The mold half assemblies are configured to cooperatively form the exterior shape of the necks of a plurality of parisons. Heat transfer channels formed in both the die sets and the mold half assemblies are fluidly connected with each other, such that a heat transfer fluid can be routed to the mold half assemblies via the die sets.

  • Patent number: 8512625
    Abstract: An injection blow molding (IBM) system and method for controlling the surface temperature of the parison molds by passing heat transfer fluid through a plurality of fluidly-coupled heat transfer channels. The heat transfer channels can be formed primarily in die sets to which the parison molds are attached. The placement and distribution of the heat transfer channels relative to the parison-forming surfaces helps control the temperatures of the bodies and necks of the parisons being formed, instead of relying on various adjustments by an IBM operator. This system/method reduces the discretion required by the IBM operator and shifts the burden of consistently making high-quality parisons and molded articles onto the designer of the IBM tooling.

    Abstract: A technique for allowing the convenient and orderly withdrawal of contents is disclosed. An apparatus according to the technique may include a container which includes an enhancement at the rim of the container. The enhancement provides the functionality to move edible and/or inedible substances onto objects. In one example, the enhancement may protrude inwardly as a smoothed surface that may push substances onto objects as the objects are removed from the container.

  • Patent number: 8454347
    Abstract: A sprue device for an injection mold includes a first part and a second part. The sprue device is sealed and water-cooled so as to reduce overall molding time. The connecting section defines spiral grooves. The second part includes a chassis and an extension from the chassis. The chassis is defined with a through hole, and two gates communicated with the through hole respectively. The spiral grooves mate with the wall of the mounting hole to form a spiral runner. The gates, the through hole, and the spiral runner communicate with each other. An injection mold using the sprue device is also described.

  • Publication number: 20130071511
    Abstract: A method of producing at least one conformal cooling passage in a part-producing mold, and a mold provided with such a conformal cooling passage(s). A conformal cooling passage is produced by creating an open channel in a molding surface of a mold of interest, the channel substantially conforming to the contour of the molding surface. A bridging weld formed from a plurality of connected weld beads is generated in the channel so as to span and seal the channel while enclosing an open passage in the bottom thereof. The remainder of the channel above its bridging weld is filled, such as by welding, and an exposed portion of the fill material in the channel may be subsequently shaped to conform with the contours of the molding surface surrounding the channel. A sub-surface conformal cooling passage is thus formed in the mold.
