Abstract

A molding assembly having a top mold member and a base mold member. The top mold member can include a first top mold portion and a second top mold portion that shift between a top mold open configuration and a top mold closed configuration by rotating about a top mold hinge axis. The molding assembly can shift between a molding assembly open configuration and a molding assembly closed configuration by rotating at least the top mold member about a molding assembly hinge axis.

First claim

What is claimed is:

1. A molding assembly, comprising:
a base mold member;
a top mold member, the top mold member comprising a first top mold portion and a second top mold portion, wherein the first top mold portion and the second top mold portion are rotatable, about a top mold hinge axis, between a top mold open configuration and a top mold closed configuration; and
a top plate disposed adjacent the first top mold portion and the second top mold portion and opposite the base mold member, the top plate being in a fixed orientation relative to the top mold hinge axis,
wherein at least the top mold member is rotatable, about a molding assembly hinge axis, between a molding assembly open configuration and a molding assembly closed configuration, wherein as the top mold member rotates about the molding assembly hinge axis from the first top mold portion and the second top mold portion of the top mold member shift away the base mold member, wherein, when in the molding assembly closed configuration, the base mold member and the top mold member in the top mold closed configuration, are cooperatively adapted to form at least a portion of a mold surface for an article, and wherein the top mold hinge axis and the molding assembly hinge axis are positioned within 15 centimeters of one another.

2. The molding assembly according to claim 1 , wherein the molding assembly hinge axis is positioned within 15 centimeters of an end of the base mold member.

3. The molding assembly according to claim 1 , further comprising a molding assembly hinge mechanism, wherein the molding assembly hinge mechanism is adapted to rotate at least the top mold member about the molding assembly hinge axis, and wherein at least part of the molding assembly hinge mechanism is coupled to at least part of the base mold member.

4. The molding assembly according to claim 1 , further comprising an article securing mechanism, wherein the article securing mechanism and the base mold member are positioned on opposite sides of the top mold member.

5. The molding assembly according to claim 1 , wherein, when the top mold member and the base mold member are in the molding assembly open configuration, at least a portion of the top mold member, the top plate, or both are positioned on an opposite side of the molding assembly axis than the base mold member.

6. The molding assembly according to claim 1 , wherein the top mold member comprises a top mold member outer surface and a top mold member inner surface, and the base mold member comprises a base mold member outer surface and a base mold member inner surface, wherein the top mold member inner surface comprises a top mold molding portion and a top mold non-molding portion, and the base mold inner surface comprises a base mold molding portion and a base mold non-molding portion, and wherein the top mold non- molding portion of the top mold inner surface and the base mold non-molding portion of the base mold inner surface comprise complementary contacting regions.

7. The molding assembly according to claim 6 , wherein the top mold non-molding portion of the top mold inner surface and the base mold non-molding portion of the base mold inner surface comprise complementary curved contacting regions.

8. The molding assembly according to claim 1 , wherein the at least a portion of the mold surface for the article comprises at least a portion of an outsole or midsole for an article of footwear.

9. A molding assembly, comprising:
a base mold member;
a top mold member, the top mold member comprising a first top mold portion and a second top mold portion, wherein the first top mold portion and the second top mold portion are rotatable, about a top mold hinge axis, between a top mold open configuration and a top mold closed configuration;
a top plate, the top plate comprising one or more top mold member securing mechanisms adapted to secure the top mold member in the top mold closed configuration, the top plate being in a fixed orientation relative to the top mold hinge axis,
wherein at least the top mold member is rotatable, about a molding assembly hinge axis, between a molding assembly open configuration and a molding assembly closed configuration, wherein as the top mold member rotates about the molding assembly hinge axis from the first top mold portion and the second top mold portion of the top mold member shift away from the base mold member, wherein, when in the molding assembly closed configuration, the base mold member and the top mold member in the top mold closed configuration, are cooperatively adapted to form at least a portion of a mold surface for an article, and wherein, when in the molding assembly closed configuration, the top mold member is positioned between the top plate and the base mold member.

10. The molding assembly according to claim 9 , wherein at least a portion of the one or more top mold member securing mechanisms extends into a recess of the top mold member to secure the top mold member in the top mold closed configuration.

11. The molding assembly according to claim 9 , further comprising an article securing mechanism, wherein the article securing mechanism and the base mold member are positioned on opposite sides of the top mold member.

12. The molding assembly according to claim 11 , wherein an adjustment plate of the article securing mechanism is vertically shiftable to shift towards and away from the top mold member.

13. The molding assembly according to claim 12 , wherein the article securing mechanism further comprises an article engaging component, wherein at least part of the article engaging component is removably coupled to the adjustment plate and adapted to secure the article to the article securing mechanism.

14. The molding assembly according to claim 9 , further comprising a molding assembly hinge mechanism, wherein the molding assembly hinge mechanism is adapted to rotate at least the top mold member about the molding assembly hinge axis, and wherein at least part of the molding assembly hinge mechanism is coupled to at least part of the base mold member.

15. A method for utilizing a molding assembly, the method comprising:
securing an article to a top plate using one or more article securing mechanisms;
rotating one or both of a first top mold portion and a second top mold portion of a top mold member about a top mold hinge axis, the top mold hinge axis being in a fixed orientation relative to the top plate, from a top mold open configuration to a top mold closed configuration; and
rotating the top mold member in the top mold closed configuration, the top plate, and the article, about a molding assembly hinge axis, toward a base mold member into a molding assembly closed configuration, wherein the top mold hinge axis and the molding assembly hinge axis are positioned within 15 centimeters of one another; and
rotating the top mold member from the top mold closed configuration to the top mold open configuration;
wherein as the top mold member rotates about the molding assembly hinge axis from the top mold closed configuration to the top mold open configuration the first top mold portion and the second top mold portion of the top mold member shift away from the base mold member.

16. The method according to claim 15 , wherein the rotating one or both of a first top mold portion and a second top mold portion to the top mold closed configuration comprises rotating the first top mold portion and the second top mold portion towards one another, and towards the article.

17. The method according to claim 15 , further comprising: securing the top mol
