Description

Technical Field

[0001] This utility model relates to the field of ultrasonic processing technology, and in particular to an ultrasonic cutter mechanism for cutting gates. Background Technology

[0002] Currently, in the injection molding industry, gate treatment of plastic products typically relies on manual or mechanical cutting. Because the gate is tightly connected to the product body, high precision is required during cutting to avoid damaging the product surface. Traditional cutting tools such as blades or scissors are difficult to operate consistently, especially in mass production where they are inefficient and labor-intensive. Furthermore, when using ordinary mechanical cutters, the equipment has poor adaptability to products of different shapes and sizes, requires complex parameter adjustments, and is prone to deformation or damage due to excessive cutting force. In addition, waste and heat generated during cutting, if not handled promptly, can affect product quality and the production environment. Although ultrasonic cutting technology has been gradually introduced, existing equipment is mostly focused on single-function implementation, and there is still room for improvement in stability and efficiency.

[0016] This utility model provides an ultrasonic cutter mechanism for cutting gates, the overall structure of which is as follows: Figure 1As shown. The base 1 is the main supporting component of the entire mechanism. The ultrasonic generating module 2, vibration transmission assembly 3, cutter assembly 4, and positioning fixture 5 are all mechanically fixed to the base 1. The ultrasonic generating module 2 includes a high-frequency oscillator and a transducer connected to it. The high-frequency oscillator is fixed to one side of the base 1 by bolts, and the transducer is connected to the high-frequency oscillator through a flange and connected to the vibration transmission assembly 3 through a threaded interface. The vibration transmission assembly 3 is a metal rod with a spiral cooling groove 6 on its surface. The cooling groove 6 contains a heat conduction pipe 7, which dissipates heat through an external cooling circulation system. A temperature sensor is also installed in the cooling groove 6, which is connected to an external control panel via wires to monitor the operating temperature of the vibration transmission assembly 3 in real time.

[0017] The vibration transmission assembly 3 has a tapered connector 8 at its end, which is threaded to the cutter assembly 4. The cutter assembly 4 includes a blade 9, a blade holder 10, and an adjusting nut 11. The blade 9 is fixed to the blade holder 10 by a pressure plate, and the blade holder 10 is connected to the tapered connector 8 via the adjusting nut 11. The adjusting nut 11 can adjust the angle and position of the blade 9 to accommodate the cutting needs of gates of different shapes and sizes. The blade 9 is made of high-hardness ceramic material, with a micro-serrated structure on the cutting edge. The spacing of the micro-serrations is 0.2mm to 0.5mm, the thickness is 1mm to 3mm, the width is 5mm to 20mm, and the length is 50mm to 100mm. The tail of the blade 9 has a locating pin hole, which engages with a locating pin on the blade holder 10 to ensure the accuracy and stability of the blade installation. The specific connection method between the cutter assembly 4 and the vibration transmission assembly 3 is as follows: Figure 2 As shown, the design of the tapered connector 8 ensures a tight connection between the cutter assembly 4 and the vibration transmission assembly 3, while facilitating the disassembly and replacement of the blade 9.

[0018] The positioning fixture 5 includes a base plate 12, a slide rail 13 mounted on the base plate 12, and a movable clamping block 14 mounted on the slide rail 13. The base plate 12 is fixed to the base 1 with bolts, and the slide rail 13 is arranged along the length of the base plate 12. The movable clamping block 14 is connected to the slide rail 13 via a ball screw. One end of the ball screw is equipped with a handwheel. By rotating the handwheel, the movable clamping block 14 can be moved horizontally along the slide rail 13, thereby adjusting the distance between the movable clamping block 14 and the fixed clamping block 15 to accommodate injection molded products of different sizes. The fixed clamping block 15 is fixed to one end of the base plate 12 with screws. Both the fixed clamping block 15 and the movable clamping block 14 have rubber pads on their clamping surfaces, and the surface of the rubber pads has anti-slip textures. The specific structure of the positioning fixture 5 is as follows: Figure 2 As shown, the arrangement of the slide rail 13 and the ball screw ensures that the movement of the clamping block is smooth and precise, meeting the clamping requirements of products of different sizes.

[0019] The base 1 has a waste collection trough 16 at its bottom, located directly below the cutter assembly 4 and connected to the base 1 via a snap-fit. The bottom of the waste collection trough 16 has an inclined guide plate, the lowest point of which is connected to a waste discharge pipe, which is connected to an external waste recycling device. The side walls of the waste collection trough 16 have ventilation holes, each containing a filter screen to filter dust and debris generated during the cutting process. The top of the base 1 has a protective cover 17, connected to the base 1 via a hinge. The inner side of the protective cover 17 has a sound-absorbing cotton layer that absorbs noise generated during ultrasonic cutting. The front of the protective cover 17 has a transparent observation window made of high-temperature resistant tempered glass, allowing operators to observe the cutting process in real time.

[0020] The operating principle of this utility model is as follows: The operator first places the injection-molded product to be cut on the positioning fixture 5, and adjusts the position of the movable clamping block 14 by rotating the handwheel so that it clamps the product together with the fixed clamping block 15. Then, the ultrasonic generating module 2 is activated, and the high-frequency oscillator generates a high-frequency electrical signal, which is transmitted to the transducer. The transducer converts the electrical signal into mechanical vibration and transmits it to the cutting assembly 4 through the vibration transmission component 3. The blade 9 in the cutting assembly 4 cuts the gate of the injection-molded product under the action of high-frequency vibration. A heat-conducting pipe 7 is embedded in the cooling tank 6 on the surface of the vibration transmission component 3. The heat-conducting pipe 7 quickly dissipates the heat generated during vibration through an external cooling circulation system, ensuring stable operation of the equipment for a long time. A temperature sensor in the cooling tank 6 monitors the operating temperature in real time. When the temperature exceeds the set value, the control panel automatically starts the cooling circulation system to maintain a safe operating temperature.

[0021] Waste generated during the cutting process falls into the waste collection tank 16. The waste is then collected by a guide plate and directed to the waste discharge pipe, ultimately entering an external waste recycling device. Ventilation holes on the sidewalls of the waste collection tank 16 effectively filter dust and debris, preventing environmental pollution. The protective cover 17 not only protects operators from flying debris during cutting, but its inner sound-absorbing layer significantly reduces noise generated during the cutting process, improving working comfort. A transparent observation window allows operators to monitor the cutting status at any time and adjust process parameters promptly.

[0022] In practical applications, this invention allows for adjustment of the angle and position of the blade 9 in the cutting assembly 4 according to different production needs, adapting to gate cutting tasks of different shapes and sizes. For example, when processing small-sized gates, the angle of the blade 9 can be made more perpendicular by adjusting the nut 11, thereby improving cutting accuracy. For large-sized gates, the angle of the blade 9 can be appropriately adjusted to increase the cutting range. Furthermore, the flexible design of the positioning clamp 5 allows the mechanism to be applicable to various specifications of injection molded products, significantly improving the adaptability of the equipment. Through the above structural design and operating principle, this invention achieves efficient and precise gate cutting, solving the problems of low efficiency, poor accuracy, and untimely waste and heat treatment in traditional technologies.

[0023] To enable those skilled in the art to fully understand and implement this utility model, the specific implementation principle of this utility model is further explained below in conjunction with a specific application scenario.

[0024] On the injection molding production line, the operator first places the injection molded product to be cut onto the positioning fixture 5. The position of the movable clamping block 14 is adjusted by rotating the handwheel, so that it, together with the fixed clamping block 15, clamps the product. At this time, the arrangement of the slide rail 13 and the ball screw ensures the smooth movement of the movable clamping block 14, while the anti-slip texture on the surface of the rubber pad enhances the clamping stability and avoids damage to the product surface, thus achieving precise positioning of products of different sizes.

[0025] Subsequently, the ultrasonic generator module 2 is activated, and the high-frequency oscillator generates a high-frequency electrical signal, which is transmitted to the transducer. The transducer converts the electrical signal into mechanical vibration and transmits it to the cutter assembly 4 through the vibration transmission component 3. The cooling tank 6 of the vibration transmission component 3 is embedded with a heat-conducting pipe 7. The heat-conducting pipe 7 rapidly dissipates the heat generated during vibration through an external cooling circulation system, ensuring stable operation of the equipment over a long period. A temperature sensor within the cooling tank 6 monitors the operating temperature in real time. When the temperature exceeds the set value, the control panel automatically activates the cooling circulation system to maintain a safe operating temperature. This design not only effectively solves the problem of performance degradation due to heat accumulation in traditional technologies but also significantly extends the service life of the equipment.

[0026] The blade 9 in the cutting assembly 4 cuts the gate of the injection molded product under high-frequency vibration. The blade 9 is made of high-hardness ceramic material, with a micro-serrated edge. The serrations are spaced 0.2mm to 0.5mm apart, 1mm to 3mm thick, 5mm to 20mm wide, and 50mm to 100mm long. The micro-serrated design enhances cutting sharpness and reduces cutting resistance, thereby improving cutting efficiency. Furthermore, the adjusting nut 11 can adjust the angle and position of the blade 9 to accommodate gates of different shapes and sizes. For example, when processing small gates, the angle of the blade 9 can be made more perpendicular by adjusting the nut 11, thus improving cutting accuracy; for large gates, the angle of the blade 9 can be adjusted appropriately to increase the cutting range.

[0027] Waste generated during the cutting process falls into the waste collection tank 16. The waste is then collected by a guide plate and directed to the waste discharge pipe, ultimately entering an external waste recycling device. Filter screens are installed in the ventilation holes on the side walls of the waste collection tank 16 to filter dust and debris generated during the cutting process, preventing environmental pollution. The protective cover 17 not only protects operators from flying debris during cutting, but its inner sound-absorbing cotton layer also significantly reduces noise generated during cutting, improving the comfort of the working environment. A transparent observation window allows operators to monitor the cutting status at any time to adjust process parameters promptly.

[0028] In practical applications, this invention allows for adjustment of the blade 9 angle and position of the cutting assembly 4 according to different production needs. For example, for injection molded products with complex shapes, the angle of the blade 9 can be finely adjusted by adjusting the nut 11 to match the geometric features of the gate, thereby achieving efficient and precise cutting. Furthermore, the flexible design of the positioning clamp 5 allows the mechanism to be applied to injection molded products of various specifications, significantly improving the adaptability of the equipment.

[0029] By combining the above steps and principles, this invention achieves efficient and precise gate cutting, solving the problems of low efficiency, poor precision, and untimely waste and heat treatment in traditional technologies. Meanwhile, the design of the waste collection tank 16 and the protective cover 17 effectively improves the production environment, reduces operational risks, and meets the needs of mass production.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
