Abstract
A combination rubber injection gate system ( ) and method of injection molding rubber to produce desired flow patterns in the rubber is disclosed. The combination gate ( ) directs rubber through a first region ( ) to flow at cross angles ( ) through the injection gate ( ), relative to the direction of flow of the rubber ( ) through the injection gate ( ). The rubber ( ) is then directed through an adjacent region ( ) to flow through the injection gate ( ) at a direction parallel to the direction of flow of the rubber ( ) through the entire injection gate ( ). The combination gate ( ) yields a highly mixed and uniform flow of rubber ( ) that is particularly useful when injection molding fiber-loaded rubber where it is desired to orient the fibers in a particular direction.
