Any one above-mentioned glass molding press device is used to carry out die mould to produce the method for glassware 39, including it is following
Step：
Step 1, installs glass molding press device, makes the discharge outlet of discharge nozzle 36 in the top of splicing station 47, and
Shear is set between discharge nozzle 36 and splicing station 47；
Step 2, starts rotating blade drive 7, and the driving rotation deep bid 10 of rotating blade drive 7 rotates, and makes module under one group
Part 2 stops after turning at splicing station 47；Then, glass metal 37 is expelled to from discharge nozzle 36 in lower mold assemblies 2 becomes glass
Glass material 38, is cut frit 38 by shear after the frit 38 of discharge reaches setting weight；
Step 3, starts rotating blade drive 7, and the driving rotation deep bid 10 of rotating blade drive 7 rotates, makes to be connected to frit
38 lower mold assemblies 2 stop after turning at die mould station 48；Then, mould main body 20 is downward in being driven by middle mould driving device 15
It is mobile, until the lower surface of middle mould main body 20 after the upper surface of lower die main body 11 with stopping；In middle mould main body 20 to moving down
In dynamic process, upper mold driving device 21 drives upper mould body 24 to move down, and the bottom surface of upper mould body 24 passes through middle mould main body
20 and continue the frit 38 being pressed down against in lower mold assemblies 2, make frit 38 along the internal face flowing of lower mode cavity and with middle mould
Main body 20, which coordinates, is shaped to glassware 39, and then upper mould body 24 is restricted stopping and pushes；Upper mould body 24 starts after stopping
Pressurize, resets middle membrane module 3 and upper die component 4 after pressurize；In the step, upper mould body 24, which reaches, pushes extreme position
Stop, upper mould body 24 can be carried out spacing by middle mould main body 20, and more preferably limit method is by extrusion process
The reaction force size that upper mould body 24 is given after the middle filling of frit 38 die cavity is spacing to carry out；Middle membrane module 3 and upper module
The mode that part 4 resets can be that upper mold driving device 21 drives upper mould body 24 to rise back to initial position, afterwards middle mould driving
Mould main body 20 rises back to initial position during device 15 drives；Preferable mode is that upper mold driving device 21 drives upper mould body
24 rise, and mould main body 20 rises during subsequent middle mould driving device 15 also drives, and upper mould body 24 is at the same time or first with middle mould main body 20
After reset；Step 4, starts rotating blade drive 7, and the driving rotation deep bid 10 of rotating blade drive 7 is rotated, made after pressurize is housed
Glassware 39 lower mold assemblies 2 turn at cooling station 49 after stop, glassware 39 is carried out by cooling station 49
Cooling；Influenced in view of glass cooling velocity by the coefficient of expansion, therefore cooling rate should not be too fast in this step, prevents glass
Product 39 is burst；
Step 5, starts rotating blade drive 7, and the driving rotation deep bid 10 of rotating blade drive 7 is rotated, made equipped with after cooling
Glassware 39 lower mold assemblies 2 turn at out station 50 after stop, glassware 39 is taken out.
Preferably, in step 2, before splicing by lower die main body heater 40 by lower die main body 11 be preheating to 400 DEG C with
On, cooling rate is too fast when can prevent that frit 38 from entering on 11 inner surface of lower die main body by preheating lower die main body 11,
The die mould defects such as cracked in die mould, cold line；By the mold pushing mechanism of high-order splicing component 6 by lower mold assemblies after the completion of preheating
2 jackings make the discharge port bottom surface of discharge nozzle 36 and the bottom surface of lower mode cavity keep specific range to the lower section of discharge nozzle 36, this is specific
The height of distance is 0.5~2.5 times of 36 internal diameter of discharge nozzle；Then, any one following splicing mode is selected to carry out splicing：
Splicing mode one, frit 38 after cutting is completely into after in the lower mode cavity of lower die main body 11, high-order splicing
The mold pushing mechanism of component 6 is just begun to decline, the initial position for making lower mold assemblies 2 return to before rising；
Splicing mode two, when frit 38 touches the surface of lower mode cavity, the mold pushing mechanism of high-order splicing component 6 is opened
Begin to decline until lower mold assemblies 2 return to the initial position before rising；During decline, the weight and shearing of discharging frit 38 fill
Put interior setting value it is equal when, shear cut frit 38；
The viscosity control of the frit 38 in lower mode cavity will be entered in 2000~8000poise, be preferably 3000~
6000poise；When carrying out different cultivars glass die mould, the temperature corresponding to identical viscosities is entirely different, according to viscosity and temperature
The functional relation and viscosity of degree are as glass stress, the main reflection physical quantity of mobility, therefore by viscosity during die mould
As the parameter controlled frit；Viscosity by carrying out frit 38, which controls, can effectively control clipping apparatus in glass
The cold line left on product 39；Carry out also needing to the recrystallization temperature section for considering glassware 39 during 38 temperature control of frit, should use up
Amount is avoided or quickly through recrystallization temperature section, prevents occurring devitrification problem in glass, influence the die mould quality of product；
In step 3, it is maintained at the temperature of upper mould body 24 by heating the heating of ring 26 during the pushing of upper die component 4
More than 450 DEG C；The dwell time of glassware 39 was controlled at 3.5~10 seconds；38 cooling temperature of frit in pressure maintaining period
Control can carry out temperature control according to frit weight, die mould required precision, to prevent product from moderate finite deformation occurs, control glass system
The temperature of product 39 makes its viscosity after pressurize reach 107.6More than poise；
In step 4, before being cooled down to glassware 39, internal fire polishing burner 43 is first passed through to glassware 39
Inside carries out flame polish, then carries out flame polish to the port part of glassware 39 by rim of a cup fire polishing burner 44；Throw
After the completion of light, glassware 39 is cooled to below glass strain temperature by glass cooling nozzles 45, by glass in temperature-fall period
The cooling rate of glass product 39 is controlled in 30~150 DEG C/s；
In step 5, the lower die mandril 13 of lower mold assemblies 2 is driven to move upwards by ejecting driving device 46, by lower die top
Bar 13 jacks up glassware 39 upwards disengages glassware 39 and the lower mode cavity of lower die main body 11, passes through manually or mechanically hand
Glassware 39 is taken out；After glassware 39 takes out, nozzle 42 is cleaned by lower die the lower mode cavity of lower die main body 11 is carried out
Cleaning.
Further preferably, in step 2, lower die main body 11 is preheating to 450 DEG C~500 DEG C, the height of the specific range is
0.75~1.25 times of 36 internal diameter of discharge nozzle, by the viscosity control of the frit 38 entered in lower mode cavity 3000~
4000poise；
In step 3, during pushing, the temperature of upper mould body 24 is set to be maintained at 550 DEG C~700 DEG C；By glassware 39
Dwell time control at 4.5~7 seconds, and make the corresponding viscosity of the temperature after pressurize of glassware 39 be 109poise
~1011poise；
