Among them, forming equipment is often used, such as a powder metallurgy forming equipment disclosed in the patent with publication number CN212598863U. In this powder metallurgy forming equipment, when the first telescopic cylinder extends downward, it drives the slide plate to slide downward, the slide plate squeezes the air bag, and the air bag sprays air through the air nozzle to clean the powder scattered on the second support plate, so as to avoid the accumulation of powder on the second support plate, which affects the subsequent feeding and pressing plate from smoothly entering the extrusion die cavity, and no manual cleaning is required;

[0003] However, in the actual production process, due to the different extrusion molds and different degrees of extrusion, the slide plate is used to extrude and deflate the air bag to blow the powder at the same time, resulting in excessive extrusion or insufficient extrusion and exhaust gas. After the powder is blown, it is not collected, and the production site still needs to be cleaned again. Therefore, the workload of cleaning is not actually reduced.

[0004] Based on the above description, there is an urgent need for a powder metallurgy molding equipment that can simultaneously mold and collect waste. Utility Model Content
