Abstract

A sole mold for manufacturing a sole from a plurality of particles includes at least one first opening for supplying the particles, and at least two second openings for supplying a gaseous and/or liquid medium to bond and/or fuse the particles together. At least a portion of the sole mold is manufactured by an additive manufacturing method.

Claims

1. A sole mold for manufacturing a sole from a plurality of particles comprising:

at least one first opening for supplying the particles; and

at least two second openings for supplying at least one of a gaseous medium and a liquid medium to perform at least one of bonding and fusing the particles together;

wherein at least a portion of the sole mold comprising the at least two second openings is manufactured by an additive manufacturing method; and

wherein the at least two second openings have a largest dimension smaller than the average size of the particles to be molded in the shoe mold.

2. The sole mold of claim 1, wherein the at least two second openings have a smaller length than an average size of the particles to be molded in the sole mold.

3. The sole mold of claim 1, wherein the largest dimension of the second openings is equal to or less than approximately 5.0 mm.

4. The sole mold of claim 1, wherein the largest dimension of the second openings is equal to or less than approximately 4.0 mm.

5. The sole mold of claim 1, wherein the largest dimension of the second openings is equal to or less than approximately 3.0 mm.

6. The sole mold of claim 1, wherein the largest dimension of the second openings is from approximately 0.1 mm to 1.0 mm.

7. The sole mold of claim 1, wherein at least a portion of the sole mold comprises a thickness equal to or less than approximately 10 mm.

8. The sole mold of claim 1, wherein at least a portion of the sole mold comprises a thickness equal to or less than approximately 6 mm.

9. The sole mold claim 1, wherein at least a portion of sole mold comprises a thickness equal to or less than approximately 3 mm.

10. The sole mold of claim 7, wherein the portion is provided in a side wall of the sole mold.

11. The sole mold of claim 7, wherein the portion comprises substantially the complete sole mold.

12. The sole mold of claim 1, wherein the sole mold further comprises a top part, a bottom part and a side wall, wherein the at least two second openings are provided in the side wall.

13. The sole mold of claim 12, wherein the at least two second openings are further provided in the top part and the bottom part.

14. The sole mold of claim 1, further comprising at least one of at least one recess and at least one projection to position a pre-manufactured outsole.

15. The sole mold of claim 14, wherein the at least two second openings are arranged adjacent to at least one of the at least one recess and the at least one projection.

16. The sole mold of claim 1, wherein the at least two second openings are arranged in a substantially regular pattern.

17. The sole mold of claim 1, further comprising a means for holding a supporting element inside the sole mold.

18. The sole mold of claim 1, further comprising a means for ejecting a manufactured sole from the sole mold.

19. An arrangement of a plurality of sole molds according to claim 1.
