Description

Technical Field

[0001] This utility model relates to the field of injection molding technology, and more specifically, to a nut injection molding feeding device. Background Technology

[0002] Injection molding is a highly efficient and precise plastic processing technology. It involves injecting molten plastic into a mold, which then cools and solidifies to form the desired product. This process offers advantages such as high production efficiency, high product precision, and low cost, and is widely used in fields such as electronics, automobile manufacturing, and medical devices.

[0003] In some injection molding processes, cylindrical nuts need to be installed onto a positioning structure inside the injection mold before injection molding. Current production methods rely on manual nut placement. Operators manually pick up the nuts, place them on a nut fixture, and then push the nut into the mold to complete the injection molding process. This manual nut placement method results in low precision, hindering the improvement of the quality of the molded parts, leading to high rework rates and production costs. Furthermore, manual operation is prone to mold damage due to pressure, causing economic losses. For mass production, even more manpower is required, but the efficiency of manual operation remains unchanged, resulting in low production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a nut injection molding feeding device with a simple structure and high production efficiency.

[0005] The technical solution adopted by the nut injection molding feeding device disclosed in this utility model is:

[0006] A nut injection molding feeding device includes a frame, a nut feeding mechanism mounted on the frame, and a nut conveying mechanism for feeding nuts into a mold for injection molding. The nut feeding mechanism includes an inclined slide rail and a nut positioning fixture. The nut positioning fixture has a nut positioning hole that communicates with the slide rail. The nut conveying mechanism includes an implanted robotic arm and a nut adsorption assembly. The nut adsorption assembly includes a pneumatic component and a nut adsorption mandrel. The nut adsorption mandrel has a receiving cavity. The nut adsorption mandrel can adsorb the nut on the nut positioning hole through the pneumatic component, or install the nut in the receiving cavity into the injection mold.

[0007] As a preferred embodiment, the slide rail is provided with limiting plates on both sides, and a limiting channel is formed between the limiting plates. The width of the limiting channel is slightly larger than the width of the nut. The limiting plates are provided with limiting baffles, and one end of the limiting baffles is chamfered.

[0008] As a preferred embodiment, the upper end of the slide rail is provided with a sliding roller, and the two ends of the sliding roller are fixed to the limiting plate. The chamfer of the sliding roller and the limiting baffle forms a nut feeding port.

[0009] As a preferred embodiment, the nut positioning fixture includes a base and a fixing plate, the nut positioning hole is provided on one side of the fixing plate, the base is provided with a limiting groove that communicates with the limiting channel, and the nut positioning hole communicates with the limiting groove.

[0010] As a preferred embodiment, the limiting groove is inclinedly disposed on the base, and the slope of the limiting groove is consistent with the slope of the slide rail.

[0011] As a preferred embodiment, the nut conveying mechanism further includes a movable frame, the nut adsorption assembly is fixed on the movable frame, the upper end of the movable frame is connected to a rotating component, the rotating component is connected to the implantation robot, and the nut adsorption assembly can rotate via the rotating component.

[0014] As a preferred embodiment, a sprue discharge chute is provided on one side of the frame.

[0015] The beneficial effects of the nut injection molding feeding device disclosed in this utility model are as follows: The nut enters the inclined slide rail from the external feeding system. Under the action of gravity, the nut slides automatically along the slide rail. When the nut slides to the end of the slide rail, it enters the nut positioning hole of the nut positioning fixture. The shape and size of the nut positioning hole match the nut, ensuring that the nut is stably placed and accurately positioned. A robotic arm is inserted to move the nut adsorption component to the side of the nut positioning fixture and align the receiving cavity of the nut adsorption mandrel with the nut positioning hole. The pneumatic component generates negative pressure to lift the nut from the nut positioning hole. The nut is adsorbed into the receiving cavity through the hole. Driven by the implantation robot, the nut adsorption mandrel moves along a preset path. When the implantation robot accurately places the nut adsorption mandrel at the designated position in the injection mold, the pneumatic component switches the air path from negative pressure to positive pressure, causing the nut to detach from the receiving cavity of the adsorption mandrel and be accurately installed in the injection mold. After the nut is implanted, the implantation robot drives the nut adsorption assembly back to the initial position, ready for the next adsorption and implantation operation. The whole process is continuous and highly automated, which can effectively improve production efficiency and product quality. Attached Figure Description

[0020] A nut injection molding feeding device includes a frame, a nut feeding mechanism mounted on the frame, and a nut conveying mechanism for feeding nuts into a mold for injection molding. The nut feeding mechanism includes an inclined slide rail and a nut positioning fixture. The nut positioning fixture has a nut positioning hole that communicates with the slide rail. The nut conveying mechanism includes an implanted robotic arm and a nut adsorption assembly. The nut adsorption assembly includes a pneumatic component and a nut adsorption mandrel. The nut adsorption mandrel has a receiving cavity. The nut adsorption mandrel can adsorb the nut on the nut positioning hole through the pneumatic component, or install the nut in the receiving cavity into the injection mold.

[0021] The nut enters the inclined slide rail from the external feeding system. Under the action of gravity, the nut slides automatically along the slide rail. When the nut reaches the end of the slide rail, it enters the nut positioning hole of the nut positioning fixture. The shape and size of the nut positioning hole match the nut, ensuring that the nut is stably placed and accurately positioned. The implantation robot moves the nut adsorption assembly to the side of the nut positioning fixture and aligns the receiving cavity of the nut adsorption mandrel with the nut positioning hole. The pneumatic component generates negative pressure to adsorb the nut from the nut positioning hole into the receiving cavity. The nut adsorption mandrel with the nut adsorbed moves along a preset path under the action of the implantation robot. When the implantation robot accurately reaches the designated position of the nut adsorption mandrel in the injection mold, the pneumatic component switches the air path from negative pressure to positive pressure, causing the nut to detach from the receiving cavity of the adsorption mandrel and accurately install into the injection mold. After the nut is implanted, the implantation robot moves the nut adsorption assembly back to the initial position, ready for the next adsorption and implantation operation. The whole process is continuous and cyclical, with a high degree of automation, which can effectively improve production efficiency and product quality.

[0022] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings:

[0023] Please refer to Figures 1 to 4A nut injection molding feeding device includes a frame 10, a nut feeding mechanism 20, a nut conveying mechanism 30, and a sprue discharge slide 40. Multiple mounting profiles are fixedly mounted on the upper surface of the frame 10. The nut feeding mechanism 20 is fixed to the profiles and is used to position and supply nuts. The nut conveying mechanism 30 is located on one side of the nut feeding mechanism 20 and feeds the nuts from the nut feeding mechanism 20 into the mold for injection molding. The sprue discharge slide 40 is used to handle the sprue material generated during the injection molding process.

[0024] The nut feeding mechanism 20 includes a slide rail 21 and a nut positioning fixture 22. The slide rail 21 is inclined, allowing nuts placed within it to slide down by their own weight without requiring an additional power device, thus saving equipment costs. In this embodiment, nuts can be manually placed onto the slide rail 21, and replenished periodically when all nuts are absorbed. In another embodiment, a vibratory feeder can be connected to one end of the slide rail 21 as a nut feeding system. One end of the vibratory feeder is connected to a conveying pipe, which is connected to the upper end of the slide rail 21. The vibratory feeder vibrates and discharges the nuts, which then flow neatly onto the slide rail 21 in a specific direction through the conveying pipe. Because the vibratory feeder can automatically arrange and transport disordered parts to designated positions, it greatly reduces manual operation time and labor intensity, making it suitable for large-scale production.

[0025] The slide rail 21 is provided with limiting plates 211 on both sides, and a limiting channel 212 is formed between the limiting plates 211. The width of the limiting channel 212 is slightly larger than the width of the nut, which can effectively limit the position of the nut in the slide rail 21, prevent the nut from shifting or getting stuck during sliding, and ensure that the nut slides down smoothly. The limiting plates 211 can prevent the nut from falling off the slide rail 21 and onto the frame 10, avoiding economic losses. The limiting plates 211 are provided with limiting baffles 213. The height between the limiting baffles 213 and the limiting channel 212 is slightly higher than the height of the nut, so that the slide rail 21 is only suitable for injection molding of nuts of the same size, preventing nuts of different specifications from being mixed in and causing injection failure. Moreover, the slide rail 21 with different widths of the limiting channel 212 can be replaced according to the size of the nut required for the actual injection molded part, making the nut injection molding feeding device more applicable.

[0026] The upper end of the slide rail 21 is provided with a sliding roller 214. The two ends of the sliding roller 214 are fixed on the limiting plate 211. The sliding roller 214 can prevent the nut from falling off at the upper end of the slide rail 21. One end of the limiting baffle 213 is provided with a chamfer. The sliding roller 214 and the chamfer of the limiting baffle 213 form a nut feeding port 215. The nut feeding port 215 can be connected to the conveying pipe of the vibratory feeder. The chamfer design can reduce the resistance of the nut sliding into the slide rail 21 and improve the smoothness of feeding.

[0027] In this embodiment, the limiting plate 211 is equipped with an alarm. The alarm is used to detect whether the number of nuts in the slide rail 21 can continue to operate normally. When the number of nuts is less than a certain amount, the alarm will sound to remind the staff to add nuts to the nut feeding mechanism 20.

[0028] The nut positioning fixture 22 includes a base 221 and a fixing plate 222. The nut positioning hole 223 is provided on one side of the fixing plate 222. The base 221 is provided with a limiting groove 2211 that communicates with the limiting channel 212, ensuring that the nut can smoothly enter the nut positioning hole 223 after sliding from the slide rail 21. The diameter of the nut positioning hole 223 is slightly larger than the diameter of the nut end face, which can further improve the positioning accuracy of the nut and make the position of the nut adsorbed by the nut conveying mechanism 30 more accurate.

[0029] The nut positioning hole 223 is connected to the limiting groove 2211. The limiting groove 2211 is inclined on the base 221, and the slope of the limiting groove 2211 is consistent with the slope of the slide rail 21. This makes the transition of the nut between the slide rail 21 and the nut positioning fixture 22 smoother, reduces the obstruction of the nut sliding from the slide rail 21 into the limiting groove 2211, and improves the efficiency of nut feeding.

[0030] In this embodiment, a sensing mechanism is provided near the limiting groove 221 to detect whether there is a nut in the nut positioning hole 223 and to feed the result back to the nut conveying mechanism 30 to ensure that the next action or the sensing nut is accurately grasped.

[0031] The nut conveying mechanism 30 includes an implanted robotic arm 31 and a nut adsorption assembly 32. The nut adsorption assembly 32 includes a pneumatic component 321 and a nut adsorption core 322. The nut adsorption core 322 is provided with a receiving cavity 3221. The nut adsorption core 322 can adsorb the nut on the nut positioning hole 223 through the pneumatic component 321, or install the nut in the receiving cavity 3221 into the injection mold.

[0032] The working principle of this utility model is as follows: The nut enters the inclined slide rail 21 from the external feeding system. Under the action of gravity, the nut slides automatically along the slide rail 21. When the nut slides to the end of the slide rail 21, it slides into the nut positioning hole 223 of the nut positioning fixture 22. The shape and size of the nut positioning hole 223 match the nut, ensuring that the nut is stably placed and accurately positioned. The implanted robot arm 31 drives the nut adsorption assembly 32 to move to the side of the nut positioning fixture 22, aligning the receiving cavity 3221 of the nut adsorption core 322 with the nut positioning hole 223. The pneumatic component 3... 21. By generating negative pressure, the nut is adsorbed from the nut positioning hole 223 into the receiving cavity 3221. The nut adsorption mandrel 322 with the nut adsorbed is moved along a preset path by the implantation robot 31. When the implantation robot 31 accurately reaches the designated position of the injection mold, the pneumatic component 321 switches the air path from negative pressure to positive pressure, so that the nut is detached from the receiving cavity 3221 of the adsorption mandrel and accurately installed in the injection mold. After the nut is implanted, the implantation robot 31 drives the nut adsorption assembly 32 back to the initial position, ready for the next operation.

[0033] The nut conveying mechanism 30 also includes a movable frame 33, on which the nut adsorption assembly 32 is fixed. The upper end of the movable frame 33 is connected to a rotating component 331, which is connected to the implantation robot 31. The nut adsorption assembly 32 can rotate via the rotating component 331. This design increases the flexibility of the nut adsorption assembly 32, enabling it to adapt to the needs of nut gripping and implantation in different directions, and improving the versatility and adaptability of the equipment.

[0034] The movable frame 33 is provided with a positioning post 332 on one side. The nut adsorption assembly 32 can be positioned and injected with the injection mold through the positioning post 332, ensuring that the nut adsorption assembly 32 can accurately insert the nut into the injection mold, reducing injection defects caused by position deviation and improving product quality.

[0035] The other side of the movable frame 33 is provided with a clamping drive 333. The output end of the clamping drive 333 is connected to a clamping fixture 334. After the nut is injection molded, the clamping drive 333 drives the clamping fixture 334 to clamp the finished product. Through cooperation with the rotating part 331, the finished product after injection molding is placed on the production line for collection, reducing manual intervention and lowering labor costs.

[0036] The clamping fixture 334 can be adjusted to accommodate different injection-molded products, making it suitable for various shapes and medium to large sizes. This allows the equipment to better meet diverse production needs, improving its versatility and applicability.

[0037] In another embodiment, the clamping fixture 334 can be replaced by installing an air nozzle or air plate on the movable frame 33. The design of the air nozzle or air plate is relatively simple, without the need for complex mechanical structures and drive devices, which can reduce the manufacturing cost and maintenance difficulty of the equipment, while reducing the size and weight of the equipment. It is suitable for lightweight or small injection molded products, and can quickly and efficiently complete the collection of finished products, effectively improving the automation level and production efficiency of the nut injection molding feeding device.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
