Technical Field

[0001] This utility model relates to the field of sports equipment, specifically to a novel football bladder structure and molding die. Background Technology

[0002] As a globally popular sport, the quality and performance of football equipment are crucial to athletes' performance and overall experience. The football bladder, as one of the core components of the football, directly impacts its durability, elasticity, and comfort. Within national standards systems, football bladders must meet specific quality and performance standards to ensure consistent performance in various matches and training sessions.

[0003] As a core component of the soccer ball, the inner bladder's structure directly affects the ball's airtightness, elasticity, and lifespan. Current examinations, tests, competitions, and training place stringent demands on soccer ball performance, requiring the inner bladder to meet indicators such as impact resistance, fatigue resistance, and dimensional stability.

[0004] In existing processes, football bladder production often employs a multi-piece splicing structure, which involves using 8-16 rubber sheets that are hot-pressed or sewn together. The splicing of multiple parts and the use of multiple layers of materials increase the complexity of the production process. The splicing points are prone to wear and cracking, which leads to a decrease in the airtightness and elasticity of the bladder. Moreover, the production process relies on manual cutting and splicing, resulting in a long production cycle, high production costs, and poor dimensional consistency, making it difficult to balance quality and production efficiency.

[0011] A molding die for molding a new type of football bladder structure includes a molding die cover, which consists of a hemispherical mold groove and a fixed edge that is vertically fixed around the top of the outer wall of the mold groove. The fixed edge is provided with an air hole groove that connects the mold groove to the outside.

[0012] In a further embodiment, the inner wall of the mold groove is provided with protrusions corresponding to the groove.

[0013] In a further embodiment, a plurality of bolt holes are evenly provided on the fixed edge.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] I. The football bladder of this utility model is integrally molded from rubber material under high temperature and pressure, which reduces the splicing process and avoids the problems of wear and cracking that are prone to occur at the splicing points in the traditional splicing production process. It enhances the airtightness and durability of the bladder. Moreover, the integral molding production process is simple, the production cycle is short, the production cost is low, and the size of each bladder produced can be kept as consistent as possible, so as to balance production quality and production efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Implementation, for example Figure 1-2As shown, this embodiment provides a novel soccer ball bladder structure, including an inner bladder 1. The inner bladder is integrally formed from 12 T-shaped components 2 that are bonded together. Grooves 3 are provided at the bonding edges of the T-shaped components 2, and one of the T-shaped components has a pre-drilled air nozzle 4. In this embodiment, the soccer ball bladder 1 is integrally formed from rubber material under high temperature and pressure, reducing splicing steps and avoiding problems such as wear and cracking that easily occur at splicing points in traditional splicing production processes. This enhances the airtightness and durability of the inner bladder 1. Moreover, the integral molding production process is simple, has a short production cycle, and low production cost. The dimensions of each produced inner bladder 1 can be kept as consistent as possible, thus balancing production quality and efficiency.

[0023] The novel soccer ball bladder 1 in this embodiment adopts a 12-piece sheet structure design, and the overall shape is three-dimensional, such as... Figure 1 As shown. The inner bladder 1 is made of high-performance rubber material with a special texture and grooves on the surface to enhance airtightness and durability. The edges of the inner bladder 1 are thickened to improve wear resistance. The surface of the inner bladder 1 also features a unique anti-counterfeiting mark, which is ensured by special printing technology or material embedding to guarantee the product's uniqueness and authenticity. In addition, the appearance design of the inner bladder 1 has been carefully optimized, with smooth lines and a reasonable color scheme to enhance its overall aesthetics. The material and surface treatment of the inner bladder 1 have also been specially designed to provide better touch and comfort, making it more comfortable and comfortable for players to use. The internal structure of the inner bladder 1 has been precisely calculated and optimized to ensure that the football maintains a stable shape and elasticity after inflation, thereby optimizing the ball's flight trajectory and improving the effectiveness of tests, matches, and training.

[0024] like Figure 3 As shown, this embodiment also provides a molding die for molding the novel soccer ball inner bladder structure. It consists of two identical molding die covers 5 detachably sealed together. Each molding die cover 5 comprises a hemispherical mold groove 6 and a fixed edge 7 vertically surrounding and fixed to the top of the outer wall of the mold groove 6. The fixed edge 7 has air vents 8 that connect the mold groove 6 to the outside. The inner wall of the hemispherical mold groove 6 has protrusions 9 corresponding to the mold groove 6. The fixed edge 7 has a plurality of bolt holes 10 evenly distributed. In this embodiment, the mold cavity design matches the shape of the inner bladder, thereby ensuring the one-time molding quality of the inner bladder 1. The molding die cover 5 is made of high-strength alloy steel, and its surface is specially treated to improve service life and demolding efficiency. The precise mold cavity design ensures the one-time molding quality of the inner bladder, and the molding structure with anti-counterfeiting markings on the mold surface allows the inner bladder to naturally form unique anti-counterfeiting features during the molding process.

[0025] In use, the rubber material is placed into the mold cavity formed by the engagement of two molding mold covers 5. The upper and lower molding mold covers 5 are then sealed together with bolts. High-pressure gas is introduced into the air nozzle pre-reserved opening 4 on the rubber material within the mold cavity through the air holes formed by the upper and lower air vent grooves 8. The rubber material is vulcanized and molded using high temperature and pressure, allowing the inner liner 1 to be formed in one step, reducing the need for splicing. The special texture and grooves 4 on the surface of the inner liner 1 are formed during the molding process, enhancing its airtightness and durability. Anti-counterfeiting labels are embedded into the surface of the inner liner 1 through the special structure of the mold during molding, ensuring the product's anti-counterfeiting properties. The aesthetics of the inner liner 1 are achieved through a carefully designed appearance and color scheme, while comfort is enhanced through optimized materials and surface treatment.

[0026] Furthermore, in selecting the material for the inner liner, besides high-performance rubber materials, other materials with similar properties, such as thermoplastic elastomers, can be used. For mold materials, in addition to high-strength alloy steel, other high-temperature resistant and high-strength materials, such as cemented carbide, can be used. In terms of molding processes, besides high-temperature and high-pressure vulcanization molding, other suitable molding methods can be employed, such as injection molding. Anti-counterfeiting labels can be implemented through different printing processes or materials, such as laser engraving and electronic chip embedding. The appearance design can be adjusted and optimized according to different market demands and aesthetic trends, employing different line, pattern, and color combinations.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
