    • A combination rubber injection gate system (24) and method of injection molding rubber to produce desired flow patterns in the rubber is disclosed. The combination gate (24) directs rubber through a first region (26) to flow at cross angles (38, 40) through the injection gate (24), relative to the direction of flow of the rubber (22) through the injection gate (24). The rubber (22) is then directed through an adjacent region (28) to flow through the injection gate (24) at a direction parallel to the direction of flow of the rubber (22) through the entire injection gate (24). The combination gate (24) yields a highly mixed and uniform flow of rubber (22) that is particularly useful when injection molding fiber-loaded rubber where it is desired to orient the fibers in a particular direction.
    • 公开了一种组合橡胶注射门系统(24)和注射橡胶的方法以在橡胶中产生所需的流动模式。 组合门24引导橡胶穿过第一区域26相对于橡胶(22)通过喷射门(22)的流动方向通过喷射浇口(24)以交叉角(38,40)流动 24)。 然后,橡胶(22)被引导通过相邻区域(28),以通过整个喷射门(24)沿与橡胶(22)的流动方向平行的方向流过喷射门(24)。 组合门(24)产生高度混合且均匀的橡胶流动(22),当注射成型纤维负载的橡胶时,其需要在特定方向上定向纤维时特别有用。
