Two descend heating plates 72 and for driving the second drive member 73 that heating plate 71 is gone up and down on second, heating plate 71 and second on second
Lower heating plate 72 respectively heats cope plate 21 and lower template 22.
The first drive member 514, the second drive member 73 and third drive member 33 in the present embodiment are both preferably gas
Cylinder, the lower heating plate 72 of heating plate 71, second in the lower heating plate 512, second of heating plate 511, first, heating plate in third on first
31 and third under heating plate 32 be all to be made using wolfram steel plate.
The specific embodiment of the production method of hot bending mobile phone glass cover board in the present invention are as follows: be placed with glass pieces 1
Mold 2 is sent into the molding room 4 of sealing by delivery device, is full of nitrogen in molding room 4 at this time, and mold 2 is by delivery device from the
31 lower section of heating plate is successively pushed to heating plate 31 in the third of the 7th pre- thermal module 3 in the third of one pre- thermal module 3
Lower section, the glass pieces 1 in mold 2, will under self gravitation effect due to the Effect of Hyperthermic Environment by seven pre- thermal modules 3
It can be in collapsed position, to complete preheating molding to glass pieces 1；Delivery device, which again pushes to mold 2 under first hot pressing, to be inhaled
The lower section of heating plate 511 on the first of mould group 51, inhaled under the first hot pressing the first drive member 514 of mould group 51 by drive thereon the
Heating plate 511 pushes cope plate 21 on one, while the vacuum cups 513 in the first lower heating plate 512 thereon vacuumizes, with right
The hot pressing and lower suction of the progress first stage of glass pieces 1；The completion of mould group 51 is inhaled under first hot pressing to the first stage of glass pieces 1
After hot pressing and lower suction, heating plate 511 in the first drive member 514 driving first of mould group 51 is inhaled under the first hot pressing and is risen, push
Mechanism urges mold 2 is moved under the second hot pressing 511 lower section of heating plate on inhale mould group 52 first, and mould group 52 is inhaled under the second hot pressing
The first drive member 514 by drive thereon first on heating plate 511 push cope plate 21, make cope plate 21 and lower template 22
Between reserve the surplus of 0.1 ± 0.01mm, while the vacuum cups 513 in the first lower heating plate 512 thereon vacuumizes, with right
The hot pressing and lower suction of the progress second stage of glass pieces 1；The completion of mould group 52 is inhaled under second hot pressing to the second stage of glass pieces 1
Hot pressing and lower suction after, under the second hot pressing inhale mould group 52 the first drive member 514 driving first on heating plate 511 rise, push away
Mechanism urges mold 2 is sent to be moved to 511 lower section of heating plate, lower the first drive member for inhaling mould group 53 on the first of lower suction mould group 53
514 by driving thereon first on heating plate 511 be connected to cope plate 21, between cope plate 21 and lower template 22 reserve 0.1 ±
The surplus of 0.01mm, the lower vacuum cups 513 inhaled in mould group 53 in first lower heating plate 512 vacuumize, with to glass pieces 1 into
The lower suction of row phase III, under suck into.Heating plate 511 rises in lower the first drive member 514 driving first for inhaling mould group 53,
Delivery device pushes mold 2 to be moved on first the lower section of heating plate 511 on inhale mould group 54 first, and the of mould group 54 is inhaled on first
One drive member 514 by drive thereon first on heating plate 511 push cope plate 21, between cope plate 21 and lower template 22 still
The surplus of 0.1 ± 0.01mm is reserved, the cope plate 21 inhaled in mould group 54 on first starts to vacuumize, to carry out to glass pieces 1
The upper suction of first stage, inhale on second mould group 55 with mould group 56 is inhaled in third all as suction mould group 54 on first, with right respectively
