[0005] 2. Most of the current forming molds do not have the functions of quantitative feeding and uniform flow guiding, and thus cannot guarantee the feeding quantity and speed of the powder material. Therefore, to a certain extent, it reduces the precision and effect of mold production;

[0006] 3. The material barrels used in most of the current forming molds do not have the functions of vibrating and stirring the material and conveying it, and it is very easy to have the problem of powder caking causing unsmooth transmission.
