Patent ID: 8323019

Claim:
A blow mould apparatus for moulding plastic preforms into plastic containers with a first mould carrier element and a second mould carrier element which is swivelable about a connecting axis in relation to the first mould carrier element, wherein the mould carrier elements cooperate such that in a closed state of the blow mould apparatus they form in their interior a cavity in which the plastic preforms can be expanded into plastic containers, and with a locking device which locks the first mould carrier element in relation to the second mould carrier element in order to hold the blow mould apparatus at least temporarily in the closed state, wherein the locking device has at least one locking element which is arranged on one of the mould carrier elements and is mobile and cooperates with the other mould carrier element to lock the mould carrier elements and wherein the locking device comprises a mobile actuation element, the movement of which is coupled at least temporarily with a movement of the locking element, the actuation element or locking element being mobile between at least two prespecified positions, wherein the locking device comprises a guide device which is arranged on the blow mould apparatus and cooperates with the locking element or actuation element such that the locking element or actuation element is forced into one of the two positions, wherein the guide device has a curve device with a curved outer surface, the movement of which is coupled with a movement of the actuation element, and wherein the curve device has at least two curve elements, the relative position of which can be modified.
