Abstract

The invention relates to a hollow ceramic die which is provided with a cavity, one end of the cavity is provided with a pouring portion with a pouring port, the other end of the cavity is provided with an air inlet portion with an air inlet, and an air valve is arranged at the air inlet. The invention further relates to a forming method of hollow ceramic through the hollow ceramic die. The hollow ceramic die is simple in structure, residual stress of a blank body can be reduced effectively, and the manufactured hollow ceramic blank body is mellow and full; meanwhile, the precision hollow ceramic products such as spiral hollow ceramic blank bodies which can not be manufactured through conventional methods can be manufactured; the hollow ceramic component manufactured through the forming method of the hollow ceramic component has high precision, the forming method can be applied to the field of precision ceramics, the blank manufacturing period is shortened, the production efficiency is improved, and production raw materials are saved.

Description

technical field

[0001] The invention relates to the field of ceramic molds, in particular to a hollow ceramic mold and a method for forming a hollow ceramic component. Background technique

[0002] In the prior art, there are generally two manufacturing methods for hollow ceramic components with relatively complex shapes, such as a section of elbow, a section of spiral elbow, a section of Y-shaped elbow, or other ceramic components with irregular channels. One is to use the traditional method of grouting and dehumidification of plaster molds to form channels, which is suitable for ceramic components that do not require high molding precision; the other method is to use some organic materials to make connections according to the shape of channels Core parts, use core pulling to fix the connecting parts in the finished mold, and then inject ceramic slurry to make the green body. Before firing, the connecting core parts are eroded by physical or chemical methods to make the req...

Examples

Embodiment 1

[0038] 1. The structure when the cavity of the hollow ceramic mold is U-shaped.

[0039] see figure 1 , the cavity of the hollow ceramic of the present embodiment is a U-shaped cavity, and the mold is a clamping mold, which forms a U-shaped cavity after clamping the molds. One end of the U-shaped cavity is provided with a pouring part 1, and the pouring part 1 is opened. There is a pouring port 11, and the other end of the U-shaped cavity is provided with an air inlet 2, and the air inlet 2 has an air inlet 21, and a core pulling 3 is installed on the air inlet 21, and the core pulling 3 has an outer screw The core-pulling 3 has a cylindrical through-hole 31 in the center of the core-pulling axis, and an air valve 22 is installed in the cylindrical through-hole. The air end faces the outside of the mould, the air intake end of the air valve 22 is connected with an air intake pipe, and the air intake pipe is connected with an external air intake device.
