  • Patent number: 8328546
    Abstract: An auxiliary injection unit is disclosed that has an extruder barrel and extruder screw integrated within an injection molding system. The extruder barrel and extruder screw are contained within a mold plate of the injection molding system with a drive mechanism of the auxiliary injection unit being external thereof. A melt stream emanating from the extruder barrel of the auxiliary injection unit is in selective fluid communication with either a melt channel of a manifold providing melt thereto during an injection cycle or with a discharge channel of a melt discharge tube for purging melt. A melt diverter component receives the melt stream from the extruder barrel and includes a shuttle valve slidably positioned therein that is operated to selectively divert the melt stream produced by the auxiliary injection unit to either the melt channel of the manifold or the discharge channel of the discharge tube.

  • Patent number: 8297963
    Abstract: A mold apparatus with replaceable mold plates comprises mold bases, and positioning units used to position mold plates on the respective mold bases. If the positioning units are removed, the mold plates can be easily replaced in such a manner that the mold plates are made to slide along the positioning units, facilitating the replacement of the mold plates. Since the mold plates can be quickly replaced, when different products are going to be produced, it only needs to redesign new mold plates with new forming blocks, and the new mold plates can also be applied to the original mold bases as long as they are formed with the guide grooves for cooperating with the positioning portions of the positioning units, greatly reducing the production cost while producing high economic benefits.
