    • Using a mold equipped with a rib-forming member capable of moving forward and backward relative to the mold cavity, produced is a lightweight, hollow resin molding having a reinforcing rib structure in the hollow area, from a fiber-containing thermoplastic resin having a fiber content of from 10 to 70% by weight. To produce the molding, a melt of a fiber-containing thermoplastic resin is injected into the mold cavity or is injected thereinto under compression, then the movable mold member is moved backward in the direction in which the mold cavity is expandable, and after the start of the mold member moving, a gas is introduced into the resin melt. Even though the molding has a hollow structure and has a large surface area, it has good stiffness and high strength, and has good appearances. The weight of the molding can be well controlled and reduced to any desired degree. The molding has many applications in various fields.
    • 使用具有能够相对于模腔前后移动的肋形成构件的模具,是具有在中空区域中具有加强肋结构的轻质中空树脂模制品,其具有纤维的含纤维热塑性树脂 含量为10〜70重量%。 为了制造模制品,将含纤维的热塑性树脂的熔体注射到模腔中或在压缩下被注入,然后可动模具沿模腔扩展的方向向后移动,并且在开始之后 模具构件移动时,将气体引入到树脂熔体中。 即使成型件具有中空结构并且具有大的表面积,其具有良好的刚度和高强度,并且具有良好的外观。 模制品的重量可以很好地控制并减少到任何所需的程度。 该模具在各个领域有很多应用。

    • The present invention is a general structural member assembly. A basic structural unit of the present invention has two adjacent shafts, both further having a cross sectionally triangular shape with a longitudinal side completely or substantially mostly removed to form legs. The leg ends are formed or machined such that they present two outward surfaces generally parallel to the the open face of a first adjacent shaft. The outward surfaces of the leg ends are then positionally fixed, albeit with some flexible movement in some embodiments, to generally have a parallel and longitudinal interface with the longitudinal outside edges of a solid side of a second shaft. Additional shafts may be added in this open side opposed to solid side assembly.
    • 本发明是一般的结构件组件。 本发明的基本结构单元具有两个相邻的轴,两个相邻的轴进一步具有横截面三角形形状,其纵向侧面完全或基本上大部分被去除以形成腿部。 腿部端部被形成或加工成使得它们呈现大致平行于第一相邻轴的开口面的两个外表面。 然而,在一些实施例中,尽管在一些实施例中具有一些柔性的运动,腿端的外表面然后是位置固定的,以通常具有与第二轴的实心侧的纵向外边缘的平行和纵向界面。 可以在与实心侧组件相对的该敞开侧添加附加的轴。
