Definitions

  • FIGURE 5 is a sectional view taken through the mold ring along the direction of line 5-5 in Figure 4 and illustrates the manner in which an upper flat portion of the mold ring supports the glass sheet upon initially being received by the mold ring.
  • FIGURE 6 is a view similar to Figure 5 but taken after the forming to illustrate a relief portion of the mold ring contoured surface that is spaced from the adjacent glass sheet edge portion inwardly of the glass line.
  • FIGURES 7 and 8 are views similar to Figure 6 but illustrating different constructions of the contoured surface of the mold ring.
  • mold ring 34 as described above permits forming of glass sheets without edge portion deformation.
  • This forming mold has particular utility when the mold ring 34 has a unitary construction with its contoured surface 40 fixed at the design shape as opposed to articulated molds where mold portions pivot with respect to each other.
  • the relief portion 44 of the contoured surface 40 of the mold ring 34 defines an angle ⁇ in the range of 5 to 20° with the adjacent edge portion 46 of the design shape of the glass sheet edge portion 48.
  • This angle ⁇ most preferably is in the range of 8 to 15°.
  • the mold ring 34 of the forming mold 20 has an elongated shape including opposite ends 50 that have the upper flats 48 for respectively initially supporting opposite ends of an elongated heated flat glass sheet upon being received by the mold ring for the forming to the design shape. While the elongated direction of the forming mold 20 has been shown extending along the direction of conveyance C for ease of illustration, most elongated molds will have their elongated directions extending transversely to the direction of conveyance in actual production jobs .
  • the contoured surface 40 extends downwardly from the upper flat 48 with the designed shape of the formed glass sheet edge portion 46 but is rotated about the glass line 42 in a counterclockwise direction by the angle ⁇ defined with the relief portion 44.
  • the contoured surface is above and inward of an extension of the lower surface of the formed glass sheet edge portion 46.
  • the contoured surface 40 outside of the glass line 42 is a continuation of the design shape of the lower surface of the adjacent glass sheet edge portion 46 and the relief portion 44 is relieved from that design shape by the angle a as previously described.
  • the contoured surface 40 outside of the glass line 42 is a continuation of the design shape of the lower surface of the adjacent glass sheet edge portion 46. Furthermore, the contoured surface 40 extends inwardly from the glass line 42 about three or four millimeters with the design shape of the lower surface of the glass sheet edge portion 46 and inside thereof the relief portion 44 defines the angle .
  • This construction works best with glass sheets where the edge portion is partially covered to hide any distortion that results from the support provided for the glass sheet edge portion 46 inside of the glass line 42.
  • the forming mold 20 has rounded opposite ends 50 as shown, the mold may have a more rectangular shape with four corners.

Abstract

L'invention concerne un moule (20) pour la formation de plaque de verre. Ce moule comprend un cadre (32) qui soutient un anneau de moulage périphérique (34) à forme profilée (38) présentant une surface profilée (40), pour la réalisation de plaque de verre thermoformée. A l'intérieur d'une ligne de modelage du verre (42) sur la surface profilée de l'anneau de moulage (40), une partie en relief (44) est espacée de la forme modelée de la plaque de verre thermoformée. A l'extérieur de la ligne en question (42), la surface profilée de l'anneau de moulage (40) comporte au moins une partie supérieure plate (48) permettant un contact initial avec la plaque de verre thermoformée avant l'opération de formation.
