ABSTRACT:
A device for filling molds with a casting resin or the like. An elastic casting container, with at least one fill and discharge opening, is arranged in the pressure box, which casting container selectively receives the casting resin therein from a feed pipe and delivers the casting resin to the mold through a fill pipe. The casting container is emptied by a pressure buildup inside of the pressure box, either by means of a gaseous or a liquid pressure medium. In this manner, the casting container can be loaded with the casting resin such that a renewed gas loading of the already degassed casting resin prior to the filling of the mold no longer occurs, while simultaneously limiting cleaning operations.
