Technical Field
[0001] This utility model relates to the field of injection molding technology, and in particular to a polycarbonate resin injection molding machine with efficient heating and uniform temperature distribution. Background Technology
[0002] Polycarbonate resin injection molding is the process of shaping polycarbonate resin using injection molding technology. First, the polycarbonate resin is heated to a molten state, then injected into a pre-designed mold using an injection molding machine. After cooling and solidification, the desired part is formed. Injection molding technology enables high-precision, high-volume production and is suitable for manufacturing parts with complex shapes.
[0003] A polycarbonate resin injection molding machine with efficient heating and uniform temperature distribution is an injection molding device specifically designed for polycarbonate resin. It features a precise temperature control system that enables efficient heating and uniform temperature distribution. This type of injection molding machine is typically equipped with advanced heating elements and temperature control technology to ensure that the polycarbonate resin maintains a stable temperature during melting, avoiding localized overheating or underheating and guaranteeing injection molding quality. Uniform temperature control is particularly important for temperature-sensitive materials like polycarbonate, helping to improve the transparency, strength, and dimensional accuracy of the product, making it especially suitable for the production of products requiring high-quality surfaces and precision structures.

[0031] 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.
[0032] Reference Figure 1 and Figure 3 The present invention provides an embodiment of a polycarbonate resin injection molding machine with efficient heating and uniform temperature distribution, comprising a base 1, a support 2 fixedly connected to the front end of the base 1, the support 2 being made of steel to provide sufficient support for waste crushing, a motor 3 fixedly connected to the front end of the support 2, the motor 3 providing sufficient power for subsequent components, a gear 6 fixedly connected to the drive end of the motor 3, and a roller 5 fixedly connected to the rear end of the gear 6, the roller 5 being supported by steel and having protrusions on its surface to better crush waste;
[0033] Roller 4, made of steel, is rotatably connected inside bracket 2. Roller 4 also has protrusions on its surface, which engage with protrusions on roller 5. Gear 7 is fixedly connected to the front end of roller 4. Collection box 8 is slidably connected inside bracket 2. The precise meshing of gears 6 and 7 makes the waste recycling process smoother and prevents jamming, thus improving waste processing efficiency. When motor 3 operates, it drives gear 6 to rotate, which in turn drives gear 7 to rotate, thereby causing relative movement between roller 5 and roller 4.
[0034] The relative rotation of roller 4 and roller 5 allows the processed waste to be fed into the collection box 8 while it is being crushed. This combination of crushing and conveying greatly improves the automation of waste processing, reduces manual intervention, and increases production efficiency. When a sufficient amount of processed waste accumulates inside the collection box 8, it is transported out using handles at both ends. This design makes waste processing more convenient, allowing workers to easily handle the waste.
[0035] Reference Figures 1 to 2 The feeding assembly includes a second support bracket 9. A baffle 10 is fixedly connected inside the second support bracket 9, and a feed inlet 11 is fixedly connected to the bottom end of the baffle 10. The design of the feed inlet 11 ensures that the raw materials can quickly and accurately enter the next processing stage. A rotating shaft 12 is rotatably connected inside the second support bracket 9, and a conveyor belt 13 is rotatably connected to the outside of the rotating shaft 12. Multiple feeding hoppers 14 are fixedly connected to the outside of the conveyor belt 13. The feeding hoppers 14 are made of wear-resistant plastic to ensure stability and durability during long-term use. Another rotating shaft 12 is rotatably connected inside the conveyor belt 13. A third support bracket 16 is rotatably connected to the left end of each rotating shaft 12. The third support bracket 16 is made of high-strength steel to ensure safety and durability during support and rotation. A second motor 15 is fixedly connected to the left end of the third support bracket 16, ensuring stable operation of the system over a long period.
[0036] A feed bracket 19 is fixedly connected to the top of the support bracket 16. The feed bracket 19 serves as a support structure, ensuring the stability of the feed and avoiding errors caused by uneven material flow or mechanical vibration. A funnel 17 is fixedly connected to the top of the feed bracket 19. The funnel 17 has an optimized design shape, allowing the material to flow smoothly and efficiently downwards, reducing the risk of blockage. A ramp 18 is fixedly connected to the bottom of the funnel 17. The angle and material of the ramp 18 are precisely calculated to ensure that the material can smoothly slide into the feeding hopper 14 under gravity. When polycarbonate resin injection molding is required, the worker pours the material into the funnel 17. The material then enters the ramp 18 through the funnel 17 and falls into the feeding hopper 14. The ramp 18 not only reduces friction but also effectively prevents the material from accumulating during the flow process.
[0037] Motor 15 is started, driving shaft 12 to rotate. Shaft 12 drives conveyor belt 13 to rotate, which in turn drives hopper 14 to move upward. Simultaneously, conveyor belt 13 drives another shaft 12 to rotate inside bracket 9, limiting the movement of conveyor belt 13. This limiting design prevents material leakage or waste caused by excessive rotation of conveyor belt 13. When hopper 14 reaches the top of conveyor belt 13, it changes direction with the movement of conveyor belt 13, pouring the material into inlet 11. At the same time, baffle 10 blocks the material to prevent leakage, ensuring that the material enters transfer port 23 accurately.
[0038] Reference Figure 1 and Figure 4 The injection molding assembly includes a hydraulic press 20, with a motor 21 fixedly connected to the right end of the hydraulic press 20. A feeding shaft 22 is fixedly connected to the front end of the motor 21, and a transfer port 23 is rotatably connected to the outside of the feeding shaft 22. These components are made of high-strength materials to ensure long-term stable operation of the system and reduce wear. A heating cylinder 24 is fixedly connected to the left end of the transfer port 23, and a heating tube 25 is fixedly connected inside the heating cylinder 24 to provide uniform and stable heat to ensure that the polycarbonate resin is not damaged during heating. A fixed mold 26 is fixedly connected to the right end of the heating cylinder 24. The fixed mold 26 is designed with high-temperature and pressure-resistant stainless steel to ensure that it can still work accurately under high temperature and pressure. A limit shaft 27 is slidably connected inside the fixed mold 26. The limit shaft 27 ensures the stability of the mold position during injection molding through a sliding structure. A moving mold 28 is fixedly connected to the right end to ensure smooth and precise mold movement. The bottom end of the fixed mold 26 is fixedly connected to the top of the base 1. The base 1 is made of cast steel and has good pressure resistance to ensure the stability of the entire feeding system.
[0039] A hydraulic press 29 is fixedly connected to the top of the base 1. The hydraulic press 29 has a robust structure and can quickly respond to control signals to precisely push the mold. The cooling assembly includes a coolant tank 33, with a water pump 32 fixedly connected to its rear end. The water pump 32 provides a strong coolant flow rate to ensure the cooling and shaping of the injection molded product. A hose 31 is fixedly connected to the output end of the water pump 32. The hose 31 is made of rubber, capable of withstanding high-temperature and high-pressure coolant flow while exhibiting good deformation recovery. A conduit 30 is fixedly connected to the top of the hose 31. The conduit 30's tortuous structure ensures the coolant flows smoothly to the required location. A hose 34 is fixedly connected to the front end of the conduit 30. The hose 34 precisely delivers coolant to the moving mold 28, helping to reduce the mold temperature and prevent overheating.
[0040] Handles are installed at both the front and rear ends of the collection box 8, making it convenient for workers to clean and transport waste materials at any time. The drive end of motor 2 15 is fixedly connected to the right end of another rotating shaft 12. The rotating shaft 12 is made of high-quality steel to ensure high transmission efficiency and stability. The bottom end of bracket 2 9 is fixedly connected to the top of base 1, providing strong structural support and ensuring the stability of feeding. The bottom end of motor 3 21 is slidably connected inside base 1, enabling smooth and quick adjustment of the position of the feeding shaft 22. The bottom end of motion mold 28 is slidably connected to the top of base 1 to ensure precise mold alignment and prevent errors during operation.
[0041] Working Principle: When polycarbonate resin injection molding is required, the worker pours the raw material into the funnel 17. The raw material enters the inclined plane 18 through the funnel 17 and falls into the feeding hopper 14. Motor 15 is started, driving the rotating shaft 12 to rotate. The rotating shaft 12 drives the conveyor belt 13 to rotate, which in turn moves the feeding hopper 14 upwards. Simultaneously, the conveyor belt 13 drives another rotating shaft 12 to rotate inside the support 9, limiting the movement of the conveyor belt 13. When the feeding hopper 14 reaches the top of the conveyor belt 13, it changes direction with the movement of the conveyor belt 13, pouring the raw material into the inlet 11. At the same time, the baffle 10 blocks the material to prevent leakage.
[0042] Raw materials enter the transfer port 23 through the feed port 11. The motor 21 is started, and the motor 21 drives the feeding shaft 22 to rotate inside the transfer port 23. While the feeding shaft 22 is rotating, the external spiral blades transport the contents of the transfer port 23 forward to the interior of the heating cylinder 24. At the same time, the raw materials inside the heating cylinder 24 are heated through the heating tube 25. When the feeding shaft 22 transports the raw materials to the right end of the heating tube 25, the hydraulic press 29 is started. The hydraulic press 29 drives the moving mold 28 to move to the left until it is attached to the right end of the fixed mold 26. At this time, the hydraulic press 20 is started, and the hydraulic press 20 drives the motor 21 to slide to the right. The motor 21 drives the feeding shaft 22 to move to the right. The feeding shaft 22 injects the raw materials inside the heating cylinder 24 into the interior of the fixed mold 26 and the moving mold 28 through the cone at the right end.
[0043] At this time, water pump 32 is started, and water pump 32 delivers the coolant inside the coolant tank 33 to the inside of hose 31. Through hose 31, the coolant is delivered to the inside of conduit 30, and through conduit 30, it enters hose 34. The coolant inside conduit 30 cools the material at the left end of the moving mold 28. After cooling is completed, hydraulic press 29 is started again, and hydraulic press 29 drives the moving mold 28 to slide to the right. At this time, the workers collect the cooled product and recycle the waste.
[0044] When recycling waste, workers throw the waste into the space between roller 4 and roller 5, start motor 3, and motor 3 drives gear 6 to rotate inside bracket 2. Gear 6 drives roller 5 to rotate inside bracket 2. Gear 6 meshes with gear 7 to drive gear 7 to rotate inside bracket 2. Gear 7 drives roller 4 to rotate inside bracket 2. Roller 4 and roller 5 rotate relative to each other, crushing the waste and sending the processed waste into the collection box 8. When the processed waste accumulates in the collection box 8, the waste inside the collection box 8 is transported through the handles at both ends of the collection box 8.
[0045] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
