Definitions
- a molding element having a plurality of ribs and at least one measuring zone without ribs.
- the present invention relates to the field of vulcanizing molds for tires.
- the invention particularly relates to molds for molding snow tires having on their tread a large number of fine grooves.
- Incisions are cuts that extend into the depth of the tread and open into the tread surface forming ridges. These ridges are particularly useful for improving grip on snowy or icy roads.
- a tire mold comprises a plurality of separate molding elements which, by relative approximation, delimit a generally toroidal molding space.
- a radial offset between the various molding elements it is necessary for the radial offset between the various molding elements to be limited once they are brought closer together.
- it is important to control the thickness of the molding elements For this, it is known to control the thickness of the molding elements using a three-dimensional measuring machine.
- the three-dimensional measuring machine comprises a fixed support table and a probe.
- the control operation is carried out in the following manner: the molding element is placed on the support table and then, using the mobile probe, various measurement zones are probed on the molding element. By palpating adequate measurement areas, it is possible to determine at a plurality of points, the thickness of the molding element. By comparing these measured thickness values with reference thickness values, it can be determined whether the molding element is compliant or non-compliant.
- the invention relates to a molding element for a tire mold comprising a tread provided with a plurality of blocks. Each block has a contact surface intended to come into contact with a roadway during a taxi.
- the molding element also has a molding surface for molding the contact surfaces of the blocks.
- the molding surface comprises a plurality of ribs for molding thin grooves in the blocks. These ribs have a height of between 0.005 and 1 mm, a width of between 0.01 mm and 0.3 mm and the pitch of the ribs is between 0.1 and 2 mm.
- the surface of molding comprises at least one measuring zone without ribs able to receive measuring means. This measurement zone generally has the shape of a disc whose diameter is greater than 3 mm.
- the invention therefore consists in providing at least one specific area on the molding surface of the molding element to make measurements using a probe of a three-dimensional measuring machine.
- This specific area is devoid of ribs and has a shape adapted to the spherical shape of the probe of the machine and the diameter of this probe which is between 1 mm and 2 mm. This guarantees a greater facility for coming to feel the molding element without encountering ribs. The accuracy in determining the thickness of the molding element at this measurement zone is then improved.
- the molding element has two edges circumferentially delimiting the molding surface, each of said edges being adapted to come into contact with an edge of another molding element.
- the center of the measurement zone is at most 15 mm apart with one of said edges.
- the invention also relates to a molding element for a tire mold comprising a tread provided with a plurality of blocks. Each block has a contact surface intended to come into contact with a roadway during a taxi.
- the molding element also has a molding surface for molding the contact surfaces of the blocks. This molding surface has a roughness of between 0.005 mm and 0.02 mm.
- the molding surface comprises at least one measurement zone capable of receiving measuring means.
- the measuring area has overall the shape of a disc whose diameter is greater than 3 mm and the measurement zone has a roughness of between 0.002 mm and 0.003 mm.
- Another object of the invention relates to a mold comprising a molding element as described above. Another object of the invention relates to a snow tire molded and vulcanized from this mold.
- FIG. 1 represents a schematic perspective view of a molding element having a plurality of ribs
- Figure 2 shows a partial sectional view of the molding surface of the molding element of Figure 1
- - Figure 3 shows a schematic perspective view of a molding element without ribs having a specific surface condition.
- FIG. 1 shows a schematic perspective view of a molding element according to a first embodiment of the invention.
- the molding element comprises slats 3 and a molding surface 5.
- the slats 3 are intended to mold grooves in the tread of a molded tire.
- the grooves are cutouts whose width is greater than 2 mm and the height is greater than 4 mm. These grooves delimit blocks of rubber in the tread of the tire.
- the molding surface 5 is intended to mold the contact surfaces of the blocks of the tread.
- the contact surface of a block is the surface that will come into contact with the roadway during a taxi.
- the molding surface 5 here comprises a plurality of ribs 7 for molding thin grooves in the tread.
- the ribs are parallel to each other and regularly distributed. More particularly, the pitch of the ribs is between 0.1 and 2 mm.
- the molding surface 5 also comprises at least one zone without ribs 9 delimited by ribs 7.
- the zone without rib is intended to receive measuring means such as a probe of a three-dimensional measuring machine.
- the zone without ribs 9 has the overall shape of a disk and the diameter of this disk is greater than 3 mm. To avoid reducing the performance of the tire on a snowy or icy road, the area of the zone without ribs is limited. For example, the area of this area is less than 40 mm 2 .
- the measuring zone 9 is situated close to an edge 1 1 circumferentially delimiting the molding element 1. More precisely, the center of the measuring zone 9 is located at a distance of less than 15 mm per In this way, the distance between the center of the zone 9 and a median plane dividing the molding element into two parts of the same transverse width is less than 15 mm.
- FIG. 1 shows a partial sectional view of the molding surface 5 of Figure 1.
- the height H of the ribs is between 0.005 and 1 mm and the width L of the ribs is between 0.01 mm and 0.3 mm.
- the section of the ribs here has a rectangular shape. Alternatively, the section of the ribs is different. For example, the section of the ribs can be square, triangular, sinusoidal, trapezoidal or sawtooth.
- FIG. 3 shows a perspective view of a molding element 1 according to another embodiment.
- the ribs are replaced by a particular Ra roughness.
- the molding surface 5 has a roughness Ra of between 0.005 mm and 0.02 mm. This roughness can be obtained by a particular surface treatment operation such as sanding.
- the molding surface 5 also comprises at least one measurement zone 9 intended to receive measuring means.
- the measuring zone 9 has a roughness Ra less than the rest of the molding surface.
- the roughness of the measurement zone 9 is here between 0.002 mm and 0.003 mm. This roughness corresponds to the initial surface state of the molding element, that is to say to the surface state of the molding element when it is separated from the plaster matrix.
- the measurement zones are protected by steel pellets so that these measurement zones retain their low roughness.
- the molding element is placed on a support table belonging to the three-dimensional measuring machine.
- a second step several measurements are made on the outer surface 13 of the molding element, with reference to FIG. 1. From these measurements, the three-dimensional measuring machine is able to model this external surface 13.
- the coordinates of a point belonging to a measurement zone 9 are determined. By comparing the coordinates of this point with the modeling of the external surface 13, the three-dimensional measuring machine is able to calculate the thickness E of the molding element at the measurement zone 9.
- Figure 1 has ribs extending mainly in a transverse direction.
- the ribs may extend in an oblique direction, for example, at an angle of 45 ° to the transverse direction.
