ABSTRACT:
The mechanism comprises a piston and cylinder assembly operable to move mould side portion supports between mould open and mould closed positions thereof. A check valve (72, 74, 76, 78, 80, 82) is mounted in a passage (66) into the cylinder to allow fluid under pressure to enter the cylinder through the passage but to prevent exit of fluid through the passage. The check valve is mounted in a chamber (66f) defined partially by the end cap (60) and partially by a cover member (67) removably mounted on the top of the end cap (60). When the cover member (67) is removed from the end cap (60), the check valve can be removed.
