Apparatus and method for producing multiple cores

摘要

A core box assembly for molding cores includes a first core box (3) and a second core box (40) disposed above the first core box. Each of the core boxes has a cavity (47) . A passage (55) for delivering core material to the cavities in the core boxes extends through the second core box and into the first core box. A method for producing cores using such apparatus includes the steps of placing the second core box above the first core box and injecting core material into the core boxes. <IMAGE>
