[0017] The present invention will now be described in further detail with reference to the accompanying drawings.
[0018] Combined with appendix Figs. 1-3 A cooling device for metal and plastic molding includes a cooling cabinet body 1, a cooling cavity 2 connected inside the cooling cabinet body 1, a water inlet pipe 4 connected to one side of the cooling cabinet body 1, the water inlet pipe 4 is generally connected to the water outlet pipe of the mold cooling cavity, a first flow control valve 12 is connected to the water inlet pipe 4, and multiple interconnected coil structures 5 are provided in the water inlet pipe 4 extending into the cooling cavity 2, and heat exchange pipes 6 are wrapped around the outside of the coil structures 5.
[0019] The heat exchange pipe 6 is provided with an air inlet pipe 8 and an air outlet pipe 9 at both ends. The air inlet pipe 8 requires an external cold air delivery device, which is a common existing technology and will not be described in detail. If the temperature of the coolant does not need to be too low, only an air pump is needed. If the temperature requirement of the coolant is higher, a corresponding cold air delivery device can be installed. The air inlet pipe 8 and the air outlet pipe 9 are respectively connected to a second flow control valve 10 and a one-way valve 11. A first temperature sensor 7 is connected between multiple coil structures 5. A second temperature sensor 14 is connected to the water outlet pipe 13. That is, the temperature between multiple coil structures 5 can be sensed by the first temperature sensor 7, so the flow of the first flow control valve 12 and the second flow control valve 10 can be adjusted accordingly to ensure that the temperature of the second temperature sensor 14 meets the standard.
[0020] The last coil structure 5 is connected to a water outlet pipe 13 extending to the outside at its rear end. A circulation pump 15 is connected to the end of the water outlet pipe 13. The circulation pump 15 is connected to a circulation pipe 16, which is directly connected to the mold cooling cavity.
[0021] The inner side of the cold cavity 2 is provided with a heat insulation cotton layer 3. The front side of the cooling cabinet body 1 is provided with a sealed maintenance door 20. The rear side of the cooling cabinet body 1 is connected to a compressor refrigeration unit 17. The compressor refrigeration unit 17 is connected to a refrigeration plate 18 extending into the cold cavity 2. The cold cavity 2 is provided with a third temperature sensor 19. The compressor refrigeration unit 17 is set to maintain a low temperature inside the cold cavity 2, which can ensure the cooling operation when the coolant is transported in the cold cavity 2. Maintaining a low temperature results in relatively low energy consumption. That is, the cooling device of this application does not need to set up an evaporator or other equipment, thus ensuring that the energy consumption is not too high. Long-term operation can significantly reduce energy consumption. Moreover, the coolant does not come into contact with the outside, which can reduce pollution and waste. The cooling cabinet body 1 and multiple coil structures 5 shown in the figure of this application are arranged horizontally, which reduces the vertical area. In actual production, multiple coil structures 5 can also be arranged side by side. The specific structure can be designed according to the site area requirements.
[0022] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
