摘要
这次设计的课题是针对一个塑料制成的储物箱,通过三维软件UG、等软件,对注塑零件盖进行3D软件建模,另外,在此基础上,设计人员还对模具的成型结构进行了设计,并绘制出相关的装配图、零件图。在结构设计过程中,经过方案对比,选定采用了一模一腔的设计。本次设计的模具具有工作稳定、结构紧凑、在冷却方面我们采用了随形冷却管道,因为随形的冷却管道具形状复杂,普通的机加工机床无法加工,所以我们采用了3D金属打印的技术来进行制造模具的成型零件等多种特点,最后除了模具结构的设计外,选择了XS-ZY-2000型号的注塑成型机,还对模具的进行了分型面、型腔数目、直接浇注系统、脱模机构、冷却系统等进行了详细的设计。
本次设计主要根据任务书所给的注塑零件盖来进行模具的设计,自主选择的研究产品是储物箱,先利用UG对储物箱进行3D建模,然后根据相应的参数对应选择注射机的型号,并对塑料制品的模架结构进行了设计,对模具参数进行校核,完成了浇注系统和型腔排布的设计,同时还完成了装配图和零件图的设计。在检验过程中需要仔细核对细节,避免发生模具设计不合理、零件干涉等错误的发生。
关键词:储物箱;模具设计;CAD绘制二维图;UG绘制3D图。
