Abstract

PURPOSE: To prevent a formed matter from being deformed by the heat of reaction of urethan by providing a device cooling only the necessary part of a metal mold for the foamed forming of polyurethan.
CONSTITUTION: On the preparation of a heat-insulating box by filling polyurethan form between an outer box 1 and an inner box 2, a cooling device is provided for cooling only the necessary part of a metal mold 3 used for fitting the outer and inner boxes 1 and 2 and preventing the part of thin plate of the inner box 2 from being softened and deformed, by absorbing the heat of reaction of urethan. As a concrete example for such a cooling device, there is a device wherein a piping 4 is provided in the region of the metal mold 3 corresponding to the part of thin plate of the inner box 2 and a heat medium such as water is contained and circulated.
