Abstract
The invention pertains to the field of foundry and more particularly relates to a model (12) for lost model foundry in the shape of a turbine engine blade having a base (15) and a body (14) separated by a platform (20) substantially perpendicular to a main axis of the blade. The blade body (14) has a lower surface (17) an upper surface (16) a leading edge (18) and a trailing edge (19). The model (12) further includes a heat expansion rod (21) adjacent to the trailing edge (19) and a refractory core (23) imbedded in the model (12) but having both on the lower surface (17) side and on the upper surface (16) side a lacquered surface (31) flush between the trailing edge (19) and the heat expansion rod (21). A web (24) extends between the platform (20) and said heat expansion rod (21) and has a free edge (25) therebetween. The invention also relates to a method for making a shell mold from said model (12) and to a foundry method using said shell mold.
