摘要： A mold comprising a first mold element and a second mold element releasingly engagable between an open position and a closed position to define a mold cavity in the closed position and a first part line between the first mold element and second mold element. The first mold element comprises a first mold portion and a second mold portion configured to be reversible separable with respect to one another to define a second part line therebetween disposed interiorly with respect to a periphery of the first part line. At least one vent is disposed in the second part line. In one embodiment, the at least one vent comprises a passageway configured to permit mold material in the mold cavity to enter but not to exit the passageway to cause at least partial curing of the mold material in the passageway.

摘要： An assembly for molding a composite article including a foam core and a layer is disclosed. The assembly includes a mold. The mold has an inner surface and at least partially defines a cavity, one or more gas discharge ports, and one or more retaining elements. Each of the one or more gas discharge ports has a passageway opening in fluid communication with the cavity of the mold the mold. The assembly further includes one or more sealing elements moveably engaged with the mold. Each of the one or more sealing elements includes a head and is shaped to engage the retaining element on the mold in a vented position. Further, each of the one or more sealing elements corresponds with each of the one or more gas discharge ports.
