Abstract

A mold insert assembly includes a base section having a base side removably attachable to a base plate of a mold and a first interface surface having a notched portion thereon. A first section includes a first interface side with a first interconnecting tab sized to engage the notched portion of the base section when the first interface side abuts the first interface surface, the first section further including an adjoining side having an interconnecting notch. A second section includes a second interface side having a second interconnecting tab, where the second interconnecting tab is sized to engage the interconnecting notch of the first section when the second interface side abuts the adjoining side, and where the base section, the first section, and the second section when assembled form a contoured insert configured to create a contoured cavity in a part formed within the mold.

First claim

What is claimed is:

1. A mold insert assembly comprising:
a base section having a base side removably attachable to a base plate of a mold, the base section further comprising a first interface surface having a notched portion thereon;
a first section having a first interface side with a first interconnecting tab thereon, wherein the first interconnecting tab is sized to engage the notched portion of the base section when the first interface side abuts the first interface surface, the first section further comprising an adjoining side having an interconnecting notch;
a second section having a second interface side, the second interface side having a second interconnecting tab, wherein the second interconnecting tab is sized to engage the interconnecting notch of the first section when the second interface side abuts the adjoining side; and
wherein the base section, the first section, and the second section when assembled form a contoured insert configured to create a contoured cavity in a part formed within the mold.

2. The mold insert assembly of claim 1 , wherein the adjoining side of the first section is a first adjoining side, wherein the interconnecting notch is a first interconnecting notch, and wherein the first section further comprises a second adjoining side having a second interconnecting notch, the mold insert assembly further comprising:
a third section having a third interface side, the third interface side having a third interconnecting tab, wherein the third interconnecting tab is sized to engage the second interconnecting notch of the first section when the third interface side abuts the second adjoining side, wherein the base section, the first section, the second section, and the third section when assembled form the contoured insert.

3. The mold insert assembly of claim 2 , further comprising a cable attachable from the base section to the first section.

4. The mold insert assembly of claim 3 , wherein the cable is a first cable, wherein the mold insert assembly further comprises a second cable attachable from the second section, through an aperture in the first section, to the third section.

5. The mold insert assembly of claim 1 , wherein, after the part is formed within the mold, the contoured insert is separable by successively removing the base section, the first section, and then the second section from the part.

6. The mold insert assembly of claim 1 , wherein the contoured insert comprises a base cross-section having a perimeter, and wherein the base section, the first section, and the second section each extend outside the perimeter along a height of the contoured insert.

7. The mold insert assembly of claim 6 , wherein the perimeter of the base cross-section establishes an opening perimeter of the contoured cavity in the part.

8. The mold insert assembly of claim 6 , wherein the base section, the first section, and the second section each form a portion of the base cross-section.

9. The mold insert assembly of claim 8 , wherein the base side of the base section comprises a base protrusion sized to engage a depression in the base plate of the mold, and wherein the first section comprises a first protrusion sized to engage the depression in the base plate.

10. The mold insert assembly of claim 9 , wherein the second section comprises a second protrusion sized to engage the depression in the base plate.

11. A method of assembling a mold insert assembly comprising:
removably attaching a base side of a base section to a base plate of a mold, the base section further comprising a first interface surface having a notched portion thereon,
engaging a first interconnecting tab on a first interface side of a first section with the notched portion of the base section, wherein the first interface side of the first section abuts the first interface surface of the base section, the first section further comprising an adjoining side having an interconnecting notch;
engaging a second interconnecting tab on a second interface side of a second section with the interconnecting notch of the first section, wherein the second interface side of the second section abuts the adjoining side of the first section; and
wherein the base section, the first section, and the second section when assembled form a contoured insert configured to create a contoured cavity in a part formed within the mold.

12. The method of claim 11 , wherein the adjoining side of the first section is a first adjoining side, wherein the interconnecting notch is a first interconnecting notch, and wherein the first section further comprises a second adjoining side having a second interconnecting notch, the method further comprising:
engaging a third interconnecting tab on a third interface side of a third section with the second interconnecting notch, wherein the third interface side of the third section abuts the second adjoining side of the first section, wherein the base section, the first section, the second section, and the third section when assembled form the contoured insert.

13. The method of claim 12 , further comprising:
attaching a cable from the base section to the first section.

14. The method of claim 13 , wherein the cable is a first cable, the method further comprising:
attaching a second cable from the second section, through an aperture in the first section, to the third section.

15. The method of claim 11 , wherein the base side of the base section comprises a base protrusion, wherein removably attaching the base side of the base section to the base plate further comprises engaging the base protrusion within a depression in the base plate, wherein the first section comprises a first protrusion, and wherein engaging the first interconnecting tab on the first interface side of the first section with the notched portion of the base section further comprises engaging the first protrusion of the first section within the depression in the base plate.

16. The method of claim 15 , wherein the second section comprises a second protrusion, and wherein
engaging the second interconnecting tab on the second interface side of the second section with the interconnecting notch of the first section further comprises engaging the second protrusion within the depression in the base plate.

17. A method of forming a part within a mold, the method comprising:
removably attaching a base side of a base section to a base plate of a mold, the base section further comprising a first interface surface having a notched portion thereon;
engaging a first interconnecting tab on a first interface side of a first section with the notched portion of the base section, wherein the first interface side of the first section abuts the first interface surface of the base section, the first section further comprising an adjoining side having an interconnecting notch;
engaging a second interconnecting tab on a second interface side of a second section with the interconnecting notch of the first section, wherein the second interface side of the second section abuts the adjoining side of the first section, wherein the base section, the first section, and the second section when assembled form a contoured insert configured to create a contoured cavity in a part formed within the mold; and
forming the part within the mold around the contoured insert.

18. The method of claim 17 , further comprising:
after forming the part within the mold, removing the base section from the contoured cavity;
after removing the base section, removing the first section from the contoured cavity; and
after removing t
