Title (EN) MOULD AND METHOD FOR PRODUCING FOOTWEAR
(FR) SYSTÈME ET PROCÉDÉ DE FABRICATION DE CHAUSSURE
Abstract:
(EN) The present invention relates to a mould (10) for producing footwear (1) by direct injection onto an upper (2) of a sole (3), comprising a tread (5) and a midsole (4), wherein the midsole (4) is composed of a first layer (6) and a second layer (7). The mould (10) comprises a base (12), a pair of first half-rings (16), a lid (18), a pair of second half-rings (20) and a mould last (22). The first half-rings (16) are designed to be arranged close together such that they abut against the base (12) and against the lid (18), so as to form a first mould cavity for moulding the first layer (6) of the midsole (4). While the first half-rings (16) are abutting against the base (12), the second half-rings (20) are designed to be arranged close together, such that they lie over the half-rings (16) and abut against the upper (2), fitted onto the mould last (22), so as to form a second mould cavity for moulding the second layer (7) of the midsole (4). In accordance with the invention the first half-rings (16) are provided with guiding means (24) so that they can be moved away from and towards each other and rotate about an axis of rotation (C). The invention also relates to a method for producing footwear by direct injection onto an upper, which may be performed by means of the mould according to the invention.
(FR) La présente invention concerne un moule (10) pour fabriquer une chaussure (1) par injection directe sur une tige (2) d'une semelle (3), comprenant une semelle d'usure (5) et une semelle intercalaire (4), la semelle intercalaire (4) étant composée d'une première couche (6) et d'une seconde couche (7). Le moule (10) comprend une base (12), une paire de premiers demi-anneaux (16), un couvercle (18), une paire de seconds demi-anneaux (20) et une forme de moule (22). Les premiers demi-anneaux (16) sont conçus pour être disposés à proximité l'un de l'autre de telle sorte qu'ils viennent en butée contre la base (12) et contre le couvercle (18), de manière à former une première cavité de moule pour mouler la première couche (6) de la semelle intercalaire (4). Pendant que les premiers demi-anneaux (16) sont en butée contre la base (12), les seconds demi-anneaux (20) sont conçus pour être disposés à proximité l'un de l'autre, de sorte qu'ils reposent sur les premiers demi-anneaux (16) et viennent en butée contre la tige (2), ajustée sur la forme de moule (22), de manière à former une seconde cavité de moule pour mouler la seconde couche (7) de la semelle intercalaire (4). Selon l'invention, les premiers demi-anneaux (16) sont pourvus de moyens de guidage (24) de sorte qu'ils peuvent être éloignés l'un de l'autre et tourner autour d'un axe de rotation (C). L'invention concerne également un procédé de fabrication de chaussure par injection directe sur une tige, qui peut être mis en œuvre au moyen du moule selon l'invention.
