[0008] The side plates are arranged at the openings at both ends of the frame, so that a molding cavity is formed inside the frame; and

[0009] The side plate is suitable for being movably connected with the frame.

[0010] Furthermore, the frame includes: four frame plates hinged in sequence;

[0011] The four frame plates form a square frame.

[0012] Furthermore, the frame includes: four frame plates hinged in sequence;

[0013] The frame plate at the first end is hinged to the frame plate at the last end; and

[0017] The beneficial effects of the utility model are:

[0018] (I) The utility model surrounds the frame plate on the outside of the battery module, presses one side plate on one end of the battery module through the battery cell installation position, and limits the side plate and the frame plate by bolts, so that one side plate is downward, and after the foam liquid is injected inward, the other side plate is pressed on the other end of the battery module and fixed by the engagement of nuts and bolts, so that the foam liquid foams in the molding cavity. When the foam and the battery module are integrated, the nut is removed and the side plate is taken out, so as to achieve the effect of facilitating demoulding and saving time.

[0019] (ii) The utility model surrounds the outer side of the battery module with a frame plate. When any frame plate is opened, the two side plates are buckled on the two ends of the battery module through the battery cell mounting position. After being placed in the frame, the foam liquid is injected into the frame plate, and the frame plate is contacted with the other side frame plate, and fixed by bolts and nuts, so that the foam liquid foams in the molding cavity. When the foam and the battery module are integrated, the nuts are removed and the side plates are taken off, and the frame plate is unfolded to take out the battery module, thereby achieving the effect of facilitating demoulding and saving time.
