Apparatus for producing a molded article with a recess therein including an elongated tapered core which is mounted for limited axial shifting relative to parts which form sides of a mold. The core is adapted to be shifted between one position which it occupies during molding of an article, and another (partially retracted) position wherein it is free from an article in the mold. Movement of a pallet to a position forming one of the sides of the mold shifts the core toward the first position mentioned. A ram carrying an element which is releasably engageable from the core may be operated to shift the core toward the other position.
