Description
Technical field
The utility model relates to a kind of injection mold, and more particularly, it relates to a kind of injection nozzle of injection mold.
Background technology
Injection mold is a kind of instrument of producing injection-molded item, is also the instrument of giving injection-molded item complete structure and accurate dimension.
In the process of injection moulding; often can there is flash phenomenon in the head position in injection nozzle; this is mainly because in the process of injection moulding; the very high plastics viscosity that makes of machine barrel, nozzle temperature declines; mobility increases, and in the time that the work-piece cools in die cavity is solidified, the temperature of the plastic liquid of close injection nozzle part is still quite high; curing rate will be slower than other parts of workpiece, and when this just makes die sinking, workpiece is near the part generation flash of injection nozzle head.
Be directed to this problem, in prior art, a kind of injection mold injection nozzle register is disclosed in Chinese utility model patent prospectus 201120485157.X, for solving flash and the wire-drawing technology problem at injection nozzle place, its formation comprises temperature adjustment water jacket, hydraulic-pressure regulating valve, water temperature meter and temperature adjustment water route, described temperature adjustment water jacket is sleeved on the outside of injection nozzle, be fixedly mounted in stationary mould for mould template, be provided with into water helicla flute and water outlet helicla flute in temperature adjustment water jacket inside, both communicate in temperature adjustment water jacket bottom, in temperature adjustment water jacket bottom surface, temperature adjustment water jacket and temperature adjustment water route connecting portion are equipped with O-ring seal.Adopt this register can effectively promote injecting products quality, avoid the waste of raw materials that causes because of flash in production process, reduce injection nozzle wire drawing, accelerate injection mo(u)lding productive temp.
But, injection mold in above-mentioned patent, although the junction at injection nozzle and injection mold seals by sealing ring, but because the injection orifice position of injection nozzle does not seal, liquid in die cavity can pour in injection nozzle on a small quantity, be attached to the inwall of injection nozzle, cause slight flash phenomenon can occur.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of injection orifice to be sealed by push rod for the above-mentioned state of the art, thereby avoids the injection nozzle of the injection mold that flash occurs.
For achieving the above object, the utility model provides following technical scheme:
A kind of injection nozzle of injection mold, be arranged on injection mold, described injection mold comprises cover half and the dynamic model that can separate or close up with described cover half, described dynamic model and cover half are formed with die cavity in the time closing up, described injection nozzle is fixed on dynamic model and can be communicated with described die cavity, in described dynamic model, be provided with injection nozzle register, described injection nozzle register is wrapped in outside described injection nozzle, wherein, on described dynamic model, be fixed with oil cylinder, on described oil cylinder, be connected with push rod, one end of described push rod is plugged in injection nozzle, in described injection nozzle, offer injection orifice, and one end that described push rod is plugged in injection nozzle can be by described injection orifice sealing.
As preferably, described injection nozzle inside is formed with draw-in groove along described injection orifice peripheral, oblique, described push rod is plugged on the end of one end in injection nozzle and is formed with the projection matching with described draw-in groove, and described push rod was plugged in described injection nozzle by described projection and coordinating of described draw-in groove.
As improvement, the end that described push rod is plugged in one end in injection nozzle can seal described injection orifice.
Compared with prior art, the utility model has the advantage of: on dynamic model, be provided with oil cylinder, move back and forth in injection nozzle by hydraulic oil cylinder driving push rod, thereby can by hydraulic oil cylinder driving push rod, injection orifice be sealed at the latter end of injection technique, prevent that the parenteral solution in die cavity is back to generation flash in injection nozzle.

The specific embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As Figure 1-Figure 5, the present embodiment is a kind of injection nozzle 1 of injection mold, be arranged on injection mold, described injection mold comprises cover half 2 and the dynamic model 3 that can separate or close up with described cover half, concrete, on cover half, being provided with guide pillar, dynamic model is set on guide pillar and can slides along guide pillar, on cover half, be provided with a retaining mechanism, dynamic model and cover half can be locked together firmly.
Described dynamic model and cover half are formed with die cavity 4 in the time closing up, described injection nozzle is fixed on dynamic model, and can be communicated with described die cavity, the head of injection nozzle offers injection orifice, and the position of injection orifice is opened on the inwall of die cavity and is concordant with the mould intracavity wall around this injection orifice.
In described dynamic model, be provided with injection nozzle register 5, described injection nozzle register is wrapped in outside described injection nozzle, water inlet helicla flute and water outlet helicla flute are comprised, above-mentioned water inlet helicla flute and water outlet helicla flute converge at the head of injection nozzle, between injection nozzle register and mould, be fixed with sealing ring, prevent that the high-temp liquid in die cavity from infiltrating register.Just start, in the time of injection high temperature plastics liquid, register is not first worked, by the time after having injected, toward input cold water in register, because register is wrapped in the outer ring of injection nozzle, thereby injection nozzle is lowered the temperature, make it approach and synchronize with the cooling rate of workpiece in die cavity, prevent that workpiece from, because heated parts is even, flash occurring in the time of die sinking.
