Three-Plate Die Casting Mold Having a Sprue System and Improved Sprue Separation, and Die Casting Method

A three-plate die casting mold for producing a metal die-cast part by die casting a molten metal, comprising:

• a first mold part;
• a second mold part;
• a third mold part, wherein the third mold part is disposed between the first mold part and the second mold part;
• a die cavity;
• and
• a sprue system, wherein the molten metal is feedable to the die cavity through the sprue system and wherein the sprue system has a plurality of feed channels that are disposed in the third mold part and open into the die cavity;
• wherein the plurality of feed channels in the third mold part that open into the die cavity have a respective tapering at a die cavity-side end and wherein the respective tapering locally decreases a channel cross section such that a predetermined breaking point is generated during a die casting operation which allows a defined separation of the metal die-cast part from a sprue created in the sprue system when the three-plate die casting mold is being opened.
