| Abstract: | The injection technological characteristics of lunch-box cover are analyzed,and the design main points and working process are also introduced. The design method of plastic structure is mainly introduced. The selection of the sidewall thickness,the decision of the mould cavity number,the selection of injection machine,and the designing process of the parting plane,the exhaust system,cool material cave and pin gate are stated. The design structure characteristics of lunch-box cover are three times parting plane with pin gate style,and side core-drawing structure. |
