Description

Technical Field

[0001] This invention belongs to the field of rubber production technology, specifically a high-stability tire vulcanizing bladder production device and its production method. Background Technology

[0002] A vulcanizing bladder is a hollow, thin-walled rubber product used in tire vulcanizing machines. It is inserted into the inner cavity of the tire blank to be vulcanized, and then a heating medium is introduced to assist the vulcanizing machine in shaping and vulcanization. A tire vulcanizing bladder is an auxiliary material used in tire vulcanization. It is usually wrapped in the core of the bladder machine and softened and released under heating and pressure. The vulcanizing agent and accelerator inside are added to the rubber compound, thereby enabling the rubber material to complete the vulcanization reaction and improve the performance and quality of the tire. Sulfur bladders are often used to assist in tire production.

[0003] The production of tire vulcanizing bladders involves multiple processes. A tire vulcanizing bladder production unit is a machine used to produce tire vulcanizing bladders, mainly consisting of a sulfur feeding system, a rubber injection molding system, a molding system, a heating system, a cooling system, and a demolding system. The main processing steps are mixing and feeding materials, rubber extrusion and heating molding, and demolding and cooling of the rubber product. However, this type of equipment has high energy consumption in actual use. It requires a mixing device for mixing materials and a heating device for heating the rubber, both of which consume energy, resulting in high energy consumption. Therefore, it is crucial to reduce energy consumption while achieving rubber mixing and heating molding.

[0004] In the production process of rubber vulcanized bladders, after the rubber vulcanized bladders are heated and extruded, they usually need to be demolded. In the existing technology, cylinders or hydraulic cylinders are generally used to demold the tires. After demolding, air cooling and water cooling are required to cool the vulcanized bladders. This operation requires the installation of multiple sets of structures to achieve the demolding and cooling process, resulting in a relatively complex overall structure of the equipment, a large footprint, and unsuitability for small-scale processing. Summary of the Invention

[0005] The purpose of this invention is to provide a high-stability tire vulcanizing bladder production apparatus and production method to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-stability tire vulcanizing bladder production device, comprising a water storage tank, a first frame fixedly installed near the right end of the water storage tank, a mixing tank fixedly installed above the water storage tank on the inner side of the first frame, a second frame fixedly installed near the left end of the water storage tank, a demolding assembly fixedly installed above the water storage tank on the bottom end of the inner side of the second frame, a steam assembly fixedly installed at the right end of the mixing tank, a discharge port opened at the bottom end of the mixing tank, a forming cavity fixedly installed below the discharge port at the bottom end of the mixing tank, a forming mold provided at the bottom end of the forming cavity, transverse guide rails fixedly installed on both the front and rear sides of the top of the water storage tank, a water pump fixedly installed at the right end of the water storage tank, the output end of the water pump being connected to the water storage tank, a circulation pipe fixedly connected to the output end of the water pump, the other end of the circulation pipe being connected to the steam assembly, and a filling port fixedly connected to one side of the top of the mixing tank.

[0007] In actual use, first ensure the capacity of the water flow inside the storage tank and replenish it as needed. Then, select the appropriate raw materials according to the type of processing and inject them into the mixing tank through the inlet. At the same time, turn on the power supply of the device to complete the preparation.

[0008] Preferably, the molding die is located on the inner side of the molding cavity, and the top of the two second frames is provided with a mounting plate. Guide blocks are fixedly installed on both the front and rear sides of the bottom end of the mounting plate, and the guide blocks are movably engaged with the transverse guide rail.

[0009] Preferably, a longitudinal telescopic rod is fixedly installed at the top of the mounting plate, and the top of the longitudinal telescopic rod is fixedly connected to the bottom of the forming mold. A transverse telescopic rod is fixedly installed on both the front and rear sides of the left end of the mounting plate, and the other end of the transverse telescopic rod is connected to the side of the transverse guide rail.

[0010] When processing vulcanized capsules, the molding die must be kept inside the molding cavity, with the bottom of the molding die in contact with the bottom of the molding cavity to complete the sealing operation. When demolding is required after the vulcanized capsule is formed, the longitudinal telescopic rod is first shortened to lower the molding die and remove it from the molding cavity. Then, the transverse telescopic rod is shortened and, guided by the guide block and transverse guide rail, the molding die is moved to the left until it is directly below the demolding assembly, ready for subsequent demolding operations. After demolding, the molding die should return to the inside of the molding cavity under the combined action of the transverse and longitudinal telescopic rods, ready for the secondary vulcanized capsule forming operation.

[0011] Preferably, the steam assembly includes a steam tank, a heating rod is fixedly installed in the middle of the inner cavity of the steam tank, a water inlet is fixedly connected to the side of the steam tank near the bottom, the water inlet is connected to a circulation pipe, and a steam pipe is fixedly connected to the top of the steam tank.

[0012] Preferably, a power tank is fixedly installed at the middle of the top of the mixing tank, a main shaft is movably installed at the middle of the inner cavity of the power tank, an impeller located inside the power tank is fixedly sleeved on the outer side of the main shaft, and a stirring shaft located inside the mixing tank is fixedly connected to the bottom end of the main shaft through the bottom end of the power tank and the top of the mixing tank at equal angles.

[0013] Preferably, the left end of the power tank is fixedly connected to a first air supply pipe, the bottom end of the first air supply pipe is fixedly connected to a three-way valve, the right end of the three-way valve is fixedly connected to a second air supply pipe, the other end of the second air supply pipe is connected to the molding cavity, and the left end of the three-way valve is connected to the demolding assembly.

[0014] During the molding of the vulcanized capsule, water is first drawn from the reservoir by a water pump and injected into the steam tank through a circulation pipe. The water is then heated by a heating rod to generate steam, which is then discharged through a steam pipe and enters the power tank, driving the impeller to rotate. This, in turn, rotates the main shaft, ultimately causing the stirring shaft to move circumferentially. This mixes the raw materials in the mixing tank. The mixed materials are discharged through the discharge port and extruded between the molding cavity and the molding die. Meanwhile, the steam entering the power tank is discharged through the first gas supply pipe and introduced into the molding cavity through a three-way valve and a second gas supply pipe to heat the raw materials inside, completing the heating and extrusion molding. Some of the steam is discharged through the left end of the three-way valve.

[0015] By reusing the steam used for heating raw materials, the steam can be used to heat the raw materials at high temperature, and the steam's flowability can also be used as a power source to automatically mix and stir the raw materials. Both of these processes are powered by high-temperature steam, so the device does not need to be equipped with multiple power units. Only water heating is required to achieve simultaneous mixing and heating of raw materials, resulting in low energy consumption, significantly reducing resource consumption, and improving energy utilization.

[0016] Preferably, the demolding assembly includes a temporary storage tube, the top end of which is connected to the top end of the inner side of the second frame. An air inlet valve is fixedly connected to the right side of the temporary storage tube near the bottom end. The air inlet valve is connected to a three-way valve. A piston plate is movably sleeved inside the temporary storage tube. The piston plate moves up and down relative to the temporary storage tube. A piston rod is fixedly connected to the bottom end of the piston plate.

[0017] Preferably, the bottom end of the piston rod passes through the bottom end of the temporary storage tube and is fixedly installed with a vacuum suction cup. A return spring is movably sleeved on the outer side of the piston rod. The upper and lower ends of the return spring are respectively connected to the bottom end of the piston plate and the bottom end of the inner cavity of the temporary storage tube. The upper and lower ends of the left side of the temporary storage tube are respectively fixedly connected to a second exhaust valve and a first exhaust valve.

[0018] Preferably, the other end of the first and second exhaust valves is fixedly connected to a condenser box, the left end of the condenser box is fixedly connected to a drain pipe located above the water storage tank, and both the first and second exhaust valves are equipped with solenoid valves.

[0019] After the vulcanized capsule is formed, the molding die can be controlled to move below and contact the demolding assembly. When demolding is not required, high-temperature steam can enter the inlet valve through the three-way valve. At this time, the solenoid valve inside the first exhaust valve remains open, while the solenoid valve inside the second exhaust valve remains closed. The high-temperature steam can then be discharged through the first exhaust valve and enter the condenser. When demolding is required, the solenoid valve inside the first exhaust valve is closed, and the solenoid valve inside the second exhaust valve is opened. The steam then applies pressure to the piston plate, and the piston plate and piston... The rod moves upward, compressing the return spring. At this point, the vacuum suction cup is pre-activated to adhere to the vulcanizing capsule. The vacuum suction cup moves upward, causing the vulcanizing capsule to detach from the molding mold and complete the demolding process. When the piston plate moves above the second exhaust valve, the high-temperature steam can be discharged through the second exhaust valve and enter the interior of the condenser. After condensation, the steam entering the condenser can be discharged through the drain pipe and flow back into the water storage tank to complete the cycle. After demolding, the vacuum suction cup can be closed to allow the vulcanizing capsule to fall freely and enter the interior of the water storage tank to contact the cooling water and complete the cooling process.

[0020] By further utilizing high-temperature steam, the continuous input of high-temperature steam is used as pressure to act on the vulcanizing capsule, which can achieve automatic demolding of the vulcanizing capsule. The high-temperature steam can be condensed back into water for cooling the vulcanizing capsule. At the same time, the water is also heated during the cooling process of the vulcanizing capsule, thereby shortening the time for subsequent water heating and reducing energy consumption. Steam is used as the main energy source throughout the entire process, eliminating the need for multiple power mechanisms. In addition, the steam can be recycled, resulting in extremely high resource utilization. The process requires a small footprint and is suitable for batch processing.

[0021] A production method for a high-stability tire vulcanizing bladder production apparatus includes the following steps:

[0022] S1: First, fill the water tank with clean water and turn on the power of the water pump. Then, inject the raw materials into the mixing tank through the injection port for mixing. Place the molding mold on the inner side of the molding cavity to complete the preparation work.

[0023] S2: The raw materials injected through the injection port enter the mixing tank. At this time, the water pump is turned on to draw water from the water storage tank into the steam tank through the circulation pipe, and the heating rod is turned on to heat it. The steam generated by heating can be discharged through the steam pipe and enter the power tank, driving the impeller to rotate. At this time, the main shaft rotates accordingly and drives the stirring shaft to stir and complete the mixing of the raw materials.

[0024] S3: At the same time, steam can be discharged through the first gas supply pipe and enter the interior of the three-way valve. Some steam will be injected into the interior of the molding cavity through the second gas supply pipe. At this time, the uniformly mixed raw material can be discharged through the discharge port and act on the position between the molding cavity and the molding die. At this time, steam can enter the interior of the molding cavity to heat the raw material. Combined with the extrusion molding between the molding cavity and the molding die, the molding process of the vulcanized capsule is completed.

[0025] S4: After the vulcanized capsule is formed, the molding mold can be lowered by controlling the shortening of the longitudinal telescopic rod and the shortening of the transverse telescopic rod, which will move the molding mold to the left until it is below the demolding component. At this time, the longitudinal telescopic rod is extended until the vulcanized capsule at the top of the molding mold contacts the bottom of the demolding component.

[0026] S5: At this time, close the solenoid valve of the first exhaust valve and open the solenoid valve inside the second exhaust valve. At the same time, open the vacuum suction cup. The vacuum suction cup can then adhere to the vulcanizing capsule. The steam inside the three-way valve can be input into the storage tube through the air inlet valve and apply an upward thrust to the piston plate until the piston plate rises. This, in turn, drives the piston rod and the vacuum suction cup to rise, and finally drives the vulcanizing capsule to rise to complete demolding. Then, the molding mold returns to its initial working position, the vacuum suction cup is closed, and the sulfur capsule falls freely into the water tank to complete cooling.

[0027] S6: The steam used in the non-demolding and demolding processes can be discharged through the first exhaust valve and the second exhaust valve respectively, and enter the interior of the condenser to condense into water flow, which is then discharged through the drain pipe and re-enters the interior of the water storage tank to achieve circulation.

[0028] The beneficial effects of this invention are as follows:

[0029] This invention reuses the steam used for heating raw materials. While heating the raw materials with high-temperature steam, the fluidity of the steam also serves as a power source for automatic mixing and stirring. Both processes are powered by high-temperature steam, eliminating the need for multiple power units. The mixing and heating of raw materials can be achieved simultaneously by heating the water flow, resulting in lower energy consumption, significantly reducing resource consumption, and improving energy utilization.

[0030] Meanwhile, by further utilizing high-temperature steam, the continuous input of high-temperature steam is used as pressure to act on the vulcanizing capsule, which can realize the automatic demolding of the vulcanizing capsule. The high-temperature steam can be condensed back into water for cooling the vulcanizing capsule. At the same time, the water is also heated during the cooling process of the vulcanizing capsule, thereby shortening the time for subsequent water heating and reducing energy consumption. Steam is used as the main energy source throughout the entire process, eliminating the need for multiple power mechanisms. The steam can also be recycled, resulting in extremely high resource utilization. The system has a small footprint and is suitable for batch processing. Attached Figure Description

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] like Figures 1 to 7 As shown in the embodiment of the present invention, a high-stability tire vulcanizing bladder production device includes a water storage tank 1. A first frame 3 is fixedly installed near the right end of the water storage tank 1. A mixing tank 2 located above the water storage tank 1 is fixedly installed on the inner side of the first frame 3.

A steam assembly 5 is fixedly installed at the right end of the mixing tank 2. The bottom end of the mixing tank 2 has an opening. The mixing tank 2 has a discharge port 15. A forming cavity 16 located below the discharge port 15 is fixedly installed at the bottom of the mixing tank 2. A forming mold 18 is provided at the bottom of the forming cavity 16. Horizontal guide rails 17 are fixedly installed on both the front and rear sides of the top of the water storage tank 1. A water pump 9 is fixedly installed at the right end of the water storage tank 1. The output end of the water pump 9 is connected to the water storage tank 1.

A material injection port 6 is fixedly connected to one side of the top of the mixing tank 2.

[0041] In actual use, first ensure the capacity of the water flow inside the water storage tank 1 and replenish it as needed. Then, select the appropriate raw materials according to the type of processing and inject them into the mixing tank 2 through the feeding port 6. At the same time, turn on the power of the device to complete the preparation.

[0042] like Figure 1 and Figure 2As shown, the molding mold 18 is located on the inner side of the molding cavity 16. The top of the two second frames 4 is provided with mounting plates 20. Guide blocks 21 are fixedly installed on the front and rear sides of the bottom of the mounting plate 20. The guide blocks 21 are movably engaged with the transverse guide rail 17. The top of the mounting plate 20 is fixedly installed with a longitudinal telescopic rod 19. The top of the longitudinal telescopic rod 19 is fixedly connected to the bottom of the molding mold 18. The front and rear sides of the left end of the mounting plate 20 are fixedly installed with transverse telescopic rods 22. The other end of the transverse telescopic rod 22 is connected to the side of the transverse guide rail 17.

[0043] When processing vulcanized capsules, the molding mold 18 must be kept inside the molding cavity 16, and the bottom end of the molding mold 18 must be in contact with the bottom end of the molding cavity 16 to complete the sealing operation. When demolding is required after the vulcanized capsule is formed, the longitudinal telescopic rod 19 can be shortened first to lower the molding mold 18 and remove it from the molding cavity 16. Then, the transverse telescopic rod 22 can be shortened and, under the guidance of the guide block 21 and the transverse guide rail 17, the molding mold 18 can be moved to the left until the molding mold 18 is directly below the demolding component 23, waiting for the subsequent demolding operation. After demolding, the molding mold 18 should return to the inside of the molding cavity 16 under the combined action of the transverse telescopic rod 22 and the longitudinal telescopic rod 19, waiting for the secondary vulcanized capsule forming operation.

[0044] like Figure 3 and Figure 4 as well as Figure 5 As shown, the steam assembly 5 includes a steam tank 501. A heating rod 502 is fixedly installed in the middle of the inner cavity of the steam tank 501. A water inlet 503 is fixedly connected to the side of the steam tank 501 near the bottom end. The water inlet 503 is connected to the circulation pipe 24. A steam pipe 504 is fixedly connected to the top of the steam tank 501. A power tank 7 is fixedly installed in the middle of the top of the mixing tank 2. A main shaft 13 is movably installed in the middle of the inner cavity of the power tank 7. A sleeve is fixedly connected to the outer side of the main shaft 13 located in the power tank 7. The impeller 8 inside and the bottom end of the main shaft 13 pass through the bottom end of the power tank 7 and the top end of the mixing tank 2 and are fixedly connected at equal angles to the stirring shaft 14 located inside the mixing tank 2. The left end of the power tank 7 is fixedly connected to the first air supply pipe 10. The bottom end of the first air supply pipe 10 is fixedly connected to the three-way valve 11. The right end of the three-way valve 11 is fixedly connected to the second air supply pipe 12. The other end of the second air supply pipe 12 is connected to the molding cavity 16. The left end of the three-way valve 11 is connected to the demolding assembly 23. Example

[0045] During the molding of the vulcanized capsule, water is first drawn from the water tank 1 by the water pump 9 and injected into the steam tank 501 through the circulation pipe 24. At this time, the water is heated by the heating rod 502 to generate steam, which is then discharged through the steam pipe 504 and enters the power tank 7. Simultaneously, the impeller 8 is driven to rotate, thereby realizing the rotation of the main shaft 13, and finally realizing the circumferential movement of the stirring shaft 14 to mix and stir the raw materials in the mixing tank 2. The stirred raw materials can be discharged through the discharge port 15 and squeezed between the molding cavity 16 and the molding mold 18. At the same time, the steam entering the power tank 7 can be discharged through the first gas supply pipe 10 and introduced into the molding cavity 16 through the three-way valve 11 and the second gas supply pipe 12 to heat the raw materials inside, completing the heating and extrusion molding. Some of the steam can be discharged through the left end of the three-way valve 11.

[0046] By reusing the steam used for heating raw materials, the steam can be used to heat the raw materials at high temperature, and the steam's flowability can also be used as a power source to automatically mix and stir the raw materials. Both of these processes are powered by high-temperature steam, so the device does not need to be equipped with multiple power units. Only water heating is required to achieve simultaneous mixing and heating of raw materials, resulting in low energy consumption, significantly reducing resource consumption, and improving energy utilization.

[0047] like Figure 1 and Figure 2 as well as Figure 6 and Figure 7 As shown, the demolding assembly 23 includes a temporary storage tube 231. The top end of the temporary storage tube 231 is connected to the top end of the inner side of the second frame 4. An air inlet valve 232 is fixedly connected to the right side of the temporary storage tube 231 near the bottom end. The air inlet valve 232 is connected to a three-way valve 11. A piston plate 235 is movably sleeved inside the temporary storage tube 231. The piston plate 235 moves up and down relative to the temporary storage tube 231. A piston rod 236 is fixedly connected to the bottom end of the piston plate 235. The bottom end of the piston rod 236 passes through the bottom end of the temporary storage tube 231 and is fixedly installed with a vacuum suction cup 238. A return spring 237 is movably sleeved on the outer side. The upper and lower ends of the return spring 237 are respectively connected to the bottom end of the piston plate 235 and the bottom end of the inner cavity of the temporary storage tube 231. The upper and lower ends of the left side of the temporary storage tube 231 are respectively fixedly connected to the second exhaust valve 234 and the first exhaust valve 233. The other ends of the first exhaust valve 233 and the second exhaust valve 234 are fixedly connected to the condenser box 239. The left end of the condenser box 239 is fixedly connected to the drain pipe 2310 located above the water storage tank 1. Solenoid valves are installed inside the first exhaust valve 233 and the second exhaust valve 234. Example

[0048] After the vulcanized capsule is formed, the molding die 18 can be controlled to move below and contact the demolding assembly 23. When demolding is not required, high-temperature steam can enter the inlet valve 232 through the three-way valve 11. At this time, the solenoid valve inside the first exhaust valve 233 remains open, while the solenoid valve inside the second exhaust valve 234 remains closed. High-temperature steam can then be discharged through the first exhaust valve 233 and enter the condenser 239. When demolding is required, the solenoid valve inside the first exhaust valve 233 can be closed, and the solenoid valve inside the second exhaust valve 234 can be opened. At this time, the steam can apply a certain pressure to the piston plate 235, and the piston plate 235 and piston rod 2... As 36 moves upward, the return spring 237 is compressed. At this time, the vacuum suction cup 238 is pre-activated to adsorb between itself and the vulcanizing capsule. The vacuum suction cup 238 moves upward, causing the vulcanizing capsule to detach from the molding mold 18 and complete the demolding process. When the piston plate 235 moves above the second exhaust valve 234, the high-temperature steam can be discharged through the second exhaust valve 234 and enter the interior of the condenser 239. After condensation, the steam entering the condenser 239 can be discharged through the drain pipe 2310 and flow back into the interior of the water storage tank 1 to complete the cycle. After demolding, the vulcanizing capsule can be allowed to fall freely into the interior of the water storage tank 1 and come into contact with the cooling water by closing the vacuum suction cup 238, thus completing the cooling process.

[0049] By further utilizing high-temperature steam, the continuous input of high-temperature steam is used as pressure to act on the vulcanizing capsule, which can achieve automatic demolding of the vulcanizing capsule. The high-temperature steam can be condensed back into water for cooling the vulcanizing capsule. At the same time, the water is also heated during the cooling process of the vulcanizing capsule, thereby shortening the time for subsequent water heating and reducing energy consumption. Steam is used as the main energy source throughout the entire process, eliminating the need for multiple power mechanisms. In addition, the steam can be recycled, resulting in extremely high resource utilization. The process requires a small footprint and is suitable for batch processing.

[0050] A production method for a high-stability tire vulcanizing bladder production apparatus includes the following steps:

[0051] S1: First, fill the water tank 1 with clean water and turn on the power of the water pump 9. Then, inject the raw materials into the mixing tank 2 through the injection port 6 for mixing. Place the molding mold 18 on the inner side of the molding cavity 16 to complete the preparation work.

[0052] S2: The raw material injected through the injection port 6 enters the interior of the mixing tank 2. At this time, the water pump 9 is turned on to draw the water in the water storage tank 1 into the steam tank 501 through the circulation pipe 24, and the heating rod 502 is turned on to heat it. The steam generated by heating can be discharged through the steam pipe 504 and enter the interior of the power tank 7, and drive the impeller 8 to rotate. At this time, the main shaft 13 rotates accordingly and drives the stirring shaft 14 to stir and complete the mixing of the raw materials.

[0053] S3: At the same time, steam can be discharged through the first gas supply pipe 10 and enter the interior of the three-way valve 11. Some steam will be injected into the interior of the molding cavity 16 through the second gas supply pipe 12. At this time, the uniformly mixed raw material can be discharged through the discharge port 15 and act on the position between the molding cavity 16 and the molding mold 18. At this time, steam can enter the interior of the molding cavity 16 to heat the raw material. Combined with the extrusion molding between the molding cavity 16 and the molding mold 18, the molding process of the vulcanized capsule is completed.

[0054] S4: After the vulcanized capsule is formed, the longitudinal telescopic rod 19 can be shortened to drive the forming mold 18 to descend, and the transverse telescopic rod 22 can be shortened to drive the forming mold 18 to move to the left until it is below the demolding component 23. At this time, the longitudinal telescopic rod 19 can be extended until the vulcanized capsule at the top of the forming mold 18 contacts the bottom of the demolding component 23.

[0055] S5: At this time, close the solenoid valve of the first exhaust valve 233 and open the solenoid valve inside the second exhaust valve 234. At the same time, open the vacuum suction cup 238. At this time, the vacuum suction cup 238 can be adsorbed between the vulcanizing capsule and the vacuum suction cup 238. At this time, the steam inside the three-way valve 11 can be input into the interior of the temporary storage tube 231 through the air inlet valve 232 and apply an upward thrust to the piston plate 235 until the piston plate 235 rises, thereby driving the piston rod 236 and the vacuum suction cup 238 to rise, and finally driving the vulcanizing capsule to rise to complete demolding. Then, the molding mold 18 returns to the initial working position, the vacuum suction cup 238 is closed, and the sulfur capsule falls freely into the water storage tank 1 to complete cooling.

[0056] S6: The steam used in the non-demolding and demolding processes can be discharged through the first exhaust valve 233 and the second exhaust valve 234 respectively, and enter the interior of the condenser 239 to condense into water flow and be discharged through the drain pipe 2310 to re-enter the interior of the water storage tank 1 to achieve circulation.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

A production method for a high-stability tire vulcanizing bladder production apparatus according to any one of claims 1-6, characterized in that: Includes the following methods: S1: First, fill the water tank (1) with clean water and turn on the power of the water pump (9). Then, inject the raw materials into the mixing tank (2) through the injection port (6) for mixing. Place the molding mold (18) on the inner side of the molding cavity (16) to complete the preparation work. S2: The raw material injected through the injection port (6) enters the interior of the mixing tank (2). At this time, the water pump (9) is turned on to draw the water in the water storage tank (1) into the steam tank (501) through the circulation pipe (24), and the heating rod (502) is turned on for heating. The steam generated by heating can be discharged through the steam pipe (504) and enter the interior of the power tank (7), and drive the impeller (8) to rotate.
