  • Patent number: 4993933
    Abstract: The molding installation includes a molding area where a molding apparatus for effecting the molding with a die is disposed; a maintenance area adapted to subject the die to maintenance work and disposed adjacent to the molding area; a die position shifting apparatus adapted to shift a position of the die and disposed between the molding area and the maintenance area; and a carriage adapted to exchange the die for another in the molding apparatus and disposed on a passage connecting between the molding apparatus and the die position shifting apparatus.The die position shifting apparatus is designed capable of shifting a die position of the die to the die position required in the molding area or in the maintenance area without any labor of workers.This arrangement in the molding installation permits a full automation of a series of operations including the die exchanging operation, the die conveyance operation for conveying the die into or from the molding apparatus and the die position shifting operation.

  • Patent number: 4880792
    Abstract: The molding installation includes a molding apparatus adapted to effect the molding with a die; a stocker adapted to store the die; a carriage having a table with the die loaded thereon, the stocker being adapted to exchange the die for another in the molding apparatus and disposed on a passage connecting between the molding apparatus and the stocker; a die transferring mechanism mounted on the molding apparatus and adapted to transfer the die between the molding apparatus and the carriage; and another die transferring mechanism mounted on the carriage and adapted to transfer the die between the carriage and the stocker.The arrangement for the die transferring mechanism on the carriage avoids a provision of a die transferring mechanism on each stocker, thus making the die transferring mechanism on the carriage a smaller size, reducing an inertia thereof, leading to a speed-up of operation thereby, enabling a rapid suspension thereof and rendering a molding cycle more efficient.
