Title
(EN) SHOE INJECTION MOLD AND SHOE INJECTION MOLDING METHOD USING SAME

Abstract
(EN) The present invention relates to a shoe injection mold and a shoe injection molding method using the same. The mold comprises a last mold, an outer mold, an injection nozzle and a corresponding mold opening and closing mechanism. The external mold comprises a mutually matching clamp mold and first bottom mold. The bottom of the last mold is provided with a concave injection recess. The first bottom mold is provided with an injection nozzle through-hole opposite to the position of the injection recess. After closing the mold, the injection nozzle passes through the injection nozzle hole, with an inner end thereof located in the injection recess and an outer end thereof located outside the outer mold. The method injects a molten plastic material into the injection recess via the injection nozzle, enabling a plastic forming material to press a stocking from a stocking inner side against an inner surface of the outer mold until the plastic material fills a shaping cavity. The invention can produce injection-formed shoes with various fabrics, and the shoes have a good feel, a simple production process and a low cost, favorably satisfying consumer needs.
(FR) La présente invention concerne un moule d’injection pour chaussure et un procédé de moulage de chaussure par injection l’utilisant. Le moule comprend un dernier moule, un moule externe, une buse d’injection et une ouverture de moule correspondante ainsi qu'un mécanisme de fermeture. Le moule externe comprend un moule de serrage mutuellement correspondant et un premier moule inférieur. La partie inférieure du dernier moule est prévue avec un renfoncement d’injection concave. Le premier moule inférieur est prévu avec un trou traversant de buse d’injection opposé à la position du renfoncement d’injection. Après la fermeture du moule, la buse d’injection passe à travers le trou de buse d’injection, son extrémité interne étant située dans le renfoncement d’injection et son extrémité externe étant située à l’extérieur du moule externe. Le procédé injecte un matériau de matière plastique moulée dans le renfoncement d’injection via la buse d’injection, ce qui permet à un matériau de mise en forme de matière plastique de comprimer une résille depuis une face interne de résille contre une surface interne du moule externe jusqu’à ce que la matière plastique remplisse une cavité de mise en forme. L’invention peut produire des chaussures formées par injection avec divers textiles, et les chaussures présentent un bon toucher, un procédé simple de production et un faible coût, ce qui satisfait de manière favorable les besoins des consommateurs.
(ZH) 本发明涉及一种鞋的注塑成型模具和一种采用该模具的鞋的注塑成型方法,所述模具包括楦模、外模、注料嘴及相应的开合模机构,所述外模包括相互配套的夹模和第一底模,所述楦模的底部设有内凹的注料槽,所述第一底模上设有与所述注料槽位置相对的注料嘴通孔,合模后所述注料嘴穿过所述注料嘴孔,里端位于所述注料槽内,外端位于所述外模外,所述方法为通过所述注料嘴将熔融的塑性材料注入所述注料槽,使塑形材料从所述袜套的里侧将袜套挤压在所述外模的内表面上,直至塑料材料充满型腔。采用本发明可以制备出各种面料的注塑鞋,并且鞋的质感好,制备工艺简单,成本低,有利于更好地满足人们的需要。
