矿泉水瓶盖注塑模具改进设计.docVIP

陕西理工学院毕业论文 PAGE \* MERGEFORMATV 基于PRO/E矿泉水瓶盖注塑模具改进设计 [摘要] 此次设计是对矿泉水瓶盖注塑模的设计，包括对它的工艺分析，材料性能，设备选择，尺寸计算等内容。由于此塑件内部有螺纹，所以主要解决了塑件脱模方式的选择，脱模机构的设计，型腔的设计，以及模腔数目的确定等问题。经过对比采用螺牙旋转出模具，已达到预期目的。 [关键词]：注塑模，脱模机构，螺纹 Improvement Based on PRO/E mineral water bottle injection Molds Abstract : The design is a mineral water bottle injection mold design, including its process analysis, material properties, equipment selection, sizing and so on. Because inside this plastic parts are threaded, so the main choice to solve the plastic stripping methods, design releasing mechanism, cavity design, and mold cavity to determine the number of other issues. After comparing the use of thread rotated out of the mold, it has reached the intended purpose. Key words: Injection mold, ejection mechanism, thread 目录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc421808169 摘要 PAGEREF _Toc421808169 \h I HYPERLINK \l _Toc421808170 Abstract PAGEREF _Toc421808170 \h II HYPERLINK \l _Toc421808171 1 前言 PAGEREF _Toc421808171 \h 1 HYPERLINK \l _Toc421808172 2 塑件的工艺分析 PAGEREF _Toc421808172 \h 2 HYPERLINK \l _Toc421808173 2.1 塑件的型工艺分析 PAGEREF _Toc421808173 \h 2 HYPERLINK \l _Toc421808174 2.1.1 壁厚分析 PAGEREF _Toc421808174 \h 2 HYPERLINK \l _Toc421808175 2.1.2 圆角分析 PAGEREF _Toc421808175 \h 3 HYPERLINK \l _Toc421808176 2.2 塑件材料的选择及材料特性 PAGEREF _Toc421808176 \h 3 HYPERLINK \l _Toc421808177 2.2.1 材料的选择 PAGEREF _Toc421808177 \h 3 HYPERLINK \l _Toc421808178 2.2.2 材料特性 PAGEREF _Toc421808178 \h 3 HYPERLINK \l _Toc421808179 2.3 方案选择 PAGEREF _Toc421808179 \h 4 HYPERLINK \l _Toc421808180 3 注射设备的选择 PAGEREF _Toc421808180 \h 6 HYPERLINK \l _Toc421808181 3.1 估算塑件的体积和质量 PAGEREF _Toc421808181 \h 6 HYPERLINK \l _Toc421808182 3.2 选择注射机 PAGEREF _Toc421808182 \h 6 HYPERLINK \l _Toc421808183 3.3 注塑机相关参数的校核 PAGEREF _Toc421808183 \h 7 HYPERLINK \l _Toc421808184 3.3.1 最大注射量的校核 PAGEREF _Toc421808184 \h 7 HYPERLINK \l _Toc421808185 3.3.2 注射压力的校核 PAGEREF _Toc421808185 \h 7 HYPERLINK \l _
