Cores formed with connecting cavities for receiving connecting sand |

Cores have a plurality of cavities defined by adjacent vertical side surfaces of two adjacent cores. These cavities are arranged horizontally and spaced apart along the surfaces. Providing such a plurality of cavities in the surfaces produces an increased total surface area extending in the direction where the cores mate or separate.
