At present, a high-pressure forming process is mostly used for ceramic forming, and particularly in the field of ceramic sanitary ware. The high-pressure forming process is characterized in that in the grouting process, certain pressure is applied to slurry filled into a mold to discharge moisture, so that the slurry is quickly dehydrated and hardened to form a blank, wherein micropores of the mold are used as quick discharge channels of the moisture in the slurry. The resin mold has criss-cross channels formed inside, relatively large pore size, and is suitable for use as drainage channel under high pressure, and has excellent compression and bending resistance, high hardness and high toughness.
In a common high-pressure molding resin mold, a plurality of water passages are formed behind the use surface of the mold, and the water passages correspond to water grooves of a matching mounting substrate below the mold. During high-pressure grouting, water in the slurry flows to the water passage through the micropore channels in the resin to be collected and is quickly discharged from the water passage, so that the efficiency is improved. However, because the aperture of the existing resin mold is too large and the porosity is too low, in practical use, the local micropores of the resin mold are easy to be blocked, poorly drained or damaged due to the entering of slurry, and in order to avoid the situation, some existing ceramic manufacturers generally need to readjust the fineness of the ceramic slurry to match the fineness with the aperture of the mold, so that the blocking of the aperture of the mold is avoided; in addition, some ceramic manufacturers increase the number of times the resin mold is cleaned and maintained, thereby preventing the ceramic slurry from blocking the pore diameter of the mold.
