Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of molds, in particular to a dust cover flanging mold. Background Art
[0002] Molds are divided into injection molds, die-casting molds and stamping molds. In order to reduce resistance, increase structural strength and facilitate installation, the automobile brake dust cover will have an arc-shaped structure and a large number of convex ribs. However, this also causes the dust cover to be subjected to not only vertical forces but also lateral forces during stamping. Existing dust cover molds all adopt a split structure for easy maintenance. Traditional molds are fixed and fixed by bolts. During stamping, the bolts are subjected to lateral forces, which will cause the bolts to twist and deform, resulting in misalignment between the molds, affecting the accuracy of the processing. When the bolts are twisted, it is also difficult to disassemble them later. Utility Model Content
