A kind of forming mould of 3D bend glass

Technical field

The utility model relates to a kind of forming mould of 3D bend glass, belongs to touch panel and manufactures field.

Background technology

At present, people adopt cold processing technique manufacture for the 3D bend glass of touch-screen usually, and wherein, 3D is the abbreviation of English " 3Dimensions ", and 3D is the concept in space, that is, the space be made up of X, Y, Z tri-axles.The typical process flow of this cold processing technique is: sheet glass → profile removes abrasive lapping → rough grinding → smooth grinding → surface finish → external diameter processing sizing → chemical enhanced → 3D bend glass.This traditional cold processing technology exists that manufacturing time is long, to manufacture efficiency low and to the complex-curved problem that cannot manufacture.Therefore, how to research and develop a kind of new technology manufacturing 3D bend glass, effectively can solve the cold processing technique Problems existing that tradition manufactures 3D bend glass, be people's problem demanding prompt solution always.

Utility model content

The utility model provides a kind of forming mould of 3D bend glass, this forming mould is sent in molding device and carries out hot-forming process, efficiently solve traditional cold processing technique in manufacture 3D bend glass process, the manufacturing time of existence is long, to manufacture efficiency low and to the complex-curved problem that cannot manufacture.

The utility model provides a kind of forming mould of 3D bend glass, and described forming mould is made up of master mold and male model; Wherein,

Described master mold is by master mold main body and all have the top formed body of bending side and bottom formed body forms, and described master mold main body is arranged between described top formed body and described bottom formed body;

Described male model is identical with the shape of described master mold main body, and it is dimensioned slightly smaller than the size of described master mold main body.

Further, the bending angle of described bending side is 90-135 degree.

The utility model manufactures 3D bend glass by adopting forming mould, efficiently solves traditional cold processing technology in manufacture 3D bend glass process, and the manufacturing time of existence is long, it is low and to the complex-curved problem that cannot manufacture to manufacture efficiency.

Embodiment

For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

Embodiment 1

As shown in Figure 1, present embodiments provide for a kind of forming mould of 3D bend glass, this forming mould is made up of master mold and male model 5; Wherein,

Master mold is by master mold main body 1 and all have the top formed body 2 of bending side 4 and bottom formed body 3 forms, and master mold main body 1 is arranged between top formed body 2 and bottom formed body 3;

Male model 5 is identical with the shape of master mold main body 1, and it is dimensioned slightly smaller than the size of master mold main body 1.

Wherein, the bending angle of bending side 4 is 90-135 degree.

Embodiment 2

The utility model can select the sheet glass of following table numbering 1-5 as the starting material manufacturing 3D bend glass.

The manufacture method of the utility model 3D bend glass, make use of the forming mould of the 3D bend glass of embodiment 1, and its concrete manufacturing processed is as follows:

As shown in Figure 2, be first arranged at by sheet glass 6 on the left surface of male model 5, its mode arranging flat glass 6 has multiple, such as: can be adsorbed on male model 5 left surface by the mode of absorption.In addition, the size of sheet glass 6 is greater than the size of the left surface of male model 5, and the selection of its sheet glass 6 size is selected according to the requirement of product 3D bend glass.

As shown in Figure 3, the male model 5 being adsorbed with sheet glass 6 is moved to master mold main body 1, master mold main body 1 one side that its sheet glass face 6 is docked with bending side 4 fits tightly, now will be positioned at the upper and lower top formed body 2 of master mold main body 1 and bottom formed body 3 moves relative to the master mold main body 1 fitted tightly and male model 5, thus the edge of the sheet glass 6 of absorption on male model 5 is bent.Re-use cylinder this forming mould is sent in molding device, and temperature 800-900 DEG C, carry out hot-forming process 1-2min under pressure 10-20MPa, obtain 3D bend glass, wherein, the bending angle of described bending side is 90-135 degree.

Under the driving of cylinder, the forming mould of 3D bend glass is released from molding device, carry out being cooled to room temperature, from this forming mould, take out the 3D bend glass made.

Shaping 3D bend glass is placed in concentration be 99% potassium nitrate solution soak 4-6h, the 3D bend glass after chemical intensification treatment takes out from potassium nitrate solution, dries.

The manufacture method of the utility model 3D bend glass, only adopt this forming mould and sent in molding device and carry out hot-forming process and chemical intensification treatment, compared with traditional cold processing technique, eliminate profile and remove the treatment steps such as abrasive lapping, rough grinding, smooth grinding and surface finish, obviously shorten the manufacturing time of 3D bend glass, thus effectively raise manufacture efficiency.

Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
