Description

Изобретение относитс  к литейному производству , а именно к литниковым системам, и может использоватьс  дл  заливки литейных форм различными сплавами. Наиболее близкой по технической сущности и достигаемому эффекту к предлагаемой  вл етс  ступенчата  литникова  система , включающа  сто к, питатели, примыкающие к нему на разных уровн х, и металлические .щары 1. В ней последовательный ввод в работу питателей и их перекрытие осуществл етс  путем забрасывани  металлических щаров в сто к при заливке формы. Дл  безопасности щары перед забрасыванием необходимо, греть, что требует наличи  нагревательного устройства на месте- заливки , кроме того, сложно фиксировать момент перекрыти . . -; Цель изобретени  - обеспечить автоматическое перекрытие питателей. . Это достигаетс  тем, что все питатели, кроме нижнего, выполнены из газифицируемого материала, наклонены в сторону сто ка вниз, а огнеупорные шары установлены в питател х. На чертеже дана схема предлагаемой ступенчатой литниковой системы. Литникова  система состоит из сто ка 1, имеющего по высоте разные диаметры, питателей 2, 3 и 4, примыкающих к сто ку и форме 5 на разнь1х уровн х, и огнеупорных щаров 6 и 7, которые заформованы в питатели верхних уровней. Последние выполн ют из легких полимерных материалов, таких как пенополистирол, пенополиуретан и т,, п. В питателе высекают  чейку, в которой располагают металлический щар, и затем закрывают ее пробкой из материала питател . Выщесто щие питатели устанавливают наклонно к сто ку дл  свободного выпадени  щаров в сто к. Литникова  система работает следующим образом. При заливке металл, поступающий в сто к 1, через питатель 2 начинает заполн ть форму 5. Стру  металла в сто ке  вл етс  источником тепловой энергии , под воздействием которого происходит расплавление и газификаци  питателей 3 и 4. Когда питатель 3 расплавитс  до места внедрени  щара, последний ввиду отсутстви  преп тстви  The invention relates to foundry, namely gating systems, and can be used for casting molds with various alloys. The closest in technical essence and the achieved effect to the proposed is a stepped gating system, including a hundred, feeders adjacent to it at different levels, and metal gates 1. In it, the serial commissioning of the feeders and their overlapping is performed by throwing metal spheres in a hundred to when casting. For safety, shcharas need to be warm before throwing, which requires the presence of a heating device at the filling site, and it is also difficult to fix the moment of overlap. . -; The purpose of the invention is to provide automatic overlapping of feeders. . This is achieved by the fact that all the feeders, except for the lower one, are made of the gasifying material, are inclined in the direction of a hundred and down, and the refractory balls are installed in the feeders. The drawing is a diagram of the proposed stepped gating system. The litnik system consists of a stand 1, having different diameters in height, feeders 2, 3, and 4, adjacent to the sink and form 5 at different levels, and refractory bows 6 and 7, which are molded into feeders of the upper levels. The latter are made of lightweight polymeric materials, such as polystyrene foam, polyurethane foam, and so on. In the feeder, a cell is cut in which the metal core is located, and then it is closed with a stopper made from the feeder material. The feeder feeders are set obliquely to the sink for free deposition of slots in a hundred kilograms. The runner system works as follows. When pouring, the metal entering a hundred to 1 through the feeder 2 begins to fill the form 5. The metal stream in the stand is a source of thermal energy, under the influence of which melting and gasification of the feeders 3 and 4 occurs. When the feeder 3 melts to the point of injection the latter due to the absence of an obstacle
