Structure a kind of full cooling of the present invention floating type nozzle comprises the main body of tubulose and the nozzle of tubulose, and the upper end of main body is the sizing material inflow entrance, the lower end of the main body hollow nut that spins; Nozzle is arranged at the lower end of main body, wherein, the outer wall of the epimere of nozzle is wedge shape and is embedded in the corresponding position of main body lower end on the vertical section, the outer wall in the stage casing of nozzle is stepped and be embedded in the corresponding position of main body lower end, the hypomere of nozzle puts in described hollow nut hollow and interlocking with it, ladder on the outer wall in the upper end of described hollow nut and the stage casing of the nozzle pressure that offsets, along with the precession of described hollow nut nozzle is formed the power that compresses upwards and make nozzle upwards near; The lower end of nozzle is the sizing material flow export; The hollow passageway from the sizing material inflow entrance to the sizing material flow export, the diameter dimension that begins downward hollow passageway from the sizing material inflow entrance diminishes gradually and has the minimum position of the diameter dimension of hollow passageway at the nozzle position, downward again, the diameter dimension of its hollow passageway becomes greatly gradually, thereby forms a bell mouth shape at the sizing material flow export; Cooling device also is set, cooling device is the closed cavity as the passage of cooling medium, described closed cavity is for being set in the interior sky that forms in week outside the main body by tubular housing, the lower end of this closed cavity reaches the corresponding relevant position of minimum position with the diameter dimension of hollow passageway.
Technique scheme is further set forth:
The upper end of shell outwards protrudes out a convex edge, and this convex edge is provided with cooling medium inlet and cooling medium outlet respectively, and the cooling medium inlet is communicated with described closed cavity by the A screw plug, and the cooling medium outlet is communicated with described closed cavity by the B screw plug.
Stage casing at nozzle is provided with disk spring, and the upper end and the main body of disk spring offset, and the outer wall of its lower end and nozzle offsets.
Lower end at nozzle is provided with seal washer, when nozzle seals when sprue bush on the runner plate contacts, to solve nozzle and sprue bush end face because of processing the leakage glue problem that out-of-flatness causes.
Cooling medium is water or liquid oils.
The invention has the beneficial effects as follows: one, nozzle are provided with cooling device, reach the corresponding relevant position of minimum position with the diameter dimension of hollow passageway as the lower end of the closed cavity of the passage of cooling medium, be near the horn mouth, cooling effect improves, by temperature sensing device data are passed to microprocessor again, after microprocessor processes, reach cooling device, operation real-time monitoring to cooling device, temperature in the nozzle is carried out real-time monitoring, make the temperature constant in the nozzle, cause sizing material sulfuration can not occur.Two, can guarantee that stub bar is brought out easily when die sinking; Three, stub bar is short, need not material thrasher, saves sizing material; Four, adopt disk spring to support between nozzle and main body, when nozzle contacted with the mould gate cover, butterfly spring was compressed, and makes the interface positiver sealing of nozzle and mould gate cover; Its five, increased seal washer at the nozzle lower end, can solve nozzle and sprue bush end face because of the leakage glue problem that causes of processing out-of-flatness.Six, be suitable for using on various types of rubber injection machines.
