摘要:
The vulcanizing press for curing green tire blanks having: a component, at least one inductor comprising an armature having two free ends exhibiting soles which are able to close an electromagnetic loop through the component, and for each sole, at least one connecting element connecting the sole to the component and forming between the two of them at least one space, the connecting element or elements associated with the sole occupying in total less than half of a length of the sole.
摘要:
Segmented mold for molding and vulcanizing a tire of given diameter, having shells and segments collaborating to withstand the internal pressure and remain in the closed position without assistance from additional components, having at its lateral edges a projection extending radially inwards, equipped with a lip extending axially towards the inside of the mold, having a frustoconical surface inclined at an angle α wherein extensions of the line of each frustoconical surface intersect on the radially internal side of the segment, each shell having a projection extending radially outwards and a lip having a frustoconical surface inclined by the same angle α, and containing force-limiting element having a stop and a housing positioned respectively in the radial extension of each of the projections and each having a bearing surface, to come into contact with one another when internal pressure in the mold exceeds a given threshold.

Segmented mold for molding and vulcanizing a tire of given diameter (DS), having a width (L) and a diameter (J) at the interconnect point (E), comprising shells and segments collaborating to withstand the internal pressure and remain in the closed position without assistance from additional components, in which mold each segment comprises at its lateral edges a projection extending radially inwards, which projection is equipped with a lip extending axially towards the inside of the mold and having an inclined frustoconical surface of given angle (α) with respect to the axis (XX′) of the mold such that the extensions of the line of each frustoconical surface on a meridian plane intercept on the radially internal side of the segment concerned, and in which mold each shell comprises a projection extending radially outwards and provided with a lip having a frustoconical surface inclined by the same angle α with respect to the axis XX′ of the mold. The distance (α) comprised between a straight line (tt′) parallel to the axis of the mold and passing through the point (T) of application of the resultant of the forces (F) of contact between the shells and the segments, and a straight line (ss′) parallel to the axis of the mold situated in the extension of the internal face of the resistant segment is equal to k * 0.42 * D s ( L J ) 2 , with a coefficient k comprised between 0.8 and 1.4.
