3塑件三维外侧
摘要
此以蓝牙耳机外壳为设计模型，以塑胶模具设计与制造，模具加工工艺的相关知识作为依据，讲述整个蓝牙耳机外壳注塑模具设计过程。设计初期首先使用UG软件进行蓝牙耳机外壳的实体造型。然后分析得到最佳注射点和注射方式。最后明确设计思路，确定成型工艺。模具结构可采用一模两腔，侧浇口进料，注射机采用海天80×A型号，并对其相关的数据进行校核。首先根据UG软件设计出分型面，进而设计出型腔、型芯。通过各种手册选择标准模架的绘制，并且进行分型面的选择、浇注系统、脱模机构、冷却系统、标准模架的选用等模具重要结构的设计。塑件内部倒扣可采用斜顶抽芯机构，利用推出机构的推力驱动斜导柱斜向运动，在制品被推出脱模的同时由斜导柱完成侧向抽芯动作。
此结构可确保模具工作运行平稳并保证配件之间的配合精度，通过对蓝牙耳机外壳注塑模具的设计，帮助我总结并深化了所学的模具设计，模具加工工艺的相关知识，达到了我的设计意图。

Abstract
This paper takes the Bluetooth headset shell as the design model, based on the knowledge of plastic mold design and manufacturing, and mold processing technology, describes thewhole injection mold design process of Bluetooth headset shell. At the beginning of the design, UG softwarewas used to model the Bluetooth headset shell. Then the best injection point and injection modewere obtained. Finally, the design idea and the forming process are defined. The mold structure can be usedwith one mold and two cavities, and the side gate feed. The injection machine adopts Haitian 80x A model, and check the relevant data. Firstly, the parting surface is designed according to UG software, and then the cavity and core are designed. The drawing of standard die base is selected throughvarious manuals, and the design of important die structures such as selection of parting surface, gating system, demoulding mechanism, cooling system and selection of standard die base are carried out. The core pulling mechanismwith inclined top can be used for internal buckling of plastic parts. The oblique motion of the oblique guide pillar can be driven by the thrust of the pushing mechanism. The lateral core pulling action can be completed by the oblique guide pillarwhen the product is pushed out of the mould.
This structure can ensure the smooth operation of the die and ensure the accuracy of the parts. Through the design of injection mould for Bluetooth headset shell, it helps me summarize and deepen the knowledge of the die design and processing technology, and achieves my design intention.
Keywords: Bluetooth headphone shell; injection mold; one mold two cavity; side gate; injection machine; cavity; core.
