Abstract

PURPOSE:To reduce the cost of a door and to improve its productivity by commonly using a foam suppressing jig for manufacture of various heat insulation doors. CONSTITUTION:An outer shell is formed by mounting a gasket holder 15 to be mounted with a gasket 17 and a rear surface plate 16 swelled to a rear surface side on a rear surface of a door panel 14. Sizes are so set that the gasket 17 and the plate 16 are disposed substantially in plane in a state that the gasket 17 is elastically compressed to be deformed. In order to fill urethane foam, the shell in which the gasket 17 is previously mounted is contained in a receiving jig 19, pressed by a pressing jig 20, and urethane stock solution is poured. In this case, a pressing surface of the jig 20 is formed in a flat surface state, and foaming pressure to be operated at the holder 15 is received by the jig 20 via the deformed gasket 17.

[Function] When filling the outer shell with the foamed heat insulating material, a gasket is attached to the outer shell in advance, and the gasket is elastically compressed and deformed so as to be held by the holding jig. It becomes possible to receive the bubbling pressure of the above with a pressing jig through the gasket. According to the heat insulating door of the present invention, since the gasket is elastically compressed and deformed from the back surface side, the size of the gasket is set so that the front end of the gasket is substantially flush with the back surface of the outer shell. It is possible to press the back surface side of the outer shell by using a pressing jig having a flat surface. Further, according to the method of manufacturing the heat insulating door of the present invention, the gasket is attached to the outer shell body in advance, and the pressing surface of the holding jig is formed into a flat plate shape, and the gasket is attached to the outer shell body by the holding jig. Since the undiluted solution of the foam insulation material is foamed while being elastically compressed and deformed so that it is almost flush with the back surface, even if the peripheral portion of the outer shell to which the gasket is attached has a thin shape, it is pressed. The pressing jig having a flat surface can receive the foaming pressure through the gasket.

As described above, the outer shell body 12 is housed in the foaming jig with the gasket 17 previously attached to the gasket holder 15. At this time, since the pressing surface of the pressing jig 20 is flat, the gasket 17 is elastically compressed and deformed from above as shown in FIG.
The upper surface of the back plate 16 is pressed so as to be substantially flush with the back plate 16. In this state, a required amount of the undiluted urethane solution is injected into the outer shell body 12 from the unillustrated injection port of the back plate 16, and the undiluted solution is foamed to fill the urethane foam 13 inside. After the urethane foam 13 is hardened, the pressing jig 20 is opened, and the outer shell 12
The (heat insulating door 11) is taken out from the receiving jig 19.

When urethane foams, a considerable foaming pressure acts on the outer shell 12 from the inside, but the foaming pressure acting on the door panel 14 is received by the receiving jig 19 and the back plate 16 is exposed. The acting foaming pressure is received by the pressing jig 20. The foaming pressure acting on the gasket holder 15 is elastically compressed and deformed in the gasket 1.
It can be received by the pressing jig 20 via the gasket 7, so that the urethane can be foamed without the gasket holder 15 coming off or deforming. As described above, according to this embodiment, the gasket 17 is dimensioned so that the back surface of the gasket 17 is substantially flush with the back plate 16 in a state where the gasket 17 is elastically compressed and deformed from the back surface side. Even if there is a predetermined step difference between the gasket holder 15 and the back plate 16, the foaming pressure acting on the gasket holder 15 is applied to the gasket 17 by the foaming jig (pressing jig 20) having a flat pressing surface. Can be received through.

Therefore, unlike the conventional one in which a separate pressing jig having a shape that follows the shape of the step formed by the back plate 4 and the gasket holder 3 is required for each product type, the pressing surface is flat. Since the same pressing jig 20 described above can be used, the pressing jig 20 can be commonly used for each type of heat insulating door 11. As a result, the holding jig 2
It is not necessary to newly manufacture or replace 0 for each product type, and it is possible to reduce costs and improve productivity. FIG. 4 shows another embodiment of the present invention. The difference from the above embodiment is that a seal member 31 for preventing urethane from leaking during foaming is provided on the inner surface of the gasket holder 15. is there.

In this case, conventionally, it was necessary to carefully seal a wide range of seals for preventing urethane from leaking during foaming, but in the present embodiment, the gasket holder 15 is previously prepared.
Since the gasket 17 is attached to the
There is no risk that urethane will leak into the mounting recess 15b of the gasket holder 15 and solidify, and this will hinder the mounting of the gasket 17. Therefore, it is sufficient to provide the sealing material 31 in a narrower area than in the conventional case, and it is possible to obtain the effect of simplifying the work. The present invention is not limited to the above-described embodiments, and can be applied to, for example, a stocker, a hot storage, etc. as well as a refrigerator, with various modifications without departing from the scope of the invention.
