[0056] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0057] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0058] Tire flexible mold is a key technical equipment in the tire vulcanization molding process. The mold structure determines its service life and precision.

[0059] The existing tire flexible molds will produce a series of problems during use, such as diameter damage, aluminum sticking, vertical seam damage, etc. Continuing to use the damaged molds will not only cause problems in the produced tires, but also shorten the life of the tire mold itself.

[0060] During the use of tire flexible molds, there is currently no detection method for the mutual force between the caliber and the vertical seam. It can only be inferred theoretically, which makes it difficult to accurately detect or infer the caliber and vertical seam forces, and it is impossible to analyze the root cause of damage to the caliber and vertical seam, nor to measure the deformation stress range of the mold, which is very unfavorable for the optimization design of the mold structure. In response to this problem, the embodiment of the present disclosure provides a method for determining parameters of a tire flexible mold, which is introduced below in conjunction with a specific embodiment.

[0061] Figure 1 A flow chart of a method for determining tire active mold parameters provided in an embodiment of the present disclosure. The method is executed by an electronic device, and the method can be applied to a scenario of detecting the stress of a tire active mold, and can also be applied to a scenario of determining tire active mold parameters. It is understandable that the method for determining tire active mold parameters provided in an embodiment of the present disclosure can also be applied in other scenarios.

[0062] Below Figure 1 The method for determining parameters of the tire active mold shown in the figure is introduced, and the specific steps of the method are as follows:

[0063] S101, performing finite element analysis on a virtual model of a tire flexible mold to obtain stress simulation data of various positions of the virtual model of the tire flexible mold.

[0064] In this step, a virtual model of the tire active mold is constructed in the electronic device. The virtual model of the tire active mold can be a three-dimensional model. The virtual model of the tire active mold is further subjected to finite element analysis to obtain stress simulation data of various positions of the virtual model of the tire active mold. The stress simulation data of various positions include stress simulation data of the caliber, stress simulation data of the vertical seam, and stress simulation data of other positions, which are not specifically limited here.

[0065] S102, obtaining stress test data of a target stress test area of ​​a tire active mold, wherein the target stress test area includes a caliber stress test area and a vertical seam stress test area.

[0066] In this step, the electronic device obtains stress test data of the target stress test area of ​​the tire active mold. Specifically, the electronic device performs actual detection on the tire active mold, such as performing stress detection on the target stress test area of ​​the tire active mold, and obtains stress test data of the target stress test area of ​​the tire active mold. The target stress test area includes a caliber stress test area and a vertical seam stress test area. The caliber stress test area is used to test the stress magnitude of the caliber, and the vertical seam stress test area is used to test the stress magnitude of the vertical seam.

[0067] S103 , determining whether the absolute value of the difference between the stress test data of the target stress test area and the stress simulation data at a position corresponding to the target stress test area is greater than a preset threshold.

[0068] In this step, the electronic device determines whether the absolute value of the difference between the stress test data of the target stress test area and the stress simulation data at the corresponding position of the target stress test area is greater than a preset threshold. Optionally, the electronic device determines whether the difference between the stress test data of the caliber stress test area and the stress simulation data at the corresponding position of the caliber stress test area is greater than a preset threshold of caliber stress, and determines whether the difference between the stress test data of the vertical joint stress test area and the stress simulation data at the corresponding position of the vertical joint stress test area is greater than a preset threshold of vertical joint stress.

[0069] S104. If the absolute value of the difference is less than or equal to a preset threshold, the critical value of the deformation stress data of the tire active mold is determined based on the stress test data of the target stress test area of ​​the tire active deformation mold and the stress test data of the target stress test area of ​​the tire active non-deformed mold.

[0070] In this step, if it is determined that the absolute value of the difference between the stress test data of the target stress test area and the stress simulation data of the corresponding position of the target stress test area is less than or equal to the preset threshold, it can be considered that the stress simulation data is relatively accurate, and the electronic device determines the critical value of the deformation stress data of the tire active mold based on the stress test data of the target stress test area of ​​the tire active deformation mold and the stress test data of the target stress test area of ​​the tire active non-deformed mold. Specifically, the electronic device determines the critical value of the deformation stress data of the tire active mold by measuring the stress test data of the deformed mold and the non-deformed mold multiple times, that is, when the stress test data is below the critical value of the deformation stress data, the mold is not deformed.

[0071] Optionally, the deformation stress data critical value includes the caliber deformation stress data critical value and the vertical seam deformation stress data critical value. The caliber deformation stress data critical value and the vertical seam deformation stress data critical value may be the same or different, and are not specifically limited here.

[0072] In some embodiments, the preset threshold may be an error range. When the absolute value of the difference between the stress test data of the target stress test area and the stress simulation data at the corresponding position of the target stress test area is within the error range, the stress simulation data may be considered to be relatively accurate, and the critical value of the deformation stress data of the tire active mold may be further determined.

[0073] In some embodiments, the method further includes: if the absolute value of the difference is greater than a preset threshold, adjusting mold parameters of the tire active mold virtual model, or adjusting the target stress test area.

[0074] Optionally, if it is determined that the absolute value of the difference between the stress test data of the target stress test area and the stress simulation data at the corresponding position of the target stress test area is greater than a preset threshold, the electronic device adjusts the mold parameters of the tire active mold virtual model, or adjusts the target stress test area, and continues to execute the process of S101~S103 until the absolute value of the difference is less than or equal to the preset threshold, and executes S104.

[0075] The disclosed embodiment performs finite element analysis on the virtual model of the tire active mold to obtain stress simulation data of each position of the virtual model of the tire active mold, obtains stress test data of the target stress test area of ​​the tire active mold, and the target stress test area includes a caliber stress test area and a vertical seam stress test area. It is determined whether the absolute value of the difference between the stress test data of the target stress test area and the stress simulation data of the corresponding position of the target stress test area is greater than a preset threshold value. If the absolute value of the difference is less than or equal to the preset threshold value, the critical value of the deformation stress data of the tire active mold is determined based on the stress test data of the target stress test area of ​​the tire active deformation mold and the stress test data of the target stress test area of ​​the tire active non-deformed mold. Compared with the prior art, the disclosed embodiment can detect the force of the caliber and the vertical seam, further analyze the root cause of the damage of the caliber and the vertical seam, and can calculate the deformation stress range of the mold, so as to apply the deformation stress range to the design process of the mold, predict the possibility of deformation in advance, reduce the probability of deformation during the actual use of the mold, and facilitate the optimization design of the mold structure.

[0076] Figure 2 A flow chart of a method for determining parameters of a tire active mold provided by another embodiment of the present disclosure, such as Figure 2 As shown, the method includes the following steps:

[0077] S201. In response to a user's operation of configuring mold parameters of a virtual model of a tire flexible mold, the mold parameters of the virtual model of the tire flexible mold are acquired.

[0078] In this step, the user may configure the mold parameters of the virtual model of the tire active mold, and the electronic device obtains the mold parameters of the virtual model of the tire active mold in response to the user's operation of configuring the mold parameters of the virtual model of the tire active mold.

[0079] In some embodiments, the mold parameters include caliber parameters of the pattern block and the side panel, vertical seam parameters between the pattern blocks, material parameters, height parameters of the parting surface between the pattern block and the side panel, thickness parameters of the pattern block, and clamping force parameters.

[0080] like Figure 4As shown, the tire flexible mold includes a mounting ring, an upper side plate, an upper cover, an upper steel ring, a tread block, a guide ring, a slider, a base, a lower side plate, and a lower steel ring.

[0081] S202, performing simulation analysis on the virtual model of the tire active mold according to the mold parameters to obtain stress simulation data of various positions of the virtual model of the tire active mold.

[0082] In this step, after obtaining the mold parameters of the tire active mold virtual model, the electronic device simulates and analyzes the tire active mold virtual model according to the mold parameters to obtain stress simulation data of various positions of the tire active mold virtual model.

[0083] S203, determining a target stress test area of ​​the tire active mold.

[0084] In this step, the electronic device determines the target stress test area of ​​the tire active mold.

[0085] In some embodiments, a target stress test area is selected on the tire active mold, and the target stress test area is set on the pattern block. The number of pattern blocks can be selected as a single block or multiple blocks. The number and distribution positions of the target stress test areas can be arranged according to the specific size of the pattern block.

[0086] For example, when one tread block is selected, any tread block on the tire active mold can be selected, preferably the one directly in front; when two tread blocks are selected, two adjacent tread blocks directly in front are preferred, or tread blocks spaced 1 to 3 apart or symmetrically distributed can be selected according to the situation; Figure 5 As shown, radial refers to the direction perpendicular to the arc, and circumferential refers to the direction parallel to the arc. When the number of pattern blocks is 1 or 2, the radial caliber stress test area can be distributed in 3 locations along the radial direction, with an interval of 3mm between each location, the first location is 5~10mm away from the caliber end face, and 3 locations are distributed along the circumferential direction, with uniform size distribution; the circumferential caliber stress test area can be distributed in 3 locations along the radial direction, with an interval of 5mm between each location, the first location is 3~5mm away from the caliber end face, and 5 locations are distributed along the circumferential direction, the left and right locations of the circumference are 2~3mm away from the vertical seam, and the remaining 3 locations are evenly distributed according to size.

[0087] For example, when the number of pattern blocks is 3, three adjacent blocks in the front are preferred, or they are spaced according to the situation; when the number of pattern blocks is 4, four adjacent blocks in the front or evenly distributed circumferentially are preferred. When the number of pattern blocks is 3 or 4, the radial caliber stress test area is distributed at 2 locations along the radial direction, each with an interval of 3 to 5 mm, the first location is 5 to 10 mm away from the caliber end face, and 3 locations are distributed circumferentially, with uniform size distribution; the circumferential caliber stress test area is distributed at 2 locations along the radial direction, each with an interval of 5 mm, the first location is 3 to 5 mm away from the caliber end face, and 3 locations are distributed circumferentially, the left and right locations are 2 to 3 mm away from the vertical seam, and the remaining location is set at the center.

[0088] It should be noted that no matter whether a single or multiple pattern blocks are selected, they can be arranged radially and circumferentially according to the actual size of the pattern blocks to ensure that they are distributed in ≥2 places in the radial direction and ≥3 places in the circumferential direction.

[0089] like Figure 6 As shown, the axial direction is the direction parallel to the vertical seam direction. The vertical seam stress test areas of the tread block can be distributed at three locations along the axial direction, preferably at a position about 3 to 5 mm away from the vertical seam. Among the three test areas, two are close to the shoulder position, and one is located at the center of the tread block. The test areas are symmetrically distributed between the left and right vertical seams.

[0090] S204 , measuring the stress of the target stress test area based on the resistance strain gauge to obtain stress test data of the target stress test area.

[0091] In this step, the electronic device measures the stress of the target stress test area through a resistance strain gauge to obtain stress test data of the target stress test area. Specifically, the resistance strain gauge is pasted at the position of the stress test area to detect the force magnitude at the corresponding position.

[0092] To ensure the use of resistance strain gauges, it is necessary to make a smooth groove in the target stress test area according to the specific size of the tread block. Figure 7 As shown, in the aperture stress test area, the slot depth is 15~20mm, radially across the aperture end face, and the slot width is ≥5 times the size of the resistance strain gauge; in the vertical seam stress test area, the slot is opened from the back of the pattern block to the empty knife of the vertical seam, and the slot width is ≥5 times the size of the resistance strain gauge, and a lead-out slot for the stress test signal line is reserved.

[0093] In order to adapt to the operating conditions of the tire mold, a resistance strain gauge that meets the actual operating temperature conditions can be selected. When selecting the resistance strain gauge patch method, 2 working pieces of a half-bridge are preferred, and 1 working piece of a half-bridge, 4 working pieces of a quarter-bridge and a full-bridge can also be selected.

[0094] The stress test signal line needs to be led out of the mold and connected to the signal receiver. The stress test signal line should not affect the normal opening and closing and vulcanization of the mold when it is led out. The schematic diagram of the pattern block stress test wiring is as follows: Figure 8 shown.

[0095] S205 , determining whether the absolute value of the difference between the stress test data of the target stress test area and the stress simulation data at a position corresponding to the target stress test area is greater than a preset threshold.

[0096] Specifically, the implementation process and principle of S205 and S103 are the same, and will not be repeated here.

[0097] S206. If the absolute value of the difference is less than or equal to a preset threshold, the critical value of the deformation stress data of the tire active mold is determined based on the stress test data of the target stress test area of ​​the tire active deformation mold and the stress test data of the target stress test area of ​​the tire active non-deformed mold.

[0098] Specifically, the implementation process and principle of S206 and S104 are the same, and will not be repeated here.

[0099] S207: If the absolute value of the difference is greater than a preset threshold, adjusting mold parameters of the tire active mold virtual model, or adjusting the target stress test area.

[0100] Optionally, if it is determined that the absolute value of the difference between the stress test data of the target stress test area and the stress simulation data at the corresponding position of the target stress test area is greater than a preset threshold, the electronic device adjusts the mold parameters of the tire active mold virtual model, or adjusts the target stress test area, and continues to execute the process of S201~S205 until the absolute value of the difference is less than or equal to the preset threshold, and executes S207.

[0101] The disclosed embodiment obtains the mold parameters of the virtual model of the tire active mold in response to the user's operation of configuring the mold parameters of the virtual model of the tire active mold, simulates and analyzes the virtual model of the tire active mold according to the mold parameters, and obtains the stress simulation data of each position of the virtual model of the tire active mold. Further, the target stress test area of ​​the tire active mold is determined, and the stress of the target stress test area is measured based on the resistance strain gauge to obtain the stress test data of the target stress test area. It is judged whether the absolute value of the difference between the stress test data of the target stress test area and the stress simulation data of the corresponding position of the target stress test area is greater than the preset threshold. If the absolute value of the difference is less than or equal to the preset threshold, the critical value of the deformation stress data of the tire active mold is determined based on the stress test data of the target stress test area of ​​the tire active deformation mold and the stress test data of the target stress test area of ​​the tire active non-deformed mold; if the absolute value of the difference is greater than the preset threshold, the mold parameters of the virtual model of the tire active mold are adjusted, or the target stress test area is adjusted. Through this method, the stress on the outlet diameter and vertical seam can be detected, the root cause of the damage to the diameter and vertical seam can be further analyzed, the deformation stress range of the mold can be calculated, and the optimization design of the mold structure can be facilitated.

[0125] If the stress simulation data of each position of the adjusted tire active mold virtual model is less than or equal to the critical value of the deformation stress data, it means that the adjusted tire active mold virtual model can meet the stress requirements, and then the target tire active mold is manufactured based on the mold parameters of the adjusted tire active mold virtual model.

Further, it is determined whether the absolute value of the difference between the stress test data of the target stress test area and the stress simulation data of the corresponding position of the target stress test area is greater than a preset threshold value. If the absolute value of the difference is less than or equal to the preset threshold value, the critical value of the deformation stress data of the tire active mold is determined based on the stress test data of the target stress test area of ​​the tire active deformation mold and the stress test data of the target stress test area of ​​the tire active non-deformed mold. Next, the current virtual model of the tire active mold is subjected to finite element analysis to obtain stress simulation data of each position of the current virtual model of the tire active mold, and it is determined whether the stress simulation data of each position of the current virtual model of the tire active mold is greater than the critical value of the deformation stress data. If the stress simulation data of each position of the current tire active mold virtual model is greater than the critical value of the deformation stress data, the mold parameters of the current tire active mold virtual model are adjusted to obtain the adjusted tire active mold virtual model, and the adjusted tire active mold virtual model is subjected to finite element analysis to obtain the stress simulation data of each position of the adjusted tire active mold virtual model. Furthermore, if the stress simulation data of each position of the adjusted tire active mold virtual model is less than or equal to the critical value of the deformation stress data, the target tire active mold is manufactured based on the mold parameters of the adjusted tire active mold virtual model. Compared with the prior art, the disclosed embodiment can detect the force of the caliber and the vertical seam, further analyze the root cause of the damage of the caliber and the vertical seam, calculate the deformation stress range of the mold, and adjust the parameters of the mold so that the stress of each position of the mold is less than or equal to the critical value of the deformation stress data, reduce the probability of deformation of the mold during actual use, and better optimize the mold structure.
