Литниково-питающая система оболочковых форм в литье по выплавляемым моделям, включающая литниковую воронку, стояк, питатели и зумпф, отличающаяся тем, что зумпф выполнен в виде половины тора с эллиптическим сечением, большая ось которого направлена параллельно вертикальной оси стояка.The gate-feeding system of shell molds in investment casting, including the gate funnel, riser, feeders and sump, characterized in that the sump is made in the form of a half torus with an elliptical cross section, the large axis of which is parallel to the vertical axis of the riser. Реализация изобретения позволяет понизить брак оболочковых форм при заливке металлом и, как следствие, отливок по неметаллическим включениям.The implementation of the invention allows to reduce the marriage of shell molds when casting with metal and, as a consequence, castings for non-metallic inclusions.
