The invention provides a rapid foaming device and a rapid foaming method. The rapid foaming device comprises a pressure keeping device and a pressure keeping mold, wherein a cavity of the pressure keeping mold has a closed structure; air holes which are selectively opened or closed are formed in the pressure keeping mold; material injection holes which are selectively opened or closed are formed in the pressure keeping mold; and air ports of the pressure keeping device are connected with the air holes in a sealing mode. Due to the arrangement of the pressure keeping device and the pressure keeping mold, after a device to be foamed is arranged in the pressure keeping device and is sealed, air pressure in the cavity of the pressure keeping mold is ensured to be in a specified range through the pressure keeping device; and therefore, after foaming materials are injected into the device to be foamed through the material injection holes, the foaming materials can more rapidly and uniformly flow in a foaming interlayer of the device to be foamed because the device to be foamed is positioned in a constant pressure state. Therefore, the foaming materials are uniformly distributed in the foaming interlayer of the device to be foamed, foaming is realized through the rapid foaming device, and thermal insulation performance of a foaming layer is improved.
Description
technical field [0001] The invention relates to foaming equipment, in particular to a rapid foaming device and a rapid foaming method. Background technique [0002] At present, refrigeration devices such as refrigerators or freezers used by people are usually provided with a foam layer, which is located in the foam interlayer of the outer shell of the refrigerator or freezer, and the foam layer can effectively keep the refrigerator or freezer warm. role. In the prior art, the refrigerator waiting for the foaming device is usually placed in the foaming jig, and the foaming jig plays a role in supporting and fixing the outer shell of the refrigerator, so that after the foaming material is injected into the foaming interlayer in the outer shell, preventing The expansion of the foam damages the shell. [0003] It can be seen from the above that the foaming fixture in the prior art only plays the role of fixing and supporting the shell, and the foaming interlayer of the shell o...
