As shown in fig. 1 and 2, the working chamber 3 is sequentially divided into a preheating chamber, a heating chamber and a cooling chamber, the preheating chamber and the heating chamber are formed by dividing a partition plate 31 arranged on the inner wall of the working chamber 3, the distance between the partition plate 31 and the conveying chain plate 2 is greater than the thickness of the mold 4, and the heating device 5 is arranged in the heating chamber. The heat that baffle 31 produced heating device 5 is mostly stayed the heating intracavity and is heated the glass on mould 4, and the clearance between baffle 31 and transport link joint 2 supplies the partial heat outflow entering preheating intracavity in the heating intracavity for the temperature in preheating the intracavity can preheat the glass that lies in preheating the intracavity, makes the comparatively steady intensification stage of having of glass, reduces the production of stress.

As shown in fig. 1 and 2, the heating chamber and the cooling chamber are divided by a heat insulation plate 33, and the heat insulation plate 33 is vertically movably inserted into an insertion opening 32 which is formed in the top wall of the working chamber 3 and cuts off the working chamber 3.

The outer side wall of the cooling chamber is provided with a plurality of heat dissipation plates 34 to improve the cooling efficiency of the cooling chamber. The top wall of the working chamber 3 is provided with a first air cylinder 331, the telescopic end of the first air cylinder 331 is connected with the heat insulation plate 33, the heat insulation plate 33 is driven to move by the first air cylinder 331, and the automation degree of the glass hot bending machine tool is improved.

As shown in fig. 1, be provided with air-cooler 7 on the frame 1, the air-out end of air-cooler 7 aims at the outside transport link joint 2 setting of working chamber 3, and air-cooler 7 cools down to the transport link joint 2 that is located outside the cooling chamber to the phenomenon emergence that the higher damage that appears of transport link joint 2 temperature after preventing many times of transportation.

The working process is as follows:

the operator places the glass on the mold 4 and subsequently places the mold 4 on the conveyor chain 2. The operator starts the transport chain plate 2 and the second cylinder 61 to convey the first mold 4 into the heating cavity, and at this time, the second mold 4 is located in the preheating cavity, and at this time, the heating device 5 is started. The temperature in the heating cavity rises, and the temperature in the preheating cavity also rises at the moment, and the temperature in the heating cavity is always higher than the temperature in the preheating cavity under the action of the partition plate 31. After the deformation of the glass in the first mold 4 is completed, the conveying chain plate 2 works, the first air cylinder 331 works, the second air cylinder works, the first mold 4 is conveyed to the cooling cavity to be cooled after the heat insulation plate 33 rises, the second mold 4 is conveyed to the heating cavity to be heated, and the third mold 4 enters the preheating cavity. At the moment that heat insulating board 33 is opened, the hot gas flow in the heating chamber gets into the cooling chamber for the temperature in the cooling chamber rises slightly, seals the cooling chamber along with heat insulating board 33, and the temperature in the cooling chamber slowly descends under natural cooling, because of work cavity 3 is cut off to socket 32, and the temperature in the heating chamber can't be conducted to the cooling chamber in from the lateral wall of work cavity 3 through heat-conducting effect, so that the temperature in the cooling chamber can better reduction. The glass on the first mold 4 in the cooling chamber has a relatively smooth cooling phase, thus reducing the generation of stress. After the glass on the second mould 4 is bent, the first cylinder 331, the second cylinder 61 and the conveying chain plate 2 all work, the first mould 4 is transported away from the working chamber 3, the second mould 4 is transported towards the cooling cavity, the third mould 4 is transported towards the heating cavity, the fourth mould 4 is transported towards the preheating cavity, and then the operator takes down the first mould 4 and puts the fifth mould 4.
