Process for producing a cast wheel and casting mould

摘要

Process and casting mold for producing a cast wheel. A core, which remains in the cast wheel and has a circumferential rim, is inserted into a casting mold having at least one lower mold part and an upper mold part moved relative to one another to close casting mold. Core is positioned by at least one positioning element in a predetermined position in casting mold, so that an end region of positioning element is fixed with a force fit or frictional fit in circumferential rim of the core. A free end region of positioning element, which protrudes from circumferential rim of the core, is placed on a contact surface, which is preferably arranged substantially horizontally during operation, of lower mold part during positioning of core in casting mold. Core is positioned in the predetermined position under the action of the force of gravity.

主权项

1. A process for producing a cast wheel, comprising:
inserting a core, which has an annular shape and remains in an area of an outer rim of the cast wheel, but not in an area of a spoke of the cast wheel, into a coquille casting mold having at least a lower coquille mold part and an upper coquille mold part, which are moved relative to one another to close the coquille casting mold; positioning the core is by at least one positioning element in a predetermined position in the coquille casting mold, wherein an end region of the positioning element is fixed with a force fit or frictional fit in the annular-shaped core; placing a free end region of the positioning element, which protrudes from the annular-shaped core, on a contact surface of the lower coquille mold part of the coquille casting mold during positioning of the core in the coquille casting mold, so the core is positioned in the predetermined position against the force of gravity.
