Abstract
A use of a feeder insert, having a volumetric center of gravity which is offset in relation to the opening axis of the passage opening of said feeder insert, in the manufacture of a casting mold having a vertical mold separation and a feeder insert which for dense feeding of the mold cavity during the casting procedure is attached to the casting mold, is described, wherein the feeder insert is positioned in a prefabricated mold part of the casting mold such that the opening axis of said feeder insert runs below the volumetric center of gravity of the latter.
Claims15
A method of manufacturing a casting mold, comprising:
- providing a feeder insert (24, 24′), having a volumetric center of gravity which is offset in relation to the opening axis (62) of the passage opening (60) of said feeder insert (24, 24′), in the manufacture of a casting mold (1) having a vertical mold separation and a feeder insert (24, 24′) which for feeding of the mold cavity (26) during the casting procedure is attached to the casting mold (1),
- wherein the feeder insert (24, 24′) is positioned in a prefabricated mold part (20, 22, 34) of the casting mold (1) such that the opening axis (62) of said feeder insert (24, 24′) runs below the volumetric center of gravity of the feeder insert.
A method for manufacturing a casting mold (1) having a vertical mold separation and a feeder insert (24, 24′) which for feeding of the mold cavity (58) during the casting procedure is attached to the casting mold (1), the method comprising the following steps:
- providing or manufacturing a first mold part (20, 22), having a vertically running first separation face (20′, 22′), for partially defining the mold cavity (26),
- providing or manufacturing a second mold part (22, 34), having a second separation face (22″, 34″) running so as to be complementary to the first separation face (20′, 22′), for partially defining the mold cavity (26), wherein the first separation face (20′, 22′) of the first mold part (20, 22) and the second separation face (22″, 34″) of the second mold part (22, 34) are provided for being joined together, configuring part of the mold cavity (26),
- providing or manufacturing a feeder insert (24, 24′) for positioning in said second mold part (22, 34), wherein the feeder insert (24, 24′) has a volumetric center of gravity which is offset in relation to the opening axis of the passage opening of said feeder insert (24, 24′),
- positioning of the feeder insert (24, 24′) in one of said mold parts (20, 22, 34), so that the opening axis (62) of the feeder insert (24, 24′) runs below the volumetric center of gravity of the feeder insert, and subsequently
- producing the casting mold (1) having the mold cavity (58), by joining together the first separation face (20′, 22′) of the first mold part (20, 22) and the second separation face (22″, 34″) of the second mold part (22, 34),
- wherein one of said mold parts (20, 22, 34) has a recess (32), and the feeder insert (24, 24′) for positioning in said mold part (20, 22, 34) of the casting mold (1) is inserted into this recess (32).
