Injection-moulding machine with an index shaft having a channel for a fluid

An injection-moulding machine, having a first platen (8.1), which is designed for carrying a first mould half (7.1) of an injection mould (7), a second platen (8.2), which is designed for carrying a second mould half (7.2) of the injection mould (7) in such a way that in a closed state of the injection mould (7) the first mould half (7.1) and the second mould half (7.2) delimit at least one cavity (9) of the injection mould (7), and having an index shaft (13), which is mounted rotatably and axially adjustably on the injection-moulding machine (1) outside the injection mould (7), is rotationally driven by means of a motor (M) of the injection-moulding machine (1) arranged outside the injection mould (7) and has an end portion (13.1) which protrudes into the injection mould (7) in the installed position of the injection mould (7) in the injection-moulding machine (1), is designed for fastening on the index shaft (13) an index plate (14) to be arranged within the injection mould (7) and has at least one continuous channel (15) extending directly between the end portion and an opposing end portion of the index shaft adjacent to the motor, wherein said at least one continuous channel is configured to feed a fluid to the index plate (14) or to remove a fluid from the index plate (14), wherein by means of the index shaft (13), driven by the motor (M), the index plate (14) is automatically adjustable between a first plate position of the index plate (14) and at least one second plate position of the index plate (14), and wherein the motor (M) has a hollow motor shaft (17), through which the fluid is passed.
