Abstract
The utility model discloses a lengthened nozzle head with a heater of an injection molding machine, which comprises a nozzle body. The nozzle body is provided with a feed inlet and a discharge outlet which are communicated with each other, external threads are arranged at the end with the feed inlet of the nozzle body, a spiral groove is disposed on the outer surface of the nozzle body, a heating coil is embedded in the groove, and a temperature sensing device is arranged in the heating coil. The heating coil is embedded in the groove of the outer surface of the nozzle body, three surfaces of the heating coil are attached to the nozzle body, and heating performance of the heating coil is greatly improved. Simultaneously, the temperature sensing device is disposed in the heating coil, and the temperature of the nozzle head can be accurately controlled by the aid of control of the temperature sensing device to the heating coil. In addition, the heating coil is embedded in the groove, the outer surface of the heating coil is level with the outer surface of the nozzle body, and accordingly injection molding materials adhered on the nozzle head can be easily cleaned.
Description
Technical field
The utility model relates to a kind of injection machine nozzle head, relates to a kind of extended type injection machine nozzle head with heater specifically.
Background technology
Existing injection machine has a nozzle head usually, and injection molding material injects in mould or the hot runner manifold by nozzle head, and existing injection machine nozzle head is shorter usually.When the making of some big moulding, when needing probe into nozzle head in mould or the hot runner manifold, existing short injection machine nozzle head need extend.But when adopting existing extended type injection machine nozzle head, injection molding material is understood some heat and is distributed by nozzle head in the process of nozzle head of flowing through, cause the temperature of injection molding material to descend, its mobile can reduction after the injection molding material temperature descends, influenced injection moulding work, the technical scheme of existing common employing is the spring heating collar of outer surface cover at nozzle head, but the spring heating collar just simply is wrapped in the nozzle body outer surface, spring heating collar can only be by pasting mutually with the nozzle head outer surface one heats in the face of nozzle head, and the efficient of heating is lower.And the spring heating collar can only be simple nozzle head is heated, and to the heating temperature can only control by rule of thumb, can't control the temperature of nozzle head accurately.In addition, when injection molding material can be bonded on the outer surface of nozzle head after the spout of nozzle head leaks out, because the existence of spring heating collar, make to be bonded in injection molding material cleaning difficulty relatively on the nozzle head.
The utility model content
For overcoming above-mentioned defective, the utility model aims to provide a kind of can accurately heating, and can easily clear up again simultaneously to be bonded in the extended type injection machine nozzle head that leaks the band heater of injection molding material on the nozzle head outer surface.
For achieving the above object, the technical solution adopted in the utility model is: a kind of extended type injection machine nozzle head with heater, comprise nozzle body, described nozzle body has a charging aperture and discharging opening, described charging aperture and discharging opening connect, charging aperture one end of described nozzle body has external screw thread, and the outer surface of described nozzle body has spiral helicine groove, is embedded with heater coil in the described groove.
The shape of cross section of described groove is a rectangle, and the shape of cross section of described heater coil is the rectangle that is complementary with groove.
Be provided with temp-sensing device in the described heater coil.
Described nozzle body is provided with the outer-hexagonal structure near the external screw thread place.
Adopted the extended type injection machine nozzle head of band heater of the present utility model, because heater coil is embedded in the groove of nozzle body outer surface, heater coil has three faces to paste mutually with nozzle body, heating properties improves greatly, simultaneously, in heater coil, be provided with temp-sensing device,, can control the temperature of nozzle head accurately by the control of temp-sensing device to heater coil.Simultaneously, because heater coil is embedded in groove, the outer surface of heater coil is equal with the outer surface of nozzle body, can be easy to clear up the injection molding material that is bonded on the nozzle head.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a nozzle body part drawing of the present utility model.
Fig. 3 is a heater coil part drawing of the present utility model.
Among the figure: 1-nozzle body, 2-charging aperture, 3-discharging opening, 4-external screw thread, 5-groove, 6-heater coil, 7-outer-hexagonal structure.
The specific embodiment
As shown in Figure 1-Figure 3, the utility model discloses a kind of extended type injection machine nozzle head with heater, comprise nozzle body 1, described nozzle body 1 has a charging aperture 2 and discharging opening 3, described charging aperture 2 and discharging opening 3 connect, and charging aperture 2 one ends of described nozzle body 1 have external screw thread 4, and described nozzle body 1 is fixed on the injection machine by external screw thread 4, injection molding material is injected in mould or the hot runner manifold by flowing out in the charging aperture 2 flow nozzle bodies 1 and from discharging opening 3.In sum, basic identical with existing injection machine nozzle head.
The new point of innovation of the present utility model is that mainly the outer surface of described nozzle body 1 has spiral helicine groove 5, is embedded with heater coil 6 in the described groove 5.Because heater coil 6 is embedded in the groove 5, makes the heater coil 6 and the contact area of nozzle body 1 improve greatly, thereby improved the efficiency of heating surface of heater coil greatly nozzle body 1.
In the specific implementation, the shape of cross section of described groove 5 is a rectangle, and the shape of cross section of described heater coil 6 is the rectangle that is complementary with groove 5.Like this, in the time of in heater coil 6 is embedded into groove 5, the outer surface of heater coil 6 is equal with the outer surface of nozzle body 1, can be easy to clear up the injection molding material that is bonded on the nozzle head.
As a kind of optimal way of the present utility model, be provided with temp-sensing device in the described heater coil 6.Temp-sensing device is controlled the temperature of nozzle body 1 in real time, when the temperature of nozzle body 1 is lower than setting value, temp-sensing device control heater coil 6, nozzle body 1 is heated, when the temperature of nozzle body 1 was higher than setting value, temp-sensing device control heater coil 6 dead electricity stopped nozzle body 1 is heated.
Described nozzle body 1 is provided with outer-hexagonal structure 7 near external screw thread 4 places.Because nozzle body 1 is generally cylindrical structural, the main effect of outer-hexagonal structure 7 is to load onto injection machine or when injection machine is dismantled when nozzle body 1, can adopt instrument such as spanner to be enclosed within on the outer-hexagonal structure 7, makes the more laborsaving convenience of dismounting of nozzle body.Certainly, outer-hexagonal structure 7 also can adopt structures such as four jiaos or anise.
