毕业设计（论文）-风扇调速器上盖射模设计（全套图纸）.docVIP

PAGE IIPAGE I摘要本塑件是风扇调速器上盖，为盒类结构，较为简单。内表面为哑光，生产批量大，为了保证生产批量，提高生产效率以及降低生产成本，采用一模两腔成型结构。该模具的设计特点是：为了满足中小型塑件的成型要求，采用了侧浇口浇注系统、一模两腔的结构，为了保证塑件的质量，两腔均衡地布置在两侧。采用一次分型，一次推出推杆推出机构，使模具结构得到简化。利用Pro/E、AutoCAD等计算机辅助设计软件对塑件进行三维建模，初步模具设计，以及绘画装配图和零件图，简化了模具设计的过程。关键词：风扇调速器、模具设计、侧浇口、一模两腔全套图纸加153893706PAGE IIAbstract This plastic part is fan governor cover, structure, relatively simple. The inner surface of matte, mass production, in order to ensure production volume, improve production efficiency and reduce production cost, using a mold two cavity forming structure. The mold design features: In order to meet the needs of medium-sized plastic molding, using a side gate gating system, one mold two cavity structure, in order to guarantee the quality of plastic parts, the two cavity balanced layout on both sides. Using one type, a push rod pushing mechanism, make the mold structure be simplified.Using Pro/E, AutoCAD computer aided design software in plastic parts for 3D modeling, preliminary mold design and draw the assembly drawing and parts drawing, simplifies the process of mold design.Keywords: fan governor mold design side gate a mold two cavity目录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc496085541 摘要 PAGEREF _Toc496085541 \h I HYPERLINK \l _Toc496085542 Abstract PAGEREF _Toc496085542 \h II HYPERLINK \l _Toc496085543 第一章 绪论 PAGEREF _Toc496085543 \h 1 HYPERLINK \l _Toc496085544 1.1引言 PAGEREF _Toc496085544 \h 1 HYPERLINK \l _Toc496085545 1.2风扇调速器上盖注塑模具设计的意义 PAGEREF _Toc496085545 \h 2 HYPERLINK \l _Toc496085546 1.3风扇调速器上盖注塑模具设计的特点 PAGEREF _Toc496085546 \h 2 HYPERLINK \l _Toc496085547 第二章 塑件成型工艺性分析 PAGEREF _Toc496085547 \h 3 HYPERLINK \l _Toc496085548 2.1塑件的分析 PAGEREF _Toc496085548 \h 3 HYPERLINK \l _Toc496085549 2.1.1外形尺寸 PAGEREF _Toc496085549 \h 3 HYPERLINK \l _Toc496085550 2.1.2精度等级 PAGEREF _Toc496085550 \h 3 HYPERLINK \l _Toc496085551 2.1.3脱模斜度 PAGEREF _Toc496085551 \h 3 HYPERLINK \l _Toc496085552 2.2材料的选择 PAGEREF _Toc496085552 \h 4 HYPERLINK \l _Toc496085553 2.3PP的性能分
