Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and in particular to a precision cutting mold for football skin. Background Technology

[0002] In the early days of football production, the outer skin of footballs was mostly cut by hand. Workers used scissors or simple knives to cut the leather. This method was extremely inefficient, and the cutting accuracy depended entirely on the worker's manual skills and experience. It was difficult to ensure that the shape and size of each piece of skin were consistent, resulting in inconsistent quality of footballs and production efficiency that could not meet the needs of large-scale production.

[0003] The existing IMG forming skin mold is mainly composed of an upper mold and a lower mold. The lower mold is mainly composed of a nickel shell mold and an outer box plate, while the upper mold is mainly composed of an aluminum mold core and support columns. In the entire process, the heated skin is formed by the upper and lower molds working together and vacuuming. After the skin is formed, it is taken out as a whole, and the edges are trimmed by the subsequent process. Since the skin cannot be directly trimmed after the mold is processed, another process is required for trimming, which increases labor time and other equipment investment, and also increases manufacturing costs.

[0004] The existing patent (publication number: CN216466132U) for a skin forming mold with a cutting structure integrates the cutting structure into the forming mold, enabling the skin periphery to be cut while the mold is closed. This eliminates the need for additional manpower and equipment, making the entire operation more convenient and effectively reducing costs.

[0005] To address the aforementioned issues, existing patents offer solutions. Existing precision cutting molds for soccer ball skins typically involve manually cleaning residual debris and waste from the cutting process. However, it is inconvenient to remove debris and waste adhering to the mold surface, which can affect the mold's shape stability. Furthermore, these molds are not suitable for adapting to soccer ball skins of different sizes and shapes, resulting in inaccurate positioning of the soccer ball skin within the mold and impacting the precision and quality of subsequent cutting.

[0006] To address this, a precision cutting mold for soccer ball skin is proposed. Utility Model Content

However, it is not convenient to remove debris and waste adhering to the mold surface, which can affect the shape stability of the mold. Furthermore, it is not convenient to adapt to soccer ball skins of different sizes and shapes, resulting in inaccurate positioning of the soccer ball skin in the mold and affecting the accuracy and quality of subsequent cutting.

[0026] 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A precision cutting mold for soccer ball skin includes a base 1, a cleaning component 4 disposed on the outer side of the base 1, and a limiting component 5 disposed on the top of the base 1;

[0029] The cleaning component 4 includes a first side plate 401 bolted to the right side of the base 1. A first hydraulic cylinder 402 is bolted to the right side of the first side plate 401. A dust suction plate 403 is bolted to the output end of the first hydraulic cylinder 402. A connecting hose 404 is connected to the top of the dust suction plate 403. A vacuum cleaner 405 is connected to the bottom of the connecting hose 404. The vacuum cleaner 405 is bolted to the first side plate 401. A second side plate 406 is bolted to the left side of the base 1. A second hydraulic cylinder 407 is bolted to the left side of the second side plate 406. A top plate 408 is fixedly connected to the output end of the second hydraulic cylinder 407. A cylinder 409 is bolted to the top of the top plate 408. An electric rotating brush machine 410 is bolted to the output end of the cylinder 409.

[0030] In this embodiment: By activating the second hydraulic cylinder 407, and then receiving the start signal, the internal hydraulic system of the second hydraulic cylinder 407 drives the piston to move, causing the output end to extend, so that the top plate 408 moves smoothly with the extension of the second hydraulic cylinder 407. When the top plate 408 moves precisely to the designated position on the top of the lower mold base 501, the cylinder 409 is then activated. The air pressure in the cylinder 409 pushes the piston, causing the output end of the cylinder 409 to produce a linear displacement, driving the electric rotary brush machine 410 to move downward along a preset path until it smoothly enters the lower mold base 501. Then, the motor built into the electric rotary brush machine 410 runs at high speed, driving the brush head to rotate at a high speed. During the rotation, the bristles fully contact the internal surface and gaps of the lower mold base 501. Then, through the strong centrifugal force and friction generated by the high-speed rotation of the bristles, various debris and waste materials attached to the mold surface are effectively removed, causing them to detach from the mold surface. After the electric rotary brush machine 410 completes the process of cleaning the lower mold base 501, the brush head moves downward along a preset path until it smoothly enters the lower mold base 501. After the internal cleaning task is completed, the output end is retracted by the second hydraulic cylinder 407. Under the reverse action of the hydraulic system, the top plate 408 drives the electric rotary brush machine 410 back to the initial position along the original path to facilitate subsequent dust collection. Then, the first hydraulic cylinder 402 is started, and its output end is extended to push the dust collection plate 403 forward. The thin plate can then generate negative pressure on the area on the top of the lower mold base 501 that has been cleaned by the electric rotary brush machine 410 for suction cleaning. Under the action of negative pressure, the waste material that has been loosened by the electric rotary brush machine 410 on the lower mold base 501 is sucked into the connecting hose 404 through the dust collection hole of the dust collection plate 403. The waste material is transported into the dust collection box inside the vacuum cleaner 405 by the airflow in the connecting hose 404 for collection, so as to achieve efficient cleaning of the football skin cutting mold, ensure that the mold maintains a good working condition in subsequent work, and improve the accuracy and quality of football skin cutting.

[0031] Specifically, such as Figure 3 , Figure 5As shown, the limiting component 5 includes a lower mold base 501 bolted to the top of the base 1. A limiting frame 502 is bolted to the inner side of the lower mold base 501. Adjustable hydraulic cylinders 503 are bolted to both sides inside the limiting frame 502.

[0032] Specifically, such as Figure 3 , Figure 5 As shown, the output end of the adjusting hydraulic cylinder 503 is fixedly connected to a limit plate 504, and the bottom of the limit plate 504 is fixedly connected to a limit spring 505.

[0033] Specifically, such as Figure 3 , Figure 5 As shown, a fixing plate 506 is fixedly connected to the bottom of the limiting spring 505, and a rubber buffer pad 507 is embedded in the bottom of the fixing plate 506.

[0034] In this embodiment: by activating the adjusting hydraulic cylinder 503, the adjusting hydraulic cylinder 503 drives the limiting plate 504 to move according to the size and shape of the football skin. Then, the limiting spring 505 at the bottom of the limiting plate 504 and the rubber buffer pad 507 on the fixing plate 506 can provide cushioning to avoid damage to the football skin, while ensuring a tight fit to the skin and stable positioning. The sliding block 3 on the outer side of the limiting plate 504 is slidably connected to the lower mold base 501 to ensure the smoothness and accuracy of the movement of the limiting plate 504, so that the position of the football skin in the horizontal direction is accurately fixed.

[0035] Specifically, such as Figure 1 , Figure 4 As shown, a support rod 6 is bolted to the top of the base 1, a top seat 7 is bolted to the top of the support rod 6, a hydraulic cylinder 8 is bolted to the top of the top seat 7, and a pressure sensor 9 is provided on the outside of the hydraulic cylinder 8.

[0036] Specifically, such as Figure 4 As shown, the output end of the hydraulic cylinder 8 is fixedly connected to the upper mold base 10, the top of the upper mold base 10 is movably connected to the guide rod 11, and the bottom of the guide rod 11 is bolted to the lower mold base 501.

[0037] In this embodiment: by setting up a support rod 6, a top seat 7, a hydraulic cylinder 8, and a pressure sensor 9, when a cutting operation is required, the control system starts the hydraulic cylinder 8, which then pushes the piston to move, thereby driving the upper mold seat 10 to move downward. At the same time, the pressure sensor 9 monitors the pressure change outside the hydraulic cylinder 8 in real time and transmits it to the control system. Then, the control system adjusts the flow rate and pressure of the hydraulic oil to ensure that the pressure of the upper mold seat 10 is stable during the downward process and meets the requirements for cutting the football skin. By setting up the upper mold seat 10 and the guide rod 11, during the up and down movement of the upper mold seat 10 driven by the hydraulic cylinder 8, the upper mold seat 10 moves smoothly along the axial direction of the guide rod 11. The guide rod 11 restricts the movement direction of the upper mold seat 10 to prevent the upper mold seat 10 from deviating, shaking, or tilting during the movement.

[0038] Specifically, such as Figure 1 As shown, an anti-slip pad 2 is bolted to the bottom of the base 1. The anti-slip pad 2 is made of rubber.

[0039] Specifically, such as Figure 5 As shown, a sliding block 3 is fixedly connected to the outer side of the limiting plate 504, and the sliding block 3 is slidably connected to the lower mold base 501.

[0040] In this embodiment: by setting an anti-slip pad 2, the anti-slip pad 2 increases the friction between the ground and the base 1 to prevent the support point from being unstable and shaking when cutting the football skin, which would affect the subsequent cutting accuracy and stability. By setting a sliding block 3, when the hydraulic cylinder 503 drives the limiting plate 504 to move, the sliding block 3 then moves synchronously along the groove of the lower mold base 501. Through the guiding effect of the sliding block 3, the limiting plate 504 is smoothly brought close to the football skin, so as to achieve precise positioning and fixation of the football skin.

[0041] Working Principle: In the process of using the precision cutting mold for soccer ball skin, the soccer ball skin is first placed on the lower mold base 501. Then, the hydraulic cylinder 503 is adjusted to drive the limiting plate 504 to move according to the size and shape of the soccer ball skin. The limiting spring 505 at the bottom of the limiting plate 504 and the rubber buffer pad 507 on the fixing plate 506 provide cushioning to avoid damage to the soccer ball skin while ensuring a tight fit and stable positioning. The sliding block 3 on the outer side of the limiting plate 504 is slidably connected to the lower mold base 501, ensuring the smoothness and accuracy of the movement of the limiting plate 504, thus precisely fixing the position of the soccer ball skin in the horizontal direction. Next, the hydraulic cylinder 8 is activated, and its output pushes the upper mold base 10 downwards. The guide rod 11 at the top of the upper mold base 10 is bolted to the lower mold base 501, ensuring that the upper mold base 10 moves along a precise trajectory during its descent. It works in conjunction with the lower mold base 501 to complete the cutting action of the soccer ball skin. Simultaneously, the pressure sensor 9 monitors the pressure of the hydraulic cylinder 8 in real time, ensuring that the cutting pressure is within a suitable range to accommodate soccer ball skins of different materials and thicknesses, ensuring cutting quality and normal mold operation. After completing one soccer ball skin cutting operation, a large amount of debris and waste will remain inside and on the surface of the mold. Then, the control system first starts the second hydraulic cylinder 407. After receiving the start signal, the internal hydraulic system of the second hydraulic cylinder 407 drives the piston to move, causing the output end to extend, so that the top plate 408 extends along with the second hydraulic cylinder 407. The top plate 408 moves smoothly until it precisely reaches the designated position on the top of the lower mold base 501. Then, the cylinder 409 is activated. The air pressure inside the cylinder 409 pushes the piston, causing a linear displacement at the output end of the cylinder 409. This drives the electric rotary brush machine 410 downwards along a preset path until it smoothly enters the lower mold base 501. The motor built into the electric rotary brush machine 410 then rotates at high speed, driving the brush head to rotate at a high speed. During rotation, the bristles fully contact the inner surface and gaps of the lower mold base 501. The strong centrifugal force and friction generated by the high-speed rotation of the bristles effectively remove various debris and waste adhering to the mold surface, causing them to detach from the mold surface. Once the electric rotary brush machine 410 has completed its operation on the lower mold base 501... After the internal cleaning is completed, the output end is retracted by the second hydraulic cylinder 407. Under the reverse action of the hydraulic system, the top plate 408 drives the electric rotary brush machine 410 back to its initial position along the original path to facilitate subsequent dust collection. Then, the first hydraulic cylinder 402 is activated, and its output end extends, pushing the suction plate 403 forward. The fine plate then generates negative pressure on the area on the top of the lower mold base 501 that has been cleaned by the electric rotary brush machine 410, thus adsorbing and cleaning it. Under the action of negative pressure, the waste material loosened by the electric rotary brush machine 410 on the lower mold base 501 is sucked into the connecting hose 404 through the suction holes of the suction plate 403. The waste material is transported within the connecting hose 404 by airflow.The dust is collected smoothly into the dust collection bin inside the vacuum cleaner 405, achieving efficient cleaning of the soccer ball skin cutting mold. This ensures the mold remains in good working condition during subsequent operations, thereby improving the precision and quality of soccer ball skin cutting.
