三星手机后盖注射模具设计
[摘要] 注射成型是热塑性塑料成型的主要方法之一,可以一次成型形状复杂的塑件。本次课程设计对三星手机后盖注射模具进行了设计,对塑件结构进行了工艺分析,确定ABS为塑件的材料。采用一模两腔的结构,并根据模具的锁模力选择了注射机,再用注射量、注射压力进行了校核。对浇注系统进行了设计,采用端面进胶的侧浇口,并对流道进行了布置,根据注塑机的型号确定了定位圈与浇口套的尺寸与形式。选择了Futaba公司的标准模架,对顶出装置与冷却系统进行了设计。对成型零件进行了设计,确定了模仁的大小并在Pro/ENGINEER进行开模。进行侧抽结构的设计,确定导柱的倾斜角、长度,并对滑块的结构进行设计。最后在EMX下生成三维图,导入AutoCAD对装配图和零件图进行绘制。

Design of The Plastic Mold of The Back Cover For Samsung Mobile
Abstract Injection molding is one of the most significant measures in thermoplastics forming, which can plex parts directly. During this Mold Course Design, a design of the plastic mold of the back cover for Samsung mobile has been carried out. The structure of the product has been analyzed according to the manufacturing process and ABS was choose as the material of the back cover. There would be two cavities in a mold for increase efficiency. Based on clamping force, the model of injection molding machine has been choose, and the calculation of injection volume and injection pressure has been done to make sure the machine could work properly. Using side gate as the way of filling cavity and placing runner in proper way, the design of gating system has pleted. The model of injection molding machine determined the type of locating ring and sprue bush. The mold base of pany has been choose and the design of eject system and cooling system have been done. To create molding parts, the size of mold core has been decide and the appearance of cavity and core has been generated by Pro/ENGINEER. After deciding the slant angle and length of angle pin, figure out the structure of slider, the design of side core pulling system has pleted. Finally, three-dimensional diagram has been generated by EMX, and then it has been imported to AutoCAD to create assembly drawings and part drawings.
