Abstract
The utility model discloses a kind of 3D glass heats to inhale mold, including lower cavity die, and lower cavity die is equipped with the groove for accommodating glass to be processed, and bottom portion of groove is made of ventilative poromerics.Poromerics is the heat-conductive porous material of high-temperature stable.The back side of bottom portion of groove is equipped with the reinforcing rib for preventing groove from generating deformation.The utility model has technical effect that lower cavity die is only arranged in mold, and the inner concave of bend glass does not need to be contacted with mold, reduces the difficulty of subsequent inner concave polishing；Due to during its hot bending being influenced by pull of vacuum, each point of glass is stressed directly, uniform force, and brake forming consistency is good；Due to being formed using vacuum type suction pressure, mold is squeezed few, mold of the die life higher than pressing mold mode.
Description
Technical field
The utility model relates to glass processing field, in particular to a kind of 3D glass heat inhales mold.
Background technique
With weeding out the old and bring forth the new for the products such as mobile phone, tablet computer, market is for the glass panel that is covered on its screen
It is required that also higher and higher, this also just proposes increasingly higher demands to the mold for processing glass panel.And present market
Upper majority mold is that hot pressing type glass bending molds mold, and this mold is generally divided into upper male mould and lower cavity die, and when processing need to
The sheet glass of hot bending is wanted to be placed among the two, after heating, by applying certain pressure to upper male mould, in Glass Transition state
It is lower by glass according to the size die cast of mold.And this mold is in hot bending punch process, when curved workpieces, in workpiece
Between company side may occur under it is curved with it is uneven, and even side it is longer, material is thinner, and this phenomenon also can be more serious；Hot pressing simultaneously
The uniformity of control is also a problem, if the glass of molten condition will lead to shaped article thickness by non-uniform pressure
It is poor to spend dimensional uniformity.It needs to pass through since heat is when being transmitted to the glass with the mold of mould mode center at thermally conductive aspect
The thickness of upper and lower two molds can be only achieved purpose, will increase energy consumption in this way, reduce thermal conduction rate.There is this clamping system again
Making the concave and convex surface of formed glass can all contact with mold, result in the need for all carrying out subsequent polishing process to the two sides of glass
Step.And upper male mould and lower cavity die can be worn in prolonged hot pressing environment and when mould, and the gap for wearing generation may
Cause have dust on product.In addition stamping die is by hot press working when hot-forming, and the service life of groove is usually shorter, and labor and materials exist
Flow resistance in mold is larger, easily influences forming quality when bool reverse mould.Therefore it needs to develop a kind of new technology
Improve the service life of bool forming quality and mold groove.
Summary of the invention
Yields in order to solve existing hot pressing type glass bending molding mold output is low, heat transfer is bad, more than process and mould
Has service life short technical problem, the utility model provides a kind of precision that can effectively improve product, the 3D glass of production capacity and benefit
Glass heat inhales mold.
In order to achieve the above technical purposes, the technical solution of the utility model is,
A kind of 3D glass heat suction mold, including lower cavity die, the lower cavity die are equipped with for accommodating glass to be processed
Groove, the bottom portion of groove are made of ventilative poromerics.
A kind of 3D glass heat inhales mold, and the poromerics is the heat-conductive porous material of high-temperature stable.
A kind of 3D glass heat inhales mold, and the back side of the bottom portion of groove is equipped with for preventing groove from generating deformation
Reinforcing rib.
A kind of 3D glass heat inhales mold, the reinforcing rib be bottom portion of groove back side intaglio go out it is multiple tight
The edge of the polygon of solid matter column.
A kind of 3D glass heat inhales mold, at least sets that there are two grooves on the lower cavity die side by side.
The utility model has technical effect that, mold is only arranged lower cavity die, the inner concave of bend glass do not need with
Mold is contacted, and the difficulty of subsequent inner concave polishing is reduced；Due to during its hot bending being influenced by pull of vacuum, glass
Each point be stressed directly, uniform force, brake forming consistency is good；Due to using vacuum type suction pressure form, mold by
Squeeze few, mold of the die life higher than pressing mold mode.
The utility model is described in further detail with reference to the accompanying drawing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the schematic rear view of the utility model mold；
1 it is wherein groove, 2 be reinforcing rib, 3 be glass, 4 is lower cavity die
Specific embodiment
Referring to Fig. 1, lower cavity die is only arranged in the mold of the present embodiment, and lower cavity die is equipped with for accommodating the recessed of glass to be processed
Slot, bottom portion of groove are made of ventilative poromerics.In order to guarantee that heat inhales processing effect, used poromerics is that high temperature is steady
Fixed heat-conductive porous material, as graphite or other similar graphite have micropore, high thermal conductivity, high-temperature stable, such as silicon carbide
Deng achievable.
Since mold may be configured as the mobile heating on heating assembly line, multiple molds are mutually collided when moving in order to prevent
It hits and causes groove deformation and influence glass product precision, therefore be equipped at the back side of bottom portion of groove for preventing groove from generating deformation
Reinforcing rib.
In order to mold processing convenience, reinforcing rib be bottom portion of groove back side intaglio go out it is multiple compact arranged polygon
The edge of shape.As shown in Figure 1, intaglio of the present embodiment using multiple compact arranged hexagons, forms as cellular
Arrangement, with the intensity of the retaining groove shape in the case where maintaining bottom portion of groove thickness unlikely blocked up and to influence bottom suction.
Production efficiency is improved in order to realize that a mould goes out divided glass, sets that there are two recessed on the lower cavity die of the present embodiment side by side
Slot may also set up more grooves according to the actual situation.
In actual processing, this mold is not required to upper male mould hot pressing, and sheet glass passes through graphite and similar material after hot mastication
Glass heat is inhaled from bottom air-breathing and is formed by the gas permeability of material.The mold back side has cellular intaglio to form reinforcing rib, this honeycomb
Structural strength is very high, can bear multiaxis loading, and in addition weight is again very light, and permeability increases.Glass is heated to by hot plate
Glass softens rear mold bottom and inhales mold backs with vacuum breathing apparatus, makes suction through the through glass of graphite, to rise to glass
To molding effect.
