The Mould Design and Molding Crafts of Motorcycle tail lamp
[Abstract] This paper mainly talks about the situation and tendence of mould design in domestic and overseas countries,and points out CAD/CAE in the mold design application and the important meaning.The mould design of motorized rear tail lamp cover was introduced in this paper. First has carried on the detailed technological analysis to the chimney, from this determines the product material, mold's basic scheme, and has made the detailed introduction to the product material PMMA performance. Before entering the mold structural design, elaborated the injection molding basic principle, introduced the duplex profile injects mold's structure and the principle of work.According to the need of forming,the parameters of injecting machine was checked out detailedly. In carries on the mold structural design, the software carries on the fluid analysis through MoldFlow, causes the mold gating system which designs to be more reasonable is more reliable, meanwhile introduced with emphasis this motorized rear lamp tail cover injects the mold extruding system and lateral pulls out the core system. The incline guide pins were adopted,the drawing strength was computed clearly,and the intensity of the incline guide pins were checked out particularly.According the different materials of the mould,the intensity of the mould was computed clearly,in order to fullfil the request of safe and high efficient production. The mold structure uses the PRO/E4.0 software design, and produces the engineering plat,then using AutoCAD2004 to make the revision to consummate, causes the design the efficiency and the accurate enhancement,through the combination of experienced data and professional software,the design of the mould structure and its parts were completed efficiently.
