Can the development imitate the true analysis plastics to inject in note mold the process flows the circumstance( the plastics with sprinkle a people more inject remits to flow the analysis of ), analyze the temperature pressure variety circumstance and analyze to note a remaining should dint etc.,According to analyze the circumstance to the rationality that check the molding tool construction, flow quantity problem etc. of the rationality, product of the appearance.For example whether the esse sprinkles to note the system not reasonable, appear to flow way with sprinkle a position size not appropriate.
Can''t equilibrium alive with type; whether to exsit product construction absurdity or molding tool constructions or not is not reasonable, appearing the product design dissatisfied( namely short shoot the phenomenon); whether to cool off asymmetry or not, the influence produces the efficiency with product quantity;Whether the esse notes the craft of wrong, appear the song of design 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 rate.
At plastics molding tool design with analyze to apply many new computer-aideds technique this stage, if the parameter turns technique, characteristic 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 design , 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, efficiently.The parameter turns the characteristic shape can not only describe the product completely 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 characteristic.Therefore,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 manufacturing
The calculator assistance manufacturing( CAM) technique of the molding tool applies primarily in the aspects of counting to control processing, line incising to process, electricity spark processing to wait.The technique of CAM rises in the type design , type design of the complicated molding tool and the design of the electrodes process particularly more important function.Its main technique characteristics includes:
(1) the design processes the knife have the track excellent to turn the programming with the instruction of NC creation,(2) the knife has the category, characteristic to establish with the material design ,(3) slicing the design process the craft parameter to really settle,(4)The commonness slices the design to slice with the high speed the characteristic that design process controls,(5) over slice the check with process the superficial accuracy control,(6) processing the computer entity of the process imitate the realistic design ,(7) The computer control number controls the technique of DNC and clusters of the machine bed control the technical and applied etc..
Need the CAD specially in technical application in CAM three design product model data.More profession computer plait distance software,such as MASTERCAM, UNIMOD, etc. of CIMATRON, when the plait distance of many curved faces processes have the higher request to the curved face model of the product,Intend with the high accuracy of the curved face to match such as the directional consistency, curved face in U, V of the close together curved face, inclined rate in curved face continuous variety etc..In high class CAD/ the integral whole of CAM turn system,( such as UGII, PRO/ E).
