[0051] This utility model provides a mold temperature control system. Figure 1This is a schematic diagram of a mold temperature control system according to an embodiment of the present invention. Figure 2 This is a partial structural schematic diagram of a mold temperature control system according to an embodiment of the present utility model, with reference to... Figure 1 and Figure 2 The mold temperature control system includes:

[0052] At least one set of electronic flow meter module 1, mold temperature controller 2, and control module;

[0053] The mold temperature controller 2 includes at least one flow meter connection part. Each flow meter connection part includes a first liquid supply end a1 and a first liquid return end a2. The electronic flow meter module 1 is correspondingly connected to the flow meter connection part. The inlet of the electronic flow meter module 1 is connected to the first liquid supply end a1 of the flow meter connection part, and the outlet of the electronic flow meter module 1 is connected to the first liquid return end a2 of the flow meter connection part. The first water inlet of the mold temperature controller 2 is connected to the workshop water inlet pipe b1, and the first water outlet of the mold temperature controller 2 is connected to the workshop water outlet pipe b2. The mold temperature controller 2 is used to output coolant to the electronic flow meter module 1.

[0054] Each electronic flow meter module 1 includes an electro-proportional ball valve assembly 11, a flow meter assembly 12, and a temperature sensor assembly 13. The electro-proportional ball valve assembly 11, the flow meter assembly 12, and the temperature sensor assembly 13 are located on the side of the mold 3 near the flow meter connection part of the mold temperature controller 2.

[0055] The electro-proportional ball valve assembly 11, the flow meter assembly 12, the temperature sensor assembly 13, and the mold temperature controller 2 are electrically connected to the control module. The control module is used to receive the temperature detection signal of the coolant detected in real time by the temperature sensor assembly 13 and send the mold temperature controller control signal to the mold temperature controller 2; at the same time, it receives the flow detection signal of the coolant detected in real time by the flow meter assembly 12 and sends the valve opening control signal to the electro-proportional ball valve assembly 11.

[0056] At least one can be understood as one or more. For example, the mold temperature controller 2 includes one or more flow meter connection parts. Multiple sets of electronic flow meter modules 1 can be set according to the number of molds 3 used, and the number of molds 3 is the same as the number of electronic flow meter modules 1. The electro-proportional ball valve group 11 contains multiple electro-proportional ball valves, the flow meter group 12 contains multiple flow meters, and the temperature sensor group 13 contains multiple temperature sensors. The multiple electro-proportional ball valves, multiple flow meters, and multiple temperature sensors are set one-to-one. A first filter m11 and a first ball valve m21 are provided at the first water inlet of the mold temperature controller 2. A ball valve m2 is provided at the first water outlet of the mold temperature controller 2. A second filter m12 and a second ball valve m22 are provided at the first liquid supply end a1 of the mold temperature controller 2. The electronic flow meter module 1 is set inside the protective cover l1, and an electrical quick connector l2 is provided on the protective cover 11 to connect to the control module.

[0057] Specifically, temperature sensor group 13 detects the temperature signal of the coolant flowing into electronic flow meter module 1 in real time and transmits the detected coolant temperature signal to the control module. Flow meter group 12 detects the flow rate of the coolant flowing into electronic flow meter module 1 in real time and transmits the detected flow rate signal to the control module. After receiving the coolant temperature signal detected by temperature sensor group 13, the control module compares the received coolant temperature signal with a temperature threshold signal set in the control module, and sends a mold temperature controller control signal to mold temperature controller 2 according to the comparison result to control the working state of mold temperature controller 2. For example, if the received coolant temperature signal is less than the temperature threshold signal, the output power of mold temperature controller 2 is increased to increase the temperature of the coolant flowing into electronic flow meter module 1; if the received coolant temperature signal is greater than or equal to the temperature threshold signal, the output power of mold temperature controller 2 is decreased to decrease the temperature of the coolant flowing into electronic flow meter module 1. The control module also compares the received coolant flow detection signal, which is detected in real time by the flow meter group 12, with a flow threshold signal set within the control module. Based on the comparison result, it sends a valve opening control signal to the electro-proportional ball valve group 11 to control the valve opening of the electro-proportional ball valve group 11. For example, if the received coolant flow detection signal is less than the flow threshold signal, the control module increases the valve opening of the electro-proportional ball valve group 11 to increase the flow rate of coolant flowing into the electronic flow meter module 1; if the received coolant flow detection signal is greater than or equal to the flow threshold signal, the control module decreases the valve opening of the electro-proportional ball valve group 11 to decrease the flow rate of coolant flowing into the electronic flow meter module 1.

[0058] The mold temperature control system provided in this embodiment of the utility model receives the temperature detection signal of the coolant detected in real time by the temperature sensor group 13 through the control module, and sends the mold temperature controller control signal to the mold temperature controller 2; at the same time, it receives the flow detection signal of the coolant detected in real time by the flow meter group 12, and sends the valve opening control signal to the electro-proportional ball valve group 11, so as to stabilize the mold 3 within the preset temperature range, realize the closed-loop control of coolant temperature and coolant flow, and improve production efficiency.

[0059] Further reference Figure 1 The electronic flow meter module also includes: a liquid separator 14 and a liquid combiner 15;

[0060] The first end of the liquid separator 14 is connected to the first liquid supply end a1 of the flow meter connection part, the second end of the liquid separator 14 is connected to the second end of the liquid combiner 15 through the first branch pipe c1, the third end of the liquid separator 14 is connected to the third end of the liquid combiner 15 through the second branch pipe c2, and the first end of the liquid combiner 15 is connected to the first liquid return end a2 of the flow meter connection part.

[0061] The electro-proportional ball valve assembly 11 includes a first electro-proportional ball valve 111 and a second electro-proportional ball valve 112; the flow meter assembly 12 includes a first flow meter 121 and a second flow meter 122; and the temperature sensor assembly 13 includes a first temperature sensor 131 and a second temperature sensor 132.

[0062] The first electro-proportional ball valve 111, the first flow meter 121 and the first temperature sensor 131 are installed in the first branch pipe c1, and the second electro-proportional ball valve 112, the second flow meter 122 and the second temperature sensor 132 are installed in the second branch pipe c2. The first branch pipe c1 and the second branch pipe c2 are located close to the mold 3.

[0063] The control module is used to receive the first temperature signal of the coolant detected in real time by the first temperature sensor 131 and the second temperature signal of the coolant detected in real time by the second temperature sensor 132, and send the mold temperature controller control signal to the mold temperature controller 2; at the same time, it receives the first flow signal of the coolant detected in real time by the first flow meter 121, sends the first valve opening signal to the first electro-proportional ball valve 111; and receives the second flow signal of the coolant detected in real time by the second flow meter 122, sends the second valve opening signal to the second electro-proportional ball valve 112.

[0064] Specifically, the first temperature sensor 131 detects the first temperature value of the coolant flowing into the first branch pipe c1 of the electronic flow meter module 1 in real time, and converts the detected first temperature value of the coolant into a first temperature signal and transmits it to the control module. The second temperature sensor 132 detects the second temperature value of the coolant flowing into the second branch pipe c2 of the electronic flow meter module 1 in real time, and converts the detected second temperature value of the coolant into a second temperature signal and transmits it to the control module. The first flow meter 121 detects the first flow rate value of the coolant flowing into the first branch pipe c1 of the electronic flow meter module 1 in real time, and converts the detected first flow rate value into a first flow signal and transmits it to the control module. The second flow meter 122 detects the second flow rate value of the coolant flowing into the second branch pipe c2 of the electronic flow meter module 1 in real time, and converts the detected second flow rate value into a second flow signal and transmits it to the control module.

[0065] After receiving the first temperature signal of the coolant detected in real time by the first temperature sensor 131 and the second temperature signal of the coolant detected in real time by the second temperature sensor 131, the control module compares the received first and second temperature signals of the coolant with the temperature threshold signals set in the control module, and sends a mold temperature controller control signal to the mold temperature controller 2 according to the comparison results to control the working state of the mold temperature controller 2. The control module also compares the received first flow rate signal of the coolant detected in real time by the first flow meter 121 with the flow threshold signal set in the control module, and controls the valve opening of the first electro-proportional ball valve group 111 according to the comparison results; and compares the received second flow rate signal of the coolant detected in real time by the second flow meter 122 with the flow threshold signal set in the control module, and controls the valve opening of the second electro-proportional ball valve group 112 according to the comparison results.

[0066] Further reference Figure 1 The electronic flow meter module also includes:

[0067] Third temperature sensor 133 and fourth temperature sensor 134;

[0068] The third temperature sensor 133 is installed in the first branch pipe c1 and is located on the side of the mold 3 near the liquid block 15. The fourth temperature sensor 134 is installed in the second branch pipe c2 and is located on the side of the mold 3 near the liquid block 15.

[0069] The third temperature sensor 133 and the fourth temperature sensor 134 are electrically connected to the control module. The third temperature sensor 133 is used to acquire the third temperature value of the coolant flowing through the mold 3 in real time and convert the third temperature value into a third temperature signal and transmit it to the control module. The fourth temperature sensor 134 is used to acquire the fourth temperature value of the coolant flowing through the mold 3 in real time and convert the fourth temperature value into a fourth temperature signal and transmit it to the control module.

[0070] The control module is used to receive the first temperature signal and the third temperature signal, and send the third valve opening signal to the first electro-proportional ball valve 111. At the same time, it receives the second temperature signal and the fourth temperature signal and sends the fourth valve opening signal to the second electro-proportional ball valve 112.

[0071] Specifically, after receiving the first temperature signal and the third temperature signal, the control module subtracts the first temperature signal from the third temperature signal to determine the first temperature difference signal. It then compares the first temperature difference signal with a preset first temperature difference signal and sends a third valve opening signal to the first electro-proportional ball valve 111 based on the comparison result. This controls the valve opening of the first electro-proportional ball valve 111. For example, if the first temperature difference signal is greater than or equal to the preset first temperature difference signal, it indicates that the coolant has consumed most of its heat after flowing through the mold 3. In this case, the valve opening of the first electro-proportional ball valve 111 needs to be increased to increase the flow rate of coolant into the first branch pipe c1, thereby preventing a large temperature difference after the coolant flows through the mold 3 and improving the cooling effect on the mold 3. If the first temperature difference signal is less than the preset first temperature difference signal, it indicates that the coolant has consumed less heat after flowing through the mold 3. In this case, it is not necessary to increase the valve opening of the first electro-proportional ball valve 111 to avoid a large temperature difference after the coolant flows through the mold 3, while still satisfying the cooling effect on the mold 3.

[0072] After receiving the second and fourth temperature signals, the control module calculates the difference between them to determine the second temperature difference signal. It then compares this second temperature difference signal with a preset first temperature difference signal and sends a fourth valve opening signal to the second electro-proportional ball valve 112 based on the comparison result. This controls the valve opening of the second electro-proportional ball valve 112. For example, if the second temperature difference signal is greater than or equal to the first preset temperature difference signal, it indicates that the coolant has consumed most of its heat after flowing through the mold 3. In this case, the valve opening of the second electro-proportional ball valve 112 needs to be increased to increase the flow rate of coolant into the second branch pipe c2, thereby preventing a large temperature difference after the coolant flows through the mold 3 and improving the cooling effect on the mold 3. If the second temperature difference signal is less than the first preset temperature difference signal, it indicates that the coolant has consumed less heat after flowing through the mold 3. In this case, it is not necessary to increase the valve opening of the second electro-proportional ball valve 112 to avoid a large temperature difference after the coolant flows through the mold 3, while still satisfying the cooling effect on the mold 3.

[0073] Further reference Figure 1 The electronic flow meter module also includes:

[0074] First pressure sensor 161, second pressure sensor 162, third pressure sensor 163 and fourth pressure sensor 164;

[0075] The first pressure sensor 161 is installed in the first branch pipe c1 and is located on the side of the mold 3 near the liquid distribution block 14; the second pressure sensor 162 is installed in the second branch pipe c2 and is located on the side of the mold 3 near the liquid distribution block 14; the third pressure sensor 163 is installed in the first branch pipe c1 and is located on the side of the mold 3 near the liquid combination block 15; and the fourth pressure sensor 164 is installed in the second branch pipe c2 and is located on the side of the mold 3 near the liquid combination block 15.

[0076] The first pressure sensor 161, the second pressure sensor 162, the third pressure sensor 163, and the fourth pressure sensor 164 are electrically connected to the control module. The first pressure sensor 161 is used to acquire the first pressure value of the coolant flowing into the first branch pipe c1 in real time, and convert the first pressure value into a first pressure signal and transmit it to the control module. The second pressure sensor 162 is used to acquire the second pressure value of the coolant flowing into the second branch pipe c2 in real time, and convert the second pressure value into a second pressure signal and transmit it to the control module. The third pressure sensor 163 is used to acquire the third pressure value of the coolant flowing out of the first branch pipe c1 in real time, and convert the third pressure value into a third pressure signal and transmit it to the control module. The fourth pressure sensor 164 is used to acquire the fourth pressure value of the coolant flowing out of the second branch pipe c2 in real time, and convert the fourth pressure value into a fourth pressure signal and transmit it to the control module.

[0077] The control module is used to receive the first pressure signal and the third pressure signal, send the fifth valve opening signal to the first electro-proportional ball valve 111, and simultaneously receive the second pressure signal and the fourth pressure signal, and send the sixth valve opening signal to the second electro-proportional ball valve 112.

[0078] Specifically, after receiving the first and third pressure signals, the control module subtracts the first and third pressure signals to determine the first pressure difference signal. It then compares this first pressure difference signal with a preset first pressure difference signal and, based on the comparison result, sends a fifth valve opening signal to the first electro-proportional ball valve 111 to control its valve opening. Similarly, after receiving the second and fourth pressure signals, the control module subtracts the second and fourth pressure signals to determine the second pressure difference signal. It then compares this second pressure difference signal with the preset first pressure difference signal and, based on the comparison result, sends a sixth valve opening signal to the second electro-proportional ball valve 112 to control its valve opening.

[0080] The control module is used for:

[0081] Send an alarm signal to the alarm module to control the alarm module to handle the alarm.

[0082] Specifically, if the first pressure difference signal is greater than or equal to the second preset pressure difference signal and lasts for a first preset duration, it indicates that after controlling the valve opening of the first electro-proportional ball valve 111 to increase the valve opening for a first preset duration, it is still impossible to increase the flow rate of the coolant flowing through the mold 3. At this time, the blockage inside some of the first branch pipes c1 around the mold 3 is relatively serious, which has affected the cooling effect on the mold 3. At this time, the control alarm module will perform an alarm to remind the staff that the blockage inside the first branch pipe c1 is relatively serious and needs to be dealt with in time. If the second pressure difference signal is greater than or equal to the second preset pressure difference signal and lasts for a first preset duration, it indicates that after controlling the valve opening of the second electro-proportional ball valve 112 to increase the valve opening for a first preset duration, it is still impossible to increase the flow rate of the coolant flowing through the mold 3. At this time, the blockage inside some of the second branch pipes c2 around the mold 3 is relatively serious, which has affected the cooling effect on the mold 3. At this time, the control alarm module will perform an alarm to remind the staff that the blockage inside the second branch pipe c2 is relatively serious and needs to be dealt with in time. The second preset pressure difference signal is greater than the first preset pressure difference signal.

[0085] The first filter m11 is installed at the first water inlet of the mold temperature controller 2, and the second filter m12 is installed at the first liquid supply end a1 of the mold temperature controller 2.

[0086] Specifically, the first filter m11 is used to filter impurities in the coolant flowing in from the first water inlet of the mold temperature controller 2.
