Abstract: A mold for an injection molding tool. The mold has a pin gate extending between a gate inlet and a gate opening. The pin gate forms a tapered, cylindrical channel through a body of the mold and abruptly transitions to a smooth funnel. The gate opening is positioned at an end of the funnel. The pin gate is configured to receive molding material from a runner channel of the injection molding tool at the gate inlet and dispense the molding material at the gate opening. The mold also has a mold cavity in fluid connection with the gate opening of the pin gate and configured to receive the molding material therefrom.

Abstract: A mold insert having a main body including a first surface and an opposed second surface, the first surface defining a plane. The mold insert also has a mold core extending from the first surface and a gas inlet port connectable to a supply of pressurized gas. Further, the mold insert has two or more gas outlet ports arranged to direct a gas flow towards an uncovered surface of an injection molded item located on the mold core, after the mold core and the mold cavity are separated from each other. Further, the mold insert has a gas conduit system extending inside the main body connecting the two or more gas outlet ports with the gas inlet port. Each of the two or more gas outlet ports are arranged through the first surface. The gas conduit system is provided in the main body below the first surface.
