Abstract

The invention relates to a tool for manufacturing a foundry core for producing a cooling circuit for a turbine engine blade, including a mould (40) for injecting a paste, which comprises cavities (42, 44) for a first portion and at least one other portion of the core, and means (50, 54) for supporting and/or fitting end portions of at least one ceramic rod which connects the above mentioned portions of the core and which passes through the cavity for the first portion of the core , characterized in that it includes in the cavity for the first portion of the core, a means (58) for supporting a medial portion of the rod.
