Embodiment Construction

[0035] figure 1is a schematic illustration of a plant for manufacturing containers of plastic material according to the prior art. The device 50 has a heating device 30 in which the plastics material pre-forms 10 are heated. In this case, the plastics material pre-forms 10 are conveyed through the heating mechanism 30 by means of a conveying mechanism 34 , such as here an endless chain, and are heated in this way by heating elements 31 . This heating mechanism 30 has attached thereto a transfer unit 36 ​​which transfers the preforms 10 to the sterilization mechanism 32 . In this case, the sterilization mechanism 32 likewise has a transfer wheel 37 on which the sterilization elements can be arranged or can even be arranged in a stationary manner. Sterilization by hydrogen peroxide gas or even by electromagnetic radiation is possible, for example, in this area. In particular, internal sterilization of the preforms is carried out in this area.

Abstract

The invention discloses a blow moulding machine with pivot shafts guided on slide bearings. The apparatus has a set of blow molding stations (8) arranged on a movable carrier (2) and including blow molds (4), a pressing mechanism and a locking mechanism (8) including a first locking element (82) and a second locking element (84). The blow mold parts (4a, 4b) are arranged on blow mold carriers (6a, 6b). At least a first bearing unit (60) is provided for movable mounting of the blow mold carriers relative to each other, and at least a second bearing unit (70) is provided for movable mounting of the first locking element (82) relative to the second locking element (84). At least one of the bearing units (60, 70) is designed in form of a slide bearing without lubricant or a bearing which is partially injected with a plastic material between bearing parts that are moved relative to each other.

Description

technical field [0001] The invention relates to a device for forming plastics material pre-forms into plastics material containers. Devices of this type are known in the prior art. In this context, for example a stretch blow molding plant is known in which plastics material pre-forms are blow molded to form plastics material containers by applying internal pressure in a plurality of blow molding stations. Each of these blow molding stations generally has two mold carrier parts on which the blow mold or blow mold parts are fastened. The heated plastics material pre-forms are blown out by means of compressed air in these blow molds and shaped to form plastics material containers. Background technique [0002] In order to remove manufactured containers and introduce new plastics material pre-forms, both mold carriers have to perform an opening movement. In this case, usually at least one mold carrier part is pivoted about an axis, or even both mold carriers are pivoted about...
