Collapsible core and a casting mold half equipped therewith

Abstract

A collapsible core is provided for attachment to a mold half of a casting mold, particularly a diecasting mold. The collapsible core can take the form of a removable collapsible core which can be detachably mounted on the mold half on the mold cavity side. A collapsible core can have a core cylinder body of at least two first core sections in the form of cylinder segments and at least two second core sections in the form of cylinder segments arranged alternating with the first sections over the circumferential direction. The first and the second core sections are retained moveably relative to one another. The relative movement here between the first and the second core sections consists of an axial relative movement component between the first and the second core sections and a radial collapsing movement of the first and/or the second core section.
