Abstract

Improvements in expandable molds for the manufacture of plaster pieces, comprising at least one lateral surface provided with reliefs, characterized in that they comprise at least two walls assembled by means of at least two incompressible deformable elements arranged respectively between two parallel lateral edges of the walls so as to ensure the tightness between these walls so as to ensure the tightness between these walls, each of the elements adopting towards the interior of the mold during molding under the effect of pressure, a profile determined in advance that corresponds to that it must be conferred on a surface of the molded part and that it contracts out of contact with the molded part during the demoulding after the release of pressure, at the same time separating from each other said walls between which it is arranged while still ensuring the tightness between its edges, a base surface on which the aforementioned rest walls and the compressible elements, and an arranged pouring hole between the walls.
