Abstract
A method and an apparatus 10 for selectively venting air 98 from the internal cavity 94 of a mold 90. Particularly, the apparatus 90 includes a body 12 having a selectively movable member 30 whose position within the body 12 determines whether the air 98 is vented from the mold 98. After the air 98 is vented,. The member 30 returns to a normal position in which communication between the internal cavity 94 of the mold 90 and the ambient environment 100 is foreclosed.
Claims11
1) An apparatus comprising a generally hollow body having a first outlet portion and a second threaded inlet portion;
- an element which is movably disposed within said generally hollow body;
- and a generally hollow top having a threaded portion which is adapted to be selectively coupled to said second threaded inlet portion, said top further having a outwardly protruding spring which engages said movable element when said threaded portion of said top is selectively coupled to said threaded portion of said second inlet portion and wherein said top includes an orifice which communicates with said generally hollow body.
5) An apparatus for selectively and cleanly removing air from a mold, said apparatus comprising a generally cylindrical and hollow body having a longitudinal axis of symmetry and opposed orifices which are positioned along said longitudinal axis of symmetry, said body having a threaded portion which circumscribes a first of said pair of orifices;
- a ball which movably resides within said generally cylindrical and hollow body and upon said longitudinal axis of symmetry;
- and a top portion having threads which are adapted to be selectively and removably coupled to said threaded portion of said body, said top further having an outwardly protruding spring which is positioned within said generally hollow body along said longitudinal axis of symmetry and in contact with said ball when said top portion is attached to said body, wherein a second of said pair of orifices is adapted to selectively receive said air from said mold and communicate said received air to said ball which causes said ball to move against said spring and allow said received air to pass through said generally hollow body and to be outputted from said second of said pair of orifices and wherein said spring, in the absence of said received air, pushes said ball against said first of said pair of orifices, thereby closing said first of said pair of orifices.
10) A method for selectively releasing air from a mold, said method comprising the steps of receiving said air;
- providing an outlet from said mold;
- causing said received air to freely travel a certain and substantial distance within said apparatus before impacting any portion of said apparatus;
- and thereafter causing said received air to enter said outlet.
