of the second placement frame 42 and the other end pivotable about the hinge axis. The surface of the clip 43 is also provided with an anti-slip texture, which increases friction with the rubber strip and better secures the rubber strip.

[0052] When placing the mandrel, align the two ends of the mandrel with the positioning grooves at both ends of the slot 410 of the first placement frame 41, then place the mandrel into the slot 410. The mandrel is firmly fixed by the slot 410 and the positioning groove. When placing the rubber strip, first place the rubber strip in the second placement frame 42 so that its corners are aligned with the corners of the second placement frame 42, and then rotate the card plate 43 so that the card plate 43 presses the corners of the rubber strip. The anti-slip texture on the surface of the card plate 43 is in close contact with the rubber strip, providing sufficient friction to prevent the rubber strip from moving. When the material rack 3 drives the placement frame 4 to transport the material to the mold 2 and during the vulcanization process, the mandrel and the rubber strip can maintain a stable position. After vulcanization is completed, due to the shrinkage process during vulcanization, the card plate 43 can be separated from the rubber strip without the operator manually rotating the card plate 43. The anti-skid texture on the surface of the clamping plate 43 increases the fixing force of the rubber strip, effectively preventing the rubber strip from sliding or shifting in the placement frame 4, thereby ensuring the molding quality of the insulator and reducing product defects caused by loose material fixation.

[0053] In some examples, a through hole 420 is provided at the corner of the second placement frame 42, an arc-shaped protrusion 430 is provided near the through hole 420 of the card plate 43, a telescopic push rod 6 is provided on the vulcanizer 1, and a spiral guide groove 601 is provided on the outer peripheral wall of the telescopic push rod 6. The arc-shaped protrusion 430 is slidably connected to the spiral guide groove 601. After the telescopic push rod 6 moves upward and extends into the through hole 420, the arc-shaped protrusion 430 can enter the spiral guide groove 601, so that the spiral guide groove 601 guides the card plate 43 to deflect and open toward the outside of the second placement frame 42.

[0054] For example, Figure 4 、 Figure 6 and Figure 7 As shown, a circular through-hole 420 is formed at a corner of the second placement frame 42. The diameter of the through-hole 420 is slightly larger than the outer diameter of the telescopic push rod 6. A curved protrusion 430 is provided on the clamping plate 43 near the through-hole 420. The curved protrusion 430 is a hemispherical structure with a smooth surface and a certain degree of hardness. The telescopic push rod 6 installed on the vulcanizer 1 is driven by an electric push rod. A spiral guide groove 601 is machined into its outer peripheral wall. The pitch and depth of the spiral guide groove 601 are calculated to perfectly match the curved protrusion 430. A stop block is also installed on the top of the telescopic push rod 6 to limit the height of the telescopic push rod 6.

[0055] During the vulcanization process, the telescopic push rod 6 is in a retracted state and does not contact the clamping plate 43. During vulcanization, the telescopic push rod 6 begins to move upward, driven by the electric push rod, gradually extending into the through-hole 420 at the corner of the second placement frame 42. As the telescopic push rod 6 rises, the spiral guide groove 601 on its outer wall contacts and interacts with the arc-shaped protrusion 430 on the clamping plate 43. Due to the unique shape of the spiral guide groove 601, the arc-shaped protrusion 430 is subjected to a tangential force as it slides within the spiral guide groove 601, causing the clamping plate 43 to deflect and open around the hinge axis toward the outside of the second placement frame 42. At this time, the anti-slip texture on the interior of the clamping plate 43 exerts an outward tensile force on the corners of the rubber strip, effectively tightening the rubber strip. This not only prevents the rubber strip from shrinking, but also allows the rubber strip to vulcanize in a relatively tight state in contact with the mandrel, improving the vulcanization effect. When the telescopic push rod 6 rises to the height of the stop block, the clamping plate 43 fully opens, releasing its grip on the rubber strip. When the next rubber strip needs to be installed, the clamping plate 43 only needs to be opened manually.

[0056] In some examples, the outer wall of the vulcanizer 1 is provided with an oblique support rod 7, and the oblique support rod 7 is used to support the material rack 3 in a horizontal state.

[0057] For example, Figure 6 As shown, a diagonal brace 7 is welded to the outer wall of the vulcanizer 1. The diagonal brace 7 is a triangular truss structure welded from multiple high-strength steel pipes. This structure can reduce its own weight while ensuring strength. One end of the diagonal brace 7 is fixed to the outer wall of the vulcanizer 1 by welding, and the other end is provided with an adjustable support head. The support head is a spherical structure that can make good contact with the surface of the material rack 3. The support head is connected to the diagonal brace 7 by a thread. The operator can adjust its extension length by rotating the support head to adapt to the support requirements of the material rack 3 in different states. The triangular truss structure of the diagonal brace 7 can effectively disperse the weight of the material rack 3 and the placement frame 4, ensuring that the material rack 3 remains stable in the horizontal position.
