Abstract

A plastics molding device is disclosed, which provides a plurality of cavities for the simultaneous molding of a plurality of flash caps, and including a punch die, operably supported relative to an outer end of each flash cap cavity, to punch a disc shaped member from a sheet of an appropriate synthetic material, and to position each disc in one of the cavities, in a proper position, to define integral outer end walls in the flash caps, when a suitable molten plastic material is injected into the respective cavities by way of appropriate runner grooves, in a generally conventional manner. Prior to injecting the plastic material, a core pin is advanced into each cavity in a simultaneous relation to the operation of the punch die, to clamp the respective disc members in outer ends of the cavities.
