Problems solved by technology
[0003] In order to overcome the existing technology, in the production of ceramic products, it is necessary to dry the semi-finished ceramic products for a long time after the embryo making before proceeding to the next step, which makes the production cycle of ceramics longer and takes up more space. The defect of high production cost of ceramics, the problem to be solved by the present invention is to propose a kind of ceramic production equipment and embryo making method, which can make the ceramic embryo making and embryo drying process synchronously and quickly complete or can be completed after embryo making Omit the embryo drying process and can directly bake, so that the production cycle of ceramic products is greatly shortened and the space occupied in the ceramic production process is reduced, thereby reducing the production cost of a single piece of ceramics

Embodiment 1
[0040] Such as Figure 1 to Figure 4 Shown:
[0041] A compacting ceramic mold provided in this embodiment includes: an upper mold fixing plate 1, a punch 2, a lower mold fixing plate 3, a lower mold module 4, and a guide pillar structure 5. The upper mold fixing plate 1 is located on the top of the ceramic pressing mold, the punch 2 is fixed to the bottom of the upper mold fixing plate 1 through the upper connecting block 11, the punch 2 is fitted into the through hole in the center of the upper connecting block 11, and the upper connecting block 11 The surface is connected to the upper die fixing plate 1 through a connecting rod, the upper end of the punch 2 is in sliding fit with the groove on the lower surface of the upper die fixing plate 1, and the punching part of the punch 2 (the part that directly presses the ceramic material) The shape of the pressed ceramic part 9 (open vessel, such as tea cup, bowl, etc.) is consistent with the inner cavity structure. The lower mold...
Embodiment 2
[0049] According to another aspect of the present invention, a method for manufacturing a ceramic blank is disclosed, including the following steps:
[0050] S1. Preparation of ceramic raw materials with a water content of 3.5% to 5.5%;
[0051] S2. Add a certain amount of the above-mentioned ceramic raw material with a water content of 3.5% to 5.5% into the pressing groove 41 of the pressing ceramic mold;
[0052] S3. The punch 2 presses down the ceramic material to form a ceramic embryo;
[0053] S4. After the pressing is completed, the mold is opened to take out the pressed ceramic embryo;
[0054] S5. Put the pressed ceramic blanks into a calcining furnace for calcination, and cool the ceramic blanks after the calcination is completed.
[0055] Among them, the solid content of the ceramic raw materials is: clay 10%-20%, quartz 15%-23%, feldspar 5%-8%, aged clay 13%-16%, sericite 5%-6%, talc 6 %-7%, Lime 13%-15%, MgO1%-1.5%, ZnO1%-1.5%, BaO1.5%-1.2%, Cr2O31%-1.2%, SiC1%-1.2%, Si3N40....

Abstract
The invention discloses a pressing ceramic die and a ceramic blank manufacturing method, and belongs to the field of ceramic production. The pressing ceramic die comprises an upper die fixing plate, apunch, a lower die fixing plate, a lower die module and a guide column structure. The punch is fixed to the bottom of the upper die fixing plate through an upper connecting block. The appearance of apunch punching part is consistent with an inner cavity structure of a pressing ceramic piece. The lower die module is fixed to the position above the lower die fixing plate. A pressing groove is formed in the upper surface of the lower die module. The structure of the pressing groove is consistent to the outer surface structure of the pressing ceramic piece. The guide column structure is used formaking the punch do the up-down die sinking and assembly motion only along with the upper connecting block, and in the die assembly state, the structure of a cavity defined between the punching partof the punch and the pressing groove of the lower die module is the structure of the pressing ceramic piece. According to the disclosed pressing ceramic die, the production period of a ceramic productcan be greatly shortened, the occupied space in the ceramic production process is reduced, and accordingly the single-ceramic producing and manufacturing cost is reduced.
Description
Technical field [0001] The invention relates to the field of ceramic production, in particular to a method for manufacturing a pressed ceramic mold and a ceramic embryo. Background technique [0002] In the traditional ceramic production process, more than 70 processes are required for ceramic materials to make ceramic products. The production process and cycle are too long, especially before the ceramics need to be dried for a long time, which makes a large amount of ceramics. The semi-finished product is in the drying process, which makes the ceramic semi-finished product occupy a large amount of space and space, which not only consumes the space of the workshop for producing ceramics, but also seriously extends the cycle of ceramic production, which greatly reduces the efficiency of ceramic production and therefore improves The cost of ceramic parts production. If a device can be designed that can synchronize the process of making ceramic embryos with the drying process and c...
