The present invention relates to a method for producing a pressure casting mold which is improved so as to prevent air leakage of the above.

型を分離して成形品を取り出すというものである。[Prior Art] Pressure casting mainly adds pressure when performing drainage casting, and is widely used today as a method for manufacturing sanitary ware such as toilet bowls and washbasins.
The casting method by pressure casting is summarized as follows: By injecting sludge (powder-like kneaded clay for forming into a mud shape) into the molding space formed in the molding die and pressurizing it, it becomes unnecessary. The liquid content (for example, water) is allowed to penetrate into the molding die, and the remaining powdery and granular kneaded material is allowed to infiltrate the inner surface of the molding die, excess slurry is discharged from the molding die, and then the molding die is separated. To take out the molded product.

ては、上型５と下型６とに分離可能になっている。A molding die used for this pressure casting is shown in a side sectional view in FIG. The molding die 1 shown is for casting a washbasin, and the blank part in the die is the molding space. The molding die 1 is formed by polymerization from the molding space side by the filtering material 2 and the pressure-resistant frame 4, and the entire die is separable into an upper die 5 and a lower die 6. There is.

りする多孔質チューブ７が埋設されている。The filtering material 2 is made of a porous synthetic resin (or gypsum), and the pressure resistant frame 4 is made of an iron plate or the like. In the filter material layer 2, water in the slurry is removed by suction at the time of casting, or water is supplied under pressure to form a water film on the molding surface 2a at the time of demolding the molded product. The porous tube 7 is embedded.

が不均一になることもあった。[Problems to be Solved by the Invention] In the conventional mold for pressure casting, it is easy for the pores in the filter medium 2 to communicate with the atmosphere through the interface between the filter medium 2 and the pressure-resistant frame 4. Therefore, for example, even if the inside of the tube 7 is depressurized at the time of infiltration, the atmosphere enters the filter medium 2 through the gap between the pressure frame 4 and the interface between the pressure frame 4 and the filter medium 2, and There is a case where the pressure reaches the tube 7 after permeating through and the sufficient pressure reduction for inking cannot be obtained. In addition, the thickness of the inking material becomes extremely thin in the vicinity of the place where the air inflow is strong, and on the contrary, the attention is promoted in the vicinity of the place where the air inflow is not intense. Sometimes became.

着肉成形物に変形や亀裂、破損が生じ易い。Also, when water pressure or air pressure is applied to the inside of the tube 7 during demolding, this pressure may flow in the opposite direction to leak to the atmosphere, and it may be difficult to demold. In this case, when the pressure is high, the infiltration material remains attached to the filter medium 2 in the vicinity of the location where the pressure leakage is severe, and in the vicinity of the location where the pressure leakage is small, the infiltration material largely swells in the direction of peeling from the filtration material. Uneven mold release phenomenon occurs
Deformation, cracks and breakage are likely to occur in the molded product.
