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 mold for pressing ceramics 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 post structure 5 . The upper mold fixed plate 1 is located on the top of the pressed ceramic mold, the punch 2 is fixed on the bottom of the upper mold fixed plate 1 through the upper connecting block 11, the punch 2 is matched in the through hole in the center of the upper connecting block 11, and the upper connecting block 11 The surface is connected with the upper die fixed plate 1 through the connecting rod, the upper end of the punch 2 is slidingly matched with the groove on the lower surface of the upper die fixed plate 1, and the stamping part of the punch 2 (the part that directly squeezes the ceramic material) The profile is consistent with the cavity structure of the pressed ceramic part 9 (open vessel, such as teacup, bowl, etc.). The lowe...
Embodiment 2
[0049] According to another aspect of the present invention, a method for making a ceramic embryo is disclosed, comprising the following steps:
[0050] S1. Prepare ceramic raw materials with a water content of 3.5% to 5.5%;
[0051] S2. Add a certain amount of ceramic raw material with a water content of 3.5% to 5.5% into the pressing groove 41 of the pressing ceramic mould;
[0052] S3. The punch 2 presses the ceramic raw 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. Putting the pressed ceramic embryo into a calciner for calcination, cooling and taking out the ceramic embryo after the calcination is completed.
[0055] Among them, the solid content of ceramic raw materials is: clay 10%-20%, quartz 15%-23%, feldspar 5%-8%, kaolin 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%, Si3N40.8%-1.2% %, ZrO2...

Abstract
The invention discloses a method for manufacturing a pressed ceramic mold and a ceramic embryo, belonging to the field of ceramic production. The pressed ceramic mold includes an upper mold fixing plate, a punch, a lower mold fixing plate, a lower mold module, and a guide post structure. The punch is fixed on the bottom of the upper mold fixing plate through the upper connecting block, and the shape of the stamping part of the punch is consistent with the inner cavity structure of the pressed ceramic part. The lower mold module is fixed above the lower mold fixing plate, and the upper surface of the lower mold module is provided with a pressing groove, and the structure of the pressing groove is consistent with the structure of the outer surface of the pressed ceramic part. The guide column structure is used to make the punch move up and down with the upper connecting block, and when it is in the mold clamping state, the cavity formed between the stamping part of the punch and the pressing groove of the lower die module The structure is the structure of the pressed ceramic part. The pressed ceramic mold disclosed by the invention can greatly shorten the production cycle of ceramic products and reduce the space occupied in the ceramic production process, thereby reducing the production cost of a single piece of ceramics.
Description
technical field [0001] The invention relates to the field of ceramic production, in particular to a method for making a pressed ceramic mold and a ceramic embryo. Background technique [0002] In the traditional ceramic production process, it is necessary to carry out more than 70 processes on ceramic materials to make ceramic products. The production process and cycle are too long, especially before the ceramics are fired for a long time, which makes a large amount of ceramics The semi-finished products are in the drying process, so that the ceramic semi-finished products occupy a lot of space and space, which not only wastes the space of the workshop for producing ceramics, but also seriously prolongs the cycle of ceramic production, which greatly reduces the efficiency of ceramic production, so it is improved. The cost of ceramic parts production is reduced. If a device can be designed to synchronize the embryo making and drying process of ceramics and complete it quickl...
