【摘要】 传统的模具设计与制造方法已经不能适应工业产品不断开发、及时更新换代与提高质量的要求,为了适应这些变化,使用CAD/CAE/CAM技术可大大提高注塑模具设计的速度和质量。利用传统的设计方法计算塑料名片格的注塑模具主要参数,并对注塑模具的细节部分进行设计。利用UG/MoldWizard软件对整个模具进行三维实体造型,包括型芯、型腔、模架、镶件、滑块、浇注系统和冷却系统等部分的三维设计。并采用决定产品几何造型及成形条件最佳化的进阶模流分析软件Moldflow/MPI进行了有限元仿真分析,选择两种冷却管道设计方案,分别从冷却时间和零件翘曲等两方面进行了分析,最终选择第一种冷却管道布置方式。更多还原

【Abstract】 Traditional mould design and manufacturing methods can not meet requirements of the constant development, timely updating on industrial products and improving the quality, in order to adapt to these changes, the use of CAD/CAE/CAM technology has greatly improved the speed and quality of design molded plastic components. The main parameters are calculated by the traditional way. UG/MoldWizard is adapted to create the 3D mold model, including core, cavity, state aircraft, insert pieces, slider, filling systems and cooling systems architecture design. Moldflow/MPI that is the better product geometric shapes and the shape conditions of the advanced modules flow is used to FEM analysis. Two kinds of projects about the cooling pipeline are chosen. They are analyzed that cooling time and part warp. No.1 project is selected.更多还原
