[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.
[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0020] See also Figure 1-3 In the present invention, an air-conditioning motor stator injection mold includes a valve needle base plate 1, a valve needle fixing plate 2 is arranged below the valve needle base plate 1, a valve needle body 6 is arranged on the valve needle base plate 1 and the valve needle fixing plate 2, and the valve needle body 6 is made of high-strength and corrosion-resistant material to ensure that during a long-term and high-frequency injection molding process, the valve needle body 6 can maintain the integrity of its shape and function and is not easy to wear or deform.
[0021] A flow channel cover plate 3, a main flow channel plate 4 and a branch flow channel plate 5 are arranged below the valve needle body 6, and an upper mold core 7 and a lower mold core 8 are arranged below the branch flow channel plate 5. The bottom end of the valve needle body 6 passes through the flow channel cover plate 3, the main flow channel plate 4 and the branch flow channel plate 5 in sequence and extends to the top of the upper mold core 7. A temperature control system is arranged between the main flow channel plate 4 and the branch flow channel plate 5. The system can accurately control the temperature of the melt in the flow channel to ensure that the melt maintains appropriate fluidity and viscosity during the injection molding process, thereby improving the quality and production efficiency of the injection molded products. At the same time, the flow channel cover plate 3, the main flow channel plate 4 and the branch flow channel plate 5 together constitute the flow path of the melt. When the melt reaches between the upper mold core 7 and the lower mold core 8, the matching mold cavity shapes of the two molds the melt into the desired product shape. The valve needle body 6 extends to the top of the upper mold core 7, accurately controls the melt flow during the injection molding process, and ensures that the final characteristics of the product hole are consistent with the shape of the valve needle body 6.
[0022] The upper mold core 7 and the lower mold core 8 are adapted to each other, ensuring the close fit and high consistency of the two when the molds are closed. Such adaptability can not only effectively prevent leakage of materials during the injection molding process, but also ensure the uniform distribution of injection pressure, thereby accurately controlling the shape, size and internal structure of the air-conditioning motor stator, and comprehensively ensuring the quality of the air-conditioning motor stator injection molding, meeting high-precision manufacturing requirements, and improving the overall performance and durability of the product.
[0023] A cooling box 11 is provided below the lower mold core 8, and a group of equidistantly arranged heat-conducting rods 10 are embedded inside the lower mold core 8. The bottom end of each heat-conducting rod 10 extends into the cooling box 11. By providing the heat-conducting rods 10, the heat inside the lower mold core 8 can be conducted to the cooling box 11.
[0024] A pump body 13 is installed on the front of the cooling box 11. The input end of the pump body 13 is connected to the front of the cooling box 11 through a water pumping pipe 12. The output end of the pump body 13 is fixedly connected to a water supply pipe 14. The output end of the water supply pipe 14 extends to the inner wall of the cooling box 11 and is connected to a water collecting pipe 15. The outer surface of the water collecting pipe 15 is connected to a group of nozzles 17 arranged at equal distances. By working of the pump body 13, the water inside the cooling box 11 will enter the water collecting pipe 15, and the nozzle 17 will spray water onto the heat conducting rod 10, thereby accelerating the cooling of the heat conducting rod 10. The heat conducting rod 10 will continue to absorb and conduct heat inside the lower mold core 8, and the molding speed of the injection molded product will be accelerated, thereby improving the injection molding efficiency.
[0025] Two suspension rods 16 are fixedly connected to the outer surface of the water collecting pipe 15, and the top of each suspension rod 16 is connected to the inner top wall of the cooling box 11. The suspension rods 16 can be used to stabilize the water collecting pipe 15 and the nozzle 17, thereby ensuring that the nozzle 17 continuously sprays water to the heat conducting rod 10 to dissipate heat.
[0026] The left and right sides of the cooling box 11 are both provided with heat dissipation grooves 9 , which can be used to dissipate the heat inside the cooling box 11 , further improving the heat conduction effect of the heat conducting rod 10 .
[0027] A base 9 is provided below the lower mold core 8, and an anti-slip protrusion is provided at the bottom of the base 9. The upper surface of the base 9 is connected to the bottom surface of the cooling box 11. By utilizing the provided base 9, the device can obtain stable and reliable support, which can not only effectively disperse and withstand various forces generated during the injection molding process, but also significantly enhance the stability of the overall structure, thereby ensuring that the air-conditioning motor stator can be smoothly injected during the injection molding operation, greatly improving the injection molding accuracy and yield rate, and providing a solid guarantee for the production of high-quality and high-performance air-conditioning motor stators.
[0028] The working principle of the present application is as follows: during the injection molding process, the melt is injected into the mold from the nozzle of the injection molding machine, first flowing through the valve needle body 6, and then the melt passes through the runner cover plate 3, the main runner plate 4 and the branch runner plate 5. These plates together constitute the flow path of the melt. When the melt reaches between the upper mold core 7 and the lower mold core 8, the matching mold cavity shapes of the two mold the melt into the desired product shape. The valve needle body 6 extends to the top of the upper mold core 7 to accurately control the melt flow during the injection molding process to ensure that the final characteristics of the product hole are consistent with the shape of the valve needle body 6. At the same time, during injection molding, the heat conducting rod 10 will absorb and conduct the heat inside the lower mold core 8, and then control the pump body 13 to work. The pump body 13 will pump the water inside the cooling box 11, and the water will enter the water collecting pipe 15 from the pumping pipe 12 and the water pipe 14. The nozzle 17 will spray the water onto the heat conducting rod 10, thereby accelerating the heat dissipation of the lower mold core 8, allowing the injection molded product to be quickly formed, thereby improving the injection molding efficiency.
[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
