xx理工学院毕业设计 Institute of Technology East China Jiaotong University Graduation Design 题 目 嵌件调压螺母注塑模设计 100 摘 要 本设计主要讲述对进行模具设计。模具设计前，必须对产品进行分析，了解产品的结构、用途、性能、表面质量和美观效果等因素，选择合适的材料，从而根据产品规格尺寸进行模具设计，校核注塑模与注射机的关系，设计一套合理的模具。本次设计，综合了大学三年所学的专业知识，更明确地了解整套模具在设计过程中的机理进一步巩固模具有关知识清楚地认识到作为一名模具设计人员必须要具备的素质和责任。Abstract My?project?is?mainly?about?the?plastic?pattern?design?for?the?support.?In?order?to?design?a?nest?appropriate?pattern,?first,?we?must?analysis?the?product?seriously,?from?which?we?can?know?the?structure,?use,?cap?ability,?external?quality?and?effect.?Then?choose?appropriate?material?and?check?and?ratify?the?relation?between?the?in?the?injection?pattern?and?the?injection?machine,?according?to?the?product?specification?and?size. This is a major injection mold design, is a plastic clip die design, the entire design process to take into account products to be closer to market needs and design practical, affordable, beautiful shape, quality and so on reasonable request. Design of the first analysis of technology products and then die-and the choice of parts an die structure, and then calculate and check the data. In the design of the draw should also carry out the mold and structural plans prepared statement.
