分线盒注塑模具设计及成型流动分析(说明书+CAD装配图+开题报告+任务书)
摘 要
分析了分线盒的结构特征,使用Pro/E软件进行分模设计,利用注塑模设计专家(EMX)外挂进行其模架的设计。为了减少试模次数,降低设计成本,选用Moldflow软件对塑件进行模具设计的优化分析,并对分线盒注塑模进行了流动模拟分析。
在进行塑件3D设计后,利用CAD进行2D的排位,制图和出图。主要注射模的定模机构、动模机构、浇注系统、导向装置、顶出机构、抽芯机构、冷却和加热装置、排气系统等的设计。
塑件流动模拟分析内容包括:充填分析、保压分析、残余应力分析。主要包括,充填时间、平均速度、气穴、熔接痕、体积收缩率、塑件变形等,由此获得满意合理的浇口数量和位置。
分析了降低塑件成本的方法,针对批量不大的不同规格结构形式的分线盒,设计成一模多用的模具。只需更换模具中的几个关键零件就可以生产多规格形式的塑件,减少模具数量,成本费大幅度减少。

ABSTRACT
Analyzes the structural characteristics of junction box,using Pro / E software for junction box design, use of injection mold design experts (EMX) plug-in for its mold design. To reduce the testing model, lower cost, and use Moldflow software for plastic mold design optimization analysis, and the junction box for simulation.
After plastic 3D design course,using CAD software for qualifying, drawing. Fixed the mold main body, the dynamic model agencies, casting systems, guiding device, top the body, core-pulling mechanism, cooling and heating equipment, exhaust system design.
Plastic flow simulation analysis include: filling analysis, packing analysis, residual stress analysis. Include, filling time, average speed, air traps, weld lines, volume shrinkage, plastic deformation, thus reasonably satisfactory number and location of the gate.
A multi-purpose injection mould for an adapter junction box was developed.With replacement of some key components in the mould,various specifications and structures of adapter junction box can be made and therefore the manufacturing costs are reduced.
Keywords: adapter junction box; CAD/CAE; Moldflow; multi-purpose mould; sliding core
