1. A three-plate die casting mold for producing at least one metal die-cast part by die casting a metal melt, the die casting mold comprising:
a first, a second, and a third mold part, with the third mold part being arranged between the first and the second mold parts;
at least one die cavity;
a sprue system, through which the metal melt is fed to the at least one die cavity; and
at least one spring-pretensioned pressing element arranged in the third mold part, wherein:
when the die casting mold is being opened, a sprue created in the sprue system is torn off from the at least one metal die-cast part created in the at least one die cavity and the at least one metal die-cast part is removable by way of a first mold parting plane between the second mold part and the third mold part, and the sprue is removable by way of a second mold parting plane between the first mold part and the third mold part, and
when the die casting mold is being opened in the second mold parting plane, the at least one spring-pretensioned pressing element in the third mold part presses the sprue against the first mold part, whereby the sprue is retained and tears off from the at least one metal die-cast part in a defined manner.
