Abstract
The utility model relates to the technical field of hot runners, and in particular relates to a color-changing nozzle of a hot runner. The color-changing nozzle of the hot runner comprises a hot nozzle body, a nozzle core and a nozzle core sleeve, wherein an inner cavity is formed in the hot nozzle body; the nozzle core is arranged in the inner cavity; a nozzle tip of the nozzle core penetrates into the nozzle core sleeve; the nozzle core is provided with at least two partition plates which are annularly distributed along the nozzle tip; the nozzle core is matched with the nozzle core sleeve to form at least two plastic melting runners; a connection part is arranged at one end of the nozzle core sleeve and is sleeved with a sealing cover. By improving the structure of the nozzle tip of the nozzle core, a dead angle effect is not generated when molten plastic passes through the nozzle tip, the molten plastic can completely flow into a mold cavity, and the problem of product quality caused by blocking of the nozzle tip is solved.

Summary of the invention
The purpose of this utility model is to provide a kind of hot flow path colour changing nozzle for the deficiencies in the prior art, the utility model is by improveing the structure of chewing point of chewing core, do not produce dead angle effect when making the melt plastic cement process chew point, can flow into fully in die cavity, avoid occurring producing product quality problem because chewing the point obstruction.
For achieving the above object, a kind of hot flow path colour changing nozzle of the present utility model, comprise that heat chews body and chew core, described heat is chewed body and is provided with inner chamber, the described core of chewing is arranged in inner chamber, described nozzle also comprises chews core retainer plate, the described point of chewing of chewing core is arranged in and chews core retainer plate, the described core of chewing is provided with minimum two demarcation strips, described demarcation strip is along chewing sharp annular array, describedly chew core and chew core retainer plate and coordinate and form minimum two melt adhesive runners, described core retainer plate one end of chewing is provided with connecting portion, and described connecting portion is socketed with seal cover.
As preferably, described seal cover and the connecting portion interference fit of chewing core retainer plate.
As preferably, the described core retainer plate of chewing is socketed with sprue bush.
As preferably, the described core of chewing is provided with two demarcation strips.
As preferably, the described core of chewing is provided with three demarcation strips.
As preferably, the described core of chewing is provided with four demarcation strips.
The beneficial effects of the utility model: chew core and be provided with minimum two demarcation strips, chewing the core insertion chews in core retainer plate, the spatial separation that demarcation strip will be chewed in core retainer plate becomes several melt adhesive runners, melt plastic cement enters in die cavity by melt adhesive runner, chew the seal cover of core retainer plate socket and chew core retainer plate and hot gap of chewing between body for sealing, prevent that melt plastic cement from entering the gap, seal the place, dead angle; The utility model does not produce dead angle effect by the structure of chewing point of chewing core is improved when making the melt plastic cement process chew point, can flow into fully in die cavity, avoids occurring producing product quality problem because chewing the point obstruction.
