ABSTRACT:
A casting tool for the production of castings, particularly cores for sand castings, pressure die-castings, and gravity die-castings is provided. The casting tool has a casting tool unit with a casting mold half having a mold recess the contour of which partly defines the shape of the casting, and an ejecting assembly disposed on that side of the casting mold half which faces away from the mold recess. The ejecting assembly has an ejecting rod which extends through an access bore into the mold recess in the casting mold half. An entrainer unit is attached to the ejecting assembly. The entrainer unit and a contact surface provided on the casting tool unit jointly define the maximum distance of the casting tool unit from the ejecting assembly.
