Abstract
Improvements to machines for manufacturing hollow bodies by extrusion and blowing. It comprises at least one extruder 1, 2, which provides a tube of plastic material, at least one blowing mandrel 3, 4 and a mould 5 integral with a transversely moveable carriage 6, the mould 5 being formed by two halves 7, 8 which can be moved by hydraulic actuating means, and the mould 5 and the carriage 6 being able to slide in guide columns 13, 14, 15, and is characterised in that the means of actuating the two halves 7, 8 of the mould 5 comprise a first hydraulic cylinder 9 of smaller cross section and larger travel associated with a rod mechanism 11, 12 the cylinder of which shifts the two halves 7, 8 of the mould, and a second hydraulic cylinder 10 of larger cross section and smaller travel, which applies the pressure necessary for moulding the hollow bodies. The columns 13 for guiding the mould 5 and the columns 14, 15 for guiding the carriage 6 are all mounted on the same frame 16. The power of the hydraulic unit is reduced, and the assembly of the columns is facilitated. Applies to the manufacture of plastic bottles.
