Abstract
The utility model discloses a nozzle body with a heating sleeve. The nozzle body with a heating sleeve comprises a nozzle body and the heating sleeve, a male thread is arranged outside one end of the nozzle body, a channel hole and an installation screw are arranged in the nozzle body, the heating sleeve is sleeved in the circumference of the nozzle body, a helical wire duct is arranged in the circumference of the heating sleeve, heating strips coil in the wire duct, and the height of each of the heating strips is less than the depth of the wire duct. A concave long slot is axially arranged in the circumference of the nozzle body, a thermocouple is arranged in the concave long slot, and the diameter of the thermocouple is less than the depth of the concave long slot. A gap for the pass-through of the thermocouple is arranged at one end of the heating sleeve. The heating sleeve is axially positioned on the nozzle body by a fastening screw. The nozzle body with the heating sleeve has a simple structure and is convenient to main; and the heating sleeve is dismounted and the heating strips are replaced or a new heating sleeve with heating strips is directly used for replacing without dismounting the nozzle body from a die when the heating strips on the nozzle body are damaged and are replaced, so the operation is simple, and the labor and the time are saved.
Description
Technical field
The utility model relates to the hot-runner nozzle technical field, specifically a kind of nozzle body with heating jacket.
Background technology
Existing for the nozzle body on the hot-runner nozzle of injection mold, generally all adopt integral structure, namely have the spiral helicine wire casing of tool at the nozzle body cylindrical, coiling fire-bar in the wire casing, on an end cylindrical of nozzle body, also have a blind hole, the head of thermocouple is located in the blind hole, and thermocouple integral body is fixed on the nozzle body cylindrical by the band colligation.When the nozzle body of this integral structure needs to change when the fire-bar damage, must unload nozzle body from mould, remove the thermocouple of tying up on nozzle body, then the fire-bar of handing over professional operative employee more to renew, again nozzle body is contained on the mould, and installs thermocouple and fix with the band colligation, maintain and replace is very inconvenient, time-consuming, impact is produced.
The utility model content
Technical problem to be solved in the utility model is to overcome the defective that above-mentioned prior art exists, and a kind of nozzle body with heating jacket easy to maintenance is provided.
For this reason, the utility model adopts following technical scheme: a kind of nozzle body with heating jacket, comprise nozzle body and heating jacket, one end outside of described nozzle body is provided with external screw thread, the inside of nozzle body has runner hole and installation screw, and cover has heating jacket on the cylindrical of described nozzle body, has the spiral helicine wire casing of tool on the cylindrical of described heating jacket, coiling fire-bar in the described wire casing, the height of described fire-bar is less than the degree of depth of wire casing.
As preferentially, axially have a concave elongated on the cylindrical of described nozzle body, in the described concave elongated thermocouple is housed, the diameter of described thermocouple is less than the degree of depth of concave elongated.
As preferentially, an end of described heating jacket has a U-shaped breach.
As preferentially, described heating jacket adopts holding screw to make axial location at nozzle body.
When the damage of the fire-bar on the heating jacket needs to change, nozzle body still is contained on the nozzle body together with thermocouple, as long as unscrew holding screw, pull down heating jacket, hand over professional operative employee to change fire-bar or directly change the new heating jacket with fire-bar, then tighten holding screw, plugged, can resume production, maintain and replace is very convenient.
The beneficial effects of the utility model are: simple in structure, easy to maintenance, be used for hot-runner nozzle, when the damage of the fire-bar on the nozzle body needs to change, nozzle body need not to unload from mould, change fire-bar or directly change the new heating jacket with fire-bar as long as pull down heating jacket, easy and simple to handle, saving of work and time.

The specific embodiment
Such as Fig. 1 to a kind of nozzle body with heating jacket shown in Figure 5, comprise nozzle body 1 and heating jacket 2, one end outside of nozzle body 1 is provided with external screw thread 9, the inside of nozzle body 1 has runner hole 7 and installation screw 8, cover has heating jacket 2 on the cylindrical of nozzle body 1, the cylindrical of heating jacket 2 is provided with the spiral helicine wire casing 10 of tool, wire casing 10 interior coiling fire-bars 3, and the height of fire-bar 3 is less than the degree of depth of wire casing 10.
Axially have a concave elongated 6 on the cylindrical of nozzle body 1, thermocouple 4 is housed in the concave elongated 6, the diameter of thermocouple 4 is less than the degree of depth of concave elongated 6.
Heating jacket 2 adopts holding screw 5 to make axial location at nozzle body 1.Because assembly technology needs, can bending pass through heating jacket 2 for guaranteeing thermocouple 4, an end of described heating jacket 2 has a U-shaped breach 11.
The utility model is simple in structure, easy to maintenance, when fire-bar 3 damages on the nozzle body 1 need to change, nozzle body 1 need not to unload from mould, as long as unscrewing holding screw 5 pulls down heating jacket 2 replacing fire-bars 3 or directly changes the new heating jacket 2 with fire-bar 3, easy and simple to handle, saving of work and time.
