Apparatus and method for coupling and uncoupling media couplings on the base mould

Abstract

Apparatus () for reshaping plastic preforms () into plastic containers () has a blow moulding device () which has at least two side parts () and a base mould () which form a hollow space inside which the plastic preforms () are reshaped into the plastic containers (), wherein the apparatus has a changing device () which is suitable and intended either to remove the complete blow moulding device () or only parts () of the blow moulding device () from the blow mould supports () thereof and/or to arrange them on the blow mould supports (), wherein the base mould () is arranged on a base mounting (), and in a changing mode, through a lifting movement (H) and in particular a lifting and/or lowering of the base mounting (), the base mould () can be connected to the base mounting () or can be disconnected from the base mounting (), and between the base mounting () and the base mould () at least one first disconnectable media connection () is provided, by means of which a flowable medium can be supplied to the base mould () and/or by means of which the flowable medium can be discharged from the base mould (). According to the invention the media connection () between the base mounting () and the base mould () can also be made and/or can be broken by the lifting and/or lowering of the base mounting ().
