The branch pipelines 12 have a water inlet section 121 and a water return section 122. The main pipeline 11 is connected to the water inlet section 121 of the branch pipeline 12 through the integrated block 14;

[0026] The system 100 includes a temperature sensor 101, a proportional valve 102, a temperature control module 103, a PLC 104, an industrial wireless router 105, and an industrial control computer 106;

[0028] There are multiple proportional valves 102, and they are respectively installed on the water inlet section 121 of the branch pipeline 12 in one-to-one correspondence;

[0030] In this embodiment, the annular seat foaming line has 42 stations, and both the temperature sensors and the proportional valves are provided with 42; in this embodiment, the temperature sensor is a PT100 thermal resistor, and the PT100 thermal resistor is connected to the temperature feedback point of the temperature control channel of the temperature control module. The model of the PT100 thermal resistor is HL-9104; in this embodiment, the temperature sensor is connected to the temperature control module through a temperature control communication module, and the model of the temperature control communication module is AI-MODBUS-S-D5; in this embodiment, the temperature control module automatically performs PID temperature control according to the deviation between the set value and the feedback value; in this embodiment, the model of the temperature control module is AI-7548D71, and the output of the temperature control channel of the temperature control module is 4-20 mA current, controlling the flow rate of the proportional valve from 0 to 100%; in this embodiment, the model of the proportional valve is TC8800, and the PLC is Siemens S7-1215PN; in this embodiment, the integrated block is made of stainless steel 304 material FF1B; in this embodiment, the model of the industrial control computer is TPRO-15C; in this embodiment, the model of the industrial wireless router is TL-AP1900DG; manual ball valves (not shown in the figure) are added to the main pipelines corresponding to the water inlet and outlet of the mold base to facilitate maintenance.

[0031] It should be noted that the mold temperature controller provides hot water for the main pipeline.

[0032] The working principle of the present utility model: The set temperature is set through the industrial control computer interface and output to the set value of the corresponding channel of the intelligent temperature control module through the PLC; the PT100 thermal resistor at the return water pipe is connected to the temperature feedback point of this temperature control channel. The intelligent temperature control module automatically performs PID temperature control according to the deviation between the set value and the feedback value (PID multi-segment temperature control, and temperature control parameters such as differentiation, integration, and proportional gain can be set through PLC communication). The output of the temperature control channel is 4-20 mA current, controlling the flow rate of the proportional valve. The flow rate corresponding to 4-20 mA is 0-100%; the temperature at each return water pipe can be read into the PLC through the temperature control module, and different segmented temperature controls are performed according to the difference between the current temperature and the set value. For example: when the equipment is just started, the equipment temperature is relatively low, and at this time, it can be set to full power heating, and the proportional valve is fully opened, and the heating effect is equivalent to that before the transformation. When it is detected that the return water temperature is close to the set temperature (such as 10 °C), the PID temperature control mode is started. In the initial stage, a larger P value is used to improve the response speed. When the temperature is within ±1 of the set value, the P value is reduced and the D value is increased to enhance the temperature stability.

[0033] Some of the data in the above formula are calculated by removing the dimension and taking its numerical value. The formula is obtained by software simulation of a large amount of collected data to obtain a formula closest to the actual situation; the preset parameters and preset thresholds in the formula are set by those skilled in the art according to the actual situation or obtained through simulation of a large amount of data.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention.
