29、這兩個(gè)參數(shù)，再對(duì)照標(biāo)準(zhǔn)模架尺寸系列中相應(yīng)參數(shù)就可以大致確定模架大小和型號(hào)了。當(dāng)然在設(shè)計(jì)過(guò)程中還要考慮到冷卻水道、抽芯機(jī)構(gòu)和順序分型等機(jī)構(gòu)的布置，有可能所選模架還要加大。例：有一塑件型腔平面尺寸為200mm300mm決定用點(diǎn)澆口，塑件用推桿推出，試選擇模架。解：根據(jù)經(jīng)當(dāng)公式（71）、（7-2）得：模板有效使用面積200W310,300L2D2（復(fù)位桿直徑）30可求得W320010210,于是查表74得W3220,因此W350,D225。L2300D2303002530355，查表74選l2390,因此得L450故所選模架為L(zhǎng)350450,D遜模架（帶支承板（2）為節(jié)約模具鋼材和便于熱處理，根據(jù)產(chǎn)品的外形尺寸（平面投影面積與高度）,以及產(chǎn)品本身結(jié)構(gòu)，可以確定鑲件（模仁）的外形尺寸，確定鑲件的尺寸后，也就確定模架的大小了。普通塑件模具模架與鑲件（模仁）大小的選擇，可參考圖7-8與表7-5中數(shù)據(jù)。圖7-8采用鑲件的模架結(jié)
