An apparatus for shaping plastics material pre-forms into containers has a plurality of blow molding stations arranged on a movable carrier The blow molding stations have two part blow molds with a cavity inside in which the plastics material pre-forms are expanded. The blow molding stations have stressing devices which act upon the plastics material pre-forms to expand them with a flowable medium. At least one first bearing device is provided for movable mounting of the blow mold carriers with respect to each other and at least one second bearing device is provided for movable mounting of the first locking element with respect to the second locking element. At least one of these bearing devices is a slide bearing without lubricant or a bearing which is injection molded at least in part from a plastics material between bearing parts movable relative to each other.

A method for blow molding containers in blow molds of a device operated with the recovery of air from the blow molds, where operation is accomplished consecutively in a preblow stage with a low pressure and at least two further blow stages with respective higher pressures, and where subsequently, in a recovery phase with several pressure stages, air is fed from the respective blow mold, air from the blow mold is first fed into the volumes allocated to the preblow stage, with priority over a feeding at least into the volume allocated to the pressure stage following the preblow stage. Further, a blow control and a control means for the pressure in the volume, where the blow control has a program section for primarily feeding air first into the volume, and possibly for limiting the pressure in the volume to a multiple of the pressure.

An apparatus for shaping plastics material preforms into plastics material containers, having a multiplicity of shaping stations arranged on a movable carrier. The shaping stations each comprise blow moulds, inside which the plastics material preforms can be shaped into plastics material containers by application of a free-flowing medium, as well as blow mould carriers for holding these blow moulds. The blow mould carriers comprise at least two blow moulding carrier parts movable in relation to one another to open and close the blow moulds, and having at least one fastening element, via which at least one element of the shaping stations is arranged on the carrier. A clean chamber surrounds the individual shaping stations, at least in part, so that the shaping stations are movable inside this clean chamber.

A stretch-blow molding machine having at least one blow molding station, in which a split blow mold, an adjustable blow nozzle with a valve section, a stretching rod with a stretching rod drive system, and an electronic control unit are provided, the electronic control unit arranged in the blow molding station is equipped with hardware and software for selectively operating the blow molding station with a combination of a cam drive and a pneumatic drive, or a combination of an electric servo drive and a pneumatic drive, or only an electric servo drive in the stretching rod drive system. The movement of the stretching rod is initiated in the stretch-blow molding machine in the production process of a container by means of an electric servomotor with the beginning of or during the locking phase of the blow mold and before the blow nozzle is placed, and the stretching rod is already displaced to a position in which the stretching rod is either very closely approached to the preform bottom or contacts the preform bottom, or has even already pre-stretched the preform, until the blow nozzle is placed.

At least one blow-molding station is arranged on a conveying device. The blow-molding station includes a blow-mold that forms a cavity into which plastics material pre-forms are expanded by a gaseous medium, supplied by a stressing device. A clean room at least partially surrounds the blow-molding station. A stretching unit stretches the plastics material pre-forms along their longitudinal direction with a stretch bar that is insertable into the plastics material pre-forms. The stretching unit includes a drive device for moving the stretch bar. The blow molding station includes a receiving space with at least one wall for receiving the stretch bar. In operation, the drive device is positioned outside the receiving space at least part of the time. A gaseous medium at a pressure higher than ambient pressure in a non-sterile environment of the receiving space is supplied to the receiving space.

An apparatus for shaping plastic preforms into plastic containers includes a transport device on which a plurality of blow molding stations are arranged. Each of these blow molding stations comprises a blow mold inside which a plastic preform can be shaped into a plastic container. The apparatus includes a clean chamber inside which the plastic preforms can be transported. The region of the transport device in which the blow molding stations are arranged is arranged in the clean chamber and at least one further region of the transport device is arranged outside the clean chamber.

The invention relates to an apparatus (1) for the stretch blow molding of plastics material pre-forms to form plastics material containers with a carrying device (2) for carrying a blow mold (3) comprising at least two shell parts (4, 5) and a base part (6) and with a base part clamping device (10) comprising a base part receiving means (11; 111) and holding devices (12, 13 and 14, 15; 114, 115 respectively) for holding the base part receiving means (11; 111), in which the base part receiving means (11; 111) is capable of being clamped to the holding devices (12, 13 and 14, 15; 114, 115 respectively) by way of a fastening with positive locking (18; 118), in which the fastening with positive locking (18; 118) has positive locking areas (22) produced from ceramic material.
摘要:
Apparatus for transforming plastic preforms into containers includes a blow moulding station on a movable carrier. The station includes a carrier for holding a blow mould, and the carrier includes a first part and a second part, pivotable with respect to the first part relative to a predefined first pivot axis. The station includes a lock mechanism for locking the first part with respect to the second part. Lock mechanism includes a first element arranged on the first part and a second element arranged on the second part. At least the first element is movable with respect to the carrier relative to a second predefined axis. Pivoting movement of the first part and movement of the first element are coupled to one another by a coupling device such that the second axis moves with respect to the carrier in a direction perpendicular to the second axis.
