1、拉線盤注射工藝分析及模具設(shè)計(jì)摘 要：注射成型是熱塑性塑料成型的主要方法之一，可以一次成型形狀復(fù)雜的精密塑件。本設(shè)計(jì)進(jìn)行了一款拉線盤的注塑模設(shè)計(jì)，對(duì)零件結(jié)構(gòu)進(jìn)行了工藝分析。確定了分型面、澆注系統(tǒng)等，選擇了注射機(jī)，計(jì)算了成型零部件的尺寸。采用側(cè)澆口。利用直導(dǎo)柱導(dǎo)向，推桿頂料,斜頂桿完成脫模及內(nèi)抽芯方式并對(duì)模具的材料進(jìn)行了選擇。如此設(shè)計(jì)出的結(jié)構(gòu)可確保模具工作運(yùn)用可靠。最后對(duì)模具結(jié)構(gòu)與注射機(jī)的匹配進(jìn)行了校核。并用 autoCAD 繪制了一套模具
