An apparatus for forming plastic preforms into plastic containers with at least one forming station which forms the plastic preforms into the plastic containers by the action of a flowable medium, wherein the forming station has a blow mould which forms a cavity, within which the plastic preforms are formed into the plastic containers. The blow mould has a base part which has an inner contour which forms a base of the containers, wherein the base part has at least one channel for conducting a temperature control medium for temperature control of the base part. A course of the channel is adapted to a course of the inner contour and/or the channel has, on its inner surface facing the temperature control medium, structures and/or cross-sectional changes which influence the flow of the temperature control medium through the channel.
A forming apparatus for forming plastic preforms into plastic containers, said forming apparatus having at least one forming station for forming the plastic preforms into the plastic containers by being acted upon by a flowable medium, wherein the forming station has a blow mould having a cavity within which the plastic preforms are formed into the plastic containers, wherein the blow mould has a base part which has an inner contour which forms a base of the containers, and wherein the base part has at least one channel for conducting a temperature control medium for temperature control of the base part, wherein a course of the channel is adapted to a course of the inner contour and the channel has, on its inner surface facing the temperature control medium, structures and cross-sectional changes which influence the flow of the temperature control medium through the channel, wherein the structures are formed as protrusions or webs extending into the channel and wherein recesses are provided adjacent to the webs, wherein bores are provided configured to establish or deflect a coolant flow.
A base part of a blow mould for forming plastic preforms into plastic containers, which has an inner contour which forms a base of the containers, wherein this base part has at least one channel for conducting a temperature control medium for temperature control of the base part, wherein
A method for forming plastic preforms into plastic containers, wherein the plastic preforms are formed into the plastic containers by action of a flowable medium in a forming station, wherein the forming station has a blow mould which forms a cavity within which the plastic preforms are formed into the plastic containers, and this blow mould has a base part which has an inner contour and which forms a base of the containers, and wherein this base part has at least one channel through which a temperature control medium for temperature control of the base part is passed,
