Description
Technical field
The utility model relates to hot runner mould technical field, especially a kind of quick hot nozzle of colour changing type.
Background technique
Existing hot nozzle nozzle core is in forming process, and melt plastic cement passes sequentially through sprue and runner, then from discharging
Mouth sprays, and after Dang Rezui is removed, the after-hardening of internal melt plastic cement cooling is easy to block since runner is smaller, it is difficult to
It takes out, if installation heating reduces production efficiency to be discharged again, while nozzle core its unique structure causes to be difficult to inside it
It is cleaned to, in process of production, melt plastic cement has sub-fraction melt plastic cement when passing through nozzle core and is trapped in nozzle in-core, by
Higher in the temperature of nozzle core, after remaining melt plastic cement is detained longer time, high temperature can make plastic solution degrade, after degradation
Plastic cement gradually can be substituted into product in subsequent each forming process die cavity in, particularly for produce different colours modeling
It is easy to influence beauty when material products, therefore needs to clear up it when replacing the melt plastic cement of different colours, but now
Structure be difficult to be cleaned to inside it.

Defect.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of quick hot nozzle of colour changing type, including nozzle body, cast gate department and nozzle core, nozzle body axle center are equipped with sprue, and nozzle
Body one end is equipped with the placement groove placed for cast gate department and nozzle core, and the cast gate department is placed on nozzle core periphery and connect with nozzle body solid
Fixed, nozzle body periphery is successively arranged with heating coil and protective case, and the thermoelectricity stretched in nozzle body is additionally provided in the protective case
Even component, the nozzle core include the fastening part and interconnecting piece being threadedly coupled, and fastening part axle center is equipped with the auxiliary being connected to sprue
Runner, and it is equipped with annular protrusion close to one end of sprue, which is equipped with equally distributed holding notch, and interconnecting piece is close
One end of fastening part is equipped with the groove of point leading matched with auxiliary flow, and the other end is provided with the sharp block of guiding, and it is close point to lead groove
Sharp block one end is oriented to be equipped with towards the runner for being oriented to sharp block surface setting.
Nozzle body is provided with metallic packing ring far from one end of nozzle core.
The inclination angle that auxiliary flow is equipped with close to one end of sprue and sprue matches.
The runner is provided at least three around interconnecting piece axle center.
By adopting the above-described technical solution, a kind of quick hot nozzle of colour changing type, is conveniently dismantled by the structure setting of nozzle core
Clout inside taking out, and clears up it, and the utility model structure is simple, easy for installation, effective solution nozzle in-core
The taking-up of clout and the problem being difficult to clean.
