Problems solved by technology
[0005] When using the glaze joint method to make porcelain pieces, since each component has been formed, there are gaps in the joint part during splicing, and the strength of the joint part is insufficient and easy to break with only glaze or glue;
[0006] When using the core-embedded method to make ceramic parts, since the position of the core itself in the mold is difficult to fix, the core will inevitably shift when the material is added to form an embryo, which will affect the quality of the finished product. If the internal dimensional accuracy is high, this method not suitable

Embodiment Construction
[0041] In order to describe in detail the technical content, structural features, achieved objectives and effects of the present invention, the following is a detailed description in conjunction with the embodiments and accompanying drawings.
[0042] For example, in an embodiment, a ceramic piece with a "h"-shaped ceramic three-way tubular structure is to be made, and the shape is the same as Figure 4 The whole body 1 before sintering shown includes a straight main pipe channel 10, an L-shaped branch pipe channel 20, a main pipe channel inlet 101, a main pipe outlet 102, a threaded branch pipe inlet 201, and a branch pipe and main pipe channel connection port 202.
[0043] The "h"-shaped ceramic three-way structure in the embodiment requires an error of dimensional accuracy of <0.1mm. If the usual one-time molding is used, the structure of the L-shaped branch pipe channel will have difficulty in demolding and cause molding failure; if the prefabricated "h" is used Forming in the...

The invention aims to provide a method and a mould external member for manufacturing a ceramic element blank, and the method comprises the following steps: arranging one or a plurality of construction member blanks in a mould cavity to obtain an assembly blank; and sintering the assembly blank into the ceramic element. Because the construction member blanks which serve as parts of the assembly blank are manufactured firstly so as to further manufacture the assembly blank, the assembly blank with a complex internal or external shape can be manufactured, the sintered product has the advantages of high precision and high junction strength.
Description
Technical field [0001] The invention relates to a method for manufacturing a ceramic embryo body and a mold kit used for manufacturing the ceramic embryo body. Background technique [0002] Compared with ordinary ceramics, high-frequency porcelain has the advantage of high dimensional accuracy. Its molding mainly adopts injection (die-casting) molding method. For some ceramic products with higher precision requirements, high-frequency porcelain is generally used. Due to the inherently poor fluidity of ceramic raw materials, the main difficulty lies in demoulding when producing some ceramic parts with relatively complex structures. There is no better solution before the present invention. [0003] For the molding of ceramic parts with more complex structures, currently there are mainly methods such as glaze joining and core inserting. [0004] The glaze joining method is to decompose the porcelain piece into multiple components to form separately, and then use the glaze water to spli...
