Abstract
For transporting a train (15) of flaskless molds using a simply designed system along a storing, teeming and cooling run or part of a conveyor in a foundry so that the castings are made highly true to size, the forces needed for speeding up and slowing down the mold train (15) are caused to take effect at a desired level on the mold train (15) and, together with the forces acting oppositely to the thermal expansion of the molds (7) within the mold train (15), the forces are transmitted to the full length of the mold train only by the molds (7) themselves.
Claims18
A process for the transport of a mold train of flaskless molds on movable transporting structures along storing, teeming and cooling stations in a foundry and having at least one straight conveyor run on which said transporting structures are supported, new teeming molds joining, one after the other, a back end of the mold train and filled molds being taken therefrom at the same rate from a front end of the train, comprising the steps of:
- (a) lining up said molds in said mold train with their end faces resting against each other, said molds having upright end and side faces normal to the conveyor plane;
- (b) transporting said mold train by speeding up and braking forces adjusted as necessary and as needed, said speeding up force taking effect at the back end of said mold train and said braking force taking effect at the front end thereof;
- and
- (c) transmitting said forces together with any forces acting against thermal expansion within said mold train along the full length of the mold train only by said molds, from one mold to the mold next thereto.
Apparatus for casting including flaskless molds and a conveyor for transporting a mold train of said flaskless molds along storing, teeming and cooling stations and having at least one straight conveyor run, new teeming molds joining, one after the other, a back end of the mold train and filled molds being taken therefrom at the same rate from a front end of the train, wherein said conveyor stretches from a mold-producing station to a shake-out station and includes turning supports turning about fixed axes, and said conveyor including transport structures for supporting one or more molds having a length in the transport direction smaller than the length of the mold or molds placed thereon, said mold or molds stretching out to the back and front of each such transport structure, and said transport structures placed at one of the front or back ends of one run of the mold train are geared with a driving unit and at the other end with a braking unit by means of at least one adjustable torque limiting slip clutch.
