  • Patent number: 8066507
    Abstract: A rotary plate is rotatably supported with respect to a stationary base using an R-guide, and the weight of the rotary plate and a mold mounted to the rotary plate is also supported by the R-guide in addition to a bearing. Therefore, a moment and a vertical downward load acting on the bearing of the rotary plate can be reduced. A block of the R-guide is fixed with respect to the rotary plate side through a disc spring. Therefore, while the rotary plate is rotating, the elastic force of the disc spring causes the rotary plate to separate from the stationary base by a space, which reduces the rotational resistance of the rotary plate. During mold clamping, respective pressure-receiving surfaces of the rotary plate and the stationary base contact each other against the elastic force of the disc spring, which enables reliable transfer of a mold clamping load to the stationary base.

  • Patent number: 7645135
    Abstract: This invention relates to methods and apparatus for making articles made of polyester, preferably polyethylene terephthalate (PET), having coated directly to at least one of the surfaces thereof one or more layers of thermoplastic material with good gas-barrier characteristics. In one preferred method and apparatus, preforms are injection molded, barrier-coated immediately thereafter, and remain on a mold portion for a time to speed cooling of the completed preform. Preferably the barrier-coated articles take the form of preforms coated by at least one layer of barrier material and the containers are blow-molded therefrom. Such barrier-coated containers are preferably of the type to hold beverages such as soft drinks, beer or juice. The preferred barrier materials have a lower permeability to oxygen and carbon dioxide than PET as well as key physical properties similar to PET.

  • Patent number: 7497676
    Abstract: A procedure for sequential molding of an assembled object and a machine for the performance of the procedure are provided. A mold has a stationary front part, a movable back part and at least one turnable middle part. After the molding of the first part of an object, the middle part is turned at least once around an axis orthogonal to the moving direction between the front part and the back part, before the molding of the following part of the object takes place. Injection and cooling can take place in the front part and in the back at the same time. In an alternative embodiment, the middle part can be fitted with insulation to maintain a higher temperature between different regions of the mold assembly, making it possible to mold together considerably different materials such as a thermo plastic material and an elastomer, a silicone, or metal and plastic.

    Abstract: The invention concerns machinery for molding and assembling of at least two part objects and of plastics, e.g. two ball shells, which can be assembled to a hollow ball, as molding and assembly can take place in the same tool and continuously in the same work procedure. This can be realized by the two turnable middle parts and of the tool, respectively are supplied with the mold cavities and, where the assembling of the part objects and can take place, when the respective tool cavities meet during the rotation, at the same time as the closing of the mold. During the closing there can simultaneously be molded new part objects and in the opposite placed mold cavities and in the two turnable mold part and. If it is necessary in respect of the material or the design of the part objects, there can after the molding of the part objects be applied e.g. heat on the respective boundary surfaces, which shall shape the assembling. This can suitably be fit into the steps, which the turnable middle parts and run through.
