ABSTRACT:
An injection mold assembly including a plurality of mold dies supported for relative movement between a mold open position and a mold closed position, each of the mold dies including a molding surface adapted to form a portion of the surface of a molded article. The mold assembly also includes a plurality of core pins for forming holes in the molded article. At least part of each of the core pins is made of a resilient, non-metallic material. The core pins are supported on one of the mold dies and are engageable with an opposed mold surface when the mold assembly is closed, such engagement resulting in the elastic deformation of the non-metallic part of the mold core pins.
