Apparatus for molding a trim panel assembly having a narrow transition radius
View Patent ↗In at least certain embodiments, the present invention relates to a trim panel and an apparatus and method of making the same. In at least one embodiment, the trim panel comprises a first portion and a second portion with a transition portion extending therebetween with the first portion and the second portion having curved portions having radii of less than 5 mm.
1. An apparatus for molding a part, said apparatus comprising:
a first mold half having a first molding surface, the first molding surface having a projecting member projecting away from the first mold half;
a second mold half having a second molding surface, the mold halves being capable of relative movement between a first position and a second position;
the first and second molding surfaces helping to define a mold cavity when the mold halves are in the second position; and
a support member that is capable of supporting the projecting member of the first mold half when the mold halves are in the second position, the support member being able to allow fluid to pass through the support member.
2. The apparatus of claim 1 wherein the support member has at least one channel that allows fluid to pass through the support member.
3. The apparatus of claim 2 wherein the support member includes a plurality of channels that allow fluid to pass through the support member.
4. The apparatus of claim 2 wherein the at least one channel has a first portion extending in a first, generally horizontal, direction, and a second portion extending in a second, generally vertical, direction.
5. The apparatus of claim 4 wherein the support member is integral with the second mold half.
6. The apparatus of claim 4 wherein the support member is capable of moving relative to the first mold half and the second mold half between a first support member position, and a second support member position and the support member is able to support the projecting member of the first mold half when the support member is in the second support member position.
7. The apparatus of claim 2 wherein
the second mold half has a positioning member for aligning a coverstock on the first mold half, the positioning member being capable of moving relative to the first mold half and the second mold half between a first positioning member position and a second positioning member position; and
the positioning member being able to align the coverstock on the first mold half when the positioning member is in the second positioning member position.
8. The apparatus of claim 1 wherein the support member is capable of supporting the projecting member against a force perpendicular to the direction of projection.
9. The apparatus of claim 8 wherein the force is between 50 psi and 6000 psi.
10. The apparatus of claim 6 wherein the support member is adjacent the projecting member when the support member is in the second support member position.
11. The apparatus of claim 10 wherein the support member contacts the projecting member when the support member is in the second support member position.
12. The apparatus of claim 5 wherein the apparatus is suitable for molding a substrate partially covered by coverstock, wherein
the mold cavity further comprises a first region, a second region and a transition region;
the first region being covered by the coverstock;
the second region being uncovered by the coverstock;
the projecting member being disposed between the first and second regions within the transition region;
the projecting member having a projecting member surface;
the first molding surface and the second molding surface helping to define the mold cavity in the first region when the mold halves are in the second position;
the support member having a third molding surface;
the first molding surface, second molding surface, and the third molding surface helping to define the mold cavity in the second region when the mold halves and the support member are in the respective second positions; and
the projecting member surface, second molding surface and third molding surface helping to define the mold cavity in the transition region when the mold halves and the support and the support member are in the respective second positions.
13. The apparatus of claim 12 wherein when the mold halves are in the second position, the first region of the mold cavity, the transition region of the mold cavity, the at least one channel of the support member, and the second region of the mold cavity are in fluid communication.
14. The apparatus of claim 1 wherein the projecting member has a base portion having a radius of between 0.1 mm and 5 mm.
