摘 要本论文的题目为音响外壳注塑模设计，按照给定的塑料零件的结构特色、精度水平和材料对塑料零件进行分析，了解音响外壳的基本用途，进行工艺性分析，音响外壳的材质为 PC，音响外壳的外形以中心面对称，两侧均有筋板，根据塑件的尺寸大小选择了一模二腔的排列方式，侧浇口进行浇注，对浇注量进行计算，注塑模型使用海天 HTF80XB 设计的冷却系统，和脱模手段进行了比较和选取，对模具结构进行检查，并对完整的模型进行模流分析，采用 NX UG6.0 软件用于完成模具的整体设计和完成零件图的绘制，并完成设计规范的编写。关键词：机械设计；模型设计；CAD 绘制二维图；注射机ABStractThe topic of this thesis is the design of injection molding mold for acoustic shell. According to the structural characteristics, accuracy level and materials of a given plastic part, the plastic part is analyzed, the basic purpose of the acoustic shell is understood, and the process analysis is carried out. The material of the acoustic shell is PC. The shape of the acoustic shell is symmetrical in the center, with ribs on both sides. According to the size of the plastic part, a mode of arrangement with two cavities is selected. The side gate is poured, the pouring amount is calculated, and the injection model is used. The cooling system designed by Haitian HTF 80XB, Compared and selected with the demoulding method, the die structure was checked, and the complete model was modeled. The NXUG6 .0 software was used to complete the overall design of the mold and complete the drawing of the part diagram, and the design specification was completed.Key words: mechanical design; die design; CAD drawing two-dimensional map; injection machine目 录摘 要..........................................................................................................................I第 1 章 绪论..................................................................................
