Embodiment 1

[0007] Embodiment 1: A ceramic slurry pouring and grouting forming method, comprising the following steps: setting the grouting head of the grouting pipe vertically upward, sealing the grouting hole at the bottom of the plaster mold with the vertically upward tank grouting head to make the grouting The slurry is injected into the cavity of the plaster mold from bottom to top. There is a small air hole with a diameter of 2mm on the top of the plaster mold. Iron nails are inserted in the small air holes. The iron nails prevent the ceramic mud from overflowing and can run out of air. The ceramic mud passes through The high-pressure grouting machine uses pressure to inject the mud into the plaster mold. Before the cavity is filled to 1 / 2, the grouting pressure is controlled at 1.5 kg. After the cavity is filled to 1 / 2, the pressure is gradually weakened until the mold Fill the cavity, keep the pressure until the green body on the inner wall of the cavity reaches the required thickn...

Abstract

Provide is a ceramic slurry reverse-pouring grouting molding method. The method comprises the following steps that a grouting head of a slurry conveying pipe is arranged vertically and upwards, a grouting hole in the bottom of a plaster mold is in butt joint with a vertically upward grouting head in a sealed mode, a grouting fluid is made to be injected into a mold cavity of the plaster mold from bottom to top, a small air hole is formed in the top of the plaster mold, and an iron nail is inserted into the small air hole, wherein the iron nail enables ceramic slurry to be prevented from overflowing and can achieve air releasing; the ceramic slurry can be injected into the plaster mold through a high pressure grouting machine with pressure, before half of the mold cavity is filled with the slurry, the grouting pressure is controlled to range from 1 kg to 1.5 kg, and after half of the mold cavity is filled with the slurry, the pressure is weakened slowly till the mold cavity is filled up; the pressure is kept till a green body of the inner wall of the mold cavity reaches the needed thickness, the pressure is relieved, the iron nail on the top of the plaster mold is pulled out, the ceramic slurry flows out completely and freely, after the green body in the mold cavity of the mold is dried and shrinks, demolding is conducted finally, and when demolding is conducted, the small air hole left by the iron nail is filled with same dry ceramic.

Description

technical field [0001] The invention relates to a ceramic mold grouting forming method. Background technique [0002] At present, in the field of ceramics, grouting is a relatively common large-scale production method in the industry. The traditional grouting process adopts the process of positive injection. Evenly, it adds a certain degree of difficulty to post-production and product quality control. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a ceramic slurry reverse injection grouting molding method which can effectively ensure uniform thickness and uniform color of the whole green body and greatly reduce subsequent reprocessing time. [0004] In order to achieve the purpose of the present invention, the following technical solutions are provided: a ceramic slurry reverse injection grouting molding method, which is characterized in that it includes the following steps: setting the grouting head of the g...
