Abstract
(EN)
The present invention enables a high-quality midsole to be provided, by: enabling a through hole, which passes laterally through a midsole used for a shoe, to be integrally formed; preventing traces of forming the through hole from being left in the through hole and on the periphery of the through hole; providing a shaft mold crossing the inner space of upper and lower molds; forming extending portions such that the ends of the shaft mold extend beyond the boundary of the inner space; and seating the extending portions in press recesses of the upper and lower molds to seal the insides of the molds so as to prevent raw material from leaking from inside the molds when foaming and forming a midsole, prevent parting lines and burrs from forming on the inner surface of the through hole passing laterally through the midsole, and prevent forming traces from remaining. Also, by providing the structure of shaft molds to be symmetrical on both sides and manufacturing a pair of midsoles under the same forming conditions, size defects and the like do not occur and a pair of midsoles has the same size, weight, and elasticity.

La présente invention concerne une semelle intermédiaire de haute qualité fabriquée par le procédé comprenant les étapes consistant à former un trou traversant qui passe à travers une semelle intermédiaire utilisée pour une chaussure latéralement destinée à être formée d'une seule pièce ; à empêcher des traces de formation du trou traversant d'être laissées dans le trou traversant et sur la périphérie du trou traversant ; à fournir un moule d'arbre croisant l'espace intérieur de moules supérieur et inférieur ; à former des parties s'étendant, de telle sorte que les extrémités du moule d'arbre s'étendent au-delà de la limite de l'espace intérieur ; et à poser les parties s'étendant dans des évidements de presse des moules supérieur et inférieur pour sceller les parties intérieures des moules de façon à empêcher les matières premières de fuir depuis l'intérieur des moules lors du processus de moussage et de formation d'une semelle intermédiaire, à empêcher des lignes de partition et des bavures de se former sur la surface intérieure du trou traversant passant au travers de la semelle intermédiaire latéralement, et à éviter la présence de traces résiduelles. De plus, en fournissant la structure de moules d'arbre symétriques des deux côtés et en fabricant une paire de semelles intermédiaires dans les mêmes conditions de formation, des défauts de taille et similaire ne se produisent pas et une paire de semelles intermédiaires à une taille, un poids et dune élasticité identiques.

본 발명은 신발에 사용되는 미드솔에 측방으로 관통된 통공이 일체로 성형되도록 하면서 통공과 통공의 주변에 성형흔적이 나타나지 않도록 한 것으로, 상,하부금형의 내공간을 가로지르도록 축 금형을 구비하고 그 축 금형의 단부를 내공간 경계를 초과하도록 연장부를 형성하면서 연장부가 상,하부금형의 프레스홈에 안착되어 금형 내부가 밀폐되도록 함으로써 미드솔을 발포 성형할 때 금형 내부에서 원료가 새는 것을 방지하고 미드솔을 측방향으로 관통하는 통공 내면에 파팅라인과 버가 발생하지 않고 성형흔적이 남지 않도록 하며 고품질의 미드솔을 제공할 수 있도록 한 것이다. 또한, 축 금형의 구조를 양측으로 대칭되게 구비하여 동일한 성형조건 하에서 한 쌍의 미드솔을 제작함으로써 치수불량 등이 발생하지 않고 한 쌍의 미드솔이 동일한 크기, 중량, 탄성을 갖도록 한 것이다.
