FIELD: foundry, namely, manufacture of castings with internal thread with use of investment patterns. SUBSTANCE: press-mold includes threaded rod having helical grooves on its lateral surface. Threaded sleeve is mounted in intermediate plate; guiding sleeve is mounted in knocking out unit. Guiding sleeve has pins engaging with helical grooves of rod. When press-mold is open knocking out unit moves relative to threaded rod. Guiding sleeve moves in lengthwise direction and pins drive rod to rotation for unscrewing rod out off casting. EFFECT: enhanced reliability of press-mold, increased accuracy of casting profiled articles, enlarged manufacturing possibilities of press-mold. 1 dwg
