Refrigerator door foaming production line

Abstract

The invention discloses a refrigerator door foaming production line. The refrigerator door foaming production line comprises a plurality of transversely-arranged foaming machines. Overturning air cylinders are arranged on the two sides of bases of the foaming machines. Upper molds are hinged to machine bodies of the foaming machines. The output ends of the overturning air cylinders are connected to the two sides of the upper molds. Locking hooks are arranged on the front sides of the machine bodies of the foaming machines and connected with locking air cylinders. The foaming machines are internally provided with installing cavities. Air bags are arranged at the bottoms of the installing cavities of the machine bodies. Lower mold plates are arranged on the upper sides of the air bags. The four corners of the bottom faces of the lower mold plates are connected with limiting columns. Charging mechanical arms are arranged on the upper sides of the foaming machines. According to the refrigerator door foaming production line, the technology is easy to operate, the two charging functions are achieved, the technical requirement of foaming of a conventional refrigerator door can be met for production, the lower mold plates are jacked through the air bags, closing is stable and free of noise, abrasion is avoided, durability is achieved, cost is saved, and losses are reduced; and meanwhile the occupied area of a plant is reduced, the requirement of mixing production is met, and the product quality is improved.

Description

technical field [0001] The invention relates to the field of refrigerator door foaming production lines, in particular to a refrigerator door foaming production line. Background technique [0002] Nowadays, in the domestic refrigerator door foaming production line, the fixtures adopt the upper mold frame that can be lifted up and down, and the closed mold foaming locking device is a push rod type. The push rod will be worn for a long time, causing the closed size to become larger, which is easy Bubble leakage occurs, which makes the product unqualified. The upper mold frame with lifting is mostly made at the hinge, and the hinge is easy to be undurable; the conventional filling method is to open the mold and fill vertically, and there are also clamps for closed mold filling. If there is no combination, two sets of production lines may be needed when the product process is different, resulting in waste of equipment. Nowadays, high-end refrigerators often need closed-mold fil...

[0002] Nowadays, in the domestic refrigerator door foaming production line, the fixtures adopt the upper mold frame that can be lifted up and down, and the closed mold foaming locking device is a push rod type. The push rod will be worn for a long time, causing the closed size to become larger, which is easy Bubble leakage occurs, which makes the product unqualified. The upper mold frame with lifting is mostly made at the hinge, and the hinge is easy to be undurable; the conventional filling method is to open the mold and fill vertically, and there are also clamps for closed mold filling. If there is no combination, two sets of production lines may be needed when the product process is different, resulting in waste of equipment

Nowadays, high-end refrigerators often need closed-mold filling to meet the requirements of door body foaming, and the closed-mold filling equipment alone cannot meet the production of conventional refrigerators.
