It includes mould and lower mould, goes up and is provided with the separator between mould and the lower mould, and the CFC piece of separator for keeping apart preforming piece usefulness is provided with the work piece reference column on the lower mould, go up be provided with on the mould with work piece reference column assorted locating hole structure, the preforming piece passes through the work piece reference column and sets up on the lower mould, goes up the mould, the lower mould both sides all are provided with the same bent angle structure. The utility model discloses shortcomings such as traditional curved surface processing technology degree of difficulty is big, the yield low, material loss is big can be overcome, the curved glass's of heat processing mode is used for reference, adoption and the similar technical route of the curved processing of glass heat, concurrent heating preforming piece and mould in the heating furnace, plastic deformation takes place for messenger's sapphire or ceramic material under the effect of mould power, and then forms the shape that the mould was prescribed a limit to.
Description
(1) technical field
The utility model relates to a kind of curved surface forming mould, is specifically related to a kind of sapphire and the shaping high temperature assembling die of ceramic material 2.5/3D.
(2) background technology
Along with the development of technology, in mobile phone industry, between different brands, the gap of performance and software systems can be more and more less, and people can a big chunk visual cognitive ability in cell phone appearance design (as Material selec-tion, color, shape etc.).In shape, because 2D plate glass screen process technology is simple and ripe, remain the main Types of existing mobile phone glass screen in the market.But the lifting required for mobile phone perception and sense of touch along with people, 2.5D glass screen, even 3D glass screen also progress into the visual field of manufacturer, and Motorola, Nokia, apple etc. all adopted 2.5D technique.In the near future, Ge great cell phone manufacturer likely adopts 2.5D, even 3D Mobile phone screen on the mobile phone of more polytypic.
In material, sapphire single-crystal has Good All-around Property, existing application on Mobile phone screen.Ceramic material good insulating, hardness is higher, than metal with plastics are more corrosion-resistant and can produce shades of colour, be very suitable for making phone housing, to meet the demand of people to cell phone appearance.But sapphire and ceramic material are hard brittle material at normal temperatures, Machining of Curved Surface is not only more difficult in technique, and yield rate is low, and spillage of material is also larger.Although, although sapphire and ceramic material are fragility, at a certain temperature also can deliquescing, demonstrate certain plasticity, and then can plastic bending be carried out.Therefore, the method machine-shaping similar with heat-bending glass can be adopted.
(3) summary of the invention
The purpose of this utility model is to provide one can overcome the shortcomings such as conventional curved-surface processing technology difficulty is large, yield rate is low, spillage of material is large, use for reference the processing mode of heat-bending glass, adopt and process similar technology path to glass bending, heating preforms and mould while of in heating furnace, make sapphire or ceramic material, under the effect of mold forces, plastic deformation occur, so formed mould limit sapphire and the ceramic material high temperature assembling die of shape.
The purpose of this utility model is achieved in that it comprises patrix 2 and counterdie 3, separator 6 is provided with between patrix 2 and counterdie 3, separator 6 is the CFC sheet of isolation preformed member 1, counterdie 3 is provided with Workpiece fixing post 4, patrix 2 is provided with the locating hole structure 5 matched with Workpiece fixing post 4, preformed member 1 is arranged on counterdie 3 by Workpiece fixing post 4, and patrix 2, counterdie 3 both sides are provided with identical corner structure.
The utility model also has some features like this:
1, described patrix 2, counterdie 3 and separator 6 surface are provided with one deck W or Mo layer;
2, described separator 6 comprises at least one CFC sheet, and CFC sheet both sides are provided with and form curved screens with patrix 2, corner structure that counterdie 3 is identical.
The utility model is in conjunction with the development trend of future market to curved screens wilderness demand.The beneficial effects of the utility model have:
1. make assembling die with W or Mo material and CFC, adopt hot bending process to make sapphire or ceramic flexure plane, can replace complicated Machining of Curved Surface process, technical process is simple, and production efficiency is high, and cost of manufacture is low.
2. adopt CVD by W or Mo layer high-purity on composite die surface deposition, can be that die surface is more level and smooth on the one hand, reduce surface roughness, improve the surface quality of profiled member; On the other hand, the immersion of C and storeroom under high temperature can be prevented, avoid the quality affecting profiled member.
(4) accompanying drawing explanation
Fig. 1 is the utility model structural representation.
(5) detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.Composition graphs 1, the present embodiment comprises patrix 2 and counterdie 3, separator 6 is provided with between patrix 2 and counterdie 3, separator 6 is the CFC sheet of isolation preformed member 1, counterdie 3 is provided with Workpiece fixing post 4, patrix 2 is provided with the locating hole structure 5 matched with Workpiece fixing post 4, preformed member 1 is arranged on counterdie 3 by Workpiece fixing post 4, and patrix 2, counterdie 3 both sides are provided with identical corner structure.
Preformed member 1 is sapphire or ceramic pre-shaped, upper and lower mould all adopts W or Mo material to make, and patrix 2, counterdie 3 both sides are provided with identical corner structure, and bent angle represents with R, 4 is the Workpiece fixing post on counterdie, and 5 is the locating hole structure matched with counterdie locating dowel.6 for isolating the CFC sheet of preformed member 1.Upper and lower mould and CFC sheet deposit high-purity W or Mo of one deck from the teeth outwards by CVD all in advance, and several CFC sheets (shown in figure a ~ e) can be adopted between upper and lower mould to isolate preformed member 1, can the multiple curved screens of one-shot forming.
The present embodiment detailed process is: put between patrix 2 and counterdie 3 piecewise by sapphire to be bent or ceramic pre-shaped 1, between preformed member, 1 separates with CFC sheet, mould is placed in the middle of resistance or high frequency, microwave electromagnetic heating furnace, under vacuum, noble gas or hydrogen shield atmosphere, preformed member is heated to the temperature that plastic deformation can occur, utilize mould self gravitation or external auxiliary pressure control device to make preformed member produce flexural deformation, become the shape that mould limits; After curved surface forming, in-situ annealing, slow cooling, eliminates thermal stress.
The utility model set forth a kind of sapphire and the shaping high temperature assembling die of ceramic material 2.5/3D, on idea basis of the present utility model, all can by similar means to obtain sapphire or ceramic flexure plane all belongs to protection domain of the present utility model.
