Abstract:
1. A plastic injection molder comprising: a base; two frame rails connected to the base, and extending vertically; an upper support extending horizontally between the frame rails, and rigidly connected to the frame rails; an injection actuator positioned between the upper support and an injection piston, and capable to exert force on the injection piston; the injection piston positioned between the frame rails, and movably connected to the frame rails, and inserted into a barrel at least partially; the barrel comprising an opening and an aperture, and positioned between the frame rails and below the injection actuator; the aperture of the barrel formed on the side of the barrel, and is in communication with the opening of the barrel; an upper clamp member comprising an opening and a channel, and extending horizontally between the frame rails, and rigidly connected to the frame rails, and positioned below the barrel; the opening of the upper clamp member is in communication with the opening of the barrel; the channel of the upper clamp member is an open C channel having a flat portion and reinforcing ridges connected to the flat portion; a lower clamp member extending horizontally between the frame rails, and movably connected to the frame rails, and positioned below the upper clamp member; the upper clamp member and the lower clamp member capable of securing an injection mold therebetween; a clamp actuator positioned between a lower support and the lower clamp member, and capable of exerting force on the lower clamp member; the lower support extending horizontally between the frame rails, and rigidly connected to the frame rails.
