Technical field
The invention belongs to mechanical pressing mold field, and in particular to a kind of silica gel mould pressing process.
Background technology
Silica gel mould pressing process is used to produce in enormous quantities, and mould investment is relatively costly.In the case where demand is very small, mistake
Mould investment high can cause the increase of R＆D costs.For baroque workpiece, such as S-shaped workpiece, using traditional mould
Pressure technique, the production process of design and the molding of mould is all very complicated.
The content of the invention
In order to solve the above mentioned problem of prior art presence, the invention provides a kind of simple silica gel molding of production process
Technique.
To realize object above, the technical solution adopted in the present invention is：A kind of silica gel mould pressing process is comprised the following steps：
Contour structures according to required product make mould；Internal structure according to required product makes core rod；By core rod assembling in mould
In tool；In the mould that silica gel injection is assembled；Mould to being marked with silica gel is vacuumized；Mould is solidified, is heated；
Die sinking obtains the required product with core rod；Removal core rod, obtains required product.
Further, the mould includes upper die and lower die, and the upper die and lower die combine the mould of composition
The inside of tool is a cavity, and the cavity is identical with the contour structures of the required product.
Further, the size of the core rod and the inside dimension of required product are identical.
Further, the time that the described pair of mould for being marked with silica gel is vacuumized is 10min.
Further, the temperature heated to mould is set as 60 DEG C, and warm-up time is set as 90min.
Further, the required product is S-shaped silicone tube.
Further, the silica gel mould pressing process also includes carrying out grinding process to the required product surface for obtaining.
Due to using above technical scheme, beneficial effects of the present invention to be：The present invention is assembled by the core rod that will be made
In mould, to silica gel is injected in mould, the required product with core rod is obtained after die sinking, then core rod removal is obtained into required product
Product, production process of the invention is simple, practical, can help reduce R＆D costs, and can produce more complicated workpiece.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
The accompanying drawing to be used needed for having technology description is briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is a kind of flow chart of silica gel mould pressing process that one embodiment of the invention is provided.
Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, technical scheme will be carried out below
Detailed description.Obviously, described embodiment is only a part of embodiment of the invention, rather than whole embodiments.Base
Embodiment in the present invention, those of ordinary skill in the art are resulting on the premise of creative work is not made to be owned
Other embodiment, belongs to the scope that the present invention is protected.
As shown in figure 1, the invention provides a kind of silica gel mould pressing process, it is comprised the following steps：
S1, according to the contour structures of required product make mould, the mould include upper die and lower die.Upper die and lower die are combined
The mould inside for constituting together is a cavity, and the size of the cavity is identical with the appearance and size of required product.
S2, according to the internal structure of required product make core rod.The inside dimension phase of the size of the core rod and required product
Together.
S3, by core rod assembling in a mold, it is specially：By core rod assembling in lower mould.
In S4, the mould for assembling silica gel injection, it is specially：Note to being equipped with the upper die and lower die of core rod respectively
Enter silica gel.
S5, the mould to being marked with silica gel are vacuumized, and it is specially：The upper die and lower die that silica gel will be marked with are put into vacuum
Vacuumized in machine, the pumpdown time is set as 10min.
S6, mould is solidified, is heated, it is specially：
Upper die and lower die after vacuumizing carry out matched moulds, solidification, heating.Wherein, the temperature of heating is set as 60 DEG C, plus
The warm time is set as 90min.
S7, the mould after heating is molded, obtain the required product with core rod.
S8, removal core rod, obtain required product.
Below as a example by producing S-shaped silicone tube, silica gel mould pressing process of the present invention is described in detail.
Mould is made using the three-dimensional data of the contour structures of S-shaped silicone tube product, and the mould is polished, until
The mould inside and outside are smooth.
Core rod is made using the three-dimensional data of the internal structure of S-shaped silicone tube product, and the core rod is polished, until
The core rod exterior finish is smooth.
By core rod assembling in a mold, and mould and core rod are debugged, it is ensured that the sealing of mould and its inside
Slickness.
In the mould that silica gel injection is assembled, and mould is vacuumized, solidified, heated.
Mould is opened, the S-shaped silicone tube with core rod is taken out.
The core rod in S-shaped silicone tube is taken out, S-shaped silicone tube is obtained.
Surface to S-shaped silicone tube carries out the post processing such as polish.
