[0002] In the design and manufacturing process of molds, process parameter labeling and expression are crucial, however, traditional two-dimensional (2D) drawings and labeling methods have some limitations, and it is difficult to completely and accurately show the complexity of mold design and the details of each process attribute. The manufacturing process of a mold usually includes multiple process parameters (such as surface roughness, heat treatment requirements, precision, material properties, etc.), which are often interrelated, and two-dimensional drawings are difficult to completely express these complex multi-dimensional information on a plane. In addition, the current mold industry process labeling has the problem of fragmentation of three-dimensional process data, and there is a lack of version tracking mechanism between different versions of 2D / 3D drawings. When the design is changed, the related process parameters need to be manually re-labeled, resulting in a version misalignment rate of 37% (industry research data). SUMMARY
[0003] The purpose of the present application is to provide a mold process attribute labeling method to address the shortcomings of the prior art. By combining two-dimensional engineering drawings and three-dimensional digital models with associated bubbles, multiple dimensions of process parameters such as machining precision, surface treatment, and material properties are effectively labeled and conveyed through bubble charts, improving communication efficiency between engineers and designers, reducing misunderstandings and communication costs, and solving the limitations of traditional two-dimensional labeling.

[0007] C. setting parameters for each associated bubble and generating an associated bubble set table.
[0008] A further improvement to the above solution is that the associated bubble includes a bubble identifier, which is a number and / or a letter and / or a word.
[0009] A further improvement to the above solution is that the associated bubble further includes a bubble pattern, which includes shape and / or color and / or size classification.
[0010] In the step B, when the associated bubble mark is made, a bubble pattern with a corresponding shape and / or color and / or size is selected according to the type of the process to make the mark.
[0011] Further improvement of the above scheme is that the associated bubble set table includes one or more categories of size chain reference, upper and lower tolerance band, geometric tolerance, machining allowance, tool parameter, cutting three elements, equipment type, tooling code, work time quota, detection item point, and surface integrity requirement.
[0012] Further improvement of the above scheme is that the associated bubble set table contains a dynamic calculation formula, and when the reference size is changed, the associated tolerance value is automatically updated.
[0013] Further improvement of the above scheme is that the associated bubble set table contains a version comparison function, which can display the parameter change track of the same machining feature in different versions of drawings.
[0014] Further improvement of the above scheme is that the step A further includes the following steps:
[0015] Draw the two-dimensional engineering drawing of the mold through the two-dimensional engineering drawing design software, save the completed two-dimensional engineering drawing of the mold in the DWG or DXF file format;
[0016] Construct a three-dimensional digital model of the mold through a three-dimensional modeling software, and export the completed three-dimensional digital model of the mold into a 3D WEB file format.
[0017] Further improvement of the above scheme is that the associated bubble set table is cross-file associated, automatically inherits the version information of the design file and records the identity of the marker.
[0018] Further improvement of the above scheme is that the bubble mark interface provides a screenshot comment function, supports multi-person collaborative marking, and generates a timestamped modification record.

[0023] C, respectively, each associated bubble parameter setting and generating associated bubble set table;
[0024] The mold process attribute marking method of the application combines two-dimensional engineering drawings and three-dimensional digital models of the mold through associated bubbles for combined marking, which not only effectively marks and conveys multiple dimensional process parameters such as machining precision, surface treatment, material properties, etc. through the bubble chart, improves the communication efficiency between engineers and designers, reduces misunderstanding and communication cost, but also better keeps two-dimensional engineering drawings and three-dimensional digital models simple and avoids redundancy, so as to make it easier to read the drawings and avoid errors, solving the limitations of traditional two-dimensional drawings. DETAILED DESCRIPTION
[0025] The mold process attribute marking method of the application comprises the following steps:
[0026] A, respectively, input two-dimensional engineering drawings and three-dimensional digital models of the mold;
[0027] B, respectively, mark associated bubbles at each key position in the two-dimensional engineering drawings and three-dimensional digital models of the mold; the key positions are generally key machining areas or relatively complex parts in design, such as hole positions, machining surfaces, mating surfaces, etc.; bubble data can include geometric dimensions: size chain reference, upper and lower tolerance band, geometric tolerance; process dimensions: machining allowance, tool parameters, cutting three elements; resource dimensions: equipment type, tooling code, work hour quota; quality dimensions: detection points, surface integrity requirements, etc.
[0028] C, respectively, each associated bubble parameter setting and generating associated bubble set table.
[0029] The mold process attribute marking method of the application combines two-dimensional engineering drawings and three-dimensional digital models of the mold through associated bubbles for combined marking, which not only effectively marks and conveys multiple dimensional process parameters such as machining precision, surface treatment, material properties, etc. through the bubble chart, improves the communication efficiency between engineers and designers, reduces misunderstanding and communication cost, but also better keeps two-dimensional engineering drawings and three-dimensional digital models simple and avoids redundancy, so as to make it easier to read the drawings and avoid errors, solving the limitations of traditional two-dimensional drawings.
[0030] The associated bubble comprises a bubble identifier, which is a number and / or a letter and / or a word; in this embodiment, numbers 1, 2, 3, etc. are used to identify and distinguish each associated bubble; of course, in other embodiments, letters A, B, C, etc. or Chinese characters, etc. can also be used to identify and distinguish each associated bubble.
[0031] The association bubble further comprises a bubble pattern, and the bubble pattern comprises shape and / or color and / or size classification;
[0032] In the step B, when the association bubble is marked, the bubble pattern with corresponding shape and / or color and / or size is selected according to the type of the process to mark; for example, a red bubble represents precision requirement, a green bubble represents surface treatment requirement, etc., by selecting bubbles with different colors, shapes and sizes according to the type of the process parameter to mark, the bubbles can be classified and marked more easily and quickly, and the efficiency is improved.
[0033] The association bubble set table comprises one or more types of size chain reference, upper and lower tolerance band, geometric tolerance, machining allowance, tool parameter, cutting three elements, equipment type, tooling code, work hour quota, detection item point and surface integrity requirement; compared with marking each process parameter beside the two-dimensional engineering drawing and the three-dimensional digital model of the mold, it is not only difficult to realize and easy to make mistakes, but also makes the two-dimensional engineering drawing and the three-dimensional digital model itself very redundant, which is very troublesome for the drawing personnel, the present application binds each process parameter with the association bubble and forms the association bubble set table, so that detailed process requirement description can be added to each bubble mark, which can be text description or link to specific process document, and the drawing personnel can clearly and quickly obtain the required data information.
[0034] Compared with manual synchronous updating of 2D / 3D marking when the design is changed, the association bubble set table of the present application comprises a dynamic calculation formula, when the reference size is changed, the associated tolerance value is automatically updated, which is more convenient and efficient, and can avoid errors.
[0035] The association bubble set table comprises a version comparison function, which can display the parameter change track of the same machining feature in different version drawings, and is easier to track and compare.
[0036] The step A further comprises the following steps:
[0037] The two-dimensional engineering drawing of the mold is drawn by a two-dimensional engineering drawing design software such as Zhongwang, AutoCAD, SolidWorks 2D, DraftSight, etc., and the completed two-dimensional engineering drawing of the mold is saved in DWG or DXF file format;
[0038] Through three-dimensional modeling software such as Zhikang, SolidWorks, CATIA, Pro / ENGINEER, Siemens NX, etc. The three-dimensional digital model of the mold is constructed, and the completed mold three-dimensional digital model is exported as a 3D WEB file format, which can maintain the three-dimensional effect of the model and has the functions of interaction such as rotation, scaling, etc. For example, introduce bubbles in the water cup process chart, first input the attribute data of each process of the water cup (which can be marked by the comment area), generate a 3D bubble chart, and then convert it into a 2D chart.
[0039] The associated bubble set table is cross-file associated, automatically inherits the version information of the design file and records the identity of the marker, which is more convenient for quality traceability, shortens the traceability time and improves the overall efficiency.
[0040] The bubble marking interface provides a screenshot comment function, supports multi-person collaborative marking and generates a timestamped modification record, which can reduce the communication level, better shorten the communication time and improve the overall efficiency.
[0041] A mold process attribute marking system, comprising a processor and a memory, the memory stores program modules, the program modules run on the processor, and realize a mold process attribute marking method as described above.
