Description

Technical Field

[0001] This utility model relates to the technical field of toothed V-belt processing tools, and in particular to a toothed V-belt processing mold. Background Technology

[0002] Toothed V-belts are industrial transmission belts that combine friction drive and toothed meshing principles, primarily used for the precise transmission of rotational power. Their toothed structure design offers advantages over ordinary V-belts, including better flexibility, faster heat dissipation, and anti-slip properties, making them suitable for applications with small-diameter pulleys and equipment requiring precise transmission. The manufacturing process involves placing a prepared belt blank (already wrapped with cord, compressed rubber, and fabric) onto a large cylindrical steel mold, also known as a "vulcanizing drum" or "belt drum." A tensioning sleeve (usually a flexible steel belt) is then wrapped around the outside, allowing it to undergo a vulcanization reaction under high temperature and pressure before demolding.

[0003] Most existing molds used for producing toothed V-belts are one-piece structures. During use, when the product needs to be demolded after vulcanization, the product is directly squeezed and pulled from the mold. This demolding method results in relatively large frictional resistance due to the large contact area between the product and the mold, thus increasing the difficulty of demolding the product.

[0004] Therefore, it is necessary to provide a new toothed V-belt processing mold to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a toothed V-belt processing mold.

[0006] The toothed V-belt processing mold provided by this utility model includes: a support cylinder and an arc-shaped mold piece, wherein multiple arc-shaped mold pieces are provided and distributed in a ring;

[0007] The outer wall of the support cylinder is provided with a plurality of annularly distributed first slots, and an installation slot is provided between each two adjacent first slots on the outer wall of the support cylinder. A slidingly connected installation plate is inserted into the installation slot, and a second slot is provided on the outer wall of the installation plate.

[0008] The inner walls of the first and second slots abut against the inner wall of the arc-shaped mold piece, and the side wall of the arc-shaped mold piece away from the center of the support cylinder is provided with a V-groove for machining the toothed V-belt.

[0009] The support cylinder is equipped with a linkage component that drives the mounting plate.

[0010] Preferably, the linkage component includes a top frame, which is fixedly installed at the end of the support cylinder. A plurality of rotatably connected rotating rods are fixedly installed on the inner top of the top frame. A rectangular block is fixedly connected to the outer wall of the rotating rod. A guide frame is rotatably connected to the bottom end of the rotating rod, and the outer wall of the guide frame is fixedly connected to the outer wall of the top frame.

[0011] Preferably, a slidingly connected linkage frame is inserted inside the guide frame, the inside of the linkage frame is threadedly connected to the outer wall of the rotating rod, and a fixedly connected mounting block is provided at the bottom end of the linkage frame, and the mounting block is fixedly connected to the mounting plate.

[0012] Preferably, a support column is fixedly installed inside the support cylinder. The support column is a polygonal column, and a sliding groove is provided on each side wall of the support column. The inner wall of the sliding groove abuts against and is slidably connected to the outer wall of the mounting block.

[0013] Preferably, the first slot has a first insertion hole, the second slot has a second insertion hole, and a rod is inserted into both the first and second insertion holes. The rod is fixedly connected to the inner wall of the corresponding arc-shaped mold piece, and a nut is fitted on the outer wall of the rod to fix it.

[0014] Preferably, the length of the mounting groove is greater than the length of the arc-shaped mold piece, and the V-shaped groove wall of the arc-shaped mold piece is located on the outer side of the outer wall of the support cylinder.

[0015] Compared with related technologies, the toothed V-belt processing mold provided by this utility model has the following beneficial effects:

[0016] 1. This utility model sets the mold used for toothed V-belt processing as a split structure. After the vulcanization production of the product is completed, when demolding is required, several arc-shaped mold pieces located on the mounting plate can be lifted and driven one by one to achieve initial demolding of the arc-shaped mold pieces and the product, reducing the contact area between the product and the arc-shaped mold pieces. As a result, when driving the product to demold later, the frictional resistance of demolding can be reduced, and the demolding smoothness of the product can be improved.

[0017] 2. By assembling and installing the arc-shaped mold pieces, this utility model allows for the independent replacement of any arc-shaped mold piece when the V-groove in one of the pieces is damaged due to impact during subsequent use, thereby reducing the cost of later maintenance and replacement.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Please see Figures 1 to 5 The present invention provides a toothed V-belt processing mold, which includes a support cylinder 1 and an arc-shaped mold plate 4, wherein the arc-shaped mold plate 4 is provided with multiple pieces arranged in a ring.

[0027] In the embodiments of this utility model, please refer to Figures 1 to 5 The outer wall of the support cylinder 1 has multiple annularly distributed first slots 12. An installation slot 11 is provided between two adjacent first slots 12 on the outer wall of the support cylinder 1. A slidingly connected installation plate 2 is inserted into the installation slot 11. A second slot 21 is provided on the outer wall of the installation plate 2. The inner walls of the first slots 12 and the second slots 21 abut against the inner wall of the arc-shaped mold 4. The side wall of the arc-shaped mold 4 away from the center of the support cylinder 1 is provided with a V-shaped groove for machining the toothed V-belt. A first insertion hole 121 is provided inside the first slot 12. A second insertion hole 22 is provided inside the second slot 21. An insertion rod 41 is inserted into both the first insertion hole 121 and the second insertion hole 22. The insertion rod 41 is fixedly connected to the inner wall of the corresponding arc-shaped mold 4. A nut is sleeved on the outer wall of the insertion rod 41 to fix it.

[0028] It should be noted that: after the multiple annularly distributed arc-shaped mold pieces 4 are assembled, they can form a complete cylindrical structure along the outer wall of the support cylinder 1. Thus, during use, the raw materials required for the processing of toothed V-belts can be smoothly wound on its outer wall so that they can be vulcanized into a toothed V-belt with a complete annular structure in the later stage.

[0029] Meanwhile, since multiple arc-shaped mold pieces 4 are inserted and installed in the first slot 12 and the second slot 21, when the V-shaped groove in a certain arc-shaped mold piece 4 is damaged due to bumps or other reasons during subsequent use, the arc-shaped mold piece 4 can be replaced and repaired independently, thereby reducing the maintenance and replacement costs in the later use.

[0030] In the embodiments of this utility model, please refer to Figures 1 to 5 The support cylinder 1 is provided with a linkage assembly 3 that drives the mounting plate 2. The linkage assembly 3 includes a top frame 31, which is fixedly installed at the end of the support cylinder 1. Multiple rotating rods 32 are fixedly installed on the inner top of the top frame 31. A rectangular block 321 is fixedly connected to the outer wall of the rotating rod 32. A guide frame 33 is rotatably connected to the bottom of the rotating rod 32. The outer wall of the guide frame 33 is fixedly connected to the outer wall of the top frame 31. A sliding linkage frame 34 is inserted inside the guide frame 33. The inside of the linkage frame 34 is threadedly connected to the outer wall of the rotating rod 32. A mounting block 341 is fixedly connected to the bottom of the linkage frame 34. The mounting block 341 is fixedly connected to the mounting plate 2.

[0031] It should be noted that after the vulcanization process of the product is completed, when demolding is required, the operator can take out a wrench and wrench it on the outside of the rectangular block 321 to control the rotation of the rotating rod 32. The rotating rod 32 will drive the linkage frame 34 to move inside the guide frame 33 through the threaded structure. At this time, the moving linkage frame 34 will drive the mounting plate 2 to move inside the mounting groove 11 through the mounting block 341, thereby driving the arc-shaped mold piece 4 on the mounting plate 2 to move synchronously. This allows the single arc-shaped mold piece 4 to separate from the inner wall of the product first, reducing the contact area between the inner wall of the product and the mold. In the later stage, when the product is driven to demold, the relatively small contact area can reduce the frictional resistance of the connection between the mold and the product during demolding, thereby helping to improve the smoothness of product demolding.

[0032] Furthermore, since the rotating rod and the linkage frame are connected by threads, during subsequent use, threaded rod protective sleeves can be fitted on both sides of the connection between the rotating rod and the linkage frame to protect the threads of the connection.

[0033] In the embodiments of this utility model, please refer to Figures 1 to 5A support column 13 is fixedly installed inside the support cylinder 1. The support column 13 is a polygonal column. Each side wall of the support column 13 is provided with a sliding groove 131, and the inner wall of the sliding groove 131 abuts against and slides with the outer wall of the mounting block 341.

[0034] It should be noted that: through the installation of the support column 13, when the linkage component 3 is operated during use and the mounting block 341 is moved to slide, the slide groove 131 can limit the horizontal movement of the mounting block 341 by abutting against it, thus preventing the mounting block 341 from moving arbitrarily in the horizontal direction. At the same time, it can also improve the horizontal lateral stability of the linkage frame 34 and the guide frame 33. Therefore, the linkage component 3 can stably drive the mounting plate 2 to move in the vertical direction.

[0035] In the embodiments of this utility model, please refer to Figures 1 to 5 The length of the mounting groove 11 is greater than the length of the arc-shaped mold 4, and the V-shaped groove wall of the outer wall of the arc-shaped mold 4 is located on the outer side of the outer wall of the support cylinder 1.

[0036] It should be noted that since the V-groove in the arc-shaped mold plate 4 is on the outermost side, when demolding the processed product later, the outer wall of the support cylinder 1 can avoid obstructing the demolding trajectory of the product, allowing the product to be smoothly removed from the outer wall of the arc-shaped mold plate 4.

[0037] The working principle of the toothed V-belt processing mold provided by this utility model is as follows:

[0038] When using this device, the operator can wind the raw materials to be processed by the toothed V-belt onto the device in sequence as needed. After winding, the device can be placed in an external vulcanizing unit for vulcanization processing.

[0039] After the toothed V-belt vulcanization process is completed and it is removed from the external vulcanization device, the wrench is taken out and locked on the outside of the rectangular block 321 to control the rotation rod 32 to rotate. The rotating rod 32 will drive the linkage frame 34 to move inside the guide frame 33 through the threaded structure. At this time, the moving linkage frame 34 will drive the mounting plate 2 to move inside the mounting groove 11 through the mounting block 341, thereby driving the arc-shaped mold piece 4 located on the mounting plate 2 to move synchronously. Therefore, the corresponding arc-shaped mold piece 4 can be separated from the vulcanized product.

[0040] By repeating the above steps, the number and area of ​​the arc-shaped mold pieces 4 in contact with the toothed V-belt in this device can be reduced. As a result, when the operator drives the arc-shaped mold pieces 4 to demold them, the frictional resistance during demolding can be reduced, thus making the demolding of the product smoother.

[0041] Furthermore, since the arc-shaped mold plate 4 is inserted and installed, if the V-groove in the arc-shaped mold plate 4 is damaged due to impact during subsequent use, the nut on the outer wall of the insert rod 41 in the arc-shaped mold plate 4 can be unscrewed to release the limit on the insert rod 41, and the arc-shaped mold plate 4 can be taken out to achieve independent replacement of the damaged arc-shaped mold plate 4, thereby reducing the usage cost of later maintenance and replacement of this device.

[0042] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
