Description

Technical Field

[0001] This utility model relates to an air spring, specifically a vulcanization mold for a large curved air spring capsule. Background Technology

[0002] Large-curve air springs are one of the main types of air springs used in rail vehicles. Compared with other types of air springs, large-curve air springs are less dependent on additional air chambers, thus ensuring higher safety when vehicles pass through curves without air. Therefore, large-curve air springs have been widely used in high-speed trains and metro / urban rail vehicles, and are a key component of the vehicle's secondary suspension.

[0003] In the production of air springs, vulcanization is required to obtain the desired physical properties and shape. Since the vulcanization mold absorbs heat during vulcanization, its temperature rises afterward. Excessive temperature can affect the vulcanization quality of subsequent products, leading to uneven or over-vulcanization. Therefore, the mold is cooled after vulcanization. Common cooling methods include natural cooling, suitable for situations where the vulcanization cycle is not critical, but with a slow cooling rate; forced air cooling, which involves blowing cold air onto the surface of the vulcanization mold to accelerate the cooling process, suitable for situations with specific vulcanization cycle requirements, but requires manual operation; and cooling channels inside the mold, using coolant to cool it. However, in existing technologies, the vulcanization mold consists of two parts, an upper and a lower one, with the upper mold being movable, making cooling difficult. A separate pipe connection between the upper and lower molds is required, increasing the cooling complexity. Therefore, we propose a vulcanization mold for a large-curve air spring capsule. Utility Model Content

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, this utility model discloses a vulcanizing mold for a large-diameter air spring capsule, comprising an mounting plate 1, a support plate 2, and a top plate 3. The mounting plate 1 and the top plate 3 are connected by the support plate 2. A lower mold 4 is provided on the upper surface of the mounting plate 1, and an upper mold 5 is provided on the top plate 3. A hydraulic telescopic rod 6 is provided on the top plate 3. A vulcanizing groove 7 is formed on the side surface of the lower mold 4 adjacent to the upper mold 5. A water inlet pipe 8 is fixedly connected to the left side surface of the lower mold 4, and a water outlet pipe 9 is fixedly connected to the right side surface of the lower mold 4. A cooling groove 10 is formed inside the lower mold 4, and a cooling groove 10 is formed on the upper surface of the lower mold 4. The fixed connection has two joints 11. The lower surface of the upper mold 5 is provided with a mating interface 13 that is compatible with the two joints 11. The cooling tank 10 is connected to the joints 11, the water inlet pipe 8 and the water outlet pipe 9 respectively. The joints 11 are provided with a docking component. Through the setting of the joints 11, the mating interface 13 and the docking component, the cooling channels in the two molds can be automatically connected when the upper mold 5 and the lower mold 4 are closed for vulcanization. Thus, when cooling, only cooling oil needs to be supplied to the water inlet pipe 8 on the lower mold 4 to complete the cooling of the two molds, making the cooling more convenient.

[0026] The docking assembly includes a mounting plate 14. A closed cylinder 15 and a sealing gasket 16 are fixedly connected to the upper surface of the mounting plate 14. A sealing groove 17 adapted to the closed cylinder 15 and the sealing gasket 16 is formed on the lower surface of the upper mold 5. A cavity 18 is formed inside the interface 13. A conical sealing ring 19 is fixedly connected to the bottom wall of the cavity 18. A telescopic groove 20 is formed on the top wall of the cavity 18. A spring 21 is fixedly connected to the top wall of the telescopic groove 20. A sealing plate 22 is fixedly connected to the lower end of the spring 21. A rubber sealing ring 23 is fitted on the outer surface of the sealing plate 22. The rubber sealing ring 23 is slidably connected to the inner wall of the telescopic groove 20. A connecting rod 24 is fixedly connected to the lower end of the sealing plate 22. The lower end of the connecting rod 24 extends into the cavity 18. A sealing block 25 is fixedly connected to the lower end of the connecting rod 24. The lower surface of the sealing block 25 is also conical. The lower surface of the sealing block 25 is connected to the conical sealing ring 25. The ring 19 is compatible with the connector 11. The outer surface of the connector 11 is provided with a threaded groove. The outer surface of the connector 11 is threaded with a connecting cylinder 26. The inner wall of the connecting cylinder 26 is fixedly connected with a filter screen 27. The lower mold 4 and the upper mold 5 are both provided with annular collection grooves 28. The inner wall of the vulcanizing tank 7 is provided with a ventilation groove 29. The ventilation groove 29 communicates with the interior of the annular collection groove 28. The right side surface of the lower mold 4 is fixedly connected with an exhaust pipe 30. The interior of the lower mold 4 and the upper mold 5 are both provided with exhaust grooves 31. The exhaust grooves 31 are the same as the annular collection groove 28 and the exhaust pipe 30, respectively. The upper side surface of the connecting cylinder 26 is fixedly connected with a push rod 12. Through the setting of the annular collection groove 28 and the exhaust groove 31, the harmful gases generated during the vulcanization process can be effectively discharged, and they are all discharged through the exhaust pipe 30 on the lower mold 4, which facilitates the subsequent connection of the exhaust pipe 30 and avoids the leakage of harmful gases from affecting the surrounding environment.

[0027] During operation, as the upper mold 5 descends via the hydraulic telescopic rod 6 for vulcanization, the connector 11 enters the interior of the interface 13. At this time, the sealing cylinder 15 enters the interior of the inner sealing groove 17. Subsequently, as the movement continues, the connector 11, with the help of the connecting cylinder 26 and the push rod 12, contacts the sealing block 25. The sealing block 25 is compressed and stops moving downwards. At this time, the upper mold 5 continues to move, causing the sealing block 25 to disengage from the conical sealing ring 19, thereby releasing the seal on the interface 13. When the sealing block 25 disengages from the conical sealing ring 19, it simultaneously compresses the spring 21 with the help of the sealing plate 22. At this time, cooling oil is injected into the interior of the water inlet pipe 8 through external equipment. The cooling oil enters the interior of the cooling tank 10 through the water inlet pipe 8 and is then diverted. The diverted cooling oil... Part of the cooling oil is used to cool the lower mold 4, and part of it enters the upper mold 5 through the left connector 11 and the interface 13 to cool the upper mold 5. After the cooling oil flows in the upper mold 5, it flows back into the lower mold 4 through the right interface 13 and the connector 11, and is discharged through the water outlet pipe 9. The harmful gases generated during vulcanization will enter the annular collection tank 28 through the ventilation groove 29. The harmful gases in the annular collection tank 28 of the upper mold 5 will be transferred to the lower annular collection tank 28 through the cooperation of the interface 13 and the connector 11. Thus, after the harmful gases enter the annular collection tank 28, they enter the exhaust pipe 30 through the exhaust groove 31 and are then transported to the purification equipment through the exhaust pipe 30.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
