Further, the demolding groove and the demolding block are respectively of a circular groove structure and a circular disc structure, and the demolding block is matched in the demolding groove.

Further, the height difference of the outer top block and the inner top block is equal to the depth of the forming groove, so that the outer top block and the inner top block can be ensured to be capable of blocking the top orifices of the outer through hole and the inner through hole at the same time.

Furthermore, the number of the demoulding grooves is four, and the demoulding grooves are symmetrically arranged around the perforated column.

Furthermore, the number of the outer through holes and the number of the inner through holes are four, and the outer through holes and the inner through holes are symmetrically arranged on the periphery of the notch of the forming groove on the lower die and the periphery of the open pore column on the bottom of the forming groove respectively.

Has the advantages that: compared with the prior art, the demoulding member composed of the demoulding block, the outer ejecting block and the inner ejecting block can synchronously and automatically eject the ceramic product blank in the forming groove through the inner ejecting block after the upper mould is separated by utilizing the upward elasticity of the spring member, so that the ceramic product blank is conveniently clamped and taken out, the demoulding efficiency is improved, the ceramic product blank is ensured to be taken out at one time, and the ceramic product blank is prevented from being damaged.
