Moulding equipment

Moulding equipment comprising a mould and a dispensing container for dispensing molten mouldable material into the mould, the mould and container having cooperable male and female connectors to connect them together for allowing transfer of pressurized fluid from the container into the mould, the female connector having a slot extending radially from its outer periphery to a central orifice and with the length of the slot lying in a circumferential direction of the orifice, the slot pivotally carrying a locking member about an axis parallel to the axis of the central orifice, the locking member being pivotally movable through the slot into and out of a locking position in which the locking member has a locking cam projecting radially into the orifice;

• and the male connector formed with a circumferential recess and being insertable into the orifice with the recess aligned with the cam for movement of the cam into the recess and, during movement of the locking member into the locking position, surfaces of the cam and the circumferential recess oppose each other axially of the connectors and move relatively one across the other while normally offering sufficiently low resistance to movement of the locking member so as to allow for manual operation, and during transfer of pressurized fluid, said surfaces are urged together axially of the connectors by a force applied by internal fluid pressure to provide or increase resistance to relative movement of the surfaces, thereby to increase resistance to movement of the locking member out of the locking position.
