30、影寬度（71）塑件投影長度（72）式中常數(shù)10為推桿邊緣與墊塊之間的雙邊距離，參見表7430為復(fù)位桿與型腔或模仁邊緣之間的雙邊距離，參見表74根據(jù)上兩式可求得和這兩個參數(shù)，再對照標(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了。當(dāng)然在設(shè)計(jì)過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200mm×300mm，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)驗(yàn)公式（71）、（72）得：模板有效使用面積，可求得，于是查表74得，因此，。,查表74選，因此得，故所選模架為，DA型模架(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
