Embodiment Construction

[0036] exist figure 1 with 2 The schematic structure of a device for forming preforms 1 into containers 2 is shown in .

[0037] The device for shaping the container 2 basically comprises a blow molding station 3 provided with a blow mold 4 into which the preform 1 can be inserted. The preform 1 can be an injection molded part made of polyethylene terephthalate. In order to allow the introduction of the preform 1 into the blow mold 4 and to allow the removal of the finished container 2, the blow mold 4 consists of mold halves 5, 6 and a bottom part 7 which can be lifted by a The device 8 is positioned. The preforms 1 can be held in the region of the blow molding station 3 by a transport mandrel 9 which, together with the preforms 1 , passes through several processing stations within the device. However, it is also possible to insert the preform 1 directly into the blow mold 4 , for example by means of clamps or another operating mechanism.

Abstract

The method and the device are used for blow-molding containers. To this end, following thermal conditioning inside a blow-molding tool (4), a preform is shaped into the container under the action of blowing pressure. The necessary blow-molding gas is introduced into an interior space of the preform through a connecting element. The connecting element is pressurized in the direction of a preform longitudinal axis by a contact pressure device in order to seal it relative to the preform. The blow-molding tool (4) is held by a retainer (19, 20) and is at least in some sections pneumatically tensionable relative to the carrier (19, 20). The gas used for the pneumatic tensioning of the blow-molding tool (4) relative to the carrier (19, 20) is guided to the region of the carrier (19, 20) via a base (44) that retains the connecting element (42) and can be positoned together with the connecting element (42).

Description

technical field [0001] The invention relates to a method for blow-molding containers, in which preforms are formed into containers by blowing pressure inside a blow mold after thermal conditioning, wherein the blowing gas is introduced into the In the inner space of the preform, wherein the joining element is loaded by a hold-down device in the direction of the longitudinal axis of the preform for sealing against the preform, wherein the blow mold is held by a carrier and At least in regions it is clamped pneumatically relative to the carrier. [0002] Furthermore, the invention relates to a device for blow molding containers having at least one blow molding station with a blow mold, wherein the flow path for the blowing gas for blow molding the containers passes through a joining element extension, wherein the blow molding station is provided with the engagement element which can be positioned in the direction of a longitudinal axis and which is coupled to a hold-down device...
