ABSTRACT:
The two halves of the core box in a core blowing machine are mounted on a carrier which may be turned 180.degree. between a blowing position in which sand is blown into the closed core box and a discharging position in which the core box halves are separated in the direction of the axis of rotation and the molded core is ejected. A transfer receptacle moves into the discharging zone between the separated core box halves to receive the ejected core and to withdraw it from the discharging zone while the core box is again being closed and simultaneously turned with the carrier into the blowing position.
