The mold consists of three basic parts, namely: the moving half, the floating cavity plate and the feed plate respectively. Figure 5-1 Opening sequence of a basic underfeed type mold 图5-1 基本结构模具的开模顺序 Lesson 5 Basic Underfeed Mold The moving half consists of the moving mold plate assembly, support blocks, backing plate, ejector assembly and the pin ejection system. Thus the moving half in this design is identical with the moving half of basic molds. 动模部分包括动模板组件、支承块、支承板，推出机构和顶杆推出系统。这样设计的动模部分与最基本的模具结构中的动模部分相同。 Lesson 5 Basic Underfeed Mold The floating cavity plate, which may be of the integer or insert-bolster design, is located on substantial guide pillars (not shown) fitted in the feed plate. These guide pillars must be of sufficient length to support the floating cavity plate over its full movement and still project to perform the function of alignment between the cavity and core when the mold is being closed. Guide bushes are fitted into the moving mold plate and the floating cavity plate respectively. 浮动型腔板通过导柱（图5-1中没有示出）固定在定模板上，设计形式可以是整体式，也可以是镶拼式。导柱必须有足够的长度，（以便模具工作时）支撑浮动型腔板完成开合动作，并在模具合模时完成对型腔和型芯的找正作用。导套分别安装在动模板和浮动型腔板上。 Note ①句中的made from plastic为objects的后置定语；全句可译为：两个方向之间略带角度，仔细检查大多数家用塑料制品都会采用
