Abstract

A method for producing a window glass for a vehicle provided with an ornamental braid comprises steps of setting an ornamental braid on a lower mold of an injection molding machine, fixing an ornamental braid connection member on the lower mold, setting a glass plate on the lower mold, closing an upper mold, thereby locking the molds, and injecting molten resin into a cavity formed between the lower mold and the upper mold, thereby integrally molding a resin frame, the ornamental braid and the ornamental braid connection member along a periphery of the glass plate.

Claims

1. A method for producing a window glass for a vehicle provided with an ornamental braid, comprising the steps of:

setting an ornamental braid comprising a channel-shaped cross section on a lower mold of an injection molding machine with an open end of the ornamental braid facing upwords,

setting an ornamental braid connection member of rectangular parallelopiped shape on the lower mold, with one end portion of the connection member fitted in an end portion of the ornamental braid,

setting a glass plate on the lower mold,

closing an upper mold, thereby locking the molds, and

injecting molten resin into a cavity formed between the lower mold and the upper mold, thereby molding a resin frame integrally with, the ornamental braid and the ornamental braid connection member, with the connection member projecting from the end portion of the ornamental braid.

2. A method for producing a window glass for a vehicle provided with an ornamental braid of claim 1, further comprising a step of clamping the ornamental braid with the ornamental braid connection member and the lower mold, thereby fixing the ornamental braid on the lower mold.

3. A method for producing a window glass for a vehicle provided with an ornamental braid of claim 1, further comprising a step of clamping the ornamental braid with a plurality of projections formed on the ornamental braid connection member and the lower mold, thereby fixing the ornamental braid on the lower mold.

4. A method for producing a window glass for a vehicle provided with an ornamental braid of claim 1, further comprising a step of inserting a pin projecting from the lower mold into a hole formed in the ornamental braid connection member, thereby fixing the ornamental braid connection member on the lower mold.

5. A method for producing a window glass for a vehicle provided with an ornamental braid of claim 1, further comprising a step of engaging a plurality of projections formed on the ornamental braid connection member with a plurality of hollows formed on the lower mold, thereby fixing the ornamental braid connection member on the lower mold.

6. A method for producing a window glass for a vehicle provided with an ornamental braid of claim 1, further comprising a step of engaging a plurality of hollows formed on the ornamental braid connection member with a plurality of projections formed on the lower mold, thereby fixing the ornamental braid connection member on the lower mold.

7. A method for producing a window glass for a vehicle provided with an ornamental braid of claim 1, wherein the ornamental braid connection member is provided with a hollow for engaging the resin frame.
