Abstract:
There is provided an injection die characterized in that the injection die is separated into at least two pieces, that a cavity for frame is formed between the separated dies, that the cavity for frame is provided with an additional cavity via a coupling hole, and that the coupling hole communicating with the additional cavity is provided at a confluence point of a resin in melted condition of the cavity for frame, at around a gate, at around a cavity for a fixing component, or at around a cavity for frame of which thickness is deep.
Abstract:
In an injection molding die, there is defined a cavity for a frame or a cavity for the frame and an auxiliary cavity communicating with the cavity for the frame, and into the cavity for the frame or the auxiliary cavity, there is injected a melted resin from a runner through a gate, and a section of the gate has a width of 1 to 5 mm in the direction of a thickness of a plate glass and a width of 10 mm or more in the direction parallel with a side of the plate glass but smaller than a side length of the plate glass. When this die is practically used, a load that would be applied to a peripheral portion of the plate glass during injection molding is reduced, so that when the frame is integrally molded to the plate glass by injection molding, undesired breakage of the plate glass is suppressed.
Abstract:
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.

Abstract:
A decorative molding that is to be fixed to a frame of a framed window glass plate for a vehicle is provided. The decorative molding is configured such that when the frame is formed around a peripheral portion of a glass plate by injecting a molten resin, the decorative molding is simultaneously fixed to the frame. The body of the decorative molding is made of a metal. A cationically electrodeposited coating film is formed on a surface of the body of the decorative molding and a resinous coating film is formed on the cationically electrodeposited coating film.
Abstract:
A composite multi-layer substrate comprising a flat plate-like core member formed of a material having an excellent electric conductivity, an excellent heat conductivity, and a high rigidity, a front resin layer and a rear resin layer covering at least the front and rear surfaces of the core member, and a bottomless hole formed in the core member through the front and rear sides of the core member, wherein an electronic component is installed in the bottomless hole, whereby since the strength of the composite multi-layer substrate can be assured by the rigidity of the core member, conventional prior art glass cloth can be eliminated, deterioration in the electric characteristics caused by ion migration can be avoided and will result in reduced production cost.
