ABSTRACT:
Injection molding apparatus having a number of side gate seals extending outwardly from a heated central nozzle to convey melt to cavities spaced around the nozzle. Each side gate seal has an inner end seated in a front portion of the nozzle and extends outwardly across an insulative air space into a radial opening in a cooled mold leading to a gate to a respective cavity. Each side gate seal has a pointed tip in alignment with the gate and a cylindrical sealing rim which fits in a matching cylindrical portion of the radial opening in the mold. This seal around the side gate seal locates the nozzle longitudinally while allowing the cylindrical sealing rim to slide slightly inwardly and outwardly to allow for thermal expansion and contraction of the side gate seal.
