Description

Technical Field

[0001] The utility model relates to the technical field of tire molds, and particularly relates to an improved structure of a steel sheet of a tire mold. Background Art

[0002] In the design of snow tires, the hardness of the tread rubber and the tread pattern structure are the key factors affecting the tire performance. In order to provide good grip and adapt to the snow environment, traditional snow tires usually adopt a lower hardness tread rubber and are designed with complex fine tread grooves. These grooves not only help with drainage and increase the contact area with the snow, but also provide the necessary traction force.

[0003] However, this design also brings a significant problem: the tread rubber is divided into narrow and elongated strip shapes, and these strip-shaped rubbers are only connected to the tread by their roots. In the indoor drum test, this structure exposes a serious drawback - due to the continuous friction during tire rotation, the roots of the elongated strip-shaped rubbers are prone to breakage due to insufficient breaking strength, which easily leads to the detachment of the tread rubber blocks. This phenomenon not only affects the service life of the tire, but also may endanger driving safety.

[0004] The present utility model is studied and proposed in view of the deficiencies of the prior art. Summary of the Utility Model

[0005] Aiming at the technical problem that the roots of the elongated strip-shaped rubbers on the tread of the existing snow tires are prone to breakage due to insufficient breaking strength, which easily leads to the detachment of the tread rubber blocks.

[0006] The technical solution adopted by the present utility model to solve its technical problems is:

[0007] An improved structure of a steel sheet of a tire mold, comprising: a pattern steel sheet and two pattern groove blocks. The pattern steel sheet is located between the two pattern groove blocks, and each of the pattern groove blocks is arranged at intervals with the pattern steel sheet. A slot is opened at the bottom of the pattern steel sheet.

[0008] For the improved structure of a steel sheet of a tire mold as described above, the slot is in a U shape.

[0009] For the improved structure of a steel sheet of a tire mold as described above, the length dimension of the pattern groove block is A, and the length of the pattern steel sheet is B, where A and B satisfy: 0.7A ≤ B ≤ 0.85A.

[0010] For the improved structure of a steel sheet of a tire mold as described above, the length dimension of the pattern groove block is A, and the depth of the slot is C, where A and C satisfy: 0.45A ≤ C ≤ 0.55A.

[0011] An improved structure of the steel sheet of a tire mold as described above, the width of the pattern steel sheet is D, and the width of the slot is d, where D and d satisfy: 0.25D ≤ d ≤ 0.35D.

[0012] An improved structure of the steel sheet of a tire mold as described above, the slot is located in the middle area of the pattern steel sheet.

[0013] An improved structure of the steel sheet of a tire mold as described above, there are bosses provided on the side walls of the pattern steel sheet.

[0014] An improved structure of the steel sheet of a tire mold as described above, the bosses are arranged corresponding to the slots, and the bosses are located above the slots.

[0016] An improved structure of the steel sheet of a tire mold as described above, the bottom of the bosses is close to the top of the slots.

[0017] The beneficial effects of the present utility model are:

[0018] An improved structure of the steel sheet of a tire mold of the present utility model includes: a pattern steel sheet and two pattern groove blocks. The pattern steel sheet is located between the two pattern groove blocks, and each of the pattern groove blocks is arranged at an interval from the pattern steel sheet. Slots are provided at the bottom of the pattern steel sheet. With such a design, the roots of adjacent strip-shaped rubbers can be interconnected, thereby forming a more stable connection network. This connectivity enhances the tear resistance of the roots of the rubber blocks, and even under extreme driving conditions, the integrity of the rubber blocks can be maintained.

This structure is not only applicable to snow tires but can also be extended to other types of tire designs to improve the durability and reliability of the tires.

[0019] Next, the present utility model will be further described in conjunction with the drawings and specific embodiments. Description of the Drawings

[0020] Figure 1 It is one of the front views of the present utility model;

[0021] Figure 2 It is the second front view of the present utility model;

[0022] Figure 3 It is the top view of the present utility model. Specific Embodiments

[0023] The following will describe in detail the embodiments of the present utility model in conjunction with the accompanying drawings.

[0024] As Figures 1 to 3 shown, an improved structure of a steel sheet of a tire mold in this embodiment includes: a pattern steel sheet 1 and two pattern groove blocks 2. The pattern steel sheet 1 is located between the two pattern groove blocks 2, and each of the pattern groove blocks 2 is arranged at an interval from the pattern steel sheet 1. A slot 3 is opened at the bottom of the pattern steel sheet 1. With such a design, the roots of adjacent strip-shaped rubbers can be interconnected, thereby forming a more stable connection network. This connectivity enhances the tear resistance of the roots of the rubber blocks, and even under extreme driving conditions, the integrity of the rubber blocks can be maintained. Through the above improvements, the problem that the tread rubber blocks of traditional snow tires are prone to falling off is effectively solved, and the overall performance and safety of the tires are improved. This structure is not only applicable to snow tires but can also be extended to other types of tire designs to improve the durability and reliability of the tires.

[0025] As Figures 1 to 3 shown, the slot 3 in this embodiment is in a U shape. Preferably, the U-shaped slot design provides a larger contact area, enabling the roots of the rubber blocks to be more firmly connected. Compared with slots of other shapes, the U-shaped design can more effectively disperse stress and reduce the risk of tearing and falling off of the rubber blocks during use.

[0026] Furthermore, the shape of the U-shaped groove provides more stable structural support, enabling the root connection part of the formed rubber to ensure that the rubber blocks will not easily move or deform when subjected to external forces. This stability helps to maintain the consistency of the tread pattern, thereby improving the grip and handling performance of the tires.

[0027] Furthermore, the U-shaped groove design is relatively simple and easy to implement in the manufacturing process. This design not only reduces the production difficulty but also reduces the production cost. The standardized shape of the U-shaped groove also helps to improve the production efficiency and product consistency.

[0028] Furthermore, the structural design of the U-shaped groove makes the roots of the rubber blocks more firm and not easily worn and torn. This not only extends the service life of the rubber blocks but also reduces the need for frequent tire replacement, thereby reducing the usage cost.

[0029] As Figures 1 to 3 shown, the length dimension of the pattern groove block 2 in this embodiment is A, and the length of the pattern steel sheet 1 is B, where A and B satisfy: 0.7A ≤ B ≤ 0.85A.

[0030] Specifically, the pattern steel sheet 1 is the core part of the improved structure, and the length B of the pattern steel sheet 1 satisfies 0.7A≤B≤0.85A. This design ensures the reasonable coordination between the pattern steel sheet 1 and the pattern groove block 2. Moreover, such a design can ensure the volume of the pattern steel sheet 1, ensure that it still has sufficient structural strength after grooving, and ensure the groove depth of the pattern steel sheet 1 to the tire surface.

[0031] Preferably, the length B of the patterned steel sheet 1 of this embodiment is 0.8A.

[0032] like Figures 1 to 3 As shown, the length dimension of the pattern groove block 2 of this embodiment is A, and the depth of the groove 3 is C, wherein A and C satisfy: 0.45A≤C≤0.55A. Such a design can ensure that the rubber formed by the groove 3 has sufficient thickness, ensuring its service life, and will not break due to thin thickness.

[0033] Preferably, in this embodiment, the depth C of the groove 3 is 0.8A.

[0034] like Figures 1 to 3 As shown, the width of the patterned steel sheet 1 of this embodiment is D, and the width of the groove 3 is d, wherein D and d satisfy: 0.25D≤d≤0.35D. Such a design can ensure that sufficient rubber thickness is retained on both sides of the rubber block, thereby providing the necessary mechanical strength. This rubber distribution helps to resist damage caused by external forces and environmental factors (such as temperature changes, humidity, etc.) and reduce the risk of cracks and fractures.

[0035] Preferably, in this embodiment, the width d of the slot 3 is 0.3D.

[0036] Preferably, the groove 3 of this embodiment is located in the middle area of ​​the patterned steel sheet 1. Placing the groove in the middle area of ​​the patterned steel sheet can ensure that the thickness of the rubber on both sides is equal, which helps to maintain the strength and stability of the rubber. The uniform thickness can prevent one side from being too thin and easy to break, and also avoid one side from being too thick and unnecessarily increasing the weight of the tire.

[0037] like Figures 1 to 3 As shown, a boss 4 is provided on the side wall of the patterned steel sheet 1 of this embodiment. With such a design, a cavity is formed in the tread rubber block. Specifically, the cavity formed by the boss in the rubber block can play a role in buffering and dispersing pressure. The space inside the cavity allows the rubber block to have a certain deformation space when subjected to force, thereby avoiding local stress concentration and reducing fatigue and damage to the rubber block. In addition, the cavity design can increase the flexibility of the rubber block, so that it can better fit and deform when contacting the road surface, thereby providing a larger ground contact area and a more uniform pressure distribution, and increasing the strength of the middle part of the tread rubber block.

[0038] Preferably, the combined design of the cavities enables the rubber blocks to dynamically adjust the contact area with the ground during driving. When the tire rolls, the cavity parts of the rubber blocks can slightly deform under pressure, allowing the rubber blocks to form a larger contact area with the road surface, thereby improving the grip and stability.

[0039] As Figures 1 to 3 shown, the boss 4 of this embodiment is arranged corresponding to the slot 3. The boss 4 is located above the slot 3, that is, the cavity formed by the boss in the rubber block is located above the connection of the adjacent strip-shaped rubber roots formed by the slot 3.

[0040] Specifically, since the cavity of the boss is located above the root connection, it can provide a buffer area between the rubber blocks, which helps to evenly distribute the pressure from the road surface and extend the service life of the rubber root connection and the rubber blocks.

[0041] As Figures 1 to 3 shown, the width of the boss 4 of this embodiment is greater than the width of the slot 3. With such a design, sufficient deformation space is provided for the rubber blocks.

[0042] As Figures 1 to 3 shown, the bottom of the boss 4 of this embodiment is close to the top of the slot 3, that is, the bottom of the cavity formed by the boss in the rubber block is close to the top of the connection of the adjacent strip-shaped rubber roots formed by the slot 3, ensuring sufficient deformation space for the rubber root connection.

[0043] The above only uses embodiments to further illustrate the technical content of the present invention to make it easier for readers to understand, but it does not mean that the implementation modes of the present invention are limited to this. Any technical extension or re-creation based on the present invention is protected by the present invention. The protection scope of the present invention is subject to the claims.
