Furthermore, the connection of the electric supply cord to the inner jig (d) and the connection of the air supply hose were manually performed every time the inner jig (d) was switched, which was troublesome. It is an object of the present invention to provide a foaming device for a heat insulation cabinet which is safe and has high production efficiency.

[0004]

In order to achieve the above object, a foaming apparatus for a heat insulating cabinet according to the present invention has a main body constituted by 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 laterally slidable sliding frames on the left and right of the inner jig, and both outsides of the cabinet A pair of side plates that are in contact with the wall surface 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. And a plurality of left and right screws in the near and far directions that make the two closer to each other, a positioning pin provided on the upper portion of the inner jig, and both or one of an electric supply port and an air supply port. And a base for holding the inner jig, which is provided so as to face the upper surface of the sliding frame and the upper facing surface of the sliding frame, and a plurality of fitting holes for fitting the positioning pins to the base and a plurality of fittings for the electric supply port. Both the power supply plug and the air inlet that fits into the air supply port, or one of them, are provided on the upper surface of the base, and the sliding frame is slid to a predetermined position for each model, and the scissors are inserted. It is configured to include a pair of fitting rails that fit with the members.

[0005]

With the above structure, the foaming device of the heat insulating cabinet of the present invention can adjust the distance between the side plates provided on the sliding frame to the cabinet width dimension by rotating the left and right screws. In addition, after positioning the inner jig with the positioning pins, slide the sliding frame to match the side plate spacing to the cabinet width dimension, and insert the fitting rail with the sandwiching member to fix the inner jig. be able to. At the same time, the electricity supply port and power supply plug, and the air supply port and air intake can be connected.
