Description

Technical Field

[0001] The utility model relates to the technical field of die-cast aluminum parts, in particular to a novel hanger for auxiliary anodizing of die-cast aluminum parts. Background Art

[0002] Hangers are used to hang workpieces and direct current to the workpieces during electroplating and related operations. For plated parts with complex geometric shapes, some must be equipped with auxiliary anodes, auxiliary cathodes or shielding plates. The non-contact parts on the surface of the hangers used for aluminum anodizing and plastic electroplating must have a good insulating layer. Most of the uses are to directly hang die-cast aluminum parts on the surface of the hangers, which results in the die-cast aluminum parts not being firmly fixed on the hanger surface.

[0003] After consulting the literature, it is learned that the existing patent (publication number: CN220724371U) discloses a new type of hanger for auxiliary anodizing of die-cast aluminum parts, including a hanger, the top of the hanger is connected to a support frame, the top of the support frame is fixedly connected to a hook; a movable plate, two groups of movable plates are arranged inside the hanger, and the two sides of the movable plate are respectively connected to limiting blocks; a fixed cavity, the fixed cavity is opened on the inner side wall of the hanger, and the interior of the fixed cavity is connected to a limiting rod.

[0004] Although the above-mentioned prior art utilizes the elastic force of the second spring itself to move the two sets of movable plates to the initial position and away from each other, and allows the two sets of elastic fixing plates to fix the die-cast aluminum part, thereby clamping and fixing the die-cast aluminum part, in actual use, if the elastic fixing plate is expected to fix the die-cast aluminum part with high stability, the second spring itself needs to have large elasticity, but this will cause the staff's hands to apply a large force to press the two sets of movable plates, which can easily cause fatigue in the staff's hands. If the second spring has low elasticity, it will lead to insufficient stability in fixing the die-cast part, which has low practicality and is inconvenient to operate. In view of this, we propose a new hanger for auxiliary anodizing of die-cast aluminum parts to solve the above problems. Utility Model Content
