Description

Technical Field

[0001] The present application relates to the field of mold flow simulation technology, and in particular to a method, device, equipment and storage medium for adjusting screw curve parameters. Background Art

[0002] Screw curve parameters describe the motion characteristics of the screw during the injection molding process. These parameters directly affect the plasticization quality of the melt, injection pressure, filling time, and the performance of the final product. Therefore, during the injection molding process, screw curve parameters need to be adjusted to ensure that the final product meets the requirements.

[0003] Currently, screw curve parameter adjustments are performed by inputting parameters related to screw stroke and speed into simulation software, simulating the screw's motion during the injection molding process and generating corresponding simulation results. The user then adjusts the screw curve parameters (including speed, back pressure, melt temperature, etc.) based on the simulation results and experience, and repeats the simulation. This cycle continues until the simulation results meet the user's needs, adjusting the parameters to achieve the optimal plasticizing effect. However, adjusting screw curve parameters involves multiple variables, which also have complex interactions, requiring the user to adjust parameters multiple times and perform simulations, resulting in inefficient adjustment.

[0054] It should be understood that the specific embodiments described herein are merely used to explain the technical solutions of the present application and are not intended to limit the present application.

[0055] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0056] The main solution of the embodiment of the present application is: the controller of the injection molding machine performs simulation analysis on the product to be injected, and obtains the screw speed curve of the screw obtained after the simulation analysis of the product to be injected; based on the recommended screw speed and percentage injection volume in the screw speed curve, a screw fitting curve corresponding to the screw speed curve is generated; based on the screw speed curve, the screw fitting curve and the density data of the required raw materials of the product to be injected during the simulation analysis process, the target movement stroke and target movement speed required for the screw are determined; based on the target movement stroke and the target movement speed, the screw curve parameters required for production are adjusted.

[0057] In this embodiment, for ease of description, the following description is made with the controller of the injection molding machine as the execution subject.

[0058] Adjusting screw curve parameters involves inputting parameters related to screw stroke and speed into simulation software, simulating screw movement during the injection molding process, and generating corresponding simulation results. The user then adjusts screw curve parameters (including speed, back pressure, melt temperature, etc.) based on these simulation results and experience, and repeats the simulation, repeating this cycle until the simulation results meet the user's needs and achieve the optimal plasticizing effect. However, adjusting screw curve parameters involves multiple variables, and these variables also have complex interactions, requiring the user to adjust parameters and perform simulations multiple times, resulting in inefficient adjustment.

[0059] The present application provides a solution, which performs simulation analysis on the product to be injection molded and obtains a screw speed curve obtained after the simulation analysis, so that the correspondence between the screw speed and the injection volume can be quickly determined from the screw speed curve, reducing the analysis of too many parameters and avoiding interference from other parameters. According to the recommended screw speed and percentage injection volume in the screw speed curve, a screw fitting curve corresponding to the screw speed curve is generated. Since the screw fitting curve can accurately predict the performance of the screw under different conditions, combined with the density data of the required raw materials of the product to be injection molded during the simulation process, it can accurately reflect the plasticization situation of the required raw materials of the product during the injection molding process. Therefore, the target movement stroke and target movement speed of the screw can be accurately and quickly determined through the screw speed curve, the screw fitting curve and the density data, reducing the number of simulations, and adjusting the screw curve parameters required for the production of the product to be injection molded according to the target movement stroke and target movement speed, reducing the number of adjustments to the screw curve parameters, thereby improving the adjustment efficiency of the screw curve parameters.

[0060] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, mobile phone, etc., or an electronic device capable of implementing the above functions, such as an injection molding machine controller. The following uses the injection molding machine controller as an example to illustrate this embodiment and the following embodiments.

[0061] Based on this, the embodiment of the present application provides a method for adjusting screw curve parameters, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the screw curve parameter adjustment method of the present application.

[0062] In this embodiment, the screw curve parameter adjustment method includes steps S10 to S40:

[0063] Step S10, performing simulation analysis on the product to be injection molded, and obtaining a screw speed curve obtained after the simulation analysis of the product to be injection molded;

[0064] It should be noted that products to be molded are products that have been designed but have not yet been manufactured, that is, products that need to be produced through injection molding. Simulation analysis is a technical method that uses computers to simulate the actual production process. The screw speed curve is a functional curve that plots the recommended screw speed as a function of the percentage shot volume during the injection molding process.

[0065] It is understandable that since the screw speed curve can reflect the speed change law of the screw in different injection stages, before injection molding production, the designed product to be injected is first simulated and analyzed to simulate the injection molding process by computer and predict the flow of the raw materials of the product to be injected in the mold, so as to obtain the screw speed curve of the screw and obtain the reference data required for subsequent screw parameter adjustment.

[0066] In the specific implementation, a three-dimensional model of the product to be injection molded and a mold model are first established, and the physical properties of the raw materials of the product to be injection molded and the injection molding process parameters (for example, injection time and temperature, etc.) are set through simulation software. Then, the simulation software is run to simulate the injection molding process of the product to be injection molded to obtain the simulation analysis results. Then, based on the percentage injection volume and the recommended screw curve in the simulation analysis results, a screw speed curve is obtained to intuitively display the speed change trend of the screw throughout the injection molding process and the injection volume change trend of the raw materials of the product to be injection molded.

[0067] Step S20, generating a screw fitting curve corresponding to the screw speed curve based on the recommended screw speed and the percentage injection volume in the screw speed curve;

[0068] It should be noted that the recommended screw speed is the recommended screw movement speed during the injection phase, determined during simulation analysis based on optimization algorithms or empirical rules. The injection molding machine controller can set this recommended screw speed as the actual screw speed in production (after receiving user confirmation) or use it as a reference to adjust the screw speed based on actual conditions. The percentage shot volume is the percentage of the injected material volume of the product to be molded as a percentage of the total shot volume during the injection molding process. It is used to describe the characteristic point locations of the screw speed curve and the screw fitting curve. The screw fitting curve is a smooth curve obtained by fitting the recommended screw speed and percentage shot volume in the screw speed curve.

[0069] It should be noted that the screw fitting curve and the screw speed curve are similar in shape and area, and the screw fitting curve is a curve that is smoothly adjusted according to actual production conditions to better adapt to the screw parameter adjustment requirements in actual production.

[0070] It can be understood that after obtaining the screw speed curve, a screw fitting curve is further generated. By fitting the recommended screw speed and percentage injection volume in the screw speed curve and combining it with actual production conditions, a smoother and easier to apply screw fitting curve is obtained. The screw fitting curve can be used to provide a basis for subsequent adjustment of the screw curve parameters that is closer to actual production, so that the data related to the screw curve parameters finally obtained can be more accurate.

[0071] It is understandable that since the relationship between the screw speed and the percentage injection volume in the screw fitting curve is more applicable to actual production conditions, using the screw fitting curve as a tool to adjust the screw curve parameters can narrow the range of adjustment of the screw curve parameters, thereby reducing the number of simulation analyses and improving the efficiency of screw curve parameter adjustment.

[0072] It can be understood that the smoothed screw fitting curve is easier for the injection molding machine controller to accurately track, and the screw speed and percentage injection volume in the screw fitting curve are realized to improve the accuracy of the screw movement, ensure uniform filling of the raw materials of the product to be injection molded, and further improve product quality.

[0073] In practice, fitting can be performed using mathematical fitting algorithms, such as polynomial fitting and spline fitting. For example, a polynomial fitting curve can be constructed based on several key points in the screw speed curve (e.g., the percentage injection volume points corresponding to the recommended screw speed). The order of the fitting curve can be selected based on actual needs and fitting accuracy requirements.

[0074] Optionally, step S20 may further include:

[0075] performing fitting processing on the screw speed curve based on the recommended screw speed and the percentage injection volume in the screw speed curve to generate a screw fitting curve corresponding to the screw speed curve;

[0076] The first area enclosed by the screw fitting curve and the horizontal and vertical coordinates is equal to the second area enclosed by the screw speed curve and the horizontal and vertical coordinates.

[0077] It should be noted that the horizontal axis represents the percentage injection volume, and the vertical axis represents the screw speed, so that the screw speed curve can intuitively show the speed changes of the screw in different injection stages.

[0078] It should be noted that the first area is obtained by integrating the screw speed curve, which represents the total injection volume of the screw during the entire simulation analysis process; the second area is obtained by integrating the screw fitting curve, which represents the total injection volume required after the screw speed curve is fitted.

[0079] It can be understood that fitting the screw speed curve can eliminate the sudden changes and irregular fluctuations in the original speed curve, making the screw fitting curve more consistent with the actual injection molding conditions, and smooth control can also improve the accuracy of injection molding.

[0080] It can be understood that when generating the screw fitting curve, ensuring that the area enclosed by the fitting curve and the horizontal and vertical coordinates (first area) is equal to the area enclosed by the screw speed curve and the horizontal and vertical coordinates (second area) can ensure that the total injection volume of the screw fitting curve in the entire injection molding process is consistent with the total injection volume of the original screw speed curve, thereby ensuring that the injection molding process remains unchanged.

[0081] Step S30, determining a target movement stroke and a target movement speed required for the screw based on the screw speed curve, the screw fitting curve, and density data of the raw material required for the product to be injection molded during the simulation analysis process;

[0082] It should be noted that the target travel distance is the effective distance the screw needs to move to complete the injection molding task during the injection molding process. The target travel speed is the effective travel speed that the screw needs to achieve within the target travel distance during the injection molding process.

[0083] It should be noted that the density data refers to the density value of the raw material of the product to be injection molded under different pressures and conditions during the simulation analysis process.

[0084] It can be understood that by combining the screw speed curve, screw fitting curve, and material density data, the target screw travel and target speed can be accurately calculated to ensure the precise volume of material in each injection of the molded product, thereby improving the dimensional consistency and weight stability of the product. Furthermore, the precise target travel and speed ensure that the required material is evenly filled in the mold cavity, reducing defects caused by underfilling or overfilling, thereby improving the surface and internal quality of the product and reducing the defective rate.

[0085] In a specific implementation, the screw speed curve and the screw fitting curve can be divided into two or four segments (three segments are also possible, depending on the actual situation). If the screw speed curve and the screw fitting curve are divided into two segments, the area of ​​the first segment of the screw fitting curve should be equal to the area of ​​the first segment of the screw speed curve, and the area of ​​the second segment of the screw fitting curve should also be equal to the area of ​​the second segment of the screw speed curve. Both the first and second segments of the screw fitting curve should be smooth. Based on the pseudo-screw fitting curve and the screw speed curve for each segment, the screw travel and speed ranges within different injection volume ranges are determined. Combined with the raw material density data, the effective volume of the raw material required for the product to be injected is determined. Based on the effective volume and the proposed speed and injection volume in the screw fitting curve, the screw's target travel and speed are further determined. Once both the target travel and speed are verified, the target travel is determined as the target stroke, and the target speed is determined as the target speed.

[0086] Step S40 : adjusting screw curve parameters required for production based on the target movement stroke and the target movement speed.

[0087] It can be understood that by adjusting the screw curve parameters required for production according to the target movement stroke and target movement speed of the screw, the screw curve parameters can be made more in line with the actual production situation. Moreover, due to the target movement stroke and target movement speed of the screw, the raw material volume of the product to be injected each time can be accurately characterized. By adjusting the screw curve parameters required for production according to the target movement stroke and target movement speed of the screw, it is also possible to achieve precise control of the screw during the production process to improve product performance and production efficiency.

[0088] In specific implementation, according to actual production needs, by determining the pressure and temperature parameters of the screw, the density data of the required raw materials for the injection-molded product at the corresponding pressure and temperature can be determined, and then the screw speed curve is adjusted according to the target movement speed determined based on the density data to ensure that the speed of the screw in different injection stages meets the target requirements, so as to ensure that the quality of the product after injection molding meets the required quality. According to the target movement stroke and target movement speed determined based on the density data, the acceleration and deceleration of the screw at different times can be determined. Therefore, the acceleration and deceleration of the screw can be adjusted according to the target movement stroke and speed to ensure smooth start and stop of the screw, and the stroke parameters of the screw can be adjusted according to the target movement stroke to ensure that the screw can move accurately according to quality requirements, thereby realizing the adjustment of the screw curve parameters (pressure and temperature parameters, acceleration and deceleration, and stroke parameters) required for production.

[0089] This embodiment provides a method for adjusting screw curve parameters. By performing simulation analysis on a product to be injection molded, a screw speed curve obtained after the simulation analysis is obtained, so that the corresponding relationship between screw speed and injection volume can be quickly determined from the screw speed curve, reducing the analysis of excessive parameters and avoiding interference from other parameters. A screw fitting curve corresponding to the screw speed curve is generated based on the recommended screw speed and percentage injection volume in the screw speed curve. Since the screw fitting curve can accurately predict the performance of the screw under different conditions, combined with the density data of the required raw materials of the product to be injection molded during the simulation process, it can accurately reflect the plasticization of the required raw materials of the product during the injection molding process. Therefore, the target movement stroke and target movement speed of the screw can be accurately and quickly determined through the screw speed curve, the screw fitting curve and the density data, reducing the number of simulations. The screw curve parameters required for producing the product to be injection molded are adjusted according to the target movement stroke and target movement speed, reducing the number of adjustments to the screw curve parameters, thereby improving the efficiency of adjusting the screw curve parameters.

[0090] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above embodiment 1 can be referred to the above introduction and will not be described in detail later. Figure 2 , step S30 also includes steps S01 to S03:

[0091] Step S01, obtaining a screw stroke and a screw speed to be verified based on the screw speed curve, the screw fitting curve, and density data of the raw material required for the product to be injection molded during the simulation analysis process;

[0092] Step S02, simulating the injection molding of the product to be injected based on the stroke to be verified and the speed to be verified, to obtain predicted quality information of the product to be injected;

[0093] Step S03: If the predicted quality information does not meet the preset quality requirements, the screw speed curve is adjusted, and the process returns to the step of generating a screw fitting curve corresponding to the screw speed curve based on the recommended screw speed and percentage injection volume in the screw speed curve, until the predicted quality information meets the preset quality requirements, and the latest stroke to be verified is determined as the target moving stroke, and the latest speed to be verified is determined as the target moving speed.

[0094] It should be noted that the stroke to be verified is the preliminary movement stroke of the screw calculated through simulation analysis based on the screw speed curve, the screw fitting curve and the raw material density data. This stroke needs to be verified through a simulated injection molding process to determine whether the stroke to be verified meets the preset quality requirements. The speed to be verified is the preliminary movement speed of the screw calculated through simulation analysis based on the screw speed curve, the screw fitting curve and the raw material density data. This speed also needs to be verified through a simulated injection molding process to determine whether the speed to be verified meets the preset quality requirements. The predicted quality information is the quality information of the product to be injected obtained through a simulated injection molding process. The preset quality requirements are the product quality standards set during the production process. The quality standards may include the product's dimensional tolerance, surface roughness, internal defect allowable range, etc., to be used to evaluate whether the results of the simulated injection molding process meet production requirements.

[0095] It can be understood that by iteratively adjusting and verifying the screw curve parameters, it is ensured that the final screw curve parameters can meet the preset quality requirements, thereby reducing the deviation between the simulation results and actual production and improving the accuracy and reliability of the simulation.

[0096] It can be understood that the injection molding process of the injection molded product is simulated and analyzed using simulation software, and the stroke and speed to be verified obtained based on the simulation analysis are iteratively adjusted and verified to obtain the target stroke and target moving speed, so as to adjust the screw curve parameters according to the target moving stroke and target moving speed finally obtained, and then use the screw curve parameters obtained based on the simulation analysis in the actual injection molding of the injection molded product, so as to discover potential quality problems of the injection molded product and problems with the injection molding process before actual production, thereby avoiding production waste and increased defective rate due to unreasonable parameters.

[0097] In specific implementations, the screw speed profile and screw fitting curve are used to determine the screw speed distribution during different injection stages. Combined with the density data of the required raw material, the effective volume of the required raw material is determined, thereby determining the screw travel. The corresponding travel speed can also be determined based on the screw fitting curve. This results in the screw's intended travel and speed. Injection molding simulation software is then used to simulate the flow, filling, and cooling of the required raw material in the mold cavity based on the intended travel and speed to assess whether the intended travel and speed meet product quality requirements. If not, the screw fitting curve is readjusted. The adjusted screw fitting curve is re-calculated for the screw's intended travel and speed, and injection molding simulation is repeated until the intended travel and speed meet product quality requirements. The finalized travel and speed are then used as the target travel and speed.

[0098] Furthermore, step S01 further includes:

[0099] Performing equal-area processing on the screw speed curve and the screw fitting curve to obtain the proposed speed and the proposed injection volume of each segment in the screw fitting curve;

[0100] Determining the effective volume of the required raw material based on the proposed injection volume and density data of the required raw material of the product to be injection molded during the simulation analysis process;

[0101] Based on the effective volume and the planned speed, a stroke to be verified and a speed to be verified of the screw are determined.

[0102] It should be noted that equal-area processing ensures that the area enclosed by the screw fitting curve and the horizontal and vertical coordinates is equal to the area enclosed by the screw speed curve and the horizontal and vertical coordinates when generating the screw fitting curve. This ensures consistent injection volume and the physical meaning of the injection molding process. The proposed speed is the screw movement speed of each segment in the screw fitting curve, obtained using equal-area processing. The proposed injection volume is the injection volume of each segment in the screw fitting curve, obtained using equal-area processing. The effective volume is the volume of raw material actually required to fill the mold cavity and runners during the injection molding process.

[0103] It can be understood that by combining the proposed injection volume and raw material density data, the effective volume of the required raw material can be accurately calculated to ensure the accurate volume of the plastic melt for each injection, thereby improving the dimensional consistency and weight stability of the product.

[0104] It can be understood that by combining the effective volume and the proposed speed, the accuracy of the simulated injection molding process can be improved, making the initially determined parameters closer to the actual needs, and providing a basis for subsequent verification and adjustment.

[0105] It should be noted that the density data includes the first density of the required raw material at zero pressure, the second melt density of the required raw material at V / P switching pressure, and the solid density and melt density of the required raw material.

[0106] Furthermore, the step of determining the effective volume of the required raw material based on the planned injection volume and the density data of the required raw material of the product to be injection molded during the simulation analysis process includes:

[0107] The effective volume of the required raw material is determined based on the planned injection volume and the first density, the second density, the solid density, and the melt density.

[0108] It is understandable that accurate density data helps optimize the injection molding process and reduce defects caused by density changes, such as shrinkage and bubbles, thereby improving the accuracy of the target movement stroke and target movement speed, and further improving the quality of the injection molded products during the production process.

[0109] In the specific implementation, based on the analysis results of the simulation, record the solid density and melt density of the product to be injected under the corresponding material UDB. Record the volume specific volume data corresponding to the set temperature when the pressure is 0MPa and the pressure is at the V / P switching pressure (reference Figure 3 ). Substituting the above data into the function formula, we can get the effective volume of the product to be injected in the mold cavity and runner.

[0110] The function formula is:

[0111] ;

[0112] in, is the effective volume of the product in the mold cavity, is the density of the solid, is the melt density, is the density of the raw material required when the pressure is 0 MPa, It is the density of the raw material required when the pressure is V / P switching pressure, is the planned injection volume of the product in the mold cavity, It is the effective volume of the product in the runner of the mold. The planned injection volume of the product within the runner of the mold.

[0113] It should be noted that the effective volume of the product to be injected may be the sum of the effective volume of the product in the mold cavity and the effective volume of the product in the runner.

[0114] Furthermore, the step of determining the screw stroke to be verified and the speed to be verified based on the effective volume and the planned speed includes:

[0115] Determining, based on the effective volume, a target injection molding machine model and a corresponding screw diameter required for injection molding the product to be injection molded;

[0116] Determining a stroke of the screw to be verified based on the screw diameter and the effective volume;

[0117] The speed to be verified corresponding to the stroke to be verified is queried from the screw fitting curve.

[0118] It should be noted that the target injection molding machine model refers to the most suitable injection molding machine model for injection molding production, selected based on the effective volume of the product to be molded and production requirements. Different injection molding machine models have different technical parameters, such as maximum injection volume, screw diameter, and injection pressure. The screw diameter refers to the outer diameter of the injection molding machine screw and directly affects the screw's conveying capacity and injection volume. Specifically, the appropriate screw diameter can be determined based on the effective volume of the product to be molded and the injection molding machine model.

[0119] It is understandable that by selecting the appropriate target injection molding machine model and screw diameter, the data of the screw required to produce the product to be injection molded can be combined to further determine the stroke and speed to be verified in the screw curve parameters, thereby reducing the number of simulations and improving the accuracy of the simulation analysis.

[0120] In practice, the injection volume requirements for the product to be molded are assessed based on the effective volume. Based on this volume requirement, an injection molding machine model with sufficient injection capacity is selected. The corresponding screw diameter is then determined based on the machine model to ensure that the data obtained from the simulation analysis is consistent with the actual injection molding process. Based on the effective volume and screw diameter, the required screw travel is calculated. Combined with the screw fitting curve, the point corresponding to the travel to be verified is found and the speed to be verified at that point is determined.

[0121] Based on the first and second embodiments of the present application, in the third embodiment of the present application, the same or similar contents as those in the above embodiments can be referred to the above introduction and will not be described in detail later. Figure 4 Before step S30, the screw curve parameter adjustment method further includes steps S1 to S3:

[0122] Step S1, obtaining the injection time of the raw material required for simulation analysis of the injection molded product;

[0123] Step S2, performing simulation analysis on the product to be injection molded based on the injection time to obtain an effective injection time;

[0124] Step S3: determining a recommended screw speed of the screw based on the effective injection time and the simulation process of the screw.

[0125] It should be noted that the injection time is the pre-set time from the start of screw movement to the completion of injection during the injection molding process. The effective injection time is the injection time of the plastic melt that actually participates in filling the mold cavity during the injection molding process.

[0126] It is understandable that due to fluctuations in the product to be injected during the simulation analysis or the actual injection molding process, the actual injection time is different from the preset injection time. Therefore, it is necessary to perform a simulation analysis on the product to be injected based on the injection time to determine the effective injection time to ensure the accuracy of the subsequent analysis of the target movement stroke and target movement speed.

[0127] Furthermore, the step of performing simulation analysis on the product to be injection molded and obtaining a screw speed curve obtained after the simulation analysis of the product to be injection molded includes:

[0128] Performing simulation analysis on the product to be injected, and obtaining a percentage injection volume of the product to be injected obtained after the simulation analysis on the product to be injected;

[0129] Based on the percentage injection volume and the recommended screw speed, a screw speed curve of the screw is obtained after simulation analysis of the product to be injection molded.

[0130] It can be understood that by generating a screw speed curve to optimize the motion behavior of the screw, the filling uniformity of the plastic melt and the product quality are ensured.

[0131] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the screw curve parameter adjustment method of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.
