Mould for manufacturing a multi-curved belt glass panel
The invention relates to the mold ( 1 ) for manufacturing a multi-curved bent glass panels comprising a stationary lower load-bearing structure ( 2 ) having defined longitudinal ( 2 a ), a transversal ( 2 b ) directions and vertical direction ( 2 c ) and provided with a supporting frame ( 4 ) and a number of contoured supports ( 5 ) mounted in the supporting frame ( 4 ) in the vertical and parallel arrangement to each other and having its upper edges shaped in waves; wherein the supports ( 5 ) are arranged in such an order, that their upper edges form a predetermined bending surface, curved along at least one of the longitudinal ( 2 a ) and transversal ( 2 b ) directions and alternately upwards and downwards in the vertical direction ( 2 c ), having variable curvature and the depth of the curve.
1. A mold ( 1 ) for manufacturing a multi-curved bent glass panels comprising:
a stationary lower load-bearing structure ( 2 ) provided with:
a supporting frame ( 4 ); and
a number of supports ( 5 ) are removably mounted in the supporting frame ( 4 ) in the vertical and parallel arrangement to each other; and
an upper load-bearing plate ( 3 ) being located on the supports ( 5 ) of the stationary lower load-bearing structure ( 2 ) for supporting a glass panel ( 6 ) being formed wherein
the supports ( 5 ) of the lower load-bearing structure ( 2 ) have its upper edges shaped in waves and the supports ( 5 ) are arranged in series parallel to each other in such an order, where their upper edges form a predetermined bending surface, curved glass panel, wherein
the upper load-bearing plate ( 3 ) is a plate susceptible to deformation under the influence of the temperature, placed on the mentioned upper edges of the supports ( 5 ) and it is covered with separation substance, wherein the upper load-bearing plate ( 3 ) may optionally comprise an underlay glass panel ( 3 a ), covered with separation substance, where the supporting frame ( 4 ) comprises longitudinal beams ( 4 a ) characterized in that longitudinal beams ( 4 a ) are provided with series parallel to each other retaining elements ( 4 b ) projecting upwardly, which are suitable for maintaining the supports ( 5 ) in a predetermined vertical position, wherein the distance between adjacent retaining elements ( 4 b ) corresponds to the thickness of the supports ( 5 ) where the lower edge of each support ( 5 ) is inserted between the two retaining elements ( 4 b ) in each series of retaining elements ( 4 b ).
2. The mold according to claim 1 , characterized in that the supports ( 5 ) are spaced apart in the lower load-bearing structure ( 2 ) at intervals of 1 to 3 cm from each other.
3. The mold according to claim 1 , characterized in that the supports ( 5 ) are made of refractory material.
4. The mold according to claim 3 , wherein the supports ( 5 ) are made of refractory ceramics.
