Patent

CA 2224285

The invention comprises a device for the manufacture of sandals. The device is formed by a last, covered by the sandal shaft which represents the upper limitation of the cavity of a mold of an injection molding tool. The molding tool is designed for molding a sole onto the shaft in an injection mold cavity, such cavity being formed by lateral parts of the mold and, if necessary, a bottom last portion. The upper edge of the lateral parts of the mold and the complementary contour of the last form a sealing zone for the cavity. In addition, there is provided within the area of the sealing zone, a seal consisting of elastic material, disposed between the last and the lateral parts of the mold. The seal encloses the last completely when the lateral parts of the mold are in their closed position.

La présente invention se rapporte à un dispositif utilisé pour fabriquer des sandales. Le dispositif se compose d'une forme couverte par la tige de sandale qui définit la limite supérieure de la cavité du moule d'un outil de moulage par injection. L'outil de moulage est conçu de manière à assurer le moulage de la semelle sur la tige à l'intérieur de la cavité du moule à injection, laquelle est formée par les parties latérales du moule et, au besoin, par une portion de forme inférieure. Le rebord supérieur des parties latérales du moule et le contour complémentaire de la forme définissent une zone de scellement dans la cavité. En outre, un matériau élastique de scellement est disposé à l'intérieur de la zone de scellement, entre la forme et les parties latérales du moule. Le matériau de scellement recouvre complètement la forme lorsque les parties latérales du moule sont en position fermée.
