Title Earplugs shell injection mould CAD dedign
Abstract
"Earplugs shell" as the theme in this design.On the basis of the traditional mould designed by CAD technology to conducted a comprehensive mold design.Earplugs shell with uniform thin wall, in the design of the surface is smooth, small size and complexed shape.So choose one module and two cavities of vertical double parting surface injection mould structured.Choose the priority design of mould cavity structure, and then in turn was the core structure, inclined guide pillar and slided block, guides and reset pole, push rod and launch mechanism, the aim was to standardization.In the process of design, but also through injection molded CAE technology, the sprue, injection molded process in the dynamic analysis and simulation, so that in the design phase of the design scheme comparison, to find problems in time, avoided the after completion of the mould processing to the tested stage to found the problem.At the same time, in the design to measure the relationship between product quality and cost, and try to make the mold of the simple structure, low cost, easy processing, good usability.
