【正文】 dition analysis, the plastic melt filling analysis, cooling quality analysis, shrink mark analysis, injection pressure analysis. III This design is a mold two cavity three plate mold. Due to the special shape of gargle cup, not directly release, need to set up the side parting mechanism, the mold is through the inclined guide pillar side parting, the mold of each part of the design and calculation. At the same time on cavity important parts to processing technology development and the core of NC machining simulation. This paper gives the detailed design process and assembly drawings. Keywords: tooth glass the note molding side parting Simulation modeling NC machining 目錄 第一章 概述
