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] During the industrial mold design process, for the mold design process of the same enterprise or the same type of enterprises, since the mold application products are generally the same and there are only slight differences in most cases, the data of historical molds are used for design in most areas of most molds. Traditional mold design is mainly carried out through the following steps: First, obtain the application product of the current mold, that is, the material and forming structure of the application product, etc.; 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 reserved allowance value of different areas; 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; 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 verify the finished product until the finished product data standard is reached.

[0004] 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 easily changed 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.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the 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.

[0019] Please refer to Figure 1-2As shown, a die manufacturing management system for reducing the design cycle is provided, including a product shape analysis module 10 and a die forming structure matching module 20. The product shape analysis module 10 collects the shape structure data of the produced product; To ensure the continuity of the overall design cycle, it is necessary to ensure the sequential progress of the entire cycle. Through the die forming structure matching module 20, combined with the shape structure data of the produced product, the forming items of the adapted die are obtained, that is, including the applied material, the structure type of the forming area, and the connection nodes of adjacent areas. Among them, the applied material is the material of the currently die-formed product, such as the forming of a plastic product; the structure type of the forming area is the structural construction of the die-formed product, such as columnar, spherical, and square structures, which are designed according to the shape of the final formed product; the connection nodes of adjacent areas are the connection areas between adjacent forming areas. For example, for a formed product with an I-shaped structure, it includes two square-shaped forming areas and a columnar structure connecting the two areas. The columnar structure is the connection area between adjacent forming areas and serves as a reference basis for subsequent die design.

[0020] To reduce the design cycle and improve the efficiency of the overall die design, this solution also includes a historical die design data storage module 30, a route planning module 40, and a die design error analysis module 50; Among them, the historical die design data storage module 30 collects the overall design process of historical dies, obtains the processing items of the entire design cycle, and establishes a historical die 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 die 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; 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 a unit millimeter on the original design amount to ensure subsequent verification. This is because during the die design process, in order to avoid differences between the currently designed data and the actual estimated values, a margin is reserved in advance in specific areas to provide a modification space for errors that may occur later; 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 a unit thickness, and a secondary verification is performed after the decrement; The decreasing verification result feedback is the verification result after each unit margin decrease, that is, the finished product verification is carried out on the finished products produced by the design, including verifying data such as the forming effect of the formed product, whether burrs appear, and whether it is fully formed; The route planning module 40 includes a design route planning unit 410 and an error verification route planning unit 420. The design route planning unit 410 combines the forming area design sequence in the historical mold design data storage module 30, obtains the historical mold of the same type as the forming area of the current design mold, and formulates the corresponding design route according to the corresponding forming area design sequence. For example, Figure 3 as shown below, the specific steps are as follows: First, obtain the structures of each forming area in the historical mold and classify them according to the design difficulty. For example, for regular polygons, the design difficulty is relatively low, and for irregular forming areas, the corresponding design difficulty is high. The types of each forming area are divided according to the design difficulty, and the time period is divided in combination with the historical design time; Secondly, 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. Mark the types of the connection nodes and the connected forming areas as the reference basis for later matching; Finally, obtain the forming area structure type of the current mold and the connection nodes of adjacent areas, match them with the forming area type 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 carry out the forming area design according to the above design route.

[0021] The error verification route planning unit 420 collects the verification data of the products produced after the mold design is completed, responds to the product error, and formulates an error verification route in combination with the design margin mark and the design margin decrease amount in the historical mold design data storage module 30. For example, Figure 4 as shown below, the specific method is as follows: First, combine the matching results above, obtain the error verification data of the historical mold 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 appears 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. The adjustment method is to sequentially decrease according to the design margin decrease amount in the structurally matched historical mold. For example, the design margin of the current error mold is , and the corresponding design margin decrease amount for matching is , so the first adjusted design margin is , and the second design margin is , and so on for the design margin calculation.

[0022] The mold design error analysis module 50 obtains the finished product data of the mold design, compares it with the actual design requirements, and determines whether there is an error. When there is no error in the finished product data of the mold design, the current mold is directly used as the design result. When there is an error in the finished product data of the mold design, error adjustment is performed according to the error verification route planned by the route planning module 40, the mold data after error adjustment is obtained, and the finished product is designed according to the mold data after error adjustment, the finished product data of the mold design after adjustment is obtained, and compared with the historical finished product data of the mold design after adjustment. When the finished product data of the mold design after adjustment is better than the historical finished product data of the mold design after adjustment, the mold designed by the above error verification route is used as the design result. When the finished product data of the mold design after adjustment is worse than the historical finished product data of the mold design after adjustment, the processing item is adjusted, the error verification route of the secondary planning is obtained, marked as the updated error verification route, until the updated error verification route matching the historical finished product data of the mold design after adjustment is obtained, and the historical mold database is updated. As Figure 5 shown, the method for obtaining the error verification route of the secondary planning includes the following steps: First, it is necessary to formulate a secondary unit decrement in combination with 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 secondary unit decrement in the increasing trend is the design margin decrement + the supplementary amount. , and the secondary unit decrement in the decreasing trend is - the supplementary amount. As Figure 6 shown, where the supplementary amount is determined by combining the application materials of the current mold, obtaining historical verification data, verifying the finished product data of the initial margin of each mold material, using the current finished product data as the basis for comparison, and performing a decrement process on the initial margin to obtain the decremented finished product data after decrement, and comparing it with the finished product data of the initial margin. 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. When there is no difference between the two, the corresponding reduced decrement is marked as the supplementary amount of the current mold material. , for example, during 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, decrement the initial margin , and obtain the finished product data after the margin is decremented, and compare it 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 ; After determining the supplementary amount , obtain the real-time verification results in the increasing trend and the decreasing trend, and compare them with the finished product data designed by the mold. Obtain the number of times of the secondary unit decrement consumed when exceeding the finished product data designed by the mold in both trends , and mark the trend with fewer times of consuming the secondary unit decrement as the best trend. For example, the increasing trend consumes 3 times of the secondary unit decrement to meet the finished product requirements, while the decreasing trend only consumes 2 times of the 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 × number of consumption times, so as to realize the automatic update of the error verification route.
