[0049] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0050] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0051] like Figure 1 As shown, an embodiment of the present invention provides a control management method based on the entire process of mold development and design, and the method includes the following steps:

[0052] S100, receiving mold development requirement information and mold drawings, wherein the mold development requirement information includes a number of specific development requirements;

[0053] S200, analyzing the integrity of the mold drawing to generate drawing integrity information;

[0054] S300, inputting mold development demand information into a demand feature library to obtain a number of demand features, performing feature recognition on mold drawings based on the demand features, and generating demand compliance verification information;

[0055] S400, receiving mold measurement information, comparing and verifying the mold measurement information with the mold drawing, and generating material size inspection information;

[0056] S500, receiving mold inspection information, determining standard inspection requirements according to specific development needs, and generating reliability inspection information according to the mold inspection information and the standard inspection requirements.

[0057] It should be noted that drawing management is a key link in the mold development process. Traditionally, the integrity, accuracy and compliance inspection of drawings mainly rely on the experience and intuition of engineers, which often leads to missed inspections or misjudgments. At the same time, mold development demand information is usually communicated verbally or in simple document forms, lacking systematic and standardized management, which makes it easy for omissions or misunderstandings to occur during the transmission process. The embodiments of the present invention are intended to solve the above problems.

[0058] In an embodiment of the present invention, the user first needs to input mold development requirement information and mold drawings. The mold development requirement information includes several specific development requirements. Preferably, the mold drawings are three-dimensional drawings. Then, the integrity of the mold drawings will be analyzed to generate drawing integrity information to ensure the accuracy and completeness of the drawings, reduce manual intervention, improve management efficiency, and ensure that the mold can be manufactured and processed smoothly. Next, the mold development requirement information will be automatically input into the requirement feature library to obtain several requirement features to ensure that the requirements are not omitted or misunderstood during the transmission process, and that the requirement features can meet the corresponding specific development requirements. Based on the requirement features, the mold drawings are feature identified to determine whether the requirement features can all be found in the mold drawings, and requirement compliance verification information is generated to ensure that the mold drawings can meet user requirements. After the mold manufacturing is completed, it is necessary to measure and obtain the mold measurement information, compare and verify the mold measurement information with the mold drawing, and generate material size inspection information; the mold will also be tested for reliability items to obtain mold inspection information, and the standard inspection requirements will be determined according to the specific development needs. Reliability inspection information is generated based on the mold inspection information and standard inspection requirements. In this way, strict control and management of the entire mold development process can be achieved to ensure the stability and consistency of mold quality.

[0059] like Figure 2 As shown, as a preferred embodiment of the present invention, the steps of analyzing the integrity of the mold drawing and generating the drawing integrity information specifically include:

[0060] S201, identifying each component in the mold drawing, determining whether the material of each component is clear, and obtaining the material integrity;

[0061] S202, determine whether the dimension markings of each component are clear, obtain the dimensional integrity, obtain the drawing integrity information based on the material integrity and dimensional integrity, and K2 is a fixed value set in advance.

[0062] Specifically, determine whether the dimension markings of each component are clear, obtain the dimensional integrity, and obtain the drawing integrity information based on the material integrity and dimensional integrity. The specific steps are as follows:

[0063] By identifying each component in the mold drawing, the total number of components in the mold drawing and the material weight of the components are obtained. Based on the total number of components in the mold drawing and the material weight of the components, the material integrity is obtained. The relationship between the corresponding process is:

[0064]

[0065] Among them, A represents the material integrity, M i represents the material integrity of the i-th component, represents the material weight of the i-th component, and n represents the total number of components in the mold drawing;

[0066] By determining the dimensioning of each component, the total number of dimensioned components and the dimension weight of the component are obtained, and the dimensional integrity is obtained by using the total number of dimensioned components and the dimension weight of the component. The relationship between the corresponding process is:

[0067]

[0068] Where B represents dimensional integrity, m represents the total number of dimensioned parts, and D j represents the dimensional integrity of the jth component, represents the size weight of the jth component;

[0069] Based on the material integrity and size integrity, the drawing integrity information is obtained. The relationship between the corresponding process is:

[0070] C=α A A+α B B;

[0071] Among them, C represents the drawing integrity information, α A The weight coefficient representing the material integrity, α B A weight factor indicating dimensional integrity.

[0072] Furthermore, normalization is used to make the calculation results have good comparability and consistency, and can maintain stability in data of different ranges; the present invention introduces weight coefficients of different data to have scalability and dynamic adjustment capabilities to adapt to the ever-changing extended analysis.

[0073] In the embodiment of the present invention, in order to ensure the accuracy and completeness of the drawings, each component in the mold drawing is automatically identified, it is determined whether the material of each component is clear, and the material integrity is calculated, which is = the number of components with clear material markings / the total number of components. It is also determined whether the dimension markings of each component are clear, and the dimension integrity is obtained, which is = the number of components with clear dimension markings / the total number of components. The condition is met only when the drawing integrity is 100%.

[0074] like Figure 3 As shown, as a preferred embodiment of the present invention, the step of inputting mold development requirement information into a requirement feature library to obtain a plurality of requirement features specifically includes:

[0075] S301, inputting mold development requirement information into a requirement feature library, so that a number of specific development requirements are matched one by one with the feature information in the requirement feature library;

[0076] S302, outputting the matched feature information, and removing duplicate features from all the output feature information to obtain a number of required features.

[0077] In the embodiment of the present invention, in order to match the specific development requirements with the requirement characteristics, it is necessary to build a requirement characteristic library in advance, and the requirement characteristic library contains a large number of specific development requirements, and each specific development requirement corresponds to one or more characteristic information. Inputting the mold development requirement information into the requirement characteristic library will automatically match a number of specific development requirements with the characteristic information in the requirement characteristic library one by one, and then automatically output the matching characteristic information. It is easy to understand that some characteristic information will appear repeatedly, and finally all the output characteristic information will be deleted for repeated characteristics, and a number of requirement characteristics will be obtained.

[0078] like Figure 3 As shown, as a preferred embodiment of the present invention, the step of performing feature recognition on the mold drawing based on the requirement features and generating the requirement compliance verification information specifically includes:

[0079] S303, retrieving the local special features of each required feature, performing feature recognition on the mold drawing based on the local special features, and determining a feature area in the mold drawing containing the local special features;

[0080] S304, matching and verifying the feature area with the required feature to determine whether the mold drawing contains the required feature;

[0081] S305, generating demand compliance verification information based on the successful identification of a number of demand features.

[0082] Specifically, the feature area is matched and verified with the required feature to determine whether the mold drawing contains the required feature. The specific steps are as follows:

[0083] The basic weight of the demand feature is obtained based on the local special features of the demand feature, and the matching reliability coefficient of the demand feature is obtained in the process of matching and verifying the feature area with the demand feature;

[0084] The weight correction value of the demand feature is obtained by using the basic weight of the demand feature and the matching reliability coefficient of the demand feature. The corresponding process has the following relationship:

[0085] W k =L k ·(1+λ k ·C k );

[0086] Among them, W k represents the weight correction value of the kth demand feature, L k represents the basic weight of the kth demand feature, λk represents the complexity factor of the kth requirement feature, C k represents the matching reliability coefficient of the kth demand feature;

[0087] The weighted sum of the weight correction values ​​of the demand characteristics is performed to obtain the overall matching score of the demand characteristics. The corresponding relationship in the process is:

[0088]

[0089] Among them, M represents the overall matching score of the demand features, K represents the total number of demand features, and S k Indicates the matching status of the kth requirement feature;

[0090] The normalization factor of the demand characteristics is obtained based on the weight correction value of the demand characteristics. The corresponding process has the following relationship:

[0091]

[0092] Where T represents the normalization factor of demand characteristics;

[0093] The demand matching degree is obtained by using the overall matching score of the demand characteristics and the normalization factor of the demand characteristics. The corresponding relationship in the process is:

[0094]

[0095] Among them, R represents the demand matching degree, and β represents the overall adjustment coefficient;

[0096] The requirement matching degree is used to determine whether the mold drawing contains the requirement features.

[0097] Furthermore, the present invention can comprehensively reflect the overall compliance status of the mold drawings by introducing multiple factors such as the basic weights of the matching status and demand characteristics; the present invention facilitates actual calculations and can provide rich information, and is suitable for use in the optimization system.

[0098] In an embodiment of the present invention, in the demand feature library, each feature information is correspondingly provided with a local special feature, and the local special feature is preferably an uncommon shape feature. Before identification, the local special feature of each demand feature is automatically retrieved, and then the mold drawing is feature identified based on the local special feature to determine the feature area of ​​the mold drawing containing the local special feature, and then the feature area is matched and verified with the demand feature, for example, similarity calculation is performed to determine whether the mold drawing contains the demand feature. When the similarity is higher than the similarity threshold, it is determined that the mold drawing contains the demand feature. Finally, according to the successful identification of several demand features, demand compliance verification information is generated. Only when all demand features are successfully identified, the demand compliance verification information is qualified, otherwise it is unqualified.

[0099] like Figure 4 As shown, as a preferred embodiment of the present invention, the step of determining the standard inspection requirements according to the specific development requirements and generating reliability inspection information according to the mold inspection information and the standard inspection requirements specifically includes:

[0100] S501, inputting the specific development requirements into the requirements standard inspection library to obtain standard inspection requirements, wherein the standard inspection requirements include a number of inspection items, each of which corresponds to qualified data;

[0101] S502, comparing the mold inspection information with the standard inspection requirements, determining whether the mold inspection information includes all inspection items and all inspection items are qualified, and generating reliability inspection information.

[0102] Specifically, the mold inspection information is compared with the standard inspection requirements to determine whether the mold inspection information contains all inspection items and all inspection items are qualified, and reliability inspection information is generated. The specific steps are as follows:

[0103] The qualified status of the inspection items is obtained by comparing the mold inspection information with the standard inspection requirements. At the same time, the weighted inspection qualified rate is obtained by combining the total number of items involved in the inspection. The corresponding relationship in the process is:

[0104]

[0105] Among them, S represents the weighted inspection pass rate, T represents the total number of items involved in the inspection, and δ t represents the qualified status of the tth inspection item, γ t represents the weight of the tth test item;

[0106] The number of untested items is obtained, and the penalty factor of the untested items is calculated by the number of untested items. The relationship between the corresponding process is:

[0107]

[0108] Among them, P represents the penalty factor of untested items, V represents the number of untested items, and exp(·) represents the exponential function processing;

[0109] Combining the weighted inspection pass rate with the penalty factor of the uninspected items, the reliability inspection information is obtained. The corresponding process relationship is:

[0110] Q = S·P;

[0111] Wherein, Q represents reliability verification information.

[0112] Furthermore, the present invention introduces a nonlinear penalty mechanism to enable higher sensitivity and adjustment capability in extreme cases; the present invention is concise in design, convenient for actual calculation, and also convenient for rapid interpretation and analysis of results.

[0113] In the embodiment of the present invention, a demand standard inspection library is also established in advance, and the demand standard inspection library contains a large number of specific development requirements, and each specific development requirement corresponds to an experimental inspection standard. In this way, by inputting the specific development requirements into the demand standard inspection library, the standard inspection requirements will be automatically obtained, and the standard inspection requirements will include several inspection items, and each inspection item will correspond to qualified data; then the mold inspection information is compared with the standard inspection requirements to determine whether the mold inspection information contains all the inspection items, and only when all the inspection items are qualified, will the reliability inspection information be generated.
