ABSTRACT:
The apparatus includes a first female mold member defining a shaped mold cavity for receiving a plastisol layer or skin. A second mold member is pivotally disposed on the female mold member between an open and closed position. In the open position, the second mold member receives and holds thereon a portion of the plastisol skin extending from the mold cavity. An insert is positioned in the mold cavity by a third mold member such as a mold lid on which the insert is releasably retained. After the insert is positioned in the mold cavity, the second mold member is pivoted toward the mold lid to fold the skin portion thereon over and against an edge of the insert. The skin is folded adjacent the pivot axis of the second mold member. Foam can then be introduced and cured between the skin and insert.
