摘要： An extrusion die for foam sheet comprises a die body defining a manifold for conducting a split stream of heated and pressurized foamable thermoplastic melt through separate distribution channels (18,20) to a die terminus. A pair of mating die lips (28,30) are arranged on opposed sides of the melt and are constructed to adjustably slide toward and away from each other to vary the flow of a melt. The lips are each mounted to slide along an axis which is tilted rearwardly at an acute angle relative to an orthogonal to the sheet being formed. The mandrel (26) is configured and adapted for quick withdrawal and replacement from an end of the die through a passageway extending through the die transverse to the direction of extrusion of a sheet.

摘要翻译：用于泡沫片材的挤出模具包括限定歧管的模具主体，用于通过分开的分配通道（18,20）将模具末端的分开的热可熔融热熔体熔体分流。一对配合的模唇（28,30）布置在熔体的相对侧上，并被构造成可相对于彼此可调节地滑动并相互偏离以改变熔体的流动。唇缘各自安装成沿着相对于正在形成的片材正交的锐角向后倾斜的轴线滑动。心轴（26）构造成适于从模具的端部通过横向于片材挤出方向延伸穿过模具的通道快速抽出和更换。
