Patent number: 10112235Abstract: An arrangement for use in the production of a separable casting mold, preferably of a vertically separable casting mold is disclosed. The arrangement can include (i) a mold plate and/or a mold pattern, (ii) a feeder system having a feeder element and having a feeder insert, wherein feeder element and feeder insert delimit a feeder cavity for receiving liquid metal. The arrangement also includes one or more tipping prevention elements which are designed to counteract tipping of the feeder system out of the opening axis about the first end of the feeder element when, in the event of the feeder system being acted on with a force acting parallel to the opening axis and in the direction of the first end, the side wall deforms and the spacing between the first and second ends is reduced, wherein the one or more tipping prevention element(s) are/is spaced apart from the opening axis.Type: GrantFiled: August 7, 2015Date of Patent: October 30, 2018Assignees: CHEMEX GMBH, HUETTENES-ALBERTUS CHEMISCHE WERKE GMBHInventors: Nicolas Egeler, Michael Biemel, Heiko Schirmer
