Embodiment Construction

[0015] Below in conjunction with accompanying drawing and embodiment the technical solution of the present invention is further described:

[0016] Such as figure 1 As shown, the present invention provides a special mold for direct pressure molding of sanitary ceramic blanks, including a male mold 1 and a female mold 2 that cooperate with each other. The male mold 1 and the female mold 2 are composed of water-absorbing and breathable K-type gypsum. 1 and the side wall of the female mold 2 are provided with two upper and lower steel mold sets 3 that constrain their deformation, and the two steel mold sets 3 are concave inward at their joints to the edge of the cavity formed by the male mold 1 and the female mold 2, And the vertical side walls of the two steel mold sets 3 are provided with a support block 31, and the upper and lower walls of the male mold 1 and the female mold 2 are connected to the mold steel seat 7 of the hydraulic equipment through the gasket, so when the mol...

Abstract

The invention belongs to the technical field of ceramic forming and in particular relates to a forming mold of a bathroom ceramic blank. The forming mold comprises a male die and a female die, which are matched with each other. The forming mold is characterized in that: the male die and the female die consist of water-absorbable and air-permeable K gypsum; steel mold sleeves are arranged on side walls of the male die and the female die and restrain the deformation of the side walls; and air inlets which are communicated with compressed air are arranged on the steel mold sleeves. By adoption of the technical scheme of the invention, the mold for direct-pressing forming of the bathroom ceramic blank is high in intensity, water-absorbable and air-permeable, and facilitates de-molding of the blank.

Description

technical field [0001] The invention belongs to the technical field of ceramic molding, and in particular relates to a molding die for sanitary ceramic blanks. Background technique [0002] In the field of sanitary ceramics, the production of ceramic blanks usually adopts the grouting molding process. The grouting molding process requires the mold to absorb the moisture in the slurry to make the slurry form a crust. Therefore, the molding speed is slow. After each grouting molding, the mold needs to be repaired. Dry, unable to work continuously, low efficiency. [0003] In view of the shortcomings of the grouting molding of the existing sanitary ceramic blanks, the inventor invented the blank direct pressure molding process, which is used to make blanks with large openings, such as water tanks, water tank covers, squatting pans, wash basins, etc. The specific process is as follows: according to the configuration Comparing with the configuration of the molding material, add ...
