笔盒注塑模具设计

AbstractThe graduation design topic comes from our common stationery pen boxes,pen boxinjection mold design process in detail in this paper.Design process including plasticmaterial characteristic,choice of injection molding machine,the parting surface ofproduct model,the analysis of the plastic parts structure and injection molding systemdesign including the gating system and selection,the parting surface selection of plasticinjection molding parts,mold,injection mold,east side core-pulling mechanism design,injection mold ejector demoulding mechanism design,injection mold temperaturecontrol system,etc.Integrated box,plastic pieces of the structure characteristics of themould design adopted the form of the side gate,thimble stripper.Step in coarse afterdesign the injection mold and to the injection pressure,injection machine biggestmould stroke as well as the content,check is the guarantee for the purpose of theinjection machine and mold to cooperate with each other,and mass production.In thedesign process,use a lot of university to learn the professional knowledge,from theoryto design,with the theory of design,inspection,so as to better apply theory,deepenedmy understanding of the principle of the injection mold design,using the theory ofdesign,in addition to traditional calculation method,many times I still use AuToCAD,UGsoftware,simplify the design process,improve the design precision and efficiency.Keywords:Plastic box;Gate;Injection molding machine;Mold release2-
