Description

Technical Field

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

[0002] In the field of pipeline temperature control, precise temperature control of 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 scrap rate and improving production efficiency. By accurately 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, precise temperature control of the mold pipeline can also help extend the service life of the mold, because drastic changes in temperature are one of the main causes of mold wear and damage. Therefore, researching and developing more efficient and intelligent mold pipeline precise temperature control technology and systems is of great significance to modern manufacturing.

[0003] The precise temperature control of mold pipelines mainly relies on mechanical water flow distributors, which can only perform simple and imprecise 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 regulation of the flow of each pipeline and how to provide timely feedback when abnormalities occur. By introducing closed-loop control systems, data acquisition systems, workpiece quality inspections, and deep learning and training systems, precise control of the molding process and local temperature control systems can be achieved. This method not only improves the accuracy of temperature control, but also provides instant feedback when abnormalities occur in the pipeline, prompting operators to conduct inspections and maintenance.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0033] In the field of pipeline temperature control, precise temperature control of 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 scrap rate and improving production efficiency. By accurately 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, precise temperature control of the mold pipeline can also help extend the service life of the mold, because drastic changes in temperature are one of the main causes of mold wear and damage. Therefore, researching and developing more efficient and intelligent mold pipeline precise temperature control technology and systems is of great significance to modern manufacturing.

[0034] The precise temperature control of mold pipelines mainly relies on mechanical water flow distributors, which can only perform simple and imprecise 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 regulation of the flow of each pipeline and how to provide timely feedback when abnormalities occur.

This method not only improves the accuracy of temperature control, but also provides instant feedback when abnormalities occur in the pipeline, prompting operators to conduct inspections and maintenance.

[0035] In an embodiment of the present invention, a mold pipeline precision temperature control method and system are provided. This solution installs high-precision temperature sensors at key positions of water pipes to monitor the temperature changes of water flow in real time and send the data to a central processing unit or a data acquisition system to ensure the accuracy and reliability of temperature measurement.

[0036] According to a first aspect of an embodiment of the present invention, a method for precise temperature control of a mold pipeline is provided.

[0037] Figure 1 The present invention is a flowchart of a method for precise temperature control of a mold pipeline according to an embodiment of the present invention.

[0038] In one or more embodiments, preferably, the mold pipeline precise temperature control method comprises: S101, setting up a mold water channel structure and a water tank; S102. Record the time required for heating at maximum heating power under different pressures; S103, recording the water flow rate at the water system inlet; S104, adjusting the water temperature online according to the time required for temperature rise under different pressures, and recording the inlet and outlet water temperature difference; S105, after receiving the recorded inlet and outlet water temperature difference, controlling the temperature of the water stored in the water tank according to the inlet and outlet water temperature difference; S106. Display the temperature in the pipeline online.

[0039] In an embodiment of the present invention, a high-precision temperature sensor is used to monitor the temperature changes in the mold water system in real time, and a data acquisition module is used to record key data. The heating equipment is precisely adjusted in combination with the 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 temperature rise under different pressures and optimize 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 tank temperature. In addition, color coding is used to intuitively display the temperature distribution in the water pipe, which is convenient for operators to quickly identify hot spots 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.

[0040] Figure 2 It is a flow chart of setting a mold water channel structure and setting a water tank in a mold pipeline precise temperature control method according to an embodiment of the present invention.

[0041] like Figure 2 As shown, in one or more embodiments, preferably, the step of setting a mold water channel structure and setting a water tank specifically includes: S201, installing high-precision temperature sensors at key positions of the mold water channel, including the water inlet interface, the water outlet interface, and the water channel branch point near the mold cavity; S202, using a data acquisition module to collect signals from a temperature sensor at a certain frequency; S203, calculating the control amount according to the deviation between the set temperature and the actual measured temperature, and giving the control amount by using PID control; S204, when it is necessary to increase the temperature of the mold water channel, control the power of the heating device according to the temperature control strategy; S205. A water tank is provided in the flow path of the system water channel.

[0042] In an embodiment of the present invention, first, a mold water channel structure is set and equipped with a water tank. The water channel design of the mold needs to ensure that the 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 water inlet interfaces, water outlet interfaces, and water channel branch points near the mold cavity. High-precision temperature sensors are used to monitor the temperature changes of each point in real time. Next, a data acquisition module is used to collect signals from the temperature sensor 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 sensor in real time and transmit the data to the central processing unit. The control amount is calculated based on the deviation between the set temperature and the actual measured temperature, and the control amount is given using PID control. The PID controller is a commonly used closed-loop control system that 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 based on the temperature deviation to achieve precise temperature control. When the mold water channel temperature needs to be increased, the power of the heating device is controlled 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, the power of the heater will be reduced or the cooling device will be started. This dynamic adjustment ensures that the mold temperature is always maintained within the ideal range. Finally, a water tank is set in the flow path of the system water channel. The role of the water tank is to serve as a storage and buffer for heat exchange media. It can balance the heat distribution in the system and reduce temperature fluctuations caused by local overheating or overcooling. In addition, the water tank can also help remove air and other impurities in the system and protect the water pump and other sensitive components from damage.

[0043] Figure 3 It is a flow chart of recording the time required for heating at maximum heating power under different pressures in a mold pipeline precise temperature control method according to an embodiment of the present invention.

[0044] like Figure 3 As shown, in one or more embodiments, preferably, the time required for heating at the maximum heating power under different pressures is recorded, specifically including: S301, performing maximum power heating at different pressures; S302, when the water flow is 0, record the average temperature of the entire water cooling system; S303, recording the average temperature under the maximum heating power, and using curve fitting to find out the relationship between the heating time and the temperature difference.

[0045] 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.

[0046] 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.

[0047] like Figure 4 As shown, in one or more embodiments, preferably, recording the water flow rate at the water system inlet specifically includes: S401. A water pressure recorder is provided at the inlet of the water system; S402. Calculate the water flow rate according to the record of the water pressure recorder.

[0048] In an embodiment of the present invention, a water pressure recorder is provided at the water inlet of the system to monitor the pressure change of the water flow in real time. The specific steps are as follows: a high-precision water pressure recorder is installed at the water inlet of the mold water system. This device can accurately measure the water pressure flowing through this point. Ensure that the water pressure recorder is connected to the data acquisition module so that the pressure data can be transmitted to the central processing unit in real time. Start the mold water 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, which 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 properties (such as density, viscosity, etc.), the water flow velocity is calculated using the Bernoulli equation or other relevant fluid mechanics formulas. Analyze the calculated water flow velocity data, evaluate its change trend under different working conditions, and whether it meets the design requirements. If the water flow velocity is found to be abnormal or not as expected, the power of the heating equipment 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, the effectiveness of the proposed temperature control strategy and technical solution is verified.

[0049] Figure 5 It is a flow chart of a mold pipeline precise temperature control method according to an embodiment of the present invention, which adjusts the water temperature online according to the time required for temperature rise under different pressures and records the inlet and outlet water temperature difference.

[0050] like Figure 5 As shown, in one or more embodiments, preferably, the online water temperature adjustment is performed according to the time required for temperature rise under different pressures, and the inlet and outlet water temperature difference is recorded, which specifically includes: S501. The time required to obtain the temperature rise under different pressures; S502, calculating the conservative temperature rise time using the first calculation formula; S503, calculating the conservative flow rate using the second calculation formula; S504, when the flow rate is lower than the second calculation formula, there is no need to record the inlet and outlet water temperature difference, otherwise, the inlet and outlet water temperature difference is recorded; The first calculation formula is: BT=1.3×WT Among them, BT is the conservative temperature rise time, and WT is the time required for temperature rise; The second calculation formula is: V=CD÷BT Where V is the conservative flow velocity and CD is the pipe length.

[0051] In an embodiment of the present invention, the specific steps of performing online water temperature adjustment and recording the inlet and outlet water temperature difference are as follows: obtaining the time required for temperature rise under different pressures: measuring the time required for the mold water channel to heat from the initial temperature to the target temperature under different pressure conditions through experiments or actual operations, that is, the time required for temperature rise (WT). These data can be obtained in real time through high-precision temperature sensors and data acquisition modules. Calculating the conservative temperature rise time using the first calculation formula: according to the obtained time required for temperature rise (WT), using 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 that there is enough time to complete the heating process in actual operation. Calculating the conservative flow rate using the second calculation formula: based on the calculated conservative temperature rise time (BT) and the known pipeline length (CD), using the second calculation formula V=CDBT to calculate the conservative flow rate (V). This flow rate is the minimum speed requirement to ensure that the water flow cycle is completed within a given time. Determine whether it is necessary to record the inlet and outlet water temperature difference: 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 means that the water flow is insufficient to ensure effective temperature control. At this time, there is no need to record the inlet and outlet water temperature difference; on the contrary, if the actual flow rate is higher than or equal to the conservative flow rate, the inlet and outlet water temperature difference needs to be recorded to monitor the uniformity of temperature distribution and the effectiveness of the system. Record the inlet and outlet water temperature difference: When the flow rate meets the conditions, use the temperature sensor to measure the temperature at the inlet and outlet of the mold water channel respectively, and calculate the difference between the two, that is, the inlet and outlet water temperature difference. This data is crucial for evaluating system performance and optimizing temperature control strategies. Online water temperature adjustment: According to the recorded inlet and outlet water temperature difference and other relevant parameters, such as the set target temperature, current ambient temperature, etc., dynamically adjust the power or other related settings of the heating equipment to achieve more accurate temperature control. This may involve PID controllers or other advanced control system algorithms. Continuous monitoring and optimization: Throughout the process, continuously monitor the changes in key parameters and make adjustments as needed. By continuously collecting data and analyzing results, the temperature control strategy and technical solutions can be further optimized to improve the effect and efficiency of precise temperature control of the mold pipeline.

[0052] Figure 6 It is a flow chart of a mold pipeline precise temperature control method in one embodiment of the present invention, which controls the temperature of water stored in a water tank according to the inlet and outlet water temperature difference after receiving the recorded inlet and outlet water temperature difference.

[0053] like Figure 6As shown, in one or more embodiments, preferably, after receiving the recorded inlet and outlet water temperature difference, the temperature of the water stored in the water tank is controlled according to the inlet and outlet water temperature difference, specifically including: S601, determining the real-time water storage volume of the water tank, and when the water storage volume of the water tank is less than 50%, adding water; S602, calculating an updated water tank temperature given value using a third calculation formula; S603, controlling the temperature of the water storage tank according to the given temperature value of the water tank; The third calculation formula is: REF1=TC+REF0 Among them, REF1 is the updated water tank temperature set value, TC is the inlet and outlet water temperature difference, and REF0 is the water tank temperature set value before updating.

[0054] In an 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 volume of the water tank is less than 50%, the system will automatically start the water adding program to ensure that there is enough water in the water tank for temperature adjustment. The updated water tank temperature set value is calculated using the third calculation formula: after receiving the recorded inlet and outlet water temperature difference (TC), the third calculation formula REF1=TC+REF0 is used to calculate the updated water tank temperature set value (REF1). Among them, REF0 is the water tank temperature set value before the update. This formula dynamically adjusts the target temperature of the water tank based on the inlet and outlet water temperature difference to adapt to the current working conditions. The water storage tank is temperature controlled 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 by heating or cooling equipment to reach the new target temperature. This may involve starting an electric heater, a Peltier element or other heating / cooling technology. 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: Throughout the process, the system will continuously monitor the temperature and water level changes of the water tank and make adjustments as needed. For example, if the water temperature is found to deviate 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: In order to facilitate subsequent analysis and optimization, it is recommended to record the process and results of each temperature adjustment, including the initial temperature of the water tank, the target temperature, the actual temperature change curve, and the handling measures for any abnormal situations. These data can help engineers better understand the operating characteristics of the system and make adjustments and improvements when necessary.

[0056] like Figure 7 As shown, in one or more embodiments, preferably, the online display of the temperature in the pipeline specifically includes: S701, recording each temperature in the water pipe; S702, setting the colors of different temperatures according to high and low; S703: Visually display the colors.

[0057] In the embodiment of the present invention, first, high-precision temperature sensors need to be installed at key locations 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 data acquisition system. Ensure that the arrangement of sensors can cover the key areas of the entire water pipe system so as to obtain comprehensive water temperature information. Set different temperatures according to high and low colors: In order to more intuitively display the temperature distribution, color coding can be used. 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 color gradually changes from low temperature to high temperature (such as blue for low temperature and red for high temperature). According to the temperature value measured in real time, the corresponding color is assigned to different positions in the water pipe. Visualize the color: Use graphical user interface (GUI) software or special data visualization tools to display the color-coded water pipe temperature information in a graphical form. This can be in the form of a two-dimensional plane map, a three-dimensional stereogram, or a dynamic video stream. In this way, the operator can intuitively see the temperature distribution of 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 temperature control strategies and technical solutions.

Fig. 9 , the electronic device includes a plurality of acquisition devices 901 and a processing device 902; wherein different acquisition devices 901 monitor different areas of a target scene, and the monitoring areas of the plurality of acquisition devices cover the target scene; Each acquisition device 901 is used to acquire an image of a target scene and identify the position information of a moving target in the acquired image; The processing device 902 includes a processor 903, a communication interface 904, a memory 905 and a communication bus 906, wherein the processor 903, the communication interface 904 and the memory 905 communicate with each other via the communication bus 906. Memory 905, used for storing computer programs; The processor 903 is used to implement any of the above-mentioned mold pipeline precise temperature control method steps provided by the embodiments of the present invention when executing the computer program stored in the memory 905.

[0068] The technical solution provided by the embodiments of the present invention may have the following beneficial effects: In the scheme of the present invention, in order to more intuitively display the temperature distribution, a color coding method can be used. 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 color gradually changes from low temperature to high temperature (such as blue for low temperature, red for high temperature). According to the temperature value measured in real time, the corresponding color is assigned to different positions in the water pipe. This technology allows the operator to intuitively see the temperature distribution of each point in the water pipe and quickly identify possible hot spots or cold spots. In addition, a comprehensive analysis can be performed in combination with other parameters (such as flow rate, pressure, etc.) to optimize the temperature control strategy and technical solution.

[0069] In the present invention, the system continuously monitors the temperature and water level changes of the water tank throughout the process and makes adjustments as needed. For example, if the water temperature is found to deviate 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. This technology ensures the flexibility and adaptability of the system and can cope with changes in various complex working conditions.
