泡圧がある程度低下するまで、一定時間発泡層に拘束し
てから脱型していた。Conventionally, insulating boxes such as refrigerators are manufactured by filling the space created by combining an outer box and an inner box with a fluid foam insulation material. This is done by incorporating the box into a foam layer such as a mold to prevent it from swelling under pressure. Furthermore, after filling the foam insulation material, it was held in the foam layer for a certain period of time until the foaming pressure decreased to a certain extent, and then the mold was removed.

上記従来技術は、発泡圧の減少について余シ配慮されて
おらず、脱型時間を短縮すると、外箱のふくれや内箱の
変形が生じる恐れがあった。The above-mentioned conventional technology does not take into account the reduction in foaming pressure, and if the demolding time is shortened, there is a risk that the outer box may bulge or the inner box may become deformed.
本発明の目的は、発泡断熱材充填時の発泡圧を小さくす
ることにより、外箱のふくれ等を防止し脱型時間を短縮
することができる断熱箱体を提供することにある。An object of the present invention is to provide a heat insulating box that can prevent blistering of the outer box and shorten demolding time by reducing the foaming pressure when filling the foam heat insulating material.
上記目的は、外箱と内箱とを組み合わせて形成された空
間部と、上記空間部の一部に上記発泡断熱材の発泡圧を
吸収する吸収部材を設けたことにより達成される。The above object is achieved by providing a space formed by combining an outer box and an inner box, and an absorbing member that absorbs the foaming pressure of the foam heat insulating material in a part of the space.
空間部に設けた吸収部材は、発泡断熱材を充填したとき
、その発泡圧を吸収するので１発泡圧を犬Ｉ廣に小さく
することが出来る。それによって、外箱のふくれや内箱
の変形が減少し、脱型時間を短縮することが出来る。The absorbing member provided in the space absorbs the foaming pressure when the foamed heat insulating material is filled, so that one foaming pressure can be reduced to an order of magnitude. As a result, bulging of the outer box and deformation of the inner box are reduced, and demolding time can be shortened.

る。An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. 1 is an outer box, and 2 is an inner box, each of which is restrained by an outer layer 3 and an internal layer 4. The injection port 5 is located on the top of the outer box 1.
is provided, and is equipped with an injection valve 5a. 6 is an injection machine, inject the stock solution of foam insulation material from the injection port 5, and
The structure is such that a foamed heat insulating material 7 is filled between the inner box 2 and the inner box 2.

る。In the present invention, an absorbing member (for example, maltbrene, etc.) 8 is provided in advance below the space where the outer box 1 and the inner box 2 are combined, and the stock solution of the foamed heat insulating material 7 is poured onto it. 2. The upper surface of the absorbent member 8 is surface-treated to prevent the undiluted solution from penetrating into it. When the foam insulation material 7 reaches the entire space between the outer box 1 and the inner box 2, foaming pressure is applied.
The absorbing member 8 is crushed by the pressure and at the same time moves to absorb the foaming pressure. As a result, the final product is formed as shown in FIG. According to this embodiment, the foamed heat insulating material reaches the final filling part quickly, so the density is stabilized, and the foaming pressure can be significantly reduced without impairing the physical properties of the heat insulating material. In addition, since the absorbent material is installed above the 7-lung joint between the outer box and the inner box, the foam insulation solution does not come into contact with this area, preventing the leakage of the foam insulation material. This has the effect of reducing the amount of sealant used. Furthermore, the amount of undiluted solution used can be reduced, and the foaming process can be simplified by reducing the foaming pressure.
本発明によれば、発泡断熱材充填時の発泡圧を大幅に小
さく出来るので、外箱のふくれや内箱の変形が減少し、
脱型時間の短縮がはかれ、生産性向上の効果がある。According to the present invention, since the foaming pressure when filling the foam insulation material can be significantly reduced, the bulging of the outer box and the deformation of the inner box are reduced.
It shortens demolding time and has the effect of improving productivity.
