Abstract
The subject invention relates to a mold segment comprising a tread molding element for manufacturing a tire wherein the tread molding element comprises a shell and an infill, wherein the shell has a first wall with a negative tread pattern extending from its external surface for molding the tread, a second wall opposed to the first wall, and lateral walls; wherein the infill is a fluid-permeable structure defining a fluid-permeable infill; and wherein at least one of a lateral wall and the second wall comprises at least one fluid passage passing through the lateral wall or the second wall.
Claims16
A mold segment comprising a tread molding element for manufacturing a tire, wherein the tread molding element comprises a shell and an infill, the shell having i) a first wall with a negative tread pattern extending from its external surface for molding the tread, ii) a second wall opposed to the first wall, and iii) lateral walls;
- wherein the infill is a fluid-permeable structure defining a fluid-permeable infill;
- wherein at least one selected from a lateral wall and the second wall comprises at least one fluid passage passing through the lateral wall or the second wall and is fluidly connected to the fluid permeable infill;
- wherein the fluid-permeable structure is selected from a fluid-permeable lattice structure, a bionic structure, and a bionic structure which is formed by a lattice structure;
- and wherein the negative tread pattern of the first wall comprises one or more of sipes and blades which are integral with the first wall and at least one blade is hollow and open to an internal surface of the first wall.
A mold segment comprising a tread molding element for the manufacture of a tire wherein the tread molding element comprises a shell and an infill, and wherein the shell has a first wall with a negative tread pattern extending from its external surface for molding the tread, a second wall opposed to the first wall, and lateral walls;
- wherein the infill is a fluid-permeable structure defining a fluid permeable infill;
- wherein the shell is integral with the fluid-permeable infill;
- wherein the first wall comprises one or more vents which pass through the first wall and are open to the fluid permeable infill;
- and wherein at least one selected from a lateral wall and the second wall comprises at least one fluid passage which passes through the lateral wall or the second wall and is open to the fluid permeable infill;
- wherein the one or more vents have a width ranging from 10 μm to 500 μm.
