Making use of the CAD system software proceeds the product model design.Its technique includes primarily two are several why the sketch draws, two the parameter of turn the design of the sketch, three entity shape design, three characteristic shape design, three the parameter of turn the entity shape the design, three curved face shape design, free shape in space design, the external appearance of the product exaggerates, product of dynamic advertise to design the etc..These softwareses contain many typical representatives.Two the software of design have:ME10, CADKEY, AUTOCAD, DHCAD, Genis, etc. of Sigraph; three the software of design have:UGII, PRO/ E, IDEAS, CATIA, etc. of EUCLID; free shape in product and advertise the software of the design have:Alias, etc. of CDRS.Two design are several why the sketch draws is to make use of the flat surface CAD software draw the spare parts sketch, then replace the handicraft painting with the calculator; but two the parameter of design turn.
Then the calculator realizes the sketch changes the deal designs, making modification more convenient; three design shape designs is a true shape that the product that the arithmetic figure turn design, it expressed completely product.Can be further to designs for the molding tool, analysis with processes the mathematics model of the necessity of offering; the free shape in space design is the art of the product shape to design, making product been not only is a function product, but also art article.
It is every kind of need that the external appearance of the product exaggerate that product of the result designs, making product more beautiful, the color can attract people more; the dynamic advertisement design of the product is a result that design to make to promote the advertisement directly the product,Proceed the market expansion.
Making use of the real object measures fast anti of proceeding beg to set up mold is current investigative a little bit hot of a,It is an important technique that product imitate the type foundation go forward a line of the product modification designs.Its basic principle is to passes three coordinateses measure the machine, laser measure machine or electronicses copy the few to proceed to scan the diagraph to the real object,The data of large quantity that arithmetic figure turn that gets to measures the acquisition orders anti that send into the high class CAD software beg mold piece or appropriative anti beg the software inside, anti beg the software can read directly a data cluster,Combining can proceed the editor, filter, tidy up, beg the to a data cluster, row preface, part modification and reorganization, then automatic born curved face,It is end to acquire together the real object precision is consistent of or computer a product model that pass through reforms.This way can increases biggest new product design velocity.Current mature curved face anti beg to set up the mold software has: Surfacer.Cimatronrenge, etc. of Strim100.
Make use of the standard format document of the other the system of CAD to set up the mold, this way than convenience.Because the world of the market turns with the technical development in the network of INTERNET.The CAD technique exchanges of the molding tool business enterprise with cooperate to have many pass the CAD document method proceed.Because the CAD system category is more, therefore documentary format must follow the international standard.Such as the DXF, IGES, STEP, VDA, etc. of STL.Pass to read standard format document to stablish directly or establish the product model after modifying, since can quickly, deepen the customer and the exchanges of the molding tool factory house.Also can shorten the product the design the period.
3. the CAD design of the molding tool and analysis
The CAD design of the molding tool, analysis.Include to pide the type, certain type according to the product model molding tool of proceeding the design with the type, molding tool structural and detailed design, the plastics ³ä fills process analysis etc. a few aspects.Make use of the advanced characteristic shape software,such as PRO/ E, etc. of UGII, the very easily certain piding the type,Born top and bottom mold with mold , then the proceeding flows a way, sprinkle a people and cool off the pipe line of arrange etc..Made sure these designses data hereafter, then make us e of the molding tool analysis software,Proceed such as the MOLDFLOW, CFLOW the plastics take shape the process analysis.According to the software of MOLDFOLW with it of the material, craft database of plentifulness, pass the importation take shape the craft parameter. 塑料模具CAD集成技术英文文献和中文翻译(2):http://www.youerw.com/fanyi/lunwen_5731.html
