Refrigerator door body shaping mold

Abstract

The invention provides a refrigerator door body shaping mold. A first folded edge part which is connected with a door shell and is parallel to a door shell main body is formed on the inner surface of the door shell of the refrigerator door body along the peripheral edge of the inner surface; the shaping mold comprises a lower mold adaptive to the door shell; the lower mold is provided with a movable turnover plate which is arranged along the peripheral edge of the side wall of a lower mold main body and is matched with the peripheral edge so as to form a first folded edge part. When a refrigerator door body is formed by adopting a spraying technology, firstly, the movable turnover plate is flatly placed, and is in the closed state relative to the lower mold main body at the time; then polyurethane is sprayed to inside of a cavity body formed by the lower mold main body and the movable turnover plate, and the door shell is formed after polyurethane is solidified; in demolding, firstly, the movable turnover plate is erected up, and is in the open state relative to the lower mold main body, then the door shell is separated away from the lower mold, and thus the demolding process can be simplified.

Description

technical field [0001] The invention relates to a mold for forming a refrigerator door body. Background technique [0002] The refrigerator door usually includes a door casing arranged on the outside to form an appearance surface, a door lining arranged inside the door casing, and a foam material filled in a cavity surrounded by the door casing and the door lining. Such as Figure 8 and Figure 9 As shown, the door shell 1 mainly includes a square thin plate-shaped part 1a, on the inner surface of the thin plate-shaped part 1a, a second flange 12 perpendicular to the thin plate-shaped part 1a and a The second hem portion 12 is vertically connected to and parallel to the first hem portion 11 of the sheet-like component 1a, so that an inverted L-shaped hem is formed on the inner surface of the door shell 1 along its peripheral edges, specifically as Figure 9 shown. [0003] At present, the above-mentioned refrigerator door body is mainly formed by PU (Polyurethane, polyure...

AI Technical Summary

Problems solved by technology

However, during the spraying process, there may be a little splash of raw materials at the edge of the mold, resulting in defects such as burrs and joint marks at the parting line after demoulding, which will affect the appearance of the refrigerator door.
