Embodiment Construction

[0054] exist figure 1 The riser insert 2 according to the invention is shown in its initial setting. The riser insert 2 has a feed element 4 and a die body 6 . Preferably, the feed element and mold body 6 are formed as substantially rotationally symmetrical shaped parts. The axis of rotation of the riser insert 2 running in the longitudinal direction of the riser (longitudinal riser axis) is indicated by the dotted line 8 . The mold body 6 has an outer contour which widens conically upwards in the lower section from the underside 12 of the mold body. In the middle section 14 , which extends over half the entire height of the mold body 6 , the mold body 6 has only one outer contour which is also slightly conically widened. In the upper section of the molding body, the molding body again tapers conically and terminates in a horizontally running upper side 16 . The inner contour of the die body 6 , which delimits the feeder cavity, has an inner wall 18 that tapers slightly co...

Abstract

A feeder insert for use for the casting of metals into casting molds, having a mold body (6) said a supply element (4) which delimit the feeder cavity (10) for receiving liquid metal, wherein the supply element (4) has a passage opening (26) for the liquid metal, and wherein the mold body (6) is movable in a feeder longitudinal direction relative to at least one part of the supply element (4), characterized in that the supply element (4) has a deformation region (22) which is designed to turn in at least in sections in at least a first phase of a relative movement of the mold body (6) in the feeder longitudinal direction and in the direction of the supply element (4).

Description

technical field [0001] The invention relates to a riser insert for use when casting metal into a mold, said riser insert having a mold body delimiting a riser cavity for receiving liquid metal and a supply element, wherein the supply element has a A through opening for the liquid metal, and wherein the mold body is movable relative to at least one part of the feed element in the longitudinal direction of the riser. Furthermore, the invention also relates to a method for arranging such a riser insert in a casting mould. Background technique [0002] Riser inserts known in advance, also referred to simply as risers, are used in particular in manufacturing processes for casting metal into molds. The riser insert usually forms a cavity surrounded by the molding material of the casting mould. The cavity provided for receiving the metal in the casting mold has a through-opening to the feeder cavity in which the partial quantity of liquid metal filled into the casting mold rises ...
