50以上，熱處理后變形量小。由于其鑄造性好，且鑄造成本較低，可實(shí)現(xiàn)整體鑄造，減輕鉗工的工作強(qiáng)度，縮短模具的制造周期。止口是模具外觀的重要組成，止口的設(shè)計(jì)以受力均衡為原則，止口又叫虎口，是保證模具定位的。</p><div style="width:100%;text-align: center;"><img style="max-width:

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。啟東汽車模具排行</p></p><br
