[0011] According to the injection mold for a children's bicycle frame of this utility model, one end of the lead screw is rotatably connected to the mounting frame, one end of the atomizing nozzle is rotatably connected to the moving frame, the outer surface of the atomizing nozzle is rotatably connected to the outer shell, the mold release agent storage device is installed on the outer surface of the outer shell by a fixing hoop, and the nozzle is rotatably connected, so that the angle of the nozzle can be flexibly adjusted to ensure that the mold release agent spray covers the main area of ​​the mold.

[0012] Beneficial effects:

[0013] In this technical solution, the injection mold for a children's bicycle frame uses a release agent storage device that delivers the release agent to an atomizing nozzle via pipes and a pump. The atomizing nozzle then sprays the release agent onto the upper and lower molds. Since the atomizing nozzle is located inside the outer casing, it minimizes the leakage of the atomized release agent, preventing environmental pollution. A pneumatic telescopic rod allows the atomizing nozzle and outer casing to move between the upper and lower molds. A motor then rotates a lead screw, enabling further movement of the nozzle and casing between the molds. Finally, a motor rotates gear one, allowing the atomizing nozzle to adjust its angle within the outer casing, ensuring the release agent is sprayed onto the designated area. This process reduces manual operation and minimizes human error risks. Attached Figure Description

A mounting bracket 4 is fixedly connected to the output end of the pneumatic telescopic rod 3. A motor 5 is fixedly connected to the outer surface of the mounting bracket 4. A lead screw 6 is fixedly connected to the output end of the motor 5, converting rotary motion into linear motion. It mainly consists of a threaded rod and a nut, etc., and is powered by electricity. Machine 5 rotates a lead screw 6, whose thread engages with a nut. As the lead screw 6 rotates, the nut moves up or down or slides along the thread. A movable frame 7 is threaded onto the outer surface of the lead screw 6. A motor 8 is fixedly connected to the outer surface of the movable frame 7. A gear 9 is fixedly connected to the output end of the motor 8. A gear 10 is meshed onto the outer surface of the gear 9. An atomizing nozzle 11 is fixedly connected to the inner wall of the gear 10, which transforms the liquid into fine, uniform droplets to increase the contact area between the liquid and the object. It mainly consists of a nozzle head, a liquid supply pipeline, and a pressure regulating device. The liquid is ejected at high pressure or through a specially designed nozzle at high speed, subjected to shear... Shear force generates fine liquid mist. The outer surface of the atomizing nozzle 11 is fixedly connected to a release agent storage device 19 via pipes and pumps. This device safely and stably stores a large amount of release agent, ensuring a continuous supply during production. It mainly consists of a storage tank and a delivery pump. The release agent is stored in a sealed storage tank and impurities are filtered through a material pipe and filter. According to the spraying requirements, the delivery pump is started. The pump generates pressure through mechanical or diaphragm means to extract the release agent from the storage tank. The outer surface of the moving frame 7 is fixedly connected to a shell 12. The atomizing nozzle 11 is located inside the shell 12, which is located between the upper mold 101 and the lower mold 102.

[0023] A protective shell 13 is fixedly connected to the outer surface of the movable frame 7. Gear 1 9 and gear 2 10 are located inside the protective shell 13. A baffle 14 is fixedly connected to the outer surface of the mounting frame 4. A through groove 15 is provided on the outer surface of the baffle 14. The movable frame 7 is located inside the through groove 15. The outer surface of the movable frame 7 is in contact with the inner wall of the mounting frame 4. Both the outer surface of the movable frame 7 and the inner wall of the mounting frame 4 are smooth surfaces. A guide rod 16 is fixedly connected to the inner side of the fixed frame 2. The outer surface of the guide rod 16 is slidably connected to the mounting frame 4. A limiting piece 17 is fixedly connected to one end of the guide rod 16. The outer surface of the limiting piece 17 abuts against the mounting frame 4. An identification box 18 is fixedly connected to the outer surface of the fixed frame 2. An identification plate is placed inside the identification box 18. One end of the lead screw 6 is rotatably connected to the mounting frame 4. One end of the atomizing nozzle 11 is rotatably connected to the movable frame 7. The outer surface of the atomizing nozzle 11 is rotatably connected to the outer shell 12. The release agent storage device 19 is installed on the outer surface of the outer shell 12 by a fixing hoop.

[0024] Specifically, the release agent storage device 19 delivers the release agent to the atomizing nozzle 11 via pipes and a pump. The atomizing nozzle 11 then sprays the release agent onto the upper mold 101 and the lower mold 102. Since the atomizing nozzle 11 is located inside the housing 12, it reduces the outward dispersion of the atomized release agent, preventing environmental pollution. The extension and retraction of the pneumatic telescopic rod 3 allows the mounting frame 4 to move. This movement of the mounting frame 4 moves the atomizing nozzle 11 and the housing 12 between the upper mold 101 and the lower mold 102. Then, the motor 5 rotates the lead screw 6, causing the movable frame 7, threadedly connected to the lead screw 6, to move the atomizing nozzle 11 and the housing 12 between the upper mold 101 and the lower mold 102. Finally, the motor 8 rotates the gear 9, causing the gear 10 meshing with the gear 9 to adjust the angle of the atomizing nozzle 11. This allows the atomizing nozzle 11 to adjust its angle within the housing 12, ensuring the release agent is sprayed onto the designated area while reducing manual operation and minimizing human error risks.

[0025] Working principle: During use, the pneumatic telescopic rod 3 extends and retracts, allowing the mounting frame 4 to move. The movement of the mounting frame 4 moves the atomizing nozzle 11 and the outer casing 12 between the upper mold 101 and the lower mold 102. Then, the motor 5 rotates the lead screw 6, which causes the moving frame 7, threadedly connected to the lead screw 6, to move the atomizing nozzle 11 and the outer casing 12 between the upper mold 101 and the lower mold 102. Then, the motor 8 rotates the gear 9, which meshes with the gear 10, causing the atomizing nozzle 11 to adjust its angle. This allows the atomizing nozzle 11 to adjust its angle within the outer casing 12, ensuring that the release agent is sprayed onto the designated area. This reduces manual operation and the risk of human error. Furthermore, the atomizing nozzle 11 being inside the outer casing 12 reduces the spillage of the atomized release agent, preventing environmental pollution.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
