Abstract

PROBLEM TO BE SOLVED: To obtain a molding completely corresponding to a mold for molding by providing air bleeding holes corresponding to a protrusion and recess part and step part formed on a molding surface of the mold, thereby bleeding the air retaining corners of the protrusion and recess part and step part. SOLUTION: When a tile ground W on a molding surface of a lower mold 3 of a mold 1 for the clay tile is pressed by an upper mold 2, the air of protrusion and recess parts 8, 8a,... of molding surfaces 6, 7 is exhausted from air bleeding holes 9, 9a,... under pressure at the time of pressing. And, even if clay scrap of the ground W is introduced into the holes 9, 9a,..., the clay scrap is discharged together with the air exhausted under pressure generated at the time of press molding of next time from the holes 9, 9a through pipelines 13, 13a and discharged externally through the pipelines 13, 13a at the time of cleaning the mold 1 or the like. Thus, the scrap is stored in removed parts 12 so as not to block the holes 9, 9a. Accordingly, the ground can be filled in the overall protrusion and recess part to obtain the molding completely corresponding to the molding surface.
