Description

Technical Field

[0001] This utility model relates to the field of silicone product trimming technology, specifically a multi-station synchronous trimming and shaping mold for silicone buttons. Background Technology

[0002] Silicone buttons are elastic button components made primarily of silicone. Due to their excellent flexibility, weather resistance, and long service life, they are widely used in various control panels inside automobiles, including center console buttons, window controls, steering wheel function buttons, and many other components. Silicone buttons used in the vehicle environment must meet stringent performance requirements, including high-temperature resistance, weather resistance, electrical insulation, and physiological inertness. These characteristics make silicone buttons an indispensable functional component in automotive manufacturing. The manufacturing process of silicone buttons typically involves multiple steps, including silicone refining, cutting, molding, and trimming. The trimming process is particularly critical because molded silicone buttons often have burrs and flash, requiring meticulous trimming to meet dimensional requirements and appearance quality. Traditional trimming largely relies on manual operation, resulting in low production efficiency and difficulty in ensuring consistent quality.

[0003] An existing patent (publication number: CN219132951U) discloses a trimming device for silicone ring production. The trimming device for silicone ring production includes a conveyor belt and a fixed box. A PLC controller is provided on the front surface of the fixed box, and a dust collection component is provided on one side of the fixed box. The dust collection component includes a gathering box, an exhaust fan, and a suction pipe. The gathering box is fixedly connected to one side of the fixed box, and the exhaust fan is fixedly connected to one side of the fixed box. The air outlet of the exhaust fan is connected to the front surface of the gathering box, and the air inlet of the exhaust fan is connected to the suction pipe.

[0004] However, the above-mentioned device cannot efficiently trim multiple silicone rings when trimming the edges, resulting in low trimming efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a multi-station synchronous trimming and shaping mold for silicone buttons, which has the advantage of simultaneously trimming multiple silicone buttons and solves the problem of low trimming efficiency when trimming the edges of silicone rings, as it cannot efficiently trim multiple silicone rings.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-station synchronous trimming and shaping mold for silicone buttons, including a base and an adjustment component disposed inside the base. The base surface is also equipped with a trimming component, which is disposed on one side of the adjustment component. The adjustment component includes a mounting frame and a fixing unit and a material handling unit disposed on the mounting frame.

[0007] The fixing unit includes a rotating rod passing through the base. A first support plate is fixed to the upper end of the rotating rod. A rotating plate corresponding to the first support plate is provided on the lower surface of the mounting frame. A telescopic rod is fixed to the lower surface of the rotating plate. A pressure plate is fixed to the lower end of the telescopic rod. The pressure plate is positioned corresponding to the first support plate. A second support plate is fixed to the upper surface of the rotating plate through a connecting rod. The rotating plate, telescopic rod, and pressure plate rotate synchronously with the second support plate through the connecting rod.

[0008] Furthermore, a transmission chamber is provided inside the base, and the lower end of the rotating rod is rotatably connected to the bottom wall of the transmission chamber. A first motor is fixed to the inner wall of the transmission chamber, and a worm gear is fixed to the output end of the first motor. A worm wheel is fixed to the surface of the rotating rod, and the worm wheel and the worm gear cooperate with each other. The rotating rod and the first support plate rotate on the surface of the mounting frame through the first motor, the worm gear and the worm wheel. A spring is sleeved on the outer periphery of the telescopic rod.

[0009] The above scheme, employing a worm gear transmission mechanism, ensures the smoothness and precision of the transmission, avoiding the vibration and errors that may occur with traditional gear transmission. The spring configuration provides a stable clamping force, which not only integrates multiple sets of telescopic rods, pressure plates, and the second support plate into a whole, enabling synchronous rotation when the rotating rod and the first support plate rotate, thus allowing multiple workstations to operate simultaneously, but also ensures that silicone buttons of different thicknesses can receive uniform fixing force, improving the adaptability and stability of the equipment.

[0010] Furthermore, the material handling unit includes a handwheel disposed above the mounting frame, a threaded rod fixed to the lower surface of the handwheel, a movable chamber opened inside the mounting frame, the lower end of the threaded rod being rotatably connected to the bottom wall of the movable chamber, a threaded cap being threadedly connected to the surface of the threaded rod, a movable rod being fixed to the side of the threaded cap, a first magnet being fixed to the lower surface of the movable rod, and a second magnet corresponding to the first magnet being fixed to the upper surface of the pressure plate, wherein the attraction force of the first magnet and the second magnet is greater than the restoring force of the spring.

[0011] In the above scheme, the handwheel drives the threaded rod to rotate, which in turn drives the threaded cap to move. This causes the moving rod fixed to the side of the threaded cap and the first magnet fixed to the lower end of the moving rod to move synchronously. When the first magnet and the second magnet attract each other, the handwheel is rotated in the opposite direction, allowing the second support plate to move upward with the moving rod via the first and second magnets. This releases the clamping of the silicone button, making it easier to replace the silicone button. After replacement, the moving rod continues to move upward. When the movement of the moving rod exceeds the compression limit of the spring, the first magnet and the second magnet separate, and the second support plate moves in the opposite direction under the reaction force of the spring, thus fixing the replaced silicone button.

[0012] Furthermore, the mounting bracket has a movable groove on its side, which is connected to the movable compartment, and the movable rod passes through the movable groove.

[0013] Through the above scheme, the moving groove ensures the linear motion accuracy of the moving rod, avoids skew and jamming, and ensures the stability of the moving rod and the first magnet during operation.

[0014] Furthermore, the trimming assembly includes a support rod, and the base surface has a movable groove. Both ends of the support rod are fixed to the inner wall of the movable groove. A fixed frame is movably arranged on the surface of the support rod. A second motor is installed on the upper surface of the fixed frame. A cleaning blade is fixed at the output end of the second motor. The cleaning blade is rotatably mounted on the fixed frame, and the tilt angle of the cleaning blade is adjusted by the second motor.

[0015] The above solution, by adjusting the angle of the cleaning blade with a second motor, can adapt to the trimming needs of silicone buttons of different shapes and sizes, improving the versatility and adaptability of the equipment, ensuring the consistency of the trimming angle, and improving the trimming quality and precision.

[0016] Furthermore, an electric actuator is fixed to the inner wall of the movable groove, and the output end of the electric actuator is fixed to the side of the fixed frame. The fixed frame moves inside the movable groove through the support rod and the electric actuator.

[0017] Furthermore, a collection plate is fixed to the upper surface of the base, the surface of the collection plate has an inclined surface and a groove corresponding to the mounting bracket, and a collection box is also inserted inside the base, the collection box being disposed inside the movable groove.

[0018] The above solution allows the inclined surface design to automatically collect waste generated during trimming into the collection box, achieving automatic collection and processing of waste, maintaining a clean working environment, reducing the amount of manual cleaning, and improving overall work efficiency.

[0019] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0020] This multi-station synchronous trimming and shaping mold for silicone buttons achieves synchronous fixing and positioning of multiple silicone buttons through the coordinated design of a rotating rod, a first support plate, a rotating plate, and a telescopic rod. This ensures stability and consistency during the trimming process. At the same time, the worm gear mechanism drives the rotating rod, providing smooth and precise transmission and avoiding vibration and errors. Combined with a spring, it provides stable clamping force to adapt to the processing requirements of buttons of different thicknesses. Furthermore, the material handling component can simultaneously remove the clamps from multiple silicone buttons, facilitating the replacement of silicone buttons. Attached Figure Description

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Please see Figure 1 , Figure 2 and Figure 3The multi-station synchronous trimming and shaping mold for silicone buttons in this embodiment includes a base 1 and an adjustment component 2 disposed inside the base 1. A trimming component 3 is also installed on the surface of the base 1 and is disposed on one side of the adjustment component 2. The adjustment component 2 includes a mounting frame 201 and a fixing unit 202 and a material picking unit 203 disposed on the mounting frame 201. The fixing unit 202 includes a rotating rod 2023 passing through the base 1. A first support plate 2025 is fixed to the upper end of the rotating rod 2023. A rotating plate 2026 corresponding to the first support plate 2025 is disposed on the lower surface of the mounting frame 201. A telescopic rod 2027 is fixed to the lower surface of the rotating plate 2026. A pressure plate 2028 is fixed to the lower end of the telescopic rod 2027. The pressure plate 2028 and the first support plate 2025 are connected. Correspondingly, a second support plate 2029 is fixed to the upper surface of the rotating plate 2026 via a connecting rod. The rotating plate 2026, the telescopic rod 2027, and the pressure plate 2028 rotate synchronously with the second support plate 2029 via the connecting rod. Through the coordinated design of the rotating rod 2023, the first support plate 2025, the rotating plate 2026, and the telescopic rod 2027, the synchronous fixing and positioning of multiple silicone buttons is achieved, ensuring stability and consistency during the trimming process. At the same time, the worm gear 2024 and worm 2022 mechanism drive the rotating rod 2023, providing smooth and precise transmission and avoiding vibration and errors. Combined with the spring, it provides stable clamping force to adapt to the processing requirements of buttons of different thicknesses. Furthermore, the material handling assembly can simultaneously remove the clamping of multiple silicone buttons, facilitating the replacement of silicone buttons.

[0033] The base 1 has a transmission chamber 101 inside. The lower end of the rotating rod 2023 is rotatably connected to the bottom wall of the transmission chamber 101. A first motor 2021 is fixed to the inner wall of the transmission chamber 101. A worm gear 2022 is fixed to the output end of the first motor 2021. A worm wheel 2024 is fixed to the surface of the rotating rod 2023. The worm wheel 2024 and the worm gear 2022 cooperate with each other. The rotating rod 2023 and the first support plate 2025 rotate on the surface of the mounting frame 201 through the first motor 2021, the worm gear 2022 and the worm wheel 2024. A spring is sleeved on the outer periphery of the telescopic rod 2027. The worm gear 2024 and worm 2022 transmission mechanism ensures smooth and accurate transmission, avoiding vibration and errors that may occur with traditional gear transmission. The spring configuration provides stable clamping force, which not only makes the multiple sets of telescopic rods 2027, pressure plate 2028 and second support plate 2029 form a whole, so that they can rotate synchronously when the rotating rod 2023 and the first support plate 2025 rotate, thus enabling multiple workstations to work synchronously, but also ensures that silicone buttons of different thicknesses can receive uniform fixing force, improving the adaptability and stability of the equipment.

[0034] Additionally, the material handling unit 203 includes a handwheel 2031 mounted above the mounting frame 201. A threaded rod 2032 is fixed to the lower surface of the handwheel 2031. A movable chamber 2011 is provided inside the mounting frame 201. The lower end of the threaded rod 2032 is rotatably connected to the bottom wall of the movable chamber 2011. A threaded cap 2033 is threaded onto the surface of the threaded rod 2032. A movable rod 2034 is fixed to the side of the threaded cap 2033. A first magnet 2035 is fixed to the lower surface of the movable rod 2034. A second magnet corresponding to the first magnet 2035 is fixed to the upper surface of the pressure plate 2028. The attraction force of the first magnet 2035 and the second magnet is greater than the spring's restoring force. The handwheel 2031 drives the threaded rod 2032 to rotate, and the threaded rod 2032 drives the threaded cap 2033 to move, thereby driving the movable rod 2034 fixed to the side of the threaded cap 2033 and the first magnet 2035 fixed to the lower end of the movable rod 2034 to move synchronously. When the first magnet 2035... After the second magnet 2035 attracts the second magnet, the handwheel 2031 is rotated in the opposite direction, allowing the second support plate 2029 to move upward with the moving rod 2034 via the first magnet 2035 and the second magnet, thereby releasing the clamping of the silicone button and facilitating its replacement. After replacement, the moving rod 2034 continues to move upward. When the movement of the moving rod 2034 exceeds the compression limit of the spring, the first magnet 2035 separates from the second magnet, and the second support plate 2029 moves in the opposite direction under the reaction force of the spring, thereby fixing the replaced silicone button. The mounting bracket 201 has a moving groove 2012 on its side, which is connected to the movable chamber 2011. The moving rod 2034 passes through the moving groove 2012. The moving groove 2012 ensures the linear motion accuracy of the moving rod 2034, avoids skew and jamming, and ensures the stability of the moving rod 2034 and the first magnet 2035 during operation.

[0035] The trimming assembly 3 includes a support rod 302. A movable groove 102 is formed on the surface of the base 1. Both ends of the support rod 302 are fixed to the inner wall of the movable groove 102. A fixed frame 301 is movably mounted on the surface of the support rod 302. A second motor 304 is mounted on the upper surface of the fixed frame 301. A cleaning blade 305 is fixed to the output end of the second motor 304. The cleaning blade 305 is rotatably mounted on the fixed frame 301. The tilt angle of the cleaning blade 305 is adjusted by the second motor 304. This adjustment of the cleaning blade 305's angle can adapt to the trimming needs of silicone buttons of different shapes and sizes, improving the equipment's versatility and adaptability, ensuring the consistency of the trimming angle, and improving trimming quality and precision. An electric push rod 303 is also fixed to the inner wall of the movable groove 102. The output end of the electric push rod 303 is fixed to the side of the fixed frame 301. The fixed frame 301 moves within the movable groove 102 via the support rod 302 and the electric push rod 303.

[0036] It should be noted that a collection plate 5 is also fixed on the upper surface of the base 1. The surface of the collection plate 5 has an inclined surface and a groove corresponding to the mounting bracket 201. A collection box 4 is also installed inside the base 1. The collection box 4 is set inside the movable groove 102. The inclined surface design allows the waste generated during trimming to be automatically collected into the collection box 4, realizing the automatic collection and processing of waste, maintaining the cleanliness of the working environment, reducing the amount of manual cleaning, and improving the overall work efficiency.

[0037] The working principle of the above embodiments is as follows:

[0038] First, place the device in a suitable position. Then, connect the device to an external power source and control equipment. The control equipment specifically includes known conventional devices such as a controller and computer with control functions. Next, the operator drives the threaded rod 2032 to rotate via handwheel 2031. The threaded rod 2032 moves the threaded cap 2033, thereby causing the moving rod 2034 fixed to the side of the threaded cap 2033 and the first magnet 2035 fixed to the lower surface of the moving rod 2034 to move synchronously. When the first magnet 2035 attracts the second magnet, the handwheel 2031 is rotated in the opposite direction, allowing the second support plate 2029 to move upwards along with the moving rod 2034 via the first magnet 2035 and the second magnet. Then, the operation... Personnel can then place the silicone button on the surfaces of the first support plate 2025 and the second support plate 2029. After placement, the moving rod 2034 continues to move upward. When the movement of the moving rod 2034 exceeds the compression limit of the spring, the first magnet 2035 separates from the second magnet, and the second support plate 2029 moves in the opposite direction under the reaction force of the spring, thereby fixing the silicone button. At this time, the first support plate 2025, the silicone button, the telescopic rod 2027, the pressure plate 2028, and the rotating plate 2026 form a whole through the elastic force of the spring. At the same time, the rotating plate 2026 is connected to the second support rod 302 through the connecting rod, so multiple sets of telescopic rods 2027, pressure plates 2028, and second support rods 302 can rotate synchronously.

[0039] Subsequently, the staff controlled the operation of the first motor 2021 through the control equipment. The first motor 2021 drove the worm gear 2022, which in turn drove the worm wheel 2024 to rotate, thereby driving the rotating rod 2023 to rotate, and in turn driving multiple silicone buttons to rotate synchronously. Then, the staff adjusted the angle of the cleaning blade 305 through the second motor 304, and then controlled the operation of the electric push rod 303 through the control equipment, so that the cleaning blade 305 trimmed the burrs on the silicone buttons. The debris generated during the trimming process fell onto the collection plate 5 below. Since the surface of the collection plate 5 has an inclined surface, the debris can fall into the collection box 4 along the inclined surface.
