Referring to FIG. 10, the inner forming jig according to the present invention further includes a forming jig moving carriage 300. The forming jig 300 is used to move the inner forming jig 200 to the installation position of the inner wall surface of the refrigeration container to be installed, so that the step formed at the inlet of the refrigeration container can easily be overcome. (Not shown) capable of moving back and forth are provided on the foaming jig moving carriage so that the movement can be adjusted back and forth, and the lateral movement adjustment can be finely adjusted by a pipe (not shown) formed in the inner forming jig 200 Do.

The apparatus for forming a wall surface of a freezing container according to the present invention includes a ladder for allowing an operator to move up and down the upper surface of a freezing container for installing an outer forming jig 100 and an outer forming jig 300 for forming a freezing container .

11 to 16, a molding method using the apparatus for molding a wall of a refrigerator container according to the present invention is as follows.

Step 1 is a step of removing the wall of the freezing container damaged area (S100). First, the wall of the damaged area is removed after the freezing container damaged area is identified.

In the second step, a urethane foam injection space is provided (S200). The urethane foam is removed from the wall surface of the freezer container, and the wall is replaced with a wall surface from which the urethane foam is removed. can do.

In step 3, an outer and inner forming jig 100 and an inner forming jig 200 capable of supporting the outer and inner walls of the freezing container are installed on the outer and inner wall surfaces, respectively. When the inner forming jig 200 is moved into the freezing container, the forming jig moving carriage 300 is used. The inner forming jig 200 can be transferred from the outside to the inside through the jaw formed at the entrance of the freezing container through the forming jig moving carriage 300 to the installation position of the inner wall surface.

In step 4, the urethane foam is injected into the space between the outer wall and the inner wall formed at the upper side in the urethane foam injection step (S400) by the high-pressure foaming machine. When the urethane foam is injected into the space between the outer wall and the inner wall It becomes possible to construct a heat insulating material capable of keeping the temperature of the freezing container at a constant level.

In step 5, the outer and inner forming jig removing step S500 removes the outer forming jig 100, and the inner forming jig can be removed to the outside of the freezing container through the forming jig moving bug 300. [

Step 6 is a step of painting the wall surface of the freezing container replacement part, which is a step of painting the wall surface of the freezing container (S600).

The polyurethane foam used as the heat insulating material may be a phenol resin, a polyurethane resin, an epoxy resin, or the like. It is preferable to use an epoxy resin having a good degree of hardness after curing. Urethane foam contains polyurethane obtained by the reaction of isocyanate compound with glycols as a constituent material and volatile solvent such as carbon dioxide and freon generated by the reaction of isocyanate as a constituent and water used as a bridge- And the like. There are two types of foam molding methods, one-shot method and prepolymer process. The one-shot method is economical because it mixes the raw materials all at once and reacts them to foam, so most of the flexible foam is made by this method. The prepolymer method is a method in which a part of glycol is reacted with a diisocyanate salt in advance to prepare a prepolymer (partial polymerization agent), and the remaining glycol, a foam material, a catalyst, and the like are mixed and foamed. This method is used to create quality-conscious forms, such as rigid foam, which are used in industrial applications.

The urethane foam foamed into the space between the outer wall surface and the inner wall surface during the foaming and filling process of the urethane foam according to the conventional invention is sometimes supplied more than necessary for thermal insulation in the case of forming the heat insulating material. The space formed between the outer wall surface and the inner wall surface of a certain thickness through the forming jig provided on the wall can be maintained during the foaming and filling process so as to have a constant thickness so that the required amount of the urethane foam can be made constant, The amount of urethane foam can be reduced by fixing the wall surface through the forming jig supporting the freezing container.

In the case of repairing damage to the wall surface through the apparatus for molding a wall of the freezing container according to the present invention, one or more urethane foam injection openings (not shown) are formed on the wall surface of the freezing container and the urethane foam is injected through the urethane foam injection openings, Damage can be repaired.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims and their equivalents.
