ABSTRACT:
A mold for making articles that are interconnected by a lanyard, such as inflator parts. A mold base has a channel formed in it, and a first block is slidably mounted in that channel. A groove formed in the block defines the contour of a first article produced by the mold when plastic is injected into the groove and a mating groove formed in a mold cover that overlies the base. A stationary second block, also disposed in the channel, has a cavity formed in it that defines the contour of a second article. Opposite ends of the lanyard are positioned in the respective areas bounded by the grooves and cavity so that the opposite ends of the lanyard are embedded in the articles produced by the mold. The length of the interconnecting lanyard is adjusted by adjusting the position of the moveable block within the channel. The movable block may also be stationery.
