Abstract
1. Кокиль для литья лопастей корабельных гребных винтов из титановых сплавов, содержащий разъемные полукокили с ребрами жесткости, узлы крепления и кантования кокиля, рабочую полость для получения отливки, литниковую систему, периклазовые (керамические) стержни для формирования прибыли и стояка и расчлененный по вертикальному и горизонтальному разъемам, отличающийся тем, что его вертикальный разъем выполнен криволинейным по винтовой линии кромок лопасти, геометрия которой определена изменяющимся шагом лопасти, а вдоль этой винтовой линии с наружной стороны входящей и выходящей кромок лопасти по всему периметру стенки кокиля расположены равномерно в литых пазах узлы крепления и проходящий по линии изменения шага лопасти поясок смыкания в виде буртика шириной, меньшей толщины стенки кокиля, и равной от 2 до 2,5 радиусов кромки отливки лопасти высотой, составляющей от 0,3 до 0,4 от ширины пояска, и длиной, равной длине винтовой линии криволинейного разъема, за пояском смыкания в месте разъема кокиля в продолжении части кокиля сформировано углубление высотой (глубиной) от 0,4 до 0,5 от ширины пояска, шириной от 0,5 до 0,6 от ширины пояска и длиной, равной по длине пояску смыкания, которое после сборки половин кокиля заполнено формовочной смесью (керамической массой), а кокиль разделен по горизонтальному обрабатываемому разъему на примерно 2-е равные части таким образом, что рабочая полость кокиля расположена в положении, при котором в горизонтальной плоскости этого разъема, проходящей через ось лопасти, шаговый угол между первым и последним радиальным сечением лопасти разделен пополам, причем толщина стенки рабочей поверхности кокиля равна в местах о1. Chill for casting the blades of ship propellers made of titanium alloys, containing detachable semi-cockles with stiffeners, attachment and tilting units of the chill mold, a working cavity for casting, the gating system, periclase (ceramic) rods for profit and riser, and divided into vertical and horizontal connectors, characterized in that its vertical connector is made curved along the helical line of the edges of the blade, the geometry of which is determined by the changing pitch of the blade, and along this screw On the outside of the inlet and outlet edges of the blade around the entire perimeter of the chill wall, the attachment points and the closing girdle passing along the line of the blade pitch change in the form of a collar in the form of a shoulder with a width smaller than the chill wall thickness and equal to from 2 to 2.5 edge radii castings of a blade with a height of 0.3 to 0.4 from the width of the girdle and a length equal to the length of the helix of the curved connector, a recess in height (depth) from 0.4 to 0.5 of the width of the girdle, a width of 0.5 to 0.6 of the width of the girdle and a length equal to the length of the closure girdle, which, after assembly of the halves of the chill mold, is filled with molding sand (ceramic mass), and the chill mold is divided approximately by horizontal connector 2 equal parts in such a way that the working cavity of the chill mold is located in a position in which in the horizontal plane of this connector passing through the axis of the blade, the step angle between the first and last radial section of the blade is divided in half, and the wall thickness of the working the surface of the chill mold is equal in places about
