Technical Field

[0001] The present invention belongs to the technical field of vehicle refrigeration systems, and particularly relates to a foaming device and a foaming method for a core of a vehicle refrigerator refrigeration system. Background Art

[0002] Refrigerators can be classified into absorption refrigerators, compression refrigerators, and semiconductor refrigerators according to the refrigeration principle. Various refrigerators provide material guarantees for the improvement of human living quality. Since absorption refrigerators do not use Freon, they protect the atmospheric ozone layer, and there are no compressors and mechanical transmission parts, and they do not generate noise during operation. Therefore, they are praised as "double green environmental protection products" by international environmental protection organizations. For example, a core structure for a new refrigerating machine disclosed in the existing patent CN202023342338.5, and a diffusion absorption refrigeration core disclosed in the existing patent CN200820127416.X. Therefore, absorption refrigerators are also widely used in vehicles.

[0003] The core of the absorption refrigerator needs to go through a foaming process to form foamed cotton in the evaporation section of the core to achieve the effect of heat preservation and insulation. The existing core foaming molds need to clamp the core on the foaming mold and then place the foaming mold on the foaming machine for foaming, which has the following defects: the operation of clamping the core onto the foaming mold is cumbersome, time-consuming, and the production efficiency is low, and multiple sets of foaming molds need to be matched with the foaming machine to achieve non-stop operation, resulting in a high cost.

If the second aluminum foil (33) is not placed in step S1, then the second aluminum foil (33) is placed on the movement mechanism (3) at this place, then the foaming material (34) is injected from the material injection port of the second aluminum foil (33), and then the pressing plate (23) is pressed on the second aluminum foil (33). At this time, the pre-installation plate (13), the first aluminum foil (32), the evaporation pipe (31) of the movement mechanism (3), the second aluminum foil (33) and the pressing plate (23) are arranged in sequence from bottom to top, and then use the second pressing mechanism (22) to fix the pressing plate (23). S3, foaming: Move the foaming device (2) to the foaming machine for foaming.

10. The foaming method of the core of the vehicle-mounted refrigerator refrigeration system according to claim 9, characterized in that: A hook (131) is provided at the bottom of the pre-mounted plate (13). An avoidance opening is formed in the foaming cavity (211), and the hook (131) is exposed through the avoidance opening. A rotary pressing cylinder (24) is provided on the second support mechanism (21), and the rotary pressing cylinder (24) is used to tighten the hook (131); in step S2, the movement core (3) is placed on the second support mechanism (21), and the evaporation pipe (31) of the movement core (3) is located in the foaming cavity (211). Then, the rotary pressing cylinder (24) is started, and the output end of the rotary pressing cylinder (24) rotates and tightens the hook (131) until the pre-mounted plate (13) is closely attached to the foaming cavity (211).

11. The foaming method of the core of the vehicle-mounted refrigerator refrigeration system according to claim 9 or 10, characterized in that: In step S1, a heat-conducting paste is provided between the first aluminum foil paper (32) and the evaporation pipe (31) of the movement core (3).
