Article key introduces the method building a warehouse of library of standard spare parts, package library, be based on UG/Part Families to build parameter to change mould standard component library, package library and mould bases library, among them the drive of package comes true through building index file. The standard component library of article introduction basically includes library of standard spare parts and package library, it is the necessary measure that raises a mould to design efficiency. Although current CAD system can realize the design that parameter changes, satisfy different assembly thereby demand, but design efficiency to rise further, mould standard spare parts and component also must realize parameter to change. Additionally mould standard spare parts and component also should be contained assemble information, ability realizes automation and intelligence to change. In die standard component in the library, a standard component basically has 2 files, namely model file (Prt) with data file (Dbf) . The content of standard component library uses 2 level structure commonly, the first class is a database advocate guide a file. The 2nd class is the DBF data file of the spare parts, this DBF file recorded standard component a series of parameter. To standard component, need uses document of 3 class data. Library procedure is established in standard component in, the user must build model of standard component information first, the content cent of the input is 3 kinds, it is three-dimensional parameter turns diagnostic substance model; 2 it is diagnostic variable; 3 it is to assemble information. They put store with particular structure in the database, provide the complete description of pair of standard spare partses or component. One parameter converts warehouse of standard spare parts in building the construction in library of standard spare parts, main application is based on the parameter of diagnostic variable to devise a method. In the procedure that establishs in the model, add design variable, express medium expression through designing variable, set the associated regulation between variable, important parameter uses Excel form to control, through coming to designing the modification of variable drive makes new part. Concrete move is as follows: In three-dimensional CAD environment, build product substance model; Come to the data related every feature express with variable, manage in order to facilitate variable drive is mixed; To the diagnostic dimension of mutual correlation, in the expression in the formula of variable watch, simplify hypostatic dimension element. If the graph is shown 1 times,the standard component in UG system builds flow. Graph 1 standard spare parts builds flow to be with commonly used guide pillar below exemple, use UG/Part Families to build warehouse of spare parts of standard of guide pillar series. Expression of maths of die standard guide pillar is built in Expression watch, by model of mathematical expression drive. If pursue,build input maths expression 2, diagnostic variable included to define in the graph. Graph after 2 maths expression inputs mathematical expression, build parameter to turn diagnostic model according to expression, if pursue 3. Graph after parameter of 3 features model changes diagnostic model to build, have diagnostic variable list, the dimension definition that changes need is parameter symbol, if express,make diagnostic variable list 1. A parameter was listed only in the watch, and code name and description for empty. The dimension that expresses list of 1 feature variable to be tagged with the symbol in diagnostic variable list is member of a group of things with common features watch, the feature of the dimension that did not add is those who be not change, feature of other of leech on to and exist, important measure can use expression to undertake associated design in Expression watch. A group of things with common features watch is essentially develop a list by what travel and row form, the author basically uses Excel to found. After diagnostic variable list is generated, can go to relevant model variable is added in the watch. In applying actually, the guide pillar in usable graph is kind belong to model a future life to become a series of standard component, through editing Excel form, the die standard guide pillar that sells on the market at present, by GB (GB) the model variable of the guide pillar that with each standard component the industry standard of the factory undertakes manufacturing inputs a watch in, if express 2. It is OK in Excel to express 2 models variable the measure value of the example that edits a need, the Excel of here and commonly used Excel are much merer a Partfamily, numeric input ends, must use Partfamily → Samefamily save file to disk. In the watch, luggage contained example and they proper cost, the row is used by specific project. Another advantage of a group of things with common features watch is no matter you found a new table to still revise already some watches, you can add an item to the middle of the watch. Use afore-mentioned method, the three-dimensional mould standard component that each enterprises can need to build his according to mould design library. Build the next pattern plate, guide pillar, upper mould board, bolt, dust cover, spare parts warehouse such as guide-post bushing with same method, here author does not make the introduction.
