The cooperation between the feeding mechanism and the forming mechanism can make the metal powder more uniformly laid in the die, thereby eliminating the level difference after product forming and improving the overall quality of the product. The feeding mechanism realizes the feeding and discharging operations of the product, and the metal powder is filtered through a filter plate, thereby balancing the overall quality of the product.

[0004] When the device in the above-mentioned patent is used to form metal powder, the baffle is used to push the metal, but the width of the baffle is greater than the diameter of the extrusion cavity. When the baffle pushes the metal powder into the extrusion cavity, a large amount of residual powder will be generated on both sides of the baffle. After the baffle is reset, the residual metal powder on both sides may not be pushed into the extrusion cavity again, causing waste of metal powder and reducing the practicability of the device. Moreover, the metal powder is not sieved, which may cause defective products. UTILITY MODEL CONTENT
