    • A die assembly including an upper male mold (42), an annular cutting blade (46), and pressure plate (80) carried by the upper plate (40) of an upper die set (18); and a female mold (24) secured to the lower plate (22) of a lower die set (16). The blade (46) is positioned in surrounding relation to the male mold (42); the pressure plate (80) is positioned in surrounding relation to the blade (46); and an annular seal (48) encircles male mold (42) within blade (46). The upper die set (18) clamps a sheet of component material (90) positioned over the female mold (24) and is moved downwardly into the cavity (24a) by selective slippage controlled by selective adjustment of the pressure plate (80). Stop means (30) are provided to delimit the downward movement of the male mold (42) whereafter a lost motion connection allows the die (18) to continue downwardly and the cutter blade (46) to trim the sheet edge with resin being injected through the female mold to permeate sheet material (90).
    • 一种模具组件,包括由上模具(18)的上板(40)承载的上阳模(42),环形切割刀片(46)和压板(80)。 以及固定到下模组(16)的下板(22)的阴模(24)。 刀片(46)定位成与阳模(42)相关联。 压板(80)定位成与叶片(46)相关联。 和环形密封件(48)围绕叶片(46)内的阳模(42)。 上模组(18)夹住位于阴模(24)上方的一片部件材料(90),并且通过选择性地调节压板(80)控制的选择性滑动而向下移动到空腔(24a)中。 提供止动装置(30)以限定阳模(42)的向下运动,之后空运动连接允许模具(18)向下延伸并且切割刀片(46)在树脂被注入的状态下修整片材边缘 阴模渗透片材(90)。

    • A unique dynamic seal assembly for use in a mold structure for encapsulating a glass window assembly (30) with a gasket (46). A seal assembly resiliently supports the window assembly (30) and coorperates with mold structure (31) for defining a gasket forming cavity. The mold structure (31) includes two cooperating mold sections (32), (33), each of which can be provided with a groove (37), (42) for receiving a separate dynamic seal assembly. Each seal assembly includes a sealing body (36), (41) having a sealing surface (36a), (41a) which faces and sealingly contacts window assembly (30) and preferably at least one outwardly extending fin (77) formed thereon in contact with a wall of groove (37), (42). The seal assembly also includes a fluid filled bladder (39), (43) positioned between sealing body (36), (41) and cooperating mold section (32), (33). When increased pressure is applied to a local area of the seal as a result of a contour difference between the seal and window assembly (30), bladder (39), (43) deforms to automatically transfer at least a portion of the applied pressure to adjacent areas of the seal. Such a seal construction produces a more effective seal, produces a true gasket contour, and reduces seal fatigue, thereby increasing the life of the seal.
    • 一种独特的动态密封组件,用于模制结构,用于将玻璃窗组件(30)与垫圈(46)密封。 密封组件弹性地支撑窗户组件(30)并且与模具结构(31)协调,以限定垫圈形成腔。 模具结构(31)包括两个配合的模具部分(32),(33),每个模具部分可以设置有用于接收单独的动态密封组件的凹槽(37),(42)。 每个密封组件包括密封体(36),(41),其具有密封表面(36a),(41a),其面对并密封地接触窗组件(30),并且优选地在其上形成有至少一个形成在其上的向外延伸的翅片(77) 具有凹槽(37),(42)的壁。 密封组件还包括位于密封体(36),(41)和配合模具部分(32),(33)之间的流体填充气囊(39),(43)。 当由于密封件和窗户组件(30)之间的轮廓差异而对密封件的局部区域施加增加的压力时,气囊(39),(43)变形以将施加的压力的至少一部分自动转移到 相邻区域的密封。 这种密封结构产生更有效的密封,产生真正的垫圈轮廓,并减少密封疲劳,从而延长密封件的使用寿命。
