<p>The Invention relates to the foundry, in particular, to the casting molds for vacuum molding. A form contains a molding box filled with dry friable filler with a cavity formed in it for filling and cooling the metal, means for sand degassing, at least, one dosing container of movable type and equipped with a tubular pin. The lower tip of the pin isinstalled in the sand in such a manner that casting in the mould is located on the path of motion of refrigerant from the opening of pin to the degassing device. The application of movable measuring container with described modifications simplifies and increases the versatility of accessories.</p> |
