ラストモールドと、２つのサイドモールドと、ボトムモールドとを型組みして形成される空隙に合成樹脂材料を充填し、合成樹脂材料を固化させて少なくとも甲部と靴底部を同時に成形する射出成形靴の製造方法において、ラストモールドに対し左右方向に接近離隔移動するサイドモールドには甲部に対応する部分に複数のピンが設けてあり、各モールドを型組みするとともに、これらのピンをサイドモールドの表面より突出させてラストモールドに被せた裏布材に適宜の圧力で当接して合成樹脂材料の充填空隙を形成し、この空隙に合成樹脂材料を充填し、合成樹脂材料が固化した後、これらのピンをサイドモールドの表面より没しさせ、その後各モールドを離隔することにより、固化した樹脂の甲部に複数の通気孔を形成することを特徴とする射出成形靴の製造方法。
Injection-molded shoes in which a synthetic resin material is filled in a gap formed by assembling a last mold, two side molds, and a bottom mold, and the synthetic resin material is solidified to simultaneously mold at least the upper part and the shoe bottom part. In this manufacturing method, the side mold that moves close to and away from the last mold in the left-right direction is provided with a plurality of pins in the part corresponding to the upper part, and each mold is assembled and these pins are attached to the side mold. After filling from the surface and covering the last mold with the appropriate pressure, contact with the appropriate pressure to form a filling space of the synthetic resin material, and then filling the space with the synthetic resin material and solidifying the synthetic resin material, these A plurality of air holes are formed in the back of the solidified resin by immersing the pins of the mold from the surface of the side mold and then separating each mold. Manufacturing method of injection-molded shoes to be.
少なくとも通気孔が形成される位置及びその周辺の裏布材は、耐水性と透湿性又は通気性とを有する膜状のフィルムを有してなり、フィルムを合成樹脂材料に接触するようにラストモールドに被せられる裏布材である請求項１記載の射出成形靴の製造方法。
At least the position where the air holes are formed and the surrounding lining material have a film-like film having water resistance, moisture permeability or air permeability, and the last mold so that the film comes into contact with the synthetic resin material method of manufacturing an injection molding shoes a backing cloth material is claimed in claim 1, wherein for covering the.
請求項１又は請求項２の射出成形靴の製造方法によって製造される射出成形靴であって、形成された通気孔に多孔樹脂弾性体を充填してなることを特徴とする射出成形靴。
An injection-molded shoe manufactured by the method of manufacturing an injection-molded shoe according to claim 1 or 2 , wherein the formed vent hole is filled with a porous resin elastic body.
