A method and apparatus for producing an extruded product includes a machine that cooperates with an extruder. The machine is commonly used as a corrugator and the extruded product is often corrugated piping. The machine has a frame supporting a trackway in a continuous path. A plurality of mold block assemblies travel about the continuous path to form a mold tunnel along a portion of the continuous path. The mold block assemblies include a carriage connected by at least one guide and linear bearings to a pair of mold holders. The mold holders are connected to at least one pair of opposing mold blocks. Guides and directors position the mold block pairs relative to one another while the assemblies travel along the continuous path. As the holders, and thus the mold block halves, are linearly displaceable from one another, the halves may meet to form the mold tunnel and separate to allow removal of the extruded product.
A machine cooperable with an extruder to continuously mold an extrudable material comprising:
The machine cooperable with an extruder to continuously mold a product comprising:
A mold block assembly in combination with an extruder and a machine with plurality of mold block assemblies operated in a continuous loop along a track, said track having at least two curved segments, each of said mold block assemblies following the track and an adjacent mold block assembly, each of said mold block assemblies comprising:
A method for producing an extruded product utilizing a machine having a continuous trackway configured in a continuous path, a frame supporting the trackway, a plurality of separate mold block assemblies restrained to travel about said trackway, and at least one pair of mold block halves connected to each of said plurality of mold block assemblies, said mold block halves linearly displaceable from one another and capable of mating engagement to form a mold tunnel therein, said method comprising the steps of:
