| 摘要 |
The present invention relates to a cavity for a mould-cavity system for the production of hollow mouldings, where the cavity (1) has an element (2) which is in essence hollow and cylindrical, where a cooling channel has been provided at the outer side of the hollow cylindrical element (2). To provide a cavity which is easy to produce and which can increase the effectiveness of cooling of the cavity, the invention proposes provision of the cooling channel with a plurality of cooling-channel sections (3) extending substantially axially, and with at least one cooling-channel-connector section (4), where the cooling-channel-connector section (4) connects two of the cooling-channel sections (3) extending substantially axially.
