Brief description
Fig. 1 is the principle sketch of the processing technology of the large-scale reinforced silica gel mould of the present embodiment.
Specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail it should be appreciated that these embodiments are merely to illustrate the present invention
Rather than restriction the scope of the present invention, after having read the present invention, the various equivalences to the present invention for the those skilled in the art
The modification of form all falls within the application claims limited range.
A kind of processing technology of large-scale reinforced silica gel mould, comprises the following steps：
Step one：Determine the mode of typing design to make prototype according to die needed size；Make mould and prototype
Size shape all consistent, then, also need the periphery of the prototype completing is surface-treated, that is, need the table of prototype
Face carries out polishing, paints up to smooth, then prototype is carried out, to remove surface dirt.For typing design, it includes
Vertical type design, planar designs and no typing design, for the design of vertical type typing, perimeter die week when pouring mould silica gel
Side bubble is few, and prototype is difficult to misplace, but, the taking-up of prototype is more difficult；Planar designs, periphery when pouring mould silica gel
Mold periphery bubble is few, and prototype is difficult to misplace, but, the taking-up of prototype is relatively easy to；No typing design, it is mainly used in
Bright part and rubber parts.
Then carry out step 2：Make the frame main body with the shape adaptation of prototype, when prototype is put in frame main body,
40mm-50mm is left, the height of frame main body is more than prototype highest height between the inwall of the surrounding of prototype and frame main body
50mm-200mm；
Step 3：In the detachable substrate being fixed with smooth surface of the opening of frame main body, substrate closing open end；
Step 4：Prototype is put in frame main body, and prototype is positioned on substrate；Herein, prototype is fixed with substrate；
Step 5：Prototype is fixed with the sealing member for sealing the gap between prototype and substrate, the purpose of this setting
When being in order to avoid pouring silica gel, silica gel enters between original paper and substrate；Specifically, in the present embodiment, sealing member includes glue
Band paper, glass cement, the present embodiment example utilizes the hole of some small-bores or sulculus between rubber belt sealing original paper and substrate, certainly,
Also some apertures on sealing original paper surface or sulculus, then bigbore using some between glass cement sealing original paper and substrate
Hole and bigbore groove, certainly, also sealing some macropores on original paper surface or bigbore groove are so that complete between original paper and substrate
Totally-enclosed, and make the surface of original paper smoothness higher.
Step 6：Some reinforcements are placed between prototype and frame main body；Described reinforcement can be set to and prototype
The rod member of external shape fits and/or block part；In the present embodiment, after mould molding, its side wall is embedded with reinforcement, by reinforcement
Part, can effectively improve the intensity of mould, prevent die deformation.
Step 7：Using sprayer prototype outer surface, the inner surface of frame main body and substrate towards frame main body table
Face is uniformly coated with releasing agent；In this step, releasing agent can be demoulding wax, it is of course also possible to be other materials,
As：It is notable that ingot stripper is when being sprayed, it is liquid to Tissuemat E, and, spray can preferentially be selected by sprayer
Rifle, it is of course also possible to be brushed with brush.
For ensure prototype surface quality, in the present embodiment, also need to follow the steps below, will be agitated after silica gel and
Firming agent is poured on the outer surface of prototype with thin uniform flow, forms gel coating resin with the outer surface in prototype, by gel coating resin, makes
Prototype surface more smooth so that the mould silica gel of liquid can be preferably in the fixing solidification of prototypic surface.
Step 8：After mould silica gel and firming agent are sufficiently stirred for, using vacuum equipment, application of vacuum is carried out to it；Whereby
Remove the air that mould silica gel is contained after agitation with firming agent；
Step 9：The mould silica gel after application of vacuum will be carried out and firming agent is cast in frame main body；
Step 10：At a suitable temperature cured is carried out to form mould to mould silica gel；Specifically, including room temperature
Solidification and heating cure, for cold curing, do not improve temperature when room temperature is between 25 degrees Celsius to 30 degrees Celsius, allow mould silicon
Glue spontaneous curing；If room temperature is too low or during duration tension it is necessary to heating cure, that is, improve solidification temperature, but, when solidification temperature
When degree is more than 40 degrees Celsius, mould silica gel can expand in solidification, and this can affect the shape of mould, therefore in the present embodiment, also
Side setting reinforcement or the fixed form of prototype can be deviated from frame main body, its deformation is prevented with extrusion die silica gel.
Step 11：Cut open frame main body and take out prototype, mould is formed with die cavity；
Step 12：Modify mould agnail；
Step 13：Glue running channel and steam vent are offered on mould.
In addition, before above-mentioned step 12 or step 13, also should have and other moulds in the edge in mould
For the telltale mark of positioning during tool docking matched moulds.When each mould carries out matched moulds, be conducive to quickly using telltale mark
Positioning, and can improve matched moulds docking precision, be for example mutually butted the upper die and lower die of coupling, at the connector of upper mould and under
At the connector of mould, correspondence offers telltale mark, whereby, can effectively improve the merging precision of upper die and lower die.
And, in step 13, glue running channel includes main running channel and point running channel, and described main running channel is located at mould near former
The position of type larger sectional area, described point of running channel connects main running channel and die cavity；Described steam vent be located at mould the top of die cavity,
At the dead angle of the peak of local location, turning and convex-concave.Herein, main running channel can be arranged as required to many.
Additionally, the material selection rigid material of described prototype is made, such as：ABS plastic, it is of course also possible to select other materials
Material is made, and only needs rigidity good.
Step 14：Open up waveform or zigzag parting line in die surface, and carry out a point mould along this parting line.Enter
Needed for just being very easily combined into using waveform or zigzag parting line between little mould after row point mould process
Mould, because waveform or zigzag parting line have good positioning action between the little mould of mutual assembling.
The above is only the preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-described embodiment,
All technical schemes belonging under thinking of the present invention belong to protection scope of the present invention.It should be pointed out that for the art
For those of ordinary skill, some improvements and modifications without departing from the principles of the present invention, these improvements and modifications also should
It is considered as protection scope of the present invention.
