摘要： An extrusion die assembly is provided for making honeycomb structures of ceramics, glass, and other extrudable materials. The assembly is provided with an apertured, flow controlling forming plate (44) placed against the input (upstream) surface of the extrusion die (12). The forming plate has a central opening (50) through which the batch material to the input face of the die passes. A series of angularly spaced, flow controlling openings (46) lies radially outwardly of the rim of this central opening. These forming plate openings are axially aligned with a shim reservoir (30) downstream of the discharge slots of the die. This arrangement permits both the flow volume and rate of the batch material being extruded to the skin forming portions of the die assembly to be at least partially independently controlled relative to the flow volume to the main, radially central portion of the extrudate. By this construction, the formation of air checks in the shim reservoir and the formation of rippled skin on the extrudate is inhibited.

摘要翻译：提供了用于制造陶瓷，玻璃和其它可挤出材料的蜂窝结构的挤出模头组件。该组件设置有抵靠挤出模具（12）的输入（上游）表面放置的有孔流动控制形成板（44）。成形板具有中心开口（50），批量材料通过该中心开口通过模具的输入面。一系列角度间隔开的流动控制开口（46）位于该中心开口的边缘的径向外侧。这些成形板开口与模具的排放槽下游的垫片储存器（30）轴向对准。这种布置允许将批量材料的流量和压缩率相对于挤出物的主要径向中心部分的流动体积至少部分地独立地被控制地挤出到模具组件的皮肤形成部分。通过这种结构，抑制了垫片储存器中的空气检查的形成和挤出物上的波纹皮肤的形成。
