Detailed description of the invention
Fig. 1 is the design implementation method flow diagram of the work mold insert of the embodiment of the present invention.
Specific embodiment
With reference to the accompanying drawing and the embodiment of the present invention is described in further detail method of the invention.
Fig. 1 is the design implementation method flow diagram of the work mold insert of the embodiment of the present invention.As shown in Figure 1, the work
The design implementation method of mold insert, mainly includes the following steps:
Step 101: tablet pattern element, relevant parameter.
Here, the graphic element, relevant parameter, comprising: deburring, shaping etc. collect (FS), waste knife line (LSC), draw
Prolong shrinkage front (CBD), product week tangent line (CCP), preceding process profile (SFP) and main body frame type (WPName) etc..
Step 102: carrying out feature extraction, obtain the graphical-set for meeting insert computation rule.Detailed process are as follows: according to insert
Correlation, the generality of spatial distribution of design rule carry out feature extraction to original figure, are computed regular calculating, can
All figures or element classification that can relate to are output in graphical-set.
Step 103: differential process being carried out to the graphical-set, is obtained convenient for the graphical-set of the point, finite element that describe.Specifically
Process are as follows: differential process is carried out by classification to the graphical-set.For example, after curve is carried out differential process, if obtain doing
Set；The set of several finite elements (triangle or quadrangle) is obtained after curved surface is carried out differential process.
Step 104: sampling calculating being carried out according to insert design rule, obtains the graphical-set for meeting characteristic condition.Specifically:
By higher level gather in space coordinate, curvature and its derivative etc. of object substitute into the series established according to insert design rule, feature
In mathematical model, excludes without solution or the case where non-optimal solution, optimum solution is output in set.The characteristic condition of meeting
Feature set, including insert divide feature set, insert Cover Characteristics collection, insert operating characteristic collection etc..
Preferably, further comprising step 111 after step 104: carrying out correlation interactive computing, obtain and insert meter
Related node is calculated, then executes step 105 again.Specifically: according to the factors such as logic rules and spatial position distribution, retrieval
And several nodes related with insert are analyzed, detecting size calculates weight, if reaching certain standard, classifies by the rule of correspondence
Label.The related node refers to and calculates other nodes related, but do not obtained by this process with insert；It is described its
His node, such as other parts, figure, parameter.
Step 105: carrying out shape, position calculating, obtain the disaggregation for meeting constraint condition, parameter, spy needed for instantiating insert
The set such as sign, figure.Specifically: higher level's output is fallen into a trap by the corresponding mathematical model for being updated to different classifications and level of its classification
It calculates, according to different initial solutions, through different search, propagates scheduling algorithm combination, obtain the disaggregation for meeting constraint condition.
Step 106: carrying out interaction process before example.It specifically includes: being exported by higher level and carry out the calculating of insert dummy model, be
The assignment such as alternative features, tool characteristics.The feature is interacted by mold design logic and space shape, position etc. with other components.
Step 107: whether mutually disjunctive form position relationship meets design standard between judging part, if it is, executing step
Rapid 108；Otherwise, step 112 is executed.
Step 108: the set of parameter needed for exporting standard compliant instantiation, feature, figure etc..Specifically: output
The collection such as parameter, feature, figure needed for meeting (including what is met after amendment) instantiation of design standard.
Step 109: carrying out instantiation processing, obtain the result of visual insert scheme, assembly etc..Specifically: according to upper
The collection such as parameter needed for stating the instantiation of output, feature, figure, driving design software generates visual inserting module, described
Inserting module includes its relevant modifications feature, entity.
Step 110: carrying out interaction process after example, obtain final insert scheme and its correlated characteristic, figure, body, tree-shaped
Figure leaf node etc..Specifically: insert ontology and its decorative features after instantiation carry out cloth between other relevant components
The operations such as your operation, promotion and demotion, feature transfer, node transfer, integrated part is answered in fusion, and explicit nodes tree is made to meet one
As mold design habit.
Step 112: retrieving and mark the interdependent node for not meeting data, and date back node of problems and repaired
It is positive to calculate, it then returns again to execution step 107 and is judged again.
During the design of work mold insert of the embodiment of the present invention is realized, the classification of feature set is ubiquitous, each level
Element or the solution of output much will be by sorting out to different concentrations, just step utilizes convenient for after.The classification side of being related to
Method is more, common application, such as presses rule, presses decision tree, Bayesian Classification Arithmetic, neural network.To different problems, classification
The level of application of method is deep mixed, and specific method constitutes also different.
The design implementation method of the work mold insert of the embodiment of the present invention, there is following features:
1) it does not need manually to go to identify and design calculating, inserting module designs program can be according to different inputs, by one
Serial mathematical model calculates, insert needed for automatically generating mold, and determines its positional relationship.
The randomness that design is originally inputted is adapted to, each step algorithm has stronger adaptability, and special macro and sampling are calculated
Method universality is strong.For example, the feature set for classification extracted, is to obtain under certain mathematical model by a large amount of operations
, and this calculating (and based on derived from this calculating) is most scenes suitable for mold design.
The complexity of design environment is adapted to, is not only inserting module in space, there are also a lot of other components, examples
Such as: muscle, screw, main body all have indivisible relationship with inserting module, at this moment to be judged by series of computation, be obtained
There is the association (or conflict) in logic or morpheme between which components, because other are related to inserting module or zero conflict
Part is also to change with input variation, itself namely random to algorithm, so calculating, the method for retrieval, judgement
There is universality.The adaptability of single mathematical model is all limited, and first floor system obtains the output of a certain step as a result, being in fact
The result of several mathematical model COMPREHENSIVE CALCULATINGs.
2) reasonability of components " shape " and " position " exported can be corrected and be improved with the supervision to mathematical model.With
Sample known to system increases, and by learning process, the adaptability and reasonability of system output can be continuously improved.It can constantly solve
Certainly system is not suitable with problem, and knowledge accumulation is more easy.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the scope of the present invention.
