Abstract

1. Способ вакуумирования литейных форм, используемый в процессе вибро-центробежного литья, отличающийся тем, что над литейной формой создают область вихревого пространства переменно-пониженного давления, разрежение осуществляют в зоне зауженного щелевого канала, которую образуют между волновой плоскостью дискообразного экрана и поверхностью литейной формы.2. Устройство для вакуумирования, содержащее раму с литейной формой, заливочную воронку и желоб, отличающееся тем, что в него введен дискообразный экран с волновой поверхностью по размеру формы с центральным отверстием под воронку, вокруг которой размещен коллектор с щелевым соплом для продувки зоны зауженного щелевого канала, которая образована между поверхностями дискообразного экрана и литейных форм.1. The method of evacuation of casting molds used in the process of vibro-centrifugal casting, characterized in that a region of vortex space of variable-reduced pressure is created above the casting mold, rarefaction is carried out in the area of the narrowed slot channel formed between the wave plane of the disk-shaped screen and the surface of the mold .2. A vacuum device comprising a frame with a casting mold, a pouring funnel and a chute, characterized in that a disk-shaped screen with a wave surface of the size of the mold with a central hole for the funnel is placed around which a collector with a slot nozzle is placed to purge the narrowed slot channel, which is formed between the surfaces of the disk-shaped screen and the molds.
