Embodiment Construction

[0040] by means of Figure 1 to Figure 4 The schematic diagram in illustrates the function of the apparatus for blow molding beverage containers or plastic bottles and the method for changing individual blow moulds.

[0041] figure 1 with figure 2 The schematic perspective view in shows a base 10 of a device for blow molding plastic containers, which is only partially shown. image 3 with Figure 4 A half shell of a blow mold is shown. The half-shells are openable laterally and the bottom shape 14 of the base 10 can be pressed towards the lower front side of the half-shells. at the same time, figure 1The illustration in shows a situation where a fluid connection 12 is bonded to a base 10 to supply cooling fluid to the base 10, figure 2 The fluid connection 12 is shown detached. The bottom shape 14 includes integrated fluid tubes (not shown) for tempering the bottom shape 14 during blow molding or stretch blow molding of the plastic container. The coolant fluid tubes ...

Abstract

The invention relates to a device and a method for blow moulding plastic containers. A device for blow molding plastic containers includes an openable and closable blow mold for the conversion of tempered plastic preforms, whereby an inner blow pressure is applied to the plastic containers. The blow mold contains at least two shell like blow mold pieces that are arranged interchangeably at a blow mold carrier and that each contains cooling fluid pipes as conducts for a cooling fluid extending therein to temper the blow mold during and / or after blow molding of the plastic containers. The cooling fluid pipes in the blow mold are connected to a central cooling fluid supply. A coupling module that is associated with the blow mold carrier is arranged between the central cooling fluid supply and the cooling fluid pipes extending in the blow mold pieces. The coupling module and the blow mold carrier are associated spatially and / or structurally.

Description

technical field [0001] The invention relates to a device for blow molding plastic containers, which device is characterized in that the device comprises an openable and closable blow mold for plastic preforms by applying internal blow pressure to the The tempered plastic preforms are thus transformed into plastic containers. The invention also relates to a method for blow molding plastic containers. Background technique [0002] During the production of plastic containers for drinking liquids, high temperatures are used to cause the preforms to be reshaped in blow molds or stretch blow molding units. For blow molding, suitable blow molds made of several parts are used. Typically, such blow molds are made of two parts that can pivot relative to each other and a base that slides against closed blow mold pieces. The temperature change during blow molding or stretch blow molding is accomplished by cooling fluid that is directed through fluid pipes in the blow molded part. Th...
