[0036] The present invention provides the following preferred embodiments:

[0037] Embodiment 1

[0038] In order to solve the problems of inaccurate temperature and pressure control and unsystematic process parameter setting in the traditional injection molding process control method, this embodiment proposes an injection molding process control method, such as Figure 1 As shown, the control method specifically includes the following steps:

[0039] S100, preheating the mold to an initial temperature by controlling the heating timing zone. The initial temperature is determined by the heating temperature on the control setting interface. The preheating time is timed by the heating timing zone. During the preheating process, the current of the heating point is monitored and adjusted in real time.

[0040] S200, keep the mold temperature stable for a certain period of time. The stable time is determined by the injection delay timer in the process display area.

[0041] S300, injecting the molten material into the mold by controlling the injection pressure and speed, the injection parameters are determined by the setting interface, and the injection pressure and speed are adjusted in real time.

[0042] S400, maintain the injection pressure holding time, the holding time is timed by the holding timer area, and the pressure change in the mold is monitored in real time during the holding process.

[0043] S500, maintain the mold cooling time, reduce the mold temperature to the set cooling temperature, the cooling time is timed by the cooling timing area, and the cooling medium flow is adjusted in real time.

[0044] S600, the mold opening action is controlled by the mold opening parameters to take out the finished product. The mold opening parameters are determined by the setting interface, and the mold stress changes during the mold opening process are monitored in real time.

[0045] Specifically, the mold is preheated to the initial temperature by controlling the heating timing zone. The initial temperature is determined by the heating temperature on the control setting interface, and the setting of the heating temperature can be based on the characteristics of different materials and the specific requirements of the mold. For example, for the injection molding of polymer materials, the initial temperature should be set above its melting temperature, but not too high to prevent material degradation. The preheating time is timed by the heating timing zone. During this process, the system monitors and adjusts the current of the heating point in real time to ensure that the temperature is evenly distributed in all parts of the mold. This process is achieved through the built-in temperature sensor, which feeds back the real-time temperature data to the control system. The system dynamically adjusts the heating power according to the preset heating curve to ensure that the mold temperature reaches the set value and remains stable.

[0046] Furthermore, the mold temperature is kept stable for a certain period of time, and the injection delay timer in the process display area is used. The role of the injection delay timer is to ensure that the mold can maintain a stable temperature level before starting injection molding to avoid temperature fluctuations affecting the filling effect of the molten material. The length of the stabilization time is adjusted according to the thermal stability of the specific material and the design characteristics of the mold, and generally takes from a few seconds to a few minutes.

[0047] Furthermore, during the injection stage, the molten material is injected into the mold by controlling the injection pressure and speed. The injection parameters are determined by the setting interface, and the injection pressure and speed are adjusted in real time. In order to ensure accurate control of the injection process, the system uses high-precision pressure sensors and speed sensors to monitor the pressure and speed changes during the injection process in real time to ensure that the parameters are within the set range. It should be understood that different materials have different viscosities and fluidities, and the settings of injection pressure and speed should also be adjusted accordingly to ensure that the material can fill the mold smoothly and avoid bubbles or uneven distribution.

[0048] Furthermore, during the holding stage, the holding time of the injection pressure is maintained by timing the holding timer. During the holding process, the system monitors the pressure changes in the mold in real time to ensure that the material is fully solidified in the mold to avoid shrinkage and deformation. The holding time is set according to the curing characteristics of the material and the design requirements of the product, usually between a few seconds and a few minutes. The pressure sensor in the mold feeds back the real-time pressure data to the control system, and the system dynamically adjusts the holding pressure based on this data to ensure the stability and consistency of the holding effect.

[0049] Furthermore, in the cooling stage, the mold temperature is lowered to the set cooling temperature by maintaining the mold cooling time. The cooling time is timed by the cooling timing area, and the cooling medium flow rate is adjusted in real time. During the cooling process, the system obtains the real-time temperature of the mold through the sensor and feeds this data back to the control system. According to the real-time temperature data, the system dynamically adjusts the flow rate and temperature of the cooling medium to ensure the uniformity and effectiveness of the cooling process. The cooling medium can be water, oil or other suitable coolants, which are optimized according to the material and cooling requirements of the mold.

[0050] Furthermore, during the mold opening stage, the mold opening action is controlled by the mold opening parameters to remove the finished product. The mold opening parameters are determined by the setting interface, and the mold stress changes during the mold opening process are monitored in real time. In order to avoid mold damage or finished product deformation during the mold opening process, the system will perform a series of pressure and temperature tests before mold opening to ensure that both the mold and the finished product are in the optimal state when the mold is opened. The mold opening action is controlled by a hydraulic or pneumatic system, and the parameter settings include mold opening speed, mold opening angle, etc., to ensure that the finished product can be removed smoothly and the mold is not damaged.

[0051] Furthermore, after the mold is opened, the mold is cleaned by gas treatment or mechanical cleaning to ensure the mold is clean. The gas treatment time is timed by the gas timing area, and the gas pressure and flow are monitored in real time during the mold cleaning process. In order to ensure that the mold can be kept clean after each injection cycle and prevent residues from affecting the next injection, the system uses high-pressure gas or special mold cleaning tools for cleaning. The gas pressure and flow are precisely controlled by the control system to ensure the cleaning effect.

[0052] After all steps are completed, the cycle ends. The cycle time is determined by the full timing and cycle parameters, and a process log is generated for subsequent analysis. The process log records the various parameters and operation time during the entire injection molding process, providing detailed data support for optimizing and improving the process. By analyzing these data, bottlenecks and problems in the process can be identified, and parameters can be adjusted in a targeted manner to improve production efficiency and product quality.

[0053] The benefit of this embodiment is that by precisely controlling the temperature and pressure of each link, real-time monitoring and dynamic adjustment of process parameters, the quality stability and production efficiency of the product are significantly improved. At the same time, the systematic process log recording and analysis function provides reliable data support for subsequent process optimization, realizing the refined and intelligent control of the injection molding process.

[0054] Embodiment 2

[0055] In order to solve the problem of unstable finished product quality caused by uneven temperature control during the mold preheating stage in the traditional injection molding process control process, this embodiment further optimizes the method of real-time monitoring and adjusting the heating point current during the mold preheating process.

[0056] like Figure 2 As shown, real-time monitoring and adjustment of the current at the heating point during the preheating process includes the following steps:

[0057] S101, monitoring the current temperature of the mold in real time through a temperature sensor;

[0058] S102, subtracting the set temperature from the current temperature to obtain the set temperature difference, then subtracting the average temperature from the current temperature to obtain the average temperature difference, respectively adding the adjustment coefficient to the set temperature difference and the average temperature difference, and then summing them to obtain the heating power.

[0059] S103, adjusting the heating power of the heating point according to the calculation result to maintain the set temperature, and monitoring the current change of each heating channel in real time.

[0060] S104. Dynamically adjust the heating power according to the current monitoring result, and trigger the alarm system when the current is abnormal.

[0061] The formula is as follows:

[0062] ;

[0063] Among them, Pheat is the heating power, Tset is the set temperature, Tcurrent is the current temperature, Tavg is the average temperature, C1 and C2 are adjustment coefficients, and C1 and C2 are adjusted through real-time feedback to keep the temperature stable during the preheating process.

[0064] Specifically, during the preheating process, the system monitors the current temperature of the mold in real time through multiple temperature sensors. The temperature sensor should be a high-precision, fast-response model, such as a Pt100 platinum resistance temperature sensor, to ensure the accuracy and timeliness of the temperature data. The temperature data of each heating point is collected through the control system and displayed in real time on the control interface.

[0065] Furthermore, in order to accurately control the mold temperature, the system adjusts the heating power of the heating point by calculating the set temperature difference and the average temperature difference. The set temperature difference is the difference between the set temperature and the current temperature, which reflects the degree of deviation of the current mold temperature from the target temperature. The average temperature difference is calculated by calculating the difference between the average temperature of all heating points of the mold and the current temperature to evaluate the uniformity of the temperature of the entire mold. The set temperature difference and the average temperature difference are added with the adjustment coefficient and then summed to obtain the heating power. The adjustment coefficient can be determined based on empirical data or through experimental optimization to ensure the sensitivity and stability of temperature regulation.

[0066] Furthermore, based on the above calculation results, the system dynamically adjusts the heating power of each heating point to maintain the set temperature. The adjustment of the heating power is achieved through the PID control algorithm, which can dynamically adjust the heating current according to the temperature error to ensure that the temperature quickly reaches the set value and remains stable. It should be understood that the parameter setting of the PID control algorithm is crucial to the control effect, and the selection of parameters needs to be debugged and optimized in combination with specific process requirements.

[0067] Furthermore, during the heating process, the system monitors the current changes of each heating channel in real time. The current sensor should be a high-precision model, such as a Hall effect current sensor, which can reflect the current changes of the heating channel in real time. Real-time current data is also displayed on the control interface, and the operator can view and adjust the heating parameters at any time.

[0068] Furthermore, based on the current monitoring results, the system dynamically adjusts the heating power to ensure that the heating effect of each heating point is consistent. When the current of a certain heating point is abnormal, such as too high or too low, the system will immediately trigger the alarm system to remind the operator to check and handle it. The alarm system includes an audible and visual alarm device and interface prompt information to ensure that abnormal situations can be discovered and handled in time to avoid damage to the mold and product.

[0069] Furthermore, in order to improve the stability and reliability of the system, the current function of real-time monitoring and adjusting the heating point during the preheating process can be combined with the thermodynamic model of the mold to optimize the heating control strategy through the analysis of historical data and current process parameters. For example, the system can pre-set different heating strategies according to the thermal conductivity and specific heat capacity of different mold structures and materials to ensure a more uniform temperature distribution during the heating process.

[0070] In addition, in this embodiment, the heating power adjustment of each heating point can be compared and optimized with the temperature distribution data of each area in the mold to ensure the temperature uniformity of each area of ​​the mold. By comparing the real-time temperature of each heating point with the set temperature, the system can automatically adjust the heating power of the heating point to avoid local overheating or overcooling.

[0071] The benefit of this embodiment is that by real-time monitoring and dynamic adjustment of the current of the heating point, the temperature uniformity and stability of the mold during the preheating process are ensured, effectively improving the quality of the finished product and production efficiency. Through the application of high-precision temperature sensors and current sensors, combined with PID control algorithms and alarm systems, precise control of the heating process of the heating point is achieved, significantly improving the automation and intelligence level of the injection molding process. Through the analysis and optimization of historical data, the system can continuously adjust and improve the heating control strategy to ensure the best effect of the mold preheating process.

[0072] It should be understood that this embodiment is not only applicable to traditional polymer material injection molding, but can also be extended to other injection molding processes that require precise temperature control, such as metal powder injection molding (MIM) and ceramic injection molding (CIM), etc., providing a universal temperature control solution for different materials and processes. Through this embodiment, the temperature control accuracy and stability of the injection molding process have been significantly improved, further improving production efficiency and product quality, and providing strong support for the intelligent development of the injection molding industry.

[0073] Embodiment 3

[0074] In order to solve the problems of inconsistent product quality and low process efficiency caused by unstable injection pressure and speed control in traditional injection molding process, such as Figure 3 As shown, this embodiment further refines the method for controlling pressure and speed during the injection molding process, and specifically includes the following steps:

[0075] S301, input the parameters of injection pressure and speed through the setting interface.

[0076] S302, start the injection molding machine and inject the molten material into the mold.

[0077] S303, monitor the changes of pressure and speed in the injection molding process in real time through sensors.

[0078] S304. Dynamically adjust the parameters of injection pressure and speed according to the monitoring results.

[0079] Specifically, first enter the injection pressure and speed parameters through the setting interface. The setting interface is intuitive and easy to use, and the operator can flexibly set the injection pressure and speed parameters according to the requirements of different materials and molds. The selection of injection pressure and speed parameters needs to be combined with the rheological properties of the specific material and the structural characteristics of the mold. For example, for polymer materials with good fluidity, a higher injection speed can be set, while for materials with higher viscosity, a lower injection speed is required to avoid uneven filling.

[0080] Further, the injection molding machine is started to inject the molten material into the mold. The injection molding machine should be a model with high-precision control and fast response capabilities, such as a fully electric injection molding machine, which has excellent control accuracy and stability. After starting, the injection molding machine begins to inject the molten material into the mold according to the preset injection pressure and speed parameters. At this time, the changes in pressure and speed during the injection molding process are monitored in real time through the built-in high-precision pressure sensor and speed sensor.

[0081] It is important to understand that real-time monitoring of pressure and speed during the injection molding process is critical. High-precision sensors can accurately capture instantaneous data changes and feed them back to the control system. The control system uses advanced control algorithms such as PID control and fuzzy control to adjust the working parameters of the injection molding machine in real time to ensure the stability and consistency of the injection molding process.

[0082] Furthermore, based on the monitoring results, the system dynamically adjusts the parameters of injection pressure and speed. For example, during the injection process, if the sensor detects that the pressure or speed deviates from the preset value, the control system will immediately adjust the working state of the injection molding machine to correct the parameter deviation. The dynamic adjustment process is real-time and continuous, ensuring that the parameters of the entire injection process are always maintained within the optimal range.

[0083] Furthermore, in order to improve the control accuracy and response speed, this embodiment adopts an adaptive control algorithm. The adaptive control algorithm can automatically adjust the control parameters according to the real-time monitoring data and historical data to adapt to the changes of different materials and process conditions. For example, during the production process, due to differences in material batches or changes in ambient temperature, the injection molding parameters may need to be adjusted. The adaptive control algorithm can automatically identify these changes and adjust the injection molding pressure and speed to ensure the stability of the production process and the consistency of product quality.

[0084] This embodiment also introduces predictive control technology. By analyzing and modeling historical data, the system predicts possible parameter changes in the future injection molding process and adjusts the control strategy in advance. For example, by analyzing the historical change trends of temperature, pressure and speed, the system can predict the parameter fluctuations that may occur at a certain moment and make adjustments in advance to avoid process fluctuations caused by sudden changes.

[0085] In addition, in this embodiment, the monitoring data and adjustment records of the injection molding process are saved in real time to the database to form a detailed process log. The process log records all key parameters and adjustments in each injection molding process, providing valuable data support for subsequent process optimization and problem analysis. By analyzing the process log, potential problems in the production process can be discovered and solved, further improving the stability of the process and product quality.

[0086] Through the implementation of this embodiment, the control accuracy and stability of pressure and speed during the injection molding process have been significantly improved, the consistency of product quality has been significantly improved, and the production efficiency has been greatly improved. At the same time, the introduction of adaptive control and predictive control technology enables the system to intelligently respond to various uncertainties in the production process and ensure the continuity and stability of the production process. This embodiment provides strong support for the intelligent and refined control of the injection molding process, and promotes the development of the injection molding industry towards efficient, stable and high-quality production.

[0087] Embodiment 4

[0088] In order to solve the problem of product defects and low production efficiency caused by inaccurate pressure holding time control in the traditional injection molding process, this embodiment further optimizes the pressure holding time control method in the injection molding process, such as Figure 4 As shown, the specific steps include:

[0089] S401. Input and confirm the required holding pressure parameters through the control setting interface, and adjust them according to different mold and material types.

[0090] S402. In the control setting interface, set the pressure holding time.

[0091] S403. In the automatic process, when the injection molding step is completed, the system automatically enters the pressure holding state. In the manual mode, the pressure holding operation is started through the manual interface.

[0092] S404. The pressure change in the mold during the pressure holding process is monitored in real time through the pressure sensor built into the mold, and the pressure monitoring data is displayed in the mold temperature status display area of ​​the main interface.

[0093] S405: During the pressure holding process, the temperature change of the mold is continuously monitored, the mold temperature is kept within the set range, and the temperature data is displayed in real time in the mold temperature status display area.

[0094] S406. Dynamically adjust the holding pressure according to the real-time monitored pressure data. In manual mode, manually adjust the holding time according to the upper limit of the cooling time in the system settings.

[0095] S407. When the holding time reaches the preset value, the system automatically ends the holding operation and enters the cooling step. The process status display area of ​​the main interface will display the final duration of the holding time. In manual mode, the holding operation is manually ended through the manual interface.

[0096] Specifically, first input and confirm the required holding pressure parameters through the control setting interface. The setting of holding pressure parameters should be adjusted based on different molds and material types. For example, for high-viscosity materials, a higher holding pressure is required to ensure uniform filling in the mold, while for low-viscosity materials, the holding pressure can be appropriately reduced. The control setting interface provides precise parameter input options, and operators can flexibly adjust the holding pressure according to specific process requirements.

[0097] Furthermore, in the control setting interface, set the holding time. The length of the holding time has an important impact on the molding quality of the product, and is usually set according to the curing time of the material and the design characteristics of the mold. The system allows the operator to accurately input the holding time on the interface and dynamically adjust it according to different process requirements.

[0098] Furthermore, in the automatic process, when the injection molding step is completed, the system automatically enters the pressure holding state. In manual mode, the operator can start the pressure holding operation through the manual interface. The pressure holding operation in the automatic process is controlled by the system preset program to ensure the consistency and stability of the pressure holding process; while in manual mode, the operator can manually start the pressure holding according to the real-time situation to deal with special process requirements or emergencies.

[0099] Furthermore, during the pressure holding process, the pressure changes in the mold are monitored in real time through the high-precision pressure sensor built into the mold. The pressure sensor should be a fast-response, high-precision model, such as a piezoelectric pressure sensor, which can accurately reflect the dynamic changes in pressure during the pressure holding process. The pressure monitoring data is transmitted in real time to the mold temperature status display area of ​​the main interface, and the operator can view and adjust it at any time.

[0100] Furthermore, the temperature changes of the mold are continuously monitored during the holding process. Temperature monitoring is also achieved by the built-in high-precision temperature sensor, which collects the temperature data of the mold in real time and feeds this data back to the control system. The system dynamically adjusts the holding temperature in the mold according to the temperature monitoring data to ensure that the temperature remains within the set range. The temperature data is displayed in real time in the mold temperature status display area, and the operator can view and adjust it at any time.

[0101] Furthermore, the system dynamically adjusts the holding pressure based on the real-time monitored pressure data. In automatic mode, the system automatically adjusts the holding pressure through the control algorithm to keep the pressure stable. In manual mode, the operator can manually adjust the holding time through the cooling time limit in the system settings to meet special process requirements. For example, when the curing time of the material in the mold is long, the holding time can be manually extended to ensure that the material is fully cured.

[0102] Furthermore, when the holding time reaches the preset value, the system automatically ends the holding operation and enters the cooling step. The start and end time of the cooling step will be displayed in the process status display area of ​​the main interface, and the final duration of the holding time will also be recorded in the display area. In manual mode, the operator can manually end the holding operation through the manual interface to ensure flexible response to different production needs.

[0103] Furthermore, this embodiment can also introduce intelligent analysis and feedback mechanisms. The system will record all parameters and monitoring data of each pressure holding operation to form a detailed process log. By analyzing these data, possible problems in the pressure holding process can be identified, such as excessive pressure fluctuations or unstable temperature control, and targeted adjustments and optimizations can be made. The analysis results of the process log can be used to improve the pressure holding strategy, improve production efficiency and product quality.

[0104] In addition, in order to ensure the stability and reliability of the pressure-holding process, this embodiment also designs a fault detection and alarm system. When an abnormal situation occurs during the pressure-holding process, such as a failure of the pressure sensor or a temperature exceeding the set range, the system will immediately trigger an alarm to remind the operator to check and handle it. The alarm system includes an audible and visual alarm device and interface prompt information to ensure that abnormal situations can be discovered and handled in a timely manner.

[0105] Through the implementation of this embodiment, the control accuracy and stability of the holding time during the injection molding process have been significantly improved. Through intelligent analysis and feedback mechanisms, the system can continuously optimize the holding strategy, adapt to changes in different materials and process conditions, and ensure the continuity and stability of the production process. This embodiment provides strong support for the intelligent and refined control of the injection molding process, and promotes the development of the injection molding industry towards efficient, stable and high-quality production.

[0106] Embodiment 5

[0107] In order to solve the problems of low production efficiency and unstable product quality caused by inaccurate mold cooling time in the traditional injection molding process, this embodiment further refines the method of maintaining the mold cooling time, such as Figure 5 As shown, the specific implementation is as follows:

[0108] S501, obtain the real-time temperature of the mold through the sensor and feed it back to the control system.

[0109] S502. Dynamically adjust the flow rate and temperature of the cooling medium according to the real-time temperature feedback.

[0110] S503: Optimize cooling parameters to improve cooling efficiency based on historical cooling data.

[0111] S504, monitor the flow rate of the cooling medium in real time and dynamically adjust the flow rate and temperature of the cooling medium according to the real-time temperature.

[0112] S505, when the duration of the cooling step exceeds the upper limit of the cooling time, the current cooling step is automatically ended and the step of taking out the finished product by controlling the mold opening action through the mold opening parameters is entered.

[0113] Specifically, the real-time temperature of the mold is first obtained through the sensor and fed back to the control system. Temperature sensing should use high-precision infrared temperature sensors or embedded thermocouples, which can quickly and accurately capture the temperature changes on the surface and inside of the mold. Real-time temperature data is quickly transmitted to the control system through the data transmission module to ensure the immediacy and accuracy of temperature monitoring.

[0114] Furthermore, the flow and temperature of the cooling medium are dynamically adjusted according to the real-time temperature feedback. The cooling medium is usually cooling water or cooling oil, and its flow and temperature are adjusted by electric valves and thermostats. The system's built-in PID control algorithm can automatically adjust the flow and temperature of the cooling medium according to the temperature feedback data to achieve rapid cooling and maintain stable mold temperature. It should be understood that the precise control of the temperature and flow of the cooling medium directly affects the efficiency of mold cooling and the final quality of the product.

[0115] In order to further improve the cooling efficiency, the cooling parameters are optimized according to the historical cooling data. The system will record all relevant data during each cooling process, including the flow rate, temperature of the cooling medium and the temperature change of the mold. By analyzing these historical data, the parameter settings during the cooling process are optimized. For example, in the cooling process of certain materials, the flow rate and temperature curve of the cooling medium can be adjusted to find the best cooling path, shorten the cooling time and improve production efficiency.

[0116] Furthermore, the flow rate of the cooling medium is monitored in real time and the flow rate and temperature of the cooling medium are dynamically adjusted according to the real-time temperature. In this step, the system not only monitors the temperature change of the mold, but also needs to monitor the flow rate of the cooling medium in real time. The flow sensor can be a turbine flowmeter or an electromagnetic flowmeter, which can provide high-precision flow measurement data. The control system adjusts the flow rate and temperature of the cooling medium in real time according to the data fed back by the flow sensor and the temperature change of the mold to ensure the efficiency and stability of the cooling process.

[0117] Furthermore, when the duration of the cooling step exceeds the upper limit of the cooling time, the system automatically ends the current cooling step and enters the step of taking out the finished product by controlling the mold opening action through the mold opening parameters. The upper limit of the cooling time is preset by the system to ensure that the cooling process is not too long or too short based on the characteristics of different materials and molds. The system automatically monitors the cooling time, and when the time reaches the preset upper limit, it automatically ends the cooling and triggers the mold opening step. The parameters of the mold opening step can also be set through the control interface, including the mold opening speed and mold opening force, to ensure that the process of taking out the finished product is smooth and does not damage the mold and the product.

[0118] Furthermore, intelligent cooling control technology is introduced in this embodiment. Through comprehensive analysis of real-time and historical data, the system can predict potential problems in the cooling process and make adjustments in advance. For example, when the system detects that the cooling efficiency has decreased over a period of time, which may be due to the excessive temperature or insufficient flow of the cooling medium, the system will automatically increase the flow of the cooling medium or reduce its temperature to ensure that the cooling process continues to be efficient.

[0119] In addition, this embodiment also takes into account the needs of energy saving and environmental protection. By optimizing the usage and temperature control of the cooling medium, energy consumption and waste of the cooling medium can be effectively reduced. For example, through the intelligent control system, when the mold temperature is close to the set value, the flow rate of the cooling medium is gradually reduced to avoid energy waste caused by excessive cooling. The system can also select an appropriate cooling medium circulation method according to process requirements to further improve energy utilization efficiency.

[0120] Through the implementation of this embodiment, the control accuracy and efficiency of the mold cooling time have been significantly improved. The method of real-time temperature monitoring and dynamic adjustment of cooling parameters ensures the stability and consistency of the mold cooling process, and improves production efficiency and product quality. At the same time, through intelligent analysis and historical data optimization, the system can continuously adjust and improve the cooling strategy to adapt to changes in different materials and process conditions. By optimizing energy utilization, this embodiment not only improves process efficiency, but also meets the requirements of energy conservation and environmental protection, and provides reliable technical support for the sustainable development of injection molding technology.

[0121] The benefit of this embodiment is that by accurately controlling the mold cooling time and various parameters during the cooling process, the production efficiency and consistency of product quality are significantly improved. The introduction of intelligent control technology and energy-saving measures makes the injection molding process more efficient, stable and environmentally friendly, providing strong technical support for the development of the injection molding industry.

[0123] In order to solve the inaccuracy problem existing in the traditional cooling time calculation, the present embodiment further optimizes the cooling time calculation method, and calculates the cooling time in a more scientific and systematic way to improve the accuracy and stability of the process.

[0124] like Figure 6 As shown, the calculation method of the cooling time includes the following steps:

[0125] S5011. Set a preset cooling time.

[0126] S5012. Subtract the mold temperature from the ambient temperature and then multiply it by the heat capacity of the mold to obtain the thermal tolerance.

[0127] S5013. Multiply the thermal conductivity of the mold by the cooling area to obtain a cooling coefficient.

[0128] S5014. Subtract the preset cooling time from the ratio of the thermal tolerance and the cooling coefficient to obtain the cooling time.

[0129] The calculation formula for the cooling time is as follows:

[0130] ;

[0131] Among them, Tcool represents the cooling time, Tset represents the set cooling time, Cmold represents the heat capacity of the mold, Tmold represents the mold temperature, Tenv represents the ambient temperature, k represents the thermal conductivity, and A represents the cooling area.

[0132] Specifically, the preset cooling time is first set. The preset cooling time is usually based on empirical values ​​or preliminary test data as the starting point for calculation. In practice, the setting of this time needs to be combined with specific material properties and mold design. For example, mold materials with high heat capacity and complex mold structures may require a longer preset cooling time.

[0133] Furthermore, the mold temperature is subtracted from the ambient temperature and then multiplied by the heat capacity of the mold to obtain the thermal tolerance. The mold temperature is generally measured in real time by a high-precision temperature sensor, while the ambient temperature can be obtained by the workshop ambient temperature sensor. The heat capacity Cmold of the mold is a material characteristic parameter, which is usually calculated by the specific heat capacity of the specific material and the mold mass. It should be understood that the thermal tolerance reflects the amount of heat that the mold needs to release during the cooling process, which directly affects the calculation of the cooling time.

[0134] Furthermore, the thermal conductivity of the mold is multiplied by the cooling area to obtain the cooling coefficient. The thermal conductivity λ of the mold is a material characteristic parameter, and the cooling area A is the actual surface area of ​​the mold in contact with the cooling medium. It can be understood that the larger the cooling coefficient, the higher the heat conduction efficiency of the mold, which can release heat faster and shorten the cooling time.

[0135] Furthermore, the cooling time is finally obtained according to the ratio of the preset cooling time, thermal tolerance and cooling coefficient. The accuracy and applicability of this calculation model are ensured through dual verification of actual working conditions on site and historical data.

[0136] Furthermore, a dynamic adjustment mechanism can be introduced into the calculation method of cooling time. The system records the actual cooling time and mold temperature changes during each cooling process and establishes a dynamic adjustment model for cooling time. Through machine learning algorithms, the system can continuously optimize the calculation parameters of cooling time and improve calculation accuracy. For example, when the system detects that the actual cooling time deviates greatly from the preset cooling time, it will automatically adjust the preset cooling time and the parameters in the calculation formula to reduce the deviation.

[0137] The benefit of this embodiment is that the calculation accuracy and process stability of the cooling time are significantly improved through scientific calculation methods and dynamic adjustment mechanisms. The optimized calculation method is not only applicable to common injection molding materials and molds, but can also be adaptively adjusted according to different materials and process conditions to ensure the best cooling effect in various production environments. Through precise calculation and real-time optimization, the energy efficiency of the cooling process is maximized, further improving production efficiency and product quality consistency, and providing strong support for the intelligent and refined control of the injection molding industry.

[0138] Embodiment 7

[0139] In order to solve the problem of uneven temperature distribution caused by inaccurate control of heating points in traditional injection molding processes, this embodiment further refines the control and monitoring method for each heating point, that is, each heating point has an on and off function and can display the real-time current value of each heating point.

[0140] Specifically, each heating point is equipped with an independent control switch, which can be precisely operated through the control interface. The control switch of each heating point should use a high-precision electronic switch, such as SSR (solid-state relay), which has a fast response speed and strong durability, and can achieve rapid opening and closing of the heating point. Such a design can ensure that the temperature control of each heating area is optimal during the complex injection molding process.

[0141] Furthermore, by integrating a current sensor at each heating point, the current value of each heating point is monitored and displayed in real time. The current sensor should be a high-precision Hall sensor or other sensor suitable for high current measurement, which can accurately reflect the actual current situation of the heating point. The current data is transmitted to the system in real time and visualized in the status display area of ​​each heating point on the main control interface. This real-time monitoring mechanism can help operators quickly identify abnormal conditions in the operation of the heating point, such as excessive current or open circuit, and make timely adjustments and maintenance to avoid product quality problems caused by improper temperature control.

[0142] It is important to understand that real-time current monitoring is not only helpful for troubleshooting, but also has important significance for optimizing energy management. Through the analysis of current data, the energy consumption of each heating point can be evaluated, and the opening and closing strategies of the heating points can be optimized accordingly. For example, in the actual production process, some heating points may not need to work for a long time. Through current data analysis, their working cycle can be adjusted, thereby saving energy and improving overall production efficiency.

[0143] Through this embodiment, the independent control and real-time current monitoring functions of each heating point are realized, which significantly improves the temperature control accuracy and stability of the injection molding process. Accurate heating point control can not only improve the molding quality of the product, but also optimize energy consumption and reduce production costs through intelligent management. Through this embodiment, the intelligence and refinement level of the injection molding process is further improved, providing a strong guarantee for high-quality and efficient production.

[0144] Embodiment 8

[0145] In order to solve the problem of uneven temperature control caused by inaccurate temperature measurement in the traditional injection molding process, this embodiment further optimizes the method for obtaining the average temperature, such as Figure 7 As shown, the specific implementation is as follows:

[0146] S1021. Measure the temperature of each heating point.

[0147] S1022, summing up the temperature of each heating point.

[0148] S1023. Compare the sum of the temperatures of each heating point with the number of heating points to obtain an average temperature.

[0149] The average temperature is calculated as follows:

[0150] ;

[0151] Wherein, Ti is the temperature of the i-th heating point, and n is the number of heating points.

[0152] Specifically, the temperature of each heating point is measured first. To ensure the accuracy and reliability of the measurement, the temperature sensor should be a high-precision thermocouple or infrared temperature sensor, which can respond quickly and accurately capture the real-time temperature data of each heating point. The temperature data of each heating point is transmitted to the control system through the data acquisition system to ensure the real-time synchronization of temperature data between different heating points.

[0153] Furthermore, the temperature of each heating point is accumulated and summed. The temperature values ​​of each heating point are accumulated in real time through the data acquisition system, and this process can be implemented by programming in the control system. It should be understood that the real-time and accuracy of data transmission must be guaranteed during the accumulation and summation process to avoid inaccurate temperature accumulation values ​​due to data delays or transmission errors.

[0154] Furthermore, the accumulated total is divided by the number of heating points to obtain the average temperature of each heating point. The system's built-in algorithm can automatically complete this calculation and display the result on the control interface.

[0155] It is important to understand that real-time acquisition of average temperature is very important for temperature field control in the injection molding process. If an abnormal temperature deviation occurs at a certain heating point, it can be discovered and adjusted in time through the change in average temperature. In addition, by real-time monitoring and calculating the average temperature, product quality problems caused by local over-high or over-low temperatures can be effectively avoided.

[0156] Furthermore, this embodiment also introduces an intelligent analysis and early warning mechanism for temperature data. By monitoring the temperature change data of each heating point for a long time, the system can establish a historical model of temperature change and a normal fluctuation range. When the actual measured temperature data fluctuates abnormally or deviates from the normal range, the system will automatically trigger the early warning mechanism and prompt the operator to perform inspection and maintenance. This intelligent early warning mechanism can effectively improve the reliability of the production process and the stability of product quality.

[0157] Through this embodiment, the method for obtaining the average temperature has been optimized and refined, significantly improving the accuracy and stability of temperature control. The use of high-precision temperature sensors and real-time data acquisition systems ensures that the temperature data of each heating point is accurate; the introduction of intelligent analysis and early warning mechanisms improves the reliability of the production process. Through efficient and accurate temperature monitoring and control, it provides strong technical support for the optimization of the injection molding process and lays a solid foundation for further improving product quality and production efficiency.

[0209] This embodiment provides a non-volatile computer-readable storage medium, in which a computer program of the injection molding process control method is stored, so as to achieve efficient control of the device during operation.

[0210] Specifically, the computer program involved in this embodiment integrates the calculation method of parameters such as preset cooling time, thermal tolerance and cooling coefficient. The preset cooling time is set by the program, the mold temperature and ambient temperature are obtained in real time, and the thermal tolerance and cooling coefficient are calculated, and the cooling time is finally determined. The program adopts an efficient algorithm to ensure the real-time and accuracy of the calculation.

[0211] Furthermore, the program includes independent control functions for each heating point. The opening and closing of each heating point is controlled by the program through an electronic switch, and its current value is monitored in real time. It should be understood that the program can collect and display the current data of each heating point, and conduct abnormal current warning to ensure the stability of the production process.

[0212] Furthermore, the program also includes a step for obtaining the average temperature. By measuring the temperature of each heating point in real time, accumulating and summing it, and calculating the average value, the program ensures the accuracy of temperature control.
