METHOD OF MOLDING PRODUCT HAVING HOLLOW INTERIOR REGION

摘要

A method of molding a product includes receiving into a cavity of a mold a core having a plurality of parts that are unconnected and that together form the core, situating a first part of a plurality of parts adjacent a second part of the plurality parts, receiving a material in an uncured state into a space between the mold and the core, forming with the first part a first portion of the interior region, forming with the second part a second portion of the interior region that is contiguous the first portion, removing the first part from within the first portion of the interior region, through a hole, and subsequent to the removing of the first part, removing the second part from within the second portion of the interior region, through a hole.

1. A method of molding a product having a hollow interior region and having a plurality of holes in communication between an interior region and an exterior of the product, the method comprising:
receiving into a cavity of a mold a core having a first part and a second part that are unconnected and that together form the core; situating the first part adjacent the second part; inserting a material in an uncured state into a space between the mold and the core, at least partially curing the material; forming with the first part, a first portion of the interior region; forming with the second part, a second portion of the interior region, the second portion being contiguous with the first portion; removing the first part from within the first portion of the interior region, through a first hole of the plurality of holes; and removing the second part from within the second portion of the interior region, through at least one of the first hole and a second hole of the plurality of holes.
