Abstract

The invention discloses a hot runner nozzle with an auxiliary injection function. The hot runner nozzle comprises a runner column body and a spraying head, wherein the spraying head is fixed on the inner wall of a liquid storage cavity; the liquid storage cavity is internally provided with an auxiliary injection system; the auxiliary injection system comprises an auxiliary air spraying head, a threaded joint, an elastic block, a sleeve head, an air pipe and a valve; the auxiliary air spraying head is movable and abuts against or is separated from a liquid storage channel; and the elastic block is arranged between the auxiliary air spraying head and the threaded joint. The hot runner nozzle has the beneficial effects that (1) the valve of the auxiliary injection system is closed in an injection process and melted liquid is injected into a mold; after a certain quantity of the melted liquid is injected, the valve is opened; the auxiliary air spraying head moves frontwards to block the liquid storage channel under the effect of air pressure, so that the connection between a workpiece and the melted liquid is cut off, and air induction and pressure keeping are carried out on the workpiece in the mold; after the workpiece is cooled, the valve is closed; and the auxiliary air spraying head rebounds backwards under the action of the elastic block and is separated from the liquid storage channel, and a flowing channel of plastic melted liquid is smooth.

Description

A kind of hot-runner nozzle with auxiliary injection function
Technical field
The present invention relates to a kind of hot-runner nozzle, specifically a kind of hot-runner nozzle with auxiliary injection function.
Background technology
Hot nozzle is the important component part of TOP-TIP, is commonly used in Injection Industry, and the periphery of hot nozzle is provided with heating system, makes the plastics liquation in cavity be in molten state always, so that can fluid fast when next time injects, saves time.
Sometimes in order to obtain the cavity of storage or liquid, or in order to saving in weight and material, making a cavity within the workpiece, generally will complete auxiliary injection with water or gas in this case, make workpiece produce a cavity.
Existing auxiliary injection is after injection completes, plastics liquation for the formation of workpiece is connected with the plastics liquation remained in runner cylinder, after the liquation cooled and solidified of injection port can only be waited until, workpiece could be separated and remain in the plastics liquation in runner cylinder, consuming time so few, the overlap of workpiece is many, and column cap is long.
Summary of the invention
The present invention is directed to prior art deficiency, when pressurize is provided, a kind of hot-runner nozzle with auxiliary injection function of the association between the plastics liquation forming workpiece and the plastics liquation remaining in runner cylinder can be blocked.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: a kind of hot-runner nozzle with auxiliary injection function, comprise runner cylinder and shower nozzle, liquid passage and liquid storage chamber is set in described runner cylinder, liquid storage passage and injection port are set in described shower nozzle, described shower nozzle is fixed on the inwall in described liquid storage chamber, auxiliary injection system is provided with in described liquid storage chamber, described auxiliary injection system comprises auxiliary jet thrust, nipple, elastomer block, pullover, tracheae and valve, described nipple, described pullover and described tracheae maintains static, described auxiliary jet thrust is movable, against or depart from described in liquid storage passage, described elastomer block is arranged between described auxiliary jet thrust and described nipple.
Described liquid storage channel setting has the first chamfering, and described auxiliary jet thrust is provided with the second chamfering, the first described chamfering can against or depart from described in the second chamfering.
The front end of described nipple convexes to form a processing step to the inside, the tail end of described auxiliary jet thrust is provided with a cannelure, the width of described cannelure is greater than the thickness of described processing step, and described elastomer block is buckled on the trailing flank of described processing step and described cannelure.
The present invention compared with prior art, has following beneficial effect: 1) when injecting, the valve closing of accessory system, and plastics liquation injects mould; After a certain amount of plastics liquation of injection, valve opening, under the influence of air pressure, auxiliary jet thrust forward activity blocks liquid storage passage, blocks contacting of workpiece and plastics liquation, and carries out aerating and pressurize to the work in mould; After work-piece cools, valve closing, auxiliary jet thrust is under the effect of elastomer block, and resilience backward, departs from liquid storage passage, make the flow channel of plastics liquation unimpeded; 2) be provided with the first chamfering and the second chamfering, play guide effect.
Accompanying drawing explanation
Fig. 1 be the embodiment of the present invention penetrate note time working state figure.
Working state figure when Fig. 2 is the pressurize of the embodiment of the present invention.
Detailed description of the invention
Be described in further detail the present invention below in conjunction with accompanying drawing and detailed description of the invention: shown in Fig. 1 ~ 2, in figure, mark is as follows: runner cylinder 1, enter liquid passage 11, liquid storage chamber 12, shower nozzle 2, liquid storage passage 21, injection port 22, first chamfering 23, auxiliary injection system 3, assist jet thrust 31, nipple 32, elastomer block 33, pullover 34, tracheae 35, valve 36, second chamfering 37, processing step 321, cannelure 311.
A kind of hot-runner nozzle with auxiliary injection function comprises runner cylinder 1 and shower nozzle 2, liquid passage 11 and liquid storage chamber 12 is set in runner cylinder 1, liquid storage passage 21 and injection port 22 are set in shower nozzle 2, shower nozzle 2 is fixed on the inwall in liquid storage chamber 12, and plastics liquation injects mould from entering liquid passage 11, liquid storage chamber 12, liquid storage passage 21 and injection port 22 successively.
Now, in liquid storage chamber, 12 are provided with auxiliary injection system 3, can be used for inflating or liquid, auxiliary injection system 3 comprises auxiliary jet thrust 31, nipple 32, elastomer block 33, pullover 34, tracheae 35 and valve 36, nipple 32, pullover 34 and tracheae 35 maintain static, auxiliary jet thrust 31 is movable, against or depart from liquid storage passage 21, elastomer block 33 is arranged between auxiliary jet thrust 31 and nipple 32.
