Description
Technical field
This utility model is related to safety glass field, especially a kind of mould of double curved toughened glass, Yi Jipei
Have the production line of the double curved toughened glass of this mould.
Background technology
Mainly include on the production line of double curved toughened glass：Upper fragment, bringing-up section, profiled section, tempering section and unloading piece
Section, glass plate complete tempering molding through above-mentioned process section.In existing process, one of which technique is：Use in profiled section
Glass plate is curved by mold and lower mould according to the radian for setting, specifically：Formed in the lower surface of mold negative
Pressure, departs from rollgang, mold and lower mould matched moulds using negative-pressure adsorption glass plate, and after die sinking, the glass plate of brake forming falls
Enter and transport in mould, as transhipment mould enters the tempering section in downstream.
As safety glass needs to keep the condition of high temperature when tempering section is entered, therefore mend to glass plate in profiled section
The necessary means that heat is production high-quality safety glass are filled, some technical staff can add resistance wire in the inner chamber of mold
To heat up to glass plate, but this radiant heating is limited in scope, it is impossible to enough temperature are given in the demoulding and is supplemented, glass
Plate yet suffers from larger temperature loss in the demoulding；This resistance wire is also undesirable to heats at glass plate edge；Separately
Outward, close down vacuum generator during the current glass plate demoulding, using glass plate deadweight separate with mold, processing thinner thickness or
During the less glass plate of book size, it may appear that cannot detached situation.As can be seen here, in the production line of double curved toughened glass
Profiled section still have improve and lifted space, it would be highly desirable to solve.
Utility model content
For solving the above problems, one of the purpose of this utility model is to provide a kind of shaping mould of double curved toughened glass
Tool, can provide enough temperature and supplement, while also avoid glass plate cannot be detached with mold in the glass plate demoulding
Situation, improves the crudy of double curved toughened glass；The two of the purpose of this utility model are to provide one kind equipped with this
The production line of the double curved toughened glass of mould.
For achieving the above object, the technical solution of the utility model is as follows：
A kind of mould of double curved toughened glass, the mould include：Mold and lower mould, the mold
Interior vacuum chamber is connected with vacuum generator, and the lower surface of mold is distributed with several pores connected with the vacuum chamber；
The vacuum chamber is connected with the gas supply device for spraying fuel gas in the demoulding by the pore to glass plate.
Further, the gas supply device mainly includes：Gas storage tank, the gas storage tank and the vacuum chamber
Between be connected with gas supply pipeline, be provided with electromagnetic valve and check valve on the gas supply pipeline.
Further, natural gas or liquefied petroleum gas are stored in the gas storage tank.
Further, the vacuum generator is connected with the vacuum chamber by exhaust pipe.
Further, the vacuum intracavity is provided with electrical heating elements.
Further, the temperature of the glass plate is 600 DEG C to 700 DEG C.
A kind of production line of double curved toughened glass, the production line include fragment, bringing-up section, profiled section, tempering section
With unload fragment, be provided with above-mentioned mould on the profiled section.
Advantage of the present utility model has：
1st, the fuel gas of malleation is passed through to the vacuum chamber of mold, and the gas pressure increase of vacuum intracavity reaches glass
Plate purpose detached with mold, in solution prior art after shaping glass sheets, especially only relies on after thin glass plate molding certainly
Heavy sensation of the body power is not easy the problem come off from mold, has ensured the continuous, stable of production process.
2nd, after separating, between 600 DEG C -700 DEG C, fuel gas starts after high temp glass plate is run into the temperature of glass plate
Burning, so that compensate heating in the glass plate demoulding to glass plate；As fuel gas is by being distributed under mold
The pore on surface sprays to glass plate, and fuel gas is more abundant with air contact in glass sheet perimeter, therefore to glass sheet perimeter
Part enables in particular to carry out sufficiently compensation heating；Heat radiation in matched moulds using electrical heating elements compensates heating,
Using fuel gas compensation heating during the demoulding, two kinds of heating mode combinations make glass plate protect in whole forming process
The condition of high temperature is held, so as to improve tempering quality.

Specific embodiment
Below in conjunction with the accompanying drawings specific embodiment of the present utility model is illustrated.
A kind of mould of the double curved toughened glass shown in Fig. 1, the mould include：Mold 1 and lower mould
2, there is a vacuum chamber 3 inside mold 1, several pores 4, pore 4 and vacuum chamber on the lower surface of mold 1, is distributed with
3 connections, vacuum chamber 3 are internally provided with electrical heating elements 11, and in this example, electrical heating elements 11 are resistance wire.Vacuum occurs
Device 5 is connected with the vacuum chamber 3 of mold 1 by exhaust pipe 6.Vacuum chamber 3 is also associated with gas supply device, in this example
In, gas supply device is specifically included：Gas storage tank 7, is connected with gas supply pipe between gas storage tank 7 and vacuum chamber 3
Road 8, is provided with electromagnetic valve 9 and check valve 10 on gas supply pipeline 8, and electromagnetic valve 9 is used for controlling the logical of gas supply pipeline 8
Disconnected, check valve 10 prevents gas backstreaming.The combustible gas of the cleanings such as natural gas or liquefied petroleum gas is stored in gas storage tank 7
Body.After fuel gas is sprayed from pore 4 or touch and burn, so as to heating is compensated to glass plate.
During use, mold 1 is descending under the drive of elevating mechanism, 9 closure state of electromagnetic valve, starts vacuum generator 5,
Negative pressure is formed in the vacuum chamber 3 of mold 1 to adsorb the glass plate on rollgang 12 in its lower surface, mold 1 and lower mould
Having 2-in-1 mould deforms bending glass sheet, closes vacuum generator 5 after molding, and 9 open mode of electromagnetic valve, fuel gas enter true
Cavity 3, as the gas pressure in vacuum chamber 3 increases, glass plate comes off, while fuel gas touch temperature for 600 DEG C-
Start to burn after 700 DEG C of glass plate, so as to compensate glass plate heating.
