后盖旋钮注塑模设计
摘 要
根据塑料制品的要求，了解塑件的用途，分析塑件的工艺性、尺寸精度等技术要求，考量塑件制件尺寸。本模具采用一模两腔，侧浇口进料，注射机采用TOSHIBA EC40-Y型号，设置冷却系统，CAD绘制二维总装图和零件图，选择模具合理的加工方法。附上说明书，系统地运用简要的文字，简明的示意图和和计算等分析塑件，从而作出合理的模具设计。
关键词：机械设计；模具设计；CAD绘制二维图。
Abstract
To understand the use of plastic parts in accordance with the requirements of the plastic products, analysis of the technical requirements of the plastic parts of the process, dimensional accuracy, select the workpiece size of the plastic parts. The mold using a two sub gate feed injection machine adopts TOSHIBA the EC40-Y models, and set a cooling system, CAD drawing two-dimensional assembly diagram and parts diagram, reasonable mold processing methods. Attach a manual, use brief text, a concise diagram and calculated analysis of plastic parts, in order to make a reasonable mold design.
Keywords: mechanical design; mold design; CAD drawing two-dimensional map; injection machine selection.
