ABSTRACT:
Injection moulding apparatus consists of a rotary carrier (11) which transports a number of mould sets (14,15) in turn through an injection station (46), cooling stations (35) and a mould opening station (27). The injection body (62) is upwardly arranged, and there is a positioning device (71-74) for adjusting the position of the injection head (60) when in an injection position and in a withdrawn position, and a further positioning device (65,66) for moving the injection head (60) relative to the injection body. The clamping device (47) at the injection station and the cooling device (36,37) at the cooling station can also be used as heat transfer devices. The sprue formed between the mould cavity (17) and the inlet (18) of the mould set can be severed while the mould set is closed. During transfer between the injection station and the opening station, tools (14) and (15) of the mould set are held in a closed condition by connectors (16) and retaining elements (21,22) which are part of the mould set. There are openings in the carrier that provide access for devices to operate on the mould set.
