Abstract

A peripherally encapsulated product, such as an oven door outer shell, is molded in accordance with this invention by placing a piece of glass between mold clamping portions of relatively movable closed bodies when the latter are in an open position. Preferably both bodies are heated and thermosetting polymeric material (SMC or BMC) is placed upon selected areas of one of the mold bodies within and about an area corresponding to an annular mold cavity and outboard of a peripheral edge of a piece of glass. The glass is clamped between mold clamping portions of the mold bodies which are then progressively closed creating compression forces which extrude the thermosetting polymeric material into the annular cavity and into complete encapsulation of the continuous peripheral edge of the piece of glass. The handle can be integrally molded during the molding process.

Claims

1. A molded door comprising a single piece of hot molded integral thermosetting polymeric material forming a generally polygonal frame member defined by a front wall of a substantially annular configuration disposed substantially transverse to a peripheral wall substantially bordering said front wall, said thermosetting polymeric material being one of sheet molding compound (SMC) and bulk molding compound (BMC), a piece of tempered glass substantially closing an opening defined by an innermost heat and pressure extruded edge portion of said front wall, said glass piece having a peripheral edge, and said glass piece peripheral edge being encapsulated by said front wall innermost heat and pressure extruded edge portion.

2. The molded door as defined in claim 1 wherein said frame member includes a plurality of integrally molded bosses for receipt of fasteners.

3. The molded door as defined in claim 1 wherein said frame member includes a plurality of integrally molded reinforcing ribs.

4. The molded door as defined in claim 1 wherein said frame member includes a plurality of integrally molded bosses for receipt of fasteners, and said bosses are located adjacent corners of said frame member.

5. The molded door as defined in claim 1 wherein said frame member includes a plurality of integrally molded reinforcing ribs, and said reinforcing ribs are located adjacent corners of said frame member.

6. The molded door as defined in claim 1 including a second generally polygonal frame member having an opening substantially covered by a second piece of tempered glass, and means for securing said frame members to each other in generally peripherally aligned relationship.

7. The molded door as defined in claim 1 including a second generally polygonal frame member having an opening substantially covered by a second piece of tempered glass, said second frame member being constructed from metal, and means for securing said frame members to each other in generally peripherally aligned relationship.

8. The molded door as defined in claim 1 including a second generally polygonal frame member having an opening substantially covered by a second piece of tempered glass, means for securing said frame members to each other in generally peripherally aligned relationship, and said peripheral wall being in substantially outboard overlapping relationship to a peripherally outermost edge portion of said second frame member.

9. The molded door as defined in claim 6 wherein said first-mentioned frame member includes a plurality of integrally molded bosses in part defining said securing means.

10. The molded door as defined in claim 6 wherein said first-mentioned frame member includes a plurality of integrally molded reinforcing ribs.

11. The molded door as defined in claim 6 wherein said first-mentioned frame member includes a plurality of integrally molded bosses in part defining said securing means, and said bosses are located adjacent corners of said first-mentioned frame member.

12. The molded door as defined in claim 6 wherein said first-mentioned frame member includes a plurality of integrally molded reinforcing ribs, and said reinforcing ribs are located adjacent corners of said first-mentioned frame member.
