Description

Technical Field

[0001] This utility model relates to the field of mold cooling technology, and in particular to a mold cooling device for a vacuum forming machine. Background Technology

[0002] Cooling the mold after thermoforming is mainly to lower the mold temperature so that the formed product can be safely removed, preventing deformation and damage. Simply put, cooling is a key step to ensure the stability and safety of the mold and the product.

[0003] A search revealed a Chinese patent with authorization number CN214214733U, which discloses a thermostatic device for a thermoforming machine mold. The device includes a mold and a cooling device. A temperature sensor is installed inside the mold, and the cooling device is located above the mold with its air outlet facing the mold. It also includes a temperature controller. The signal output terminal of the temperature sensor is electrically connected to the signal input terminal of the temperature controller, and the input terminal of the cooling device is electrically connected to the output terminal of the temperature controller. When the molded product is removed from the mold and the temperature of the mold is higher than the set temperature of the temperature controller, the temperature controller activates the cooling device.

[0004] The thermostatic device for a vacuum forming machine mold in the aforementioned patent has the following shortcomings: the range of air blowing from the four air outlets is limited, and some areas of the mold may not be cooled sufficiently, resulting in inconsistent temperatures. During the cooling process, the position of the four air outlets needs to be adjusted by the staff multiple times to achieve comprehensive cooling of the mold, which increases the frequency of adjustment by the staff, is cumbersome, and may lead to errors. Therefore, it is necessary to design a cooling device for a vacuum forming machine mold to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a cooling device for vacuum forming machine molds.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cooling device for a vacuum forming machine mold includes a cooling box. A top cover is fixedly connected to the inner wall of the top of the cooling box. A vacuum forming machine mold is fixedly connected to the inner wall of the top cover. Heat dissipation fins are fixedly connected to the outer walls of the four sides of the vacuum forming machine mold. A pipe is fixedly connected to the outer wall of the cooling box. Four output ends are provided on the pipe. Each of the four output ends of the pipe is fixedly connected to a nozzle. The four nozzles are respectively fixedly connected to the inner walls of the four sides of the cooling box. A funnel is fixedly connected to the bottom of the cooling box. A square tube is fixedly connected to the bottom of the funnel. A rubber sealing gasket is fixedly connected to the bottom of the square tube. A filter plate is provided at the bottom of the rubber sealing gasket. Four positioning rods are passed through the filter plate. The four positioning rods are fixedly connected to the bottom of the funnel. Two sleeves are fixedly connected to the top of one end of the filter plate. Two sleeves are fixedly connected to the outer wall of one side of the square tube. Magnets are fixedly connected to the inner walls of the sleeves. The mold and the sleeve are connected by the same metal rod. The heat is transferred to the heat dissipation fins using a vacuum forming mold, and then water is sprayed onto the fins for cooling. This increases the heat dissipation area, and the water sprayed from the nozzles cools the fins. The water is then filtered through a filter plate for reuse. The metal rod, sleeve, sleeve, and magnet work together to restrict the position of the filter plate. Removing the metal rod releases the restriction, facilitating cleaning of the filter plate. This effectively solves the problem in the background technology where the four air outlets have limited airflow range, resulting in insufficient cooling in some areas of the mold and inconsistent temperatures. It also addresses the need for operators to repeatedly adjust the positions of the four air outlets to achieve comprehensive cooling. This method achieves uniform, comprehensive, and efficient mold cooling, reducing manual operation, simplifying the process, and saving time and labor costs.

[0008] As a further embodiment of this utility model, four support rods are fixedly connected to the bottom of the funnel, and the bottoms of the four support rods are fixedly connected to the same base.

[0009] As a further embodiment of this invention, a temperature sensor is provided at the bottom of the vacuum forming machine mold.

[0010] As a further embodiment of this utility model, the temperature sensor is electrically connected to a temperature controller via a wire, and the temperature controller is fixedly connected to the top of the base.

[0011] As a further embodiment of this utility model, a water pump and a PLC programmable controller are fixedly connected to the top of the base, and the PLC programmable controller is electrically connected to the water pump and the temperature controller through wires.

[0012] As a further embodiment of this utility model, a water tank is fixedly connected to the top of the base.

[0013] As a further embodiment of this utility model, a first water pipe is provided inside the water tank, the first water pipe is connected to the input end of the water pump, and a second water pipe is fixedly connected to the output end of the water pump, the second water pipe being fixedly connected to a pipeline.

[0014] The beneficial effects of this utility model are as follows:

[0015] By employing a vacuum forming mold to conduct heat to the heat dissipation fins, and then spraying water to cool the fins, the heat from the vacuum forming mold is transferred to the heat dissipation fins, increasing the heat dissipation area. The water sprayed from the nozzles cools the heat dissipation fins, and then the water is filtered through a filter plate for reuse. The position of the filter plate can also be restricted by the cooperation of a metal rod, a sleeve, a sleeve, and a magnet. Pulling out the metal rod releases the restriction, making it easy to clean the filter plate. This effectively solves the problem mentioned in the background technology that the air blowing range of the four air outlets is limited, and some areas of the mold may not be cooled sufficiently, resulting in inconsistent temperatures. It also solves the problem that the position of the four air outlets needs to be adjusted by the staff multiple times during the cooling process to achieve comprehensive cooling of the mold. This achieves uniform, comprehensive, and efficient mold cooling, reduces manual operation, simplifies the operation process, and saves time and labor costs. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-6 A cooling device for a vacuum forming machine mold includes a cooling box 1. A top cover 2 is fixedly connected to the inner wall of the top of the cooling box 1. A vacuum forming machine mold 3 is fixedly connected to the inner wall of the top cover 2. Heat dissipation fins 4 are fixedly connected to the outer walls of the four sides of the vacuum forming machine mold 3. A pipe 5 is fixedly connected to the outer wall of the cooling box 1. Four output ends are provided on the pipe 5. Each of the four output ends of the pipe 5 is fixedly connected to a nozzle 6. The four nozzles 6 are respectively fixedly connected to the inner walls of the four sides of the cooling box 1. A funnel 7 is fixedly connected to the bottom of the cooling box 1. A square tube 8 is fixedly connected to the bottom of the funnel 7. A rubber sealing gasket 9 is fixedly connected to the bottom of the square tube 8. A filter plate 10 is provided at the bottom of the rubber sealing gasket 9. Four positioning rods 11 are passed through the filter plate 10. The four positioning rods 11 are fixedly connected to the bottom of the funnel 7. Two sleeves 12 are fixedly connected to the top of one end of the filter plate 10. Two sleeves 13 are fixedly connected to the outer wall of one side of the square tube 8. A magnet 14 is fixedly connected to the inner wall of the sleeve 13. The cylinder 13 and the sleeve 12 are connected by the same metal rod 15. Due to the use of a vacuum forming mold to conduct heat to the heat dissipation fins, and then spraying water to cool the heat dissipation fins, the heat of the vacuum forming mold is conducted to the heat dissipation fins, increasing the heat dissipation area. The spray nozzles spray water to cool the heat dissipation fins, and then the water is filtered by the filter plate for reuse. The position of the filter plate can also be restricted by the cooperation of the metal rod, sleeve, sleeve and magnet. The restriction can be released by pulling out the metal rod, which makes it easy to clean the filter plate. This effectively solves the problem mentioned in the background technology that the air blowing range of the four air outlets is limited, and some areas of the mold may not be cooled sufficiently, resulting in inconsistent temperatures. It also requires the staff to adjust the position of the four air outlets multiple times during the cooling process to achieve comprehensive cooling of the mold. This achieves uniform, comprehensive and efficient mold cooling, reduces manual operation, simplifies the operation process, and saves time and labor costs.

[0025] In this embodiment, four support rods 16 are fixedly connected to the bottom of the funnel 7, and the bottom of the four support rods 16 is fixedly connected to the same base 17.

[0026] In this embodiment, a temperature sensor 18 is provided at the bottom of the vacuum forming machine mold 3 to detect the temperature of the vacuum forming machine mold 3.

[0027] In this embodiment, the temperature sensor 18 is electrically connected to the temperature controller 19 via a wire, and the temperature controller 19 is fixedly connected to the top of the base 17.

[0028] In this embodiment, a water pump 20 and a PLC programmable controller 21 are fixedly connected to the top of the base 17. The PLC programmable controller 21 is electrically connected to the water pump 20 and the temperature controller 19 through wires. The temperature controller 19 processes the data detected by the temperature sensor 18 and feeds it back to the PLC programmable controller 21. The PLC programmable controller 21 then starts the water pump 20 to pump water for cooling.

[0029] In this embodiment, a water tank 22 is fixedly connected to the top of the base 17. The water tank 22 stores water and collects the filtered water for repeated use.

[0030] In this embodiment, a first water pipe 23 is provided inside the water tank 22. The first water pipe 23 is connected to the input end of the water pump 20. A second water pipe 24 is fixedly connected to the output end of the water pump 20. The second water pipe 24 is fixedly connected to the pipe 5.

[0031] Working Principle: During use, after the vacuum forming process is completed and cooling is required, the PLC programmable controller 21 starts the water pump 20. The water pump 20 draws water from the water tank 22 and injects it into pipe 5 through the first water pipe 23, the water pump 20, and the second water pipe 24. Then, it is injected into the nozzle 6 through pipe 5 and sprayed onto the heat dissipation fins 4. The heat on the heat dissipation fins 4 is transferred to the heat dissipation fins 4, increasing the heat dissipation area. The water sprayed onto the heat dissipation fins 4 cools down more quickly. The water then returns to the water tank 22 through the funnel 7, square pipe 8, and filter plate 10 due to gravity, and is collected. The water in the water tank 22 is kept clean by the filter plate 10. The temperature sensor 18 detects the temperature of the vacuum forming mold 3 and feeds the data back to the temperature controller 19. After the controller 19 processes the data, it feeds it back to the PLC programmable controller 21. The PLC programmable controller 21 controls the start and stop of the water pump 20. When the filter plate 10 needs to be cleaned to ensure filtration efficiency, the metal rod 15 is removed from the sleeve 13 and the sleeve plate 12 to release the restriction. The filter plate 10 can then be removed from the positioning rod 11 for cleaning. During assembly, the filter plate 10 is placed on the positioning rod 11 for positioning, so that the sleeve plate 12 and the sleeve 13 are coaxial. At this time, the metal rod 15 can be inserted into the sleeve plate 12 and the sleeve 13. The magnet 14 attracts the metal rod 15, so that the metal rod 15 can be stably placed in the sleeve plate 12 and the sleeve 13, ensuring the stability of the filter plate 10. The filter plate 10 can also seal the rubber gasket 9, preventing impurities from falling into the water tank 22.
