Embodiment Construction

[0037] figure 1 It is a schematic diagram of the device when performing the foaming process of the refrigerator 100 according to an embodiment of the present invention. figure 2 is a schematic flowchart of the foaming process of the refrigerator 100 according to an embodiment of the present invention. The refrigerator 100 in the embodiment of the present invention includes a box body 110 and a door body (not shown in the figure). The box body 110 includes an outer shell 120 and an inner tank 130 . The interior of the liner 130 defines a storage space 140 . A foaming space 150 is defined between the inner tank 130 and the outer shell 120 . The storage space 140 constitutes one or more storage compartments. The door body is arranged on the front side of the storage compartment for opening and closing the storage compartment. The number and structure of storage compartments can be configured according to requirements. For example, the storage compartment includes a refrige...

Abstract

The invention provides a foaming process of a refrigerator. The foaming process comprises the steps that a refrigerator body of the refrigerator is placed in a mold cavity; foaming filling of the refrigerator is realized by adopting a polyurethane foaming reaction; and when the polyurethane foaming reaction is carried out, the pressure in the mold cavity is dynamically adjusted. According to the foaming process of the refrigerator, when the refrigerator is subjected to the polyurethane foaming reaction, the pressure in the mold cavity is dynamically adjusted, the thermal insulation performanceis improved, the cost of foaming materials can be reduced, the curing time is shortened, the number of surface bubbles is reduced, and surface skinning is reduced.

Description

technical field [0001] The invention relates to the technical field of refrigeration and freezing, in particular to a foaming process for a refrigerator. Background technique [0002] Refrigerator foaming generally refers to rigid polyurethane foaming, and the foam is between the outer shell and the inner tank of the refrigerator. The performance of the foam and the production process determine the performance of the refrigerator. Existing refrigerators use constant pressure for foaming, which has the problems of poor thermal conductivity of the product, high cost of foaming materials, and long time. Contents of the invention [0003] One object of the present invention is to provide a foaming process for a refrigerator that can improve thermal insulation performance and reduce the cost of foaming materials. [0004] A further object of the present invention is to make it easier to regulate the pressure of the foaming process of the refrigerator. [0005] In particular,...
