Method of molding product having hollow interior region
View Patent ↗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.
2. The method according to claim 1 , wherein
the removing of the first part and the removing of the second part being initiated at two different times.
3. The method according to claim 1 , wherein,
the removing of the first part and the removing of the second part including moving the first and second parts in two different directions away from the product.
4. The method according to claim 2 , further comprising
attaching two different structures to the first and second parts so as to move the first and second parts in the two different directions away from the product.
5. The method according to claim 1 , wherein
the two different structures are first and second lugs that attach to the first and second parts, respectively.
6. The method according to claim 5 , wherein
the first and second lugs are disposed in first and second holes of the plurality of holes, respectively.
7. The method according to claim 1 , wherein
the removing of the first part includes removing the first through a first hole from among the plurality of holes.
8. The method according to claim 7 , wherein
the removing of the second part includes removing the second through a second hole from among the plurality of holes.
9. The method according to claim 8 , wherein
the removing the first part through the first hole includes changing a size of the first hole.
10. The method according to claim 9 , wherein
the removing the second part through the second hole includes changing a size of the second hole.
11. The method according to claim 1 , wherein
the first and second parts have substantially the same shape.
