Pivot mold assembly defining internal pivot member

A mold assembly for forming an inner structure positioned between a pair of spaced molded walls defined by a retention member for retaining said inner structure between said spaced, molded walls, which comprises:

• a pair of cooperating, openable and closable mold members adapted to define mold spaces for forming the molded walls, the improvement comprising:
• a pair of pivotable members positioned between the spaces for forming the molded walls, said pivotable members defining free ends which abut together in a first pivoting position and which are spaced from each other in a second pivoting position, said free ends cooperatively defining between them a mold cavity for forming said inner structure, positioned between the molded walls, said mold cavity being defined by cavity portions defined in the abutting free ends of said pivotable members, and additional flow passageway means, of smaller transverse dimension than said mold cavity, positioned in the abutting, free ends of said pivotable members and communicating between said mold cavity and one side of said pivotable member, said flow passageway communicating, in the first pivoting position, with a mold space for forming said molded walls to provide access of mold material into said mold cavity whereby said pivotable members are adapted to occupy their first pivoting position while the mold assembly is closed to receive and shape molding compound into the molded inner structure, and said pivotable members are adapted to be pivoted into their second pivoting position upon opening of the molded assembly and removal of the molded part by action of the molded part, to facilitate removal of the molded structure.
