Specific embodiment
The present invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1, the molding machine of the heavy caliber lanthanide optical glass of the present invention includes formation system and pre-heating system,
Wherein, formation system includes heating unit, molding machine and lifting gear 5, and heating unit is by 10 groups of shaping cover 1 and bottom duration and degree of heating
Into shaping cover 1 is used to ensure space temperature residing for molding machine；Molding machine is by 3 groups of molding die 2, bottom plate 8 and small handcart
Into pre-heating system is made of preheating cover 7 and preheating duration and degree of heating 6, and preheating duration and degree of heating 6 is arranged in preheating cover 7.
Shaping cover 1 hangs on furnace bottom, and discharge nozzle 9 is made to be arranged in shaping cover 1, is provided with heating element in shaping cover 1, has
There is heating function, temperature range is 500-100 DEG C；Molding die 2 is positioned on bottom plate 8, and molding die 2 can be circular mode
Tool, as Figure 2-3 or square dies, as illustrated in figures 4-5, bottom plate 8 is positioned on small handcart 3, and small handcart 3 is set
It can move horizontally on track 4 and along track 4.In order to facilitate the operation, bottom duration and degree of heating 10 and preheating duration and degree of heating 6 are separately positioned on
The different position of left and right two of track 4, to facilitate heating of the molding machine in the two regions.
Lifting gear 5 by hoistable platform 11 and elevator group into, elevator, which rotates, drives hoistable platform 11 to rise or fall,
Bottom duration and degree of heating 10 is arranged on hoistable platform 11, and below molding machine, bottom duration and degree of heating 10 can follow hoistable platform 11 1
Lifting.After hoistable platform 11 is gone up, track 4 will be exceeded and withstand small handcart 3 and move upwards, at this moment, molding machine
It is just arranged on hoistable platform 11 and follows 11 1 lifting of hoistable platform；And after hoistable platform 11 drops to certain position,
Small handcart 3 can be again fallen back on track 4 again.The lifting of molding machine is completed by the lifting of hoistable platform 11.
Since molding die 2 only has side without bottom surface, bottom plate 8 forms optical glass together with molding die 2
Mold, certainly, bottom plate 8 and molding die 2 can also be made of one structure.Embedded block 12 is provided on bottom plate 8,
