Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of temperature control of a mold temperature controller, and in particular to a temperature control system and method of a mold temperature controller. Background Art
[0002] As a key temperature control equipment in the injection molding process, the mold temperature controller is widely used in the production and manufacturing of various plastic products. The main function of the mold temperature controller is to achieve temperature regulation in the molding process of plastic products by controlling the temperature of the mold, thereby ensuring the consistency of product quality and the stability of the processing technology. With the development of industrial automation and intelligence, higher requirements are placed on the temperature control accuracy and response speed of the mold temperature controller to adapt to the complex and changeable production environment and diversified product needs.
[0003] The mold temperature controller usually has multiple pipe systems inside, which are responsible for transporting heat media (such as water, steam, oil, etc.) to control the temperature of the mold. The number and layout of the pipes depend on the design and purpose of the mold temperature controller. If a pipe has an abnormal temperature, it may mean that the heat medium flow of the pipe is insufficient, the pipe is blocked, or the equipment is faulty.
[0004] Existing temperature control systems for mold temperature controllers usually rely on temperature sensors to monitor mold temperature. However, in actual applications, temperature anomalies of mold temperature controllers are often caused by insufficient flow or blockage of the medium in the internal piping system. Existing systems for controlling the temperature of the internal piping of mold temperature controllers often lack intelligent fault detection and response mechanisms, resulting in a decrease in the temperature control accuracy of the mold temperature controller, which in turn affects the consistency of product quality and may even cause production safety hazards. Summary of the invention
[0005] In view of the problems existing in the above-mentioned prior art, the object of the present invention is to provide a temperature control system and method for a mold temperature controller, so as to perform an intelligent fault detection and response mechanism for the temperature of the internal pipeline of the mold temperature controller, thereby improving the temperature control accuracy of the mold temperature controller.
[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solution: a temperature control system of a mold temperature controller, comprising: The temperature monitoring module establishes a medium temperature control database and monitors the mold temperature in each pipeline by configuring a temperature sensor in each pipeline of the mold temperature controller to obtain the temperature data of the mold in multiple pipelines; The temperature comparison module compares the uploaded temperature data with the control temperature data required by the corresponding mold in the database, obtains the temperature control difference between each section of the medium and the medium in the database, and compares the temperature control difference with the control value, and responds accordingly based on the comparison result; The continuous monitoring module executes an external cooling strategy when the temperature control difference exceeds the regulation threshold, so that the temperature control difference can be reduced within the adjustable threshold. The fault judgment module continuously monitors whether the temperature control difference data changes after the temperature control difference can be reduced within the adjustable threshold. When a change occurs, it notifies the maintenance personnel to inspect and maintain the pipeline.
[0007] In some embodiments, the external cooling strategy includes increasing the fan speed of the mold temperature controller or other ways to increase air flow to continuously cool the external temperature of the pipeline.
[0008] In some embodiments, after the temperature comparison module compares the temperature control difference with the regulation value range, the pipeline with a temperature control difference greater than the regulation value in the monitored pipeline is marked as an adjustable pipeline.
[0009] In some embodiments, a controllable threshold is set in the continuous detection module to determine the operation of the adjustable pipeline. The comparison between the temperature control difference and the controllable threshold is used to determine whether to execute the external cooling strategy on the adjustable pipeline or mark it as a faulty pipeline, and then notify the maintenance personnel to inspect and maintain the pipeline.
[0010] In some embodiments, the specific method for obtaining the allowable temperature difference based on the temperature value monitored in the faulty pipeline segment is as follows: The actual temperature difference Nw = Sw - Gw is obtained by subtracting the operation control temperature Gw in the temperature control database from the temperature value Sw monitored in the faulty pipeline segment. The regulation value is S, and the allowable temperature difference Yw = S + α×(Nw - S) is obtained by combining the actual temperature difference Nw with the adjustment coefficient α. Then, the operation temperature difference between adjacent pipelines is compared with the allowable temperature difference.
[0011] In some embodiments, if the operation temperature difference between adjacent pipelines is greater than the allowable temperature difference, it indicates that the faulty pipeline is indeed a faulty pipeline, and the maintenance personnel are notified to inspect and maintain the pipeline. If the operation temperature difference between adjacent pipelines is less than or equal to the allowable temperature difference, the faulty pipeline is judged as an adjustable pipeline, and the external cooling strategy is executed on it.
[0012] In some embodiments, if the operation temperature difference between adjacent pipelines is greater than the allowable temperature difference, it indicates that the faulty pipeline is indeed a faulty pipeline, and the maintenance personnel are notified to inspect and maintain the pipeline. If the operation temperature difference between adjacent pipelines is less than or equal to the allowable temperature difference, it indicates that the judgment of the faulty pipeline is caused by the abnormal temperature of the adjacent pipeline. The faulty pipeline is judged as an adjustable pipeline, and the external cooling strategy is executed on it.
[0013] In some embodiments, a reasonable fluctuation threshold is set, and the adjacent pipes on both sides of the faulty pipe are compared to obtain the temperature difference between the adjacent pipes. By comparing the adjacent temperature difference with the reasonable fluctuation threshold, it is determined whether to mark the adjacent pipes as high-temperature pipes.
[0014] The present invention also provides the following technical solutions: The present invention further provides a method for controlling the temperature of a mold temperature controller. The method is used to implement the above-mentioned mold temperature control system. The method includes the following steps: establishing a medium temperature control database, monitoring the mold temperature in each pipe in the mold temperature controller by configuring temperature sensors in each pipe to obtain the temperature data of the molds in multiple sections of pipes; comparing the uploaded temperature data with the corresponding control temperature data required by the molds in the database to obtain the temperature control difference between each section of the medium and the medium in the database, and comparing the size of the temperature control difference with the regulation value, and making corresponding responses according to the comparison results; when the temperature control difference exceeds the regulation threshold, execute an external cooling strategy to make the temperature control difference can be reduced within the adjustable threshold; after the temperature control difference can be reduced within the adjustable threshold, continuously monitor whether there is any change in the temperature control difference data. When a change occurs, notify the maintenance personnel to check and maintain the pipes.
[0015] The present invention further provides a computer-readable storage medium. The computer-readable storage medium stores a computer program, and the computer program is executed by a processor to implement the above-mentioned mold temperature control system.
[0016] The technical solutions provided by the present invention have the following beneficial effects compared with the prior art: First, in the present invention, by establishing a medium temperature control database and monitoring the temperature of each pipe in real time, the mold temperature can be effectively and accurately regulated to ensure that the mold is within the set optimal working temperature range, thereby improving the quality consistency of the products. Moreover, the system can dynamically compare the real-time monitored data with the preset regulation value. When the temperature control difference exceeds the reasonable range, the system can quickly respond and implement an external cooling strategy to maintain the mold temperature within a safe and controllable range.
[0017] Second, in the present invention, by setting a controllable threshold and a maximum tolerance value, the system can reduce excessive adjustment operations under unnecessary circumstances, reduce energy waste, and achieve more efficient resource utilization. At the same time, in the analysis of the temperature influence of the faulty pipe on the adjacent pipes, the system can give priority to identifying and processing the affected pipes to ensure the stability and reliability of the entire temperature control system. The system can automatically evaluate and optimize the temperature control strategy during the continuous adjustment process to achieve continuous improvement of the temperature control system and adapt to the demand changes under different production conditions. BRIEF DESCRIPTION OF THE DRAWINGS
[0018] Figure 1 It is a schematic diagram of the modules of the system of the present invention; Figure 2 It is a schematic flow diagram of the method of the present invention. Specific embodiments
[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. 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 of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.
[0020] It can be understood that the term "one" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of the element can be multiple. The term "one" cannot be understood as a limitation on the number.
[0021] The present invention provides a temperature control system for a mold temperature machine, as Figure 1 and Figure 2 shown, including: A temperature monitoring module that establishes a control database for the medium temperature. The database contains the control temperature data required for various molds of the mold temperature machine. At the same time, temperature sensors are installed through multiple sections of pipelines of the mold temperature machine to monitor the temperature of the molds in each pipeline, so as to obtain the temperature data of the molds in multiple sections of pipelines, and upload the temperature data obtained by the temperature sensors to the database.
[0022] A temperature comparison module compares the uploaded temperature data with the control temperature data required for the corresponding molds in the database to obtain the temperature control difference between each section of the medium and the database medium. The temperature control difference represents the accuracy of the temperature control of the mold temperature machine. Set the adjustment value. If the temperature control difference range is within the adjustment value, it is accurate. The closer its value is to 0, the more it represents precise control, which can effectively ensure the product quality. If its value is outside the adjustment value, it means that the control accuracy decreases, which may cause fluctuations and inconsistencies in the product quality. When the temperature control difference of the mold in the monitored pipeline is less than the adjustment value, it is determined that the mold temperature machine can perform temperature regulation work on the mold, and the mold temperature machine does not make additional responses. When the temperature control difference in the monitored pipeline is greater than the adjustment value, the corresponding pipeline is marked as an adjustable pipeline and continuously monitored.
[0023] The continuous monitoring module continuously monitors the adjustable pipeline, sets a controllable threshold. When the temperature control difference is within the controllable threshold range, it indicates that the temperatures of all pipelines are under reasonable operating conditions, and then an external cooling strategy is implemented for the adjustable pipeline. When the temperature control difference exceeds the controllable threshold range, it indicates that the adjustable pipeline cannot be cooled under the external cooling strategy, and the adjustable pipeline is marked as a faulty pipeline. For example, in the temperature control database, the controlled temperature for mold operation is 50 °C, the controllable threshold is 3 °C, and the temperature of a pipeline section is monitored to be 54 °C. The difference between its temperature and the operating temperature in the database is 4 °C. Since it exceeds the adjustable threshold of 3 °C, it is marked as a faulty pipeline.
[0024] The fault judgment module continuously monitors whether the temperature control difference data of each pipeline changes after the temperature control difference of the mold in the pipeline can be reduced to the regulated value. If there is no change, it indicates that after implementing the external cooling strategy, the pipeline temperature has returned to the controllable state, and it can be judged that the abnormal pipeline temperature is affected by a single factor of the external temperature and no reaction is made. If there is a change, it indicates that after implementing the external cooling strategy, the pipeline temperature is still in a fluctuating state, then it is judged that the abnormal pipeline temperature is not only affected by the external temperature, and the maintenance personnel are notified to check and maintain the pipeline.
[0025] The external cooling strategy includes increasing the fan speed of the mold temperature controller or other ways to increase air flow to continuously cool the external temperature of the pipeline. After the external cooling strategy is executed for the preset time, if the temperature control difference can be reduced to the regulated value, the fault judgment module is executed. If the temperature control difference still cannot be reduced to the regulated value, it indicates that the abnormal pipeline temperature is not affected by the external environmental temperature, and the maintenance personnel are notified to check and maintain the pipeline.
[0026] Generally speaking, for the above, the mold temperature control system of this mold temperature controller ensures the precise control of the mold temperature through a multi-level monitoring and adjustment mechanism, improving product quality. First, the system uses the temperature monitoring module to collect the mold temperature data in real time through temperature sensors installed in multiple pipeline segments and uploads it to the temperature control database. The temperature comparison module compares the real-time data with the control temperature in the database, calculates the temperature control difference, and judges its accuracy. If the temperature difference exceeds the preset regulated value, the system marks the pipeline as an adjustable pipeline and enters the continuous monitoring stage. The continuous monitoring module decides whether to start an external cooling strategy, such as increasing the fan speed, for temperature adjustment based on whether the temperature control difference is within the controllable threshold. If the cooling strategy is ineffective and the temperature difference does not recover, it enters the fault judgment module, and the maintenance personnel are notified to check whether there are other problems with the pipeline. Through this series of monitoring, adjustment, and judgment steps, the system can effectively control the mold temperature, ensure the temperature control accuracy during the production process, timely detect and eliminate faults, and guarantee the consistency and stability of product quality.
[0027] In addition, when the pipeline is determined to be a faulty pipeline section, since the faulty pipeline may be affected by the temperature of adjacent pipelines, resulting in misjudgment. After the pipeline is determined to be a faulty pipeline, the allowable temperature difference is obtained from the temperature value monitored for the faulty pipeline section, the operating temperature difference of the adjacent pipeline of the faulty pipeline section is obtained, the operating temperature difference of the adjacent pipeline is compared with the allowable temperature difference, and corresponding actions are taken according to the comparison result. The specific method for obtaining the allowable temperature difference from the temperature value monitored for the faulty pipeline section is as follows: The difference between the temperature value Sw monitored for the faulty pipeline section and the operating control temperature Gw in the temperature control database is calculated to obtain the actual temperature difference Nw = Sw - Gw, and the regulation value is S. The allowable temperature difference Yw = S + α×(Nw - S) is obtained by combining the actual temperature difference Nw with the adjustment coefficient α. After comparing the operating temperature difference of the adjacent pipeline with the allowable temperature difference, if the operating temperature difference of the adjacent pipeline is greater than the allowable temperature difference, the judgment of the faulty pipeline is maintained, and the maintenance personnel are notified to inspect and maintain the pipeline. If the operating temperature difference of the adjacent pipeline is less than or equal to the allowable temperature difference, the faulty pipeline is caused by the abnormal temperature of the adjacent pipeline. The faulty pipeline is re-marked as an adjustable pipeline, and an external cooling strategy is implemented for it. For example, assume the temperature value of the faulty pipeline section is 55 °C, the temperature value of the adjacent operating pipeline is 54 °C, the operating control temperature is 50 °C, the regulation value is 3 °C, the actual temperature difference is 55 °C - 50 °C = 5 °C, the allowable temperature difference is 4 °C, and the operating temperature difference of the adjacent pipeline is 4 °C. At this time, the operating temperature difference of the adjacent pipeline is equal to the allowable temperature difference, so the pipeline is re-marked as an adjustable pipeline and an external cooling strategy is implemented for it because the adjacent pipelines are closely connected. This solution aims to solve the problem that high-entropy alloy pipelines may be misjudged due to the influence of adjacent pipeline temperatures in the temperature control system. When a pipeline section is determined to be a faulty pipeline, the system will analyze the temperature value of the pipeline and the temperature difference of its adjacent pipelines to reduce misjudgments caused by adjacent pipeline influences, thereby optimizing the temperature control strategy. First, when a pipeline section is determined to be a faulty pipeline, its temperature value needs to be further analyzed. By calculating the difference between the temperature value Sw monitored for the faulty pipeline section and the operating control temperature Gw in the temperature control database, the actual temperature difference Nw = Sw - Gw of the pipeline can be obtained. Then, by combining the adjustment coefficient α and the regulation value S, the allowable temperature difference is calculated. This allowable temperature difference is used as a judgment criterion to ensure the accuracy of the temperature control strategy. Next, the system will analyze the operating temperature difference of the adjacent pipeline of the faulty pipeline section and compare it with the allowable temperature difference. If the temperature difference of the adjacent pipeline is greater than the allowable temperature difference, it indicates that the temperature of the adjacent pipeline is greatly affected by the faulty pipeline. The system will continue to maintain the judgment of the faulty pipeline and notify the maintenance personnel to conduct inspections and maintenance. If the temperature difference of the adjacent pipeline is less than or equal to the allowable temperature difference, it indicates that the abnormal temperature of the faulty pipeline is caused by the abnormal temperature of the adjacent pipeline.In this case, the system will relabel the faulty pipeline as a controllable pipeline and implement an external cooling strategy for it to avoid greater impacts on the system operation due to problems with the faulty pipeline itself. Through this analysis and reaction mechanism, the system can intelligently determine the cause of the abnormal pipeline temperature and make adjustments according to the actual situation. This not only avoids unnecessary maintenance work caused by misjudgment but also ensures the stability and safety of the temperature control system and improves the overall operation efficiency. In this way, by analyzing the pipeline temperature difference, the problem of misjudgment caused by the temperature change of adjacent pipelines is solved. When a pipeline section is determined to be a faulty pipeline, the system does not immediately perform maintenance operations but further analyzes the temperature value of this pipeline section and the temperature difference between it and its adjacent pipelines. First, the system calculates the actual temperature difference of the pipeline by comparing the actual temperature difference of the faulty pipeline section with the operating temperature in the database. Combining the preset regulation value and adjustment coefficient, the system calculates the allowable temperature difference, which is used as the criterion for subsequent judgment. Next, the system compares the operating temperature difference between the adjacent pipelines of the faulty pipeline section with the allowable temperature difference. If the temperature difference between the adjacent pipelines is greater than the allowable temperature difference, the judgment of the faulty pipeline is maintained, and the maintenance personnel are notified for inspection. If the temperature difference between the adjacent pipelines is less than or equal to the allowable temperature difference, it indicates that the abnormal temperature of the faulty pipeline may be caused by the temperature problem of the adjacent pipelines. At this time, the system will relabel this pipeline as a controllable pipeline and start an external cooling strategy to adjust the pipeline temperature. Through this analysis mechanism, the system can effectively reduce misjudgment, avoid unnecessary maintenance work, and improve the accuracy, stability, and overall operation efficiency of the temperature control system.
[0028] In addition, in the present invention, it is described that the temperature anomaly of adjacent pipes may be affected by the temperature anomaly of the faulty pipe. Thus, when the temperature difference between the operating temperatures of adjacent pipes is less than or equal to the allowable temperature difference, it is determined that the adjacent pipes are greatly affected by the faulty pipe and no additional operations are performed on them. However, for the adjacent pipes on both sides of the faulty pipe, if they are truly only affected by the single faulty pipe, the temperature rise coefficients between the two adjacent pipes should not fluctuate much and should be relatively consistent. At this time, a reasonable fluctuation threshold is set to compare the adjacent pipes on both sides of the faulty pipe, so as to obtain the temperature difference between the adjacent pipes. By comparing the adjacent temperature difference with the reasonable fluctuation threshold, when the adjacent temperature difference is greater than the reasonable fluctuation threshold, it is determined that there are self-problems in addition to the influence of the faulty pipe in the two adjacent pipes, resulting in temperature anomalies. At this time, it is necessary to further compare the temperature difference data of the two adjacent pipes, mark the adjacent pipe with the higher temperature as the high-temperature pipe, and notify the maintenance personnel to repair the high-temperature pipe. If the adjacent temperature difference is less than or equal to the reasonable fluctuation threshold, it is determined that both adjacent pipes are only affected by the faulty pipe and no self-fault occurs, and no additional reaction is made. This method analyzes the temperature change conditions of the adjacent pipes on both sides of the faulty pipe, so as to effectively distinguish whether the adjacent pipes are only affected by the temperature of the faulty pipe or there are temperature anomalies in the adjacent pipes themselves. In this analysis, first, it is considered that the temperature change of the faulty pipe may affect the temperature of the adjacent pipes, resulting in the temperature difference between the adjacent pipes being equal to or smaller than the allowable temperature difference. In this case, it is determined that the temperature anomaly of the adjacent pipes is caused by the faulty pipe and no additional operations are required. However, if there are significant differences in the temperature changes of the adjacent pipes on both sides of the faulty pipe, and this difference exceeds a reasonable fluctuation threshold, then it can be judged that while the two adjacent pipes are affected by the faulty pipe, there may be other problems resulting in temperature anomalies. To further determine the cause of this temperature anomaly, the present invention proposes to compare the temperature differences between the adjacent pipes on both sides of the faulty pipe. If the adjacent temperature difference is greater than the reasonable fluctuation threshold, it means that while the two adjacent pipes are affected by the faulty pipe, there may be other factors causing temperature anomalies. In this case, the system will, through further analysis of the temperature difference data, mark the adjacent pipe with the higher temperature as the "high-temperature pipe" and promptly notify the maintenance personnel for inspection and repair. On the other hand, if the temperature difference between the adjacent pipes is less than or equal to the reasonable fluctuation threshold, it is considered that the adjacent pipes are only affected by the faulty pipe and there is no self-fault problem. At this time, the system no longer performs additional operations, avoiding misjudgment and unnecessary maintenance. By introducing a reasonable fluctuation threshold and analyzing the temperature differences of the adjacent pipes in detail, the present invention can more accurately distinguish the temperature anomaly of the faulty pipe from the temperature anomaly of the adjacent pipes themselves, thereby improving the accuracy of fault diagnosis, reducing misjudgment, and lowering the maintenance cost.This method can effectively ensure the safety and stability of the pipeline system while enhancing the intelligent level of maintenance management. In this way, by analyzing the temperature differences between adjacent pipelines on both sides of the faulty pipeline, it is effectively distinguished whether the adjacent pipelines are only affected by the faulty pipeline or have their own abnormal temperatures. By setting a reasonable fluctuation threshold, the system can accurately determine whether the temperature difference exceeds the expected fluctuation. If it exceeds, it is marked as a high-temperature pipeline and maintenance is notified. If it does not exceed, it is considered that the temperature anomaly is caused by the faulty pipeline, avoiding unnecessary operations. This method improves the accuracy of fault diagnosis, reduces misjudgment and maintenance costs, and ensures the stability and safety of the pipeline system.
[0029] The present invention provides a mold temperature control method for a mold temperature controller. This method includes the following steps: First step, establish a medium temperature control database, and monitor the mold temperatures in each pipeline in the mold temperature controller by configuring temperature sensors in each pipeline to obtain the temperature data of the molds in multiple pipelines; Second step, compare the uploaded temperature data with the corresponding required control temperature data of the molds in the database to obtain the temperature control difference between each section of the medium and the database medium, and compare the size of the temperature control difference with the regulation value, and make corresponding responses according to the comparison results; Third step, when the temperature control difference exceeds the regulation threshold, execute an external cooling strategy to make the temperature control difference reduce to within the adjustable threshold; Fourth step, continuously monitor whether the temperature control difference data changes after the temperature control difference can be reduced to within the adjustable threshold. When a change occurs, notify the maintenance personnel to check and maintain the pipeline. The purpose of the present invention is to design an advanced mold temperature control method to achieve efficient and precise management of the mold temperature, improve the stability of the production process and the consistency of product quality. By integrating modern sensing technology and intelligent control strategies, this method can monitor and dynamically adjust the temperatures of each pipeline inside the mold temperature controller in real time, ensuring that the temperature control system operates in the best state. The present invention introduces the setting of controllable thresholds and safety adjustment thresholds to further optimize the temperature adjustment process. By continuously monitoring the temperature difference changes of suspected abnormal pipelines, the system can dynamically adjust the control strategy. When the temperature difference returns to the controllable range and is higher than the controllable threshold, it is determined as an adjusted abnormal pipeline and the cooling process continues; if the temperature difference drops below the safety threshold, it is determined as a controllable pipeline and no further intervention is required. This mechanism not only improves the response speed of the temperature control system but also effectively avoids resource waste caused by over-regulation. In a multi-pipeline temperature control system, this method also analyzes the states of adjacent pipelines and preferentially processes pipelines with abnormal temperatures to ensure the temperature control stability of key areas. After cooling, the system will re-evaluate the state of the adjusted abnormal pipeline to determine whether it has become a controllable pipeline, thereby realizing the continuous optimization of the temperature control system.
