Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a golf ball glue injection channel. Background Technology

[0002] In the manufacturing process of golf balls, especially in the injection molding of the core and outer layer, the precise and uniform filling of the rubber compound (such as polybutadiene rubber) is crucial to the performance of the final product. Golf balls need to have highly consistent elasticity, weight, and structure to ensure that the ball's flight distance, trajectory, and stability meet requirements. However, existing injection channel designs, especially when using multi-cavity molds to improve production efficiency, often face a key technical challenge: how to ensure that the molten rubber can be uniformly and synchronously distributed and fill all mold cavities.

[0003] Traditional flow distribution designs, such as simple single-stage flow distribution or asymmetric flow distribution, can easily lead to pressure and velocity differences in the rubber compound as it flows along different paths. Cavities closer to the main feed inlet tend to be filled first and at higher pressure, while cavities further away are filled later and at lower pressure. This uneven filling results in significant differences in density distribution, overall weight, and internal structure among golf balls produced from different cavities. These differences not only affect the performance of individual balls (such as roll deviation and inconsistent flight distance) but also cause quality fluctuations in the entire batch, increasing the defect rate.

[0004] Therefore, there is an urgent need to develop a new type of golf ball glue injection channel structure that can effectively solve the problem of uniform flow distribution during the glue injection process of multi-cavity molds, and ensure that each cavity receives an equal amount, equal pressure and synchronous supply of glue, thereby producing golf balls with highly consistent performance. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a golf ball injection channel. The rubber compound is injected through a main delivery channel, then distributed through a distribution channel, and sequentially enters a first, second, and third equalization channel. Symmetrical distribution is achieved through at least two oppositely positioned distribution outlets. The coordinated use of the first, second, and third equalization channels effectively eliminates the pressure and velocity differences caused by traditional distribution methods, ensuring that the rubber compound is injected into all mold cavities in equal quantity, pressure, and synchronously. This solves the problem of uneven filling, thereby guaranteeing a high degree of consistency in the density distribution, overall weight, and internal structure of the golf balls, improving product performance and batch stability.

[0006] To achieve the above objectives, the present invention provides a golf ball glue injection channel, comprising a main conveying channel, a branch conveying channel, a first material equalization channel, a second material equalization channel, and a third material equalization channel;

[0007] The main conveying channel, the diversion conveying channel, the first material equalization channel, the second material equalization channel, and the third material equalization channel are connected to each other;

[0036] The present invention will now be described in detail with reference to the accompanying drawings.

[0037] like Figure 1 and Figure 2 As shown, the present invention provides a golf ball glue injection channel, which includes a main conveying channel 1, a branch conveying channel 2, a first material equalization channel 3, a second material equalization channel 4, and a third material equalization channel 5.

[0038] The main conveying channel 1, the branch conveying channel 2, the first material equalization channel 3, the second material equalization channel 4, and the third material equalization channel 5 are interconnected. This multi-stage interconnected structural design guides and distributes the molten rubber step by step. It effectively solves the problem of uniform flow distribution during the injection process in multi-cavity molds, ensuring that each cavity receives an equal amount, equal pressure, and synchronous supply of rubber, thereby producing golf balls with highly consistent performance and reducing quality fluctuations and defect rates in the entire batch.

[0039] The first material distribution channel 3 is provided with at least two branch outlets 31, which are arranged opposite to each other. The oppositely arranged branch outlets 31 can make the material more evenly distributed in space when flowing out, reducing uneven filling caused by differences in direction. This helps to achieve a more uniform distribution of the material in the initial branching stage, avoiding the material from flowing in one direction, and laying the foundation for uniform filling of the mold cavity in the subsequent process.

[0040] The second uniform flow channel 4 is located inside the first uniform flow channel 3; it can further converge and redistribute the rubber material diverted from the first uniform flow channel 3, and change the flow path and state of the rubber material by adjusting its spatial position. This further homogenizes the rubber material during the flow process, reduces the pressure difference and flow velocity difference of the rubber material on different paths, and ensures the uniformity of rubber material distribution.

[0041] The third material distribution channel 5 is located inside the second material distribution channel 4 and connects to the mold cavity. After the two-stage material distribution and homogenization process of the first material distribution channel 3 and the second material distribution channel 4, the third material distribution channel 5 precisely delivers the rubber material into the mold cavity, ensuring that the rubber material enters the cavity directly from a uniformly distributed state. This ensures that each cavity receives an equal amount, equal pressure, and synchronous supply of rubber material, resulting in golf balls produced from different cavities exhibiting high consistency in density distribution, overall weight, and internal structure, thus improving the performance of individual balls (such as reducing roll deviation and ensuring consistent flight distance).

[0042] During operation, the molten rubber is first injected into the main conveying channel 1; the rubber enters the branch conveying channel 2 from the main conveying channel 1 and is guided to the first equalization channel 3, completing the initial branching guidance; the rubber flows into the first equalization channel 3, which simultaneously and symmetrically outputs the rubber to both sides (or corresponding directions) through at least two oppositely arranged branch outlets 31, achieving an initial balanced distribution of flow rate and pressure, completing the first stage of symmetrical equalization; the rubber flowing out of the branch outlets 31 of the first equalization channel 3 enters the second equalization channel. 4; The second uniform material flow channel 4 receives the uniform rubber material from both sides, performs further mixing and pressure balancing, and completes the second-stage progressive uniform material distribution; the rubber material flows from the second uniform material flow channel 4 into the third uniform material flow channel 5; the third uniform material flow channel 5 completes the final uniform material distribution process, and the third-stage final uniform material is injected into the mold cavity; the rubber material that has been uniformly distributed through the first uniform material flow channel 3, the second uniform material flow channel 4 and the third uniform material flow channel 5 is directly and synchronously injected into the mold cavity of each mold through the third uniform material flow channel 5, ensuring that each cavity is filled with equal amount, equal pressure and synchronously.

[0043] like Figure 1 As shown, in this embodiment, the diversion conveying channel 2 is vertically connected to the output end of the main conveying channel 1. This optimizes the transition path of the rubber compound from the main conveying channel 1 to the diversion conveying channel 2, reducing abrupt changes in flow direction and resistance. This helps the subsequent first equalization channel 3, second equalization channel 4, and third equalization channel 5 to receive the rubber compound more evenly, thereby alleviating the problem of asynchronous cavity filling caused by uneven flow (such as delayed filling and lower pressure in the distal cavity), and improving the density distribution and structural consistency of the golf balls.

[0044] like Figure 2 As shown, the diversion conveying channel 2 in this embodiment includes a first diversion channel 21 and a second diversion channel 22. The first diversion channel 21 is connected to the main conveying channel 1 and receives the adhesive material from the main conveying channel 1. This achieves a smooth transition and initial distribution of the adhesive material from the main conveying channel 1 to the interior of the diversion conveying channel 2, laying the foundation for subsequent diversion.

[0045] The second branch channel 22 is vertically connected to the output end of the first branch channel 21. The vertical connection structure optimizes the flow path of the rubber material from the first branch channel 21 into the second branch channel 22, reduces turbulence and pressure loss caused by abrupt changes in flow direction, and helps maintain a more stable flow rate and pressure. This allows the rubber material to enter the downstream first uniform flow channel 3, second uniform flow channel 4, and third uniform flow channel 5 more evenly, thereby improving the synchronization and uniformity of filling each mold cavity and enhancing the consistency of golf ball products.

[0046] like Figure 2 As shown, the first material distribution channel 3 in this embodiment includes a collection section 32, a first diversion section 33, and a second diversion section 34;

[0047] The collecting section 32 is connected in parallel to the output end of the diversion and conveying channel 2, forming a horizontal transition channel. It receives and temporarily collects the rubber material from the diversion and conveying channel 2, reducing abrupt changes in flow direction, lowering initial pressure loss, and providing a stable source of rubber material for subsequent diversion.

[0048] The first branch section 33 is inclinedly connected to the output end of the converging section 32, forming the first gradual change in the flow direction. The inclined transition guides the flow of the rubber compound, reduces turbulence and resistance, initially optimizes the rubber compound distribution path, and improves the uniformity of flow velocity.

[0049] The second diversion section 34 is inclinedly connected to the output end of the first diversion section 33, forming a secondary directional gradient. Through the continuous inclined connection design, the flow path of the rubber material is further smoothed, and the first diversion section 33 works together to achieve a more balanced flow distribution. This ensures that the pressure and flow rate of the rubber material output through the diversion outlet 31 of the second diversion section 34 are more consistent, thereby improving the synchronization and uniformity of filling in each mold cavity and solving the problems of filling lag and structural differences.

[0050] like Figure 2 As shown, in this embodiment, the angle between the first diversion section 33 and the converging section 32 is smaller than the angle between the second diversion section 34 and the first diversion section 33. The first diversion section 33 is connected to the output end of the converging section 32 at a relatively small inclination angle, forming a gentler initial flow direction change. The smaller angle between them makes the change in direction of the rubber material flowing from the converging section 32 into the first diversion section 33 more gradual, significantly reducing flow resistance and pressure loss.

[0051] The second diversion section 34 is connected to the output end of the first diversion section 33 at a relatively large angle, forming a more significant secondary flow direction adjustment. After the rubber compound has been initially stabilized by the first diversion section 33, the larger angle between them can more effectively guide the rubber compound to the target area, optimize the distribution path, and work together with the first diversion section 33 to ensure the balance of pressure and flow rate of the rubber compound at the diversion outlet 31.

[0052] like Figure 2 As shown, in this embodiment, multiple connecting channels 6 are provided between the third uniform material flow channel 5 and the second uniform material flow channel 4. These multiple channels disperse the flow resistance of the rubber compound, significantly reducing pressure loss caused by path differences. When the local flow resistance of the third uniform material flow channel 5 fluctuates, the rubber compound is automatically replenished through other connecting channels 6, ensuring that the pressure at each inlet of the third uniform material flow channel 5 tends to be the same. Combined with the graded uniform material distribution effect of the first uniform material flow channel 3 and the second uniform material flow channel 4, this further eliminates filling lag, ensuring that all mold cavities receive equal pressure and equal amount of rubber compound, improving the density and structural consistency of the golf ball.

[0053] like Figure 2As shown, in this embodiment, the diversion outlet 31 is staggered with the multiple connecting channels 6. This avoids direct collision or overlap of the rubber flow paths. It also prevents turbulent flow between the rubber flowing out of the diversion outlet 31 and the rubber flowing in the connecting channels 6, ensuring more uniform pressure transmission of the rubber in the second uniform flow channel 4 and the third uniform flow channel 5.

[0054] like Figure 2 As shown, the connecting channel 6 in this embodiment includes an inlet section 61 and an outlet section 62, which are connected. The inlet section 61 is connected to the second material equalization channel 4, and the outlet section 62 is connected to the third material equalization channel 5. This enables the connecting channel 6 to be connected between the second material equalization channel 4 and the third material equalization channel 5.

[0055] The flow cross-sectional area of ​​the inlet section 61 is smaller than that of the outlet section 62. By reducing the flow cross-sectional area of ​​the inlet section 61, the flow velocity of the rubber compound increases and the pressure decreases when it enters the connecting channel 6; subsequently, the flow cross-sectional area of ​​the outlet section 62 expands, the flow velocity decreases and the pressure recovers. The "diffuser" effect is used to offset the pressure loss caused by flow resistance. This ensures that the rubber compound flows from the outlet section 62 into the third uniform flow channel 5 with a more stable pressure.

[0056] like Figure 2 As shown, in this embodiment, multiple injection ports 51 are evenly arranged between the third material distribution channel 5 and the mold cavity. The multiple injection ports 51 are distributed at equal intervals or symmetrically to avoid uneven pressure distribution in the cavity caused by concentrated injection of glue at a single inlet. Each cavity is injected with glue simultaneously through multiple injection ports 51, which significantly shortens the filling time difference and overcomes the filling lag in the far-end area.

[0057] like Figure 2 As shown, in this embodiment, the cross-sectional areas of the main conveying channel 1, the branch conveying channel 2, the first equalizing channel 3, the second equalizing channel 4, and the third equalizing channel 5 are progressively smaller. Through this progressively smaller cross-sectional area design, the flow velocity of the rubber compound gradually increases during flow, avoiding velocity attenuation due to path lengthening. The reduced cross-sectional area compensates for pressure loss caused by flow resistance, ensuring the rubber compound maintains relatively stable pressure after flowing through each channel. This ensures that the rubber compound is ultimately injected into all mold cavities in an equal quantity and at equal pressure.

[0058] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
