According to above take shape the method characteristics, take shape the technical function quickly to consist in primarily:The manufacturing useds for the design with the on trial product model, make to used for the small the molding tool that batch quantity produce to process with the special spare parts in small batch quantity.Take shape the product model of the technique manufacturing quickly in the aspects of material the ratio tradition processes the product model of the method manufacturing has the difference,But in shape and sizes almost complete similar, and there is certain machine strength, can make the function experiment, handles through surface at the same time, looking similar to true product,Can advertise the propaganda material.Take shape the molding tool of the technique manufacturing quickly.
Is a soft material to take shape the mold( the mold of design , wreath oxygen resin mold, design rubber mold, low design orders the metal alloy casts mold etc.) primarily to synthesize the hard type in material Ç» mold with porcelain and ceramics or metals »ùs now.Hard mold in manufacturing the hour can take shape with the fleetness the spare parts makes the female die.
Create first the soft mold between wreath oxygen resin mold or other material, sprinkle to note porcelain and ceramics or gypsum molds in soft mold, then sprinkle the steel of design steel mold; or sprinkle the admixture that note in soft mold chemistry contain steel powder glue knot.
Proceed to burn to become the steel mold.Take 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 design .Because the molding tool sprinkles to note or burn the knot with the steel powder .
Material and common 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 produce.Moreover, 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, design mold legal system makes graphite electrode etc..
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 design with each link information that realizes the technique gathers.
The information gathers unify with data the management is a key.The information of the product is to pierces through in the design, analyze, process, examine, assemble a stage.
Fluency, solution data format that realizes each link information standardizes and the data maintenance is a point with future CAD that share to gather technique development.The system of PDM emergence is to resolve this problem brought the first light of day.It is molding tool business enterprise application CAD that the system of PDM puts into practice gather technical and important lesson.Design in molding tool manufacturing aspect,The intelligence that imply the research, high speed that abundant expert''s knowledge turn molding tool CAD/ the system of CAM slices the design processes and its plait distance etc. is a trend that future study the development.
