Abstract
Disclosed herein is an injection molding apparatus. That apparatus includes an axially extending bar shaped support bar and an inner mold that has a plurality of internal parts surrounding the support bar and is axially divided into a plurality of parts in which one or more corresponding parts in the inner parts have an inner circumferential surface width the same or larger than an outer circumferential surface width. The apparatus further includes an outer mold that has a plurality of axially divided external parts surrounding the inner mold and has a space between the inner circumferential surface of the outer mold and the outer circumferential surface of the inner mold.

An injection molding apparatus comprising:
- an axially extending bar shaped support bar;
- an inner mold having a plurality of inner parts surrounding the support bar in which one or more corresponding parts in the inner parts have an inner circumferential surface width the same or larger than an outer circumferential surface width;
- and
- an outer mold having a plurality of axially divided external parts surrounding the inner mold and a space formed between the inner circumferential surface of the outer mold and the outer circumferential surface of the inner mold,
- wherein the inner parts of the inner mold include four parts, and two corresponding parts of the four inner parts have the inner circumferential surface widths the same as or larger than the outer circumferential surface widths, and
- the width from the outer circumferential surface to the inner circumferential surface of the inner mold is set to be smaller than a width of the support bar.
An injection molding apparatus comprising:
