Description
Technical field
Extruder head backstop described in the utility model, is related to a kind of backstop of injection-moulding device.
Background technology
By two end faces for the check ring of plane is constituted, it there are many extruder head backstop of existing injection-moulding device
Defect, such as：1st, because end face material stock is serious, cause non-return effect poor；2nd, because without location structure, causing material grain direction to hinder
The problems such as power is big.
For it is above-mentioned the problems of in the prior art, a kind of new extruder head backstop of research and design so that
Overcome is the problems of in the prior art very necessary.
The content of the invention
In view of it is above-mentioned the problems of in the prior art, the purpose of this utility model is that research and design is a kind of new squeezes
Lift one's head backstop.It is used to solve present in prior art：1st, because end face material stock is serious, cause non-return effect poor；2nd, because
It is without location structure, the problems such as cause material grain direction resistance big.
What technical solution of the present utility model was realized in：
Extruder head backstop described in the utility model, it is characterised in that described backstop includes connection ring, stops
Inverse ring, barrel and pushing screw rod；Connection ring fixes the middle part loaded on barrel, and one end of connection ring is equipped with guide, and the other end sets
It is equipped with check ring；Front end of the check ring loaded on pushing screw rod.
Connection ring described in the utility model is cyclic structure；Connection boss is machined with the front end surface of connection ring, even
Connect ring and be connected with the recessed groove at forward guide rear portion by connecting boss, gap is left in junction；The rear end of connection ring adds
The inner conical surface of the oriented inner side of work.
Check ring described in the utility model is cyclic structure；It is machined with the outer wall of check ring front portion and inner conical surface cooperation
Outer frustum.
Connection boss described in the utility model is uniform along end face, and connection boss includes boss long and short boss, and length is convex
Platform and short boss interval setting.
In feeding forward, connection ring is separated the utility model with check ring, and material is left between inner conical surface and outer frustum
Passage；Pushing screw rod rotates under the drive of motor and pushes material forward, leads to by the material between inner conical surface and outer frustum
Extruded by extruder head forward through guide in road；When needing to stop feeding, screw rod is pushed forward, on screw front end check ring
Inner conical surface closure in outer frustum and connection ring, material channel is closed, and material cannot pass through, the anterior material of connection ring also without
Method inversely returns expects pipe rear portion.
The utility model has the advantages that it will be apparent that being mainly manifested in：
The utility model has structure novelty, simple processing, easy to use, non-return effect are good, material grain direction is good etc.
Advantage, it in high volume puts goods on the market will produce positive social benefit and significant economic benefit.
Brief description of the drawings
The utility model has 4 width accompanying drawings, wherein：
Accompanying drawing 1 is the utility model connector and check ring exploded perspective schematic diagram；
Accompanying drawing 2 is the utility model connector and check ring closure state structural representation；
Accompanying drawing 3 is connection ring structure schematic diagram；
Accompanying drawing 4 is check ring structural representation.
In figure：1st, the guide of barrel 2,3, connection ring 31, connection boss 32, inner conical surface 4, check ring 41, outer cone
Platform 5, pushing screw rod.
Specific embodiment
Specific embodiment of the utility model as shown in drawings, backstop include connection ring 3, check ring 4, barrel 1 and
Pushing screw rod 5；Connection ring 3 fixes the middle part loaded on barrel 1, and one end of connection ring 3 is equipped with guide 2, and the other end is provided with only
Inverse ring 4；Front end of the check ring 4 loaded on pushing screw rod 5.
Connection ring 3 is cyclic structure；Connection boss 31 is machined with the front end surface of connection ring 3, connection ring 3 is by connection
Boss 31 is connected with the recessed groove at the rear portion of forward guide 2, and gap is left in junction；The rear end of connection ring 3 is machined with inwardly
The inner conical surface 32 of side.
Check ring 4 is cyclic structure；The outer frustum 41 coordinated with inner conical surface 32 is machined with the anterior outer wall of check ring 4.
Connection boss 31 is uniform along end face, and connection boss 31 includes boss long and short boss, between boss long and short boss
Every setting.
The above, preferably specific embodiment only of the present utility model, but protection domain of the present utility model is simultaneously
Be not limited to this, all those familiar with the art in technical scope disclosed in the utility model, according to this reality
Being subject to equivalent or change with new technical scheme and its design of the present utility model all should cover of the present utility model
Within protection domain.
