Foaming molding part and refrigerator with same

Abstract

The invention discloses a foaming molding part and a refrigerator with the foaming molding part, the foaming molding part comprises a shell, a foaming cavity for foaming of a foaming material is formed in the shell, an exhaust hole for communicating the foaming cavity with the outer space of the shell to exhaust air during foaming of the foaming material is formed in the shell, and the foaming cavity is communicated with the outer space of the shell through the exhaust hole. The foaming molding piece is further provided with an anti-overflow mechanism matched with the exhaust hole, and the anti-overflow mechanism is provided with a movable baffle which is driven by the foaming material to rotate or translate so as to close the exhaust hole when the foaming material is foamed. Based on the design structure of the foaming molding part provided by the invention, the movable baffle of the anti-overflow mechanism is driven by the foaming material to rotate or translate, and in the foaming process of the foaming material, the movable baffle can move smoothly to close the exhaust hole, so that the overflow condition can be effectively avoided.

Description

technical field [0001] The invention relates to the field of refrigerator design, in particular to a foam molding and a refrigerator with the same. Background technique [0002] Refrigerators are used more and more in various occasions such as home and work. For now, various key technologies for refrigerator manufacturing are relatively mature. How to further optimize the refrigerator manufacturing process on the basis of existing technologies is also an important issue. research direction. [0003] During the production process of the specific refrigerator, the box body and the door body with heat preservation function are all obtained by foaming the foam cavity of the corresponding foam molded parts. The foam material involved is polyurethane. It is divided into 3 stages: milky white process, gelation process and curing process. During the specific foaming process, the air in the foaming cavity needs to be exhausted, so the corresponding foaming molded parts need to be f...

However, the analysis shows that the shrapnel involved in this patent application is based on its own characteristics. It also produces an increasing elastic force when it approaches the vent hole, and it is prone to the situation that the shrapnel cannot completely cover the closed vent hole, resulting in There is still a risk of foam overflowing from the vent
