The integrated display of glass screen and foamed plastic
Technical field
The utility model relates to a kind of display, particularly relates to the integrated display of a kind of glass screen and foamed plastic, belongs to the injection molding technology field.
Background technology
Daily necessities at present a lot of markets is also just more traditional through all having used comparatively extensive, common shaped article after the injection mo(u)lding.Traditional shaped article all can because of the final designing requirement of product, cause single product through too much assembling the finished product shipment behind the processing procedure.Single-piece production, assemble production cost is strengthened, turn in processing procedure week the delivery cycle is prolonged.Glass screen formed product in the mould in the past all is the action of the glass screen edge being carried out gluing.Can be because the effect of glass screen edge gluing in the moulding production process, have influence on the associativity of forming plastic cement and glass screen, thereby make glass screen and plastic cement under the impact that is subject to external environment, the risk that can exist the glass screen edge to come unstuck and cause produce market to recall.
The utility model content
For the deficiencies in the prior art, the purpose of this utility model is, provides a kind of glass screen and foamed plastic integrated display, makes after the glass screen edge of display and the foamed plastic moulding more firmly bonding.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the integrated display of glass screen and foamed plastic, it is characterized in that: comprise glass screen, the edge of described glass screen is provided with pore, and described glass screen and foamed plastic are one-body molded.
The integrated display of aforesaid glass screen and foamed plastic is characterized in that: described foamed plastic is thermoplastic expanded resin.
The integrated display of aforesaid glass screen and foamed plastic is characterized in that: the diameter of described pore is 0.2~0.4 mm.
The beneficial effects of the utility model are: foamed plastic is melt into resinite with glass screen edge pore in mold cavity, make the foaming molten resin body in the mold cavity apply a pressure, thereby the surface pressure of foaming molten resin body is tightened on the glass screen edge, make bonding after glass screen edge and the foamed plastic moulding must be more firm; The utility model density is low, shockproof properties is strong, long service life, good heat-insulation effect, good seal performance, overall weight are light.

Fig. 2 is the structural representation that the utility model advances glue point and gum intaking passage.
The specific embodiment
For further disclosing the technical solution of the utility model, describe embodiment of the present utility model in detail below in conjunction with accompanying drawing: as shown in Figure 1, the integrated display of glass screen and foamed plastic, comprise glass screen 1, the edge of described glass screen 1 is provided with pore 2, and the diameter of described pore 2 is 0.2~0.4 mm.Described glass screen 1 is one-body molded with foamed plastic 3, and described foamed plastic 3 is thermoplastic expanded resin.
Processing method:
A. use external press device, utilize gas injection, through autocratic screw rod the foamed plastic of high-temperature digestion is foamed;
B. as shown in Figure 2, the glass screen 1 that the edge is provided with pore 2 and relevant electronic component installation is placed in the metal die die cavity 4 of having set, until foamed plastic behind corresponding pressure lower frothing, foamed plastic is put 5 places and injected in the mold cavities 4 along runner 6 advancing glue, in mold cavity 4, the pore 2 at foamed plastic and glass screen 1 edge is melt into resinite;
C. after cooling off in the mould, glass screen 1 is one-body molded with foamed plastic 3, directly makes product and main frame carry out the location combination that winding displacement docks and locks screw, makes the integrated display of glass screen and foamed plastic.
The mould die surface of using needs to adopt PVD coating, the pressed gas of annotating after the foam moulding can not sticked on the die surface, thereby make product surface produce foamed gas radiation stress.
Foamed plastic and glass screen edge pore are melt into resinite in mold cavity, make the foaming molten resin body in the mold cavity apply a pressure, thereby the surface pressure of foaming molten resin body is tightened on the glass screen edge, and the surface part of carrying out cooling post-foaming molten resin body in the mould is solidified.The display with glass screen of making lightweight that so just can be efficient, economic.
More than by description of listed embodiment, basic conception of the present utility model and basic principle have been set forth.But the utility model never is limited to above-mentioned listed embodiment, and every equivalent variations, improvement and deliberately of inferior quality behavior of change of doing based on the technical solution of the utility model all should belong to protection domain of the present utility model.
