Hinge Plate
Final Design of the Cope and Drag Patterns

Cope Pattern for the Hinge Plate

Drag Pattern for the Hinge Plate

• The photos above show the patterns for making the cope and the drag molds for the hinge plate. The mold design uses a horizontal parting line along the main plate.

• The mold is a “2-on” design producing two castings for each pour. Molten metal feeds down a single center sprue and feeds through two gates into each plate.

• There are four square risers positioned over each plate and shown in red in the cope photo.

• The side walls face down in the drag mold. Three cores produce the center cavity and the two inner flange walls for each casting. The yellow cores are positioned to show their placement in the drag mold
