Изобретение относитс  к области литейного производства, а именно к-литью под давлением .The invention relates to the field of foundry, namely casting under pressure.

Известный способ лить  под давлением, включающий заливку жидкого металла з камеру и запрессовку его в прессформу, не позвол ет получать плотные отливки без вакуумировани  прессформы и двойного прессовани .The known method of casting under pressure, which includes pouring the liquid metal from the chamber and pressing it into the mold, does not allow to obtain dense castings without evacuating the mold and double pressing.

С целью улучшени  качества отливок предлагаетс  во врем  прессовани  воздействовать па жидкий металл и камеру сжати  электромагнитным полем.In order to improve the quality of the castings, it is proposed to act on the liquid metal and the compression chamber with an electromagnetic field during pressing.

Сущность изобретени  по сн етс  схемой, где изображена блок-форма в разрезе.The invention is explained in the diagram, which shows a block shape in section.

Блок-форма содержит подвижну О 1 и неподвижную 2 полуформы, индуктор 3 и камеру сжати  4, установленную подвижно в крепежной плите 5 с торцовым зазорол а 0,03+0,3 мм.The block form contains movable O 1 and fixed 2 half-molds, an inductor 3 and a compression chamber 4, which is mounted movably in a mounting plate 5 with an end gap of 0.03 + 0.3 mm.

Согласно предлагаемо.му способу перед заливкой жидкого металла в наполнительный стакан 6 включают индуктор и производ тAccording to the proposed method, before pouring the liquid metal into the filling cup 6, the inductor is inserted and produced

подогрев прессформы. Затем в наполнительный стакан заливают порцию жидкого металла и плунжером 7 осуществл ют его запрессовку в прессформу. При этом камера сжати  4 и наход щийс  в Heii жидкий металл подвергаютс  воздействию переменного электромагнитного пол , благодар  чему на х идкий металл передаютс  упругие колебапи  камеры прессова и) , он перемещаетс  и разогреваетс .heated mold. Then, a portion of the liquid metal is poured into the filling glass and plunger 7 is pressed into the mold. At the same time, the compression chamber 4 and the liquid metal in Heii are exposed to a variable electromagnetic field, due to which elastic oscillations of the press chamber are transferred to the x liquid metal, it moves and heats up.

Вследствие этого замедл етс  кристаллизаци  прессоетатка и увеличиваетс  продолжительность подпресссвки.As a result, the crystallization of the presso-ejector slows down and the duration of the pre-compression increases.
