[0012] Specific implementation plan

[0013] Such as figure 2 The isostatic pressure forming ceramic pot mold shown in is to tightly sleeve the rubber or polyurethane outer mold 5 at the positioning step 10 of the metal mold core 7, and hollow out the center of the mold core to reduce the weight of the metal mold core 7. 11. Of course, it can also be solid without hollowing out. Remove the rubber or polyurethane bottom mold 4, and add the granulated ceramic powder 6 from the outer mold feed port 12 to the gap between the rubber or polyurethane outer mold 5 and the metal core 7 that is the cavity, and place the upper part The ceramic powder 6 is flattened, and then the rubber or polyurethane bottom mold 4 is plugged into the outer mold feeding port 12, and the filling is completed by plugging. The filled isostatic pressing ceramic pot forming mold can be pressed into a dry bag isostatic press or a traditional wet bag isostatic press.

Abstract

The invention relates to an isostatic pressing forming method of a ceramic inner container and a die of the ceramic inner container. The isostatic pressing ceramic inner container die is filled with granulated ceramic powder, a die core of the inner container die is a metal hard die, and the shape and the size of the die core are consistent with the shape and the size of the inner surface of a inner container blank; an outer die of the inner container die is rubber or polyurethane flexible film, a cavity filled with the ceramic powder is left between the outer die and the die core, and the space size of the cavity is scaled according to the compression ratio of the ceramic powder. The rubber or a polyurethane bottom die is arranged on the upper portions of the die core and the outer die. After the ceramic powder with the required weight is added into the cavity, the powder is scraped, the bottom die is covered, and the die is fed to an isobaric chamber for pressurization. After pressure maintaining and pressure relief, the die is taken out, and a rubber die is taken out to take out the formed ceramic inner container blank.

Description

Technical field [0001] The invention relates to an isostatic pressing forming method and mold for producing ceramic pots, especially suitable for producing high-performance stoneware pots. The pots can be widely used in electric rice cookers, electric soup pots, etc., which require relatively high pot sizes. occasion. Background technique [0002] At present, the known production method of ceramic pot liner is to adopt wet forming: the ceramic raw materials prepared according to different formulas are subjected to wet ball milling-press filtration-mud stale-vacuum mud refining-rolling forming-blank trimming-drying And obtain the pot gall green body, or adopt the method of wet ball milling-grouting method forming to be suitable pot gall green body. [0003] The pot gall body formed by the existing method has high water content, strong body and low density, and the green body takes up a large area for drying, and the production efficiency is low, or a special drying line is r...
