Abstract
A device for die casting a metal component included a die casting mold which has a cavity that forms the component. The cavity is connected to a source for a metal melt by at least one temperature controlled supply channel. The metal melt is introduced into the cavity via at least one casting valve. The supply channel forms an annular channel, in which metal melt can be circulated via a conveying apparatus.
Claims19
A device for die casting a metal component, comprising:
- a die casting mold having a cavity that forms the component;
- a supply channel connecting the cavity with a source of metal melt, wherein the supply channel is temperature controlled and wherein the supply channel is formed, in at least one portion, from pipe pieces and connecting pieces that connect the pipe pieces;
- and
- a casting valve by which the metal melt is introduced into the cavity, wherein the supply channel forms an annular channel in which the metal melt is circulatable via a conveying apparatus and wherein the annular channel encircles the cavity.

- a supply channel connecting the cavity with a source of metal melt, wherein the supply channel is temperature controlled;
- a casting valve by which the metal melt is introduced into the cavity, wherein the supply channel forms an annular channel in which the metal melt is circulatable via a conveying apparatus and wherein the annular channel encircles the cavity;
- wherein:
- the casting valve has a valve body movable transversely with respect to a longitudinal axis of the supply channel,
- in a closed position of the valve body, the valve body closes an outlet opening connecting the supply channel to the cavity, and
- in an open position of the valve body, the valve body at least partially opens up the outlet opening;
- and
- a regulating device for the valve body, the regulating device being thermally insulated from the supply channel.
