1. A tool for fixing a connecting head on an electrode casted in a mold, comprising:
a connecting head support extending along a longitudinal axis;
a mold base, supported by the support, the mold base defining an axial orifice for passage of the connecting head;
an end-piece for mounting the support on a movement member for moving the tool in the mold; and
a mechanism for longitudinal immobilization of the connecting head on the support;
wherein the mechanism for longitudinal immobilization is longitudinally adjustable relative to the support in order to immobilize the connecting head relative to the support in at least two different longitudinal positions along the longitudinal axis.
 
12. An installation for producing metal parts, comprising:
a refining hearth assembly, comprising at least one mold for forming an electrode by casting,
a tool according to claim 1, movably mounted in the mold, the tool bearing a connecting head;
the hearth assembly comprising a movement member for moving the tool in the mold, the mounting end-piece of the support of the tool being mounted on the movement member.
 
14. A method for producing metal parts, comprising the following steps:
loading a connecting head in a tool according to claim 1;
adjusting the longitudinal position of the connecting head relative to the support in a selected longitudinal position;
immobilizing the connecting head in the selected longitudinal position, using the longitudinal immobilizing mechanism;
inserting the mold base into a mold for forming an electrode by casting, at least part of the connecting head protruding from, being flush with or being set back from the mold base;
pouring molten metal into the mold on said part of the connecting head;
moving the tool using a movement member of the mold to form the electrode.
