摘要： A mold bushing for injecting plastic material into a mold cavity. The bushing member has a one-piece body member with a central passageway for a shut-off gate pin member and a separate and distinct passageway for the molten plastic material. In one embodiment, a tip member is positioned on the end of the body member and has a material discharge chamber. A gate or orifice opened and closed by the pin member is positioned either in the tip member or the mold. A wear bushing member can be positioned in the discharge chamber or the end of the body member to support the end of the pin member and prevent the flow of plastic material into the central passageway. The body member is heated by an annular cast heater member or the like. In an alternate embodiment, the body member has an extension which partially fills the discharge chamber and the wear bushing is a cylindrical member positioned at the discharge end of the central passageway. In another alternate embodiment, an insert member is positioned on the lower end of the body member and held in place by a threaded sleeve member. The insert member has a first channel in alignment with the central passageway in the body member and a second channel in alignment with the molten plastic passageway. The first and second channels converge in an orifice whose opening is controlled by movement of the pin member.

The body member is heated by an annular cast heater member or the like. The wear bushing member can be indexed for proper positioning relative to the body member and the plastic flow passageway. The wear bushing member preferably has a body portion which partially fills the discharge chamber in the tip member. In an alternate embodiment, the body member has an extension which partially fills the discharge chamber and the wear bushing is a cylindrical member positioned at the discharge end of the central passageway.
