所述的一种可组合式易割片的制造方法为，在模具上做出砂型易割片本体101的腔体，并在模具上设计出能够成型为圆形沉孔102、漏斗形通孔103、扇形沉孔104的凸台，将制作砂型易割片的原材料在此模具上成型，生产出砂型易割片组件1，另外设计一模具，在模具上开设能够成型为环形连接片201、漏斗形冒口202、扇形连接片203、内翻边结构204的腔体，在此模具上注入所需熔融金属液，成型为金属易割片组件2，将金属易割片组件2上的扇形连接片203下表面粘贴在砂型易割片组件1的扇形沉孔104表面上，可组合式易割片在静压造型线上的使用方法与普通砂型易割片的使用方法相同，可组合式易割片在高压造型线上的使用方法与普通金属易割片的使用方法相同。
本具体实施方式的工作原理：在模具上做出砂型易割片本体的腔体，并在模具上设计出能够成型为圆形沉孔、漏斗形通孔、扇形沉孔的凸台，将制作砂型易割片的原材料在此模具上成型，生产出砂型易割片组件，另外设计一模具，在模具上开设能够成型为环形连接片、漏斗形冒口、扇形连接片、内翻边结构的腔体，在此模具上注入所需熔融金属液，成型为金属易割片组件，将金属易割片组件上的扇形连接片下表面粘贴在砂型易割片组件的扇形沉孔表面上，在静压造型线上，在通常放置砂型易割片的位置放置可组合式易割片，在静压造型线让熔融的金属液成型，金属液定型到一定程度后形成金属件，静压造型线压金属易割片组件底部，金属易割片组件变形到一定程度后，金属易割片组件撑破砂型易割片组件，砂型易割片组件对金属易割片组件起到一定的保温作用，金属易割片组件慢慢冷却，金属件成型后，去掉冒口，在高压造型线上，在通常放置金属易割片的位置放置可组合式易割片，在高压造型线让熔融的金属液成型，金属液定型到一定程度后形成金属件，高压造型线压金属易割片组件底 部，金属易割片组件变形到一定程度后，金属易割片组件撑破砂型易割片组件，砂型易割片组件对金属易割片组件起到一定的保温作用，金属易割片组件慢慢冷却，金属件成型后，去掉冒口。
本发明的有益效果在于：1、可组合式易割片具有保温功能，在静压造型上使用不会出现冒口糊口，可组合式易割片在高压造型线上使用受高压冲击不会损坏，可组合式易割片在静压造型和高压造型线上能够通用。2、漏斗形冒口下部突出所述砂型易割片本体下表面，金属易割片组件被压缩变形后，防止砂型易割片组件先碎裂，碎裂的砂型易割片组件进入铸件型腔。3、砂型易割片本体下端设置内翻边结构，便于铸件上配合使用的冒口底部冷凝、收缩。4、砂型易割片本体上表面均布开设三个扇形沉孔，且所述砂型易割片本体开设的所述扇形沉孔内侧与所述圆形沉孔外侧重合设置，所述环形连接片外侧壁均布固定设置三个扇形连接片，且所述扇形连接片数量与所述扇形沉孔的数量相同，所述环形连接片上的所述扇形连接片下表面与所述砂型易割片本体上的所述扇形沉孔上表面粘贴设置，防止金属易割片组件受力后转动。
本发明的具体实施例不构成对本发明的限制，凡是采用本发明的相似结构及变化，均在本发明的保护范围内。
