The invention relates to a molding device for blowing thermoplastic recipients of various heights, said device comprising a mould provided with two mould halves and a mould bottom which are mutually mobile. Each mould half comprises a mould carrier, a chill carrier and a chill, said two chills and the mould bottom comprising mould impressions, which together define a molding cavity. The inventive device also comprises means for compensating the blowing pressure, said means being provided between a mould carrier and the associated chill carrier. For recipients with the maximum height, the chill carriers and chills are the same height. For lower recipients, the chills are lower than the chill carriers and radially reinforcing means are provided on the internal faces of the carriers in the parts thereof which do not co-operate with the chills.

The invention claimed is: 1. A molding device for manufacturing containers, particularly bottles, made of thermoplastic, such as PET, by blow-molding or stretch-blow-molding and which are liable to have different heights, said molding device comprising at least one mold which comprises two mold halves able to move relative to one another and a mold base able to move relative to the two mold halves in axial translation, each mold half comprising a mold holder, a shell holder fixed to the mold holder and a shell supported by the shell holder, the two shells and the mold base comprising respective molding cavity portions which, when the mold is in the closed position, together define a molding cavity, means for compensating for the blowing pressure being provided between a mold holder and the respective shell holder, comprising the following combination of features: to manufacture containers of the tallest height (maximum height), the shell holders and shells have substantially identical respective heights, to manufacture containers of heights shorter than said maximum height, the shells have a height shorter than that of the respective shell holders and reinforcing means are provided on the respective internal faces of the shell holders in those parts thereof that are not cooperating with the respective shells, said reinforcing means being able radially to reinforce those parts of the shell holders that are not cooperating with the respective shells when the pressure-compensating means are active. 2. The molding device as claimed in claim 1, wherein the shells are sported by the respective shell holders in such a way that their respective upper edges are substantially aligned with one another, in that, to manufacture containers of heights shorter than said maximum height, those parts of the shell holders which are not cooperating with the respective shells are the lower parts of the shell holders, and in that the reinforcing means are located in said lower parts of the shell holders. 3. The molding device as claimed in claim 2, wherein the reinforcing means comprise, on each shell holder, at least two strips projecting from the respective longitudinal edges of the shell holder substantially as a continuation of the shape of the shell holder and covering a distance along the perimeter that is such that when the molding is in the closed position, the frontal surfaces of the strips belonging to the respective shell holders bear against one another just as do the shells. 4. The molding device as claimed in claim 3, wherein the strips are located along the lower edge or in close proximity to the lower edge of the respective shell holders. 5. The molding device as claimed in claim 4, wherein the shell holders have respective ribs which project radially inwards and extend around the entire perimeter of the shell holders, along the lower edge or in close proximity to the lower edge thereof, even facing the strips. 6. The molding device as claimed in claim 2, wherein the reinforcing means comprise two semi-tubular portions which are situated under the shells, which have a height substantially equal to the difference in respective heights of the shell holders and shells and which have substantially the same external perimeter as the shells so that the respective longitudinal frontal surfaces of the two portions bear against one another when the mold is in the closed position. 7. The molding device as claimed in claim 6, wherein the semi-tubular portions have, passing through their wall, longitudinal bores capable of accepting components for fastening them, particularly by screwing, to the respective shells.
