Description

Technical Field

[0001] The utility model relates to the field of ceramic moulds, in particular to a ceramic mould with ears. Background Art

[0002] Ceramics is a widely used material with the advantages of high strength, high hardness, wear resistance, corrosion resistance, and high temperature resistance. The main molding processes of ceramics include powder molding, slip injection molding, extrusion molding, dry pressing molding, etc. Among them, extrusion molding is a commonly used method, which is to mix ceramic powder with a certain proportion of organic or inorganic additives, and then put it into an extruder for extrusion, so that it is formed through a mold, and then subjected to subsequent treatments such as drying and sintering to finally form the desired ceramic products. Ceramic products have different shapes and functions. Some ceramic products need to have ears, such as ceramic cups, ceramic pots, ceramic jars, etc. These ceramic products with ears are generally formed by sticking porcelain ears on both sides of the porcelain body after the porcelain body is formed, and then undergoing subsequent treatments such as drying and sintering to form the desired ceramic products. However, the ceramic products made in this way have low strength at the connection between the porcelain body and the porcelain ears. During use, the porcelain ears are easily separated from the porcelain body, which causes damage to the porcelain body and affects the use of porcelain utensils. Utility Model Content

The ear groove 22 can be fan-shaped, which can facilitate the separation of the ceramic ear from the mold after the ceramic is formed, and avoid damage to the ceramic ear during the separation process of the ceramic ear from the mold.

[0026] In some embodiments, a limiting ring groove 13 is coaxially provided on the outside of the limiting boss 12, and the limiting ring groove 13 is plugged into and matched with the inner mold 2, so that the relative position between the inner mold 2 and the outer mold 1 can be more stable and accurate, preventing the movement and deflection of the inner mold 2 during the molding process, ensuring the shape and size of the molding cavity 21, and thus ensuring the molding quality of the product.
