Description

Technical Field

[0001] This utility model relates to the technical field of vulcanized rubber production equipment, specifically to a rubber vulcanizing machine suitable for the production of rubber products. Background Technology

[0002] Rubber vulcanization is a process of chemically modifying rubber. By adding vulcanizing agents, such as sulfur, and under certain temperature, pressure, and time conditions, cross-linking is formed between the molecular chains of rubber. This can significantly improve the physical properties of rubber, such as increased elasticity, increased tensile strength, and better wear resistance. It can also improve the anti-aging ability of rubber, allowing rubber products to be used in more complex environments. It is widely used in the production of rubber products such as tires and hoses.

[0003] Operators frequently use rubber vulcanizing machines when producing rubber products to manufacture stable and high-performance vulcanized rubber products. However, while existing rubber vulcanizing machines have basic rubber vulcanization functions, rubber particles typically adhere to the lower surface of the upper mold and the bottom surface of the lower mold after production. Operators need to manually clean these particles before proceeding to the next production run. However, the high temperature of the vulcanized rubber particles makes this manual cleaning method time-consuming, labor-intensive, and somewhat dangerous. Therefore, improvements are needed.

[0008] As a preferred technical solution of this utility model, a vulcanizing mold located on the right side of the lower scraper is fixedly installed on the inner surface of the workbench. A movable template is movably connected to the bottom of the inner surface of the vulcanizing mold. A heating plate is fixedly installed on the inner surfaces of both the vulcanizing mold and the movable template. A top rod is fixedly connected to the bottom end of the movable template. The bottom end of the top rod passes through the workbench and extends into the interior of the support base and is fixedly connected to a rectangular rod. The outer surface of the front end of the rectangular rod is movably connected to the inner surface of the upper side of the driving rod.

[0009] As a preferred technical solution of this utility model, a second limiting rod is fixedly connected to the lower surface of the workbench. The bottom end of the second limiting rod passes through the rectangular rod and extends to the lower side of the rectangular rod. The outer surface of the second limiting rod and the inner surface of the rectangular rod are movably connected.

[0010] As a preferred technical solution of this utility model, a second motor is fixedly installed on the right surface of the support base, and a double-threaded rod is fixedly sleeved on the other end of the output shaft of the second motor. The left end of the double-threaded rod passes through the support base and extends into the interior of the support base. A movable block located inside the support base is threadedly sleeved on the outer surface of the double-threaded rod. There are two movable blocks, and the outer surfaces of the two movable blocks are respectively movably connected to the inner surfaces of the lower side of the two driving rods.

[0011] As a preferred technical solution of this utility model, a No. 3 limiting rod is fixedly connected to the right surface of the support base, which is located above the double-threaded rod. The left end of the No. 3 limiting rod passes through the support base and the moving block in sequence and extends into the interior of the support base. The outer surface of the No. 3 limiting rod and the inner surface of the moving block are movably sleeved together.

[0012] As a preferred technical solution of this utility model, a support block is fixedly connected to the rear side of the upper surface of the workbench, an mounting plate is fixedly connected to the top of the support block, an upper pressing mold located directly above the movable template is movably connected to the front side of the lower surface of the mounting plate, a second heating plate is fixedly installed on the inner surface of the upper pressing mold, and the lower surface of the upper pressing mold and the upper surface of the upper scraper are flush.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model, by setting up a lower scraper, a connecting plate, an upper scraper, a driving rod, and a driven rod, ensures that when the upper mold contacts the mounting plate and the upper surface of the movable template is on the same plane as the upper surface of the worktable, the operation of motor number one will cause the circular shaft and the driving rod to start rotating. At this time, the rotation of the driving rod will drive the driven rod, causing the driven rod to start rotating about the other end of the driving rod as the axis. At the same time, the other end of the driven rod will drive the connecting plate, causing the connecting plate to start moving to the right. During the movement of the lower and upper scrapers, the adhesive rubber particles below the upper mold and above the movable template will be automatically cleaned by the lower and upper scrapers, thereby solving the problem of time-consuming, labor-intensive, and inefficient manual cleaning of adhesive rubber particles.

[0017] 2. This utility model, by setting up a movable template, a rectangular rod, a driving rod, a double-threaded rod, and moving blocks, allows the double-threaded rod to rotate when the second motor starts running. At this time, the two moving blocks will move towards each other under the limit of the third limiting rod. As the moving blocks move, the two driving rods will start to rotate around the fixed axis under the drive of the two moving blocks. At the same time, the inner surface of the upper side of the driving rod will drive the rectangular rod, causing the rectangular rod, the top rod, and the movable template to move upward as a whole. Finally, the high-temperature vulcanized rubber product located above the movable template will be pushed out of the worktable by the movable template, thereby avoiding the problem that the rubber product is too hot after vulcanization and difficult to remove from the vulcanization mold.

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0027] like Figures 1 to 6 As shown, this utility model provides a rubber vulcanizing machine suitable for rubber product manufacturing, including a workbench 1. A lower scraper 2 is movably connected to the left side of the upper surface of the workbench 1. A connecting plate 3 is fixedly connected to the left surface of the lower scraper 2. An upper scraper 4 is fixedly connected to the top of the right surface of the connecting plate 3. A first motor 5 is fixedly installed on the left surface of the workbench 1. A round shaft 6 is fixedly sleeved at the other end of the output shaft of the first motor 5. A driving rod 7 is fixedly sleeved on the outer surface of the round shaft 6. A driven rod 8 is hinged to the other end of the driving rod 7. The other end of the driven rod 8 is hinged to the outer surface of the connecting plate 3.

[0028] When the operator starts motor 5, the circular shaft 6 and the driving rod 7 will start to rotate. At this time, the rotation of the driving rod 7 will cause the other end of the driving rod 7 to drive the driven rod 8, thereby causing the driven rod 8 to start rotating as well. The other end of the driven rod 8 will drive the connecting plate 3, causing the connecting plate 3 to move to the right as a whole.

[0029] Among them, a fixed plate 9 is movably connected to the rear side of the left surface of the connecting plate 3. The bottom end of the fixed plate 9 is fixedly connected to the upper surface of the workbench 1. A first limiting rod 10 is movably sleeved on the left surface of the fixed plate 9. A first limiting plate 11 is fixedly connected to the left end of the first limiting rod 10. The right end of the first limiting rod 10 passes through the fixed plate 9 and extends to the left surface of the connecting plate 3 and is fixedly connected to the connecting plate 3.

[0030] The design of the fixed plate 9, the first limiting rod 10, and the first limiting plate 11 serves to limit the overall movement direction and range of the connecting plate 3.

[0031] Among them, a support base 12 is fixedly connected to the lower surface of the workbench 1, and a fixed shaft 19 is fixedly connected to the left and right sides of the front end of the inner surface of the support base 12. A drive rod 20 is hinged to the outer surface of the fixed shaft 19.

[0032] The design of the fixed shaft 19 allows the drive rod 20 to rotate around the fixed shaft 19 as the axis.

[0033] The inner surface of the workbench 1 is fixedly installed with a vulcanizing mold 13 located on the right side of the lower scraper 2. The bottom of the inner surface of the vulcanizing mold 13 is movably connected with a movable template 14. A heating plate 15 is fixedly installed on the inner surfaces of both the vulcanizing mold 13 and the movable template 14. A top rod 16 is fixedly connected to the bottom end of the movable template 14. The bottom end of the top rod 16 passes through the workbench 1 and extends into the interior of the support base 12 and is fixedly connected with a rectangular rod 17. The outer surface of the front end of the rectangular rod 17 is movably connected to the inner surface of the upper side of the driving rod 20.

[0034] The design of the No. 1 heating plate 15 can heat the rubber and vulcanizing agent mixture solution poured into the vulcanizing mold 13 and the movable template 14, thereby bringing the rubber and vulcanizing agent to the temperature conditions required for the vulcanization reaction.

[0035] Among them, the lower surface of the workbench 1 is fixedly connected to the second limiting rod 18. The bottom end of the second limiting rod 18 passes through the rectangular rod 17 and extends to the lower side of the rectangular rod 17. The outer surface of the second limiting rod 18 and the inner surface of the rectangular rod 17 are movably connected.

[0036] The design of the second limiting rod 18 restricts the overall movement direction of the rectangular rod 17 and the movable template 14.

[0037] Among them, a second motor 21 is fixedly installed on the right surface of the support base 12. A double-threaded rod 22 is fixedly sleeved at the other end of the output shaft of the second motor 21. The left end of the double-threaded rod 22 passes through the support base 12 and extends into the interior of the support base 12. A moving block 23 located inside the support base 12 is threadedly sleeved on the outer surface of the double-threaded rod 22. There are two moving blocks 23. The outer surfaces of the two moving blocks 23 are movably connected to the inner surfaces of the lower side of the two driving rods 20, respectively.

[0038] When motor 21 starts running, the double-threaded rod 22 will start to rotate.

[0039] Among them, the right surface of the support base 12 is fixedly connected to the third limiting rod 24 located above the double threaded rod 22. The left end of the third limiting rod 24 passes through the support base 12 and the moving block 23 in sequence and extends into the interior of the support base 12. The outer surface of the third limiting rod 24 and the inner surface of the moving block 23 are movably sleeved.

[0040] The design of the No. 3 limit rod 24 ensures the stability of the two moving blocks 23 during movement.

[0041] Among them, a support block 25 is fixedly connected to the rear side of the upper surface of the workbench 1, and a mounting plate 26 is fixedly connected to the top of the support block 25. An upper pressure mold 28 located directly above the movable template 14 is movably connected to the front side of the lower surface of the mounting plate 26. A second heating plate 29 is fixedly installed on the inner surface of the upper pressure mold 28. The lower surface of the upper pressure mold 28 is flush with the upper surface of the upper scraper 4.

[0042] Heating plate 29 has the same function as heating plate 15, both serving to heat the rubber and vulcanizing agent.

[0043] Among them, a pneumatic cylinder 27 located above the upper mold 28 is fixedly installed on the upper surface of the mounting plate 26. The bottom end of the pneumatic cylinder 27 penetrates the mounting plate 26 and extends to the upper surface of the upper mold 28 and is fixedly connected to the upper mold 28.

[0044] When the pneumatic cylinder 27 starts running, the upper mold 28 will begin to move downwards.

[0045] Among them, the upper surface of the upper mold 28 is fixedly connected to the fourth limiting rod 30 located on the left and right sides of the pneumatic cylinder 27. The top of the fourth limiting rod 30 passes through the mounting plate 26 and extends to the top of the mounting plate 26 and is fixedly connected to the second limiting plate 31. The outer surface of the fourth limiting rod 30 and the inner surface of the mounting plate 26 are movably sleeved.

[0046] The design of the fourth limiting rod 30 ensures that the overall movement direction of the upper mold 28 is always vertically downward, thus ensuring that the upper mold 28 can enter the interior of the vulcanizing mold 13.

[0047] Working principle and usage process of this utility model:

[0048] After the rubber product inside the vulcanizing mold 13 has vulcanized, the operator first starts the pneumatic cylinder 27, so that the upper surface of the upper mold 28 contacts the lower surface of the mounting plate 26. Then the operator starts the second motor 21. As the second motor 21 runs, the double-threaded rod 22 will rotate and cause the two moving blocks 23 to start moving towards each other. As the two moving blocks 23 move, the two driving rods 20 will start rotating around the fixed shaft 19 under the drive of the two moving blocks 23. At the same time, the inner surface of the upper side of the two driving rods 20 will drive the rectangular rod 17, so that the rectangular rod 17, the top rod 16 and the movable template 14 will start to move upward as a whole. As the movable template 14 moves, the high-temperature vulcanized rubber product inside the vulcanizing mold 13 will be gradually pushed out to the outside of the worktable 1 by the movable template 14 until the upper surface of the movable template 14 and the upper surface of the worktable 1 are flush.

[0049] Then the operator removes the high-temperature vulcanized rubber product and starts motor 5. As motor 5 runs, the shaft 6 and the drive rod 7 begin to rotate. The rotation of the drive rod 7 drives the driven rod 8, causing the driven rod 8 to rotate around the other end of the drive rod 7. At the same time, the other end of the driven rod 8 also drives the connecting plate 3, causing the connecting plate 3 to move to the right under the limit of the first limit rod 10. As the connecting plate 3 moves, the lower scraper 2 and the upper scraper 4 scrape off the rubber particles adhering to the upper surface of the movable template 14 and the lower surface of the upper mold 28, respectively, thus facilitating the next rubber vulcanization operation.

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
