Problems solved by technology

However, when inserting the riser insert into the groove, which can for example be done by hand or by means of an insertion device, the riser insert may not be positioned exactly in the groove due to inaccuracies
In particular, this can lead to irregularities in the produced castings and to costly reworking
In particular, imprecise insertion of the riser insert into the groove can render the castings produced unusable

Embodiment Construction

[0058] exist figure 1 In , a riser insert 2 according to the invention is shown in a cross-sectional view according to a first embodiment. The riser insert 2 has a riser body 4 comprising a riser cavity 6 for receiving liquid metal. The riser insert 2 has a riser opening 10 at the first end 8 on the riser body 4, by means of which a riser opening can be established with the molding 26 ( image 3 ) The connection of the molding cavity 30 in. The riser body 4 is closed at the opposite second end 12 and has a side wall 14 extending between the first end 8 and the second end 12 . A filter element 16 is arranged in the feeder cavity 6 , by means of which filter element the material flowing through the feeder insert 2 is cleaned. In the present embodiment, even though the feeder body is constituted by a plurality of single parts such as the feeder element 18 and the cover 20, the feeder main body 4 is constituted in one piece. In the present case, one-piece is to be understood a...

Abstract

The invention relates to a method for producing a moulded part (26), having a feeder insert arranged therein and having an inlet for liquid metal, for a separable casting mould for metal casting, comprising the steps of: producing or providing a moulded part (26) equipped with a closed feeder insert (2) from a compressed moulding material (28), the closed feeder insert (2) being arranged stationary in the compressed moulding material (28) of the moulded part (26) and having a feeder opening (10) connected to regions of the mould cavity (30) to be formed, and opening the closed feeder insert (2) such that an inlet (32) for liquid metal is formed.

Description

technical field [0001] The invention relates to a method for producing a molded part with a riser insert arranged thereon for a separable mold of a metal casting, the riser insert having a A gate for liquid metal. Furthermore, the invention relates to a molded part for a separable casting mold and a casting mold consisting of at least two molded parts. Furthermore, the invention relates to the use of a riser insert for use in a method for producing molded parts and a closed riser insert. The invention is defined by the claims and disclosed in detail in the ensuing specification. Background technique [0002] Riser inserts are used in great number and variety when casting metal in molds. The riser insert, also known as the riser system, is at least partially surrounded by the molding material used to produce the casting mould, for example molding sand. The riser insert is held in a predetermined position within the mold by means of the molding material surrounding the ris...
