ABSTRACT:
An injection molding machine includes a stationary platen including at least one stationary mold half and a first movable platen. The first movable platen is movable relative the stationary platen and has a second mold half adapted to engage the stationary mold half to form a first mold. A second movable platen may also be provided which is movable toward the stationary platen and includes a third mold half adapted to engage a fourth mold half included with one of the stationary platen and the first movable platen. The third and fourth mold halves form a second mold. Each of the first and second molds having a hot runner leading thereto and an injection unit is provided for delivering melt to the hot runners of the first and second molds. The machine further includes tie bars extending between and connecting the stationary platen and the movable platens. At least one of the first and, if used, the second movable platen and stationary platen includes a mechanism for securing at least one of the tie bars. The mechanism for securing comprises an engagement mechanism for placing the mechanism for securing into and out of locking engagement with at least one of the tie bars such that when the engagement mechanism is out of locking engagement with the at least one tie bar, the mechanism for securing and the at least one tie bar are relatively movable.
