| 发明名称 | Molding element of a mold for a tire, comprising a plurality of holes | ||
| 摘要 | A molding element for a tire mold manufactured from a metallic powder fused together layer by layer, having a body, comprising a first surface intended to mold all or part of a tread surface of the tire and a second surface opposite to the first surface and intended to be in contact with another part of the mold, the thickness (E) of the body of the molding element being between 1 and 6 millimetres. The molding element has at least one cavity opening onto the second surface of this body. The molding element also has a plate positioned across the cavity and formed as one with the body of the molding element, being at the same level as the first surface of the body, and having at least one hole allowing air to pass between the first surface of the molding element and the second surface thereof. | ||

| 主权项 | 1. A molding element for a tire mold manufactured from a metallic powder fused together layer by layer, the molding element comprising: a body, this body comprising: a first surface intended to mold all or part of a tread surface of the tire, anda second surface opposite to the first surface and intended to be in contact with another part of the mold, wherein the body has a thickness (E) between 1 and 6 millimetres, at least one cavity opening onto the second surface of this body, a plate positioned across the at least one cavity and formed as one with the body of the molding element, wherein this plate is at the same level as the first surface of the body, and wherein the plate comprises at least one hole allowing air to pass between the first surface of the molding element and the second surface thereof, a lateral surface connecting the first surface of the body of the molding element to the second surface thereof, a porous area connecting the cavity to the lateral surface, this porous area forming all or part of the second surface of the body of the element and comprising a plurality of pores that allow air to pass and generate a voids volume which is greater than 20%. | ||
