ABSTRACT:
An apparatus and method for controlling the filling of mold sections with molten metal is disclosed. The apparatus and method utilize a mold making machine for forming mold sections having a recessed cup on its upper side, a hollow cavity in the interior thereof having a predetermined shape and a passageway interconnecting the hollow cavity and the recessed cup, a conveyor for transporting the mold sections along a predetermined path, a pour vessel including a discharge opening and a valve for controlling the pouring of molten metal from the vessel into the mold sections, a vessel-moving device for positioning the mold section beneath the discharge opening of the vessel, a distance measuring device located above the mold sections and oriented towards the mold sections and operable for measuring the distance to the molten metal level in the recessed cup, and a control device connected to the vessel-moving device, the distance measuring device and the valve of the vessel and operable during the transporting of the mold sections for determining the distance that the mold section has yet to travel and moving the vessel so as to position it directly over the final location of the mold section at the mold pouring station and for controlling during the pouring of the molten metal the operation of the valve in response to variations in the molten metal level so as to maintain a predetermined level of the molten metal during the filling operation.
