[0002] Metal fiber and metal powder composite sheet is an advanced composite material that combines the characteristics of metal fiber and metal powder. The preparation of this material usually involves mixing metal fiber and metal powder, and then forming a sheet with specific properties through a specific process. Metal fiber and metal powder composite sheet is widely used in aerospace, automobile manufacturing, electronic packaging, architectural decoration and other fields due to its unique properties.

[0003] Publication No. CN209255644U discloses a metal powder injection molding product shaping mold, including an upper mold base and a lower mold base; the upper mold base includes an upper mold base body, a stamping block and an elastic member; the upper mold base body is provided with a product pressure head and four slideways pointing to the product pressure head, the product pressure head is arranged in the middle of the bottom surface of the upper mold base body, and the slideways are evenly arranged along the circumference of the upper mold base body; a stamping block is slidably arranged in each slideway; the two ends of the elastic member act on the upper mold base body and the stamping block; the lower mold base includes a lower mold base body, a limit block and a fixed seat; the four limit blocks are provided with long strip-shaped screw holes parallel to the axis of the slideway, and the limit blocks are screwed to the lower mold base body through the screw holes; after the upper mold base is pressed down to a preset position, each stamping block is obliquely pressed against a corresponding limit block and is pushed by the limit block to extrude the elastic member to slide in the direction of the position of the product pressure head.

[0004] Although the above patents and the prior art can effectively solve the problem of the need to replace molds and reduce work efficiency due to changes in product specifications, before extrusion, metal powder will accumulate inside the lower die seat, which will cause the quality of the extruded sheet to be inconsistent during the extrusion process. In addition, during the extrusion process, the metal powder will generate a large amount of heat when it is extruded, causing the metal powder to adhere to the inner wall of the lower die seat. When adhesion occurs, the device needs to be stopped and the adhesion must be cleaned, which affects the efficiency of the device.
