Embodiment Construction
[0023] Such as Figure 1-Figure 4 As shown, the refrigerator door shell fillet bending forming mold includes an upper mold and a lower mold. The upper mold is provided with an upper mold pressing plate 22, the lower mold is provided with a forming punch 6, and the upper mold is provided with a tool for bending rounded corners. Turning plate 17 and turning plate fixing block 16, turning plate 17 and turning plate fixing block 16 are connected by rotating shaft 15, and turning plate fixing block 16 is provided with arc-shaped chute, when turning plate 17 rotates, rotating shaft 15 is in the arc-shaped chute Sliding inside, the upper die is provided with a turning plate driving block 20 and a device for turning back. The rotating shaft slides in the arc-shaped chute, which can ensure that during the bending and forming process, the turnover plate 17 can be turned over under the action of the turnover plate driving block 20, and the turnover plate 17 itself can have a rotation alo...

The invention relates to the technical field of bending molds, in particular to a refrigerator door shell circular bead bending mold. The mold comprises an upper mold body and a lower mold body, an upper mold material pressing plate is arranged on the upper mold body, a molding male mold is arranged on the lower mold body, a turning plate used for bending a circular bead and a turning plate fixing block are arranged on the upper mold body and are connected through a rotating shaft, and an arc-shaped sliding groove is formed in the turning plate fixing block; when the turning plate rotates, the rotating shaft slides in the arc-shaped sliding groove, and a turning plate driving block and a device for enabling the turning plate to return are arranged on the upper mold body; the manner that the turning plate rotating shaft runs along the sliding groove when the turning plate is turned over is adopted, the rotation center of the turning plate is not fixed, and therefore when the circular bead is bent, the turning plate can rotate in a manner of adapting to the circular bead to be molded, materials of the outer edge can be evenly shrunk, and the wrinkling phenomenon caused by stacking of the materials on the edge is avoided; and surface quality of a refrigerator door shell is ensured, and the requirement that the molded refrigerator door shell circular bead can reach the standard of drawing paper is met.
Description
technical field [0001] The invention relates to the technical field of bending molds, in particular to a round corner bending forming mold for refrigerator door shells. Background technique [0002] At present, the materials used for the refrigerator door shell are VCM board, stainless steel and PCM board. The surface quality of the refrigerator door shell requires high precision in all dimensions, and the surface must not have bumps or scratches visible to the naked eye. [0003] There are two conventional procedures for bending the rounded corners of the refrigerator door shell. One is to use stamping to bend the refrigerator door shell directly and form rounded corners at the bend. But in fact, the bend is formed at a right angle. Wrinkles appear at the bends, and the smaller the rounded corners are, the more obvious the wrinkles are, which affects the surface quality of the refrigerator door shell. The other is to use the method of folding the rounded corners first and...
