Problems solved by technology

Moreover, the fixation of the magnets in the mold is not always satisfactory
[0012] As mentioned before, screwing is possible without leaving marks on the sidewall of the molded tire, it is best to remove the mold from the press to access the screws, then unscrew them, which is tedious
Then, once the insert has been cleaned or replaced, the mold must be installed and aligned inside the press again

Embodiment Construction

[0052] exist figure 1 In , an exemplary embodiment of a mold is shown, generally designated 10, for the baking or vulcanization of tyres. The mold 10 has an axis of symmetry 12 , here assumed to be vertical, which coincides with the axis of rotation of the tyre.

[0053] The mold 10 comprises two annular shells 14 , 16 facing each other axially above and below, and a crown ring of a segment 18 radially surrounding the shells 14 , 16 .

[0054] As will be described in more detail below, the housing 14, 16 of the mold comprises an insert 20 which is removably secured and which comprises marking means for molding a pattern on the sidewall of the tyre.

[0055] As known per se, the section 18 of the mold is in figure 1 The mold 10 shown in FIG. 10 moves radially between a closed position (corresponding to the tire molding position) and an open position. In the closed position, the housings 14, 16 and the plurality of segments 18 collectively define a mold cavity 22 for the tir...

Abstract

The mold element (14) comprises a main body (24), at least one insert (20), and at least one fixing device, the main body (24) being provided with all or part of one of a sidewall or a tread suitable for molding a tire a molding face (24a), at least one recess (30) formed in the molding face, said insert (20) being accommodated in said recess, said fixing means adapted to remove said insert Fixed to the main body, said insert is provided with an inner molding surface comprising marking means adapted to mold a pattern on the tyre.

Description

technical field [0001] The invention relates to the field of baking molds or vulcanization molds for vehicle tyres. [0002] More specifically, the invention relates to a mold element comprising a removable insert. Background technique [0003] The mold mainly comprises two side shells each ensuring the molding of one sidewall of the tyre, and a crown ring ensuring the molding of the tread of said tyre. The casing and the crown ring define an annular inner molding space for contact with the blank of the unvulcanized tyre. [0004] In order to mold information on tire sidewalls, it is known to use inserts fixed on a special housing of the mould. The insert includes markings corresponding to the inverse of the pattern to be molded on the sidewall, which could be, for example, technical or legal information or information allowing consumers to distinguish tire brands, or even for inventory identification Barcode, unique serial number of said tire, etc. [0005] In order to ...
