端盖塑料模具毕业设计1

洛阳理工学院毕业设计（论文）I端盖注塑模具设计摘要本次毕业设计的课题为端盖注塑模具设计，主要在对塑件进行成型分析的基础上从原材料分析、成型特性、分型面的选择、浇注系统的设计、冷却系统的设计、型芯和型腔的结构设计、推出复位结构设计、侧向抽芯机构的设计和导向机构的设计等多方面详细阐述了端盖注塑模具的设计过程。同时通过合理地选择注射机并对注塑压力、最大注塑量、锁模力、开模行程等相关方面进行校核，进一步保证设计的合理型，并设计温度调节系统和阐述模具装配等方面。本课题最大的特点是模具由左右侧滑块组成，设计的模具结构合理，加工方便，工艺性好，能较好地运用于实际生产。同时，在设计过程中，通过查阅大量资料、手册、标准、期刊等，结合教材上的知识也对注塑模具的组成结构（成型零部件、浇注系统、导向部分、推出机构、排气系统、模温调节系统）有了系统的认识，拓宽了视野，丰富了知识，为将来独立完成模具设计积累了一定的经验。关键词：端盖注塑模具，侧向抽芯，分型面，注塑模具，注射机洛阳理工学院毕业设计（论文）IICoverInjectionMoldAbstractThegraduationdesigntopicofcoverforinjectionmolddesign,mainlyintheplasticpartsforformingbasedontheanalysisoftherawmaterialanalysis,frommoldingcharacter,classification,theselectionofthedesignofgatingsystem,coolingsystemdesign,coresandmoldstructuredesign,structuredesign,launchedresetlateralcore-pullingmechanismdesignandthedesignofsteeringmechanismandsoonvariousexplainsindetailthedesignprocessofthecoverinjectionmold.Atthesametimethroughthereasonableselectionofinjectionmachineandtheinjectionpressure,maximuminjectionquantity,clampingforce,openmoldstrokeaswellasrelatedaspectsofchecking,furtherassurerationaldesignofthetype,anddesigntemperaturecontrolsystemandexpoundsthemoldassembly,etc.Thissubjectisthebiggestcharacteristicistomouldaleftlateralspreadspieceofcomposition,thedesignofdiestructureisreasonable,processingisconvenient,goodinusabilityandcanbewellappliedtopracticalproduction.Meanwhile,inthedesignprocess,accesstoalargenumberofdata,manuals,standard,periodicals,combinedwiththeknowledgeonteachingmaterialofinjectionmoldscompositionstructure(moldingparts,injectionsystem,guidingparts,launchinstitutions,exhaustsystems,moldtemperatureadjustingsystem)havetheunderstandingofthesystem,widenthevision,richknowledge,forfutureindependentcompletedmolddesignaccumulatedacertainamountofexperience.KEYWORDS:coverinjectionmolds,sidecore-pulling,thepartingsurface,injectionmould,injectionmachine洛阳理工学院毕业设计（论文）III目录前言..................................................................................................1第1章塑料注射模具的设计步骤和结构组成..............................31.1塑料注射模具的设计步骤及内容.......................................31.1.1接受任务书...................................................................31.1.2收集、分析、设计原始资料.........................................31.1.3确定成型方法................................................................41.1.4选择成型设备................................................................41.1.5确定模具类型的主要结构方案.....................................41.1.6绘制模具图....................................................................41.2塑料注射模具的结构组成和作用........................................6第2章塑件的工艺分析...................................................................72.1塑件成型工艺分析.............................................................72.1.1材料的性能....................................................................82.1.2成型特性及条件............................................................82.1.3结构工艺性....................................................................92.1.4零件体积及质量估算....................................................92.2ABS的成型特性与工艺参数..............................................92.2.1塑料成型工艺参数.....................................................92.3选择注射机..........................................错误!未定义书签。2.4注射机的校核...................................................................11第3章塑件工艺尺寸计算.............................................................133.1型芯和型腔.......................................................................133.1.1型芯和型腔的结构...................................................133.1.2型芯和型腔的尺寸...................................................13第4章塑件在模具的位置和浇注系统的设计..............................154.1确定型腔的数量................................................................154.2分型面的选择....................................................................16洛阳理工学院毕业设计（论文）IV4.3浇注系统的设计................................................................174.3.1主流道设计...............................................................174.3.2分流道设计................................................................184.3.3浇口的设计...............................................................204.3.4冷料穴的设计...........................................................214.3.5排气系统的设计.......................................................224.4侧向分型与分型机构的设计.............................................224.4.1斜导柱的设计...........................................................224.4.2侧滑块的设计...........................................................214.4.3楔紧块的设计...........................................................234.4.4侧滑块定位装置的设计............................................24第5章结构零部件的设计.............................................................255.1定位圈的设计...................................................................255.2拉料杆的设计...................................................................255.3浇注系统的主流道...........................................................255.4推出机构...........................................................................255.4.1推出机构的作用和种类.....................
