(Prior Art) A refrigerator door is provided with a heat insulation effect by a rigid urethane foam, but an external force is applied to this door. In particular, since the refrigerator compartment door has a pocket on the inner surface and food or the like is stored in this pocket, a large twisting force is applied.
Therefore, it is necessary to give the refrigerator door sufficient rigidity. Therefore, conventionally, an iron reinforcing plate having rigidity is arranged so as to be passed over the upper surface flange of the container-shaped door body,
After fixing the reinforcing plate to the flange by screwing, urethane was injected and foamed in the door body to fill it. Thereby, a high-strength refrigerator door having rigidity can be obtained.

(Problems to be solved by the invention) When the above-mentioned conventional method is used, it is necessary to perform machining to form screw holes in the reinforcing plate and the door body, resulting in a large number of man-hours such as drilling and degreasing, and cost. There was a problem of being up. The present invention has been made in view of the above circumstances, and manufactures a rigid high-strength refrigerator door including a reinforcing plate without performing machining for fixing the reinforcing plate. The purpose is to provide a method.

(Operation) According to the present invention, when the reinforcing paper temporarily closes the lower surface of the sealing paper to close the opening of the upper surface of the door body, and the sealing paper is pressed and deformed downward by the foaming jig, Since it has rigidity, it is temporarily fixed to the sticker paper and is separated from the sticker paper by its own weight. Therefore,
A space is formed between the reinforcing paper and the seal paper at the peripheral edge of the reinforcing plate, and the urethane foam is filled with hard urethane foam, and the rigid urethane foam adheres to the upper and lower peripheral edges of the reinforcing plate. As a result, the reinforcing plate having rigidity is automatically embedded and held in the rigid urethane foam.

The container-shaped door body 9 may be integrally formed, but in the present embodiment, it is composed of a bending door 10 and a winding sash 12. Bending door 10
Is manufactured by bending four edges of a metal plate or the like into a U-shape, and the opening is directed upward, and the winding sash 12 is fitted into the edge 11. The rolled sash 12 is manufactured in a frame shape by extrusion molding, its sectional shape is basically L-shaped, and the locking claw 13 is provided at the tip of the inwardly extending portion thereof. U-shaped peripheral part of bending door 10
I try to fit it in 11. The winding sash 12 thus has the locking claws 13 that support the bending door 10 from the inside, and also has the protruding external support portion 14 that supports the bending door 10 from the outside so that the winding sash 12 can be engaged with the bending door 10. I have to. Also,
The inwardly extending portion of the winding sash 12 has a packing supporting portion 15 for inserting a packing, and a flange 16 extending inward from the packing supporting portion 15 in parallel with the bending door 10. This flange 16
The area of the rectangular opening is smaller than that of the sticker paper 2.

After injecting urethane from the hole 4 provided in the sticker paper 2, the injected urethane is foamed while sandwiching this door from above and below by the foaming jigs 22 and 24. Upper foam jig 22
A projecting portion 23 is formed downward in the center of the projecting portion 23, and the projecting portion 23 is pressed against the seal paper 2 from above the reinforcing plate 6. It should be noted that one width of the tip end plane of the protruding portion 23 is formed smaller than the width of the reinforcing plate 6. The lower foaming jig 24 supports the door from below so as to wrap the bending door 10 and the winding sash 12. At this time, the sticker paper 2
Is pressed and deformed downward by the protruding portion 23 of the foaming jig 22 on the upper side, and the reinforcing plate 6 temporarily fixed to the lower surface of the seal paper 2 has rigidity so that the adhesive tape 8
The temporary fixing to the sticker paper 2 due to is removed, and the sticker paper 2 is separated from the sticker paper 2 by its own weight. Then, a large space is formed between the reinforcing paper 6 and the seal paper 2 at the peripheral edge 7, and when foaming proceeds, the internal space of the door including this space is filled with the hard urethane foam 28. Therefore, the rigid urethane foam 28 is in close contact with the peripheral edge 7 of the reinforcing plate 6 having rigidity, and the peripheral edge 7 is automatically embedded and held in the rigid urethane foam 28. Also,. Rigid urethane foam for inner surfaces of sticker paper 2, bending door 10 and winding sash 12
Since 28 is in close contact, the reinforcing plate 6 and these members are firmly bonded to each other. If the foaming jigs 22 and 24 are removed from this state, a high-strength refrigerating compartment door having rigidity can be obtained.
