Abstract (en)
The present invention relates to a machine and method for manufacturing sand cores, the machine (100) comprising a molding box (1), a blowing chamber (2), a gassing element (3) and a blowing assembly (4) which is suitable for injecting air against the blowing chamber (2) and for suctioning it through a filtration plate. The blowing chamber (2) is filled with sand and is arranged in an unloading position between the blowing assembly (4) and the molding box (1) for unloading the sand into the molding box (1); and the gassing element (3) is subsequently arranged between the blowing assembly (4) and the molding box (1). The machine (100) further comprises cleaning means (6) suitable for cleaning the filtration plate once the blowing chamber (2) has left the unloading position.
