Description

Off-line cold and hot water circulation connecting device of annular door body foaming line

Technical Field

The utility model relates to a foaming technology of a refrigerator, in particular to a cold and hot water connection structure on a door body annular line.

Background

The insulation layer of the refrigerator body is usually formed by foaming polyurethane. The foaming of polyurethane is carried out by maintaining the foam at a relatively high temperature. In a refrigerator door foaming production line having an annular rail, the annular rail includes two straight rails parallel to each other and an arc rail connected between ends of the two straight rails. The annular track is provided with a plurality of foaming die frames which are arranged at equal intervals. During foaming operation, each foaming die carrier moves circularly along the annular track. When the foaming mould frame circulates on the annular track for one circle, the foaming procedure of one door body is completed: namely, feeding the door liner, injecting foaming material, closing the mold, maintaining the foaming at high temperature, cooling after solidification, and opening the mold for blanking. And each foaming procedure corresponds to the corresponding position of the foaming mould frame on the annular track. With this structure, if the foaming heating rate is low and the cooling rate is low, the required endless track is long. While reducing the speed of movement of the foaming mold frame may reduce the length requirement of the endless track, this necessarily also reduces production efficiency. In this case, the conventional heating and cooling methods are not applicable. The most suitable way is to heat with circulating hot water and cool with circulating cold water. Hot water supply and cold water supply outside the line are needed for the foaming mold frame to inject the circulating hot water and the circulating cold water. And the foaming mould frame continuously moves on the annular track. Thus, the problem of how to connect the hot water supply source and the cold water supply source which are out of line to the foaming mould frame which moves continuously and circularly is solved.
