Description

Technical Field

[0001] This utility model relates to the field of powder metallurgy mold technology, and in particular to a powder metallurgy mold powder recycling device. Background Technology

[0002] Powder metallurgy is an advanced technology that uses metal powder or a mixture of metal and non-metal powder as raw materials to manufacture metal materials, composite materials and precision products through forming and sintering processes. During the production of powder metallurgy pressing molds, a lot of excess powder will be scattered around the mold, which needs to be recycled using a powder recovery device.

[0003] For example, patent number CN205183779U discloses a powder recovery and protection device for powder metallurgy molds, comprising: a template having a mold at its center, and baffles around the template; the baffles having a notch; a powder leakage port communicating with the template through the notch; and a vacuum cleaner connected to its tail end.

[0004] For example, patent number CN214718612U discloses a powder cleaning and recycling structure for powder metallurgy, which is applied to the body of a powder die casting machine. It includes an electric telescopic rod set on the side of the powder die casting machine body. The sides of the first and second storage cylinders are both fixed with spiral springs, and the ends of the spiral springs are welded and fixed to the inner wall of the equipment box. The bottoms of the first and second rubber belts are both fixed to the top of the movable plate, and a cleaning brush plate is welded and fixed to the bottom of the movable plate.

[0005] However, most existing powder metallurgy mold powder recovery devices use single-sided dust collection or brush plate cleaning to collect powder. While single-sided dust collection can effectively collect loose powder in the mold's flat area, powder residue is easily generated in the mold grooves. Although brush plate cleaning can reach some recessed areas, there are blind spots in the cleaning, and dust is easily generated, resulting in poor collection effect. In addition, both methods require intervals between loading and unloading, which leads to repeated start-up and shutdown of the recovery components, making the operation complex, increasing the workload of each structure, and affecting the workpiece processing efficiency. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a powder recovery device for powder metallurgy molds, which solves the problems of poor powder collection effect, the need for intermittent loading and unloading, repeated start-stop of the recovery components, heavy workload of each structure, and impact on workpiece processing efficiency.

[0016] 2. In this powder metallurgy mold powder recycling device, during the pushing of the material by the pusher plate and the resetting of the dust collection hopper, the dust collection hopper collects the relatively loose powder on the surface of the workbench, thereby achieving thorough cleaning of the powder and avoiding the generation of dust.
