[0032] Below, in conjunction with the accompanying drawings and specific implementation methods, the utility model is further described:

[0033] like Figure 1 , 2 As shown, a mold cooling machine with intermittent cooling function includes a mold 1, a water pump 2, a cooling water tank 3 and a heat exchanger 4, wherein the cooling water tank 3 is connected to the heat exchanger 4 through a cooling water outlet pipe 10, the heat exchanger 4 is connected to the mold 1 through a cooling water inlet pipe 20, the mold 1 is connected to the cooling water tank 3 through a cooling water return pipe 30, and the cooling water outlet pipe is provided with a water pump 2;

[0034] The mold 1 is provided with a plurality of flow channels, and the water inlets and water outlets of the plurality of flow channels are provided with a water inlet branch pipe 40 and a water outlet branch pipe 50 respectively;

[0035] A flow switch 51 module 5 is provided between the mold 1 and the heat exchanger 4. The flow switch 51 module 5 includes a plurality of flow switches 51 connected in parallel. The water inlets of the plurality of flow switches 51 are connected to the cooling water inlet pipe 20, and the water outlets are respectively connected to the water branch pipe 40. The cooling water return pipe 30 is connected to the water outlet branch pipe 50 at one end close to the mold 1.

[0036] A controller 6 is also included, and the plurality of flow switches 51 are electrically connected to the controller 6 .

[0037] In this embodiment, multiple flow switches 51 adopt an integrated structure design with high integration and small size, and can be easily and flexibly plugged in and installed, thereby improving assembly and disassembly efficiency and connection reliability.

[0038] In this embodiment, a flow switch 51 is provided on each water inlet branch pipe 40 connected to the flow channel of the mold 1, and the on-off or opening size of each flow switch 51 is controlled by the controller 6 to control the on-off or flow size of the cooling water; the on-off time or opening size adjustment time of each flow switch 51 is set according to the actual needs of the product;

[0039] This enables precise control of cooling water in each flow channel of the mold 1, effectively maintains the thermal balance of the temperature of the mold 1, and improves the stability of product quality.

[0040] Further, such as Figure 1 , 2As shown, a first temperature sensor 1a is respectively provided on the plurality of water outlet branch pipes 50;

[0041] The first temperature sensor 1 a is electrically connected to the controller 6 .

[0042] In this embodiment, the first temperature sensor 1a is used to detect the cooling water temperature value of the corresponding water outlet branch pipe 50. When the first temperature sensor 1a monitors that the temperature value is greater than or less than the set range value, the controller 6 controls the opening size of the flow switch 51 to increase or decrease the flow rate of the cooling water; thereby, the flow rate of the corresponding cooling water can be automatically adjusted and controlled according to the temperature range value set for each flow channel, effectively maintaining the thermal balance of the mold 1 temperature and ensuring the normal operation of the mold 1.

[0043] Further, such as Figure 1 , 2 As shown, the cooling water inlet pipe 20 is provided with an electronic flow meter 60 and a second temperature sensor 2a at one end close to the heat exchanger 4, the cooling water return pipe 30 is provided with a third temperature sensor 3a, and the cooling water outlet pipe 10 is provided with a fourth temperature sensor 4a;

[0044] The electronic flow meter 60 , the second temperature sensor 2 a , the third temperature sensor 3 a , and the fourth temperature sensor 4 a are electrically connected to the controller 6 .

[0045] In this embodiment, the second temperature sensor 2a is used to monitor in real time the temperature value of the cooling water flowing into the mold 1 each time the mold 1 is processed; the third temperature sensor 3a is used to monitor in real time the temperature value of the cooling water flowing out of the mold 1 each time the mold 1 is processed; the fourth temperature sensor 4a is used to monitor in real time the temperature value of the cooling water flowing from the cooling water tank 3 to the heat exchanger 4 each time the mold 1 is processed; the electronic flow meter 60 is used to monitor in real time the flow value of the cooling water each time the mold 1 is processed; and real-time online monitoring of the temperature value of the cooling water at different positions and the flow value of the cooling water each time the mold 1 is processed is realized.

[0046] Further, such as Figure 2 As shown, the controller 6 includes a visual touch module 61 and a data storage module 62 electrically connected to the controller 6 .

[0047] In this embodiment, an electronic flow meter 60 and a second temperature sensor 2a are arranged on the cooling water inlet pipe 20, a third temperature sensor 3a is arranged on the cooling water return pipe 30, and a fourth temperature sensor 4a is arranged on the cooling water outlet pipe 10, so as to respectively detect the flow value of the cooling water and the temperature value of the cooling water at the corresponding position during each processing of the mold 1 in real time, and then transmit the corresponding flow value and temperature value to the data storage module 62 in the form of electrical signals for recording and preservation; at the same time, the flow value and temperature value stored in the data storage module 62 can be called by the visual touch module and displayed on the display screen, so as to realize the real-time recording, preservation and calling of each mold data (flow rate, temperature).

[0048] Furthermore, the flow switch 51 is a solenoid valve.

[0049] In this embodiment, the solenoid valve is an electrically controlled proportional valve, which has high control accuracy and stable and reliable operation.

[0050] Further, such as Figure 1 As shown, it also includes a chilled water circulation system 7 connected to the heat exchanger 4.

[0051] In this embodiment, the cold source of the chilled water circulation system 7 is the large circulating cooling water of the factory, and no additional refrigeration device is required, which effectively saves energy consumption.

[0052] Further, such as Figure 1 As shown, the cooling water outlet pipe 10 is located between the water pump 2 and the heat exchanger 4 and is provided with a filter 8 , and the filter 8 is provided with an automatic exhaust valve 9 .

[0053] In this embodiment, the above structure filters out impurities in the cooling water and discharges gas in the cooling water, thereby ensuring the cleanliness and purity of the cooling water and maximizing the heat exchange effect.

[0054] Further, such as Figure 1 , 2 As shown, the cooling water outlet pipe 10 is located between the filter 8 and the heat exchanger 4 and is provided with a pressure sensor 70 , and the pressure sensor 70 is electrically connected to the controller 6 .

[0055] In this embodiment, when the pressure sensor 70 detects a pressure value that is less than or greater than a set pressure value, it indicates that the filtering performance of the filter 8 is lower than the effective filtering value, and the actual pressure value is converted into an electrical signal and transmitted to the controller 6 for early warning.

[0056] Further, such as Figure 1 , 2 As shown, an upper liquid level sensor 80 and a lower liquid level sensor 90 are provided on the cooling water tank 3 .

[0057] In this embodiment, the above structure can detect in real time whether the water level of the cooling water in the cooling water tank 3 is within the set range, thereby preventing the water level from being too low and affecting the normal operation of the mold cooler.

[0058] Further, such as Figure 1 , 2 As shown, the cooling water tank 3 further includes a water supply pipe 100 and an overflow pipe 110, and the water supply pipe 100 and the overflow pipe 110 are respectively provided with a first valve 120 and a second valve 130;

[0059] The first valve 120 , the second valve 130 , the upper liquid level sensor 80 , and the lower liquid level sensor 90 are electrically connected to the controller 6 .

[0060] In this embodiment, under the action of the controller 6, when the water level of the cooling water is higher than the upper liquid level sensor 80, the upper liquid level sensor 80 is triggered to control the second valve 130 to open; when the water level of the cooling water is lower than the lower liquid level sensor 90, the lower liquid level sensor 90 is triggered to control the first valve 120 to open, and cooling water is supplied to the cooling water tank 3 through the water supply pipe 100; thereby, the cooling water in the cooling water tank 3 is automatically controlled within the set water level range to ensure the normal operation of the mold cooler.

[0061] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the scope of protection of the claims of the utility model patent.
