Further, the injection channel outer wall is set side by side with polylith spoiler along injection channel length direction, described to disturb
Flowing plate is hinged with injection channel outer wall, and spoiler side is connect by the tension spring being obliquely installed with injection channel.
Beneficial effects of the present invention：The rubber ring injection molding system of the present invention, including rubber loop mould and injection molding machine, institute
It includes formation die core to state rubber loop mould, and cavity is offered in the formation die core, open top is offered at the top of formation die core
And the material buffer chamber being connected to cavity by feeding-passage, the material buffer intracavitary are provided with to seal with material buffer chamber and slide
The pressing plate of dynamic connection, the pressing plate are connect by tension spring with material buffer bottom of chamber portion, and the discharge port of the injection molding machine passes through injection molding
Channel is connected to material buffer chamber.It is poor to solve rubber loop mould discharge stability for the rubber ring injection molding system of the structure
The problem of, it effectively prevents rubber and extremely expects, misrun, chokes with resentment phenomena such as bad, improve Forming Quality and the production of rubber ring product
Efficiency.
Description of the drawings
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the schematic diagram of the present invention.
Specific implementation mode
Below with reference to attached drawing, the present invention is described in detail, as shown in Figure 1：The rubber ring injection molding of the present embodiment
System, including rubber loop mould and injection molding machine 1, the rubber loop mould include formation die core 2, are offered in the formation die core
Cavity 3, cavity are annular groove-shaped, the molding mold that formation die core is made of upper mold and lower mold, the type of the upper mold
The cavity of chamber and lower mold is symmetrical arranged or the formation die core is a single mode mold for carrying concavity cavity, this implementation
In example, the molding mold that formation die core is made of upper mold and lower mold, the cavity of upper mold and the cavity of lower mold are symmetrical
Setting, the cavity of upper mold are formed in the lower surface of upper mold, and the cavity of lower mold is formed in the upper surface of lower mold, upper mold
It is fitted together using the positioning of guide post guide sleeve fit system with lower mold；Offer at the top of formation die core open top and by into
The material buffer chamber 4 that material channel is connected to cavity, the material buffer intracavitary is provided with to be slidably connected with the sealing of material buffer chamber
Pressing plate 5, the pressing plate connect by tension spring 6 with material buffer bottom of chamber portion, and the discharge port of the injection molding machine passes through injection channel 7
It is connected to material buffer chamber, specifically, in formation die core offers the guide channel being connected to material buffer chamber, the injection molding
Channel is connected to guide channel.In forming process, injection molding machine buffers after so that rubber raw materials is melted through injection channel injecting material
Chamber then flows into cavity by feeding-passage again, and during material injects cavity by material buffer chamber, tension spring tenses pressure
Plate, making pressing plate always has the tendency that being pressed down against, and to form extruding force to material in real time, is conducive to raising material and enters cavity
Rate and uniformity, solve the problems, such as that rubber loop mould discharge stability is poor, effectively prevent rubber extremely expect, misrun, nest
Phenomena such as gas is bad improves the Forming Quality and production efficiency of rubber ring product.
It is further improved as to above-mentioned technical proposal, the pumping vertically extended is offered in the formation die core
Channel 8 is inhaled, the suction channel is connected to by exhaust passage 9 with cavity, and the junction of the exhaust passage and cavity is provided with
Filtering baffle 10, filtering baffle are avoided that liquid rubber fluid flows into exhaust passage, are provided with piston 11 in suction channel, are molded
Fixed pulley 13 is provided with by holder 12 at the top of mold core, further includes drawstring 14, described drawstring one end is connect with pressing plate, the other end around
It is connect with piston after crossing fixed pulley.As material gradually injects cavity, pressing plate gradually moves down, by drawstring pull piston gradually on
It moves, to generate swabbing action, on the one hand, the air in material or in cavity can be extracted out, further avoid phenomenon of choking with resentment；
On the other hand, the flow velocity that can further increase material, makes material quickly fill with cavity, to improve production efficiency.
It is further improved as to above-mentioned technical proposal, having heaters 15 is set in the injection channel.Melting state
The heated device of rubber heat again, delayed solidification time, further avoid the appearance that rubber is extremely expected.
It is further improved as to above-mentioned technical proposal, insulating layer 16, insulating layer is enclosed with outside the injection channel
With insulation effect, it is avoided that rubber solidifies in injection channel.
It is further improved as to above-mentioned technical proposal, heating chamber is formed between the insulating layer and injection channel outer wall
17, further include the steam circulation 18 with heating strong continune, steam circulation includes steam generator, jet chimney and valve
Door etc. is the prior art, is not described in detail here.The rubber flow in injection channel is heated by steam circulation, it can be into one
Step delays the time that rubber solidifies.
It is further improved as to above-mentioned technical proposal, the injection channel outer wall is arranged side by side along injection channel length direction
It is provided with polylith spoiler 19, the spoiler is hinged with injection channel outer wall, and spoiler side passes through the tension spring that is obliquely installed
It is connect with injection channel.During steam stream heated chamber, spoiler just has barrier effect, only pressure to reach steam stream
When to a certain extent, spoiler can just be turned to around hinge joint tends to horizontality, so that steam stream is largely flowed through, that is, passes through flow-disturbing
Plate extends the time of the heated chamber of steam stream, to improve heat effect of the steam to rubber flow.
Finally illustrate, the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although with reference to compared with
Good embodiment describes the invention in detail, it will be understood by those of ordinary skill in the art that, it can be to the skill of the present invention
Art scheme is modified or replaced equivalently, and without departing from the objective and range of technical solution of the present invention, should all be covered at this
In the right of invention.
