An arrangement is described. The arrangement comprises a closing unit for a blow-molding machine having a first and second mold carrier and a blow-molding tool arranged on the closing unit having two tool halves. A mold lower part of each tool half is movable in relation to the mold upper part of each tool half in a second movement direction different from the first movement direction back and forth between an open state and a closed state by means of at least one first or at least one second actuator and the blow-molding tool in the closed state of the two tool halves delimits a mold cavity having undercuts when the two mold lower parts are also in the closed state. The actuators, for example hydraulic cylinders, may arranged on the closing unit and make them able to be coupled to the mold lower part.

The invention relates to a mold for molding a hollow body from a preform, the mold defining a molding cavity having the shape of the a hollow body to be molded. The mold including a first part and a second part movable relative to each other between an opened configuration, wherein the preform can be loaded inside the molding cavity, and a closed configuration, wherein the molding cavity is formed. The mold further including a locking element arranged to maintain the mold in its closed configuration in a locked position of the mold. The locking element having at least a sleeve portion arranged around a portion of the first and second parts in the closed configuration such that the sleeve portion surrounds the portion of the first and second parts and prevents the mold from moving towards its open configuration in the locked position of the mold.

A method for forming containers from preforms. The method includes loading successive preforms into successive molds at a mold loading station, each mold having a mold cavity in the shape of the containers to be produced. The containers being formed in a forming station by injecting a gaseous or liquid fluid into the preform in order to expand the preform and acquires the shape of the container defined by the mold cavity. The steps performed at the mold loading station and the forming station are distinct from each other, and a transferring step occurs at a transferring station arranged between the mold loading station and the forming station where successive molds containing the preforms are transferred from the mold loading station to the forming station.

A device for blow molding containers, provided with a supporting frame for at least one station for blow molding preforms in order to obtain containers, the blow molding station includes two lateral bodies and a bottom which are adapted to provide by blow molding at least one container, at least one of the two lateral bodies being movable on command by virtue of elements for cyclic opening and closing, with respect to the supporting frame, about an articulation axis which is substantially parallel to the axis of the container.

A machine and method for forming containers from preforms. The machine includes a mold loading station for loading successive preforms into successive molds, each mold forming a mold cavity having the shape of the container to be produced. The machine also including a forming station for forming the containers by injecting a gaseous or liquid fluid into the preform contained in each mold in order to expand the preform such that each preform acquires the shape of the container defined by the mold cavity. In the machine, the mold loading station and the forming station are distinct from each other, and the machine further includes a transferring station arranged between the mold loading station and the forming station for transferring the successive molds containing the preforms from the mold loading station to the forming station.

A device for blow molding containers, which is provided with a supporting frame for at least one station for blow molding preforms in order to obtain containers, the blow molding station including two lateral bodies and a bottom which are adapted to provide by blow molding at least one container, at least one of the two lateral bodies being movable on command by way of means for cyclic opening and closing, with respect to the supporting frame, about an articulation axis that is substantially parallel to the axis of the at least one container, means being provided for kinematic connection between the at least one movable lateral body and the bottom and being adapted to produce cyclically the movement of the bottom along a movement direction substantially parallel to the; the cyclic opening and closing means include an actuation body which is supported by a first link rod which can be moved with respect to the supporting frame about a pivoting axis which is substantially parallel to the articulation axis (101), the first link rod being kinematically connected to the at least one movable lateral body and being associated rotatably with a contoured body that defines a cam-like profile that can be engaged by at least one engagement element supported by the bottom.

Moving servo motors of molds in synchronization with the operations of platens which enables fine patterns or shapes to be formed even on a large molded article. A mold clamping device forms patterns or the like on a molded article by detecting a mold position of a second platen among first, second, third platens with digital mold opening/closing position detector, and driving servo motors for molds of the molds in synchronization with a digital mold opening/closing position signal from the digital mold opening/closing position detector.

A device including a drive mechanism and a mold carrier that is divided into a first part (3a) and a second part (3b) which are configured to hold a respective section (2a, 2b) of a mold for forming a hollow container from a parison through the introduction of a gaseous or liquid pressurized medium under pressure into the parison. The first part (3a) is connected to the drive mechanism (6) by a first part connection region (7a) and is rotatable by the drive mechanism about an axis of rotation (A) such that the first part and the second part are transitionable between an open position and a closed position relative to each other. The first part connection region passes through a protective wall (8) that is arranged between and separates the mold carrier from the drive mechanism and thereby protects the drive mechanism against contamination on the mold carrier side.
