Abstract
Disclosed herein are systems and methods for production and use of a casting mold for casting components. The casting mold comprises at least one casting mold frame made of metal and/or of an alloy, and also one or more ceramic casting mold inserts introduced into the at least one casting mold frame. The casting mold insert(s) have the negative contour or part of the negative contour of a component to be produced or of the combination of a component to be produced with one or more casting cores.
Claims14
A casting mold for casting components, the casting mold comprising;
- at least one casting mold frame made of a metal or of an alloy;
- and
- multiple ceramic casting mold inserts which are configured to be introduced into the at least one casting mold frame and which comprise a negative contour or a part of the negative contour of a component to be produced, or of a combination of a component to be produced with at least one casting core;
- wherein the multiple ceramic casting mold inserts are introduced into the at least one casting mold frame, wherein the multiple casting mold inserts comprise the negative contour or the part of the negative contour of the component to be produced or of the combination of a component to be produced with the at least one casting core, wherein the ceramic casting mold inserts each include a material, and wherein a first material of a particular one of the ceramic casting mold inserts has a material characteristic property that includes at least one of a heat conductivity different from a second material of at least a second particular one of the ceramic casting mold inserts, a coefficient of thermal expansion different from the second material of the second particular one of the ceramic casting mold inserts, or a heat conductivity and a coefficient of thermal expansion different from the second material of the second particular one of the ceramic casting mold inserts.
A casting mold for casting components, the casting mold comprising:
- a casting mold frame made of at least one of a metal or an alloy;
- and
- a set of ceramic casting mold inserts configured to be introduced into the casting mold frame, wherein each of the ceramic casting mold inserts comprises:
- a negative contour, or a part of the negative contour, of a component or a combination of a component to be produced with a casting core;
- wherein each of the ceramic casting mold inserts is introduced into the casting mold frame, wherein each of the ceramic casting mold inserts comprise the negative contour or the part of the negative contour of the component to be produced with the casting core, wherein a particular ceramic mold insert of the set of the ceramic casting mold inserts includes a first material, wherein a second particular ceramic mold insert of the set of ceramic casting mold inserts includes a second material different from the first material, and wherein the first material has a material characteristic property that includes at least one of a heat conductivity different from the second material, a coefficient of thermal expansion different from the second material, or a heat conductivity and a coefficient of thermal expansion different from the second material, and wherein either the first material or the second material has a heat conductivity of between 1.5 and 50 W/mK, inclusive, and wherein the material is at least one of:
- SiN, SiAlON, aluminum titanate, or a mixture thereof.
