Definitions

  • This invention relates generally to the bending or shaping of glass sheets or plates to a desired configuration, and more particularly to an improved bending mold for bending glass sheets.
  • the shaping rails are ground to the exact contour to which the glass sheet is to be bent and in the areas of the abutting ends of the sections adjacent the hinges the rails are ground and matched so that there is a substantially continuous, smooth glass shaping surface.
  • the object of the present invention to provide an improved bending mold which is easily assembled and which has readily adjustable shaping surfaces.
  • Another object of the invention is to provide a multiple section bending mold in which individual sections may be easily replaced.
  • a further object of the invention is to provide a multiple section hinge type bending mold in which sections of the shaping rail may be installed or replaced without grinding to blend at the hinge joints.
  • FIG. 1 is a front elevation of the improved mold and frame
  • FIG. 2 is a plan view of the mold and frame of FIG. 1;
  • FIG. 3 is an enlarged elevation with parts in section of the improved hinge structure as viewed from the center of the mold;
  • P16. 4 is a section of the hinge construction taken on the line 4-4 of FIG. 3;
  • FIG. 5 is another section of the hinge construction taken on the line 5-5 of FIG. 3.
  • the numeral refers to a mold supporting frame which is comprised of a pair of longitudinally extending base members 11 held in substantially parallel, spaced relationship by a pair of spaced transverse skids or rails 12.
  • the rails 12 also serve to guide the rack as it moves along a conveyor (not shown) through a bending furnace.
  • Four vertically extending hanger posts 13 are secured to the base members 11 near the longitudinal extremities thereof.
  • a mold generally indicated by the numeral 14 is carried by the hanger posts 13 and includes a center section 15 which is comprised of a pair of substantially parallel 3,@Z3,543 Patented Mar. 6, 1962 relatively long spaced shaping rails 16 bent to a relatively long radius. Shaping rails 16 are held in spaced relationship by cross rods 17 secured to the inwardly facing surfaces of the inverted T sections which form the shaping rails.
  • the center section 15 is movably connected to oppositely disposed aligned rectangular end sections 18 each of which comprises shaping rails 19 which are also formed by inverted T sections.
  • End section shaping rails 19 are bent sharply upward from the point of juncture between the center section 15 and the end sections 18 as viewed in FIG. 1.
  • the top edge of the shaping rails 16 and 19 join in their closed position to form a continuous substantially uninterrupted shaping surface A.
  • the end section shaping rails 19 are reinforced by cross rods 20 which are mounted in the same manner as center section cross rods 17.
  • pairs of depending arms 21 are welded or fastened by other means to the outwardly facing surface of each end section shaping rail 19 on opposite sides thereof about midway between the ends.
  • Each arm 21 carries a pin 22 at its lower extremity which pivotally engages the lower end of a link 23, which, in turn, is pivoted at its upper end about a pin 24 extending through a corner post 13 near the upper extremity thereof.
  • Hinges 25 join the center section 15 with the end sections 18.
  • the hinges 25 are mounted on the mold by means of new and novel structure which facilitates easy assembly and disassembly of the mold and which permits individual mold sections to be easily replaced.
  • the center rails 16 are notched at the bottom corners on both ends, leaving the top or shaping surface intact.
  • a rail plate 26 is tack welded as at 27 to overlie a portion of the notch B on the inwardly facing surface of the shaping rail 16. In order that the hinge 25 may retain the shaping rails in proper alignment the rail plate 26 is substantially parallel to the shaping rail 16.
  • the outermost edge of the rail plate 26 lies inwardly of the outermost end of both the notched out portion B and the shaping rail 16 in order to prevent the mold from binding during closure.
  • An integrally formed leg portion 28 extends downwardly from the rail plate 26 and an aperture 29 extends through the rail plate 26 at a point directly above the leg 28.
  • a generally L shaped lug 30 is secured to the outwardly facing surface of the rail plate 26 parallel to the shaping surface of the center section shaping rail 16.
  • the lug 30 terminates in the longitudinal direction a short distance from the edge of the rail plate 26 which lies adjacent the outermost end of the rail 16, while the opening between the L shaped lug 30 and the rail plate 26 provides a vertical slot 31 adjacent and extending parallel to the outwardly facing surface of the rail plate 26 directly beneath the center section shaping rail.
  • the hinge 25 includes a clevis portion 32 comprising a vertically extending rib 33 disposed at right angles to the adjacent end rail section and parallel spaced bifurcations 34 and 35 secured thereto which extend toward the transverse center line of the mold 14 at right angles to the rib 33.
  • the bifurcations 34 and 35 contain aligned apertures 36 at the lower innermost corners.
  • the lower innermost corners of the end section shaping rails 19 are notched at C to receive the rib section 33 of the clevis portion 32 which is tack welded to the end rails at 37 in abutting relation with the notched portion C.
  • the bifurcations 34 and 35 are each positioned within the notched portion C and are spaced equidistant from the plane of each end shaping rail 19.
  • the hinge 25 also includes an eye portion 38 that is provided with an aperture 39 which when aligned with the apertures 36 in the clevis portion 32 is pivotally joined to the clevis portion 32 by a hinge pin 40. Lateral movement of the hinge pin 40 in the aligned apertures is prevented by a washer 41 mounted opposite the head end of the hinge pin 40 and secured by a cotter key 42. To limit the closing motion of the mold 14 a stop member in the form of a projection 43 is provided near the top of the eye portion 38 and is adapted to contact the rib $3 of the clevis portion 32.
  • the hinge plate 44 tack welded thereto at several points indicated by the numeral 45.
  • the hinge plate 44 carries a pivot pin 46 substantially in the center thereof adapted to extend through the aperture 29 in the rail plate 26 to permit the hinge plate to pivot thereabout.
  • the hinge plate 44 extends upward and is received in the vertical slot 31 where it is confined in final assembly against lateral movement to prevent disengagement of the pivot pin 46 from the aperture 29.
  • Locator pins 47 and 48 are carried by the hinge plate 44 below the pivot pin 46 and as seen in FIGS. 3 and these locator pins 47 and 48 project inwardly from hinge plate 44 parallel to the pivot pin 46.
  • a mold comprising a plurality of sections including an end section and an intermediate section having shaping surfaces formed thereon, said mold sections adapted to move relative to each other to a position wherein said shaping surfaces form a continuous surface defining the configuration to which the glass sheet is to be bent, hinge means mounting said end section for rotative movement to said position, and adjusting means connecting said hinge means with said intermediate section, said adjusting means comprising a first member rigidly secured to said intermediate section and a second member rigidly secured to said hinge means, and means pivotally connecting said first member and .said second member to permit said first member to rotate relative to said second member thereby changing the relative position of the shaping surface of said intermediate section and said end section.
  • Apparatus for selectively connecting and disconnecting adjacent sections of a glass bending mold and aligning the glass engaging shaping surfaces formed on said sections comprising a hinge having two hinge members pivotally joined together with one of said members secured to the end of one of said sections, a plate secured to the other of said hinge members and extending toward the end of anladjacent section of said bending mold, a second plate secured to the end of said adjacent section and overlapping said first member, means pivotally connecting said first and second members for movement with respect to each other about a fixed axis thereby to shift the glass engaging surfaces formed on said sections relative to each other, and locating means formed on said first plate and said second plate, and adjustable clamping means acting between said locating means on said first plate and said second plate to prevent relative rotation between said first and second plate.
  • a mold comprising a plurality of mold sections including an end section and an intermediate section having shaping surfaces formed thereon, said mold sections adapted to move relative to each other between an open, sheet receiving position and a closed position wherein said shaping surface forms a continuous surface defining the configuration to which the glass sheet is to be bent, a hinge having a clevis portion secured to said end section and an eye portion, a hinge pin pivotally connecting said eye portion and said clevis portion, adjustment means connect- .ing said intermediate section to said eye portion whereby said end sections swing about said hinge pin as an axis between said open and closed positions, said adjustment means comprising a first member secured to said eye portion and projecting toward said intermediate section, spaced apart pins secured at one end to said first member and projecting laterally outwardly therefrom, a second member rigidly secured to said intermediate section, a pivot pin joining said first and second members and extending parallel to said hinge pin whereby said first and second members rotate about said pivot pin as an axis to alter the relative positions of
