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.
