ABSTRACT:
A quick die change device for use in foaming of insulation for refrigerator cabinets comprising a bottom die suitable for working together with an upper die plate bearing a plurality of dies for obtaining the insulation. The size of the insulation changes as the dimensions of the refrigerator cabinets change. The dies are placed in such a way as to work together with the bottom die by rotating the die plate around a minor axis. The rotation is obtained by a gear motor, a number of belts and a shaft coinciding with the minor axis of the plate.
