- the invention relates to a device for forming plastic preforms to plastic containers.
- plastic preforms are heated in an oven and blown in this heated state to plastic bottles.
- the heated plastic preforms are introduced into blow molds and subjected to compressed air within these blow molds. If different containers are to be blown, the blow molds must be exchanged.
- the parts of the blow mold in particular their side parts and bottom parts, are released from the carriers and replaced by other blow molds.
- blow molding machines have recently become known from the prior art. Such blow molding machines can be used, for example, to produce already sterilized plastic containers, which are needed in particular in the filling of sensitive drinks. It is necessary to sterilize the respective machine at predetermined time intervals.
- Applicator's current internal state of the art blow molding is carried out in a specially isolated area by an operator.
- a device that actuates the mold carrier allows the operator to remove the blow molds from the mold carrier via a window to the sterile area of the blower wheel.
- the blow molds are stored separately in the bottom mold and two side parts or mold shells in a special blow molding magazine, which is housed in a specially insulated area. After manually changing the blow molds, the sterile area of the blower wheel is sterilized with the molds used, for example by means of H2O2.
