| titleOfInvention | Manufacturing method of collapsible sand core |
| abstract | (57) [Summary] [Purpose] To obtain a sand core that can be sufficiently coated and has excellent disintegration even with a sand core prototype that has been solidified using the warm box method. [Structure] A sand core prototype obtained by heating sand with a furan-based resin and a curing agent for heat curing of the resin and solidifying the sand core prototype is subjected to alkali treatment to obtain a sand core prototype. The child mold is heated and dried, washed with water, treated with an organic acid salt, dried, and then immersed in a coating solution to uniformly coat the surface of the sand core mold, and then dried to disintegrate sand. Get the core. |
