[0020] Based on the above steps, the detailed process is as follows: Step S1: Obtain the three-dimensional data and injection molding process parameters of the automobile instrument panel injection mold. The three-dimensional data describes the geometric shape and size of the mold in detail. The injection molding process parameters include various specific data required in the injection molding process, such as temperature, pressure, speed, etc.

[0032] For example, the selected solution B specifically includes: mold temperature: 176.5°C, injection pressure: 73MPa, holding time: 5.5 seconds, production cycle: 28 seconds per piece, and mold maintenance cycle: every 8,000 injection cycles.

[0033] The present invention provides a control method for an automobile parts injection mold. By acquiring the three-dimensional data and injection molding process parameters of the automobile instrument panel injection mold and constructing the instrument panel mold structure based on these parameters, the structural characteristics and process requirements of the mold can be more accurately evaluated, and reliable basic data can be provided for subsequent control and optimization. By acquiring the mold operation data in real time and associating it with the mold structure, real-time monitoring and analysis of the mold state are realized, which helps to timely discover and solve problems in the production process and improve the stability and reliability of production. The performance of the mold structure is predicted based on the injection molding data, and potential performance problems can be identified in advance, providing guidance for the maintenance and optimization of the mold, thereby improving the service life and production efficiency of the mold. By comprehensively analyzing the real-time mold state information and mold performance information, an initial mold control plan is formulated, and refined management of mold operation is realized, which helps to improve product quality and production efficiency. The injection molding data is parameter-identified and adaptively adjusted based on the mold performance information, so that the control method can flexibly respond to the production requirements of instrument panels of different materials and shapes, and improves the adaptability and flexibility of mold control.

[0034] In one embodiment, the three-dimensional data is structured based on the injection molding process parameters to obtain the instrument panel mold structure, including: The three-dimensional data of the instrument panel is meshed to generate a mesh model composed of triangular or quadrilateral units. The density and quality of the mesh directly affect the accuracy of subsequent analysis, so it is necessary to reasonably set the mesh parameters according to the structural characteristics of the instrument panel.

[0035] The characteristics of the injection molding process parameters are extracted to obtain melt flow characteristic data, molding temperature data and pressure parameters. The injection molding process parameters include material characteristics, injection speed, holding time, etc. These injection molding process parameters are simulated and calculated to obtain the flow characteristic data such as the flow path and velocity distribution of the melt in the mold cavity, as well as the temperature change data and pressure distribution data of each part during the molding process.

[0036] The mold cavity and gate structure of the initial mesh model are constructed based on the melt flow characteristic data to obtain the mold basic structure. According to the melt flow characteristic data, the location, size and number of the gate are determined, and the layout of the runner system is designed. The cavity structure is optimized according to the flow path, such as adding guide grooves, etc., to ensure that the melt can evenly fill the cavity. In this way, the mold basic structure including the cavity, gate and runner system is obtained.

[0037] According to the molding temperature data and pressure parameters, the mold base structure is thermodynamically analyzed to obtain the thermal stress distribution data. The molding temperature data and pressure parameters are imported into the finite element analysis software to perform transient thermal analysis and structural stress analysis on the mold base structure. The temperature field distribution and stress field distribution of each part of the mold during the injection molding process are calculated to determine the hot spot area and stress concentration area of ​​the mold.

[0038] Based on the thermal stress distribution data, the mold base structure is optimized to obtain the dashboard mold structure. For hot spots, the design of the cooling system is optimized, such as adjusting the position and size of the cooling water channel; for stress concentration areas, local reinforcement is performed by adding ribs and adjusting structural transitions. At the same time, considering the opening and closing, ejection and other functional requirements of the mold, the parting surface, ejection system and other structures are designed. After multiple rounds of iterative optimization, the dashboard mold structure that meets various performance requirements is finally obtained.

[0039] This embodiment provides an accurate data basis for mold structure design by meshing three-dimensional data and extracting the characteristics of injection molding process parameters, effectively improving the accuracy and reliability of mold design. The mold cavity and gate structure are constructed based on the melt flow characteristic data to ensure a high degree of match between the mold structure and the injection molding process, which is beneficial to improving the molding quality of the product. Thermodynamic analysis based on molding temperature data and pressure parameters can accurately identify the hot spots and stress concentration areas of the mold, providing a clear direction for subsequent structural optimization. Through multiple rounds of iterative optimization of the mold basic structure, the final dashboard mold structure is more perfect in performance and function, greatly reducing the problems that may occur during the actual mold trial.

[0040] In one embodiment, real-time operation data of an automobile dashboard injection mold is obtained, and the real-time operation data is associated with the dashboard mold structure to obtain corresponding real-time mold status information, including: Data collection is performed on the injection mold of the automobile instrument panel, and the collected data includes mold temperature data, mold pressure data, mold displacement data and mold vibration data. Temperature data is collected through thermocouples or infrared sensors, pressure data is collected through pressure sensors, displacement data is collected through displacement sensors, and vibration data is collected through acceleration sensors. These data reflect the various physical state changes of the mold during the injection molding process.

[0041] The collected mold temperature data is mapped to the dashboard mold structure, and a heat flow analysis is performed to obtain the temperature gradient distribution of each part of the mold. The heat flow analysis uses the finite element method to discretize the mold structure into grid units, calculate the temperature change rate of each unit, and thus obtain the temperature gradient distribution of the entire mold. This step helps to identify hot spots and uneven temperature distribution in the mold.

[0042] The mold pressure data is correlated with the stress-bearing parts in the instrument panel mold structure to obtain the pressure spectrum characteristics. The correlation analysis combines the pressure data with the geometric information of the mold structure to identify the key parts that bear greater pressure. The pressure data of these parts are Fourier transformed to obtain the pressure spectrum, and the main frequency components are extracted as the pressure spectrum characteristics. This step helps to find the stress concentration areas and periodic pressure changes in the mold.

[0043] Based on the mold displacement data, the instrument panel mold structure is subjected to geometric deviation analysis to obtain the mold deformation. Geometric deviation analysis calculates the deformation in three-dimensional space by comparing the difference between the actual position of the mold and the ideal position. The deformation includes displacement components in the x, y, and z directions, which are the three-dimensional directions of length, width, and height, respectively, and reflect the degree of deformation of the mold during the injection molding process.

[0044] The vibration data is correlated with the connection points in the dashboard mold structure to obtain the vibration feature vector. The correlation calculation combines the vibration data with the location information of the connection points in the mold structure to identify the key connection points with large vibrations. The vibration data of these connection points is analyzed by principal component analysis to extract the main vibration components as vibration feature vectors. This step helps to find loose or unstable connections in the mold.

[0045] Based on the dashboard mold structure, the temperature gradient distribution, pressure spectrum characteristics, mold deformation and vibration feature vector are fused to obtain a comprehensive mold state matrix. The multi-source data fusion process is as follows: First, the dashboard mold structure is divided into several structural sub-areas, each of which corresponds to a row of the comprehensive mold state matrix. The division of each structural sub-area is based on the geometric characteristics and functional partitions of the mold to ensure that the status of each part of the mold can be fully reflected.

[0046] For each structural sub-region, the temperature gradient value of the temperature gradient distribution, the main frequency component of the pressure spectrum, the three-dimensional directional component of the mold deformation and the main vibration component of the vibration eigenvector are extracted. These extracted eigenvalues ​​constitute the regional eigenvector of the structural sub-region. In the regional eigenvector, the temperature gradient value reflects the severity of the temperature change in the region, the main frequency component of the pressure spectrum indicates the main periodic pressure borne by the region, the three-dimensional directional component of the deformation describes the deformation of the region, and the main vibration component reflects the vibration characteristics of the region.

[0047] The temperature gradient value, main frequency component, three-dimensional direction component and main vibration component are arranged in a predefined order to form the regional feature vector of each structural sub-region. The predefined order is usually: temperature gradient value, pressure frequency component, x-direction deformation, y-direction deformation, z-direction deformation, and main vibration component. This arrangement order ensures the orderly organization of different types of data.

[0048] The regional feature vectors of all structural sub-regions are combined to form a comprehensive mold state matrix. In this matrix, each row represents a structural sub-region, and each column represents each regional feature vector. Such a matrix structure enables the overall state information of the mold to be systematically and structured.

[0049] The state recognition of the comprehensive mold state matrix is ​​performed to obtain the corresponding mold state information. The state recognition adopts machine learning algorithms, such as support vector machines or neural networks, which take the comprehensive mold state matrix as input and output various mold state categories, such as normal, slightly abnormal, and seriously abnormal.

[0050] The mold status information is evaluated in real time according to the preset status evaluation index system to obtain real-time mold status information. The status evaluation index system includes evaluation standards in multiple dimensions such as temperature uniformity, pressure stability, deformation degree, vibration intensity, etc. By comparing the mold status information with these standards, a quantitative evaluation result of the current state of the mold is given to form real-time mold status information.

[0051] This embodiment realizes comprehensive and real-time monitoring of the mold status by collecting and fusion analyzing multi-source data of the automobile dashboard injection mold. This method can not only capture the changes in the temperature, pressure, displacement and vibration of the mold, but also associate these data with the mold structure to obtain more accurate and meaningful status information. By dividing the mold structure into sub-areas and constructing a comprehensive mold status matrix, the complex mold status information is systematically and structured, which is convenient for subsequent status identification and evaluation. This multi-dimensional and multi-scale status monitoring method greatly improves the accuracy and comprehensiveness of mold status evaluation and provides a reliable basis for precise control and preventive maintenance of the mold.

[0052] In one embodiment, the injection molding data of the automobile instrument panel injection mold is obtained, and the performance of the instrument panel mold structure is predicted based on the injection molding data to obtain the corresponding mold performance information, including: The shear rate of the injection molding data is calculated to obtain the shear rate of different parts during the injection molding process. The shear rate is a physical quantity that describes the melt flow velocity gradient and has an important influence on the melt flow behavior. The mold cavity shape, injection pressure, injection speed and other factors are considered in the calculation. The finite element analysis method is used to discretize the mold cavity into grid units, and the local shear rate is calculated in each unit.

[0053] Based on the calculated shear rate, the melt viscosity distribution of the instrument panel mold structure is calculated to obtain the viscosity distribution data. Melt viscosity is an important parameter that characterizes the flow resistance of the melt.

[0054] The pressure field simulation is performed using the viscosity distribution data and shear rate to obtain the rheological characteristics of the melt in the mold. The pressure field simulation is numerically solved using the finite volume method. The simulation results include rheological parameters such as pressure and velocity at each point in the mold, reflecting the flow characteristics of the melt in the mold.

[0055] Based on the rheological characteristics of the melt in the mold, the temperature field analysis of the instrument panel mold structure is carried out to obtain the mold temperature distribution data. The temperature field analysis uses the heat conduction equation, taking into account the convection heat transfer caused by the melt flow and the heat dissipation of the mold cooling system, and calculates the temperature distribution of each part of the mold. The temperature distribution has an important influence on the product molding quality and mold life.

[0056] The instrument panel mold structure is subjected to warpage deformation analysis based on the mold temperature distribution data to obtain the mold warpage deformation data. The warpage deformation analysis is based on the thermal-structural coupling model, taking into account the thermal stress and shrinkage stress caused by uneven temperature distribution, and calculating the deformation of each part of the mold. Warpage deformation will affect the product dimensional accuracy and appearance quality.

[0057] Based on the mold warpage deformation data, the stress and strain analysis of the instrument panel mold structure is carried out to obtain the mold stress and strain distribution data. The stress and strain analysis uses a linear elastic mechanics model, considers the elastic modulus and Poisson's ratio of the mold material, and calculates the stress and strain state of each part of the mold. The stress and strain distribution reflects the force condition of the mold and is an important basis for evaluating the strength and stiffness of the mold.

[0058] The durability of the instrument panel mold structure is evaluated based on the mold stress-strain distribution data to obtain the mold durability data. The durability evaluation is based on the fatigue life theory and the SN curve of the mold material to calculate the expected service life of the mold under cyclic loads. The durability data reflects the long-term performance of the mold.

[0059] The mold durability data and mold temperature distribution data are comprehensively evaluated to obtain the comprehensive performance information of the mold. The comprehensive performance evaluation adopts a multi-objective optimization method, takes durability and temperature uniformity as evaluation indicators, and comprehensively considers the long-term use performance of the mold and the product molding quality to obtain the comprehensive performance score of the mold.

[0060] This embodiment achieves accurate prediction of the performance of the instrument panel mold by performing a comprehensive analysis and multi-step simulation of the injection molding data. From shear rate calculation to comprehensive performance evaluation, key physical parameters and process factors are considered in each step to ensure the accuracy and reliability of the prediction results. The use of advanced numerical simulation methods, such as finite element analysis and thermal-structural coupling models, can deeply reveal the complex physical processes inside the mold, providing a scientific basis for mold design and optimization. The long-term performance of the mold is predicted through durability evaluation, which helps to improve the service life and production efficiency of the mold. The comprehensive performance evaluation adopts a multi-objective optimization method to balance multiple indicators such as mold life and product quality, providing a comprehensive reference for mold design and production decisions.

[0061] In one embodiment, a solution analysis is performed on the real-time mold state information and mold performance information to obtain an initial mold control solution, including: The collected real-time mold status information is associated with the pre-stored mold performance information. Real-time mold status information includes real-time monitoring data such as mold temperature, pressure, injection speed, etc. Mold performance information includes mold design parameters, material properties, historical production data, etc. The association process establishes a corresponding relationship between the real-time status and the performance index through a data matching algorithm to obtain associated information reflecting the current working status of the mold.

[0062] Comprehensively evaluate the relevant information to obtain the comprehensive mold status evaluation result. The evaluation process adopts a multi-dimensional scoring model to quantitatively score the mold status from aspects such as mold life, product quality, and production efficiency, and calculates a comprehensive score based on the weight of each dimension as the mold status evaluation result.

[0063] Based on the comprehensive mold status evaluation results, the associated information is analyzed for abnormalities to identify abnormal mold performance points. Abnormal analysis uses statistical process control methods to compare the evaluation results with the preset normal range, and data points outside the range are marked as abnormal points. These abnormal points reflect that the mold has performance problems in some aspects.

[0064] Optimize and adjust the design of the detected abnormal points in mold performance and formulate corresponding abnormal improvement strategies. According to the type and degree of the abnormal points, combined with mold structure and process knowledge, design targeted improvement measures, such as adjusting the cooling system, optimizing the pouring system, modifying the mold structure, etc., to form a specific abnormal improvement strategy.

[0065] According to the abnormal improvement strategy, the parameters of the associated information are identified to obtain a specific mold parameter adjustment plan. Through simulation and data analysis, the specific parameters and their value ranges that need to be adjusted to implement the improvement strategy are determined, such as the adjustment plan of key process parameters such as mold temperature, injection pressure, and holding time.

[0066] Integrate the mold parameter adjustment plan and abnormal improvement strategy to form a complete initial mold control plan.

[0067] This embodiment achieves a comprehensive grasp of the current working status of the mold by associating real-time mold status information with mold performance information, providing a rich data basis for subsequent analysis. The use of a multi-dimensional scoring model for comprehensive evaluation makes the quantification of mold status more accurate and objective, which helps to discover potential problems in a timely manner. Abnormal analysis based on the evaluation results can quickly locate abnormal points in mold performance, improving the efficiency and accuracy of problem diagnosis. The optimization and adjustment strategy formulated for abnormal points ensures the pertinence and effectiveness of improvement measures. The specific adjustment plan obtained through parameter identification provides operational guidance for mold control and improves the accuracy and reliability of control. The initial mold control plan finally integrated takes into account structural optimization and parameter adjustment, providing a systematic solution for improving mold performance and product quality.

[0068] In one embodiment, parameter identification is performed on the injection molding data to obtain corresponding injection molding process parameters, and the injection molding process parameters are adaptively adjusted based on the mold performance information to obtain corresponding adjusted process parameters, including: The injection molding data is multi-dimensionally decomposed into parameter sequences of four dimensions: temperature, pressure, speed, and time. These parameter sequences are then processed by nonlinear time series analysis methods to extract dynamic features and form a dynamic feature set. Dynamic features include but are not limited to parameter change trends, periodicity, mutation points, etc.

[0069] Based on the obtained dynamic feature set, the injection molding process parameter space is constructed. This space is a multi-dimensional parameter representation, and each dimension corresponds to a process parameter. Use a spatial clustering algorithm (such as K-means or DBSCAN) to partition this parameter space to obtain the initial injection molding process parameters. The spatial clustering algorithm calculates the distance between parameters and clusters similar parameters together to form different parameter combinations.

[0070] The initial injection molding process parameters are optimized and adjusted based on the mold performance information. The mold performance information includes mold material characteristics, structural design, cooling system efficiency, etc. The optimization and adjustment process first sets the constraints of the process parameters according to the mold performance information, such as upper and lower temperature limits, pressure range, etc. At the same time, the optimization objective function including product quality and production efficiency is defined, which may involve the weighted sum of multiple factors such as product qualification rate, production cycle, energy consumption, etc.

[0071] Under the constraints, an iterative optimization algorithm (such as a genetic algorithm or a particle swarm optimization algorithm) is used to optimize the initial injection molding process parameters. In each iteration, the objective function value of the current parameter combination is evaluated to obtain an evaluation result. The evaluation result is used to judge the quality of the current parameter combination. According to the evaluation result, a parameter combination with better performance is selected for crossover mutation to generate a new parameter combination. The crossover mutation operation simulates the biological evolution process and explores a better solution by combining and fine-tuning existing parameters.

[0072] The iteration process continues until the preset iteration goal is reached. The iteration goal can be to reach a certain target function value, or the improvement of the target function value after multiple consecutive iterations is less than a predetermined threshold. The parameter combination obtained by the final iteration is the adjusted process parameter, which can achieve a good balance between product quality and production efficiency while meeting the mold performance constraints.

[0073] This embodiment realizes accurate parameter identification of complex injection molding process and improves the accuracy of process parameter setting by multi-dimensional decomposition and nonlinear time series analysis of injection molding data. By constructing injection molding process parameter space and performing spatial clustering, a large number of parameter combinations are effectively simplified into representative initial parameters, greatly improving the efficiency of parameter optimization. Adaptive adjustment is performed based on mold performance information, so that the optimized process parameters can better adapt to the characteristics of different molds, improving the flexibility and versatility of mold use. The iterative optimization algorithm is used to find the best balance between product quality and production efficiency, which not only ensures product quality but also improves production efficiency. By setting constraints and optimizing objective functions, the practicality and reliability of the optimization results are ensured. The whole process realizes the intelligent adjustment of injection molding process parameters, reduces human intervention, and improves the stability and consistency of the production process.

[0074] In one embodiment, the initial mold control solution is optimized according to the adjusted process parameters to obtain a corresponding global adjustment strategy, including: The initial mold control scheme is subjected to parameter hierarchical analysis to obtain the parameter importance ranking. Parameter hierarchical analysis is a multi-criteria decision-making method that decomposes complex problems into various components by establishing a hierarchical model, and compares these factors in pairs to finally obtain the relative importance of each parameter. In this embodiment, a hierarchical analysis is performed on various process parameters of the injection mold, such as temperature, pressure, time, etc., and the weight of each parameter is calculated to obtain the ranking result of the parameter importance.

[0075] Based on the parameter importance ranking, an orthogonal test design is performed on the initial mold control scheme to obtain the test scheme. Orthogonal test design is an efficient experimental design method that reduces the number of tests by selecting representative test point combinations. According to the parameter importance ranking, key parameters are selected, an orthogonal test table is designed, and the level of each parameter is determined to obtain a set of optimized test schemes.

[0076] The test scheme is simulated and run to obtain simulation results. Simulation is to conduct virtual experiments on the test scheme through computer simulation software to predict the situations that may occur in actual production. By using professional injection molding simulation software, inputting various parameters in the test scheme, and performing virtual injection molding process, simulation results can be obtained, including indicators such as product quality and production efficiency.

[0077] According to the preset decision rule set, the simulation results are analyzed by decision tree to obtain decision modification information. The decision rule set is a series of judgment criteria developed based on expert experience and historical data, which is used to evaluate the quality of simulation results. Decision tree analysis is an intuitive data mining method that represents the decision process by constructing a tree structure. The simulation results are compared with the decision rule set, a decision tree is constructed, and the impact of each parameter on the results is analyzed, so as to obtain the parameters that need to be modified and the modification direction.

[0078] The initial mold control scheme is adaptively adjusted according to the decision modification information to obtain an adaptive adjustment control scheme. Adaptive adjustment refers to the process of automatically adjusting control parameters according to feedback information. According to the decision modification information, the relevant parameters in the initial mold control scheme are adjusted, such as adjusting the injection temperature, pressure or time, so as to obtain an optimized adaptive adjustment control scheme.

[0079] The adaptive control scheme is matched with the preset control mode library to obtain the control mode. The control mode library is a database containing a variety of typical injection molding process modes, each of which corresponds to a specific product type and production requirements. The parameters of the adaptive control scheme are compared with each mode in the control mode library, and the best matching control mode is selected as the optimization direction.

[0080] The adaptive adjustment control scheme is integrated with the control mode to obtain the global adjustment strategy.

[0081] This embodiment realizes the scientific optimization of mold control parameters through parameter hierarchy analysis and orthogonal experimental design, greatly improving the efficiency and accuracy of parameter adjustment. The combination of simulation operation and decision tree analysis makes it possible to predict and evaluate the effects of various parameter combinations before actual production, effectively reducing trial and error costs and waste of resources. The adaptive adjustment mechanism can flexibly adjust the control scheme according to real-time feedback, improving the flexibility and adaptability of mold control. The integration of the adaptive adjustment scheme with the preset control mode not only ensures the reliability of the control scheme, but also takes into account personalized needs, achieving a balance between standardization and customization of mold control. The entire optimization process forms a closed-loop control strategy that can continuously improve the mold control effect, improve product quality and production efficiency.
