Summary: | 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. |
