[0002] Powder metallurgy is a process technology that produces metal powder or uses metal powder (or a mixture of metal powder and non-metallic powder) as raw material, and manufactures metal materials, composite materials and various types of products through forming and sintering.

[0003] Referring to the patented powder metallurgy forming machine and its powder feeder (Announcement No.: CN209303709U), the metal powder in the powder storage space falls into the quantitative hole on the powder feeding slider. Under the action of the block, the quantitative hole is aligned with the leakage hole, and then the metal powder in the quantitative hole and the leakage hole enters the mold cavity through the feed hole to complete the quantitative feeding.

[0004] However, it can only quantify a fixed amount of powder. When the required amount of powder changes, it can only replace the powder feeding slider with quantitative holes of different sizes, but cannot quickly adjust the powder quantitative. Not only is the disassembly and assembly of the powder feeding slider time-consuming and laborious, but also a large number of powder feeding sliders need to be prepared to meet different quantitative requirements, wasting financial and material resources.

[0005] Therefore, a powder metallurgy quantitative infusion structure is proposed to solve the above-mentioned problems. Utility Model Content
