Description

Technical Field

[0001] The utility model relates to the technical field of sintering molds, in particular to a ceramic sintering graphite mold with a demoulding function. Background Art

[0002] When using a graphite mold to sinter ceramic powder under high temperature and high pressure conditions, the powder shrinks under the action of temperature and pressure and squeezes outward from the mold. The mold needs to withstand greater pressure. Too much pressure will cause greater friction between the fired ceramic sample and the inner wall of the graphite, causing the product to stick tightly to the graphite mold, affecting the subsequent removal of the product. The mold often needs to be knocked to remove the product, which poses a risk of damaging the mold. In addition, the innermost mold may break due to excessive adhesion, resulting in increased costs.

[0019] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0020] refer to Figure 1 to Figure 4 The ceramic sintered graphite mold with demolding function includes an outer graphite mold part 1, an inner graphite mold part 2 sleeved on the outer graphite mold part 1, and a demolding component arranged above the outer graphite mold part 1. The inner graphite mold part 2 is separated from the outer graphite mold part 1 by arranging the demolding component. The demolding component is detachably connected to the outer graphite mold part 1. When separation is required, the demolding component is connected to the outer graphite mold part 1. After demolding is completed, the demolding component can be removed without affecting the next use of the outer graphite mold part 1 and the inner graphite mold part 2.

[0021] The demoulding assembly includes a demoulding member 3, on which a plurality of connecting members are provided, and the connecting members are used to connect the demoulding assembly with the outer graphite mold member 1;

[0022] The demoulding member 3 is provided with a central screw hole 7 and a plurality of first screw holes 8. The upper side wall of the outer graphite mold member 1 is provided with connecting screw holes 6 that match the first screw holes 8.
