Application: Flexible mold segment with sipe element having a projection for use in forming a tire (Patent ID: US20240059037A1)
The patent filed by Compagnie Generale des Etablissements Michelin describes a mold segment for forming a tire, consisting of a sipe element with projections on one side face, and a mold segment base made of a more flexible material that receives the sipe element. The mold segment base defines cavities for the projections and is used to produce a plaster cast segment for tire formation, not a production mold segment base. The sipe element and mold segment base are designed to create an interference fit for precise molding.
The mold segment base is made of polysulfide castable mold rubber, with cavities spaced from the upper and lower surfaces. The sipe element's projections are longer in the length direction and engage the mold segment base through lips. The mold segment base is poured on a master mold and formed from a preliminary sipe projection, with the possibility of additive manufacturing for the sipe element. Additionally, the mold segment base includes a bead that forms a tire groove, with the sipe element engaging the side wall of the bead for tire molding.
