Description
Technical field
The present invention relates to glass moulding by casting fields.
Background technique
It in the production process of glassware, needs to form glass, need to be formed again using glass in glass forming step
Mold, glass-forming die are usually metal die, make its molding using metal die pressed glass product.Metal die surface
Operating temperature be generally 600-900 DEG C, and the temperature of melten glass liquid is 1300-1600 DEG C, under the conditions of such temperature,
Melten glass liquid easily adheres to metal die surface.
After glass molding, glass need to be demoulded, the prior art, which generallys use, directly takes out mold to glass progress
Demoulding, but often have the following problems: 1, in demoulding, glass is close to very much in mold, and glass is big by the pressure of mold,
Lead to not easy mold release；2, after demoulding, there is a water wave on formed glass surface and coarse since the friction of mold will cause surface, to make
It is rough to obtain glass surface, influences glass finished-product quality.
Summary of the invention
The invention is intended to provide a kind of easy mold release, and the processing for the glassware for making formed glass surface smooth after demoulding
Method.
The processing method of one of this programme glassware, including ingredient are melted, and form, annealing, walk in the molding
In rapid, using a kind of glass-forming die, including bed die, bed die is equipped with the internal pattern for forming cavity, and pattern is graphene
Material is made, and pattern pattern is surrounded by the first graphene board, the second graphene board, third graphene board and the 4th graphene board
Type chamber, the second graphene board and third graphene board are located at the two sides of the first graphene board, and the 4th graphene board is located at the
The upper end of two graphene boards and third graphene board, the top of the 4th graphene board are equipped with upper mold, and the side of pattern is equipped with first
Cavity, the other side of pattern are equipped with the second cavity, and exhaust outlet is offered on the first cavity, and the second cavity is equipped with air inlet, into
Port connects tracheae, and tracheae is equipped with blower and aspiration pump, and the middle part of bed die and upper mold is equipped with water cooling through-hole in the horizontal direction；
In the forming step, comprising:
(1) before being poured melten glass liquid, first into bed die and the water cooling through-hole of upper mold respectively with the flow velocity of 0.1-0.2m/s
It continuously is passed through 1-3 DEG C of cooling water, while starting blower, the wind of 0.2-0.3m/s speed is passed through to air inlet, wind enters second
In cavity and the first cavity；
(2) the melten glass liquid that 1300~1600 DEG C are injected into the forming cavity of pattern, after pouring, covers the 4th graphite
Alkene plate and upper mold wait the molding of melten glass liquid；
(3) after 15-20min, blower is closed, stops divulging information into air inlet, be simultaneously stopped into water cooling through-hole and lead to cooling
Water opens aspiration pump, and aspiration pump extracts the air in the first cavity and the second cavity out, so that producing in the first cavity and the second cavity
Raw negative pressure, and then move the second graphene board, third graphene board into the first cavity, the second cavity respectively, remove the 4th
Graphene board and upper mold, can be well on demoulding.
The advantages of this programme is: 1, the temperature of melten glass liquid is 1300-1600 DEG C, and graphene fusing point is up to 3652
DEG C, high temperature resistant, the pattern made of grapheme material has fabulous thermal stability and chemical stability, and then improves mold
Service life；2, graphene is that the material of maximum intensity, internal carbon are with hexagon cellular in the world so far
What shape was arranged regularly, therefore, mould structure intensity can be improved in the pattern made of grapheme material, and then can be better
Accommodate the melten glass liquid of injection；3, aspiration pump is started after the molding of melten glass liquid by setting aspiration pump, is evacuated pumping
Air in first cavity and the second cavity out makes to form negative pressure in the first cavity and the second cavity, under atmospheric pressure,
Atmospheric pressure pushes the second graphene board and third graphene board to move respectively into the first cavity, the second cavity, makes the second graphite
Alkene plate and third graphene board separate with formed glass and generate gap, and then glass two sides are not contacted with mold, and mold is not
Glass two sides can be caused to squeeze, to can realize that glass easily demoulds；4, melten glass liquid is in the in-molded 15- of type
It is demoulded after 20min, in this time, melten glass liquid is preferably formed in pattern, since pattern is graphene material
Made of material, graphene has smooth property, so that pattern surface is smooth, and then can make the glass surface after demoulding smooth, mentions
High glass finished-product quality；5, in the higher situation of melten glass liquid temperature, it is cooling that 1-3 DEG C of water is passed through in bed die and upper mold
More preferable than the effect of ventilating and cooling, the cooling water of this temperature range can quickly cool down melten glass liquid, it is easier to take away
Amount of heat, and then the cooling time of melten glass liquid is shortened, accelerate glass shaping speed, improves working efficiency.
Further, in forming step, water cooling through-hole is in asymptotic expression arc, is located at the center of bed die and upper mold, and
Maximum curvature in the middle part of water cooling through-hole is gradually reduced from the curvature on middle part both sides in the horizontal direction.It can accelerate melting in forming cavity
The radiating rate in glass metal centre, optimizes temperature gradient, avoids the generation of center thermal-arrest, at the same do not influence bed die and
The heat dissipation in other regions of upper mold；Since melten glass liquid is gradually cast in forming cavity from bottom to up, thus melten glass liquid
Temperature gradually rises from the bottom to top, when divulging information to air inlet, cooling degree that the melten glass liquid of forming cavity bottom can be made to be subject to
Less than the melten glass liquid at top, guarantee that the equilibrium of melten glass liquid in casting process is cooling.
Further, in forming step, the first cavity, the second cavity width be gradually increased from the bottom to top.
Further, in batching step, by 70~80 parts of sand, 8~10 parts of lime stone, 12~14 parts of feldspar, soda ash 6~
8 parts, 1~2 part of boric acid are uniformly mixed as glass raw material.This raw material is the primary raw material of glass production, and materials are convenient, is generally made
With.
Further, in melting step, glass raw material is melted in kiln pond, and glass melting temperature is at 1300~1600 DEG C.It will match
Good glass raw material is heated at high temperature in the range of this glass melting temperature, can form the melten glass liquid of uniform bubble-free.
