    摘要： Method for tri-injecting a plurality of thermoplastic materials to mold an article having a layered wall structure using thermoplastic materials having different optimum processing temperatures including the maintenance of the optimum temperatures in flow paths individual to each material from its source at least to the injection nozzle. At least two of the nozzle channels are insulated to prevent heat transfer and to maintain the temperature of the thermoplastic materials.

    摘要： An injection mold with a female mold portion and a male mold portion has a locking ring which closely surrounds one mold portion and has a beveled inner centering surface coacting in a mold-closed position with a complementarily beveled outer centering surface of the other mold portion for properly aligning the two mold portions with each other. The locking ring and the mold portion surrounded thereby form an assembly mounted on a backing plate by means of bolts screwed into that assembly, the bolts having heads bearing upon spacing sleeves which abut the assembly and are received with some clearance in a bore of the backing plate. The sleeves project from the bores of the backing plate to provide room for one or more Belleville springs acting upon the bolt heads to keep the sleeves under pressure. The bolts, sleeves and springs, being thus rigidified with the assembly of mold portion and locking ring, are slightly shiftable relatively to the backing plate within the clearance of their bores for automatically compensating disalignments due for example to thermal causes. The locking ring may be separable from the associated mold portion in a mold-open position to entrain a stripper ring coupled therewith; otherwise the stripper ring may be movable relatively to the assembly by actuating rods traversing the backing plate. The locking ring may be replaced by wedge pieces.
