风扇底座注塑模具设计

摘要

根据塑料风扇底座制品的要求，了解塑件的用途，分析塑件的工艺性、尺寸

精度等技术要求，选择塑件制件尺寸。本模具采用一模一腔，环形浇口进料，注

射机采用海天360X2B型号，设置冷却系统，CAD和proe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，从而作出合理的注塑模具设计。

关键词：风扇底座；浇口进料；注射机；冷却系统，注塑模具

Abstract

According to the requirements of plastic fan base products, understand

the use of plastic parts, analyze the technical requirements of plastic parts

such as workmanship, dimensional accuracy, and select the size of plastic

parts. This mold adopts one mold, one ring and ring gate feed. The
