116 and 117 two sides is all machined with frame trough, can slow down the ramp rates of mold and its interior blank or product after mounting,
Including temperature rise speed or temperature drop speed.
And the described second cooling mould group 320 preferably includes: countercylinder 211, the Your Majesty's coldplate from top to bottom set gradually
112, Your Majesty's heating plate 113, main lower heating plate 114 and main lower coldplate 115, the countercylinder 211 are vertically arranged, and Your Majesty is cooling
Plate 112, Your Majesty's heating plate 113, main lower heating plate 114 and main lower coldplate 115 are placed in molding room 400, and Your Majesty is cooling
Plate 112 is connected to the lower end of countercylinder 211, and Your Majesty's heating plate 113 is connected under Your Majesty's coldplate 112, Your Majesty's heating plate 113
Bottom surface for being in contact with the top surface of mold, the top surface of main lower heating plate 114 for being in contact with the bottom surface of mold, it is main lower plus
Hot plate 114 is connected on main lower coldplate 115.
Similarly with the described first cooling mould group 310, the Your Majesty's heating plate 113 and Your Majesty in the second cooling mould group 320 are cold
But be also provided between plate 112 and between main lower heating plate 114 and main lower coldplate 115 a two-sided flase floor 116 and
117, setting position of two-sided flase floor 116 and 117, function are identical with the first cooling mould group 310 at this.
Therefore, cooling device 300 provided by the present invention, due to using in pipeline system distribution and being connected on molding
The cooling mould group 310 of the first of room 400 and the second cooling mould group 320, so that the product after molding under the condition of high temperature, logical first
Cross while the first cooling mould group 310 is cooled down and carry out stablizing pressure maintaining, then by the second cooling mould group 320 carry out it is cooling,
To accelerate mold and shaped article placed within to move back warm speed, production efficiency is not only improved, but also effectively prevent product
Fragmentation；After effective solution hot-press equipment molding smart phone 3D bend glass, the natural type of cooling, production effect are used to it
The problem of rate is low, and use liquid cooling plate cooling mode be easy to cause product fragmentation.
In the present invention further preferred embodiment, the cooling device 300 further include: with 400 phase of molding room
It connects and arranges with the described first cooling mould group 310 and the second cooling mould group 320 in pipeline system, for the side by heat transfer
Formula carries out the cooling mould group 330 of third cooling three times to product after molding；Connect with the molding room 400 and with it is first cold
But the cooling mould group 320 of mould group 310, second and the cooling mould group 330 of third are arranged in pipeline system, for by way of heat transfer
Four the cooling the 4th cooling mould groups 340 are carried out to product after molding.
The third cooling device 300 and the 4th cooling device 300 all include: the countercylinder from top to bottom set gradually
211, upper liquid cooling plate and lower liquid cooling plate, the countercylinder 211 are vertically arranged, and upper liquid cooling plate and lower liquid cooling plate are placed in molding room
In 400, upper liquid cooling plate upper surface is used to connect the lower end of countercylinder 211, lower end surface is used to be in contact with mould upper surface, lower liquid
Cold plate upper surface with mold bottom surface for being in contact.
As can be seen that the cooling mould group 330 of the third and the 4th cooling mould group 340 are cooling mode, by two liquid cooling plates
It is bonded respectively with mold upper and lower end face, then by constantly circulating in the coolant liquid in liquid cooling plate, carries out heat with mold
Exchange, to carry out rapid cooling to product after mold and its interior molding.This cooling be in mold and product, to have passed through first cold
But mould group 310 stablize pressure maintaining and cooling and moved back again by the second cooling mould group 320 it is both warm to carrying out after certain temperature,
The production efficiency of product can only be further speeded up by carrying out chilling cooling at this time, without will cause product in the extremely short time by high temperature
It is reduced to low temperature, product fragmentation.High temperature and low temperature are that in contrast, the difference according to product after different blanks or molding is bent
Face, and difference is required, it is the common knowledge of this field, is no longer illustrated one by one herein.
As shown in fig. 6, in the present invention further in preferred embodiment, the cooling device 300 further include: with it is described at
Type room 400 is connected to, for carrying out the liquid cooling channel 360 of supplement heat rejecter to product after four cooling moldings of completion；And with institute
It states liquid cooling channel 360 to connect, for while product carries out supplement heat rejecter after the molding of 360 pairs of liquid cooling channel, carry out five to it
The cooling mould group 350 of the 5th of secondary cooling.
It is preferred that the liquid cooling channel 360 and the molding room 400 are perpendicular, and the 3D bend glass hot-press method also wraps
Feeding device is included, the feeding device and the molding room 400 are perpendicular, and set up separately with liquid cooling channel 360 in molding room 400
Both ends, space between the two are the operating space of operator.The operation order of entire 3D bend glass hot-press method are as follows: behaviour
Make personnel monolithic flat glass blank is placed in mold, then mold is placed on feeding device, feeding device induction
To mold (hereafter the mold is all the mold for being built-in with monolithic flat glass blank to this section), mold is delivered to molding automatically
Room 400, making it by preheating device 200(includes successively multiple successively carrying out being gradually warmed up preheating to mold in molding room 400
Pre- thermal module), molding press device (at least one similarly with preheating modular structure, function is the press-moulding die group of die mould), cooling dress
Exported after setting 300, last output mask be exactly liquid cooling channel 360(or can extend one section of channel without liquid cooling function,
Extending direction can be parallel with molding room 400).The operation of entire hot-press equipment is extremely convenient, puts from 400 one end of molding room
Enter, the other end takes out.
When it is implemented, the liquid cooling channel 360 includes: the channel body being connected to the molding room 400, and setting
In the liquid cooling pipeline in the channel body.And the 5th cooling mould group 350 can be used it is identical with the cooling mould group 330 of third
