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 divide the type, certain type C? according to the product model molding tool of proceeding the design with the type D? , molding tool structural and detailed design, the plastics 3a 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 dividing the type,
Born top and bottom mold C? with mold D? , 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 use 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,
Can the development imitate the true analysis plastics to inject in note EU mold C? the process flows the circumstance( the plastics with sprinkle a people more inject remits to flow the analysis of ?AE ), analyze the temperature pressure variety circumstance and analyze to note EU a 2D 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 C? ; whether to exsit product construction absurdity or molding tool constructions or not is not reasonable, appearing the product A 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 EU wrong, appear the song of CI 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 a, 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 manufacturingwww.mapeng.net
ml;I processing, line incising to process, electricity spark processing to wait.The technique of CAM rises in the type C? , type D? of the complicated molding tool and the I I of the electrodes process particularly more important function.Its main technique characteristics includes:
(1) the O , ?? 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 ,(3) slicing the ?÷ process the craft parameter to really settle,(4)
The commonness slices the ?÷ to slice with the high speed the characteristic that I process controls,(5) over slice the check with process the superficial accuracy control,(6) processing the computer entity of the process imitate the realistic I ,(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 I 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)
Because making use of the parameter turns the characteristic shape design with same database technique, making the type C of the product model data, molding tool have the track data to have got the inside contact with the type D? model data, knife,
The modification knife of the product model has the track to also modify automatically.
The molding tool processes the entity imitates the true technique more and more mature, also is more and more valued by people.It is mimicry machine bed that processing the entity imitate process the process on the computer, can keep the result that view reflect process,
Can takes the gauge of directly quantity that after processing spare parts, can check the mistake that process.At check quantity that after processing spare parts, can at the computer is last to process behind of the entity model proceeds the aleatoric EE slices,
Measure its size directly with the accuracy.Therefore, it can dissolve mistake at process the stage of craft plait distance design, reduce to repair after processing with return the work, increases consumedly the manufacturing efficiency of the molding tool with quantity.
5, plastics product and its molding tools take shape the manufacturing quickly Plastics product and its molding tools use the computer CAD techniquewdesign after completing, can pass the fleetness take shape the technique make.This is the
南华大学船山学院毕业设计（论文）
manufacturing technique of a kind of all new concept,
It abandoned the traditional machine processes the method.Its take shape principle is three I CAD entity models are long.lost set up a series of a layer data of the thickness, make use of the laser take shape machine or others take shape the equipments read these datas,
Increase the method technique with the material, pile up the each layer to take shape one by one in order.This technique calls the fleetness to take shape the technique automatically.( Rapid Prototype)It is also a CAD to gather the technical importance constitutes the part.
The first pedestal takes shape the equipments quickly to bear in the United States a company in 1987, because of its characteristics is to has nothing to do with the complicated degree of the product of the manufacturing, bringing the manufacturing industry the enormous vibration.Henceforth decade,
Take shape quickly the technique be flown to develop soon, the category of the equipments also piles up one after another,
Turn from the material I the method can is divided into the laser with not the laser burns the knot method( SLS), solid surface layer shape method( SGC), layer a manufacturing method( LOM) and melt to sink to accumulate the method( FDM), district constituency glues the knot method( DSPC), laser spirit to sink to accumulate method( SALD) etc. mutually.Every kind of method characteristics is:
The method of SLA is applied at the earliest stage of took shape the technique quickly, the early market occupied the bigger cent sum, but is narrow because of the material scope, the cost is higher, taking shape the piece was heat.proof and bore the burthen with applied color the ability low,
The recent years was gradually replaced by the other method.The method of FDM because of taking shape the speed quick, the cost is low, get the good application in plastics product profession, because the size of the spare parts is small, accuracy bad,
Also suffer certainly of restrict.The method of LOM because of adoption paper or is outline edge that thin slice plastics, the cost is low, and the laser projects light upon each
