style="text-indent:25px">擠出模又稱擠出機頭。這種模具能連續(xù)生產(chǎn)斷面形狀相同的塑料，例如塑料管材、棒材、片材等。擠出機的加熱加壓的裝置與注射機的裝置相同。熔融狀態(tài)的塑料經(jīng)過機頭會形成連續(xù)不斷的成型塑件，生產(chǎn)效率特別高。模具澆口的尺寸及位置選擇應(yīng)避免產(chǎn)生噴射和蠕動現(xiàn)象。小的模具澆口如果正對著一個寬度和厚度較大的型腔，則高速料流經(jīng)過澆口時，由于受到很高的切應(yīng)力，將生產(chǎn)噴射和蠕動等熔體斷裂現(xiàn)象。有時噴著現(xiàn)象還會使塑料制件形成波紋流痕。模具澆口位置的選擇應(yīng)使塑料的流程比較短，料流變化方向比較少。模具澆口位置的選擇應(yīng)有利于型腔內(nèi)氣體的排出。應(yīng)防止料流將型腔，型芯，嵌件擠壓變形。汽車車身上的的沖壓件大體上分為覆蓋件、梁架件和一般沖壓件。</p><div
