Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of rubber molding, in particular to a bladder vulcanizer for producing rubber tires. Background Art
[0002] In the production process of rubber tires, bladder vulcanizers are key equipment, and their performance is directly related to production efficiency and product quality. When faced with the need to switch product models, the upper and lower mold connection structures of existing bladder vulcanizers are usually more complicated, and mostly use bolt fastening or other cumbersome mechanical connection methods. When the mold needs to be replaced to adapt to the production of different products, workers first need to use a variety of professional tools, such as wrenches, to loosen a large number of bolts in different distribution positions one by one. This process not only requires workers to have certain operating skills, but also due to the large number of bolts and limited operating space, the operation is difficult and extremely time-consuming and energy-consuming. According to actual production data statistics, it takes an average of several hours to complete a routine upper and lower mold disassembly.
[0003] After disassembly, transporting the old mold and installing the new one are equally arduous tasks. Due to the mold's large size and weight, handling and positioning often require the assistance of large lifting equipment such as a crane, and the collaboration of multiple personnel. Once the new mold is in place, it must be precisely fastened again using bolts and other fasteners to ensure it can withstand the tremendous pressure and prevent displacement during the vulcanization process. Any deviation in this process could result in an insecure mold installation, compromising the quality of the tire vulcanization. Summary of the Invention

DETAILED DESCRIPTION
[0051] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific embodiments of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other embodiments can be obtained based on these drawings without inventive work.
[0052] To simplify the drawings, only portions relevant to the invention are schematically depicted in each figure; they do not represent the actual structure of the product. Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one component with the same structure or function is schematically depicted or labeled. In this document, "one" not only means "only one" but also "more than one," and "several" includes "two" and "more than two."
[0053] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.
[0054] 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.
[0055] Reference Figures 1 to 6 , which is the first embodiment of the present invention, proposes a bladder vulcanizer for rubber tire production, including a frame 1; a first sliding frame 2 is vertically slidably arranged on the frame 1; an upper mold mounting plate 3 is arranged on the first sliding frame 2; a lower mold mounting plate 4 is arranged on the frame 1; a vulcanization bladder 5 is arranged on the lower mold mounting plate 4; an upper mold ring 6 is arranged on the upper mold mounting plate 3, and the upper mold ring 6 has an upper mold vulcanization surface; a lower mold ring 7 is arranged on the lower mold mounting plate 4, and the lower mold ring 7 has a lower mold vulcanization surface; after the first sliding frame 2 slides vertically downward, the upper mold ring 6 approaches the lower mold ring 7; the upper mold mounting plate 3, the lower mold mounting plate 4, the upper mold vulcanization surface, the lower mold vulcanization surface and the vulcanization bladder 5 together form a vulcanization space, and the vulcanization space is used to vulcanize tires.
[0056] In this embodiment, in order to solve the problem that the disassembly and installation process of the upper and lower molds of the capsule vulcanizer is complicated and requires a lot of manpower when switching products, the frame 1 is made of an integrated casting process to ensure that it always remains stable during long-term high-intensity production operations. Adjustable anchor bolts are provided at the bottom of the frame 1 to facilitate horizontal calibration under different ground conditions. A high-precision linear slide rail and slider combination is used between the first sliding frame 2 and the frame 1. The upper mold mounting plate 3 is positioned with the first sliding frame 2 by a locating pin and a centering device, and is fixed with a high-strength locking bolt to ensure that no displacement occurs during the vulcanization process. The lower mold mounting plate 4 is also fixed to a preset position at the bottom of the frame 1 by a centering device and a locking bolt. The vulcanization capsule 5 is made of a special rubber material that is resistant to high temperature and highly elastic, and is installed in the groove of the lower mold mounting plate 4 to ensure its stability during the vulcanization process.
[0057] When a tire is to be vulcanized, the green tire is placed inside the lower die ring 7. The operator simply enters the corresponding command into the central control system, and the sliding drive mechanism drives the first carriage 2 downward vertically at a constant speed, causing the upper die ring 6 to steadily approach the lower die ring 7. When the two are sufficiently close, the upper die mounting plate 3, the lower die mounting plate 4, the upper die curing surface, the lower die curing surface, and the curing bladder 5 together form a sealed curing chamber. The curing process is then initiated, and the tire curing operation begins.
[0058] The advantage is that it simplifies the disassembly and installation processes of the upper and lower molds. When switching products, operators no longer need to use cumbersome tools to remove and tighten bolts; they simply remove the upper and lower mold rings 6 and 7, significantly shortening mold switching time and reducing labor. Furthermore, this precise structural design ensures consistent and accurate mold installation every time, greatly improving the sealing and stability of the vulcanization chamber.
[0059] Furthermore, the lower mold mounting plate 4 has a plurality of slide grooves 401, which are evenly spaced around the axis of the lower mold mounting plate 4. The lower mold ring 7 has positioning holes 701, which are evenly spaced along the axis of the lower mold ring 7. It also includes a positioning rod 8, which is slidably set in the slide groove 401 and extends out of the slide groove 401; after the plurality of positioning rods 8 enter the plurality of positioning holes 701, the axis of the lower mold ring 7 coincides with the axis of the lower mold mounting plate 4.
[0060] In this embodiment, the surface of the lower die mounting plate 4 is provided with countersunk grooves 401, and these countersunk grooves 401 are radially distributed at equal intervals around the axis of the lower die mounting plate 4. The positioning rod 8 is a T-shaped rod, and its T-shaped head is adapted to the countersunk grooves 401. When the lower die ring 7 needs to be replaced, the worker first removes the lower die ring 7 that needs to be replaced. The new model of the lower die ring 7 is then hoisted above the lower die mounting plate 4 so that the positioning rod 8 corresponds to the positioning hole 701, and then the lower die ring 7 is lowered and the T-shaped rod is inserted into the positioning hole 701. As the lower die ring 7 continues to descend, until all the T-shaped rods accurately enter the corresponding positioning holes 701, the lower die ring 7 coincides with the axis of the lower die mounting plate 4.
[0061] The advantage is that, with the help of positioning rods 8 and positioning holes 701, ordinary workers can quickly complete the installation of lower die ring 7 when switching between product models, eliminating the need for complex measurements and adjustments. The high-precision fit of positioning rods 8 and positioning holes 701 ensures consistent and accurate installation of lower die ring 7 for different models, and also ensures more uniform force on the mold during tire vulcanization.
[0062] Furthermore, it also includes a robotic arm 9, which is arranged on the frame 1; a clamp 10 is slidably arranged at the end of the robotic arm 9, and is used to remove the vulcanized tire from the vulcanizing bladder 5.
[0063] In this embodiment, the robotic arm 9 is mounted on a side of the frame 1 via a base. Each joint of the robotic arm 9 is equipped with high-precision rotating shafts and transmission devices, enabling flexible movement with multiple degrees of freedom. A horizontal slide rail is provided at its end, to which the clamp 10 is connected. After the tire is vulcanized, the robotic arm 9, according to pre-programmed instructions, first adjusts the angle and moves the clamp 10 to the front of the vulcanization chamber. The clamp 10 then slides forward along the slide rail at the end of the robotic arm 9 until it reaches the appropriate gripping position to remove the vulcanized tire.
[0064] The advantage is that the coordinated operation of the robot arm 9 and the clamp 10 greatly improves the efficiency and quality of the tire retrieving process after vulcanization. The robot arm 9's flexible multi-degree-of-freedom motion and pre-programmed control enable it to quickly and accurately locate the vulcanized tire. Compared to manual operation, this greatly shortens the retrieving time and significantly improves production efficiency.
[0065] Furthermore, the lower mold ring 7 includes a positioning section 702, and several positioning holes 701 are all located on the positioning section 702, and the positioning section 702 has a first vulcanized surface 7021; the first swinging section 703 is hingedly set at one end of the positioning section 702, and the first swinging section 703 has a second vulcanized surface 7031; the second swinging section 704 is hingedly set at the other end of the positioning section 702, and the second swinging section 704 has a third vulcanized surface 7041; after the first swinging section 703 and the second swinging section 704 swing and approach, the first vulcanized surface 7021, the second vulcanized surface 7031 and the third vulcanized surface 7041 enclose to form the vulcanized surface of the lower mold.
[0066] In this embodiment, the positioning section 702 of the lower die ring 7 is provided with hinged seats at each end, while the first swinging section 703 and the second swinging section 704 are provided with hinged shafts at one end. Inserting the hinged shafts into the hinged seats completes the hinged installation of the first and second swinging sections 703, 704 and the positioning section 702 at both ends. The positioning section 702 is circumferentially provided with multiple positioning holes 701, which mate with the positioning components on the lower die mounting plate 4 to ensure the precise installation of the lower die ring 7 on the lower die mounting plate 4. The central region of the positioning section 702 is where the first curing surface 7021 is located.
[0067] The first swing section 703 and the second swing section 704 are each provided with a second vulcanized surface 7031 and a third vulcanized surface 7041 on their inner sides. When the tire is vulcanized and the clamp 10 is required for gripping, an external drive mechanism (e.g., a motor-driven connecting rod assembly) is activated. This drive mechanism causes the first and second swing sections 703, 704 to swing about their respective hinge points, away from the center of the positioning section 702. As the swing amplitude increases, a larger space is created between the first and second swing sections 703, 704, and the positioning section 702, exposing a larger area of the finished tire. At this point, the clamp 10, located above, can descend smoothly, unimpeded, and reach the appropriate location for gripping the tire.
[0068] The advantage is that the swingable structure of the lower die ring 7 also improves the convenience of the clamp 10 in gripping the vulcanized tire. With conventional mold structures, the space around the tire is limited after vulcanization, which can easily hinder gripping by the clamp 10, making operation difficult and inefficient. However, the outward swinging of the first and second swinging sections 703, 704 creates a wide operating space for the clamp 10, exposing a large area of the tire and significantly improving gripping accuracy and efficiency.
[0069] Furthermore, both ends of the positioning section 702 have sealing grooves 7022, and the first swing section 703 and the second swing section 704 have sealing protrusions 7032 near one end of the positioning section 702; after the lower mold vulcanization surface is formed, the two sealing protrusions 7032 are respectively located in the two sealing grooves 7022.
[0070] In this embodiment, as the first swinging section 703 and the second swinging section 704 swing toward the center of the positioning section 702 under the action of an external drive mechanism, preparing to form the lower mold vulcanization surface, the sealing protrusion 7032 gradually approaches the sealing groove 7022 along with the swinging section. As the swinging section reaches its final position, the sealing protrusion 7032 slowly and precisely embeds into the sealing groove 7022. With the swinging section fully in place, the two sealing protrusions 7032 are tightly located in the two sealing grooves 7022, forming an effective sealing barrier. During the tire vulcanization process, the high-temperature, high-pressure gas in the vulcanization chamber cannot escape from the connection between the positioning section 702 and the swinging section, ensuring the stability of the vulcanization environment.
[0071] Furthermore, it also includes a first telescopic member 11, and there are two first telescopic members 11. The two first telescopic members 11 are hingedly arranged on the lower mold mounting plate 4. The two first telescopic members 11 are hingedly connected to the first swing segment 703 and the second swing segment 704 respectively. After the two first telescopic members 11 are extended, the first swing segment 703 and the second swing segment 704 swing to form the vulcanization surface of the lower mold.
[0072] In this embodiment, the lower mold mounting plate 4 is provided with two hinged seats, located at positions corresponding to the first swing section 703 and the second swing section 704. The first telescopic member 11 utilizes a hydraulic telescopic rod, one end of which is connected to the hinged seat on the lower mold mounting plate 4 via a hinged joint. This allows the first telescopic member 11 to flexibly change its angle during movement to adapt to different operating conditions. The first telescopic member 11 also utilizes a hinged joint, articulating to predetermined hinge points on the first and second swing sections 703, 704.
[0073] When the vulcanized surface of the lower mold needs to be formed, the vulcanizer control system gradually extends the piston rod of the first telescopic member 11 of the hydraulic system. Since both ends of the first telescopic member 11 are connected in a hinged manner, during its extension, it will push the first swing segment 703 and the second swing segment 704 to swing in a circle around their hinge points with the positioning segment 702. During the swinging process, the first swing segment 703 and the second swing segment 704 gradually approach the center of the positioning segment 702, while driving their respective vulcanized surfaces to move accordingly. When the first telescopic member 11 is extended to a predetermined length, the first swing segment 703 and the second swing segment 704 just swing to the appropriate position. At this time, the first vulcanized surface 7021, the second vulcanized surface 7031 and the third vulcanized surface 7041 enclose and form a complete vulcanized surface of the lower mold.
[0074] After the tire is vulcanized, when the lower die ring 7 needs to be opened to remove the tire, the hydraulic system operates in reverse to pump out the oil in the cylinder, and the piston rod of the first telescopic member 11 retracts. The first telescopic member 11 drives the first swing section 703 and the second swing section 704 to swing in opposite directions, thereby opening the lower die ring 7 and facilitating tire removal.
[0075] Furthermore, the clamp 10 includes a mounting frame 1001, which is slidably set at the end of the robotic arm 9; there are two clamping jaws 1002, and the two clamping jaws 1002 are swingably set on the mounting frame 1001; the support plate 1003 is set on the clamping jaws 1002, and after the clamping jaws 1002 abut against the tire, the support plate 1003 is located between the tire and the lower mold mounting plate 4, and is used to support the tire.
[0076] In this embodiment, a sliding sleeve is provided at the end of the robotic arm 9, and the mounting frame 1001 is slidably connected to the sleeve via a slide rod. Two mounting shafts are symmetrically provided on either side of the mounting frame 1001. The clamping jaws 1002 are hingedly connected to the mounting frame 1001 via these two mounting shafts, allowing the clamping jaws 1002 to swing about the mounting shafts. A support plate 1003 is secured to the clamping jaws 1002 on the inner lower side of the clamping jaws 1002 via welding or bolts.
[0077] After the tire is vulcanized, the robotic arm 9 moves the clamp 10 to directly above the tire according to a pre-programmed path. At this point, the mounting bracket 1001 slides forward along the linear guide rail at the end of the robotic arm 9 and adjusts to the appropriate gripping position. Next, the drive motor is activated, driving the jaws 1002 to open outward with the mounting axis as the axis via a belt or gear transmission. After opening to a certain angle, the robotic arm 9 drives the clamp 10 as a whole downward. When the jaws 1002 contact the outer edge of the tire, the drive motor reverses, causing the jaws 1002 to close inward. As the jaws 1002 close, the support plate 1003, fixedly connected to the jaws 1002, moves synchronously between the tire and the lower mold mounting plate 4. Once the jaws 1002 firmly grasp the tire, the support plate 1003 supports the bottom of the tire, ensuring that the tire remains stable during the gripping process. The robotic arm 9 then transports the gripped tire to the designated unloading area.
[0078] The advantage is that while the gripper 1002 is grabbing the tire, the support plate 1003 can automatically move to the bottom of the tire to provide support. This all-round support method allows the tire to remain stable during the grabbing and transportation process, effectively preventing the tire from falling due to unstable center of gravity or uneven force.
[0079] Furthermore, the frame 1 has a clearance hole 101 and also includes a lifting and telescopic part 12, which is arranged on the frame 1 and connected to the first sliding frame 2; the mold closing telescopic part 13 is arranged on the first sliding frame 2 and the sliding plate 14 is slidably arranged on the frame 1, and the sliding plate 14 is used to close or open the clearance hole 101 after sliding; after the lifting and telescopic part 12 contracts, the mold closing telescopic part 13 extends from the clearance hole 101; after the lifting and telescopic part 12 extends, the mold closing telescopic part 13 withdraws from the clearance hole 101; the sliding plate 14 slides to close the clearance hole 101; the mold closing telescopic part 13 extends, and the mold closing telescopic part 13 contacts the sliding plate 14, which is used to press the upper mold ring 6 onto the lower mold ring 7 to form a vulcanization space.
[0080] In this embodiment, a clearance hole 101 is machined in the top of the frame 1. The lifting and telescopic member 12 is a hydraulic telescopic cylinder installed on both sides of the top of the frame 1. The top of its piston rod is connected to the top of the first slide 2, and can adapt to the movement trajectory of the first slide 2 during the extension and retraction process. The mold closing telescopic member 13 is also a hydraulic telescopic cylinder installed in the center of the top of the first slide 2, with the piston rod facing upward.
[0081] Sliding plates 14 are equipped with sliders on either side that mate with the guide rails of frame 1, allowing them to slide smoothly along the horizontal guide rails of frame 1. To prepare for startup of the vulcanizer, the control system extends the piston rod of the telescopic lifting member 12, causing the first carriage 2 to rapidly descend vertically. This causes the piston rod of the telescopic clamping member 13 to retract from the clearance hole 101. When the first carriage 2 descends to a predetermined idle travel position, the telescopic lifting member 12 stops, and the control system simultaneously causes the sliding plates 14 to slide along the guide rails, closing the clearance hole 101.
[0082] Subsequently, the mold clamping telescopic member 13 begins to operate. The piston rod extends, and its upper end contacts and applies pressure on the sliding plate 14, pushing the first carriage 2 further downward, gradually bringing the upper die ring 6 closer to the lower die ring 7 until they are tightly pressed together, forming a vulcanization space. After the tire is vulcanized, the entire process is reversed: the mold clamping telescopic member 13 retracts, the sliding plate 14 opens the clearance hole 101, and the lifting telescopic member 12 shortens, driving the first carriage 2 to rise and reset.
[0083] The advantage is that the telescopic lifting member 12, the telescopic mold closing member 13, and the sliding plate 14 work in tandem to achieve efficient and precise control of mold closing. The telescopic lifting member 12 quickly extends, driving the first slide frame 2 to complete most of its descending stroke in a short period of time, significantly shortening the initial preparation time for mold closing and greatly improving production efficiency compared to traditional mold closing methods.
[0084] The mold clamping telescopic member 13 begins operating after the sliding plate 14 closes the clearance hole 101. It precisely controls the pressing force between the upper and lower mold rings 6 and 7, ensuring a well-sealed and stable vulcanization chamber. This precise pressure control ensures uniform heat and pressure distribution during the vulcanization process, effectively improving vulcanization quality and reducing defective product rates.
[0085] The sliding plate 14 closes the clearance hole 101, providing a stable support point for the mold closing telescopic member 13, making the mold closing process more stable and reliable. This structural design makes the overall layout of the vulcanizer more compact and reasonable, and enhances the collaborative working ability between various components.
[0086] Furthermore, the lower mold mounting plate 4, the lower mold ring 7 and the vulcanization bladder 5 form a first vulcanization part; the upper mold mounting plate 3 and the upper mold ring 6 form a second vulcanization part. The first vulcanization part and the second vulcanization part are both present in a certain number and further include a second sliding frame 17. The second sliding frame 17 is vertically slidably arranged on the frame body 1 and is located below the first sliding frame 2. The first vulcanization part is arranged on the frame body 1 and / or the second sliding frame 17; the second vulcanization part is arranged on the second sliding frame 17 and / or the first sliding frame 2. The first vulcanization part and the second vulcanization part are pressed together to form a vulcanization space.
[0087] In this embodiment, vertical guide rails are provided on both sides of the frame body 1 , and the second sliding frame 17 is connected to the guide rails via matching sliders, and can slide vertically steadily and smoothly in the frame body 1 , and is located below the first sliding frame 2 .
[0088] The first curing section is composed of a lower mold mounting plate 4, a lower mold ring 7, and a curing bladder 5. Multiple first curing sections are strategically arranged to meet different production needs. Part of the first curing section is bolted to the bottom of the frame 1; the remainder is mounted on the upper surface of the second sliding frame 17, ensuring stability through a reliable connection. The second curing section, consisting of an upper mold mounting plate 3 and an upper mold ring 6, is arranged in a pattern that mirrors that of the first curing section. Part of the second curing section is tightly fixed to the bottom of the first sliding frame 2; the remainder is mounted above the second sliding frame 17, enabling coordinated operation with the corresponding first curing section below.
[0089] The advantage is that the design of multiple sets of first vulcanizing sections and second vulcanizing sections and double sliding frames can vulcanize multiple tires at the same time, greatly improving the output per unit time.
[0090] Furthermore, it also includes a connecting rod 18, which is a number of connecting rods 18. One end of the connecting rod 18 is set on the second sliding frame 17, and the other end passes through the first sliding frame 2; the driving block 19 is set at the other end of the connecting rod 18. After the lifting and telescopic member 12 is contracted, the driving block 19 contacts the first sliding frame 2, driving the second sliding frame 17 to slide vertically upward.
[0091] In this embodiment, several mounting blocks are evenly distributed across the top of the second carriage 17. One end of a connecting rod 18 is securely fastened to these mounting blocks by bolts or welding. The connecting rod 18 is long enough to smoothly penetrate the first carriage 2. Through holes are machined on the first carriage 2 at locations corresponding to the connecting rods 18, through which the connecting rods 18 pass. A driving block 19 is mounted on the other end of the connecting rod 18. The driving block 19 is slightly larger than the through holes in the first carriage 2 and is designed to facilitate contact with the first carriage 2 and effectively transmit power, such as a square or round shape.
[0092] When the lifting telescopic member 12 of the vulcanizer contracts, the first sliding frame 2 begins to slide vertically upward. As the first sliding frame 2 rises, the driving block 19 gradually approaches the first sliding frame 2. When the first sliding frame 2 rises to a certain position, the driving block 19 contacts the bottom surface of the first sliding frame 2. Due to the upward pulling force generated by the continuous contraction of the lifting telescopic member 12, the driving block 19 transfers this force to the first sliding frame 2 after contacting the first sliding frame 2, and at the same time drives the second sliding frame 17 to slide vertically upward. In this process, the movement speed and stroke of the first sliding frame 2 and the second sliding frame 17 are coordinated through precise mechanical design and control system to ensure that the movement of the two is synchronized and stable.
[0093] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
