An elongate threaded rod member comprises a central portion, and two oppositely extending outer portions. The central portion is attached to the periphery of the first plate, is rotatable with respect to the first plate and is prevented from axial movement relative thereto. Each outer portion includes a threaded portion with each having the same threading pitch and density but being in opposite orientation. A threaded connector is secured to the periphery of each second plate with each threaded portion in screw-threaded relation. The threaded portions rotate within each bore an equal an opposite amount, equalizing the distances of each second mold plate from the first mold plate as the apparatus is moved between open and closed positions. At least one outer portion is releasably detachable from the central portion, thereby allowing at least one second mold plate to be separated from the first plate along the mold axis beyond the open position and beyond the length of the threaded portions without the threaded connector losing threaded engagement with the threaded rod portion.
