29、 黑体或黑体字表示，见上表。7 .2 模架的选型模具的大小主要取决于塑件的大小和结构，对于模具而言，在保证足够强度和刚度的条件下，结构以紧凑为好。对学生来说设计还没有经验，现介绍两种标准模架选型的经验方法。(1)根据塑件在分型面上投影的面积或模仁周边尺寸，以塑件布置在推杆推出范围之内及复位杆与型腔或模仁边缘保持一定距离为原则来确定模架大小。(7 D(7-2)塑件投影宽度 W W310塑件投影长度LL2 D2（复位杆直径）30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7 4根据上两式可求得 W3和L2这两个参数，再对照标准模架尺寸系

30、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200mm300mm决定用点浇口，塑件用推杆推出，试选择模架。解：根据经当公式（71）、（7-2）得：模板有效使用面积200W310, 300L2 D2（复位杆直径）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 选 l2390 ,因此得 L 450 故所选模架为L 350450,DAM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7-57-8与表中数据。图7-
