Description

Technical Field

[0001] This utility model belongs to the field of tire molds, and specifically relates to a tire mold temperature measuring cable take-up device, which stores and takes up temperature measuring cables used to measure the temperature of mold tread blocks or tires, so as to achieve temperature measurement while ensuring the sealing of the mold shell. Background Technology

[0002] Temperature control is one of the key factors affecting tire vulcanization quality in the tire vulcanization process. To ensure that the vulcanization temperature accurately meets process requirements, tire manufacturers generally adopt real-time temperature monitoring technology. This involves placing temperature sensing elements inside the tire mold to dynamically monitor temperature parameters during the vulcanization process. This technology not only helps improve the stability of tire vulcanization quality but also improves the tire production traceability system through data collection and analysis, providing data support for process optimization.

[0003] However, with the iterative upgrades of tire mold structures, the traditional temperature sensing wire arrangement method has gradually revealed its technical shortcomings. With the widespread application of vacuum mold shells or fully enclosed mold shells, components such as the mold shell cover, sealing plate, mounting ring, guide ring, and base form a sealed space through sealing rings, fundamentally changing the wiring environment for the temperature sensing wires. For ordinary movable molds, the temperature sensing wires can freely extend and retract through the gap between the mold shell sleeve and the lower base plate. However, in the new sealed structure, the temperature sensing wires must pass through multiple layers of sealing components, and their movement trajectory is strictly limited.

[0004] In existing technologies, the accumulation of temperature sensing wires during the opening and closing process of the arch-shaped seat is a particularly prominent problem. As a core component of the movable mold, the arch-shaped seat's opening and closing action directly drives the mold parting surface movement. When the temperature sensing wire lacks effective constraint, it easily accumulates on the inner side of the arch-shaped seat during mold opening, and may break due to compression or folding during mold closing. To solve this problem, our prior patent CN215511870U proposes two technical solutions:

[0005] 1. Anti-line clamp fixing solution: The temperature measuring line is blocked on the outside of the baffle by the baffle, thus avoiding the temperature measuring line being broken or squeezed by the pattern block. However, this solution causes the temperature measuring line to be in a loose state on the inside of the bow-shaped seat, which cannot adapt to the expansion and contraction with the movement of the mold, and there is still a risk of being squeezed or cut.

[0006] 2. Automatic winding reel solution: The winding reel is driven by a coil spring to wind and unwind the temperature measuring wire. However, due to the lack of a guiding mechanism, the temperature measuring wire is prone to cross-over and entanglement during the winding process, which leads to increased resistance or even jamming during unwinding and cannot meet the dynamic requirements of high-frequency opening and closing of the mold. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a tire mold temperature measuring wire take-up device to solve the problems of easy breakage and entanglement of the temperature measuring wire in the prior art, thereby improving the stability of the temperature measuring device during the tire vulcanization process.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A tire mold temperature measuring wire take-up device includes a mold shell assembly and a cavity assembly disposed within the mold shell assembly. The mold shell assembly includes a middle sleeve, a base, and a top cover. The middle sleeve is provided with a through hole. The cavity assembly includes a plurality of circumferentially arranged tread blocks and an arc-shaped seat disposed on one side of the tread blocks. A temperature measuring element is provided on the side of the tread blocks closer to the tire.

[0010] It also includes at least two sets of guiding mechanisms. The guiding mechanism includes a linear guide rail installed on the side of the bow-shaped seat. A slide block is slidably connected to the linear guide rail. A pulley is rotatably connected to the slide block. The temperature measuring wire of the temperature measuring element passes around the pulley on the slide block in sequence and is led out from the through hole to the outside of the middle sleeve. A fixed rod is provided on one side of the slide block. A tension spring is hung on one side of the fixed rod. The other end of the tension spring is connected to the bow-shaped seat through a tension spring bracket. The tension springs on the side of the adjacent slide block are arranged alternately.

[0011] Furthermore, a sealing connector is provided inside the through hole, and the temperature measuring wire passes through the sealing connector and is sealed before being led out of the middle sleeve.

[0012] Furthermore, the sealing connector is one of a glass sintered connector, a ceramic connector, or a high-temperature sealant connector.

[0013] Furthermore, the sealing connector is interference-fitted or screwed into the through hole.

[0014] Furthermore, the temperature sensing element is a thermocouple or a resistance temperature detector (RTD).

[0015] Furthermore, both ends of the through hole are provided with rounded corners.

[0016] Furthermore, the linear guide is one of a roller linear guide, a cylindrical linear guide, or a ball linear guide.

[0017] Furthermore, an anti-detachment end cap is fixedly connected to one end of the fixing rod.

[0018] The beneficial effects of this utility model are:

[0019] 1) This utility model ensures that the temperature measuring wire is always in a taut state during the mold opening and closing process of the middle sleeve, which solves the problem of the temperature measuring wire being squeezed and broken due to slack in the prior art. At the same time, it avoids the problem of large resistance and jamming caused by the temperature measuring wire crossing and overlapping when winding, thus ensuring the stability of the temperature measuring device during the tire vulcanization process.

[0020] 2) By setting a sealing connector in the through hole, the temperature measuring wire passes through the sealing connector and is sealed before being led out of the middle sleeve, which ensures the vacuuming effect during tire vulcanization and the temperature measurement of the mold under high pressure sealing effect.

[0021] 3) Rounded corners with a radius not less than twice the diameter of the temperature measuring wire are set at both ends of the through hole to prevent the temperature measuring wire from being cut by the end of the through hole during the mold opening and closing process, thus extending the service life of the temperature measuring wire.

[0022] 4) By setting an anti-detachment end cap at the end of the fixed rod, the tension spring is prevented from slipping off the end of the fixed rod, thus ensuring the stability of the winding device. Attached Figure Description

Detailed Implementation

[0029] The following will be combined with the appendix Figures 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] like Figure 1 , Figure 2 As shown, a tire mold temperature measuring wire take-up device includes a mold shell assembly and a cavity assembly disposed within the mold shell assembly. The mold shell assembly includes a middle sleeve 2, a base 1, and a top cover. The middle sleeve 2 is provided with a through hole 3. The cavity assembly includes a plurality of circumferentially arranged tread blocks 7 and an arc-shaped seat 6 disposed on one side of the tread blocks 7. A temperature measuring element 9 is provided on the side of the tread blocks 7 near the tire 8. The mold shell assembly and the cavity assembly are common components of tire molds and will not be described in detail here.

[0032] It also includes at least two sets of guiding mechanisms, such as Figures 3-5 As shown, the guiding mechanism includes linear guide rails 10 mounted on the side of the bow-shaped seat 6 (the side of the bow-shaped seat 6 refers to the mating surface of two adjacent bow-shaped seats 6). The number of linear guide rails 10 is determined according to the displacement of the middle sleeve 2 during mold opening, such as... Figure 4 , Figure 5 As shown, a slide block 11 is slidably connected to the linear guide rail 10, and a pulley 12 is rotatably connected to the slide block 11. The temperature measuring wire 5 of the temperature measuring element 9 passes around the pulley 12 on the slide block 11 and is led out from the through hole 3 to the outside of the middle sleeve 2. A fixing rod 17 is provided on one side of the slide block 11, and a tension spring 13 is hung on one side of the fixing rod 17. The other end of the tension spring 13 is connected to the bow-shaped seat 6 through the tension spring bracket 14. The tension springs 13 on the adjacent slide blocks 11 are arranged alternately up and down.

[0033] After the middle sleeve 2 is closed, the tension spring 13 exerts a certain initial preload on the slide block 11. This preload keeps the temperature measuring wire 5 on the winding pulley 12 in a taut state. When the middle sleeve 2 is opened, the middle sleeve 2 moves upward, pulling the temperature measuring wire 5 upward. The temperature measuring wire 5 drives the slide block 11 to move on the linear guide rail 10, the tension spring 13 is stretched, and multiple slide blocks 11 move closer to each other. At this time, the temperature measuring wire 5 is also in a taut state. Therefore, whether the mold is opened or closed, the temperature measuring wire 5 is always in a taut state, which solves the problem of the temperature measuring wire 5 being squeezed and broken due to slack in the prior art. At the same time, it avoids the problem of the temperature measuring wire 5 crossing and overlapping during winding, resulting in high resistance and jamming during the release of the temperature measuring wire 5, and ensures the stability of the temperature measuring device during the tire vulcanization process.

[0034] like Figure 1 , Figure 2 As shown, a sealing connector 4 is provided inside the through hole 3. The temperature measuring wire 5 passes through the sealing connector 4 and is sealed before being led out of the middle sleeve 2, which ensures the vacuuming effect during tire vulcanization and the temperature measurement of the mold under high pressure sealing effect.

[0035] The sealing connector 4 is one of a glass sintered connector, a ceramic connector, or a high-temperature sealant connector. The temperature measuring wire 5 is passed through the sealing connector 4, which ensures the sealing of the mold housing assembly while realizing the transmission of the temperature measuring signal.

[0036] As a further preferred embodiment, the sealing connector 4 is interference-fitted or screwed to the through hole 3, which facilitates the installation of the sealing connector 4.

[0037] The temperature sensing element 9 is a thermocouple or a resistance temperature detector (RTD).

[0038] like Figure 2 As shown, both ends of the through hole 3 are provided with rounded corners 15, which avoids the temperature measuring wire 5 being cut by the end of the through hole 3 during the mold opening and closing process, and extends the service life of the temperature measuring wire 5.

[0039] The linear guide 10 is one of a roller linear guide, a cylindrical linear guide, or a ball linear guide.

[0040] like Figure 4 As shown, one end of the fixing rod 17 is fixedly connected to an anti-detachment end cap 16, which prevents the tension spring 13 from slipping off the end of the fixing rod 17.

[0041] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
