摘 要 注塑成型制品质量控制方面存在的困难主要来源于力学的复杂性和在温度、压力波动下材料行为的不可预测性，研究工艺参数对注塑制品质量的影响关系，建立工艺参数与制品质量之间的关系模型，并用DOE法对工艺进行仿真优化是注塑制品工艺优化的前提。 本文选用半结晶型和无定型ABS两种材料，针对一维流动平板两个方向上的收缩、强度，熔接线强度、制品重量及沉降斑等质量指标进行了实验研究。研究了工艺参数对质量指标的影响及因素之间的交互作用。本文主要工作包括以下几方面: 1 工艺参数对制品质量的交互影响分析；2 应用DOE法结合析因分析结果；3.CAE技术结合DOE法进行设计，并用MOLDFLOW进行仿真分析，为质量控制技术提供了工艺模型。 关键词: 注塑成型，正交实验，Moldflow，三维建模，工艺仿真优化，实验设计 Abstract Quality control of injection molding products, mainly difficulties from that exist in the complexity of process dynamics and in the temperature and pressure fluctuations unpredictable behavior of materials, of process parameters on product quality of injection molding between the relationship，DOE method with simulation and optimization technology of injection molding products, process optimization is a prerequisite. Semi-crystalline and amorphous ABS we usd in this paper，For a flat that two-dimensional flow direction shrinkage, strength, weld line strength, weight and sink marks and other products, the quality indicators studied. In this paper, include the following：1. Process parameters on product quality of interaction analysis；2. Application of DOE method with the results of factorial analysis；3. CAE design method combined with DOE，Simulation and analysis with MOLDFLOW，quality control technology provides for the process model. Key words：Injection Molding，Orthogonal,Moldflow，Three-dimensional modeling，Process simulation and optimization，design of experiment. 目录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc263675964 1.1 引言 PAGEREF _Toc263675964 \h 1 HYPERLINK \l _Toc263675965 1.2 注塑成型工艺过程简介 PAGEREF _Toc263675965 \h 1 HYPERLINK \l _Toc263675966 1.3注塑成型工艺的发展趋势 PAGEREF _Toc263675966 \h 2 HYPERLINK \l _Toc263675967 1.4 注塑成型工艺优化国内外研究概况 PAGEREF _Toc263675967 \h 4 HYPERLINK \l _Toc263675968 1.5本文主要工作内容及其意义 PAGEREF _Toc263675968 \h 6 HYPERLINK \l _Toc263675969 2. 注塑成型工艺参数影响性分析 PAGEREF _Toc263675969 \h 8 HYPERLINK \l _Toc263675970 2.1 压力参数分析 PAGEREF _Toc263675970 \h 8 HYPERLINK \l _Toc263675971 2.
