  • Publication number: 20080042310
    Abstract: A magnetic mold closure system [1000] employs at least two mold parts [1110, 1120] having at least one solenoid (1300, 1400). A bidirectional power controller [1500] provides current to a plurality of electromagnetic solenoids [1300, 1400] to precisely hold the mold parts [1110, 1120] together. This attraction effectively automates the closing of the mold closure, so as to begin the casting process. Upon curing of the material to a point where it can be removed from the mold parts [1110, 1120], a logic unit [1200] determines when to open the mold closure [1100]. The bidirectional power controller [1500] applies current in a reverse direction to provide a repelling force which automates the opening of the mold closure [1100]. This automated approach to the molding will reduce cycle times and waste while providing a more ergonomic and safe environment for the operator of the mold closure.

  • Patent number: 7114936
    Abstract: In the method, after the pattern-bearing film is fed to the female mold, the distal end of the film is fixed under a lower portion of the female mold, and at the same time the film is retreated by a force from the film supply portion. Thus, this tightens up the film so that the slacks or wrinkles cannot be formed on the film. Therefore, the film can be fortunately spread around the parting surface of the female mold. In the apparatus, the film suppressing frame is pressed to the female mold through the sliding rod arranged in the female mold, in such a manner that the female mold embraces the frame. Thus, the pressing of the frame is performed by a simple structure, and the film is accurately positioned to the internal surface of the female mold. Also, the film suppressing frame is constituted to advance from and retreat to the female mold. Thus, this causes a space between the both molds and an outside standby position to be useless. A space around the apparatus can be effectively utilized.

    Abstract: The invention provides a blowing agent delivery system for introducing a blowing agent into a polymeric foam processing system. The delivery system is designed to discontinuously introduce blowing agent from a continuous source into polymeric material within an extruder. The system, thus, may improve control over blowing agent delivery in discontinuous polymer processing systems such as injection molding or blow molding. In some embodiments, the blowing agent delivery system selectively directs blowing agent flow from the source to the extruder barrel, or through a bypassing passageway. In this manner, blowing agent may be continuously supplied by the source but discontinuously injected into the extruder barrel. During use, the delivery system may cause blowing agent to flow through the bypassing passageway, for example, when the screw stops plasticating polymeric material.

  • Patent number: 6851907
    Abstract: A binding machine and method for spirally binding a sheaf of papers into a book uses an adjustable speed drive to rotate a flexible plastic spiral element into respective holes in the book. The book has a plurality of holes in a row adjacent one edge of the book to receive the leading edge of the spiral bonding elements. A cylindrically shaped mandrel is spaced apart from a glidable block. The plastic pre-formed spiral binding element is fed onto the mandrel from the distal end thereof, with the leading edge of the binding element facing and spaced apart from the book. A pair of leading edge spreaders, one of which has a guidance groove, engages the plastic spiral to spread its coils just enough to permit it to enter the successive holes of a sheaf to be bound. A trailing spreader at the opposite end insures that the last hole is accommodated with a portion of the spiral coil.
