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、
2、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）IICover Injection Mold AbstractThe graduation design topic of cover for injection mold design, mainly in the plastic parts for forming based on the analys
