Description

Technical Field

[0001] The present invention relates to the technical field of mold manufacturing management, and specifically, to a mold manufacturing management system for reducing the design cycle. Background Art

[0002] Mold design is a key link connecting product design and production in the manufacturing industry, involving core contents such as digital modeling, process planning, and mold structure optimization.

[0003] In the process of industrial mold design, for the mold design of the same enterprise or the same type of enterprises, since the mold application products are generally the same and there are only minor differences in most cases, most of the mold areas will use the data of historical molds for design. The traditional mold design is mainly carried out through the following steps:

[0004] First, obtain the application product of the current mold, that is, the material and forming structure of the application product, etc.

[0005] Second, when the current mold is similar to the historical mold, generally follow the design route of the historical mold for route planning, such as the design sequence of each forming area and the allowance value reserved for different areas.

[0006] Third, carry out mold design according to the matched route, and verify the finished product data of the designed mold, such as verifying data such as whether there are burrs, whether the formed product meets the use standard, and whether it can be formed smoothly.

[0007] Fourth, analyze in combination with the verified data. When the above problems occur in the finished product, perform secondary design on the previously reserved allowance value, that is, perform secondary design by decreasing the allowance value, and continue to perform finished product verification until the finished product data standard is reached.

[0008] In the above steps, since the decreasing amount used in the traditional secondary design of the allowance value is referenced from historical data, and the acquisition of historical data is through matching prediction, it is very easy to change due to the forming area structure type of the mold and the finished product material, resulting in the difficulty of adapting the decreasing allowance value in the historical data, increasing the number of times of the entire secondary design, and even failing to reach the finished product data before the allowance is decreased, resulting in a decrease in the stability of the final design cycle and a significant increase in the design cycle.

[0009] In order to address the above problems, there is an urgent need for a mold manufacturing management system for reducing the design cycle. Summary of the Invention

[0010] The purpose of the present invention is to provide a mold manufacturing management system for reducing the design cycle to solve the problems raised in the above background art.

[0011] To achieve the above object, a die manufacturing management system for reducing the design cycle is provided, including a product shape analysis module and a die forming structure matching module. The product shape analysis module is used to collect the shape structure data of the production product as a reference for subsequent die design. The die forming structure matching module combines the shape structure data of the production product to obtain the forming items of the adapted die. It also includes a historical die design data storage module, a route planning module, and a die design error analysis module;

[0012] Among them, the historical die design data storage module is used to collect the overall design process of the historical die, obtain the processing items of the entire design cycle, and establish a historical die database for storing the processing items;

[0013] The route planning module combines the processing items to plan the design route and error verification route of the current die;

[0014] The die design error analysis module obtains the finished product data of the die design and compares it with the actual design requirements to determine whether there is an error;

[0015] When there is no error in the finished product data of the die design, the current die is directly used as the design result;

[0016] When there is an error in the finished product data of the die design, error adjustment is performed according to the error verification route planned by the route planning module to obtain the die data after error adjustment, and the finished product is designed according to the die data after error adjustment to obtain the finished product data of the die design after adjustment, and it is compared with the finished product data of the die design after historical adjustment;

[0017] When the finished product data of the die design after adjustment is better than the finished product data of the die design after historical adjustment, the die designed by the above error verification route is used as the design result;

[0018] When the finished product data of the die design after adjustment is worse than the finished product data of the die design after historical adjustment, processing item adjustment is performed to obtain a secondary planned error verification route, marked as an updated error verification route, until an updated error verification route matching the finished product data better than the die design after historical adjustment is obtained, and the historical die database is updated.

[0019] As a further improvement of this technical solution, the forming items in the product shape analysis module include application materials, forming area structure types, and adjacent area connection nodes;

[0020] The application material is the material of the product formed by the current die;

[0021] The forming area structure type is the structural construction of the product formed by the die;

[0022] The adjacent region connection node is the connection region between adjacent forming regions.

[0023] As a further improvement of this technical solution, the processing items in the historical mold design data storage module include the forming area design sequence, design margin mark, design margin decrement, and decrement verification result feedback;

[0024] Among them, the forming area design sequence is the design sequence between different forming areas;

[0025] The design margin mark is the design margin reserved in advance to reduce design errors during the design process;

[0026] The design margin decrement is the unit margin decrement set after an error is verified;

[0027] The decrement verification result feedback is the verification result after each unit margin decrement.

[0028] As a further improvement of this technical solution, the route planning module includes a design route planning unit and an error verification route planning unit;

[0029] Among them, the design route planning unit combines the forming area design sequence in the historical mold design data storage module, obtains a historical mold of the same type as the forming area of the current design mold, and formulates a corresponding design route according to the corresponding forming area design sequence;

[0030] The error verification route planning unit collects verification data of the product produced after the mold design is completed, and in response to the product error, formulates an error verification route in combination with the design margin mark and the design margin decrement in the historical mold design data storage module.

[0031] As a further improvement of this technical solution, the method for formulating a corresponding design route according to the corresponding forming area design sequence in the design route planning unit includes the following steps:

[0032] S4101. Obtain the structures of each forming area in the historical mold and classify them according to the design difficulty;

[0033] S4102. Combine the historical mold results, obtain the optimal design sequence between different types of forming areas, and mark the corresponding forming area types and the connection nodes between adjacent forming areas;

[0034] S4103. Obtain the forming area structure type and adjacent region connection node of the current mold, and match them with the forming area type and the connection node between adjacent forming areas in step S4102;

[0035] S4104. Obtain the design route of the current mold according to the matching result.

[0036] As a further improvement of this technical solution, the method for formulating the error verification route in the error verification route planning unit includes the following steps:

[0037] S4201. Combine the matching result in S4103 to obtain the historical mold error verification data matched by the current mold;

[0038] S4202. Formulate the error design route of the current mold according to the historical mold error verification data.

[0039] As a further improvement of this technical solution, the method for obtaining the error verification route of quadratic programming in the mold design error analysis module includes the following steps:

[0040] S5101. Combine the design margin decrement in the error verification route to formulate the quadratic unit decrement ;

[0041] Among them, the quadratic unit decrement includes an increasing trend and a decreasing trend. The quadratic unit decrement in the increasing trend is the design margin decrement + the supplementary amount , and the quadratic unit decrement in the decreasing trend is - the supplementary amount ;

[0042] S5102. Obtain the real-time verification results in the increasing trend and the decreasing trend, and compare them with the finished product data of the mold design to obtain the number of times the quadratic unit decrement is consumed when exceeding the finished product data of the mold design in both trends;

[0043] S5103. Mark the trend with fewer times of consuming the quadratic unit decrement as the best trend, and obtain the corresponding final margin = initial design margin - quadratic unit decrement × number of consumption times.

[0044] As a further improvement of this technical solution, the method for obtaining the supplementary amount in S5101 includes the following steps:

[0045] S51011. Verify the finished product data of the initial margin of each mold material, and use the current finished product data as the basis for comparison;

[0046] S51012. Perform a decrement process on the initial margin to obtain the decremented finished product data after decrement, and compare it with the finished product data of the initial margin;

[0047] When there is a difference between the two, the decreasing amount is reduced, and the initial remaining amount is decreased again according to the reduced decreasing amount. The decreased finished product data after the decrease is obtained again and compared with the finished product data of the initial remaining amount.

[0048] When there is no difference between the two, the corresponding reduced decreasing amount is marked as the supplementary amount of the current mold material. ;

[0049] S51013. Mark the supplementary amount corresponding to the application material of each mold as historical verification data, and store the historical verification data in the historical mold database.

[0064] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0065] Please refer to Figure 1-2 As shown, a mold manufacturing management system for reducing the design cycle is provided, including a product shape analysis module 10 and a mold forming structure matching module 20. The product shape analysis module 10 collects the shape structure data of the production product;

[0066] In order to ensure the continuity of the overall design cycle, it is necessary to ensure the sequential progress of the entire cycle. Through the mold forming structure matching module 20 combined with the shape structure data of the production product, the forming items of the adapted mold are obtained, that is, including the application material, the structure type of the forming area, and the connection nodes of adjacent areas. Among them, the application material is the material of the currently molded product of the mold. For example, the molding of a plastic product; the structure type of the forming area is the structural construction of the molded product of the mold, such as columnar, spherical, and square structures, which is designed according to the shape of the final molded product; the connection nodes of adjacent areas are the connection areas between adjacent forming areas. For example, for a molded product with an I-shaped structure, it includes two square-shaped forming areas and a columnar structure connecting the two areas. Among them, the columnar structure is the connection area between adjacent forming areas and serves as a reference basis for subsequent mold design.

[0067] In order to reduce the design cycle and improve the efficiency of the overall mold design, this solution further includes a historical mold design data storage module 30, a route planning module 40, and a mold design error analysis module 50;

[0068] Among them, the historical mold design data storage module 30 collects the overall design process of historical molds, obtains the processing items of the entire design cycle, and establishes a historical mold database for storing the processing items. The processing items of the entire design cycle include the design sequence of the forming area, the design margin mark, the design margin decrement, and the feedback of the decrement verification result. The design sequence of the forming area is the design sequence between different forming areas. For example, a mold includes four forming areas, namely Area I, Area II, Area III, and Area IV. During the design process, when the design sequence is Area III - Area IV - Area II - Area I, this design sequence is the optimal design sequence. It should be noted that the optimal design sequence here refers to the fastest design cycle for designing the current forming area according to the above design sequence;

[0069] The design margin mark is the design margin reserved in advance during the design process to reduce design errors. For example, the thickness of the connection area between adjacent forming areas is increased by one millimeter on the original design amount to ensure later verification. This is because during the mold design process, in order to avoid differences between the currently designed data and the actual estimated values, a margin is reserved in specific areas in advance to provide a modification space for errors that may occur later;

[0070] The design margin decrement is the unit margin decrement set after an error is verified. That is, after an error is verified, the thickness of the original area is decreased by one unit thickness, and a secondary verification is performed after the decrement;

[0071] The feedback of the decrement verification result is the verification result after each unit margin decrement. That is, the finished product verification is performed on the designed finished product, including verifying data such as the forming effect of the formed product, whether burrs appear, and whether it is fully formed;

[0072] The route planning module 40 includes a design route planning unit 410 and an error verification route planning unit 420. Among them, the design route planning unit 410 combines the design sequence of the forming area in the historical mold design data storage module 30, obtains historical molds of the same type as the corresponding forming area of the currently designed mold, and formulates a corresponding design route according to the corresponding design sequence of the forming area. As Figure 3 shown, the specific steps are as follows:

[0073] First, obtain the structures of each forming area in the historical mold and classify them according to the design difficulty. For example, for a regular polygon, its design difficulty is relatively low, and for an irregular forming area, the corresponding design difficulty is high. The types of each forming area are divided according to the design difficulty, and the time periods are divided in combination with the historical design time;

[0074] Secondly, in combination with the historical mold results, obtain the optimal design sequence between different types of forming areas, and mark the corresponding forming area types and the connection nodes between adjacent forming areas. Mark the types of connection nodes and the connected forming areas as a reference basis for later matching;

[0075] Finally, obtain the forming area structure type of the current mold and the connection nodes of adjacent areas, and match them with the forming area types and the connection nodes between adjacent forming areas. Use the design route corresponding to the successfully matched historical mold as the design route of the current mold, and perform forming area design according to the above design route.

[0076] The error verification route planning unit 420 collects the verification data of the product produced after the mold design is completed, and in response to the product error, formulates an error verification route in combination with the design margin mark and the design margin reduction amount stored in the historical mold design data storage module 30, as Figure 4 shown. The specific method is as follows:

[0077] First, in combination with the matching results above, obtain the historical mold error verification data matched by the current mold, and formulate the error design route of the current mold according to the historical mold error verification data. When an error occurs in the designed finished product, at this time, because the current mold has reserved a design margin in advance, in the actual verification process, it is necessary to adjust the design margin, and obtain the adjusted finished product data for comparison. Among them, the adjustment method is to gradually decrease according to the design margin reduction amount in the structurally matched historical mold. For example, the design margin of the current error mold is and the corresponding design margin reduction amount for matching is Therefore, the first adjusted design margin is and the second design margin is and so on for the design margin calculation.

[0078] The mold design error analysis module 50 obtains the finished product data of the mold design, and compares it with the actual design requirements to determine whether an error occurs;

[0079] When there is no error in the finished product data of the mold design, directly use the current mold as the design result;

[0080] When an error occurs in the finished product data of the mold design, perform error adjustment according to the error verification route planned by the route planning module 40, obtain the mold data after error adjustment, and design the finished product according to the mold data after error adjustment. Obtain the finished product data of the adjusted mold design, and compare it with the finished product data of the historically adjusted mold design;

[0081] When the finished product data of the adjusted die design is better than that of the historical adjusted die design, the die designed by the above error verification route is used as the design result;

[0082] When the finished product data of the adjusted die design is worse than that of the historical adjusted die design, the processing item is adjusted to obtain the error verification route of quadratic programming, marked as the updated error verification route, until the updated error verification route matching the finished product data better than the historical adjusted die design is obtained, and the historical die database is updated;

[0083] Such as Figure 5 shown, the method for obtaining the error verification route of quadratic programming includes the following steps:

[0084] First, it is necessary to formulate a quadratic unit decrement by combining the design margin decrement in the error verification route , since the actual error cannot be determined, two trends are defined in the present invention, namely the increasing trend and the decreasing trend. The quadratic unit decrement in the increasing trend is the design margin decrement + the supplementary amount , and the quadratic unit decrement in the decreasing trend is the design margin decrement - the supplementary amount , as Figure 6 shown, where the determination of the supplementary amount is to obtain historical verification data by combining the application materials of the current die, verify the finished product data of the initial margin of each die material, use the current finished product data as the basis for comparison, and perform a decrement process on the initial margin to obtain the decremented finished product data after decrement, and compare it with the finished product data of the initial margin;

[0085] When there is a difference between the two, the decrement is reduced, and the initial margin is decremented again according to the reduced decrement, and the decremented finished product data after decrement is obtained again and compared with the finished product data of the initial margin;

[0086] When there is no difference between the two, the corresponding reduced decrement is marked as the supplementary amount of the current die material , for example, in the actual detection process, when verifying the error of the finished product of material A, first determine the finished product data of the initial margin. Here, the finished product data is the qualified design data. At this time, the initial margin is decremented , and the finished product data after the margin is decremented is obtained and compared with the initial finished product data. If there is a difference, then reduce , repeat the above steps until there is no difference. At this time, the reduced is the supplementary amount ;

[0087] After the supplementary amount is completed After the determination, obtain the real-time verification results in the increasing trend and the decreasing trend, and compare them with the finished product data of the mold design to obtain the secondary unit decrement consumed when exceeding the finished product data of the mold design in both trends. The number of times, and the secondary unit decrement consumed The trend with fewer times is marked as the best trend. For example, the increasing trend consumes 3 times of secondary unit decrement to meet the finished product requirements, while the decreasing trend only consumes 2 times of secondary unit decrement to meet the finished product requirements. At this time, the corresponding decreasing trend is the best trend, and the corresponding final margin = initial design margin - secondary unit decrement × the number of consumption times, so as to realize the automatic update of the error verification route.

[0088] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
