Abstract

Изобретение относитс  к литейному производству, в частности к получению отливок методом вакуумной формовки. Цель изобретени  - уменьшение брака отливок по газовым дефектам. Заперта  литникова  система дл  получени  отливок методом вакуумной формовки включает основную воронку 1, сто к 2, вертикальный литниковый ход 3, горизонтальный шлакоуловитель 4, питатели 5, горизонтальный литниковый ход 7, расположенный над уровнем основной воронки 1, дополнительную воронку 8. Площадь поперечного сечени  горизонтального литникового хода 7 меньше, чем площадь узкого сечени  питателей 5. Жидкий металл через основную воронку 1 и сто к 2 поступает в вертикальный литниковый ход 3, далее в горизонтальный шлакоуловитель 4, затем через питатели 5 в полость 6 формы. После заполнени  полости 6 формы выше верхнего уровн  питателей 5 заливку производ т через дополнительную воронку 8 и горизонтальный литниковый ход 7 до полного заполнени  полости 6 формы. Замедленна  заливка верхней части полости 6 формы обеспечит улучшенный газоотвод из сложных стержней. 2 ил.The invention relates to foundry, in particular to the production of castings by vacuum molding. The purpose of the invention is to reduce the casting losses on gas defects. The gating system for producing castings by vacuum forming is turned on. It includes a main funnel 1, one hundred and two, a vertical runner 3, a horizontal slag catcher 4, feeders 5, a horizontal runner 7 located above the main funnel 1, an additional funnel 8. gate 7 is smaller than the narrow area of the feeders 5. Liquid metal through the main funnel 1 and one hundred to 2 enters the vertical gate run 3, then into the horizontal slag catcher 4, then black Without feeders 5 into the cavity 6 forms. After filling the mold cavity 6 above the upper level of the feeders 5, the casting is performed through an additional funnel 8 and a horizontal runner 7 until the cavity 6 is completely filled. Slow pouring of the upper part of the cavity 6 of the mold will provide an improved gas outlet from complex rods. 2 Il.
