    • A mold opening and closing mechanism for an I.S. machine which has a pair of mold support mechanisms supported for horizontal displacement between a retracted position and an advanced position. These support mechanisms are linearly displaced by a drive assembly which includes a lead screw, a housing secured to the section frame for supporting the lead screw, a motor coupled to the lead screw, nuts operatively associated with the lead screw, and links interconnecting the nuts with their associated mold support mechanism. The housing has a rear wall defining a flat surface, and the nuts have flat rear bearing surfaces with a selected spacing therebetween when the mold support mechanism is fully retracted. The lead screw has a rigidity selectively chosen so that when the mold mechanism is displaced to the advanced position into engagement with the other mold support mechanism, with a predetermined force, the lead screw will deflect to establish engagement between the flat bearing surfaces and the rear flat wall surface of the housing which is secured to the frame, whereby the mold support mechanism will be part of a continuous solid structure extending from the section frame, up the housing of each of the drive assemblies, across the nuts and the links of each drive assemblies, and across mold support mechanisms thereby positively preventing the vertical or horizontal displacement of the engaged mold support mechanisms from forces applied thereto.
    • 一种用于I.S.的模具打开和关闭机构 机器具有支撑在缩回位置和前进位置之间的水平位移的一对模具支撑机构。 这些支撑机构由驱动组件线性移位,该驱动组件包括导螺杆,固定到用于支撑导螺杆的截面框架的壳体,联接到丝杠的马达,与导螺杆可操作地相连的螺母,以及将螺母 与其相关的模具支撑机构。 壳体具有限定平坦表面的后壁,并且当模具支撑机构完全缩回时,螺母具有平坦的后支承表面,其间具有选定的间隔。 导螺杆具有选择性选择的刚性,使得当模具机构被移动到前进位置以与另一个模具支撑机构接合时,以预定的力,导螺杆将偏转以在平坦的支承表面和后部 壳体的平坦壁表面固定到框架上,由此模具支撑机构将是连续的实心结构的一部分,其从分段框架延伸出,每个驱动组件的壳体越过螺母和每个的连杆 驱动组件和模具支撑机构,从而可以肯定地防止所接合的模具支撑机构从施加到其上的力的垂直或水平位移。
