The present solution provides specific forms of the two forming dies 16, but is not limited to include only the following two forming dies 16.
Form one of the molding die 16:
As shown in fig. 3 to 5, 10 and 11, the upper die set 161 and the lower die set 162 are used for forming the roof tile 19 to form a mortise and tenon hidden-fastening tile wave 191 on the roof tile 19, the upper die set 161 comprises a first upper die 1611, a second upper die 1612 and a third upper die 1613, and the structures of the three are similar to each other and are all strip-shaped structures, and the main difference is that the shapes of the mortise and tenon hidden-fastening tile wave forming grooves formed by the three are different; specifically, a first mortise and tenon joint hidden-button tile wave forming groove 16111 which is concave upwards is formed in the lower end of a first upper die 1611, a second mortise and tenon joint hidden-button tile wave forming groove 16121 which is concave upwards is formed in the lower end of a second upper die 1612, and a third mortise and tenon joint hidden-button tile wave forming groove 16131 which is concave upwards is formed in the lower end of a third upper die 1613; when the first upper die 1611, the second upper die 1612 and the third upper die 1613 are arranged together, the first mortise and tenon joint hidden-button tile wave forming groove 16111, the second mortise and tenon joint hidden-button tile wave forming groove 16121 and the third mortise and tenon joint hidden-button tile wave forming groove 16131 are mutually corresponding and communicated to form a mortise and tenon joint hidden-button tile wave forming composite groove 1614 for forming the mortise and tenon joint hidden-button tile wave 191. The lower mould 162 is located the below of last mould module 161, and the upper end of lower mould 162 is equipped with mortise and tenon joint hidden discount tile ripples shaping piece 1621, and mortise and tenon joint hidden discount tile ripples shaping piece 1621's shape is unanimous with mortise and tenon joint hidden discount tile ripples 191 shape.

When the roof tile 19 is formed, the mortise and tenon joint hidden-button tile wave forming block 1621 upwards props the roof tile 19 in a soft state to form a mortise and tenon joint hidden-button tile wave 191, the upper die module 161 presses the roof tile 19 from above, and the mortise and tenon joint hidden-button tile wave forming composite groove 1614 and the mortise and tenon joint hidden-button tile wave forming block 1621 are matched with each other to form the mortise and tenon joint hidden-button tile wave 191 on the roof tile 19. When the mold is closed, the upper mold module 161 is pressed down and staggered with the lower mold 162, and the upper mold module 161 is all arranged in the gel uncured area of the sizing material, so that the upper mold module 161 is pressed down and closed smoothly when the sizing material is soft and elastic.
An upper die set 161 is formed by combining a first upper die 1611, a second upper die 1612 and a third upper die 1613 which are provided with different mortise and tenon joint hidden-button tile wave forming grooves, so that the first mortise and tenon joint hidden-button tile wave forming groove 16111, the second mortise and tenon joint hidden-button tile wave forming groove 16121 and the third mortise and tenon joint hidden-button tile wave forming groove 16131 form a mortise and tenon joint hidden-button tile wave forming composite groove 1614, and the mortise and tenon joint hidden-button tile wave forming composite groove 1614 and a mortise and tenon joint hidden-button tile wave forming block 1621 are matched to form a mortise and tenon joint hidden-button tile wave 191 for a roof tile 19; in the process, the first mortise hidden-button tile wave forming groove 16111, the second mortise hidden-button tile wave forming groove 16121 and the third mortise hidden-button tile wave forming groove 16131 respectively bear the forming of different positions of the mortise hidden-button tile wave 191, and the three are combined to finally form the mortise hidden-button tile wave 191; therefore, the forming die 16 can be suitable for producing mortise and tenon hidden-fastening tile waves 191 with small opening parts, large inside and complex shapes; the special shapes of the first mortise hidden-button tile wave forming groove 16111 and/or the second mortise hidden-button tile wave forming groove 16121 and/or the third mortise hidden-button tile wave forming groove 16131 can be flexibly set according to the shapes of the mortise hidden-button tile waves 191 to be formed, or on the basis of producing different first upper dies 1611, second upper dies 1612 and third upper dies 1613, the upper die modules 161 can meet different production requirements through the combination of the three; on the other hand, the upper die set 161 and the lower die set 162 are staggered, so that the problem that the mortise and tenon hidden-fastening tile wave forming block 1621 and the mortise and tenon hidden-fastening tile wave forming composite groove 1614 are clamped during die assembly is avoided.
