The invention has the beneficial effects that:

the traditional glass forming mode is improved, the cooling part and the ejection part are used in combination with the glass forming process, the cooling device 5 is preliminarily driven to cool the upper layer of the glass to be formed by utilizing the pressing process of the upper die 2 in the forming process, the trigger tube 66 can be in contact with the cold guide device 6 in the lower die 1 and is communicated with the cold guide device 6 to conduct cooling gas with the interior of the lower die 1 in the subsequent pressing process, so that the lower layer of the glass to be formed is cooled, the good cooling forming effect of the glass to be formed is achieved, the forming efficiency is improved, meanwhile, the lower die 1 and the upper die 2 are still in a laminating forming state, the conditions of uneven surface and uneven thickness in the glass forming process are avoided, and the qualified rate of glass forming is improved.

When the upper die 2 is pressed down and combined with the lower die 1 to mold a molten glass block and the upper die 2 moves out, the abutting rod 43 is driven to contact with the ejector plate 42 in the lower die 1, so that the ejector plate 42 respectively realizes two states of the ejector plate 42 exiting from the die cavity of the lower die 1 and entering into the die cavity of the lower die 1 along with the downward movement and the upward movement of the abutting rod 43, wherein when the ejector plate 42 exits from the die cavity of the lower die 1, the closing part 44 moves upwards to close the communication part, thereby keeping the die cavity shape of the lower die 1 without influencing the glass molding process, and after the glass is molded, the ejector plate 42 enters into the die cavity of the lower die 1 to eject the molded glass, because the molded glass has certain hardness after being cooled by the cooling device 5 and the cold conducting device 6, the ejector plate 42 can not damage the glass when being contacted with the molded glass, thereby realizing better ejection effect on the glass during cooling molding, and this ejecting device 4 need not to set up the power supply and drives, and the shaping action with last mould 2 and lower mould 1 cooperatees, can realize ejecting effect in the shaping process.

The working principle is as follows: the lower die 1 filled with the molten glass block moves to the upper die 2, firstly, the upper die 2 and the guide post 3 move downwards, the guide post 3 is contacted with the lower die 1, the position-resisting rod 43 is inserted into the lower die 1 to push the transverse ejection plate 421 to move into the transverse ejection groove 411 and drive the vertical ejection plate 422 to move into the vertical ejection groove 412, the closing block 441 moves upwards to close the transverse ejection groove 411 to complete the storage step of the ejection mechanism, then, the lower pressure head of the upper die 2 continuously moves downwards to enter the die cavity of the lower die 1 to form the molten glass block, meanwhile, the trigger tube 66 is inserted into the air guide cavity 61 in the lower die 1 and is contacted with the trigger plate 6a to drive the trigger plate 6a to move, after the lower pressure head completes the forming step of the molten glass block, the trigger plate 6a drives the closing plate 651 to move into the air guide groove 6, the air guide tube 64 is communicated with cold air circulating in the trigger tube 66 to perform accelerated cooling forming on the glass to be, namely, the glass forming operation is completed, the upper die 2 is moved out of the lower die 1, the trigger plate 6a and the horizontal ejector plate 421 are sequentially separated from the contact between the trigger tube 66 and the abutting rod 43, the closing plate 651 and the closing block 441 are reset, and at the moment, the horizontal ejector plate 421 and the vertical ejector plate 422 eject the formed glass, namely, the cooling forming and ejecting process of the whole glass forming process is completed.

The embodiments of the present invention are disclosed as the preferred embodiments, but not limited thereto, and those skilled in the art can easily understand the spirit of the present invention and make various extensions and changes without departing from the spirit of the present invention.
