style="text-indent:25px">汽車注射模注射模又稱注塑模。這種模具的成型工藝特點(diǎn)是，將塑原材料放置在注射機(jī)的加熱料筒內(nèi)。塑料受熱熔融，在注射機(jī)的螺桿或柱塞推動(dòng)下，經(jīng)噴嘴和模具的澆注系統(tǒng)進(jìn)入模具型腔，塑料在模具型腔內(nèi)經(jīng)保溫、保壓、冷卻固化成型。由于加熱加壓裝置能夠分階段發(fā)揮作用，注射成型不但能成型形狀復(fù)雜的塑料制件，而且生產(chǎn)效率高、質(zhì)量好。故注射成型在塑料制件成型中占有很大的比重，注射模占塑料成型模具的一半以上。注射機(jī)主要用于熱塑性塑料的成型，近年來(lái)也逐漸用于熱固性塑料的成型。靖江汽車模具制造汽車模具與沖壓線機(jī)床噸位和工作臺(tái)面基本匹配，暫不需改善。</p><div
