Description
Technical Field
[0001] This utility model relates to the technical field of automotive air conditioning production, and in particular to a mold for manufacturing the exhaust fan impeller of an automotive air conditioning system. Background Technology
[0002] With the continuous development of the automotive industry and people's increasing demands for vehicle comfort, automotive air conditioning systems, as an important component for enhancing the driving experience, have become one of the standard features in automobiles. The air conditioning fan impeller, as a crucial component of the air conditioning system, directly affects the efficiency of the air conditioning system and the air circulation within the vehicle.
[0003] Traditional air conditioning ventilation fan impeller manufacturing methods mainly rely on mold injection molding. Molten raw materials are injected into the mold cavity through the nozzle of the injection molding machine. The plastic raw materials cool and solidify in the mold cavity to form the shape of the impeller. However, in actual use, most fan impellers in the mold require manual demolding after cooling and forming, which is not only inefficient but also poses certain safety hazards. Therefore, a new mold for manufacturing automotive air conditioning ventilation fan impellers is proposed to solve the above problems. Utility Model Content

[0030] 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.
[0031] Reference Figure 1 , Figure 4 , Figure 5 and Figure 6This utility model provides an embodiment of a mold for manufacturing an automotive air conditioning ventilation fan impeller, comprising a mold blank panel 1, a stripper plate 3 fixedly connected to the bottom of the mold blank panel 1, a telescopic cylinder 4 fixedly connected to the bottom of the mold blank panel 1, a mold blank plate 5 fixedly connected to the output end of the telescopic cylinder 4, a support frame 6 fixedly connected to the bottom of the mold blank plate 5, a mold blank base plate 10 fixedly connected to the bottom of the support frame 6, an injection molding assembly installed between the stripper plate 3 and the mold blank plate 5, an ejector base plate 9 fixedly connected to the top of the mold blank base plate 10, an ejector plate 8 slidably connected to the middle of the ejector base plate 9, and a reset assembly installed between the ejector plate 8 and the mold blank plate 5. The reset assembly includes an ejector rod 18 fixedly connected to the ejector plate 8. The top of the ejector plate 8 is fixedly connected to a reset rod 7. The other end of the reset rod 7 is slidably connected to the middle of the mold base plate 1 5. A tension spring 19 is installed between the ejector plate 8 and the mold base plate 1 5. The injection molding assembly includes a mold base plate 2 13. The mold base plate 2 13 is fixedly connected to the bottom of the stripper plate 3. Mold cores 12 are fixedly connected to the middle of both the mold base plate 2 13 and the mold base plate 1 5. A lower mold 15 is fixedly connected to the top of one of the mold cores 12. A fan impeller body 17 is provided between the lower mold 15 and the other mold core 12. The end of the ejector rod 18 away from the ejector plate 8 passes through the mold base plate 1 5 and one of the mold cores 12 from bottom to top and is slidably connected to the lower mold 15. A nozzle 2 is fixedly connected between the mold base plate 1 and the stripper plate 3. First, the opening / closing device 11 drives the telescopic cylinder 4 to move the mold base plate 1 downwards. This causes the mold base plate 1 to move together with the mold base plate 2 13 via the stripper plate 3, so that the mold base plate 2 13 can merge with the mold core 12. At the same time, when the mold base plate 2 13 merges with the mold base plate 1 5, it pushes the ejector rod 18, causing the ejector rod 18 to slide the ejector pin base plate 9 in the middle of the ejector pin plate 8. While the ejector pin plate 8 is sliding, it pulls the tension spring 19, thereby allowing plastic raw material to be fed into the two mold cores 12 through the nozzle 2. Between and under the action of the lower mold 15, the plastic material is plasticized and formed into the fan impeller body 17 after cooling. After forming, the telescopic cylinder 4 drives the mold blank panel 1 to rise again, so that the two mold cores 12 separate. At the same time, the ejector rod 18 is no longer squeezed, so under the action of the tension spring 19, the ejector pin base plate 9 is pulled to reset, and then the ejector rod 18 is reset, pushing the formed fan impeller body 17 out of the lower mold 15. This allows for quick and automatic demolding, which improves work efficiency and avoids the safety hazards caused by manual demolding.
[0032] Reference Figures 2-6 The tension spring 19 is sleeved on the outer periphery of the reset rod 7. The reset rod 7 can improve the stability of the tension spring 19 during extension and retraction, and prevent displacement.
[0033] Reference Figures 2-4A sprue hook 14 is installed in the middle of the mold base panel 1. The other end of the sprue hook 14 passes through the stripper plate 3 and the mold base plate 13 from top to bottom. The sprue hook 14 can hook out the solidified material in the runner or the gate residue after mold opening, so that the staff can clean it.
[0034] Reference Figures 2-4 A telescopic rod 16 is fixedly connected to the middle of the mold base plate 5. The other end of the telescopic rod 16 passes through the stripper plate 3 and the mold base panel 1 from bottom to top. An opening and closing device 11 is fixedly connected to the top of the mold base plate 5. The stability of the mold base panel 1 and the stripper plate 3 during movement can be improved by using the sprue hook 14.
[0035] Working principle: When the telescopic cylinder 4 drives the two mold cores 12 to merge, one of the mold cores 12 will squeeze the ejector rod 18. At the same time, the ejector rod 18 pulls the tension spring 19 through the ejector pin base plate 9. After the raw material in the mold cools and forms, the telescopic cylinder 4 drives the two mold cores 12 to separate. At the same time, the tension spring 19 will pull the ejector pin panel 8 to reset the ejector rod 18, thereby ejecting the formed fan impeller body 17 from the lower mold 15.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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.
