2.MoldTypes

2.1InjectionMold

Aninjectionmoldisatoolusedintheplasticinjectionmoldingprocess.Itconsistsoftwomnparts:thecavitysideandthecoreside.Thecavitysideformstheexternalshapeoftheplasticpart,whilethecoresideformstheinternalfeaturesofthepart.Keytermsrelatedtoinjectionmoldsinclude:

Runner:Thechannelthroughwhichmoltenplasticisinjectedintothemoldcavity.

Gate:Theopeningthroughwhichmoltenplasticentersthemoldcavityfromtherunner.

Ejectorpin:Apinusedtoejectthemoldedpartfromthemold.

2.2DieCastingMold

Diecastingisametalcastingprocessthatisusedtoproducecomplex-shapedmetalparts.Thediecastingmold,alsoknownasadie,ismadeoftwoparts:thecoverdieandtheejectordie.Someimportanttermsrelatedtodiecastingmoldsare:

Cavity:Thepartofthediethatformstheexternalshapeofthecastpart.

Core:Thepartofthediethatformstheinternalfeaturesofthecastpart.

Sprue:Thechannelthroughwhichmoltenmetalispouredintothedie.

Runnersystem:Thechannelsandgatesthatdistributemoltenmetaltotheindividualcavities.

3.MoldDesign

Effectivemolddesigniscrucialinensuringtheproductionofhigh-qualityparts.Molddesignersusespecializedsoftwaretocreate3Dmodelsofmolds,consideringfactorssuchasmaterialflow,cooling,andpartrelease.Herearesometermsrelatedtomolddesign:

Draftangle:Thetaperorangleaddedtotheverticalsurfacesofthemoldtofacilitatetheremovalofthepart.

Partingline:Thedividinglinebetweenthecavityandthecoreinamold.

Shut-offsurface:Thesurfacethatpreventsmoltenmaterialfromleakingoutofthemold.

Coolingsystem:Thesystemofchannelsandcoolingelementsinthemoldusedtocontrolthetemperatureofthemoldandthepartduringproduction.

4.MoldMakingProcess
