Abstract
Official abstract text for this publication.
Disclosed herein is an injection molding die used for producing a frame-mounted plate glass by injection molding. The die is characterized in that an auxiliary cavity is provided at a position to exposed a surface of a plate glass and communicated with a cavity for a frame through a communication opening, the cavity for the frame being provided at position facing a vehicle inside surface of the plate glass. When the die is practically used for injection molding, a load applied to a peripheral portion of the plate glass during the injection molding is reduced, so that when the frame is molded onto the plate glass by injection molding, undesired breakage of the plate glass is suppressed.
First claim
Opening claim text (preview).
The invention claimed is: 1. An injection molding die used for producing, by injection molding, a frame-mounted plate glass that comprises a plate glass and a plastic frame integrally molded to a peripheral portion of the plate glass, the injection molding die comprising: a lower die that is set to face a vehicle inside surface of the plate glass; an upper die that is set on the lower die in a manner to face a vehicle outside surface of the plate glass; and a series of a cavit…
