Description

  The present invention relates to a method for manufacturing a tile such as a left and right faced roof tile.

  Usually, in the mold structure for molding a clay tile in which a cavity is formed by an upper mold and a lower mold, it is necessary to set an upward or downward draft. In forming the left and right faced roof tiles with the rising portions, the rising portions are, for example, as shown in FIG. I want to make it perpendicular to the horizontal plane LL. In addition, it is desirable that the face door part has the surface bb as an elevation angle with respect to LL and guides rainwater to the eaves side.

  Incidentally, as shown in FIG. 14-2, when the draft angle is applied and the mounting surface a′-a ′ is set to an elevation angle, the surface door portion surface b′-b ′ inevitably becomes a depression angle. The upper mold is caught. Further, when the face door portion surface b'-b 'becomes a depression angle, the problem remains that the lower mold is caught and it is difficult to remove the mold.

  A possible countermeasure is the molding method shown in FIG. 15. This molding method is disclosed, for example, in Japanese Patent Application Laid-Open No. 2003-301564, “Face-to-door tile, glazed roof tile, and roof tile structure”. It is applied to single-sheet molding of facing tiles with facing doors (referred to as reference (1)).

  However, in this example, all the surfaces of the rising portion, the funnel portion, and the face door portion are inclined, and the mold structure is complicated and maintenance is complicated. In addition, the joints (corners) on each surface become weirs, impeding the flow of clay and causing imbalance in molding density, and it is also difficult to take measures against air trapped in main corners, mountains or valleys. It is difficult to secure the shape and / or accuracy of the part, which is technically difficult. Furthermore, due to the above-mentioned problems related to the draft angle, it is one of the obstacles that it is limited to one-piece molding and that the form after demolding is unstable and a large number of dedicated jigs are required, which is preventing the spread. There are issues to be solved.

  In a case different from the above-described example, examples of the method shown in FIGS. 16 and 17 are conceivable as a method of connecting and integrating the right and left tiled roof tiles at the end of the face door and simultaneously forming them. In this case, in order to form an effective rising portion, a groove having a rectangular cross section having an effective height and width that can stably fix the rising portion to the base material is formed in the uppermost central portion of the upper mold over the entire width of the clearance. It is necessary to drill with high accuracy. This measure entails considerable difficulty in designing and producing molds, and is difficult to maintain, and air traps that occur during press molding are hindered, making it difficult to ensure the required shape and / or accuracy. It is known that many problems remain. In addition, this side-to-side glazed tile with face doors needs to accurately divide the rising part at the center dividing line and smooth the contact surface with the base material before construction. Technical skill and time are required and practicality is considered to be poor. The glazed roof tiles with face doors shown in this example are disclosed in Japanese Patent Application Laid-Open No. 2004-183234 as “a roof tile with a face door for ridges and corner ridges”, or “climbing drained tiled roof tiles with face doors” of Japanese Patent Application No. 2003-314154. It is disclosed (referred to as documents (2) and (3)).
