Description

Technical Field

[0001] This invention relates to the field of tire vulcanization technology, specifically to a tire mold tooling and a tire mold assembly / disassembly method. Background Technology

[0002] Tire vulcanizing machines work in conjunction with tire molds to complete the tire vulcanization process. The tire mold includes a cavity assembly and a mold shell assembly. The cavity assembly forms the cavity, shaping the tire blank; the mold shell assembly drives the cavity assembly to open and close the mold. Currently, tire factories assemble the cavity and mold shell assemblies piece by piece, installing the tread blocks and sliders individually. When connecting the upper side plate and the upper cover, the sliders need to be removed from the upper cover, connected to the upper side plate, and then reassembled onto the upper cover. When storing the mold, the tread blocks and side plates are stored separately; therefore, the cavity assembly requires significant storage space and the assembly process is cumbersome.

[0003] To address the aforementioned problems, designing a tooling for tire molds to enable rapid assembly and disassembly of tire molds, and to store the molds as a whole, has become an urgent issue to be resolved. Summary of the Invention

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] On one hand, the present invention provides a tire mold tooling, including a quick-release ring, the quick-release ring including a ring body, on which a first quick-connect component is distributed for engaging with the end face of the tread block of the tire mold to radially limit the tread block;

[0007] The first quick-connect assembly includes a switch cam, a locking pin assembly, and a second elastic element; the locking pin assembly includes a bushing, a locking pin, and a first elastic element; the bushing has a floating cavity, one end of the locking pin extends into the floating cavity, the first elastic element is located in the floating cavity, and an elastic force is applied to the locking pin, causing the locking pin to tend to extend outward from the bushing;

[0008] The ring body is provided with a first mounting hole, and the bushing is slidably disposed in the first mounting hole. The second elastic element is disposed between the bushing and the inner wall of the first mounting hole, and an elastic force is applied to the bushing to drive the bushing away from the pattern block. A rotating shaft is rotatably mounted in the first mounting hole, and the switch cam is located in the first mounting hole and fixed on the rotating shaft. Controlling the rotating shaft to drive the switch cam to rotate causes the bushing to move up and down to enter the connected state or the open state.

[0009] The tire mold tooling described above also includes a tensioning element for connecting the upper and lower side plates of the tire mold.

[0010] And / or, the first quick-connect assembly further includes a limiting pin, the first mounting hole communicates with an expansion slot, the expansion slot is located on the rotation path of the switch cam, and the limiting pin is disposed on the slot wall of the expansion slot to limit the open state of the switch cam;

[0011] And / or, one end of the rotating shaft extends outward from the radial outer surface of the ring body;

[0012] And / or, the ring body is circular, and a plurality of the first quick-connect components are spaced apart and evenly distributed in the circumferential direction of the ring body.

[0013] In the aforementioned tire mold tooling, two quick-release rings are included, namely a first quick-release ring and a second quick-release ring, which respectively mate with the upper end face and the lower end face of the tread block.

[0014] In the above-mentioned tire mold tooling, the first quick-release ring includes a first ring body, and the first ring body is further provided with a second quick-connect assembly for connecting the first ring body to the upper side plate.

[0015] The second quick-connect assembly includes a third elastic element, a first retaining bead, and a first locking post; the first ring body is provided with a second mounting hole, the first locking post is fixedly installed in the second mounting hole and extends out of the second mounting hole at its upper end, and a radially extending third mounting hole is provided at the part of the first locking post that extends out of the second mounting hole, the third elastic element is located in the third mounting hole, the first retaining bead is located at the end of the third elastic element and partially extends out of the third mounting hole.

[0016] In the aforementioned tire mold tooling, an operating table is also included to assist the first quick-release ring in disengaging from the upper side plate; the operating table includes a support platform and a third quick-connect assembly;

[0017] A sliding groove is provided on the support surface of the support platform, and the sliding groove is connected to an operating hole;

[0018] The third quick-connect assembly includes a fourth elastic element, a push block, and a hook; the lower end of the hook is slidably disposed in the groove, the fourth elastic element is located in the groove and applies radial elastic force to the hook to maintain the hook engaged with the disassembly hole of the first ring; the push block is slidably disposed in the operating hole and can apply a pushing force to the hook to release the hook from the disassembly hole.

[0019] In the aforementioned tire mold tooling, a second positioning pin is fixed on the support surface of the support platform for positioning in conjunction with the third positioning hole of the first ring body.

[0020] In the aforementioned tire mold tooling, the second quick-release ring includes a second ring body, on which a first positioning pin is provided for positioning in conjunction with the lower side plate.

[0021] On the other hand, the present invention provides a tire mold assembly and disassembly method for disassembling and assembling the cavity assembly and the mold shell assembly of the tire mold. The cavity assembly includes multiple tread blocks, an upper side plate and a lower side plate. The mold shell assembly has a mold shell base, a guide ring, a slider and an upper cover. At least one end of the tread block is provided with a first snap-fit ​​hole and a guide groove on its end face. The guide groove is located radially inside the first snap-fit ​​hole and the bottom of the groove is an inwardly downward inclined surface.

[0022] The tire mold disassembly operation uses the tire mold tooling described above, and the following steps are performed in sequence:

[0023] S21. Place the quick-release ring on the lower side plate and / or the upper side plate, and the first quick-connect assembly is in the connected state.

[0024] Remove the connecting screws between the patterned block and the slider;

[0025] S22. Control the mold shell assembly to descend and close the mold. During the mold closing process, the locking pin contacts the guide groove and slides relative to it until the locking pin enters the first locking hole, completing the quick-release ring and the patterned block locking.

[0026] Remove the screws connecting the top cover and the top side plate;

[0027] S23. Control the mold shell assembly to rise and open the mold, with the upper side plate and the patterned block remaining on the lower side plate.

[0028] In the above-mentioned tire mold assembly and disassembly method, after the tire mold is disassembled, the upper side plate and the lower side plate are tightened using a tensioning element to connect the cavity assembly into a whole.

[0029] In the above-mentioned tire mold assembly and disassembly method, the assembly operation of using the tire mold tooling to install the cavity assembly to the mold shell assembly is also included.

[0030] Before assembly, the first quick-connect component of the quick-release ring is in a connected state; the assembly operation includes performing the following steps in sequence:

[0031] S11. Place the cavity assembly as a whole on the mold base, and then connect the lower side plate to the mold base;

[0032] S12. Adjust the first quick-connect component of the quick-release ring to the open state;

[0033] S13. Control the guide ring, the slider and the upper cover to fall until the upper cover is in contact with the upper end surface of the upper side plate, and then connect the upper side plate and the upper cover.

[0034] S14. Control the guide ring to rise, and fix the slider and the patterned block in place;

[0035] S15. Remove the quick-release ring to complete the assembly.

[0036] The beneficial effects of this invention are as follows:

[0037] The quick-release ring of the tire mold tooling can limit the ring-shaped tread blocks, allowing the tread blocks to be stored together with the upper and lower side plates located on their upper and lower sides; especially when used with the tensioning element, the overall structure of the cavity assembly is stable and easy to pick up and put down; combined with the disassembly and assembly of the tire mold, the disassembly and assembly efficiency is greatly improved, reducing the time for mold installation and disassembly.

[0038] The tire mold tooling has a simple overall structure, is easy to manufacture, and has low operating costs.

[0039] The locking pin assembly of the first quick-connect component can not only enter the connected or open state with the cooperation of the switch cam and the second elastic element, but also retract into the floating cavity when the tire mold is assembled or disassembled, so that the first quick-release ring and the second quick-release ring can automatically connect with the tread block during the tire mold closing process; together with the second quick-connect component and the operating table, the assembly and disassembly efficiency of the tire mold is greatly improved.

[0040] The quick-release ring is circular, with multiple first quick-connect components spaced apart and evenly distributed around its circumference to limit the position of each patterned block. When the first and second quick-release rings are used together to limit the two end faces of the patterned block, the overall storage and transfer state of the patterned block, upper side plate, and lower side plate becomes more stable.

[0063] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0064] like Figure 1 As shown, the cavity assembly 100 includes multiple tread blocks 110, an upper side plate 120, and a lower side plate 130. When the cavity assembly 100 is vulcanized, that is, in the use state, the multiple tread blocks 110 are distributed in a ring shape, corresponding to the formation of the tire tread; the upper side plate 120 and the lower side plate 130 are located at the upper and lower ends of the tread blocks 110, respectively, corresponding to the formation of the tire sidewall.

[0065] Please refer to Figures 1-15 The diagram illustrates a tire mold tooling, including a quick-release ring. The quick-release ring includes a ring body, on which first quick-connect components 230 are distributed circumferentially. The ring body can be placed on the upper or lower end face of the tread blocks 110. The first quick-connect components 230 are used to achieve radial positioning of each tread block 110. Since the circumferential positioning of the circumferentially distributed tread blocks 110 is already formed between each other, the relative positions of multiple circumferentially distributed tread blocks 110 can be defined by using the quick-release ring.

[0066] Preferably, the tire mold tooling further includes a tensioning element 400, which is used to connect the upper side plate 120 and the lower side plate 130; such as Figure 1As shown, the upper side plate 120 and the lower side plate 130 are respectively located at the upper and lower ends of the clamping patterned block 110. The upper side plate 120 is provided with a through hole for the tensioning element 400 to pass through. The tensioning element 400 passes through the upper side plate 120 from top to bottom and is detachably connected to the threaded hole of the lower side plate 130. The patterned block 110, the upper side plate 120 and the lower side plate 130 are all fixed together. The complete set of cavity components 100 is stored and disassembled in a unified manner. The overall structure is stable, convenient for storage and transfer during disassembly, and easy to operate.

[0067] Each tire mold tooling can have one quick-release ring. In this case, the quick-release ring can form a limit at the lower end face of the tread block 110, or it can form a limit at the upper end face of the tread block 110. The optimal choice is that the tire mold tooling includes two quick-release rings, that is, the tire mold tooling includes a first quick-release ring 200 and a second quick-release ring 300. The first quick-release ring 200 and the second quick-release ring 300 are used in conjunction with the upper and lower end faces of the tread block 110, respectively. The effect is more stable and reliable than limiting only one end face of the tread block 110.

[0068] Specifically, the first quick-release ring 200 includes a first ring body 210, and the second quick-release ring 300 includes a second ring body 310. The first ring body 210 and the second ring body 310 serve as connecting carriers, and are provided with a plurality of first quick-connect components 230, for example, six. Both the first ring body 210 and the second ring body 310 are annular, and the plurality of first quick-connect components 230 are spaced apart in the circumferential direction of the first ring body 210 and the patterned block 110, preferably evenly distributed.

[0069] Figure 2-8 An example of the assembly structure of the first quick-connect component 230 and the first ring body 210 is shown. The assembly structure of the second ring body 310 and the first quick-connect component 230 can be referred to the first ring body 210.

[0070] like Figure 3-8 As shown, each first quick-connect assembly 230 includes a switch cam 231, a locking pin assembly, a second elastic element 232, and a limiting pin 237. By controlling the rotation of the switch cam 231, the locking pin assembly can be driven into the connected state or the open state. The limiting pin 237 limits the open state position of the switch cam 231.

[0071] The locking pin assembly includes a bushing 233, a locking pin 234, and a first elastic element 235. The bushing 233 has a floating cavity, which opens at one end facing the patterned block 110. One end of the locking pin 234 extends into the floating cavity for sliding engagement. A limiting structure is provided between the locking pin 234 and the bushing 233 to prevent the locking pin 234 from dislodging from the floating cavity. Simultaneously, the first elastic element 235 is provided within the floating cavity. The first elastic element 235 applies an elastic force to the locking pin 234 to push the locking pin 234 out of the bushing 233. The first elastic element 235 can be a spring or other elastic element, resulting in a simple structure and low operating cost.

[0072] The first ring body 210 is provided with a first mounting hole 213, which is open at least on the lower end face of the first ring body 210. Preferably, the first mounting hole 213 extends through both the upper and lower end faces of the first ring body 210 for easy processing. The bushing 233 is located inside the first mounting hole 213 with a clearance fit, allowing the two to slide up and down relative to each other. A second elastic element 232 is provided between the bushing 233 and the inner wall of the first mounting hole 213. The second elastic element 232 applies an elastic force to the bushing 233 to drive the bushing 233 to move away from the patterned block 110.

[0073] Specifically, the first mounting hole 213 has a limiting surface 214 at its end facing the patterned block 110; exemplaryly, the first mounting hole 213 is a stepped hole, with a smaller inner diameter at its end near the patterned block 110, and a limiting surface 214 forming at the shoulder facing away from the patterned block 110. The second elastic element 232 is disposed between the limiting surface 214 and the bushing 233. Optionally, the second elastic element 232 is a spring, with its two ends abutting against the limiting surface 214 and the bushing 233 respectively; the second elastic element 232 applies a pushing force to the bushing 233, pushing the bushing 233 away from the patterned block 110.

[0074] Alternatively, the second elastic element 232 is located on the opposite side of the bushing 233 and the patterned block 110, that is, the second elastic element 232 and the patterned block 110 are located on opposite sides of the bushing 233. In this case, unlike the aforementioned structural scheme in which the second elastic element 232 is located between the limiting surface 214 and the bushing 233, the second elastic element 232 applies an elastic tension to the bushing 233, pulling the bushing 233 away from the patterned block 110.

[0075] A rotating shaft 236 is rotatably mounted on the end of the first mounting hole 213 away from the patterned block 110. The rotating shaft 236 extends at least outward from the radial outer surface of the first ring body 210, facilitating operation and control of the rotation of the rotating shaft 236. The switch cam 231 is located inside the first mounting hole 213 and fixed on the rotating shaft 236, rotating under the drive of the rotating shaft 236. Simultaneously, the first mounting hole 213 is connected to an expansion groove 212, which is located on the rotation path of the switch cam 231. The inner contour of the expansion groove 212 is larger than the outer contour of the switch cam 231, providing sufficient space for the rotation of the switch cam 231. Preferably, a limiting pin 237 is provided on the groove wall of the expansion groove 212 to limit the swing amplitude of the switch cam 231, ensuring that the switch cam 231 remains inside the first ring body 210.

[0076] Figure 3 and Figure 4 The first quick-connect assembly 230 is shown in both the open and connected states. In the open state, the locking pin 234 of the first quick-connect assembly 230 is completely inside the first mounting hole 213. At this time, the switch cam 231 is basically horizontal, avoiding the path of the bushing 233 retracting. In the connected state, the switch cam 231 abuts against the bushing 233, pushing the locking pin 234 out of the first mounting hole 213.

[0077] Matching, such as Figure 8 As shown, a first snap-fit ​​hole 111 is provided on the end face of the patterned block 110. When the first quick-connect assembly 230 is in the connected state, the snap-fit ​​pin 234 can enter the first snap-fit ​​hole 111. Thus, when multiple patterned blocks 110 are distributed in a ring, the snap-fit ​​pin 234 cooperates with the first snap-fit ​​hole 111 to complete the radial limiting of the patterned block 110; the relative positions of the multiple patterned blocks 110 are also limited. When the first quick-connect assembly 230 is in the open state, the snap-fit ​​pin 234 retracts from the first snap-fit ​​hole 111 and no longer limits the patterned block 110.

[0078] Furthermore, such as Figure 2 , Figure 9-11 As shown, the first ring body 210 is also provided with a second quick-connect assembly 220 for connection with the upper side plate 120; the second ring body 310 is provided with a first positioning pin 320 for positioning in conjunction with the lower side plate 130. Two or more second quick-connect assemblies 220 can be distributed circumferentially on the first ring body 210, connecting the first ring body 210 to the upper side plate 120 while also defining their relative positions. Similarly, two or more first positioning pins 320 are provided circumferentially on the second ring body 310.

[0079] For details, please refer to Figure 10The second quick-connect assembly 220 includes a third elastic element 224, a first retaining bead 223, and a first locking post 221. The first ring body 210 is provided with a second mounting hole 211, which is open at least on the upper end face of the first ring body 210. Preferably, the second mounting hole 211 extends through the upper and lower end faces of the first ring body 210. The first locking post 221 is installed in the second mounting hole 211 and is preferably detachable for easy assembly and maintenance / replacement. The lower outer circumferential surface of the first locking post 221 is provided with a connecting thread to connect with the first ring body 210; the lower end surface of the first locking post 221 is provided with a hexagonal groove for assembly operations; the upper end of the first locking post 221 extends out of the second mounting hole 211, and the portion of the first locking post 221 extending out of the second mounting hole 211 is provided with a radially extending and penetrating third mounting hole 222, the third elastic element 224 is located in the third mounting hole 222, and the two first retaining beads 223 are located at both ends of the third elastic element 224, and partially extend out of the third mounting hole 222. The third elastic element 224 and the first retaining beads 223 are connected as a whole to prevent the first retaining beads 223 from falling off.

[0080] The upper side plate 120 is provided with a second snap-fit ​​hole 121. The second snap-fit ​​hole 121 is a stepped hole with a smaller inner diameter at the end near the first ring body 210. When the first locking pin 221 is inserted into the second snap-fit ​​hole 121, the two first locking beads 223 are engaged on the shoulder of the stepped hole, thus completing the snap-fit ​​between the upper side plate 120 and the first ring body 210.

[0081] Please refer to Figure 11 The second ring 310 has a first positioning hole 311 machined on it, and the first positioning pin 320 is fixedly installed in the first positioning hole 311 with its lower end extending out of the first positioning hole 311. The lower side plate 130 is provided with a second positioning hole 131. When the first positioning pin 320 is simultaneously located in the first positioning hole 311 and the second positioning hole 131, the second quick-release ring 300 is positioned with the lower side plate 130.

[0082] like Figure 12-15 The tire mold tooling also includes an operating table 500 that assists in disengaging the first quick-release ring 200 from the upper side plate 120, thereby disabling the connection of the second quick-connect assembly 220. The operating table 500 includes a support table 510 and a third quick-connect assembly. The third quick-connect assembly can cooperate with the first quick-release ring 200 to pull the first quick-release ring 200 down from the upper side plate 120, thereby separating the two.

[0083] like Figure 13As shown, the third quick-connect assembly includes a fourth elastic element 520, a push block 530, and a hook 540; the support platform 510 is provided with a slide groove 512 and an operating hole 511. The slide groove 512 is open on the support surface of the support platform 510, and the lower end of the hook 540 is located in the slide groove 512 for sliding engagement; the fourth elastic element 520 is also located in the slide groove 512 and applies radial elastic force to the hook 540; the push block 530 is slidably disposed in the operating hole 511 and can apply radial thrust to the hook 540.

[0084] Correspondingly, the first ring body 210 is provided with a disassembly hole 215 at the corresponding position of the hook 540. The disassembly hole 215 has an axial extension and a radial extension. In use, after the support surface of the support platform 510 contacts the first quick-release ring 200, the hook 540 enters the disassembly hole 215 to achieve engagement; then, when the support platform 510 descends relative to the upper side plate 120, it drives the first quick-release ring 200 away from the upper side plate 120. To separate the first quick-release ring 200 and the support platform 510, simply press and hold the push block 530 to release the engagement.

[0085] Furthermore, such as Figure 14 and Figure 15 As shown, a second positioning pin 550 is fixed on the support surface of the support platform 510; a third positioning hole 216 is provided at the corresponding position of the first ring body 210 and the second positioning pin 550; when the support platform 510 and the first ring body 210 are engaged, the second positioning pin 550 and the third positioning hole 216 are used for positioning.

[0086] Optionally, the support platform 510 is provided with two or more third quick-connect components and second positioning pins 550 in its circumferential direction. The multiple third quick-connect components apply force to the first ring body 210 to avoid jamming or deformation caused by uneven force. The multiple second positioning pins 550 cooperate to position the support platform 510 and the first ring body 210 to ensure that the hook 540 enters the disassembly hole 215 and engages.

[0087] Furthermore, annular grooves may be provided on the upper end face of the lower side plate 130 and the lower end face of the upper side plate 120 to provide radial coarse positioning of the second ring body 310 and the first ring body 210, as well as to provide installation space.

[0088] Before assembly, the cavity assembly 100 is in the following state: Figure 1 In the storage configuration shown, the first quick-release assembly 230 on the first quick-release ring 200 and / or the second quick-release ring 300 is in operation, and the inner sides of the upper side plate 120 and the lower side plate 130 are tightened using a tensioning element 400. The tensioning element 400 may be a screw or other type of connecting element, applying an axial force to the upper side plate 120 and the lower side plate 130 to define their relative positions.

[0089] like Figure 7 , Figure 9 , Figure 12 , Figure 14 As shown, the mold housing assembly 600 has a mold housing base 610, a guide ring 620, a slider 630, and a top cover 640; the assembly operation of the tire mold requires the cavity assembly 100 to be installed onto the mold housing assembly 600, including connecting the slider 630 to the tread block 110, connecting the upper side plate 120 and the top cover 640, and connecting the lower side plate 130 to the mold housing base 610.

[0090] The aforementioned tire mold tooling can assist in the assembly and disassembly of tire molds. The tire mold assembly and disassembly method includes assembly operations and disassembly operations.

[0091] The assembly operation includes performing the following steps in sequence:
