Abstract
A method of using a marriage mold includes providing an upper plate having a first wall and at least one second wall, and a lower plate having a marriage cavity and a top wall. At least two midsole components are provided, which are made of a first material, and each have a first region and a void structure. The at least two midsole components are positioned into the marriage cavity. The upper plate is secured to the lower plate such that the first wall and the top wall form a seal. The at least two midsole components are joined together to form a midsole having a second void structure.
Claims20
A method of using a marriage mold, comprising:
- providing an upper plate with a first wall;
- providing a lower plate with a marriage cavity and a top wall;
- molding a first midsole component by a first mold, the first midsole component having first channels therein made by mandrels that have a cross-sectional shape that matches the cross-sectional shape of the first channels;
- molding a second midsole component by a second mold, the second midsole component having second channels therein made by mandrels that have a cross-sectional shape that matches the cross-sectional shape of the second channels;
- and
- molding an outsole made with an outsole mold,
- wherein the first and second midsole components are made of the same material, wherein the marriage mold is configured to receive the first and second midsole components,
- wherein the outsole is inserted into the marriage mold with the two midsole components,
- wherein the upper plate is secured to the lower plate such that the first wall and the top wall form a seal,
- wherein the midsole components and the outsole are subjected to heat, and
- wherein the assembly of midsole components are configured to join the outsole in the marriage mold in order to form a sole.
A method of using a midsole components mold, comprising:
- providing an upper plate with a first wall, and a plurality of mandrels that project from the first wall;
- and
- providing a lower plate with a top wall, a body, a plurality of exterior walls, and at least one cavity with at least one corresponding cavity wall,
- wherein the upper plate is secured to the lower plate to form a seal,
- wherein at least one midsole component is formed in the at least one cavity, and is formed of a first material and has a void structure when a liquid plastic material is injected, poured, or sprayed into the at least one cavity,
- wherein the plurality of mandrels is removably inserted into a plurality of mandrel passages, and
- wherein each of the plurality of mandrel passages includes an axis that points to a center-point such that the plurality of mandrel passages intersects with each other.
