[0002] The existing refrigerator box body is insulated by foaming the foaming resin in the box wall cavity. The foaming resin is directly filled into the mold, melted by heat, and forms a gas-liquid saturated solution. Through nucleation, a large number of tiny bubble nuclei are formed, and the bubble nuclei grow to form a foam plastic part.

[0003] At present, after the foaming mold is prepared for the refrigerator body, the operator needs to perform demoulding, which not only increases the labor intensity of the operator, but also greatly reduces the processing efficiency. In this regard, the Chinese patent with announcement number CN220741904U discloses a rapid demoulding device for refrigerator foaming molds, which can quickly demould the mold, solves the problem that after the foaming mold is prepared for the refrigerator body, the operator needs to perform demoulding, reduces the labor intensity of the operator, and improves the processing efficiency.

[0004] However, in the prior art, when the mold with such a demoulding mechanism is actually used, each time the foaming operation is performed, only one side panel of the refrigerator can be foamed separately, and the working efficiency is low, and it is difficult to meet the existing foaming production needs.

[0005] Therefore, the present application provides a box foaming mold to solve the above technical problems. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a box foaming mold to solve the problem in the prior art that, when the mold with such a demoulding mechanism is actually used, each time the foaming work is carried out, only one side panel of the refrigerator can be foamed separately, the working efficiency is low, and it is difficult to meet the existing foaming production needs.

[0011] Optionally, handles are symmetrically fixed on both sides of the top of the lower mold base and the upper mold base.

[0012] Optionally, a plurality of water cooling pipes are arranged in the lower mold base, and the water cooling pipes are distributed in the inner wall between two adjacent foaming cavities, and both ends of the water cooling pipes are provided with openings, which are located on the upper end surface of the lower mold base.

[0013] Optionally, two butt joints are installed on the upper end surface of the upper mold base, and the lower end of each butt joint is connected to a plurality of cooling inserts corresponding to the number of the foaming cavities, and the cooling inserts are plugged into and matched with the end openings of the water cooling pipes.

[0035] Cooperate Figure 3 As shown, a plurality of parallel foaming cavities 301 are arranged in the lower mold base 3, the top of the foaming cavity 301 is open and located on the upper end surface of the lower mold base 3, and a plurality of upper modules 401 are fixed to the lower end surface of the upper mold base 4, and the plurality of upper modules 401 are docked and matched with the upper ports of the plurality of foaming cavities 301 one by one to form a closed foaming chamber.
