TECHNICAL FIELD
[0001] The present application relates to the technical field of refrigerator foaming mold, in particular to a refrigerator door foaming mold. BACKGROUND
[0002] With the rapid development of economy, people's living standards are improving. Refrigerator becomes a necessary household appliance for every family. Refrigerator, freezer is a kind of refrigeration equipment that keeps constant low temperature, and is also a kind of civil product that keeps food or other objects in constant low temperature cold state. The cabinet has a compressor, ice maker for ice making, or a cabinet or box with a refrigeration device. The refrigerator, freezer foaming process refers to the production process of the foaming material used in the filling between the inner and outer layers of the refrigerator, freezer. The refrigerator, freezer foaming process is different from general plastic foaming, and has more strict requirements and more specific purposes.
[0003] The refrigerator, freezer has foaming layer in the cabinet and door body. For the door body foaming production process, the highest process standard is adopted. The door body is a sealing part of the cabinet cold (frozen) room. When the door body is matched with the cabinet, the sealing is ensured by the adsorption of the door seal and the cabinet frame, and the irregular protruding structure of the door body. The existing refrigerator door production adopts rotating hub type, ground rail type and single mold opening and closing type.
[0004] For the rotating hub type production foaming mold door body opening and closing, due to the high step of the door body hanging bottle frame, the step root is cracked under the influence of the door body's own gravity when the mold is opened, which is called "cracking" in the industry. In addition, the plastic suction door body used for the door body needs to be manually attached to the upper mold of the foaming mold during production. Due to the large area of the door body, it is easy to form an "air chamber" between the door body and the upper mold during attachment, which causes the door body to not better adhere to the mold, and the door body will fall off during mold closing, that is, "choking". In addition, when the refrigerator is foamed, the mold is opened, and the upper mold is too tight, which causes the "hanging door" phenomenon. SUMMARY
[0005] In order to overcome the prior art production of the door body of the foaming mold opening and closing, due to the bottle frame step of the door tank is too high, the step root is cracked under the influence of the door body gravity when the mold is opened, which is called "tank crack" in the industry.

[0037] The working principle of the application:
[0038] A refrigerator door body foaming mold, because the mold groove opened in the middle of the upper die plate bottom matches the door tank step, when manually attaching the door tank to the upper die, the airflow generated by the middle of the upper die core and the door tank is discharged to the outside of the mold through the air vents opened on the left and right sides of the mold groove, so that the door tank and the mold are better attached. In this way, it can better prevent the door tank from not being attached well and falling off due to poor clamping. In addition, it prevents the door tank from sagging after the door body foams. The air vents opened facilitate the cleaning of the free foam liquid generated inside later.
[0039] Further, when the refrigerator foams, the upper die is too tight when the mold is opened, which is easy to cause the "hanging door" phenomenon. The hanging block is used to lock the upper and lower end covers of the door body to take them out of the upper die, preventing the door body in the lower die from falling during the opening process. The locking block can prolong the opening time, so that the door body is slowly opened only under the influence of gravity to prevent "tank cracking". Reduce unnecessary production losses.
