The utility model embodiment provides a kind of glass hot-bending die, for heat-bending glass part 100 (referring to Fig. 1 and Fig. 2),
Glass workpiece 100 includes treating the hot bending portion 110 of hot bending and does not need the non-thermal turn of bilge 120 of hot bending.In the present embodiment, as one
Plant and enumerate, the plate-like setting of effective object glass workpiece 100 of the glass hot-bending die, and two be oppositely arranged in hot bending portion 110
Side is provided with non-thermal turn of bilge 120.
As depicted in figs. 1 and 2, the glass hot-bending die includes position relationship upper bolster 200 and die shoe setting up and down
, located at the top of die shoe 300, die shoe 300 is located at the lower section of upper bolster 200 for 300, i.e. upper bolster 200.Upper bolster 200 is with
There is point mould state and a matched moulds state between die holder 300, and the die cavity for formed glass part 100 be formed with matched moulds state,
Wherein, upper bolster 200 and die shoe 300 refer to that upper bolster 200 and die shoe 300 are separated from each other in a point mould state, and upper bolster
Clearance distance between 200 and die shoe 300 is easy to be placed into glass workpiece 100 between the two and by glass workpiece 100 from both
Between take out, and upper bolster 200 and die shoe 300 refer to that upper bolster 200 and die shoe 300 cooperate one in matched moulds state
Play and be formed with the die cavity for formed glass part 100.
In the present embodiment, upper bolster 200 is included for heating hot bending portion 110 and being abutted with hot bending portion 110 before matched moulds
And after hot bending portion 110 reaches preset temperature gradually matched moulds to die shoe 300 hot bending mold insert 210, it is and non-thermal for heating
Turn of bilge 120 and after preset temperature is reached with 300 points of moulds of die shoe before hot bending portion 110 reaches preset temperature and in hot bending portion 110
Gradually matched moulds to die shoe 300 non-hot bending mold insert 220, position and the non-thermal turn of bilge 120 of non-hot bending mold insert 220 be correspondingly arranged,
The position of hot bending mold insert 210 is correspondingly arranged with hot bending portion 110, and hot bending mold insert 210 is that the hot bending being made up of conductive graphite sheet material is inlayed
Part 210.Based on this structure, in hot bending operation process, hot bending mold insert 210 is abutted with hot bending portion 110 before matched moulds and heats heat
Turn of bilge 110, and after hot bending portion 110 reaches preset temperature, hot bending portion 110 softens, then hot bending mold insert 210 and non-hot bending mold insert
220 gradually matched moulds to die shoe 300, and allow glass workpiece 100 to be engaged with die cavity, wherein, it is non-in whole hot bending operation process
Hot bending mold insert 220 be after hot bending portion 110 reaches preset temperature, just gradually matched moulds to die shoe 300, so, non-hot bending mold insert
220 are less than the time of contact of hot bending mold insert 210 and hot bending portion 110 with the time of contact of non-thermal turn of bilge 120, namely are the reduction of non-
Hot bending mold insert 220 and the time of contact of glass workpiece 100, the temperature of non-thermal turn of bilge 120 is reduced, postpones the softening of non-thermal turn of bilge 120,
So that non-thermal turn of bilge 120 is maintained at hardness higher, it is to avoid impurity produces pit at non-thermal turn of bilge 120, namely is the reduction of
The pit of glass workpiece 100, improves yield, and then reduces the follow-up polishing operation amount to glass workpiece 100, time-consuming, and subtracts
The workload of few staff.
Additionally, herein it should be strongly noted that glass hot-bending die also needs to be combined with for driving in use
The heater of upper bolster 200 and die shoe 300, and the drive device for driving upper bolster 200 to be moved to die shoe 300
Deng certainly, the drive device needs to meet the sequence of motion of hot bending mold insert 210 and non-hot bending mold insert 220, does not launch thin herein
State.
In the present embodiment, because conductive graphite piece has high heat conduction characteristic, to improve upper bolster 200 and die shoe 300
To the efficiency of heating surface of glass workpiece 100 under matched moulds state, die shoe 300 and non-hot bending mold insert 220 are made by conductive graphite sheet material.
As depicted in figs. 1 and 2, upper bolster 200 also includes non-hot bending mold insert is connected and be arranged at non-hot bending mold insert 220
First embedding glass part 400 of 220 lower ends, non-hot bending mold insert 220 is the non-hot bending mold insert 220 being made up of conductive graphite sheet material,
Hot melting temperature of the hot melting temperature of the first embedding glass part 400 higher than glass workpiece 100.Based on this, by the first embedding glass part
400 keep apart non-hot bending mold insert 220 and non-thermal turn of bilge 120, it is to avoid the graphite on non-hot bending mold insert 220 directly departs from glass
Glass part 100, so as to further reduce the pit of non-thermal turn of bilge 120, that is to say the pit for further reducing glass workpiece 100, improve
Yield, and then the follow-up polishing operation amount to glass workpiece 100 is reduced, it is time-consuming, and the workload for reducing staff.
Further, non-hot bending mold insert 220 offers the first fixing groove for housing the first embedding glass part 400, the
The size of one fixing groove is adapted with the first embedding glass part 400.Based on this structure, by the first embedding glass part 400
After being placed in the first fixing groove, restriction effect is played in the displacement of the cell wall of the first fixing groove to the first embedding glass part 400, you can kept away
Exempt from the first embedding glass part 400 be subjected to displacement on direction perpendicular to be opened up for the first fixing groove notch, the first glass can be avoided
When inserts 400 is collided with, the problem of displacement is easily produced.
As depicted in figs. 1 and 2, glass hot-bending die also includes the upper end of die shoe 300 is connected and be arranged at die shoe 300
And the second embedding glass part 500 relative with the position of non-thermal turn of bilge 120, die shoe 300 is to be made up down of conductive graphite sheet material
Die holder 300, the hot melting temperature of the hot melting temperature higher than glass workpiece 100 of the second embedding glass part 500.Based on this, by the second glass
The setting of glass inserts 500, reduces the contact with glass workpiece 100 of die shoe 300, so as to reduce the pit of glass workpiece 100, improves
Yield, and then the follow-up polishing operation amount to glass workpiece 100 is reduced, it is time-consuming, and the workload for reducing staff.
Further, non-hot bending mold insert 220 offers the second fixing groove for housing the second embedding glass part 500, the
The size of two fixing grooves is adapted with the second embedding glass part 500.Based on this structure, by the second embedding glass part 500
After being placed in the second fixing groove, restriction effect is played in the displacement of the cell wall of the second fixing groove to the second embedding glass part 500, you can kept away
Exempt from the second embedding glass part 500 be subjected to displacement on direction perpendicular to be opened up for the second fixing groove notch, the second glass can be avoided
When inserts 500 is collided with, the problem of displacement is easily produced.
In this embodiment, glass hot-bending die also includes the positioning for softening prelocalization glass workpiece 100 in glass workpiece 100
Structural member (not shown), so, before the softening of glass workpiece 100, to that is to say and abut glass workpiece 100 simultaneously in hot bending mold insert 210
Before softening glass workpiece 100, by locating formation, glass workpiece 100 can be positioned, it is ensured that hot bending mold insert 210 abuts to heat
Turn of bilge 110.
