Abstract

The device comprises a filling assembly (6) with a storage hopper (3) for molding material (2), an outlet member (4) for discharging the molding material (2) into the shooting head (1), and a gate (5) for closing the outlet member (4), the filling assembly (6) being mounted for vertical movement on a machine frame (7) for purposes of immersing the outlet member (4) into the shooting head (1) that is to be filled. To ensure that, on the one hand, the filling assembly (6) is filled with the molding material (2) in an accurately predeterminable and reproducible manner and that, on the other hand, the filling level of the filling assembly (6) is accurately determined, the device is designed and constructed such that a weighing device (8) for determining the weight of the filling assembly (6) is arranged between the filling assembly (6) and the machine frame (7).
