Description

Door stopper corner back-off movable turning plate structure Technical Field The invention relates to the technical field of refrigerator manufacturing, in particular to a door stopper corner back-off movable turning plate structure. Background In the use process of the refrigerator, the sealing performance between the door body and the refrigerator body directly determines the heat preservation effect and the energy efficiency level of the refrigerator, and the sealing rubber strip is used as a core sealing component, so that the stability of installation and fixation of the sealing rubber strip is the key for guaranteeing the sealing performance. In the prior art, an inner container of a refrigerator door is generally provided with an omega groove to realize embedding fixation of a sealing rubber strip, a back-off structure is generally designed in four vertical edge areas of the omega groove to prevent the sealing rubber strip from shifting, the sealing rubber strip is stably limited through a mechanical clamping effect, and the problems that the sealing rubber strip moves and falls off in the vertical edge areas can be effectively avoided. However, the corresponding back-off structure cannot be arranged in the omega groove of the four corner areas of the refrigerator door liner, and the sealing rubber strip is not effectively limited in the corner areas due to the fact that the back-off is lack of fixing at the corners of the door liner, and after a period of use, the sealing rubber strip is affected by factors such as door body switch vibration, ageing shrinkage of the sealing rubber strip, temperature change and the like, and edge warping phenomenon of the sealing rubber strip at the corners is very easy to occur. Disclosure of Invention Aiming at the defects of the prior art, the invention provides a door stopper corner back-off movable turning plate structure, which has the advantage of realizing the back-off forming of a door liner corner to firmly fix a sealing rubber strip, and solves the problem that the sealing rubber strip is easy to warp due to the fact that the back-off cannot be arranged in a corner area of the refrigerator door liner in the prior art. In order to solve the technical problems, the invention provides the following technical scheme: The door stopper corner back-off movable turning plate structure comprises a mold main body for molding and processing a door liner, wherein a copper turning strip is arranged on the outer side of the mold main body, and a movable turning plate assembly is arranged on the mold main body. The movable turning plate assembly comprises a fixed seat arranged on the inner side wall of the die body, a mounting groove is formed in the inner side of the fixed seat, a spring seat is arranged on the inner bottom wall of the mounting groove, a rotating shaft is movably arranged on the spring seat, a turning block is arranged on the rotating shaft, two ends of the turning block extend to the end face of the copper turning strip, a reset spring is arranged in the spring seat, and one end of the reset spring is in butt joint with the turning block. Preferably, the fixing seat is provided with a shaft hole matched with the rotating shaft, and the rotating shaft is in transition fit with the shaft hole after penetrating through the middle part of the overturning block. Preferably, one end of the overturning block, which is close to the reset spring, is provided with a boss, the reset spring is sleeved outside the boss, and the length of the boss is not less than the compression stroke of the reset spring. Preferably, the spring seat is a cylindrical structure with one end open, the open end of the spring seat faces the overturning block, and the inner side wall of the spring seat is provided with a guide chute.
