Description
Technical field
This utility model relates to a kind of injection molding machine nozzle, is specifically related to the self-locking spray nozzle that a kind of cyclic process closes automatically.
Background technology
Self-locking spray nozzle is mainly used in preventing melt sialorrhea and wire drawing, is sometimes also used for seat and moves back (nozzle rollback) and feed afterwards.Have
Two kinds of main Types, common one is independent control, and more rare one is that cyclic process closes automatically.
There is following shortcoming in existing self-locking spray nozzle:
The independent self-locking spray nozzle controlled, is to utilize thimble structure (can be thimble, pin, steel ball etc.) valve nozzles.?
Common spring self-lock nozzle, pushes down thimble by compression spring and realizes the closing of nozzle.Injection pressure must sufficiently high ability
Overcome the active force of spring, thus open nozzle.The corresponding pressure loss means to produce to be sheared further and therefore makes to mould
Material heating further, causes the chemical changes such as degraded, and this is worst situation.If it is desired to avoid shearing effect, then will
Fully utilized external force drives thimble, and this is accomplished by a set of relative complex frame for movement.Although having derived a lot in industry
The independent mechanism driving thimble, but all involve great expense and service life is limited.
The self-locking spray nozzle that cyclic process closes automatically, is a slipper seal mechanism, relatively simple for structure.When board seat enters
Open time (the top die gate casing of nozzle).Otherwise, after board seat moves back (nozzle rollback), when board performs charging action,
Close under the effect of melt pressure in machine barrel.
In actual production process, the self-locking spray nozzle that cyclic process closes automatically seldom sees actual application.Reason is
During charging, in machine barrel, the foundation of melt pressure needs a bit of time, and nozzle closes response not soon, and anti-sialorrhea effect is limited.Portion
When dividing the particularly preferred raw material of mobility, feeding quantity the least, after even charging process terminates, nozzle completely closes not yet, always
At sialorrhea.
Utility model content
This utility model aims to provide the self-locking spray nozzle that a kind of cyclic process closes automatically, and it is intended to improve cyclic process certainly
The nozzle of the self-locking spray nozzle of dynamic Guan Bi closes response speed, and then improves anti-sialorrhea effect, improves its practicality and wide usage.
In order to solve the problems referred to above, the self-locking spray nozzle that the cyclic process that this utility model provides closes automatically have employed as follows
Technical scheme:
The self-locking spray nozzle that a kind of cyclic process closes automatically, it is characterised in that: comprise material mouth, compression spring, material mouth seat, mistake
Glue shuttle, described material mouth is connected by compression spring and material mouth seat, described cross glue shuttle through after material mouth seat and compression spring and
Material mouth is threadably secured.
Preferably, the described afterbody crossing glue shuttle is provided with flat recess, and the described front end crossing glue shuttle is provided with screw thread.
Preferably, the described rear end crossing glue shuttle is provided with glue-feeder.
Preferably, the inner side of described material mouth is provided with screw thread.
Preferably, the screw thread of described material mouth is provided with high temperature anti-sticking oxidant layer.
Preferably, the described screw thread crossing glue shuttle is provided with high temperature anti-sticking oxidant layer.
Preferably, it is provided with screw thread outside the rear end of described material mouth seat.
The beneficial effects of the utility model are: provide a kind of simple in construction, low cost, suitability self-locking widely spray
Mouth, and the nozzle of this kind of self-locking spray nozzle closes fast response time, can be effectively improved the sialorrhea effect after spray, improves in fact
With property and wide usage, and convenient maintenance and replacement.
