    • According to an aspect, there is disclosed a hot runner system (100), comprising: a first surface (205) being elastically deformable; a second surface (210) forming, in cooperation with the first surface (205), a melt-leakage gap (215) being located between the first surface (205) and the second surface (210); and an active material (220) being: (i) coupled with the first surface (205), (ii) held normally stationary, (iii) configured to be operatively coupled with a signal source (225), and (iv) configured to elastically deform in response to receiving a signal from the signal source (225), upon elastic deformation of the active material (220), the first surface (205) becomes moved toward the second surface (210) such that a size (235) of the melt-leakage gap (215) becomes controlled.
    • 根据一方面,公开了一种热流道系统(100),包括:可弹性变形的第一表面(205) 与所述第一表面(205)协作地形成位于所述第一表面(205)和所述第二表面(210)之间的熔体泄漏间隙(215)的第二表面(210)。 并且活性材料(220)是:(i)与所述第一表面(205)耦合,(ii)保持正常静止,(iii)被配置为与信号源(225)可操作地耦合,以及(iv) 响应于从信号源(225)接收信号而弹性变形,在活性材料(220)弹性变形时,第一表面(205)朝向第二表面(210)移动,使得(235)的尺寸 熔体泄漏间隙(215)变得受控。

    • The present invention provides a multi-ply molding hot-runner mold including a plurality of nozzle bodies for injecting a plurality of different resin materials to form a multi-ply product. The hot-runner mold comprise's a plurality of hot-runner blocks each having a runner for conducting each resin material into the corresponding nozzle body. The hot-runner blocks are stacked one above another through a thermal insulation layer therebetween. Each of the hot-runner blocks includes temperature control means for maintaining the hot-runner block at its own inherent molding temperature. Connecting blocks for conducting the resin material from the lower block to the upper block are provided between each adjacent hot-runner blocks. Between each adjacent hot-runner blocks, there are provided only holding members for holding the blocks together and the connecting blocks except thermal insulation layers therebetween.
    • 本发明提供一种多层成型热流道模具,其包括多个用于注入多种不同树脂材料以形成多层产品的喷嘴体(10)。 热流道模具包括多个热流道块(30,40),每个热流道块具有用于将每个树脂材料导入相应的喷嘴体(10)的流道(32,42)。 热流道块(30,40)通过其间的绝热层(50)层叠在另一个之上。 每个热流道块(30,40)包括用于将热流道块保持在其自身固有成型温度的温度控制装置。 在每个相邻的热流道块之间设置有用于将树脂材料从下部块(40)导引到上部块(30)的连接块(52)。 在每个相邻的热流道块之间,仅设置有用于将块保持在一起的保持构件和除了绝热层之外的连接块。
