隔弧板注塑成型工艺及模具设计
摘要
本设计题目为隔弧板注塑模设计。通过对该零件模具的设计，进一步加强了设计者注塑模设计的基础知识，为设计更复杂的注塑模具做好了铺垫和吸取了更深刻的经验。
本设计运用塑料成型工艺及模具设计的基础知识，首先分析了塑件的成分及性能要求，为选取浇口的类型做好了准备；然后估算了塑件的体积，便于选取注塑机；最后分析了塑件的特征，确定模具的设计参数、设计要点及推出装置的选取。
系统介绍了塑件的成形工艺及模具成型结构对塑件质量的影响分析，浇注系统的设计，模具成型部分和总装结构的设计。介绍了隔弧板注塑模具设计时要注意的要点，并较多的考虑了模具结构的调整性、易更换性及模具成本。从控制制件尺寸精度出发，对隔弧板注塑模的各主要尺寸进行了理论计算，以确定各工作零件的尺寸，从模具设计到零部件的加工工艺以及装配工艺等进行详细的阐述，并应用CAD进行各重要零件的设计。

Abstract
This injection mould design of the plastic parts of flash barrier. The designer’s foundation knowledge of the injection mould design is reinforced and is able to design more complex injection mould through the design.Through the foundation knowledge, firstly, the composion and the perfourmance of the part is analyzed to choose the type of the gat advantagely. Secondly, the volume of the part is estimated to choose the injection molding machine. Lastly the character of the part is analyzed to determine the mould design parameter and design point and choose the ejection assembly.
The molding process of plastic parts, the effect analysis to plastic parts quality caused by molding structure, as well as the casting system design, partial and general design of mold moulding introduced respectively. The critical points of mold for plastic design are introduced, and the adjustable character of molding structure、exchange character as well as the molding costs are all considered farther. Starting from controlling dimensional accuracy, the carry the flash barrier to the main dimensions of injection molding are carried out so as to determine the size of different parts, the molding design and the process of parts as well as assembling process and etc of injection molding are stated in details.
