Vertical high-pressure grouting forming machine demolding process

Abstract

The invention discloses a vertical high-pressure grouting forming machine demolding process. The vertical high-pressure grouting forming machine demolding process comprises the following steps that a bottom diemold is subject to diemold splitting, a middle diemold is subject to diemold splitting, a layer board is arranged to be in place, and demolding is carried out. In the demolding step, a PLC controls an outer-diemold pressurization hole of an upper diemold to be connected with an air compressor, an outer-diemold water and gas discharging hole of the upper diemold is closed at the same time, the air compressor blows compression air to the upper diemold through the outer-diemold pressurization hole of the upper diemold, and a water film is formed between the inner surface of the upper diemold and a blank; and the blank falls to the layer board due to the gravity of the layer board, the pressure of the compression air keeps to range from 0.01 Mpa to 0.2 Mpa, and the time lasts for 5 seconds to 15 seconds. By means of the above process, the process can adapt to grouting production of at least three diemolds distributed vertically, defects of the blank can be prevented from generating in the demoling process, the quality passing percentquality yield of the blank is improved, the demolding time can be further shortened, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of ceramic manufacturing, in particular to a demoulding process of a vertical high-pressure grouting molding machine. Background technique [0002] The demoulding method of the ceramic body has experienced the evolution from manual demoulding to automatic demoulding. When demolding by manual means, manual labor is required to lift or push away the mold so that the mold is separated from the green body. The demoulding method is labor-intensive, and it is easy to cause the mold and the body to be too tightly bonded, resulting in difficulty in demoulding and scratching the body, and the demoulding quality cannot be guaranteed. Moreover, the surface of the green body released by the traditional demoulding method is uneven, and it takes a lot of time to process the green body. This leads to problems such as low production efficiency and long production cycle. [0003] In the Chinese invention patent CN104290174 publishe...
