Description

Technical Field

[0001] This application relates to the field of injection molding technology, specifically to a plastic housing cooling device. Background Technology

[0002] Injection molding is a highly efficient molding method widely used in industrial product manufacturing. Its core process is as follows: after heating plastic granules to a molten state, they are precisely injected into a pre-designed mold cavity through a high-pressure injection system. Then, the heat is quickly removed by a cooling medium inside the mold, causing the molten plastic to solidify and form a shape. After the product has completely cooled, it is demolded through an ejection mechanism, ultimately obtaining a plastic product with accurate dimensions and excellent surface quality.

[0003] In existing technologies, traditional cooling methods mostly use a single mode of water cooling or air cooling. A single cooling medium is not enough to quickly remove the heat inside the mold, resulting in a long cooling time for the workpiece and reduced production efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a plastic shell cooling device that integrates water cooling and air cooling structures, achieving dual-mode synergistic cooling and significantly improving cooling efficiency. This solves the problem that a single cooling medium cannot quickly remove heat from the mold, resulting in a long cooling time for the workpiece and reduced production efficiency.

[0005] To achieve the above objectives, this application provides the following technical solution: a plastic shell cooling device, comprising a mold, a mold base fixedly connected inside the mold, a cavity opened inside the mold base, a first cooling pipe arranged at equal intervals fixedly connected inside the mold, two water tanks provided below the mold, the two ends of the first cooling pipes respectively communicating with the two water tanks, an inlet pipe communicating with the inside of one of the water tanks, and an outlet pipe communicating with the inside of the other water tank, and a second cooling pipe fixedly connected inside the mold, the two ends of the second cooling pipe respectively communicating with the two water tanks.

[0006] The mold has a first heat dissipation fin that is equidistantly arranged inside, a second heat dissipation fin that is equidistantly arranged inside, an air duct that is equidistantly arranged on the outer surface of the mold, an exhaust channel that is equidistantly arranged at the top of the air duct, an exhaust fan that is equidistantly arranged inside the exhaust channel, an air inlet channel that is equidistantly arranged at the bottom of the air duct, a temperature sensor that is equidistant from the inside of the mold, a controller that is equidistantly mounted on the upper surface of the air duct, and a touch screen that is mounted on the outer surface of the air duct.

[0007] The above solution addresses the issue that a single cooling medium is insufficient to quickly remove heat from the mold, resulting in prolonged workpiece cooling time and reduced production efficiency. By incorporating a first cooling pipe, a second cooling pipe, a water tank, an inlet pipe, and an outlet pipe, uniform water cooling of the mold and mold base can be achieved. Furthermore, by installing air ducts, first heat dissipation fins, second heat dissipation fins, an exhaust channel, an exhaust fan, and an inlet channel, uniform air cooling of the mold and mold base can be achieved. Simultaneous water cooling and air cooling enable dual-mode synergistic cooling, significantly shortening workpiece cooling time and improving cooling efficiency.

[0008] Furthermore, the first cooling pipe is arranged around the side wall of the mold base, and the first cooling pipe is adapted to the contour of the side wall of the mold base and is arranged close to the side wall of the mold base.

[0009] With the above solution, the first cooling pipe is set close to the mold base sidewall and adapted to the contour of the mold base sidewall, which can optimize the cooling path, efficiently remove the heat from the sidewall area during injection molding, and significantly improve cooling and production efficiency.

[0010] Furthermore, the second cooling pipe is distributed in a serpentine pattern on the bottom wall of the mold base, and the second cooling pipe is located close to the bottom wall of the mold base.

[0011] The above solution increases the heat dissipation area of ​​the bottom wall region of the mold base by the serpentine distribution of the second cooling pipe, while also ensuring the uniformity of heat dissipation in the bottom wall region of the mold base and optimizing the heat dissipation effect.

[0012] Furthermore, the side of each first heat dissipation fin closest to the mold base is in contact with the side wall of the mold base, and the side of each second heat dissipation fin closest to the mold base is in contact with the bottom wall of the mold base.

[0013] Through the above scheme, the first heat dissipation fin can ensure the heat dissipation needs of the side wall area of ​​the mold base, and the second heat dissipation fin can ensure the heat dissipation needs of the bottom wall area of ​​the mold base, thereby ensuring the heat dissipation uniformity of the workpiece inside the mold base and optimizing the air cooling effect.

[0014] Furthermore, the exhaust duct and the intake duct are arranged diagonally, and both the first and second heat dissipation fins are located inside the air duct.

[0015] The above scheme, with its diagonally arranged air intake and exhaust channels, ensures that the airflow path completely covers the air duct, preventing dead corners inside the air duct and affecting the air-cooling effect.

[0016] Furthermore, both the first and second cooling pipes are made of copper alloy, and both the first and second heat dissipation fins are made of aluminum alloy.

[0017] The above solutions demonstrate that both copper alloy and aluminum alloy materials have high thermal conductivity, which can optimize the heat dissipation effects of water cooling and air cooling.

[0018] Furthermore, both the inlet and outlet pipes have threaded structures on their outer circumferential surfaces, and limit rings are fixedly fitted onto the outer circumferential surfaces of both the inlet and outlet pipes.

[0019] The above solution allows for quick connection to external cooling equipment via the threaded structure on the inlet and outlet pipes. The limiting rings can provide a certain degree of restriction when the inlet and outlet pipes are connected to the external cooling equipment, facilitating the installation and disassembly of the external cooling equipment.

[0020] Furthermore, baffles are provided at the top of the exhaust duct and the bottom of the air inlet duct, and the baffles have equidistant ventilation holes inside.

[0021] Through the above solution, the baffle and ventilation holes can play a role in dust prevention, blocking dust and foreign objects from entering the air duct, avoiding the decrease in heat dissipation efficiency caused by dust accumulation on the heat dissipation fins, and also play a certain protective role, preventing accidental contact with the high-speed rotating exhaust fan and improving the safety of equipment use.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects: This plastic housing cooling device, by setting up a first cooling pipe, a second cooling pipe, a water tank, an inlet pipe, and an outlet pipe, can achieve water cooling of the mold and mold base and ensure uniform heat dissipation. By setting up an air duct, a first heat dissipation fin, a second heat dissipation fin, an exhaust duct, an exhaust fan, and an inlet duct, it can achieve air cooling of the mold and mold base and ensure uniform heat dissipation. The simultaneous water cooling and air cooling achieve dual-mode synergistic cooling, significantly shortening the cooling time of the workpiece and improving cooling efficiency.

[0028] Please see Figure 4 , Figure 5 and Figure 6The first cooling pipe 4 is arranged around the side wall of the mold base 2. The first cooling pipe 4 is adapted to the contour of the side wall of the mold base 2 and is arranged close to the side wall of the mold base 2. The first cooling pipe 4 is arranged close to the side wall of the mold base 2 and is adapted to the contour of the side wall of the mold base 2. This can optimize the cooling path, efficiently remove the heat from the side wall area during the injection molding process, and significantly improve cooling and production efficiency.

[0029] Please see Figure 4 and Figure 6 The second cooling pipe 8 is distributed in a serpentine pattern on the bottom wall of the mold base 2. The second cooling pipe 8 is set close to the bottom wall of the mold base 2. The serpentine distribution of the second cooling pipe 8 increases the heat dissipation area of ​​the bottom wall area of ​​the mold base 2, while also ensuring the heat dissipation uniformity of the bottom wall area of ​​the mold base 2 and optimizing the heat dissipation effect.

[0030] Please see Figure 3 , Figure 4 and Figure 5 Each first heat dissipation fin 9 is in contact with the side wall of the mold base 2 on the side closest to the mold base 2, and each second heat dissipation fin 10 is in contact with the bottom wall of the mold base 2 on the side closest to the mold base 2. The first heat dissipation fin 9 can ensure the heat dissipation requirements of the side wall area of ​​the mold base 2, and the second heat dissipation fin 10 can ensure the heat dissipation requirements of the bottom wall area of ​​the mold base 2, thereby ensuring the heat dissipation uniformity of the workpiece in the mold base 2 and optimizing the air cooling effect.

[0031] Please see Figure 1 , Figure 2 and Figure 3 The exhaust duct 12 and the air inlet duct 14 are arranged diagonally. The first heat dissipation fin 9 and the second heat dissipation fin 10 are both located inside the air duct 11. The diagonally arranged air inlet duct 14 and exhaust duct 12 can completely cover the air duct 11, avoiding dead corners inside the air duct 11 and affecting the air cooling effect.

[0032] Please see Figure 4 , Figure 5 and Figure 6 The first cooling pipe 4 and the second cooling pipe 8 are both made of copper alloy, and the first heat dissipation fin 9 and the second heat dissipation fin 10 are both made of aluminum alloy.

[0033] Please see Figure 4 , Figure 5 and Figure 6Both the inlet pipe 6 and the outlet pipe 7 have threaded structures on their outer circumferences. Limiting rings 18 are fixedly sleeved on the outer circumferences of both the inlet pipe 6 and the outlet pipe 7. They can be quickly connected to external cooling equipment through the threaded structures on the inlet pipe 6 and the outlet pipe 7. The limiting rings 18 can play a certain limiting role when the inlet pipe 6 and the outlet pipe 7 are connected to the external cooling equipment, which facilitates the installation and disassembly of the external cooling equipment.

[0034] Please see Figure 1 , Figure 2 and Figure 3 Both the top of the exhaust duct 12 and the bottom of the air inlet duct 14 are equipped with baffles 19. The baffles 19 have equidistantly arranged ventilation holes. The baffles 19 and the ventilation holes can prevent dust and foreign objects from entering the air duct 11, thus avoiding the decrease in heat dissipation efficiency caused by dust accumulation on the heat dissipation fins. At the same time, they can also play a certain protective role, preventing accidental contact with the high-speed rotating exhaust fan 13 and improving the safety of equipment use.

[0035] In this embodiment, a plastic shell cooling device, by setting a first cooling pipe 4, a second cooling pipe 8, a water tank 5, a water inlet pipe 6, and a water outlet pipe 7, can achieve water cooling heat dissipation for mold 1 and mold base 2 and ensure the uniformity of heat dissipation. By setting an air duct 11, a first heat dissipation fin 9, a second heat dissipation fin 10, an exhaust air duct 12, an exhaust fan 13, and an air inlet air duct 14, it can achieve air cooling heat dissipation for mold 1 and mold base 2 and ensure the uniformity of heat dissipation. The simultaneous water cooling and air cooling achieve dual-mode synergistic cooling, significantly shortening the cooling time of the workpiece and improving cooling efficiency.

[0036] It should be noted that the mold 1 has an injection pipe that is connected to the cavity 3. The mold 1 needs to be used in conjunction with an external mold. The external mold needs to be inserted into the cavity 3 and closed with the mold 1. Then, the subsequent injection operation can be carried out through the injection pipe. The water inlet pipe 6 and the water outlet pipe 7 both pass through the air duct 11.

[0037] The working principle of the above embodiments is as follows: The inlet pipe 6 and outlet pipe 7 can be connected to external cooling equipment. When cooling of the workpiece is required, the external cooling equipment is activated. The coolant enters the water tank 5 through the inlet pipe 6, and is then distributed to the first cooling pipe 4 and the second cooling pipe 8. The high thermal conductivity of the copper alloy material quickly absorbs the heat from the mold 1 and mold base 2. The coolant then flows into another water tank 5 and is discharged through the outlet pipe 7, forming a closed-loop circulation to achieve uniform water cooling of the injection-molded workpiece inside the mold base 2. At the same time, the exhaust fan 13 is activated, which drives the airflow in the air duct 11. The air flows into the air duct 11 through the air inlet channel 14 and is finally discharged from the exhaust channel 12 at the opposite corner. The heat from the injection-molded workpiece is dissipated through the mold base 2 and the mold 1. The heat is transferred to the first heat dissipation fin 9 and the second heat dissipation fin 10. During the air flow, the heat on the first heat dissipation fin 9 and the second heat dissipation fin 10 will be discharged from the exhaust channel 12, completing the uniform air cooling of the injection molded workpiece inside the mold base 2. During the heat dissipation operation, the temperature sensor 15 can collect the temperature data of the mold 1 in real time and transmit it to the controller 16. The controller 16 will automatically control the speed of the exhaust fan 13, the flow rate of the coolant, or switch the cooling mode according to the preset temperature threshold to ensure the cooling effect of the equipment and improve the cooling efficiency. The operator can set the target temperature, view real-time data, or manually adjust the parameters through the touch screen 17 to achieve a balance between equipment intelligence and ease of operation.
