耳机塑料模具设计(CAD,Proe三维)

耳机塑料模具设计(CAD,Proe三维)(任务书,开题报告,中期检查表,外文翻译,设计说明书19000字,cad图纸5张,Proe三维建模)
摘要
近年来，工程塑料以其优异的性能获得了越来越广泛的应用。而注塑模具是
其中发展较快的种类，在人们生活的各个领域都能够见到塑料制品。因此，研究
注塑模具对了解塑料产品的生产过程和提高产品质量有很大意义。
本设计分析了耳机的结构，提出了模具设计的关键点，设计了模具的整体结
构。根据塑件分型面的位置，设计了斜导柱外侧抽芯结构，零件采用了单分型面
的点浇口，提高了零件的外面质量。通过对塑件进行工艺的分析及其结构分析，
从产品结构工艺性，具体模具结构出发，对模具的浇注系统、模具成型部分的结
构、顶出系统、注射机的选择及有关参数的校核都有详细的设计。该模具一模四
腔，采用顶针顶出结构。经过生产验证，该模具结构合理，动作可靠。

The Plastic Mold Design of headphone
Abstract
Inrecent years,more  widely plastics for  its excellent  performance. The injection
mold is  a fast-growing type  of plastic products  in all areas  of life people  are able  to
see. Therefore, the study of injection mold has a great understanding of the production
process of plastic products and improve product quality.
The design  and analysis of  the structure of the  headphones, the critical  point of
the  mold design,  the overall  structure  of the  design  of the  mold.  According to  the
position  of  the   parting  surface  of  plastic   parts,  design  Bevel  Pillar   the  outside
pumping  core structure,  the parts  are  made of  a  single sub-surface  point  gate, and

improve the  quality of the  parts outside.  Process from the  product structure, process
analysis and  structural analysis of  plastic parts, the  specific mold structure  departure
check  of  the  selection  and  the  parameters  of  the  casting  mold system,  the  mold
forming part of the structure, ejection system, injection machine has a detailed design.
The mold cavity of a mold, ejector structure. The  mold production-proven, reasonable
structure, reliable action.
