ABSTRACT:
A mold for use in a gas-assisted injection molding system includes a gas pin assembly which can be readily removed from one mold half in an open position of a mold wherein a porous insert of the assembly can also be readily removed from the housing of the assembly for easy servicing. The housing of the assembly has an elongated aperture formed therethrough in communication with a gas passageway in the mold to permit the flow of gas therethrough. The porous insert is positioned in the aperture. The insert permits the flow of gas therethrough but prevents the passage of molten plastic therethrough. The assembly also includes a holding device preferably in the form of a set screw which has a gas hole formed completely therethrough to permit the flow of gas therethrough. The set screw is threadedly secured within the housing to hold the insert stationary within the aperture and to permit ready removal of the insert from the housing after the set screw has been removed from the housing.
