Abstract
Изобретение относитс к литейному производству, в частности к процессам получени отливок вакуумным всасыванием. Цель изобретени - повышение качества отливок и упрощение технологии. Тигель 10с расплавленным металлом поднимают вверх так, чтобы металлопровод 5 с установленным в нем металлическим стержнем погрузились в расплав на 5-10 мм дл образовани герметичной пробки 6. После извлечени металлического стержн , установки на плиту 2 формы 1 и камеры 3 и подъема камеры 7 в камере 3 создают вакуум , а в камере 7 повышенное давление, затем поднимают вверх тигель 10 с расплавленным металлом, происходит расплавление пробки 6 и заполнение формы 1 расплавом. Намораживание пробки 6 обеспечивает надежную герметизацию металло- провода. 2 ил.The invention relates to foundry, in particular, to processes for producing castings by vacuum suction. The purpose of the invention is to improve the quality of castings and simplify the technology. The crucible 10c with molten metal is lifted upward so that the metal pipe 5 with a metal rod installed in it plunges into the melt by 5-10 mm to form an airtight plug 6. After removing the metal rod, installing it onto the plate 2 of the form 1 and chamber 3 and lifting the chamber 7 into chamber 3 creates a vacuum, and in chamber 7 an increased pressure, then the crucible 10 with the molten metal is lifted upwards, the tube 6 is melted and the mold 1 is filled with melt. Freezing the plug 6 ensures reliable sealing of the metal wire. 2 Il.
