Blow moulding machine has the advantage of simplifying
This variantblow moulding machinehas the advantage of simplifying the structure of the traveller and the structure of the console by minimizing the number of parts necessary, which makes it possible to reduce the costs and total weight of the blow molding machine
The control surface is oriented downwards, and it comprises a first inclined section that is designed to move the mould base from its top position to its bottom position, an intermediate, substantially flat section, that is designed to keep the mould base in its bottom position, and a second inclined section that is designed to move the mould base 32 from its bottom position to its top position.
Note that the second inclined section serves to control the return force exerted by the springs, on the mould base to allow the mould base to rise progressively to its top position.
Advantageously, the control surface extends over an angular sector of the circular trajectory of the console , so that the trajectory of the console comprises a main angular sector during which the roller is not in contact with the control surface and a secondary angular sector during which the roller comes into contact and interacts with the control surface.
Preferably, the top position of the mould base is determined by an axial abutment (not referenced) that can be adjusted in height.
According to the embodiment shown here, the control surface comprises a substantially flat sectionthat precedes the first inclined section , according to the trajectory of the moulding unit.
One advantage of the bottle blow moulding machine according to the invention is that the adjustment of the top position of the mould base is made easier, compared with a machine according to the prior art, since the top position corresponds to a stable rest position of the mould base, determined by the axial abutment, and the mould base is held in this stable rest position by its springs.
Another advantage of the blow moulding machine according to the invention is that, during maintenance operations, the mould bases remain in the top position when the moulds are open while the roller is in an angular sector in which it is no longer in contact with the control surface: it then becomes possible to reduce the duration of these operations, since there is no longer the need always to return to position the mould bases associated with moulds that have been opened in this angular sector; furthermore.
