The mould assembly includes a die holder and a female die arranged along the first axis. The female die and the die holder define a model cavity for filling metallurgical powder. The punch assembly includes a punch sleeve, which is pressed into the model cavity along the first axis to press and form the metallurgical powder. The vibration assembly includes a knocking structure and a toothed disc. The toothed disc is installed on the female die and can rotate around the first axis and slide synchronously with the female die along the first axis. The driving assembly drives the toothed disc to rotate around the first axis. The knocking structure knocks the toothed disc when it rotates, thereby causing the female die to vibrate. The female die side wall applies a vibration effect to the powder in the model cavity, making the metallurgical powder as evenly distributed as possible in the model cavity. The metallurgical powder in the model cavity is uniformly compacted by the punch sleeve, improving the performance of the compacted body.
