The invention has the advantages that the mould has low price, convenient use and difficult deformation, and the resin condensate produced by the mould has uniform thickness and convenient demoulding.
Description
Technical field
The present invention relates to a kind of preparation method of the mould for resin solidification.
Background technology
Mould is the shaping important device of resin solidification, directly affects outward appearance and the performance of resin cured matter.For small-scale test, simplicity of design, a mould that is with low cost, that be easy to process seem most important.At present, the mould that researcher commonly uses has metal die and Teflon mold.The usual processing cost of metal die is higher, perishable, runs into demoulding difficulty sometimes, and the meeting buckling deformation under 200 DEG C of high temperature of general Teflon mold, affect the quality of cured article.
Summary of the invention
The object of the invention is to: one is to provide a kind of cheap, easy to use, on-deformable mould making method; Two are to provide a kind of injection molding solidifies the injection molding method that the resin cured matter thickness obtained is even, be convenient in demoulding.
For achieving the above object, the present invention adopts following technical scheme:
For a preparation method for the mould of resin solidification, comprise the following steps:
Choose the two blocks of plate glass varied in size, the one side of described massive plate glass and the one side of tablet glass are applied vacuum silicon grease respectively, and spreads to transparent lamina with clean glass bar;
Choose cuboid framework, the interior angle of cuboid framework is fillet, grows up in the length of massive plate glass in cuboid framework, and the inner width of cuboid framework is less than the width of tablet glass, the inner side coating vacuum silicon grease of cuboid framework, and spread to transparent lamina with clean glass bar;
Massive plate glass is placed on the one side of cuboid framework, and tablet glass is placed on the another side of the opposed cuboid framework with massive plate glass;
Choose the long-tail ticket holder that large ting model is identical, form mould with long-tail ticket holder by fixing to massive plate glass, tablet glass and cuboid framework.
This mould only needs two blocks of plate glass, a cuboid framework and some long-tail ticket holders namely to can be made into, and it is simple and easy, convenient to make, and can reuse.In addition, vacuum silicon grease is coated with in the inner side of the one side of massive plate glass, the one side of tablet glass and cuboid framework.Vacuum silicon grease is skim, plays the effect by resin and plate glass isolation, facilitates the resin demoulding.If do not apply vacuum silicon grease, can cause demoulding difficulty on the one hand, even plate glass breaks; Can leak gas between plate glass and cuboid framework gap on the other hand, have air pocket when resin vacuumizing and exhausting and generate, thus cause resin uneven.
As improvement of the present invention, described massive plate glass long 115 ~ 120 ㎜, wide 95 ~ 110 ㎜, thick 2 ~ 4 ㎜; Described tablet glass is long and wide is 95 ~ 110 ㎜, thick 2 ~ 4 ㎜.
This size can make massive plate glass and tablet glass cover on the opposed two sides of cuboid framework, and massive plate glass cover on cuboid framework after length longer than the length of tablet glass cover on cuboid framework, facilitate injection molding.
As improvement of the present invention, the model of described long-tail ticket holder and size are No. 2 41 ㎜.
Clamping dynamics is identical on the one hand for the long-tail ticket holder of same model, and the length of tail too on the other hand, and stress equalization when being convenient to supporting mould, maintains the balance and stability of mould.
As improvement of the present invention, the material of described cuboid framework is aluminium alloy.
The cuboid framework of aluminium alloy is high temperature resistant, high pressure, heat conduction soon, not yielding.
As a further improvement on the present invention, the quantity of described long-tail ticket holder is 6, and 6 long-tail ticket holders are distributed on both sides and the bottom of described mould.
Both sides respectively arrange 2 long-tail ticket holders can guarantee that relative sliding is less likely to occur for two blocks of plate glass and cuboid framework, 2 long-tail ticket holders that bottom is arranged can guarantee that two blocks of plate glass and cuboid framework relative sliding do not occur on the one hand, can maintain the equilibrium of mould on the other hand with stable in the injection molding later stage.
For realizing the second object of the present invention, the invention provides a kind of method with above-mentioned mould injection molding, comprising the following steps:
The described mould fixed is placed in vacuum drying chamber, and vacuumizes at 90-240 DEG C;
By described mold tilt, make tablet glass surface facing to operator;
After injection molding completes, the tail central shoring of 2 of mold bottom long-tail ticket holders is opened, keep the balance of mould and stablize.
Drying box is vacuumized at 90-240 DEG C the air can got rid of in two blocks of plate glass and aluminum alloy frame gap, make to fit between plate glass and aluminum alloy frame tightr, simultaneously, the inner side of the one side of massive plate glass, the one side of tablet glass and cuboid framework all applies vacuum silicon grease and is conducive to the resin demoulding, and in this temperature range, silicone grease is non-volatile.
In sum, the invention has the beneficial effects as follows, Die price is cheap, easy to use, not yielding, and the resin cured matter thickness obtained with this mould evenly and be convenient in demoulding.

Fig. 1 is parts schematic diagram of the present invention.
Fig. 2 is mould schematic diagram of the present invention.
Detailed description of the invention
For a better understanding of the present invention, below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
As depicted in figs. 1 and 2, the preparation method of a kind of mould for resin solidification of the present invention, comprises the following steps:
1, ordinary plate glass two pieces is selected: the size of glass: the large long 115-120mm of glass, wide 95-110mm, thick 2-4mm; Little glass is long and wide is 95 ~ 110mm, thick 2 ~ 4mm.
2, aluminium alloy Thick 4 ~ 7mm, outer wide 95 ~ 110mm, foreign minister 150 ~ 170mm, interior length 110 ~ 130mm, inner width 50 ~ 70mm, the wide 18 ~ 22mm of frame.The interior angle of aluminum alloy frame is fillet, is convenient to apply vacuum silicon grease.
3, the one side of the one side of large glass and little glass is applied vacuum silicon grease, and spread to transparent lamina with clean glass bar; In addition, the inner side of aluminum alloy frame uses the same method coating vacuum silicon grease.
4, make this cover of this face of large vitreous coating vacuum silicon grease and little vitreous coating vacuum silicon grease on the opposed two sides of aluminum alloy frame, and the frame of three is alignd, then with the long-tail ticket holder that model and size are No. 2 41mm, aluminum alloy frame is fixed between layer glass.
5, the mould fixed is placed in vacuum drying chamber, vacuumizes at 90-240 DEG C, get rid of the air in glass plate and aluminum alloy frame gap; By mold tilt during injection molding, little glass-board surface is facing to operator.
Empty mould vacuumizes at 90-240 DEG C, silicone grease mobility can be allowed to strengthen on the one hand, fills the gap of aluminum alloy frame and glass, and in this temperature range, silicone grease is non-volatile on the other hand.When injection molding, mould is tilted to facilitate injection moulding operation a little.Resin can not fill, from the distance having about 1cm suitable for reading.
6, after injection molding, the tail ring of long-tail ticket holder is supported, keep the balance and stability of mould.
