[0020] 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.

[0021] Please see Figure 1-4 This utility model provides an embodiment of an injection mold for high-transmittance composite coating of aspherical lenses, including a lower mold base 1 and an upper mold base 6. The upper mold base 6 is provided at the top of the lower mold base 1. A mounting bracket 4 is fixedly installed on the outer side of the top of the lower mold base 1, and a mounting plate 9 is horizontally arranged between the two sides inside the mounting bracket 4. Liquid distribution pipes 10 are horizontally fixed at the rear ends of the top and bottom of the mounting plate 9, and a plurality of nozzles 11 are fixedly installed on the liquid distribution pipes 10. A servo motor 24 is fixedly installed at the rear end of the right side of the mounting bracket 4, and a controller 23 is fixedly installed on the right side of the rear end of the mounting bracket 4. The middle position of the rear end of the mounting bracket 4 is... A water pump 22 is installed and fixed at the location, and a water outlet pipe 21 is installed and fixed at the output end of the water pump 22. A tee 20 is installed and fixed at the front end of the water outlet pipe 21, and a hose 19 is installed and fixed at the top and bottom of the front end of the tee 20. Screws 25 are movably installed on both sides inside the mounting frame 4, and threaded sleeves 26 are threaded to the outside of the screws 25. The rear ends of the two sets of screws 25 pass through the rear end of the mounting frame 4 and are fixed with bevel gears 27. A connecting shaft 29 is movably installed laterally inside the rear end of the mounting frame 4, and bevel gears 28 are fixed on both sides outside the connecting shaft 29.

[0022] The right side of the left threaded sleeve 26 passes through the left side of the mounting bracket 4 and is fixedly connected to the left side of the mounting plate 9. The left side of the right threaded sleeve 26 passes through the right side of the mounting bracket 4 and is fixedly connected to the right side of the mounting plate 9. The right side of the connecting shaft 29 passes through the inside of the right side of the mounting bracket 4. The output shaft of the servo motor 24 is fixedly connected to the right side of the connecting shaft 29. The bevel gear 28 and the bevel gear 27 are meshed. Several nozzles 11 are evenly distributed on the liquid distribution pipe 10. The front ends of the two sets of hoses 19 are fixedly connected to the rear ends of the two sets of liquid distribution pipes 10 respectively. A liquid extraction pipe is installed and fixed at the input end of the water pump 22. The liquid distribution pipe 10 and the nozzles 11 are symmetrically arranged about the horizontal center line of the mounting plate 9.

[0023] Specifically, such as Figures 1-4 As shown, after the water pump 22 is connected to the liquid storage tank for coating, before the upper mold base 6 and the lower mold base 1 are closed, the water pump 22 can be started to draw the coating liquid in and deliver it into the interior of the upper and lower component liquid pipes 10 through the water outlet pipe 21, the three-way valve 20 and the hose 19. It can also be atomized and sprayed onto the outer side of the upper mold body 8 and the inner side of the mold cavity 12 through several nozzles 11. At the same time, the servo motor 24 can be started to drive the connecting shaft 29 to rotate. When the connecting shaft 29 rotates, the meshing bevel gear 28 and bevel gear 27 can drive the left and right sets of lead screws 25 to rotate synchronously. When the lead screws 25 rotate, the threaded sleeve 26 can drive the mounting plate 9 to move forward inside the mounting frame 4, and at the same time drive the upper and lower nozzles 11 to move forward. The coating liquid can be evenly sprayed onto the outer side of the upper mold body 8 and the inner side of the mold cavity 12. Then, the mold is closed and injection molding is performed, which reduces the time spent on the subsequent coating processing steps.

[0024] The top and bottom front ends of the mounting plate 9 are respectively horizontally fixed with air distribution pipes 13, and several nozzles 14 are fixed on the air distribution pipes 13.

The front end of the air outlet pipe 17 is fixed with a tee 16, and the top and bottom of the front end of the tee 16 are respectively fixed with hoses 15. Several nozzles 14 are evenly distributed on the air distribution pipes 13. The air distribution pipes 13 and nozzles 14 are symmetrically arranged about the horizontal center line of the mounting plate 9. The front ends of the two sets of hoses 15 are respectively fixed between the left side of the two sets of air distribution pipes 13.

[0025] Specifically, such as Figures 1-4 As shown, the air pump 18 can be controlled to start pressurizing air, and the pressurized air can be delivered into the interior of the upper and lower air groups 13 through the air outlet pipe 17, the three-way valve 2 16 and the hose 2 15. Several nozzles 2 14 can spray out on the outside of the upper mold body 8 and the inside of the mold cavity 12. During the back and forth movement of the mounting plate 9, the surface of the mold can be cleaned by auxiliary blowing.

[0026] Two sets of fixing seats 2 are fixed to the front and back on both sides of the lower mold base 1, and a guide post 3 is fixed vertically at the top of the fixing seat 2. Two sets of sliding sleeves 5 are fixed to the front and back on both sides of the upper mold base 6. The guide post 3 passes through the interior of the sliding sleeve 5. An injection port 7 is provided at the top of the upper mold base 6. An upper mold body 8 is fixed at the bottom of the upper mold base 6. A mold cavity 12 is provided inside the top of the lower mold base 1.

[0027] Working principle: When the mold is installed and used, after the liquid extraction pipe of the water pump 22 is connected to the storage tank of the coating liquid, before the upper mold base 6 and the lower mold base 1 are closed, the water pump 22 can be started to draw in the coating liquid and deliver it into the interior of the upper and lower component liquid pipes 10 through the water outlet pipe 21, the three-way valve 20 and the hose 19. It can also be atomized and sprayed onto the outer side of the upper mold body 8 and the inner side of the mold cavity 12 through several nozzles 11. At the same time, the servo motor 24 can be started to drive the connecting shaft 29 to rotate. When the connecting shaft 29 rotates, the meshing bevel gear 28 and bevel gear 27 can drive the left and right sets of lead screws 25 to rotate synchronously. When the lead screws 25 rotate, the threaded sleeve 26 can drive the mounting plate 9 to move forward inside the mounting frame 4, and at the same time drive the upper and lower nozzles 11 to move forward, so that the coating liquid can be evenly sprayed onto the outer side of the upper mold body 8 and the inner side of the mold cavity 12. After that, the mold can be closed and injection molding can be carried out, which is a high-efficiency injection molding production process. Simultaneously, before the film liquid spraying treatment, the air pump 18 can be controlled to start pressurizing air, and the pressurized air is delivered into the interior of the upper and lower air pipes 13 through the air outlet pipe 17, the three-way valve 2 16 and the hose 2 15. Several nozzles 2 14 can spray out on the outside of the upper mold body 8 and the inside of the mold cavity 12. During the back and forth movement of the mounting plate 9, the surface of the mold can be assisted by blowing and cleaning.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
