ABSTRACT:
A mold for molding recorded discs includes a pair of mold plates, at least one of which is movable toward and away from the other mold plate and a center hole forming pin slidably mounted in an opening in one of the mold plates for movement toward and away from the other mold plate. The center hole forming pin includes an elongated rod having a passage extending longitudinally therethrough from an outer end to a closed inner end. A tube is mounted in the passage and divides the passage into an inner portion within the tube and an outer portion between the tube and the wall of the passage. A pair of tubular fittings are mounted on the rod with one fitting being connected to the inner portion of the passage and the other fitting being connected to the outer portion of the passage. A tubular sleeve cap is threaded on the closed end portion of the rod and is of a material harder than the material of the rod. The sleeve cap has a projection extending from its end which forms with the closed end of the rod a recess with the closed end of the rod being the bottom of the recess.
