DVD装饰板注塑模设计 摘要 塑料工业在社会中起到越来越重要的作用，影响着我们的衣食住行。此次模具设计的题目是《DVD装饰板注塑模具设计》。这个塑件是个薄壁体，尺寸相对比较小，通过对塑件的工艺性分析，选出合理的注塑机注塑。本人认真仔细的分析图纸，对分型面，浇注系统成型零件的结构，脱模推出机构，模架，冷却系统进行了详细的设计，并附上图。该模具采用一模四腔的布局，其中浇口设计与成型零件的设计进行着重说明，通过这次的设计，对模具的发展，作用有了更深的认识，把理论知识能运用到这次设计中去，并能熟练地用绘图软件将其画出来，此DVD装饰板采用侧浇口的方式进行浇注。塑件采用ABS材料，该材料密度为1.02g/—1.16g/，平均收缩率为0.55%，该模具结构简单，使用寿命长，可进行大批量生产。 关键字：DVD装饰板，ABS,成型零件，浇注系统，浇口 DVD decorative plate injection mold design ABSTRACT The plastics industry plays an increasingly important role in society, affect our basic necessities of life. The problem of the mold design is the DVD decorative plate injection mold design.. This plastic part is a thin wall, the size is relatively small, through the plastic parts of the process analysis, choose a reasonable injection molding machine injection molding machine. I carefully analysis of the drawings, binary type, structure of gating system, forming parts, demoulding launch, mold, cooling system were detailed design, and the enclosed figure. The mold with a mold four cavity layout, the gate design and forming part of the design are emphatically described, through the design, to mold the development, the role of the deeper understanding, the theory can be applied to the design to, and can skillfully use drawing software to draw it out. This DVD decorative board the side gate for casting. Plastic parts using ABS material, the material density of 1.16g/ - 1.02g/, the average shrinkage of 0.55%, the mold structure is simple, long life, can be mass production. Keywords: DVD decorative plate, ABS, molding parts, gating system, gate 目录TOC \o 1-3 \h \u 27875 摘要 1 16630 1 .绪论 1 15608 1.塑料工业的发展 1 11181 2. 模具的材料类型 2 5388 2 、塑件成型工艺分析 4 24426 2.1 成型材料性能分析 5 14356 2.2 塑件结构工艺性分析 6 25910 2.3分型面位置的确定 6 23837 1）分型面确定 7 18804 2.4注射机型号的选择确定 7 21112 1）注射量的计算 8 11969 2）锁模力的计算 8 20381 3) 选择注射机 8 14548 4)注射机参数的校核 9 4858 3.浇注系统的设计 11 6041 3.1浇注系统的基本要点 11 4920 3.2主流道设计 12 31699 1)主流道尺寸 12 1993 2)主浇道衬套设计 12 189
