Abstract
The utility model relates to a bended glass plate forming mould which comprises a base, a pre-forming frame and a forming frame. Forming long sides are respectively and fixedly supported on a supporting seat via a pair of supporting posts, the middle of each of the forming long sides are broken, a position corresponding to the broken positions of the forming long sides are broken in the vertical direction of the supporting seat, two broken halves of the supporting seat are pivotally connected, and the forming frame can be raised to a position which is higher than the pre-forming frame and be lowered to a position which is lower than the pre-forming frame by a lever. The structure avoids a scallop which results from the large local deformation of the glass plate because a traditional mould is formed once by self weight, improves the optical performance of the glass plate and lightens mould trace. The middle part of a big head of the forming frame is provided with a hinge. The utility model has the advantages of simple structure and convenient operation. The utility model uses the lever to control the forming frame to be raised and lowered, with simple operation and maintenance convenience.
Description
[technical field]
The utility model belongs to the sheet glass manufacture field, particularly a kind of Glass bending mold.
[background technology]
Traditional shaping glass sheets method be with glass sheet support on curved frames or mould, the gravity by sheet glass self carries out bending, thereby forms the net shape of sheet glass.The moulding of this kind gravity has the border structure approaching with the final curved shape of sheet glass with bending mould.Sheet glass is placed in substantially horizontal mode on the periphery of frame of bending mould, the sheet glass of Zhi Chenging generally divides several formative stages according to differing temps by a bending furnace by this way.First stage is generally the preheating zone, be heated to temperature at the preheating zone sheet glass near the sheet glass softening temperature, the next stage is a shaping area, sheet glass is heated to 560 ℃-650 ℃ temperature there, the bending gradually owing to action of gravity then, sheet glass is complementary to reach desired curvature in the shape of periphery place and framework, and the last stage is the annealing cooling zone, sheet glass is annealed cooling, thereby just they can be removed from forming mould when leaving bending furnace.
The above-mentioned glass bending forming mould that is used for generally comprises a pedestal and a shaping frame, this shaping frame can be the framework of an overall fixed on this pedestal, also can comprise a pair of decide moulding limit and a pair of moving moulding limit, decide the moulding limit and be fixed on the pedestal long limit as this shaping frame, moving moulding limit by hinge with should to decide the moulding limit hinged, as the minor face of this shaping frame, and should moving moulding limit fix a balance flank that has a weight.The middle part is by decide the moulding edge forming when brake forming for big sheet glass, and the two ends sheet glass is after softening, and under the cooperation of weight, flank drives moving moulding limit and makes progress the continuous brake forming of sheet glass gradually around pin joint.
The mould of said structure can cause following problem in the sheet glass process of producing big radian, big sphere: 1. mold-mart is obvious: for the bigger sheet glass of sinuousness, big many of the size of its development size after than bending, therefore when sheet glass last slice, the contact position of glass and mould is just far apart from glass plate edge, like this when sheet glass softens moulding, sheet glass is just very long by the distance that the contact position slides into the edge, thereby cause the large-area slip vestige of sheet glass, influence the visual appearance of sheet glass; 2. the goodness of fit is uncontrollable: for the bigger sheet glass of side camber, length direction arch height ratio, easily produce flounce at the side of sheet glass, this has influenced the entrucking performance of sheet glass; 3. the sheet glass that the side sphere is big can't moulding: when the side sphere is very big, in the crooked initial stage, this part need be protruded greatly, when sheet glass is placed on the mould, the convex part sheet glass does not support because of having, sheet glass is softening when bending, and meeting is under the action of gravity of self, and is sagging to the opposite direction of normal curvature direction; 4. the reverse sphere in bight: long limit or side edge shape for the bight change rapid glass, and the bight is easy to generate reverse sphere; 5. optical property is not good: because the influence of factors such as glass sheet shape, mould anchorage force, glass sheet temperatures difference, the glass spherical transition that the center sphere is bigger has some setbacks, and optical property is not good.
