In order to achieve the above object, a foaming apparatus for a heat insulating cabinet according to the present invention has a main body composed of a frame and a lowering position for carrying in and carrying out the cabinet, and is carried into the inside of the main body. Table movable to an ascending position that cooperates with an inner jig that can come into contact with the inner wall of the cabinet, a pair of sliding frames on the left and right of the inner jig that are laterally slidable, and both outer wall surfaces of the cabinet A pair of side plates that are in contact with each other and whose upper side is pivotally supported by the sliding frame, a plurality of link mechanisms that connect the lower part of the sliding frame and the lower side of the side plate to open the side plates, and the sliding frame with respect to each other. It is composed of left and right screws that are provided in the perspective direction. Also, a positioning frame provided near the center of the upper portion of the inner jig and provided with a positioning pin, a sandwiching member provided so as to face the upper surface of the sliding frame, and a base for holding the inner jig. The base is provided with a positioning hole for mating with the positioning pin, and a pair of mating rails provided on the upper surface of the base and mating with the pinching member when the sliding frame is slid to a predetermined position for each model. It has been configured.

[0006]

In the foaming device of the heat insulating cabinet of the present invention having the above structure, the distance between the side plates provided on the sliding frame can be adjusted to the width of the cabinet by rotating the left and right screws.

Further, after the inner jig is positioned by the positioning pin, when the sliding frame is slid to match the side plate spacing with the cabinet width dimension, the interlocking rail is sandwiched by the sandwiching member to form the inner jig. Can be fixed.
