Claim:
Machine ( 10 ) for the manufacture of containers, notably bottles, made of thermoplastic, comprising at least one moulding unit ( 24 ) which comprises at least two mould holders ( 26 ) mounted such that they can move between an open position and a closed position, and a mould comprising at least two moulding elements ( 72 ) each fixed removably to an associated mould holder ( 26 ) by fixing means, the said moulding unit ( 24 ) comprising: a moulding unit ( 24 ) opening/closing device ( 46 ) comprising a control member ( 48 ) for moving the mould holders ( 26 ) between the said open and closed positions; a moulding unit ( 24 ) locking device ( 50 ) comprising a control member ( 52 ) for controlling the locking means ( 58 , 60 ) which are able to move between: a locked position in which the mould holders ( 26 ) of the moulding unit ( 24 ) are kept in a closed position by the said locking means ( 58 , 60 ), and an unlocked position in which the mould holders ( 26 ) are free to be parted from the closed position to the open position characterized in that the machine ( 10 ) comprises a control module ( 70 ) able to occupy at least: a standby state associated with one mode of operation of the machine ( 10 ), known as the production mode, in which the machine manufactures containers, and a state of use associated with another mode of operation of the machine ( 10 ), known as the intervention mode, in which at least the mould of the moulding unit ( 24 ) can be changed, and able selectively to control the moulding unit ( 24 ) locking device ( 50 ) and opening/closing device ( 46 ) according to the state occupied by the module ( 70 ), the said module ( 70 ) comprising at least: a first device ( 76 ) intended selectively to actuate the moulding unit ( 24 ) locking device ( 50 ) and mounted able to move between: a rest position occupied when the module ( 70 ) is in the standby state, and a work position occupied when the module ( 70 ) is in the state of use and in which the first device ( 76 ) is able to collaborate with the locking device ( 50 ) control member ( 52 ) under the action of means causing relative movement between the module ( 70 ) and the machine ( 10 ), a second device ( 78 ) intended selectively to actuate the moulding unit ( 24 ) opening/closing device ( 46 ) control member ( 48 ) and which is mounted such that it can move between: a rest position occupied when the module ( 70 ) is in the standby state, and a work position occupied when the module ( 70 ) is in the service state and in which the second device ( 78 ) is able to collaborate with the opening/closing device ( 46 ) control member ( 48 ) under the action of means causing relative movement between the module ( 70 ) and the machine ( 10 ), and a chassis ( 80 ) supporting said first and second devices ( 76 , 78 ) of the module ( 70 ).
