Abstract:
1. A molding device for manufacturing thermoplastic containers by blow-molding or stretch-blow-molding heated parisons, said molding device comprising at least one blow-molding mold of the hinged mold type with at least two mold halves which can be separated from one another by rotation about a common axle of articulation under the action of actuating means; wherein the actuating means are designed in such a way that the two mold halves have respective angles of opening on each side of the parting plane of said mold which are not equal; wherein the actuating means comprise two link rods having first ends rotationally connected by links respectively to said two mold halves and second ends rotationally connected at a common axle and control means capable of moving said common axle in a path running approximately parallel to the parting plane; wherein said two link rods have different lengths and in that the path of the common axle is external to the parting plane, the mold half driven by the shorter link rod having an angle of opening, with respect to the parting plane, which is larger than that of the other mold half.
