Abstract
A molding machine for molding material is provided. The machine includes a cavity to be filled with molten metal and a conduit system leading to the cavity, thus forming a system of interconnected hollow spaces. At least one pressure member is moveable in at least part of the conduit system. A centrifugal pump in fluid communication with a reservoir of molten metal is provided, the pump providing molten metal to the hollow space receiving the at least one pressure member.
Claims11
A molding machine comprising a cavity to be filled with molten metal comprised of aluminum;
- a conduit system leading to said cavity and forming a system of interconnected hollow spaces;
- at least one pressure member comprising a casting piston moveable in at least part of said hollow space system comprising a shot sleeve;
- wherein a centrifugal pump is in fluid communication with a reservoir of molten metal and the part of said hollow space system receiving the at least one pressure member, said centrifugal pump comprising a base member submerged in the reservoir of molten metal, at least two posts extending between the base member and a motor, a shaft extending between the motor and an impeller disposed in the base member;
- wherein said molten metal is introduced to said shot sleeve at a bottom side or bottom end;
- said molding machine further comprising a controller, said controller configured to control the motor associated with the centrifugal pump, said controller receiving data from at least one position, velocity, acceleration, or pressure sensor, said controller using said data to operate the centrifugal pump at a minimum of two different fill speeds during a fill of the shot sleeve;
- and wherein the conduit system of the molding machine does not include a valve below a surface of the reservoir of molten metal.
A molding machine comprising a cavity to be filled with molten metal comprised of aluminum;
- a delivery system leading to a shot sleeve which communicates with said cavity;
- at least one pressure member comprising a casting piston moveable in at least part of said shot sleeve;
- a centrifugal pump in fluid communication with a reservoir of molten metal and the delivery system, said centrifugal pump comprising a base member submerged in the reservoir of molten metal, at least two posts extending between the base member and a motor, a shaft extending between the motor and an impeller disposed in the base member;
- said molding machine further comprising a controller, said controller configured to control the motor associated with the centrifugal pump, said controller receiving data from at least one position, velocity, acceleration, or pressure sensor, said controller using said data to operate the centrifugal pump at a minimum of two different fill speeds during a fill of the shot sleeve;
- wherein the delivery system consists of an uninterrupted conduit extending between the base member and the shot sleeve and wherein the molten metal is introduced to said shot sleeve at a bottom side or bottom end.
A molding machine comprising a cavity to be filled with molten metal comprised of aluminum;
- a delivery system leading to a shot sleeve which communicates with said cavity, the delivery system including only a conduit;
- at least one pressure member comprising a casting piston moveable in at least part of said shot sleeve;
- a centrifugal pump in fluid communication with a reservoir of molten metal and the delivery system, said centrifugal pump comprising a base member submerged in the reservoir of molten metal, at least two posts extending between the base member and a motor, a shaft extending between the motor and an impeller disposed in the base member;
- said molding machine further comprising a controller, said controller configured to control the motor associated with the centrifugal pump, said controller receiving data from at least one position, velocity, acceleration, or pressure sensor, said controller using said data to operate the centrifugal pump at a minimum of two different fill speeds during a fill of the shot sleeve;
- and wherein the molten metal is introduced to said shot sleeve at a bottom side or bottom end.
