Description

Technical Field

[0001] The present invention relates to the technical field of injection molds, and specifically relates to a cooling device for automotive injection molds. Background Art

[0002] An injection mold is a tool for producing plastic products; it is also a tool for giving plastic products a complete structure and precise dimensions. Injection molding is a processing method used when mass-producing some complex-shaped parts. Specifically, it means injecting the heat-melted plastic into the mold cavity under high pressure by an injection molding machine, and after cooling and solidifying, the formed product is obtained. Injection molds are required in the automotive field, and when the injection mold is used up, it needs to be cooled in time.

[0003] A cooling device for an injection mold with uniform cooling, with the publication number CN215825888U, can facilitate the use of a water pump, a water supply pipe, and a connecting pipe through the use of a "mouth"-shaped condensing pipe, and can conveniently perform circulating cooling on the outer surface of the lower mold. There are three groups of condensing pipes arranged on the outside of the lower mold, which can conveniently improve the uniform cooling of the device and the cooling effect of the device.

[0004] When in use, there are still some deficiencies. When in use, it can only cool the inside of the injection mold and cannot cool the outside of the injection mold, reducing the cooling effect and rate of the injection mold, resulting in a high surface temperature of the injection mold that cannot be cooled in time, and further causing damage to the injection mold. At the same time, when cooling the injection mold, water will splash to the outside, making the cooling device in a humid environment and reducing the practicability of the cooling device when in use.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] For the embodiments, please refer to Figures 1 - 6 , the present invention provides a technical solution:

[0029] A cooling device for an automotive injection mold, including a fixing plate 31. A fixing box 4 is fixedly connected to the top of the fixing plate 31. A driving motor 9 is installed on the side of the fixing box 4. The output end of the driving motor 9 is fixedly connected to a rotating plate 28. A suction plate 29 is fixedly connected inside the rotating plate 28. The top of the suction plate 29 abuts against a mold cavity 30. A weighing device 18 is fixedly connected to the surface of the fixing box 4. The mold cavity 30 is abutted against the surface of the suction plate 29. Then, the side cover 5 is closed, and water in a water tank 10 is sprayed into the mold cavity 30 through a spray pipe 12 by a water pump 11. The water in the water tank 10 is cooled by ice cubes 19, and thus the inside of the mold cavity 30 can be cooled. When the water in the water tank 10 gradually decreases, the water tank 10 can be weighed by the weighing device 18. When the water in the water tank 10 decreases to a certain weight, information is transmitted to an alarm lamp 7 through a control board 8 to make the alarm lamp 7 flash. The top of the weighing device 18 abuts against the water tank 10. Ice cubes 19 are abutted inside the water tank 10. The top of the water tank 10 abuts against a cover plate 13. A pull ring 14 is fixedly connected to the top of the cover plate 13. A water pump 11 is installed on the side of the water tank 10. A spray pipe 12 is fixedly connected to the side of the water pump 11. The spray pipe 12 is arranged directly above the mold cavity 30. An alarm lamp 7 is fixedly connected to the side of the fixing box 4.

[0030] In this embodiment, as shown in Figure 1 , Figure 2 and Figure 3 , a control board 8 is fixedly connected to the top of the fixing box 4. The weighing device 18 is electrically connected to the control board 8. The control board 8 is electrically connected to the alarm lamp 7. Heat dissipation holes 6 are opened inside the fixing box 4. A vertical plate 16 is fixedly connected to the side of the fixing box 4. A rectangular plate 20 is slidably connected inside the vertical plate 16. An air pump 22 is installed on the top of the rectangular plate 20. One end of the air pump 22 is fixedly connected to a screen 21. The other end of the air pump 22 is fixedly connected to a spray head 23. The spray head 23 is communicated with the screen 21. A collar 24 is fixedly connected to the bottom of the rectangular plate 20. The inner wall of the collar 24 is fixedly connected with first teeth 25.

[0031] Among them, the water in the water tank 10 can be cooled by the ice block 19, and then the cooled water is sent into the interior of the mold cavity 30 through the spray pipe 12 by the water pump 11 to cool the interior of the mold cavity 30. At the same time, the external gas is sprayed onto the outer surface of the mold cavity 30 through the nozzle 23 by the air pump 22, and the rectangular plate 20 and the nozzle 23 are driven to move up and down in a cycle under the power of the stepping motor 27 to cool the outer surface of the mold cavity 30. By cooling the interior and exterior of the mold cavity 30 simultaneously, the cooling rate of the mold cavity 30 can be increased.

[0032] In this embodiment, as Figure 4 , Figure 5 and Figure 6 shown, a stepping motor 27 is installed outside the fixed box 4. The output end of the stepping motor 27 is fixedly connected to a second tooth 26, and the second tooth 26 extends into the collar 24. The second tooth 26 meshes with the first tooth 25. The nozzle 23 is arranged on the side of the mold cavity 30, and the shape of the nozzle 23 is conical. The external gas is sent into the nozzle 23 through the screen 21 by the air pump 22 and sprayed onto the outer surface of the mold cavity 30. When the stepping motor 27 works, it drives the second tooth 26 to rotate. Since the second tooth 26 and the first teeth 25 on the left and right inner walls of the collar 24 mesh in a cycle, the rectangular plate 20 and the nozzle 23 can be driven to move up and down in a cycle to cool the outside of the mold cavity 30, improving the cooling effect and rate of the mold cavity 30. A side cover 5 is rotatably connected to the outside of the fixed box 4 through a hinge 15. The side cover 5 is arranged on the side of the fixed box 4. Through holes 17 are formed in both the fixed box 4 and the fixing plate 31. The bottom of the fixing plate 31 is fixedly connected to a bottom plate 1. A water collecting box 3 abuts against the surface of the bottom plate 1. Universal wheels 2 are arranged at the bottom of the bottom plate 1, and the universal wheels 2 are movably connected to the bottom plate 1. A plurality of first teeth 25 are provided, and the plurality of first teeth 25 are equally spaced in the collar 24, and the sizes of the plurality of first teeth 25 are the same.

[0033] Among them, the mold cavity 30 can be adsorbed and fixed by the suction plate 29. When the mold cavity 30 is cooled, the driving motor 9 drives the rotating plate 28 and the mold cavity 30 to rotate, so as to pour out the water inside the mold cavity 30, and the water enters the water collecting box 3 through the through hole 17 for collection, improving the external environment during the cooling of the mold cavity 30.

[0034] Working process of the present invention: When the cooling device for automotive injection molds designed by this solution is working, the mold cavity 30 is abutted against the surface of the suction plate 29, then the side cover 5 is closed, and the water in the water tank 10 is sprayed into the interior of the mold cavity 30 through the spray pipe 12 by the water pump 11. The water in the water tank 10 is cooled by the ice block 19, and then the interior of the mold cavity 30 can be cooled. When the water in the water tank 10 gradually decreases, the water tank 10 can be weighed by the weighing device 18. When the water in the water tank 10 decreases to a certain weight, the control board 8 transmits the information to the alarm lamp 7 to make the alarm lamp 7 flash. At the same time, the external gas enters the nozzle 23 through the screen 21 by the air pump 22 and is sprayed onto the outer surface of the mold cavity 30. When the stepping motor 27 works, it drives the second tooth 26 to rotate. Since the second tooth 26 and the first teeth 25 on the inner walls of the left and right sides of the collar 24 are engaged in a cycle, the rectangular plate 20 and the nozzle 23 can be driven to move up and down in a cycle to cool the outside of the mold cavity 30, improving the cooling effect and rate of the mold cavity 30. When the cooling of the mold cavity 30 is completed, the switches of all external electrical appliances are turned off, and the nozzle 23 is moved to the inner top wall of the fixed box 4. Then, the driving motor 9 drives the rotating plate 28 and the mold cavity 30 to rotate, making the mold cavity 30 tilt, and then the water in the mold cavity 30 flows through the through hole 17 into the water collecting box 3 for collection, completing the cooling work of the mold cavity 30. Then, the side cover 5 is opened and the mold cavity 30 is taken out from the rotating plate 28.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
