Final Design of the Cope and Drag Patterns

Cope Pattern

Drag Pattern

• The photos above show the patterns for making the cope and the drag sections of the mold.

• The final mold design uses a horizontal parting line with six couplers in a rectangular pattern.
• Molten metal feeds down a center sprue, and spreads through runners into the gates with the risers.
• There are six risers positioned on the gates feeding into the six couplers. Each coupler is fed molten metal from two sides.
