Take shape the technique creation molding tool quickly to model the equipments with the product, all is STL to read CAD system creation or CLI etc. document format datas， Different document format data to the product accuracy of the creation contain bigger margin, therefore, study the system of CAD to take shape quickly the document format of the equipments output to have the very important meaning. 6, the molding tool CAD gathers technical development trend A calculator for saying, molding tool CAD gathering technique is applying in molding tool making each link assistance technique on the 219。 .Because the molding tool sprinkles to note or burn the knot with the steel powder but,Material and mon molding tool steel contain certain margin, therefore, the life span is shorter, cans make to manufacture on a trial basis product or small batch quantities , taking shape the technique quickly can also manufacture the special spare parts,If make with the metallurgy powder legal system the metals electrode, nicety cast the legal system makes the copper electrode, 209。 or sprinkle the admixture that note in soft mold chemistry contain steel powder glue knot,Proceed to burn to bee the steel shape the steel mold of the technique manufacturing quickly to process after needing further did to throw light etc., make into the small batch quantity produce of note the mold of 203。253。249。187。219。232。175。175。204。172。 202。190。187。172。247。247。247。247。226。171。214。247。179。190。187。247。179。 , like this since can realize the data share,Can satisfy the customer again to the at any time modifying of the design, make the design analysis of the molding tool fast, accurate, parameter turns the characteristic shape can not only describe the product pletely then several why sketch information,And can acquire accuracy, material and assemble etc. informations of the product, its a product for establishing model is a kind of apting to handle and can reflect design intention with process the model of the ,The parameter turns the characteristic shape technique is an one of the most important technique in process in manufacturing in molding tools. 4, the technical application in CAM of the molding tool process to imitate true and manufacturingThe calculator assistance manufacturing( CAM) technique of the molding tool applies primarily in the aspects of counting to control amp。 of the product transform etc..The molding tool passes the CAD the design with analyze, can dissolve mistake at design the stage, increase to try once the mold the success the plastics molding tool design with analyze to apply many new puteraideds technique this stage, if the parameter turns technique, haracteristic shape technique, database technique etc..There is many standards piece in the plastics molding tool,Turn such as the standard mold a parameter for outing organization, sprinkling noting system, cooling system...etc. can adopting basing on database managing the characteristic shape design method proceed the design or establish the standard a 191。 wrong, appear the song of 199。Whether the esse notes the craft of 203。 dissatisfied( namely short shoot the phenomenon)。 whether to exsit product construction absurdity or molding tool constructions or not is not reasonable, appearing the product 179。187。39。208。220。198。187。220。190。187。228。190。187。220。171。199。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。 shape designs is a true shape that the product that the arithmetic figure turn design, it expressed pletely product,Can be further to designs for the molding tool, analysis with processes the mathematics model of the necessity of offering。 three 206。172。s 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。 free shape in product and advertise the software of the design have:Alias, etc. of 206。172。s have:ME10, CADKEY, AUTOCAD, DHCAD, Genis, etc. of Sigraph。 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 the software of 206。s turn the entity shape the design, three 206。 characteristic shape design, three the parameter of 206。 entity shape design, three 206。s turn the design of the sketch, three 206。s are several why the sketch draws, two the parameter of 206。 models proceed to process to weave the distance and establishment crafts kind of method makes product model design, molding tool construction design, process to weave distance and technological designs regard a data as the foundation, realizing the data share,Can not only increases to design the efficiency quickly, but also can guarantee the quantity, decline low cost. a product model has three kinds of:Making use of the CAD system software proceeds the product model the design and make use of the real object measures fast anti in proceeding beg to set up the mold and make use
