Specific embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing.It should be understood that herein Described specific embodiment is only used for describing and explaining the present invention, and is not intended to limit the utility model.
In the present invention, in the absence of explanation to the contrary, the noun of locality used such as " upper and lower, left and right " is usual Refer to reference to upper and lower, left and right shown in the drawings；" inside and outside " refers to the inside and outside of the profile relative to each component itself.
Referring to shown in Fig. 3 to Fig. 6, according to a kind of bend glass hot bending mold of preferred embodiment of the utility model, Including upper mold 1 and lower die 2.The lower die 2 is formed with type chamber 21, and upper mold 1 is formed with the forming face 11 to match with the type chamber 21.Root According to mould applications common sense it is found that when upper mold 1 snap into lower die 2 forming face 11 is matched with type chamber 21 when, the two Between limit the space of accommodating glass material, and make glass be shaped to predetermined shape using the shape in the space.Preferably, In the state that upper mold 1 is bonded to lower die 2, with the gap of 0.5mm~1.5mm between forming face 11 and the cavity wall of type chamber 21.
In the present invention, as shown in Figure 3 and Figure 4, the upside of upper mold 1 is formed with cavity 12, the cavity 12 be located at The surface in shape face 11.By the way that the cavity 12 is arranged, it is possible to reduce the use of base mould material.Due to subtracting for mold solid volume It is small, mold can be made to reach required temperature with relatively small number of heat when heated, and while cooling with less cooling Water is reduced to required cooling temperature, it is thus possible to the heat in glass preparation and cooling water inflow demand be effectively reduced, to mention It rises manufacture efficiency and reduces production cost.
Above-mentioned cavity 12 is formed in the surface of forming face 11, convenient for passing through the position for being appropriately arranged with heating tube or cooling tube 3 It sets and makes the glass wherein carried quickly and evenly heated or cooling, and ensure that upper mold 1 keeps relatively high overall stiffness, Meets the needs of applying appropriate pressure.Meanwhile the utility model can only form one block of bend glass in a mold, it can Temperature and pressure needed for easily control preparation guarantees product product while improving manufacture efficiency, reducing production cost Matter.
The cavity 12 of upper mold 1 can be formed as a variety of suitable shapes, such as can be according to the vertical throwing of molding glass Shadow shape is correspondingly arranged.Normally, cavity 12 is the cylinder cavity with flat bottom surface, thus has bottom surface and around the bottom The side wall surface in face.Concentrate, improve the intensity of mold in order to reduce stress, it is the joint of the bottom surface of cavity 12 and side wall surface, adjacent The joint of side wall surface can be formed as arc transiting surface.
Further, the fitting periphery 121 that upper mold 1 and lower die 2 can be respectively formed with horizontal extension and be bonded each other, and The upside of the fitting periphery 121 of upper mold 1 could be formed with the groove 13 around cavity 12, it is possible thereby to reduce upper mold 1 Dilatancy amount, and reduce raw material usage.Since the fitting periphery 121 is mainly used for closing between forming face 11 and type chamber 21 Molding space, thus its intensity can't be significantly reduced because groove 13 are arranged.
The mold of the utility model can be using typical lower die (as shown in Figure 2) in the prior art.In a kind of preferred reality It applies in mode, the downside of lower die 2 could be formed with the stage portion 22 of circulating type chamber 21.And/or the downside of lower die 2 can be with Form bottom groove 23, the depth of the bottom groove 23 be less than the depth of the cavity 12 in upper mold 1 and be located at type chamber 21 just under Side.By the way that these stage portions 22, bottom groove 23 are arranged, raw material usage can be further decreased, and improve heat conduction efficiency And cooling efficiency, thus improve glass production efficiency.
As shown in Figure 4 and Figure 6, cavity 12 and bottom groove 23 are respectively corresponded forming face 11 and type chamber 21 by the utility model Setting, and stage portion 22 can be set with circulating type chamber 21, it is possible thereby to make heating tube or cooling tube 3 symmetrical in glass manufacture It is arranged in the hot bending position corresponding to bend glass.To, during heating, the hot bending position of bend glass can quickly by Heat heating reaches softening temperature, and middle plane part heating rate is then relatively slow, this part will not be excessively high in glass because of temperature Glass surface generates point, it is ensured that the surface quality of glass planar part.Similarly, while cooling, can to heat up higher Design temperature is quickly down in part, convenient for improving production efficiency.
Mold should thermal stability with higher, against influence of thermal deformation glass forming quality.For this purpose, this is practical new The upper mold 1 and lower die 2 of type can be made of graphite, non-metal stupalith or Ti (C, N) base metal-ceramic material.
Normally, bend glass may be used as display panel.In order to preferable aesthetic effect, edge or corner (circle) arc can be formed as by dividing.For this purpose, the base angle of type chamber 21 can be made to be formed as arc, vertical projection can be fillet It is rectangular etc..
It is understood that being added with above-mentioned bend glass hot bending with what mold was used cooperatively with the progress of processing step Heat pipe or cooling tube 3 and its temperature can be different.For example, heating tube is bonded as shown in thermoformed areas Mould 1 and lower die 2 bring it about hot bending deformation to heat glass therein；Cooling (annealing) is carried out into next station later, The pipe substitution at this point, heating tube is cooled, so that glass is cooled to predetermined temperature by predetermined speed.Wherein, it is imitated to improve heat transfer Rate, in a kind of glass heat bender of preferred embodiment, the heating tube or cooling tube 3 of use can have elliptic cross-section, Can there is biggish fitting area with the upper mold 1 (cavity 12) and lower die 2 of cooperation.
Preferred embodiments of the present invention, still, the utility model and unlimited are described in detail in conjunction with attached drawing above In this.In the range of the technology design of the utility model, a variety of simple variants can be carried out to the technical solution of the utility model, It is combined in any suitable manner including each particular technique feature.In order to avoid unnecessary repetition, the utility model To various combinations of possible ways, no further explanation will be given.But these simple variants and combination equally should be considered as the utility model institute Disclosure belongs to the protection scope of the utility model.
