Description
Technical field
The invention belongs to injector technical field, more particularly to rubber injection machine.
Background technology
Rubber injection moulding machine, abbreviation rubber injection machine, it is the technology that rubber molded product produces.It is mainly used in rubber
The production of glue pressing, electrical apparatus insulation part, crash roll, seal, sole and industrial and mineral rain boots etc..At present, in state
It is inside and outside to have been obtained for being widely applied.
Existing rubber injection machine includes being used to convey the threaded shank of compound, the check valve in threaded shank end set,
Threaded shank is connected with discharge barrel, the end set feed nozzle of discharge barrel.Mould is then set in the lower section of feed nozzle, and compound is from spray
Material mouth is entered in mould.During conveying, the temperature of compound is not high, and can then set heating to fill in mould
Put so that compound heats up, and completes pressurize solidification work.Existing rubber injection machine does not obstruct between feed nozzle and mould
Mechanism, and can have partial blend in discharge barrel.Therefore when mould inside temperature rises, because heat transfer
Effect, produce the phenomenon of heat anti-pass so that the temperature in discharge barrel just rises therewith.This results in the compound in discharge barrel
（Mainly include rubber and sulphur）, meeting premature cure before mould is entered.
The content of the invention
The present invention is directed to deficiency of the prior art, there is provided rubber injection machine, it is simple in construction, and heat anti-pass can be avoided
And the situation for causing compound to be just cured before mould is entered occurs.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals：Rubber injection machine, including machine
, discharge barrel is provided with support, support is provided with the support, piston cylinder, the piston are provided with above the support
Cylinder, which slides, is provided with push rod, is provided with connecting portion above the discharge barrel, the connecting portion and the discharge barrel are internally provided with
Material channel, the push rod are stretched into the material channel.
In above-mentioned technical proposal, it is preferable that the mandrel ends are provided with the termination that diameter is more than the body of rod, before the termination
End is provided with centrum guide part, and the material in the material channel is discharged in the termination.
In above-mentioned technical proposal, it is preferable that the push rod afterbody is provided with the plug that diameter is more than the body of rod.
In above-mentioned technical proposal, it is preferable that the connecting portion has side charging aperture, and screw rod is provided with the side charging aperture
Portion, the threaded shank end set have check valve, and the plug blocks the side charging aperture.
In above-mentioned technical proposal, it is preferable that the support bottom is provided with baffle plate, and mould, institute are set below the baffle plate
State discharge barrel lower end and be provided with feed nozzle, the feed nozzle passes through the baffle plate to connect the mould.
It is simple in construction the invention provides a kind of technical scheme of rubber injection machine, heat anti-pass can be avoided and caused
The situation that compound has just been cured before mould is entered occurs.
Brief description of the drawings
Fig. 1 is the structural representation of existing rubber injection machine.
Fig. 2 is the structural representation of the rubber injection machine of the present invention.
Embodiment
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings：As shown in Figure 1 to Figure 2, rubber
Glue injector, including support, discharge barrel 3 being provided with support, support 61 being provided with the support, the top of support 61 is set
Piston cylinder 6 is equipped with, the piston cylinder 6, which slides, is provided with push rod 7, and the top of discharge barrel 3 is provided with connecting portion 2, the connection
Portion 2 and the discharge barrel 3 are internally provided with material channel 31, and the push rod 7 is stretched into the material channel 31.
The end set of push rod 7 has the termination 71 that diameter is more than the body of rod, and the front end of termination 71 is provided with centrum guiding
The material in the material channel 31 is discharged in portion 711, the termination 71.
The afterbody of push rod 7 is provided with the plug 72 that diameter is more than the body of rod.
The connecting portion 2 has side charging aperture 21, and threaded shank 1, the end of threaded shank 1 are provided with the side charging aperture 21
Check valve 11 is provided with, the plug 72 blocks the side charging aperture 21.
The support bottom is provided with baffle plate 5, and the lower section of baffle plate 5 sets mould, and the lower end of discharge barrel 3 is provided with spray
Expect mouth 4, the feed nozzle 4 passes through the baffle plate 5 to connect the mould.
When rubber injection machine conveys compound, the temperature of compound is substantially at 60 degree or so.Needed after mould is entered
Solidification work is carried out, now needs to heat up compound, its temperature is risen to 200 degree or so.And existing rubber injection machine
The situation of heat anti-pass can occur so that compound begins to have cured outside mould.
The present apparatus can avoid compound premature cure, particularly when composition is rubber and sulphur.The knot of the present invention
Structure can squeeze into the compound of discharge barrel 3 in mould, during so as to avoid mold temperature from raising, cause heat anti-pass so that go out
Temperature in barrel just rises therewith so that compound in the discharge barrel premature cure before mould is entered.
After dies cavity has injected enough compounds, start piston cylinder 6 and work, so as to drive push rod 7 to move.This
When, termination 71 discharges the material in material channel 31 by feed nozzle 4.Also, final termination 71 is withstood on feed nozzle 4, and
Plug 72 blocks side charging aperture 21.Therefore, there would not be mixing in the material channel 31 of this section of termination 71 and plug 72
Material.So being heated up in mould, when compound is carried out solidifying work and pressurize work, heat anti-pass would not occur and make
Obtain the situation of the compound solidification in material channel 31.
Protection scope of the present invention includes but is not limited to embodiment of above, and protection scope of the present invention is with claims
It is defined, any replacement being readily apparent that to those skilled in the art that this technology is made, deformation, improvement each fall within the present invention's
Protection domain.
It is simple in construction the invention provides a kind of technical scheme of rubber injection machine, heat anti-pass can be avoided and caused
The situation that compound has just been cured before mould is entered occurs.
