The research and development of stamping molds involves many aspects, including material selection, design methods, manufacturing processes and quality control. Among them, the material selection of stamping molds is crucial and directly affects the performance and life of the mold. Commonly used stamping mold materials include carbon tool steel, low alloy tool steel, high carbon high chromium tool steel, high speed steel, cemented carbide, steel bonded cemented carbide, cast iron, cast steel, stainless steel (containing titanium and vanadium), high alloy steel and chromate alloy. These materials have their own advantages and disadvantages and need to be selected according to specific working conditions and requirements.

[0065] The following is combined with Figure 1-9 This application is described in further detail.

[0066] The present application embodiment discloses a rapid verification method for mold development. Figure 1 , a rapid verification method for mold development, comprising the following steps:

[0067] S1. Receive in real time the mold design plan sent by the mold R&D department; the mold design plan includes basic product information, mold drawing information, mold material parameters, mold stamping process information and mold manufacturing process information; the mold drawing information includes finished mold drawing information and trial mold drawing information, and the trial mold drawing information includes view information, dimensioning information and assembly requirement information of the upper mold base component, the lower mold base component and multiple functional modules; the functional module is one of a customized module and a general module; the assembly requirement information includes assembly part specification information, assembly sequence and assembly accuracy;

[0068] S2. Perform mold stamping operation simulation through CAE software: Perform mold stamping operation simulation through CAE software according to the mold design plan and generate simulation analysis results, wherein the simulation analysis results include analysis conclusions and simulation process data;

[0069] S3, judging whether there is defect information in the simulation analysis results;

[0070] S4. Send to mold R&D department for solution modification: If there is, the mold design solution and simulation analysis results are sent to the mold R&D department for solution modification;

[0071] S5. Generate manufacturing requirements and send them to the mold manufacturing department: If they do not exist, obtain the functional module inventory information, determine the missing functional modules according to the mold design plan, generate manufacturing requirements and send them to the mold manufacturing department for functional module manufacturing;

[0072] S6. Assembling a trial mold: assembling an upper mold base component, a lower mold base component and a plurality of functional modules according to the mold design plan and assembly requirements to obtain a trial mold;

[0073] S7. Trial mold processing verification plan: Install the trial mold on the stamping equipment for trial mold processing, judge whether the mold design plan is qualified based on the trial mold processing results, and send the trial mold processing results to the mold R&D department. Through the above steps, the developed mold design plan is verified efficiently and at low cost. For the mold design plan developed by the mold R&D department, the CAE software is first used for simulation operation, and the mold design plan is preliminarily screened to determine its feasibility. For the feasible and correct schemes in the simulation operation, the developed mold is modularized through the trial mold drawing information, breaking the whole into parts, calling the general modules in stock, and then customizing the mold design plan to distinguish it from other molds. Customized modules can effectively reduce R&D costs, reduce mold manufacturing cycles, speed up problem location and correction, and improve mold R&D verification efficiency and verification accuracy.

[0074] And when faced with difficult mold development tasks, as the mold solution is continuously verified and modified, in addition to the first need to manufacture the customized module, subsequent verification only requires remanufacturing the modified module, which can further save R&D costs and manufacturing time. The more R&D revisions, the more savings.

[0075] Traditional mold trials usually require the manufacture of the entire mold for verification according to the complete mold design plan. This may result in the previously manufactured parts being discarded if problems with the mold need to be modified during the mold trial, resulting in material waste and a long mold manufacturing cycle. Through modular splitting, the general modules in stock can be used directly, and only customized modules need to be manufactured. This can reduce unnecessary material procurement, especially for some expensive mold materials, and can effectively shorten the mold manufacturing time. In addition, problems are very likely to occur during the development and verification of the initial version of the mold design plan. In traditional mold verification, since the entire mold is an integral structure, it may be necessary to conduct a detailed inspection and analysis of the entire mold to locate the problem. In modular molds, problems are easier to locate. If problems occur during mold trial, since the general module is verified, the problem often lies in the customized module. It can effectively improve the efficiency and accuracy of mold development and verification.

[0076] In order to further improve the efficiency of mold solution development and verification, after starting the mold development project, the mold development department uses the existing upper mold base component and lower mold base component as templates to draw upper and lower template drawings, and assemble modules based on this, develop and set up various functional modules, constitute mold drawing information, and then generate a mold design plan. Compared with first conducting research and development and then dividing the developed mold drawings into various upper mold base components, lower mold base components and functional modules, the mold design plan designed in this way can not only effectively shorten the research and development cycle, but also make the developed mold design plan more in line with the mold development rapid verification method of this application, further improve the efficiency of mold solution verification, increase the utilization rate of common modules, and reduce mold development costs.

[0077] CAE (Computer Aided Engineering) is an approximate numerical analysis method that uses computers to assist in solving complex engineering and product structural strength, stiffness, buckling stability, dynamic response, heat conduction, three-dimensional multi-body contact, elastic-plastic analysis and other mechanical properties, as well as the optimization design of structural performance. The CAE software suitable for this application is more recommended, including AutoForm, Dynaform, Moldflow and ANSYS.

[0078] Reference Figure 2 The method of simulating the stamping operation of the mold by using CAE software according to the mold design scheme and generating simulation analysis results specifically includes the following steps:

[0079] A1. Establish the 3D model of stamping die and product raw materials according to the die design plan, import CAE software and verify the integrity of the 3D model of stamping die;

[0080] A2. After the integrity verification is passed, the material properties of the stamping die and the three-dimensional model of the product raw material are set according to the die design plan;

[0081] A3. Define the stamping process of the stamping die in CAE software according to the die design plan;

[0082] A4. Start the CAE software to simulate the die stamping operation, simulate the stamping process of the stamping die, analyze the deformation and output the analysis conclusion;

[0083] A5. Collect data information during the simulation operation of stamping dies to generate simulation process data, and package the analysis conclusions and simulation process data to generate simulation analysis results. Through the above steps, the stamping operation simulation of the die can be performed through CAE software according to the die design plan, which can accurately analyze the performance of the die in a virtual environment, discover defects in the die design in advance and make modifications, and can perform preliminary verification and screening of the die design plan without actual processing and assembly operations, and timely discover die design plans with obvious defects, which helps to reduce the cost of die R&D verification, shorten the die R&D cycle, and achieve rapid response to market demand.

[0084] Reference Figure 3 The integrity verification of the three-dimensional model of the stamping die specifically includes the following steps:

[0085] B1. Confirm the model import status: Get the import result prompt of CAE software to confirm whether the 3D model is successfully imported;

[0086] B2. Model correction: If the import fails, an import error message is sent to the modeling technician for model correction. After the correction is completed, the model is re-imported into the CAE software and the process goes to step B1.

[0087] B3. Integrity verification: If the import is successful, the 3D model of the stamping die will be checked for model integrity, component connection relationship, and model accuracy;

[0088] B4. Problem repair: If there is an error, the error information is sent to the administrator for problem repair. After the problem is repaired, jump to step B3;

[0089] B5. Pass the integrity verification: If the inspection is correct, the 3D model of the stamping die passes the integrity verification. The above steps are used to verify the integrity of the 3D model of the stamping die to ensure that the model is accurate and the analysis results of the CAE software simulation are accurate, avoiding simulation calculation failures; a complete model enables CAE software to allocate computing resources more effectively during simulation, which can greatly improve simulation efficiency.

[0090] Reference Figure 4 The step of sending the mold design plan and simulation analysis results to the mold R&D department for plan modification specifically includes the following steps:

[0091] C1. Correction and generation of a corrected mold solution: the mold design solution and the simulation analysis results are input into a preset solution correction model, and the mold design solution is corrected to generate a corrected mold solution; the solution correction model is a convolutional neural network model, which is obtained by deep learning through historical mold R&D data; the specific training steps of the convolutional neural network model that need to be explained are prior art and will not be repeated here;

[0092] C2. Send to mold R&D department: package the revised mold plan, mold design plan and simulation analysis results to generate correction suggestions and send them to the mold R&D department;

[0093] C3. The management personnel of the mold R&D department confirm whether the correction suggestions are feasible based on the correction suggestions;

[0094] C4, sending to step S2 for scheme verification: if it is confirmed to be feasible, the revised mold scheme is sent to step S2 for scheme verification;

[0095] C5. Generate R&D debugging request: If it is confirmed to be infeasible, the correction suggestions will be packaged and converted into R&D debugging request and added to the R&D task bar of the mold R&D department. Through the above steps, for the mold analysis scheme with defects in simulation analysis, the scheme correction model can quickly and intelligently locate the scheme defects, objectively and accurately mine the defect characteristics and laws from the simulation data, automatically generate correction schemes, and accurately optimize parameters; it can effectively avoid the misjudgment and omission of certain potential defects due to the influence of analyst experience and subjective factors when manually analyzing CAE simulation results. After confirmation by the management personnel of the mold R&D department, secondary verification can be achieved to effectively improve the R&D efficiency.

[0096] In addition, the above step S7 also includes judging whether the mold design scheme is qualified according to the mold trial processing results, and sending the mold trial processing results to the mold R&D department: if the mold design scheme is unqualified, the mold trial processing data and the simulation analysis results are collected and input into the mold design scheme correction model, the mold design scheme is corrected to generate a corrected mold scheme, and the corrected corrected mold scheme and the mold design scheme, simulation analysis results and mold trial processing data are packaged and sent to the mold R&D department. Providing suggestions for the mold R&D department to further develop and optimize the mold design scheme will help the mold R&D project to be implemented quickly and with high quality.

[0097] Reference Figure 5 The method of obtaining the functional module inventory information, determining the missing functional modules according to the mold design plan, and generating manufacturing requirements and sending them to the mold manufacturing department for functional module manufacturing specifically includes the following steps:

[0098] D1. Determine the missing functional modules: obtain the functional module inventory information and determine the missing functional modules according to the mold design plan;

[0099] D2. Determine whether the missing functional modules include common modules;

[0100] D3. Generate manufacturing requirements: If they do not exist, generate manufacturing requirements based on the missing functional modules and send them to the mold manufacturing department;

[0101] D4. Calculate the recommended replenishment quantity of the general module: If it exists, obtain the historical call information of the general module with insufficient inventory, and calculate the recommended replenishment quantity of the general module through the preset replenishment recommendation formula;

[0102] D5. Generate manufacturing demand: Generate manufacturing demand based on the recommended replenishment quantity of the missing common modules and the demand quantity of the missing customized modules and send it to the mold manufacturing department.

[0103] The above supplementary recommended formula is as follows:

[0104] Y = max(x,z);

[0105] ;

[0106] Among them, Y is the recommended replenishment quantity of the general module, X is the missing quantity of the general module based on the module inventory situation; Z is the predicted optimal replenishment quantity; A is the call quantity of the general module within the unit R&D cycle, B is the average number of calls when the general module is scrapped, and C is the existing inventory quantity of the general module. Through the above steps, according to the inventory of the functional modules of the enterprise, the module missing situation of the mold design scheme is determined. Through modular splitting, the general modules in stock can be directly used, and only the missing customized modules need to be manufactured. When the general module inventory is insufficient, the historical call information of the missing general modules is used to calculate and analyze the optimal number of such modules required by the enterprise according to the actual situation, and the recommended replenishment quantity of such molds is determined according to the actual inventory relationship of the enterprise and the number of such modules required by the scheme, which can achieve efficient management of general mold inventory and ensure efficient verification of each mold design scheme.

[0107] For example, if the inventory of model A universal module required by the mold design plan is less than 3, then the optimal inventory quantity of the universal mold calculated based on the historical call information of model A universal module is 25, and the inventory quantity at this time is 17 (including those called by other projects), then the predicted optimal replenishment quantity Z is 8, and the recommended replenishment quantity of the universal module is 8, which not only meets the needs of the second verification, but also ensures the smooth progress of other scheme verification work. On the contrary, if the inventory quantity at this time is 24 (including those called by other projects), the predicted optimal replenishment quantity Z is 1, and the recommended replenishment quantity of the universal module is 3, which means that the inventory quantity of this type of module basically meets the call demand, and the insufficient inventory phenomenon is an emergency, and it is only necessary to manufacture to meet the needs of this method verification.

[0108] Reference Figure 6-Figure 8 The trial mold includes an upper mold plate 1, a lower mold plate 2 and multiple functional modules 3, and the multiple functional modules 3 are distributed and installed at the bottom of the upper mold plate 1 and the top of the lower mold plate 2; the upper mold plate 1 is spliced ​​by one or more upper mold base parts 11, and the lower mold plate 2 is spliced ​​by one or more lower mold base parts 21, and the cross-sectional shapes of the upper mold base parts 11 and the lower mold base parts 21 are both square or L-shaped. Through various specifications of square or L-shaped upper mold base parts 11 and lower mold base parts 21, the size requirements of the upper and lower mold plates 2 of various mold solutions can be spliced.

[0109] Reference Figure 6-Figure 8 , multiple installation grooves 4 are evenly spaced at the bottom of the upper mold base part 11 and the top of the lower mold base part 21, and multiple functional modules 3 are provided with one or more installation rods 31 at the bottom, and the spacing of multiple installation grooves 4 is consistent with the spacing of multiple installation rods 31; multiple installation grooves 4 are provided with fixing holes 41 at the bottom, and multiple installation rods 31 are provided with threaded grooves 32 at the bottom; when the functional module 3 is installed, the installation rod 31 is inserted into the installation groove 4, and the fixing bolt 42 is inserted into the end of the fixing hole 41 away from the installation groove 4. After tightening the fixing bolt 42, the tail of the fixing bolt 42 is threadedly connected with the threaded groove 32 at the bottom of the installation rod 31. Through the arrangement of the installation groove 4, the installation rod 31, the fixing hole 41 and the fixing bolt 42, the functional module 3 and the upper and lower templates 2 can be quickly and accurately installed, which is helpful for the rapid assembly of the trial mold and further improves the efficiency of research and development verification.

[0110] Reference Figure 6-Figure 8, the upper mold base part 11 and the lower mold base part 21 are both provided with a plurality of transverse connecting through holes 5 and a plurality of longitudinal connecting through holes 6 which are equidistantly opened in the transverse and longitudinal directions, and the transverse connecting through holes 5 and the longitudinal connecting through holes 6 on the same upper mold base part 11 or the lower mold base part 21 are stacked in the vertical direction and are not connected; a plurality of transverse connecting through holes 5 and the longitudinal connecting through holes 6 on the same axis of the upper mold plate 1 and the lower mold plate 2 are both penetrated by a connecting rod 7, one end of the connecting rod 7 is provided with a blocking block 71, and the other end is threadedly connected with a fixing block 72. Through the provision of a plurality of transverse connecting through holes 5 and a plurality of longitudinal connecting through holes 6, a stable connection between the upper mold base parts 11 and between the upper mold base parts 11 is achieved through the connection and fastening of the connecting rod 7, which is helpful for the rapid assembly of the trial mold and further improves the efficiency of R&D verification.

[0111] In addition, in order to further improve the connection stability between the upper mold base parts 11 and the lower mold base parts 21, a connection structure can be further set on the upper mold base parts 11 and the lower mold base parts 21, such as respectively setting a protrusion and a groove at both ends of the same direction of the upper mold base part 11, and the lower mold base part 21 is set similarly.
