[0002] Mobile phone vibrators are widely used in motor accessories and mobile phones, and are used in huge quantities. The process generally involves stamping powder alloys and then sintering them in a sintering furnace. The general method of pressing powder alloys is to manually hold a feed shoe filled with materials, and move the feed shoe between each stamping to add the materials to the pressing mold. This method has several problems: 1. The material in the feed shoe is unevenly distributed when it is sent down, which can easily cause product stamping defects and prolong the pressing time; 2. The bottom of the feed shoe is easily damaged after frequent wear, resulting in the scrapping of the entire feed shoe, which is costly. In response to the above two problems, the existing powder alloy pressing device is improved and optimized. Utility Model Content
