Apparatus for making vehicle panel assembly
First Claim
1. A mold assembly for forming a polymeric structure on one surface of a sheet-like panel having opposite surfaces, comprising:
- a pair of cooperating mold sections movable between open and closed positions, said mold sections adapted to receive, engage and hold the sheet-like panel therebetween when said mold sections are in said closed position, each mold section having a facing surface which faces the other mold section;
a mold cavity defined in a first portion of said facing surface of a first of said mold sections, said first portion of said facing surface of said first mold section having a support area adjacent said mold cavity, said support area adapted to support and seal against the one surface of the sheet-like panel such that said mold cavity opens to the one surface of the panel when the panel is held between said mold sections in said closed position;
a heat insulative pad on the second of said mold sections, said pad being urged against the surface of the sheet-like panel which is opposite the one surface at a position opposite said mold cavity to hold the one surface of the panel against said support area and overlying said mold cavity when said mold sections are in said closed position; and
a resilient member located between said heat insulative pad and said second mold section, said resilient member urging said heat insulative pad against the opposite surface of the panel when said mold sections are in closed position,whereby when a polymeric molding material is introduced in said mold cavity, a polymeric structure defined by said mold cavity will be formed on the one surface of the panel.

Abstract
A mold assembly for forming a panel assembly having a gasket on one surface for use as a flush-mounted panel or window in vehicles, buildings, or other structures includes a mold cavity defined in a facing surface of one mold section and a pressure pad on the second mold section, the pressure pad being urged against the surface of a sheet-like panel at a position opposite the mold cavity with the panel being held against a support surface adjacent the mold cavity when the mold sections are closed. Preferably, the pressure pad is a heat insulative pad which is urged against the panel surface by a resilient member preferably formed from urethane. The support surface and mold cavity are preferably raised above and offset from adjacent portions of the first mold section, and the size of the raised area of the support surface and mold cavity preferably corresponds in size to the area of the pressure pad.
