    • Outer and inner soles and a sole welt are molded onto shoe uppers. A molded outer sole is formed by injection molding plasticized thermoplastic material into a first mold cavity defined by a first mold part at an end of a pivotable mold carrier and a confronting mold plate. A molded sole welt closed on itself is formed on a last supported shoe upper by injection molding plasticized thermoplastic material into a sole welt mold cavity defined by an opposed pair of first lateral mold elements closed against the shoe upper while a second mold part at an opposite end of the mold carrier confronts the shoe upper and the lateral mold elements. The mold carrier is shifted away from the lateral mold elements and pivoted to confront the first mold part and the molded outer sole to the shoe upper. An inner sole mold cavity is formed with the molded outer sole by closing an opposed pair of second lateral mold elements located between the first lateral elements and the first mold part. A molded inner sole is formed by injection molding foamed plasticized thermoplastic material into the inner sole mold cavity. The molded outer sole may be formed by separately injection molding plasticized thermoplastic material into portions of the first mold cavity during first and second steps of the first molding cycle.
    • 外鞋底和鞋底均匀地镶嵌在鞋面上。 通过将可塑化的热塑性材料注塑成由可枢转模具托架的端部和相对的模具板的第一模具部件限定的第一模具腔体而形成模制的外底部。 通过将增塑的热塑性材料注射成型而成的鞋底边缘模腔中,在最后一个支撑的鞋面上形成一个封闭的模制底部边缘,该底部边缘模具腔由相对的一对第一侧向模具元件限定, 模具承载件的端部面对鞋面和侧面模具元件。 模具托架从侧面模具元件移开并且枢转以面对第一模具部件和模制的外底部到鞋面。 通过闭合位于第一侧向元件和第一模具部件之间的相对的一对第二侧模元件,形成具有模制的外底的内单模模腔。 通过将泡沫塑化的热塑性材料注塑成内层模具腔形成模制内底。 模制的外底可以通过在第一模制周期的第一和第二步骤期间将增塑的热塑性材料分别注塑成第一模腔的部分而形成。

    • An apparatus for molding an outer sole of elastomer and an inner sole of a mixture of isocyanate and a polyol reacting into polyurethane to shoe uppers includes a vertically movable upper cross block supporting a pivotably mounted mold carrier with a heatable first mold part at one end for the molding of outer soles, and a lower, vertically adjustable cross block has a heatable plate in contact with the first mold part. The mold carrier is pivoted such that the heatable first mold part containing the molded outer sole forms a mold cavity for an inner sole together with laterally movable mold elements and a last supported shoe upper. A vertically adjustable last body has a transfer plate which transfers the molded outer sole from the heatable first mold part for cooling before the molded outer sole is transferred back to a cooled mold part at the opposite end of the mold carrier, after which the last supported shoe upper is rotated to confront the outer sole and the lateral mold elements are closed to define a cavity for the molding of the inner sole.
    • 用于模制弹性体外底的装置和反应成聚氨酯至鞋面的异氰酸酯和多元醇的混合物的内底的装置包括可垂直运动的上横向块,其支撑可枢转地安装的模具架,其一端具有可加热的第一模具部件 外底的成型和下部可垂直调节的交叉块具有与第一模具部分接触的可加热板。 模具托架枢转,使得包含模制的外底的可加热的第一模具部件与侧向可移动的模具元件和最后支撑的鞋面形成用于内底的模腔。 可垂直调节的最后一个主体具有转印板,该转印板将模制的外底从可加热的第一模具部件转移以进行冷却,然后将模制的外底转移回模具架的相对端处的冷却的模具部件,之后最后支撑 鞋面被旋转以面对外底,并且侧模元件被关闭以限定用于内底的模制的空腔。
