Description

Technical Field

[0001] The utility model relates to the field of powder metallurgy, in particular to a powder metallurgy mold. Background Art

[0002] Powder metallurgy is a process technology that produces metal powder or uses metal powder (or a mixture of metal powder and non-metal powder) as raw material, and then forms and sinters it to produce metal materials, composite materials and various types of products. Powder metallurgy is similar to the production of ceramics, both of which belong to powder sintering technology. Therefore, a series of new powder metallurgy technologies can also be used to prepare ceramic materials. Due to the advantages of powder metallurgy technology, it has become the key to solving new material problems and plays a vital role in the development of new materials.

[0003] Powder metallurgy includes powder making and products. Powder making is mainly a metallurgical process, which is consistent with the literal meaning. Powder metallurgy products often go far beyond the scope of materials and metallurgy, and are often cross-disciplinary (materials and metallurgy, machinery and mechanics, etc.) technology. In particular, modern metal powder 3D printing integrates mechanical engineering, CAD, reverse engineering technology, layered manufacturing technology, CNC technology, material science, and laser technology, making powder metallurgy product technology a modern comprehensive technology across more disciplines.

[0004] However, when adding powder, most pressing molds cannot replace the pressing head, resulting in a single mold that can only press and form workpieces of a single thickness. It is not convenient to quickly remove parts, and there is no dust prevention, which causes material scattering and waste, thereby affecting the stability of subsequent continuous pressing and forming, and causing unnecessary waste of raw materials.
