摘要： In a heat displacing type die adapted to extrude a sheet of molten resin, a heat displacing unit (51) provided with a heater (54) is secured to an upper die block (11). A lip gap (15) is defined between a flexible lip (13) and a stationary lip (14) respectively provided for the upper and lower die blocks. The lower end of a bolt extending through the heat displacing unit (51) is normally in contact with or secured to the flexible lip (13) while the upper end is secured to the upper portion of the heat displacing unit (51). In a modified embodiment the bolt is air cooled. With this die a resin sheet having uniform thickness and smooth surface can be obtained.

摘要翻译： 在适于挤出熔融树脂片的换热型模具中，设置有加热器（54）的散热单元（51）固定到上模块（11）。 唇间隙（15）被限定在分别为上模块和下模块提供的柔性唇缘（13）和固定唇缘（14）之间。 延伸穿过热移动单元（51）的螺栓的下端通常与柔性唇缘（13）接触或固定，同时上端固定到换热单元（51）的上部。 在改进的实施例中，螺栓是空气冷却的。 通过该模具，可以获得具有均匀的厚度和光滑表面的树脂片。
