28、M=6XM16, M=4XM12以上參數(shù)全用 黑體或黑體字表示，見上表。點(diǎn)澆口 D型模架，模板 W 350, L = 450, A= 80, B!= 90, C= 100的標(biāo)準(zhǔn)模架標(biāo)記為:模架 DD3545-80 x 90X100GB/T12555 2006其相應(yīng)的各個尺寸為：W=450, W=63, W=220, VW=164, W=196, W=284, W=285;L1=426, L 2=390, L5=244, L6=312, L?=384;H=30, H2=45, H3=35, H4=45, H5=20, H=25;D=30, D=25, M=6XM16, M=4XM1。以上參數(shù)全用

29、 黑體或黑體字表示，見上表。7 .2 模架的選型模具的大小主要取決于塑件的大小和結(jié)構(gòu)，對于模具而言，在保證足夠強(qiáng)度和剛度的條件下，結(jié)構(gòu)以緊湊為好。對學(xué)生來說設(shè)計(jì)還沒有經(jīng)驗(yàn)，現(xiàn)介紹兩種標(biāo)準(zhǔn)模架選型的經(jīng)驗(yàn)方法。(1)根據(jù)塑件在分型面上投影的面積或模仁周邊尺寸，以塑件布置在推桿推出范圍之內(nèi)及復(fù)位桿與型腔或模仁邊緣保持一定距離為原則來確定模架大小。(7 D(7-2)塑件投影寬度 W W310塑件投影長度LL2 D2（復(fù)位桿直徑）30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7 4根據(jù)上兩式可求得 W3和L2這兩個參數(shù)，再對照標(biāo)準(zhǔn)模架尺寸系

30、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, 300L2 D2（復(fù)位桿直徑）30可求得W3 20010210 ,于是查表7 4 得W3220 ,因此 W 350, D225。L2300 D230300 2530355，查表 7 4 選 l2390 ,因此得 L 450 故所選模架為L 350450,DAM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7-57-8與表中數(shù)據(jù)。圖7-
