Further, the suction channel extended along the vertical direction is offered in the formation die core, the suction channel passes through Exhaust passage is connected to type chamber, and the junction of the exhaust passage and type chamber is provided with filtering baffle, is provided in suction channel Piston, formation die core top are provided with fixed pulley by bracket, further include drawstring, described drawstring one end is connect with pressing plate, another End is connect after bypassing fixed pulley with piston.

Further, having heaters is set in the injection channel.

Further, insulating layer is enclosed with outside the injection channel.

Further, heating chamber is formed between the insulating layer and injection channel outer wall, further includes the steaming being connected to heating chamber Steam circulation system.

Further, the injection channel outer wall is set side by side with muti-piece spoiler along injection channel length direction, described to disturb Flowing plate and injection channel outer wall are hinged, and spoiler side passes through the tension spring being obliquely installed and connect with injection channel.

The beneficial effects of the utility model：The rubber ring injection molding system of the utility model, including rubber loop mould and Injection molding machine, the rubber loop mould include formation die core, and type chamber is offered in the formation die core, is offered at the top of formation die core Top opening and the material buffer chamber being connected to type chamber by feeding-passage, the material buffer is intracavitary to be provided with and material buffer Chamber seals the pressing plate being slidably connected, and the pressing plate is connect by tension spring with material buffer bottom of chamber portion, the discharge port of the injection molding machine It is connected to by injection channel with material buffer chamber.The rubber ring injection molding system of the structure, solves rubber loop mould discharge The problem of stability difference effectively prevents rubber and extremely expects, misrun, chokes with resentment phenomena such as bad, improves the molding matter of rubber ring product Amount and production efficiency.

Detailed description of the invention

The utility model is further described with reference to the accompanying drawings and examples.

Fig. 1 is the schematic diagram of the utility model.

Specific embodiment

The utility model is described in detail below with reference to attached drawing, as shown in Figure 1：The rubber ring of the present embodiment is molded Formation system, including rubber loop mould and injection molding machine 1, the rubber loop mould include formation die core 2, are opened in the formation die core Equipped with type chamber 3, type chamber is annular groove-shaped, the molding mold that formation die core is made of upper mold and lower mold, the upper mold Type chamber and the type chamber of lower mold be symmetrical arranged or the formation die core is the single mode mold for having concavity type chamber, this In embodiment, the molding mold that formation die core is made of upper mold and lower mold, the type chamber of the type chamber of upper mold and lower mold It being symmetrical arranged, the type chamber of upper mold is formed in the lower surface of upper mold, and the type chamber of lower mold is formed in the upper surface of lower mold, on Mold is fitted together with lower mold using the positioning of guide post guide sleeve fit system；Top opening is offered at the top of formation die core and is led to The material buffer chamber 4 that feeding-passage is connected to type chamber is crossed, intracavitary be provided with of the material buffer seals sliding with material buffer chamber The pressing plate 5 of connection, the pressing plate are connect by tension spring 6 with material buffer bottom of chamber portion, and the discharge port of the injection molding machine passes through injection molding Channel 7 is connected to material buffer chamber, specifically, in formation die core offers the material guide channel being connected to material buffer chamber, institute Injection channel is stated to be connected to material guide channel.In forming process, injection molding machine make rubber raw materials melt after through injection channel infusion Expect cushion chamber, then again by feeding-passage inflow type chamber, during material is by material buffer chamber injection type chamber, tension spring is drawn Press plate, pressing plate is made to have the tendency that being pressed down against always, to form extruding force to material in real time, is conducive to improve material entrance The rate and uniformity of type chamber solve the problems, such as that rubber loop mould discharge stability is poor, effectively prevent rubber and extremely expect, lack Meat is choked with resentment phenomena such as bad, and the Forming Quality and production efficiency of rubber ring product are improved.

As further improvement to above-mentioned technical proposal, the pumping extended along the vertical direction is offered in the formation die core Channel 8 is inhaled, the suction channel is connected to by exhaust passage 9 with type chamber, and the junction of the exhaust passage and type chamber 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, form Fixed pulley 13 is provided with by bracket 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 after crossing fixed pulley with piston.As gradually injection type chamber, pressing plate gradually move down material, by drawstring pull piston gradually on It moves, to generate swabbing action, on the one hand, the air in material or in type chamber can be extracted out, further avoid phenomenon of choking with resentment； On the other hand, the flow velocity that can be further improved material makes material quickly fill with type chamber, to improve production efficiency.

As further improvement 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.

As further improvement to above-mentioned technical proposal, insulating layer 16, insulating layer are enclosed with outside the injection channel With insulation effect, it is avoided that rubber solidifies in injection channel.

As further improvement to above-mentioned technical proposal, heating chamber is formed between the insulating layer and injection channel outer wall 17, it further include the steam circulation 18 being connected to heating chamber, 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 The time that step delays rubber to solidify.

As further improvement to above-mentioned technical proposal, the injection channel outer wall is arranged side by side along injection channel length direction It is provided with muti-piece spoiler 19, the spoiler and injection channel outer wall are hinged, and spoiler side passes through the tension spring being obliquely installed It is connect with injection channel.During steam stream heated chamber, spoiler just has barrier effect to steam stream, and only pressure reaches When to a certain extent, spoiler can just be turned to around hinge joint tends to horizontality, flows through steam stream largely, that is, passes through flow-disturbing Plate extends the time of the heated chamber of steam stream, to improve steam to the heat effect of rubber flow.

Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng The utility model is described in detail according to preferred embodiment, those skilled in the art should understand that, it can be to this The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model It encloses, should all cover in the scope of the claims of the utility model.
