[0002] The rubber grouped narrow V-belt is a belt commonly used in mechanical transmission. It combines the efficient transmission performance of narrow V-belts with the stability of grouped design. Its cross-section height is higher than that of ordinary V-belts and its width is narrower. It can work on smaller pulleys and transmit greater power. It is suitable for high-speed and high-load environments.

[0003] During the V-belt production process, due to the characteristics of the V-belt, the rubber group narrow V-belt needs to be demolded after production. However, the mold used to produce the rubber group narrow V-belt has a high temperature and a certain degree of viscosity. The V-belt is easily adhered to the teeth and in the mold. In addition, the V-belt is generally thin after production. If it is directly removed, it is easy to cause the newly produced V-belt to tear and be damaged.

[0004] Therefore, it is necessary to provide a new rubber group narrow V-belt production device that is easy to demould to solve the above technical problems. Utility Model Content

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0026] See also Figures 1 to 6 The present invention provides a rubber-bonded narrow V-belt production device that is easy to demould, and the rubber-bonded narrow V-belt production device that is easy to demould comprises:

[0027] A vulcanizer body 1, and a lower hot platen 11 and an upper hot platen 12 provided on the vulcanizer body 1. A hydraulic cylinder 13 is installed on the vulcanizer body 1 to drive the lower hot platen 11 to move vertically and fit into the upper hot platen 12. The upper hot platen 12 is fixedly mounted on the vulcanizer body 1 and is located directly above the lower hot platen 11.

[0028] The mounting base 2 is mounted on the lower hot template 11, and a forming base plate 3 is mounted on the mounting base 2. A number of V-grooves 301 are evenly provided on the forming base plate 3, and an ejection groove 302 is provided in the middle of several of the V-grooves 301. An ejection assembly 4 for ejecting the narrow V-belt after vulcanization is mounted on the mounting base 2. The ejection assembly 4 includes a lifting plate 41. A number of connecting springs 42 are fixedly mounted on the bottom end of the lifting plate 41. The ends of several connecting springs 42 facing away from the lifting plate 41 are fixedly connected to the mounting base 2. A top plate 43 that is plugged into the ejection groove 302 is mounted on the top of the lifting plate 41. A lower pressing assembly 5 for pressing the lifting plate 41 into place is installed on the upper hot template 12.

[0029] Both ends of the lifting plate 41 extend out of the mounting base 2 and are both equipped with docking seats 44 that are plugged into the down-pressing component 5. The down-pressing component 5 includes a pressing plate 51, which is detachably mounted on the bottom end of the upper hot template 12 by screws, and down-pressing blocks 52 are installed at both ends of the pressing plate 51. The down-pressing blocks 52 are plugged into the slots provided in the docking seats 44, and side guard plates 53 are installed on both sides of the pressing plate 51 by screws.

[0030] It should be noted that: when in use, the raw rubber, fillers and additives are mixed evenly in the internal mixer to form a vulcanizable rubber compound. After filtering the rubber to remove impurities, the sheet blank is placed on the molding base plate 3. After alignment, the hydraulic cylinder 13 is controlled by the vulcanizer body 1 to drive the lower hot template 11 to move toward the upper hot template 12. After moving to the slot opened by the lower pressing block 52 and inserting it into the docking seat 44, the mold is continued to be closed until the lower hot template 11 and the upper hot template 12 are fully fitted together. When they are fully fitted together, the lower pressing block 52 presses the lifting plate 41 to the top of the limit plate 22. At this time, the lifting plate 41 drives the top plate 43 to move down to the position aligned with the ejection groove 30. 2 is fitted so that it is flush with the bottom of the V-shaped groove 301, so that the strip blank can be vulcanized and formed in the molding cavity formed by the V-shaped groove 301 of the molding base plate 3 and the side guard plate 53. After complete vulcanization and molding, the hydraulic cylinder 13 controls the lower hot plate 11 to move away from the upper hot plate 12. When moving away, when the pressing plate 51 moves away from the molding base plate 3, the lifting plate 41 is driven to return upward under the action of the connecting spring 42. When returning to its original position, the ejector plate 43 is driven to eject the formed V-belt from the V-shaped groove 301 through the ejection groove 302, which facilitates the demoulding of the rubber group narrow V-belt molding. After being completely ejected, it can be easily removed from the molding base plate 3.

[0031] Among them, the limiting plates 22 for limiting the downward movement of the lifting plate 41 are evenly installed on the mounting base 2, wherein the height of the limiting plates 22 is such that when the lifting plate 41 and the top end of the limiting plate 22 are in contact with each other, the top end of the top plate 43 is flush with the bottom end of the V-shaped groove 301, and the length and width of the top plate 43 are respectively equal to the groove length and groove width of the ejection groove 302, so that when the mold is closed, the top end of the top plate 43 is flush with the bottom end of the V-shaped groove 301, forming a complete molding cavity, so that the vulcanization molding of the belt blank is complete, and the interference of the top plate 43 and the ejection groove 302 on the surface molding of the V-belt is reduced.

[0032] It should also be noted that: here, when the top plate 43 is not inserted into the docking seat 44 by the lower pressing block 52, the top plate 43 extends from the ejection groove 302 under the action of the spring force of the connecting spring 42. At this time, the strip blank is placed on the forming base plate 3. When the lower hot template 11 moves upward and approaches the upper hot template 12, the lower pressing block 52 contacts the docking seat 44, and the docking seat 44 is pressed down, thereby pressing the lifting plate 41 to move downward. The lifting plate 41 simultaneously drives the top plate 43 to move downward along the ejection groove 302 until the lower hot template 11 and the upper hot template 12 are completely molded, and the top plate 43 is just pushed away from the ejection groove 302. At this time, the top of the top plate 43 is flush with the bottom of the V-shaped groove 301.

[0033] In the embodiments of the present invention, please refer to Figures 1 to 6 , the mounting base 2 is detachably mounted on the lower hot template 11 by screws;

[0034] It should be noted that this facilitates the replacement of different mounting bases 2 on the lower hot plate 11 , thereby enabling molding base plates 3 of different specifications to be mounted on the lower hot plate 11 for vulcanization molding processing.

[0035] Furthermore, the molding base plate 3 is movably connected to the mounting base 2, and T-slots 303 are provided on both sides of the molding base plate 3. The top of the mounting base 2 is provided with a T-shaped protrusion 21 that is plugged into the T-slot 303. In this way, the molding base plate 3 is engaged with the T-slot 303 by using the T-slot 303. After engagement, the top plate 43 is inserted into the ejection groove 302 for limiting, thereby realizing rapid engagement of the molding base plate 3 and rapid installation of the molding base plate 3, which is convenient for later disassembly and replacement.

[0036] The working principle of the rubber combined narrow V-belt production device that is easy to demould provided by the utility model is as follows:

[0037] When in use, the mounting base 2 is installed on the lower hot template 11 by screws, and the pressing plate 51 is installed on the upper hot template 12, and then the forming base plate 3 is engaged with the T-shaped protrusion 21 by using the T-slot 303. After engaging, the top plate 43 is inserted into the ejection groove 302 for limiting, thereby realizing the rapid connection of the forming base plate 3 and the rapid installation of the forming base plate 3, which is convenient for later disassembly and replacement, and then the side guard plates 53 matching the forming base plate 3 are installed on both sides of the pressing plate 51. After installation, the raw rubber, filler and additives are mixed evenly in the internal mixer to form a vulcanizable rubber material. The sheet blank is placed on the forming base plate 3 after the rubber is filtered to remove impurities. After alignment, the hydraulic cylinder 13 is controlled by the vulcanizer body 1 to drive the lower hot template 11 to move toward the upper hot template 12. After moving to the slot opened by the lower pressing block 52 and the docking seat 44, as it continues When the mold is fully vulcanized, the lower hot template 11 is controlled by the hydraulic cylinder 13 to move away from the upper hot template 12. When the mold is fully vulcanized, the lower pressing block 52 presses the lifting plate 41 to the top of the limit plate 22. At this time, the lifting plate 41 drives the top plate 43 to move down and fit with the ejection groove 302, so that it is flush with the bottom of the V-shaped groove 301, so that the strip blank can be vulcanized in the molding cavity composed of the V-shaped groove 301 of the molding base plate 3 and the side guard plates 53. When fully vulcanized, the lower hot template 11 is controlled by the hydraulic cylinder 13 to move away from the upper hot template 12. When moving away, when the pressing plate 51 is away from the molding base plate 3, the lifting plate 41 is driven to reset upward under the action of the connecting spring 42. When resetting, the top plate 43 is driven to eject the formed V-belt from the V-shaped groove 301 from the ejection groove 302, which is convenient for the rubber group narrow V-belt molding demoulding. After being fully ejected, it can be easily removed from the molding base plate 3.

[0038] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0039] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
