[0002] The center mechanism is also called a capsule operating mechanism, and is an important component of a shaping vulcanizing machine. The center mechanism is used to load the capsule into the tire blank before vulcanization, shape the tire, push the capsule out of the tire after vulcanization, and make the tire separate from the lower mold and the tire bead, and finally make the capsule exit from the outer tire.

[0003] The center mechanism generally comprises a center shaft and a cylinder assembly sleeved on the center shaft. An internal pressure water channel for supplying water in the capsule and a center shaft moving water channel for moving the center shaft up and down are arranged in the cylinder assembly.

Detailed Implementation

[0042] The present invention will be further described below with reference to the embodiments and accompanying drawings:

[0043] like Figures 1-29 As shown, a water supply and drainage system for the central mechanism of a vulcanizing machine is provided. The central mechanism mainly consists of a central shaft 1 and a cylinder assembly. The cylinder assembly is fitted on the outer side of the lower end of the central shaft. A lower ring assembly for fixing the capsule is provided near the upper end of the central shaft. The cylinder assembly is located below the lower ring assembly and can drive the lower ring to move relative to the central shaft. The lower ring assembly is a prior art technology, and its structure usually consists of two lower rings 4 arranged vertically and a lower clamping plate 24 arranged above the lower rings.

[0044] The cylinder assembly is provided with an internal pressure water channel for realizing water supply in the capsule and a central shaft moving water channel for realizing the up and down movement of the central shaft, and the cylinder assembly comprises a lower end cover 5, which is provided with a water inlet hole 5a and a backwater hole 5b for realizing the water inlet and outlet of the internal pressure water channel, and is further provided with a central shaft upward moving water inlet and outlet hole 5c and a central shaft downward moving water inlet and outlet hole 5d for realizing the water inlet and outlet of the central shaft moving water channel.

[0045] The water supply and drainage system comprises a rotating link 13, a rotating frame 14 and a rotating seat 15, and the rotating link 13 is hinged on the left and right sides of the lower end cover 5 through corresponding end cover flange shafts 16, and the other end of the rotating link 13 is hinged on the rotating frame 14, and the other end of the rotating frame 14 is hinged on the rotating seat 15 through corresponding rotating flange shafts 17, wherein the end cover flange shaft 16, the rotating link 13, the rotating frame 14, the rotating flange shaft 17 and the rotating seat 15 are all provided with water supply and drainage channels h for realizing the water inlet and outlet of each water hole, and the end cover flange shaft 16, the rotating link 13 and the rotating flange shaft 17 are all provided with two water supply and drainage channels h, and the rotating frame 14 and the rotating seat 15 are both provided with four water supply and drainage channels h. Through the arrangement of the rotating water supply and drainage assembly, the water inlet and outlet of the central structure is a hard pipe, so that the service life can be effectively improved and the replacement frequency can be reduced.

[0046] Since the lower end cover moves up and down with the cylinder body, in order to realize the function of the rotating water supply and drainage assembly, the structures of the end cover flange shaft 16 and the rotating flange shaft 17 are the same, as shown in Figures 5-8 , which both comprise a first flange plate j for connecting with corresponding parts and a flange rotating shaft k for realizing the hinge, and the water supply and drainage channels on the end cover flange shaft 16 and the rotating flange shaft 17 are arranged along the axis of the flange rotating shaft k.

[0047] As shown in Figures 9-10 , the rotating link 13 is arranged in an I-shaped structure, and the left and right sides of the upper and lower ends of the rotating link 13 are both arranged as link rotating sleeves 13a, and the middle part of the rotating link 13 is arranged as two water supply and drainage channels of the rotating link 13, and the link rotating sleeves 13a are both provided with link water supply and drainage holes 13b corresponding to each water supply and drainage channel.

[0048] As shown in Figures 11-12 , the rotating frame 14 is arranged in an I-shaped structure, the left and right sides of the upper end of the rotating frame 14 are arranged as rotating frame rotating shafts 14a which can be sleeved in the link rotating sleeves 13a, the left and right sides of the lower end of the rotating frame 14 and the left and right sides of the lower end cover 5 are both provided with second flange plates m which can be fixed with the first flange plates j, and the middle part of the rotating frame 14 is arranged as four water supply and drainage channels of the rotating frame 14.

[0050] like Figures 13-14 As shown, the rotating seat 15 includes a lower mounting base 15a. On both the left and right sides of the mounting base 15a, there are rotating seat sleeves 15c that can be fitted onto the flange rotating shaft k via connecting plates 15b extending upwards. On the rotating seat sleeves 15c, there are water supply and drainage pipes 15d for water supply and drainage of the corresponding water supply and drainage channels. In addition, there are rotating seat water supply and drainage holes 15e in the rotating seat sleeves 15c corresponding to each water supply and drainage pipe. On the left and right sides of the two connecting rod water supply and drainage holes 13b and the left and right sides of the two rotating seat water supply and drainage holes 15e, there are sealing ring positioning grooves i for sealing the water supply and drainage between the rotating connecting rod 13 and the corresponding parts.

On the left and right sides of the lower end cover, there are also guide post connecting holes 5e located on the outside of the cylinder assembly. The guide post connecting holes 5e are connected to the water inlet or water return holes on the corresponding sides. The water inlet or water return holes can also be located directly below the cylinder assembly. This arrangement allows the lower end cover to be used for both central mechanisms with internal pressure water channels located inside the cylinder assembly and central mechanisms with internal pressure water channels located outside the cylinder assembly.

[0052] In this embodiment, the cylinder assembly also includes an upper end cover 2 and a cylinder body 3 arranged sequentially from top to bottom. A lower end cover 5 is located at the lower end of the cylinder body 3 and below the central axis 1. The internal pressure water inlet and outlet channels include an internal pressure water inlet channel c and an internal pressure water return channel d within the cylinder body 3 and the upper end cover 2. Multiple internal pressure water outlet holes a communicating with the internal pressure water inlet channels are provided on the upper end cover. An internal pressure water return groove b communicating with the internal pressure water return channel is also provided on the upper end cover, with the internal pressure water outlet holes and the internal pressure water return groove located on both sides of the upper end cover. During vulcanization, hot pressurized water enters through the water inlet holes of the lower end cover, then flows along the internal pressure water inlet channels to the upper end cover, passes through the multiple internal pressure water outlet holes a, enters the capsule, then returns along the internal pressure water return groove to the internal pressure water return channel, and finally flows out through the water return holes. The multiple internal pressure water outlet holes facilitate the outflow of hot pressurized water, while the rectangular structure of the internal pressure water return groove effectively facilitates water return.

[0053] In order to realize the installation between the cylinder assembly and the lower ring, between the cylinder assemblies, the upper end cover 2 is vertically provided with an upper end cover fixing through hole 2a capable of fixing the upper end cover 2 on the upper end of the cylinder body 3, and the upper end cover fixing through hole is provided as a counterbore, the upper end of the cylinder body 3 is vertically provided with an upper end cover fixing hole 3b at a position corresponding to the upper end cover fixing through hole 2a, the upper end cover 2 is also vertically provided with a lower ring fixing through hole 2b for fixing the lower ring 4, and the upper end of the cylinder body 3 is vertically provided with a lower ring fixing through hole 3c at a position corresponding to the lower ring fixing through hole 2b, in order to facilitate the fixing of the lower ring, the cylinder body 3 is provided with a clearance slot 3d below the lower ring fixing through hole 3c. The lower end cover is provided with a lower end cover fixing hole, the lower end of the cylinder body is provided with a lower end cover fixing through hole, and the cylinder body is also provided with a clearance slot above the lower end cover fixing through hole.

[0054] The upper end cover and the cylinder body can be fixed by screwing a bolt from top to bottom through the upper end cover fixing through hole and then tightening it in the upper end cover fixing hole. The lower ring can be fixed by screwing a bolt from bottom to top through the lower ring fixing through hole, the lower ring fixing through hole and then tightening it on the lower ring. The lower end cover and the cylinder body can be fixed by screwing a bolt from top to bottom through the lower end cover fixing through hole and then tightening it in the lower end cover fixing hole. Due to the provision of the clearance slot, the upper end of the cylinder body is an embedded flange structure, which not only facilitates installation, but also facilitates size reduction.

[0055] The central shaft moving water channel includes a central shaft downward moving water channel e and a central shaft upward moving water channel f, and a central shaft piston 1a is provided outwardly at the lower end of the central shaft 1, wherein the cavity in the cylinder body 3 above the central shaft piston 1a is a central shaft downward moving water cavity A, and the cavity in the cylinder body 3 below the central shaft piston 1a is a central shaft upward moving water cavity B, the central shaft downward moving water channel e is provided on the cylinder body 3 and the lower end cover 5 and communicates with the central shaft downward moving water cavity A, and the central shaft upward moving water channel f is also provided on the cylinder body 3 and the lower end cover 5 and communicates with the central shaft upward moving water cavity B. The central shaft upward moving water inlet and outlet hole 5c communicates with the central shaft upward moving water channel f, and the central shaft downward moving water inlet and outlet hole 5d communicates with the central shaft downward moving water channel e. When liquid is injected into the central shaft downward moving water cavity along the central shaft downward moving water channel through the central shaft downward moving water inlet and outlet hole, the central shaft will be pushed to move downward relative to the cylinder body, at this time the central shaft upward moving water cavity will be in a liquid discharge state. When liquid is injected into the central shaft upward moving water cavity along the central shaft upward moving water channel through the central shaft upward moving water inlet and outlet hole, the central shaft will be pushed to move upward relative to the cylinder body, at this time the central shaft downward moving water cavity will be in a liquid discharge state.

In order to realize the installation between the lower ring water cylinder and the cylinder body, a water cylinder end cover 7 is arranged between the cylinder body 3 and the lower ring water cylinder 6 at the upper end of the lower ring water cylinder 6, so that the water cylinder end cover 7 and the cylinder piston 3a form a cylinder down-moving water cavity E, and a cylinder down-moving water inlet and outlet hole 6c communicating with the cylinder down-moving water cavity E is arranged on the lower ring water cylinder 6. When liquid is injected into the cylinder down-moving water cavity through the cylinder down-moving water inlet and outlet hole, the cylinder body is pushed to move downward relative to the central shaft, at this time the cylinder up-moving water cavity appears a liquid discharge state. When liquid is injected into the cylinder up-moving water cavity through the cylinder up-moving water inlet and outlet hole, the cylinder body is pushed to move upward relative to the central shaft, at this time the cylinder down-moving water cavity appears a liquid discharge state.

[0057] In order to facilitate the fixation between the lower ring water cylinder and the water cylinder end cover, a circle of installation flanges g is arranged outward at the upper end of the water cylinder end cover 7 and the upper end of the lower ring water cylinder 6, and the installation flanges are arranged as the flanges for fixing the water cylinder end cover and the lower ring water cylinder. A sealing assembly is arranged between the cylinder piston 3a and the lower ring water cylinder 6, between the sealing protrusion 6a and the cylinder body 3, between the water cylinder end cover 7 and the cylinder body 3, between the water cylinder end cover 7 and the lower ring water cylinder 6, between the cylinder body 3 and the central shaft 1, and between the central shaft piston 1a and the cylinder body 3. A water channel sealing ring 8 is arranged on the water channel connected between the upper end cover 2 and the cylinder body 3 and on the water channel connected between the lower end cover 5 and the cylinder body 3.

[0061] To prevent the lower end cap from rotating, guide sleeves 6d are provided on both the left and right sides of the upper end of the lower ring water cylinder 6, extending downwards. A guide post 20 is installed in the guide post connection hole 5e, with the upper end of the guide post 20 extending into the guide sleeve 6d, and the guide post 20 can move up and down within the guide sleeve 6d. When the entire central mechanism is used to vulcanize larger tires, such as 6-inch or 8-inch tires, to ensure the flow rate and velocity of the hot pressurized water during vulcanization, the guide post can be replaced with an internal pressure pipe for the inlet and outlet of internal pressure circulating water.

[0062] To facilitate the measurement of the vertical movement of the central axis and thus the determination of the vertical height of the capsule, a sensor mounting hole 5f for mounting a displacement sensor is provided at the lower end of the lower end cover 5. Correspondingly, a detection block mounting hole 1b for mounting a detection block that can be detected by the displacement sensor is provided at the lower end of the central axis 1. A sensor cover 21 for covering the displacement sensor is provided below the lower end cover 5. To facilitate the installation between the sensor cover and the lower end cover, a fixing flange is provided at the lower end of the lower end cover 5 and the upper end of the sensor cover 21. A clamp 22 for fixing the lower end cover 5 and the sensor cover 21 is provided outside the two fixing flanges, and a clamp pressure plate 23 is provided outside the clamp 22.

[0063] Ideally, the guide sleeve, rotating connecting rod, rotating frame, and rotating seat outside the lower ring water cylinder should all be welded. Each channel should ideally be elliptical and located in the middle of the part. During machining, the through holes should be machined first, and then the ends welded, ensuring the airtightness of each channel. Figure 27 As shown, this application can be applied to the vulcanization of tires of other sizes after the upper end cap is replaced, and the upper end cap and the lower ring can also be fixed by a threaded connection.
