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.
And the arrangement for the die transferring mechanism on the molding apparatus permits a provision of the molding apparatus away from a passage for the carriage because the die is conveyed into or from the molding apparatus by its own die transferring mechanism. This also causes no problem with making the molding apparatus a larger size and provides a wide space around the molding apparatus for the maintenance area.
