Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to water-based mold processing molds. Background Technology

[0002] In the tire manufacturing process, the water bladder (vulcanizing bladder) is a key component, used to transmit high temperature and high pressure during tire vulcanization to ensure tire body shaping and tread pattern setting.

[0003] Currently, most water tire processing molds adopt integral casting or simple split mold structure. The split mold structure mainly relies on hydraulic cylinders to drive the moving mold to achieve up and down reciprocating motion to complete the mold opening and closing operation. However, in the actual production process, the hydraulic cylinder piston rod is in high-speed and frequent reciprocating motion. Due to the special working environment of high temperature and high dust in the vulcanization workshop, coupled with the high operating frequency and heavy load of the mold, the lubrication conditions on the piston rod surface are easily deteriorated, resulting in deviation of the moving mold's motion trajectory. Therefore, it is necessary to propose a water tire processing mold to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a water-based tire processing mold.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A water-based tire processing mold includes a base plate and a top plate. Multiple sets of first support rods are fixedly connected between the base plate and the top plate. A hydraulic cylinder and a lubrication cylinder are fixedly connected to the upper end of the top plate. The telescopic end of the hydraulic cylinder extends through the top plate to below it. A sliding plate is fixedly connected to the end of the telescopic end of the hydraulic cylinder. The sliding plate is slidably connected to the outer wall of the multiple sets of first support rods. A fixed mold is fixedly connected to the upper end of the base plate. A movable mold is installed at the lower end of the sliding plate and moves inside the fixed mold. A sliding rod is slidably connected to the lower end of the top plate and extends slidably into the lubrication cylinder. A piston is movably connected inside the lubrication cylinder, and its lower end face is fixedly connected to the end of the sliding rod. Two sets of connecting pipes are fixedly connected to the end face of the lubrication cylinder, each containing a one-way valve. One set of connecting pipes has a spray ring fixedly connected to its end, and the spray ring is sleeved on the outer wall of the telescopic end of the hydraulic cylinder. A reset mechanism for driving the sliding rod to reset is installed inside the lubrication cylinder.

[0007] Preferably, the reset mechanism includes a spring sleeved on the outer wall of the slide rod, one end of the spring being fixedly connected to the lower end face of the piston, and the other end of the spring being fixedly connected to the bottom of the lubrication cylinder.

[0008] Preferably, the top plate end face is provided with two sets of sliding grooves, and each set of sliding grooves is movably connected to a slider. The slider is connected to a brush plate through a second support rod. The inner and outer walls of the brush plate are both arc-shaped and cover the outer wall of the hydraulic cylinder extension end. The brush plate is located below the spray ring.

[0009] Preferably, a connecting rod is fixedly connected to the inner wall of the slide groove, and the slider is slidably connected to the outer wall of the connecting rod, with both outer walls of the slider in close contact with the inner wall of the slide groove.

[0010] Preferably, a second spring is sleeved on the outer wall of the connecting rod, one end of the second spring is fixedly connected to the side wall of the slider, and the other end of the second spring is fixedly connected to the inner wall of the groove.

[0011] Preferably, a buffer pad is fixedly connected to the end of the slide bar away from the lubrication cylinder, and the buffer pad is made of rubber material.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model, by setting components such as a lubrication cylinder, a spray ring, and a brush plate, allows the lubricant to be drawn in through a connecting pipe when the hydraulic cylinder drives the slide plate to move downwards. When the slide plate returns, it pushes the slide rod to move the piston upwards, pressing the lubricant into the spray ring to form a uniform oil film. At the same time, the brush plate, under the action of the second spring, always keeps close contact with the piston rod surface, completing dust removal and lubricant coating simultaneously during the extension and retraction process. This effectively solves the problem of moving mold movement deviation caused by piston rod lubrication failure in high-temperature and dusty environments, improving the mold running accuracy and service life.

[0014] 2. This utility model ensures the reliability and adaptability of the lubrication system by setting up a dual elastic reset mechanism with spring one and spring two. Spring one ensures the automatic intake and discharge of lubricant, realizing the cyclic supply of lubrication process, while spring two enables the brush plate to adapt to the thermal deformation and surface condition changes of the piston rod, maintaining a constant contact pressure.

Detailed Implementation

[0019] 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.

[0020] Reference Figure 1-3 A water-based tire processing mold includes a base plate 1 and a top plate 2. Multiple sets of first support rods 3 are fixedly connected between the base plate 1 and the top plate 2. A hydraulic cylinder 4 and a lubrication cylinder 8 are fixedly connected to the upper end of the top plate 2. The telescopic end of the hydraulic cylinder 4 extends through the top plate 2 to the bottom of the top plate 2. A sliding plate 5 is fixedly connected to the end of the telescopic end of the hydraulic cylinder 4. The sliding plate 5 is slidably connected to the outer wall of the multiple sets of first support rods 3. A fixed mold 6 is fixedly connected to the upper end of the base plate 1. A moving mold 7 is installed at the lower end of the sliding plate 5. The moving mold 7 moves inside the fixed mold 6. A sliding rod 9 is slidably connected to the lower end of the top plate 2. The sliding rod 9 extends slidably into the lubrication cylinder 8. A piston 11 is movably connected inside the lubrication cylinder 8, and its lower end face is fixedly connected to the end of the sliding rod 9. Two sets of connecting pipes 13 are fixedly connected to the end face of the lubrication cylinder 8, and each set is equipped with a one-way valve. One set of connecting pipes 13 is fixedly connected to the end of a spray ring 15, and the spray ring 15 is sleeved on the outer wall of the telescopic end of the hydraulic cylinder 4. A reset mechanism for driving the sliding rod 9 to reset is installed inside the lubrication cylinder 8.

[0021] Furthermore, through the design of the lubrication cylinder 8 and the spray ring 15, lubricant can be automatically sprayed onto the surface of the piston rod during the extension and retraction of the hydraulic cylinder 4, effectively avoiding lubrication failure caused by high temperature dust, and reducing the frequency of manual maintenance. It should be noted that in actual use, another connecting pipe 13 is connected to an external container containing lubricant, and the movement of the sliding plate 5 is driven by the hydraulic cylinder 4 to abut against the sliding rod 9, thereby realizing the movement of the piston 11.

[0022] The reset mechanism includes a spring 12 sleeved on the outer wall of the slide bar 9. One end of the spring 12 is fixedly connected to the lower end face of the piston 11, and the other end of the spring 12 is fixedly connected to the bottom of the lubrication cylinder 8.

[0023] Furthermore, the reset function of spring 12 ensures that piston 11 can quickly return to its original position after the lubricant is sprayed out, and at the same time, the movement of piston 11 can draw external lubricant into lubrication cylinder 8 for subsequent use.

[0024] Two sets of sliding grooves 14 are provided through the end face of the top plate 2. A slider 19 is movably connected in each set of sliding grooves 14. A brush plate 16 is connected to the slider 19 through a second support rod 17. The inner and outer walls of the brush plate 16 are both arc-shaped and cover the outer wall of the telescopic end of the hydraulic cylinder 4. The brush plate 16 is located below the spray ring 15. A connecting rod 18 is fixedly connected to the inner wall of the sliding groove 14. The slider 19 is slidably connected to the outer wall of the connecting rod 18. Both outer walls of the slider 19 are in close contact with the inner wall of the sliding groove 14. A second spring 20 is sleeved on the outer wall of the connecting rod 18. One end of the second spring 20 is fixedly connected to the side wall of the slider 19, and the other end of the second spring 20 is fixedly connected to the inner wall of the sliding groove 14.

[0025] Furthermore, the curved surface design of the brush plate 16 fits the outer wall of the extension end of the hydraulic cylinder 4, which can simultaneously clean the surface dust and apply lubricant when the piston rod extends and retracts. Meanwhile, the spring 20 provides elastic support for the slider 19, ensuring that the brush plate 16 always remains in close contact with the piston rod surface.

[0026] A buffer pad 10 is fixedly connected to the end of the slide bar 9 away from the lubrication cylinder 8. The buffer pad 10 is made of rubber material.

[0027] In this invention, when the device is in use: the operator activates the hydraulic cylinder 4, and its telescopic end extends downward, pushing the slide plate 5 to slide along the support rod 3 towards the fixed mold 6. The moving mold 7 moves downward synchronously with the slide plate 5, gradually closing with the fixed mold 6 to form a cavity. As the slide plate 5 moves downward, its end face gradually separates from the buffer pad 10 at the top of the slide rod 9. Under the restoring force of the spring 12, the slide rod 9 drives the piston 11 to move downward. The movement of the piston 11 can draw in new lubricant from the external lubricant container through another connecting pipe 13, ensuring a continuous supply of liquid to the lubrication cylinder 8.

[0028] When the hydraulic cylinder 4 drives the slide plate 5 and the moving mold to reset, the slide plate 5 gradually comes into contact with the slide rod 9, causing the piston 11 to slide upward. Then, the lubricant pre-stored in the lubrication cylinder 8 is pressed into the spray ring 15 through the connecting pipe 13. The multiple spray holes on the spray ring 15 spray the lubricant evenly onto the piston rod surface of the hydraulic cylinder 4.

[0029] After the spray ring 15 is sprayed with lubricant, the brush plate 16 located below it is elastically supported by the second spring 20 and slides close to the outer wall of the piston rod as it extends and retracts. The arc design of the brush plate 16 scrapes away impurities adhering to the piston rod surface due to high temperature dust, and evenly coats the lubricant to the entire stroke area. This improves the movement accuracy of the piston rod under high temperature and high dust conditions, reduces maintenance requirements, and ensures the movement trajectory of the moving mold. At the same time, the second spring 20 adjusts the contact pressure between the brush plate 16 and the piston rod in real time to avoid adhesion failure caused by thermal deformation or dust accumulation, and ensures continuous coverage of the lubricating film.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
