The powder slurry consists of metal powder or fiber and mother solution, and has certain concentration; the powder and the mother solution are well wetted, and the surface of the particles is not adhered with gas; the powder slurry is uniformly suspended and does not settle, etc. The raw material powder for slip casting is preferably fine powder, and the particle size is usually 5-10 μm. The mother solution is a mixed solution of various additives and water. Additives are of various compositions, including binders, dispersants, suspending agents (stabilizers), foam removers, titrants, and the like. In addition, in order to prevent sticking, a mold release agent such as silicone oil, soapy water, etc. should be sprayed on the gypsum mold wall before casting. The powder and mother liquor are continuously stirred until uniform suspension slurry is obtained, and the gas adsorbed on the surface of the powder is removed, and then the powder and the mother liquor are poured into a mold. Standing for a period of time, and obtaining the required injection piece after the porous gypsum mold absorbs the liquid in the slurry. The injection molded blank should be properly dried so that the blank is properly shrunk and can be ejected from the mold. And (5) completely drying and baking the injection molding after the mold stripping. This technique has the following disadvantages: 1. the method needs to remove bubbles manually, so that the compactness of the obtained die cannot be ensured; 2. according to the method, the thickness of the solidified die is estimated by a visual observation method, and the die with accurate thickness cannot be obtained; 3. the gypsum mold used by the method has uniform porosity, so that the slurry with different contact surfaces has inconsistent permeation and solidification rates, and finally the wall thickness of the obtained mold is uneven in the same time period, the processing difficulty is additionally increased, and the subsequent use of the mold is influenced; 4. according to the method, redundant slurry is required to be poured manually and cannot be discharged uniformly, so that the thickness of the inner wall is different.
