基于UG的汽车安全气囊盖注塑模具设计

AbstractThe design of the subject is car airbag cover,is a common plastic in daily life,throughthe analysis of plastic use and assembly requirements that use production batch is large,needto ensure that the mold can high life effectively fast mass production,combined with the sizeprecision,shape structure,appearance requirements,the use scenario requirements analysiscan know this is a appearance of plastic parts,in the mold design of mold process analysis toensure that when injection molding can obtain high quality of plastic productsThis design adopts the type cavity arrangement of one mode 2 cavity,And design andcalculate the size and determination of the forming parts,The pouring system is designed asthe pouring mode of the latent horn pouring gate,The pouring system includes the mainstreamroad,diversion channel,pouring gate,cold material hole and other institutions,Theintroduction of the plastic parts for the classic conventional push rod 5 diameter 8mm roundpush rod to release the molding mode and the molding mechanism of the analysis and design,The widely used surround cooling pipe diameter of 8mm is used for cooling,The new nationalstandard GBT/12555-20006 formwork selection,The mold manufacturer is the standardmold frame CI3050-A60 B90 C90 produced by Longji Company (LKM).Key words:automobile airbag cover;molding process;mold release mechanism;molddesi
