30、影宽度（71）塑件投影长度（72）式中常数10为推杆边缘与垫块之间的双边距离，参见表7430为复位杆与型腔或模仁边缘之间的双边距离，参见表74根据上两式可求得和这两个参数，再对照标准模架尺寸系列中相应参数就可以大致确定模架大小和型号了。当然在设计过程中还要考虑到冷却水道、抽芯机构和顺序分型等机构的布置，有可能所选模架还要加大。例：有一塑件型腔平面尺寸为200mm×300mm，决定用点浇口，塑件用推杆推出，试选择模架。解：根据经验公式（71）、（72）得：模板有效使用面积，可求得，于是查表74得，因此，。,查表74选，因此得，故所选模架为，DA型模架(带支承板)。(2) 为节约模具钢材和便于热处理，根据产品的外形尺寸（平面投影面积与高度），以及产品本身结构，可以确定镶件（模仁）的外形尺寸，确定镶件的尺寸后，也就确定模架的大小了。 普通塑件模具模架与镶件（模仁）大小的选择，可参考图7-8与
