    • An extrusion molding apparatus capable of improving the extrusion rate of the ceramic material without a major reconstruction of a drive system is disclosed. The extrusion molding apparatus comprises screw extruders (2, 3) including housings (29, 39) having screws (4, 5) built therein, wherein the ceramic material introduced into the housings (29, 39), respectively, is extruded by way of the forward end extrusion ports by rotating the screws (4, 5). The screws (4, 5) built in the screw extruders (2, 3), respectively, include pressure portions (41, 51) with the feed rate per revolution progressively decreased toward the forward end extrusion port, and extended portions (43, 53) with the feed rate per revolution progressively increased toward the forward end extrusion port.
    • 公开了一种能够改善陶瓷材料的挤出速率而不需要重大驱动系统的挤出成型设备。 挤出成型装置包括螺旋挤出机(2,3),其包括内置有螺钉(4,5)的壳体(29,39),其中分别引入壳体(29,39)中的陶瓷材料被挤出通过 通过旋转螺钉(4,5)来驱动前端挤压端口。 螺杆挤出机(2,3)中内置的螺杆(4,5)分别包括压力部分(41,51),每转的进料速度朝向前端挤出口逐渐减小,并且延伸部分(43,43) ),每转的进料速率朝向前端挤出口逐渐增加。
