Description

Technical Field

[0001] This utility model relates to the field of tire vulcanizing bladder demolding technology, specifically a tire vulcanizing bladder demolding device. 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, through which a heating medium is introduced to assist the vulcanizing machine in shaping and vulcanization. The type of vulcanizing bladder varies depending on the structure of the vulcanizing machine. Various shaping vulcanizing machines mainly use three types of bladders: Type A, Type B, and Type AB. During the vulcanization process, a drum-shaped base is used to shape and support the inner side of the vulcanizing bladder. In existing methods, when the vulcanizing capsule is ejected from the base and vulcanizing capsule after vulcanization, the vulcanizing capsule is tightly attached to the drum-shaped base, and the diameter of the vulcanizing capsule gradually decreases from the center to both ends. This makes it difficult to demold the vulcanizing capsule. Demolding is usually done manually, which is time-consuming, labor-intensive, and can easily cause damage to the vulcanizing capsule. For example, the Chinese authorized patent with announcement number CN 217073455 U (a vulcanized capsule demolding device): it uses a cylinder to push out a suction and pull component and multiple suction cups to adsorb the vulcanized capsule, and realizes automatic separation of the vulcanized capsule from the mold by rotating the rotary table; it uses three contact blocks at different positions in conjunction with limit switches to control the adsorption state of the vulcanized capsule, and a spring makes the contact blocks automatically return to their original positions after adsorption is completed; this utility model has a simple structure, and the use of a rotary table realizes the free switching of the vulcanized capsule between the vulcanization position and the demolding position, which improves the work efficiency. This technical solution solves the above problems; However, the technical solution of this utility model still has some technical problems. The vulcanized capsule demolding device adopts an upward suction method during demolding. Since the vulcanized capsule and the drum-shaped inner mold are in close contact, a negative pressure is easily formed between the vulcanized capsule and the drum-shaped inner mold during upward suction. Under the action of negative pressure and friction, the vulcanized capsule rotates and is demolded, which can easily lead to the vulcanized capsule breaking and affect the quality of the vulcanized capsule.

[0003] To address this, a tire vulcanizing bladder demolding device is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a tire vulcanizing bladder demolding device to solve the problem in the background art where the vulcanizing bladder demolding device uses an upward suction method during demolding. Because the vulcanizing bladder and the drum-shaped inner mold are in close contact, a negative pressure is easily formed between the vulcanizing bladder and the drum-shaped inner mold during upward suction. Under the action of negative pressure and friction, the vulcanizing bladder rotates and is demolded, which can easily lead to the vulcanizing bladder breaking and affect the quality of the vulcanizing bladder.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tire vulcanizing bladder demolding device, comprising a main support frame: A rotating disk is rotatably mounted inside the lower end of the main support via bearings. The upper end of the rotating disk has four hollow discharge shafts in an internal annular array and four forming molds in an internal annular array. The hollow discharge shafts, forming molds, rotating air intake ring, and rotating disk are all slidably connected up and down via slots. A rotating air intake ring is fixedly mounted on the lower end of the rotating disk, and a hollow air delivery ring is rotatably mounted on the outside of the rotating air intake ring. An air inlet pipe is located on one side of the hollow air conveying ring. The air inlet pipe is fixedly connected to the hollow air conveying ring. Four air blowing holes are arranged in a ring array at the upper end of the hollow discharge shaft. Four air inlet grooves are provided on the outside of the rotating air inlet ring. Two discharge air holes are provided on the inner side of the hollow air conveying ring.

[0006] Preferably, a sealing cover is installed at the upper end of the hollow gas conveying ring, and the sealing cover is fixedly connected to the hollow gas conveying ring.

[0007] Preferably, a rotary motor is fixedly installed at the lower end of the main support, and the rotary motor is connected to the rotary disk via a coupling.

[0008] Preferably, a support platform is installed at the lower end of the hollow gas conveying ring, the hollow gas conveying ring is fixedly connected to the support platform, and the support platform is fixedly connected to the main support.

[0009] Preferably, a telescopic rod is fixedly installed at the upper end of the main support, and a vulcanizing component is fixedly installed at the telescopic end of the telescopic rod.

[0010] Preferably, a control box is installed on one side of the front end face of the main support, and the control box is fixedly connected to the main support.

[0011] Preferably, a support leg is fixedly installed at the lower end of the main support frame, and the support leg is fixedly connected to the main support frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model utilizes high-pressure air by installing a hollow discharge shaft to push the shaft upwards, causing it to push the tire vulcanizing bladder open to a certain height. Air then enters the lower end of the tire vulcanizing bladder through the air blowing hole at the upper end of the shaft, causing the bladder to separate from the molding mold under the action of air. This eliminates the negative pressure between the bladder and the mold, making it easier for workers to remove the bladder from the top of the mold, enhancing the effectiveness of the device, effectively preventing the bladder from breaking when removed, and ensuring the quality of the bladder. 2. This utility model features four air inlet slots that can be matched with two discharge air holes inside the hollow air conveying ring. When the air inlet slots match the discharge air holes, air can enter the hollow discharge shaft. When the air inlet slots and discharge air holes do not match, air cannot enter the hollow discharge shaft. This ensures that only two discharges and two vulcanization operations can be performed simultaneously from the four forming molds inside the device, allowing the discharge and vulcanization operations to proceed synchronously. This enhances the practicality of the device. The mounting support platform provides support, prevents the rotating disc from tilting, and ensures the stability of the device during operation.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Please see Figure 1-5 One embodiment of this utility model is a tire vulcanizing bladder demolding device, comprising a main support 1: The rotating disk 2 is rotatably mounted inside the lower end of the main support 1 via bearings. The upper end of the rotating disk 2 has four hollow discharge shafts 4 arranged in an internal annular array. The hollow discharge shafts 4 can be installed using high-pressure air to push them upward, causing them to push the tire vulcanizing capsule open to a certain height. Then, air enters the lower end of the tire vulcanizing capsule through the air blowing hole at the upper end of the hollow discharge shaft 4, causing the tire vulcanizing capsule to separate from the molding mold 3 under the action of air. This eliminates the negative pressure between the tire vulcanizing capsule and the molding mold 3, making it easier for workers to remove the tire vulcanizing capsule from the upper end of the molding mold 3, enhancing the effectiveness of the device, effectively preventing the tire vulcanizing capsule from breaking when it is removed, and ensuring the quality of the tire vulcanizing capsule. The upper end of the rotating disk 2 has four molding molds 3 arranged in an internal annular array. The hollow discharge shafts 4 are slidably connected to the molding molds 3, the rotating air intake ring 12, and the rotating disk 2 via slots. The rotating air intake ring 12 is fixedly installed at the lower end of the rotating disk 2, and a hollow air supply ring 11 is rotatably installed on the outside of the rotating air intake ring 12. An air inlet pipe 9 is located on one side of the hollow air conveying ring 11 and is fixedly connected to the hollow air conveying ring 11. Four air blowing holes are arranged in a ring array at the upper end of the hollow discharge shaft 4. Four air inlet grooves 13 are provided on the outside of the rotating air inlet ring 12. Two discharge air holes are provided on the inner side of the hollow air conveying ring 11. The four air inlet grooves 13 can be matched with the two discharge air holes on the inner side of the hollow air conveying ring 11. When the air inlet grooves 13 match the discharge air holes, air can enter the interior of the hollow discharge shaft 4. When the air inlet grooves 13 do not match the discharge air holes, air cannot enter the interior of the hollow discharge shaft 4. This ensures that only two of the four forming molds 3 can discharge material and perform two vulcanization operations simultaneously, allowing the discharge and vulcanization operations to proceed synchronously and enhancing the practicality of the device.

[0017] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A sealing cover plate 15 is installed at the upper end of the hollow gas conveying ring 11, and the sealing cover plate 15 is fixedly connected to the hollow gas conveying ring 11. A rotary motor 14 is fixedly installed at the lower end of the main support 1, and the rotary motor 14 is connected to the rotary disk 2 through a coupling. A support platform 8 is installed at the lower end of the hollow gas conveying ring 11. The support platform 8 can provide support to prevent the rotary disk 2 from tilting and ensure the stability of the device during operation. The hollow gas conveying ring 11 is fixedly connected to the support platform 8, and the support platform 8 is fixedly connected to the main support 1. A telescopic rod 5 is fixedly installed at the upper end of the main support 1, and a vulcanizing component 7 is fixedly installed at the telescopic end of the telescopic rod 5. A control box 6 is installed on one side of the front face of the main support 1, and the control box 6 is fixedly connected to the main support 1. A support leg 10 is fixedly installed at the lower end of the main support 1, and the support leg 10 is fixedly connected to the main support 1.

[0018] Working Principle: The operator connects an external high-pressure air pump to the air inlet pipe 9. During the molding process of the vulcanizing capsule, the telescopic rod 5 pushes the vulcanizing component 7 downwards, allowing it to engage with the molding mold 3 to form a vulcanizing space. After vulcanization, the formed vulcanizing capsule is located inside the molding mold 3. When demolding the vulcanizing capsule, the rotary motor 14 rotates the rotary disk 2 180 degrees, aligning the two discharge air holes inside the hollow air ring 11 with the air inlet groove 13 below the molding mold 3. The high-pressure air pump starts, allowing high-pressure air to enter the hollow discharge shaft 4, causing the air pressure to push the hollow discharge shaft 4 upwards. This, in turn, pushes the vulcanizing capsule upwards, eliminating the negative pressure between the vulcanizing capsule and the molding mold 3. The operator can then easily peel off the vulcanizing capsule. The device can utilize high-pressure air to push the hollow discharge shaft 4 upwards, allowing it to displace the tire vulcanizing rubber. The bladder is opened to a certain height, and air enters the lower end of the tire vulcanizing bladder through the air blowing hole at the upper end of the hollow discharge shaft 4. This causes the tire vulcanizing bladder to separate from the molding mold 3 under the action of air, eliminating the negative pressure between the tire vulcanizing bladder and the molding mold 3. This makes it easier for workers to remove the tire vulcanizing bladder from the upper end of the molding mold 3, enhancing the effectiveness of the device and effectively preventing the tire vulcanizing bladder from breaking when it is removed, thus ensuring the quality of the tire vulcanizing bladder. Four air inlet slots 13 are provided to match the two discharge air holes inside the hollow air supply ring 11. When the air inlet slots 13 match the discharge air holes, air can enter the interior of the hollow discharge shaft 4. When the air inlet slots 13 do not match the discharge air holes, air cannot enter the interior of the hollow discharge shaft 4. This ensures that only two discharges and two vulcanization operations can be performed simultaneously on the four molding molds 3 inside the device, allowing the discharge and vulcanization operations to proceed synchronously, enhancing the practicality of the device. The support platform 8 provides support and prevents the rotating disk 2 from tilting, ensuring the stability of the device during operation.
