Description

Technical Field

[0001] The present invention relates to the technical field of pipeline temperature control, and more specifically, to a precise temperature control method and system for a mold pipeline. Background Art

[0002] In the field of pipeline temperature control, the precise temperature control method for a mold pipeline usually involves using advanced temperature sensors and control systems. These systems can monitor and adjust the temperature of the mold in real time to ensure the stability and uniformity of the temperature during the production process. This precise temperature control is of great significance for improving product quality, reducing the rejection rate, and enhancing production efficiency. By precisely controlling the temperature of the mold, product defects caused by temperature fluctuations, such as deformation, shrinkage marks, or internal stress, can be avoided. In addition, the precise temperature control of the mold pipeline also helps to extend the service life of the mold, because drastic temperature changes are one of the main reasons for mold wear and damage. Therefore, researching and developing more efficient and intelligent precise temperature control technologies and systems for mold pipelines is of extremely important significance for modern manufacturing.

[0003] The precise temperature control of the mold pipeline mainly relies on mechanical water distributors, which can only perform simple and inaccurate flow display and control. This method cannot meet the growing demand for high-precision and intelligent products. Especially when dealing with abnormal situations such as pipe circuit blockage and leakage, there is a lack of effective prompts and countermeasures. The technical difficulties mainly include how to achieve precise adjustment of the flow rate of each pipeline and how to provide timely feedback when abnormalities occur. By introducing a closed-loop control system, a data acquisition system, workpiece quality inspection, and a deep learning and training system, precise control of the forming process and the local temperature control system can be achieved. This method not only improves the accuracy of temperature control but also provides immediate feedback when abnormalities occur in the pipeline, prompting the operator to conduct inspections and maintenance.

[0058] The technical solutions provided by the embodiments of the present invention may include the following beneficial effects:

[0059] In the solution of the present invention, in order to more intuitively display the temperature distribution, a color coding method can be adopted. For example, a temperature range (such as the lowest temperature to the highest temperature) can be set, and this range can be divided into several intervals. Each interval corresponds to a color, and the colors gradually change from low temperature to high temperature (such as blue represents low temperature and red represents high temperature). According to the real-time measured temperature values, the corresponding colors are assigned to different positions in the water pipe. This technology enables the operator to intuitively see the temperature distribution at each point in the water pipe and quickly identify possible hot or cold spot areas. In addition, other parameters (such as flow rate, pressure, etc.) can be combined for comprehensive analysis to optimize the temperature control strategy and technical solution.

[0060] In the present invention, throughout the process, the system continuously monitors the temperature and water level changes of the water tank and makes adjustments as needed. For example, if it is found that the water temperature deviates too much from the target value, the power of the heating or cooling equipment can be increased; if the water level is too low, water needs to be replenished in a timely manner. In addition, other sensor data (such as ambient temperature, humidity, etc.) can be combined to further optimize the temperature control strategy. This technology ensures the flexibility and adaptability of the system and can cope with various complex working conditions.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0075] In the field of pipeline temperature control, the precise temperature control method for mold pipelines usually involves the use of advanced temperature sensors and control systems. These systems can monitor and adjust the temperature of the mold in real time to ensure the stability and uniformity of the temperature during the production process. This precise temperature control is of great significance for improving product quality, reducing the scrap rate, and enhancing production efficiency. By precisely controlling the temperature of the mold, product defects caused by temperature fluctuations, such as deformation, shrinkage marks, or internal stress, can be avoided. In addition, the precise temperature control of the mold pipeline also helps to extend the service life of the mold, because drastic temperature changes are one of the main reasons for mold wear and damage. Therefore, researching and developing more efficient and intelligent precise temperature control technologies and systems for mold pipelines is of extremely important significance for modern manufacturing.

[0076] Precise temperature control of the mold pipeline mainly relies on mechanical water distributors, which can only perform simple and inaccurate flow display and control. This method cannot meet the growing demand for high-precision and intelligent products. Especially when dealing with abnormal situations such as pipeline blockage and leakage, there is a lack of effective prompts and countermeasures. The technical difficulties mainly include how to achieve precise adjustment of the flow rate of each pipeline and how to timely feedback information when abnormalities occur. By introducing a closed-loop control system, a data acquisition system, workpiece quality inspection, and a deep learning and training system, precise control of the molding process and the local temperature control system is achieved. This method not only improves the accuracy of temperature control but also can instantaneously feedback when abnormalities occur in the pipeline, prompting the operator to conduct inspections and maintenance.

[0077] In an embodiment of the present invention, a method and system for precise temperature control of a mold pipeline are provided. High-precision temperature sensors are installed at key positions of the water pipes to continuously monitor the temperature changes of the water flow and send the data to the central processing unit or the data acquisition system to ensure the accuracy and reliability of temperature measurement.

[0078] According to the first aspect of the embodiment of the present invention, a method for precise temperature control of a mold pipeline is provided.

[0079] Figure 1 It is a flowchart of a method for precise temperature control of a mold pipeline according to an embodiment of the present invention.

[0080] In one or more embodiments, preferably, the method for precise temperature control of a mold pipeline includes:

[0081] S101. Set the mold waterway structure and set up a water tank;

[0082] S102. Record the time required for temperature rise at the maximum heating power under different pressures;

[0083] S103. Record the water flow velocity at the inlet of the water system;

[0084] S104. Perform online water temperature adjustment according to the time required for temperature rise under different pressures and record the temperature difference between the inlet and outlet;

[0085] S105. After receiving the recorded temperature difference between the inlet and outlet, perform temperature control of the water stored in the water tank according to the temperature difference between the inlet and outlet;

[0086] S106. Display the temperature in the pipeline online.

[0087] In an embodiment of the present invention, the temperature change in the mold waterway system is monitored in real time by a high-precision temperature sensor, and key data is recorded by a data acquisition module. The heating equipment is precisely adjusted in combination with a PID control algorithm to ensure that the water temperature reaches the preset target. At the same time, the system can automatically adjust the water temperature according to the time required for the temperature rise under different pressures, optimizing the temperature control strategy. When the water storage in the water tank is less than 50%, the system will automatically add water and adjust the water temperature in the water tank. In addition, the temperature distribution in the water pipe is visually displayed in a color-coded manner, facilitating the operator to quickly identify hot or cold spots. Throughout the process, the system continuously monitors and adjusts various parameters to ensure the effect and efficiency of precise temperature control of the mold pipeline.

[0088] Figure 2 It is a flowchart of setting the mold waterway structure and setting the water tank in a method for precise temperature control of a mold pipeline according to an embodiment of the present invention.

[0089] As Figure 2 shown, in one or more embodiments, preferably, the setting of the mold waterway structure and setting the water tank specifically includes:

[0090] S201. Install high-precision temperature sensors at key positions of the mold waterway. The key positions include the water inlet interface, the water outlet interface, and the waterway branch points near the mold cavity;

[0091] S202. Use the data acquisition module to collect the signals of the temperature sensors at a certain frequency;

[0092] S203. Calculate the control quantity based on the deviation between the set temperature and the actually measured temperature, and use the PID control to give the control quantity;

[0093] S204. When it is necessary to increase the temperature of the mold waterway, control the power of the heating equipment according to the temperature control strategy;

[0094] S205. Set a water tank in the flow path of the system waterway.

[0095] In an embodiment of the present invention, first, a mold waterway structure is set up and a water tank is equipped. The waterway design of the mold needs to ensure that water flow can be evenly distributed to all parts of the mold to achieve uniform temperature control. High-precision temperature sensors are installed at key positions, including the water inlet interface, the water outlet interface, and the waterway branch points near the mold cavity. The high-precision temperature sensors are used to monitor the temperature changes at each point in real time. Next, a data acquisition module is used to collect the signals of the temperature sensors at a certain frequency. The data acquisition module can be a PLC (Programmable Logic Controller) or a DCS (Distributed Control System), and its function is to collect data from the temperature sensors in real time and transmit this data to the central processing unit. Calculate the control quantity according to the deviation between the set temperature and the actually measured temperature, and use PID control to give the control quantity. The PID controller is a commonly used closed-loop control system. It adjusts the control variable by calculating the error between the set value and the actual value, so that the system reaches the desired state. In this embodiment, the PID controller calculates the power adjustment value of the heating device or the cooling device according to the temperature deviation to achieve precise temperature control. When it is necessary to increase the temperature of the mold waterway, control the power of the heating device according to the temperature control strategy. For example, if the temperature near the mold cavity is detected to be lower than the set value, the PID controller will increase the power of the heater; conversely, if the temperature is higher than the set value, it will reduce the power of the heater or start the cooling device. This dynamic adjustment ensures that the mold temperature is always maintained within the ideal range. Finally, a water tank is set up in the flow path of the system waterway. The role of the water tank is to store and buffer the heat exchange medium. It can balance the heat distribution in the system and reduce the temperature fluctuations caused by local overheating or overcooling. In addition, the water tank can also help to remove air and other impurities in the system and protect the water pump and other sensitive components from damage.

[0096] Figure 3 It is a flowchart of recording the time required for temperature rise at the maximum heating power under different pressures in a method for precise temperature control of a mold pipeline in an embodiment of the present invention.

[0097] As Figure 3 shown, in one or more embodiments, preferably, the recording of the time required for temperature rise at the maximum heating power under different pressures specifically includes:

[0098] S301. Perform maximum power heating under different pressures respectively;

[0099] S302. Record the average temperature of the entire water cooling system when the water flow is 0;

[0100] S303. Record the average temperature at the maximum heating power and use curve fitting to obtain the relationship between the temperature rise duration and the temperature difference.

[0101] In an embodiment of the present invention, under different pressure conditions, an experiment is conducted to record the time required for the mold water circuit to heat up under the maximum heating power. The specific steps are as follows: The pressure of the mold water circuit system is set to different values ​​(for example, 0.5 bar, 1.0 bar, 1.5 bar, etc.). Under each pressure condition, the heating device is started and adjusted to the maximum heating power. A high-precision temperature sensor is used to monitor the temperature change in the mold water circuit in real time. The time from the start of heating to reaching the preset temperature, that is, the time required for heating, is recorded. Under different pressures, experiments with maximum power heating are conducted respectively. The specific steps are as follows: The pressure of the mold water circuit system is set to different values ​​(for example, 0.5 bar, 1.0 bar, 1.5 bar, etc.). Under each pressure condition, the heating device is started and adjusted to the maximum heating power. The temperature change during the heating process is recorded until a steady state or a preset maximum heating time is reached. When the water flow is 0, the average temperature of the entire water cooling system is measured. The specific steps are as follows: Make sure that there is no water flow through the mold water circuit system (which can be achieved by closing the valve). Start the heating device and adjust it to the maximum heating power. Wait for a period of time for the entire system to reach a thermal equilibrium state. Use high-precision temperature sensors to measure the temperature of each key position in the water cooling system. Calculate the average temperature of all measurement points, which is the average temperature of the entire water cooling system. Record the average temperature at the maximum heating power, and use curve fitting to find the relationship between the heating time and the temperature difference. The specific steps are as follows: At the maximum heating power, record the heating time at different initial temperatures. Calculate the temperature difference in each experiment (that is, the difference between the final temperature and the initial temperature). Summarize all experimental data, including the temperature difference and the corresponding heating time. Use mathematical software (such as MATLAB, Python, etc.) to perform curve fitting to find the functional relationship between the heating time and the temperature difference. Common fitting methods include linear regression, polynomial regression, etc. Based on the fitting results, a mathematical model can be obtained to predict the heating time under different temperature differences.

[0102] Figure 4 It is a flow chart of recording water flow velocity at the inlet of a water system in a method for precise temperature control of a mold pipeline according to an embodiment of the present invention.

[0103] like Figure 4 As shown, in one or more embodiments, preferably, recording the water flow rate at the water system inlet specifically includes:

[0104] S401. A water pressure recorder is provided at the inlet of the water system;

[0105] S402. Calculate the water flow rate according to the record of the water pressure recorder.

[0106] In an embodiment of the present invention, a water pressure recorder is provided at the inlet of the system water to monitor the pressure change of the water flow in real time. The specific steps are as follows: Install a high-precision water pressure recorder at the inlet of the mold waterway system. This device can accurately measure the water flow pressure passing through this point. Ensure that the water pressure recorder is connected to the data acquisition module to transmit the pressure data to the central processing unit in real time. Start the mold waterway system and let it run normally for a period of time to ensure that the system reaches a stable state. Use the data acquisition module to record the output of the water pressure recorder, and these data will be used for subsequent flow rate calculations. According to the records of the water pressure recorder, combined with the known pipe size and fluid characteristics (such as density, viscosity, etc.), use Bernoulli's equation or other relevant fluid mechanics formulas to calculate the water flow velocity. Analyze the calculated water flow velocity data, evaluate its change trend under different working conditions, and whether it meets the design requirements. If it is found that the water flow velocity is abnormal or does not meet the expectations, the power of the heating device can be adjusted or other measures can be taken to optimize the water flow conditions. Finally, by comparing the water flow velocity data before and after the experiment, verify the effectiveness of the proposed temperature control strategy and technical solution.

[0107] Figure 5 It is a flowchart of online water temperature adjustment according to the time required for temperature rise under different pressures and recording the water temperature difference between the inlet and outlet in a precise temperature control method for a mold pipeline in an embodiment of the present invention.

[0108] As Figure 5 shown, in one or more embodiments, preferably, the online water temperature adjustment according to the time required for temperature rise under different pressures and recording the water temperature difference between the inlet and outlet specifically includes:

[0109] S501. Obtain the time required for temperature rise under different pressures;

[0110] S502. Calculate the conservative temperature rise time using the first calculation formula;

[0111] S503. Calculate the conservative flow rate using the second calculation formula;

[0112] S504. When the flow rate is lower than the second calculation formula, there is no need to record the water temperature difference between the inlet and outlet; otherwise, record the water temperature difference between the inlet and outlet;

[0113] The first calculation formula is:

[0114] BT = 1.3×WT

[0115] Wherein, BT is the conservative temperature rise time, and WT is the time required for temperature rise;

[0116] The second calculation formula is:

[0117] V = CD÷BT

[0118] Wherein, V is the conservative flow rate and CD is the pipe length.

[0119] In the embodiment of the present invention, the specific steps for online water temperature adjustment and recording the water temperature difference between the inlet and outlet are as follows: Obtain the time required for temperature rise under different pressures: Through experiments or actual operations, measure the time required for the mold waterway to heat from the initial temperature to the target temperature under different pressure conditions, that is, the time required for temperature rise (WT). These data can be obtained in real time through a high-precision temperature sensor and a data acquisition module. Calculate the conservative temperature rise time using the first calculation formula: According to the obtained time required for temperature rise (WT), use the first calculation formula BT = 1.3×WT; to calculate the conservative temperature rise time (BT). This formula assumes a certain safety factor to ensure sufficient time to complete the heating process during actual operation. Calculate the conservative flow rate using the second calculation formula: Based on the calculated conservative temperature rise time (BT) and the known pipe length (CD), use the second calculation formula V = CD / BT to calculate the conservative flow rate (V). This flow rate is the minimum speed requirement to ensure the completion of the water flow cycle within a given time. Determine whether to record the water temperature difference between the inlet and outlet: Compare the actually measured flow rate with the calculated conservative flow rate. If the actual flow rate is lower than the conservative flow rate, it indicates that the water flow is insufficient to ensure effective temperature control, and in this case, there is no need to record the water temperature difference between the inlet and outlet; on the contrary, if the actual flow rate is higher than or equal to the conservative flow rate, it is necessary to record the water temperature difference between the inlet and outlet to monitor the uniformity of the temperature distribution and the effectiveness of the system. Record the water temperature difference between the inlet and outlet: When the flow rate meets the conditions, use a temperature sensor to measure the temperatures at the inlet and outlet of the mold waterway respectively, and calculate the difference between the two, that is, the water temperature difference between the inlet and outlet. This data is crucial for evaluating the system performance and optimizing the temperature control strategy. Online water temperature adjustment: According to the recorded water temperature difference between the inlet and outlet and other relevant parameters, such as the set target temperature, the current ambient temperature, etc., dynamically adjust the power of the heating device or other relevant settings to achieve more precise temperature control. This may involve a PID controller or other advanced control system algorithms. Continuous monitoring and optimization: During the whole process, continuously monitor the changes of key parameters and make adjustments as needed. By continuously collecting data and analyzing the results, the temperature control strategy and technical solution can be further optimized to improve the effect and efficiency of precise temperature control of the mold pipeline.

[0120] Figure 6 It is a flowchart of temperature control of the water stored in the water tank according to the recorded water temperature difference between the inlet and outlet in a method for precise temperature control of a mold pipeline in an embodiment of the present invention.

[0121] As Figure 6 shown, in one or more embodiments, preferably, after receiving the recorded water temperature difference between the inlet and outlet, the temperature control of the water stored in the water tank according to the water temperature difference between the inlet and outlet specifically includes:

[0122] S601. Determine the real-time water storage in the water tank. When the water storage in the water tank is lower than 50%, add water.

[0123] S602. Calculate the updated water tank temperature set value using the third calculation formula.

[0124] S603. Control the temperature of the water storage tank according to the water tank temperature set value.

[0125] The third calculation formula is:

[0126] REF1 = TC + REF0

[0127] Where REF1 is the updated water tank temperature set value, TC is the temperature difference between the inlet and outlet water, and REF0 is the water tank temperature set value before update.

[0128] In the embodiment of the present invention, first, a water level sensor needs to be installed or other methods are used to monitor the real-time water level in the water tank. When it is detected that the water storage in the water tank is lower than 50%, the system will automatically start the water addition program to ensure that there is enough water in the water tank for temperature regulation. Calculate the updated water tank temperature set value using the third calculation formula: After receiving the recorded temperature difference between the inlet and outlet water (TC), use the third calculation formula REF1 = TC + REF0; to calculate the updated water tank temperature set value (REF1). Where REF0 is the water tank temperature set value before update. This formula dynamically adjusts the target temperature of the water tank based on the temperature difference between the inlet and outlet water to adapt to the current working conditions. Control the temperature of the water storage tank according to the water tank temperature set value: Once the new water tank temperature set value is calculated, it is necessary to adjust the water temperature in the water tank through heating or cooling equipment to make it reach the new target temperature. This may involve starting an electric heater, a Peltier element, or other heating / cooling technologies. At the same time, it is also necessary to ensure that the water temperature in the water tank is evenly distributed to avoid local overheating or overcooling. Continuous monitoring and adjustment: During the whole process, the system will continuously monitor the temperature and water level changes in the water tank and make adjustments as needed. For example, if it is found that the water temperature deviates too much from the target value, the power of the heating or cooling equipment can be increased; if the water level is too low, water needs to be replenished in time. In addition, other sensor data (such as ambient temperature, humidity, etc.) can be combined to further optimize the temperature control strategy. Recording and feedback: For the convenience of subsequent analysis and optimization, it is recommended to record the process and results of each temperature adjustment, including the initial temperature, target temperature, actual temperature change curve of the water tank, and the handling measures for any abnormal situations, etc. These data can help engineers better understand the operating characteristics of the system and make adjustments and improvements when necessary.

[0129] Figure 7 It is a flowchart for online display of the temperature in the pipeline in a method for precise temperature control of the die pipeline in an embodiment of the present invention.

[0130] As Figure 7 shown, in one or more embodiments, preferably, the online display of the temperature in the pipeline specifically includes:

[0131] S701. Record each temperature in the water pipe;

[0132] S702. Set colors for different temperatures according to high and low;

[0133] S703. Visualize the colors.

[0134] In the embodiments of the present invention, first, high-precision temperature sensors need to be installed at key positions of the water pipe. These sensors can monitor the temperature changes of the water flow in real time and send the data to the central processing unit or the data acquisition system. Ensure that the arrangement of the sensors can cover the key areas of the entire water pipe system to obtain comprehensive water temperature information. Set colors for different temperatures according to high and low: In order to more intuitively display the temperature distribution, a color coding method can be adopted. For example, a temperature range (such as the lowest temperature to the highest temperature) can be set, and this range is divided into several intervals. Each interval corresponds to a color, and the colors gradually change from low temperature to high temperature (such as blue for low temperature and red for high temperature). According to the real-time measured temperature values, the corresponding colors are assigned to different positions in the water pipe. Visualize the colors: Use a graphical user interface (GUI) software or a dedicated data visualization tool to display the color-coded water pipe temperature information in a graphical form. This can be in the form of a two-dimensional plan view, a three-dimensional stereogram, or a dynamic video stream, etc. In this way, the operator can intuitively see the temperature distribution at each point in the water pipe and quickly identify possible hot or cold spots. In addition, other parameters (such as flow rate, pressure, etc.) can be combined for comprehensive analysis to optimize the temperature control strategy and technical solution.
