Description
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 of TOP-TIP, is commonly used in Injection Industry, and the periphery of hot nozzle, which is provided with, to be added
Hot systems so that the plastics liquation in cavity is constantly in molten state, can quickly to go out liquid in injection next time, are saved
Time.
Sometimes for the cavity for obtaining storage or liquid, or in order to save weight and material, one is made within the workpiece
Cavity, typically will complete auxiliary injection with water or gas in this case, workpiece is produced a cavity.
Existing auxiliary injection is after the completion of injection, for forming the plastics liquation of workpiece and remaining in runner cylinder
Plastics liquation is connected to, can only be when that after the liquation cooled and solidified of injection port, could separate workpiece and remain in runner cylinder
Interior plastics liquation, so takes less, the overlap of workpiece is more, and column cap is long.
The content of the invention
The present invention is in view of the shortcomings of the prior art, when providing pressurize, can block to form the plastics liquation of workpiece and remain in
A kind of hot-runner nozzle with auxiliary injection function of the association between plastics liquation in runner cylinder.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals：A kind of band auxiliary injection work(
Liquid passage and liquid storage chamber are set into the hot-runner nozzle of energy, including runner cylinder and shower nozzle, described runner cylinder, it is described
Liquid storage passage and injection port are set in shower nozzle, and described shower nozzle is fixed on the inwall of the liquid storage chamber, described liquid storage intracavitary
Auxiliary injection system is provided with, described auxiliary injection system includes auxiliary jet thrust, nipple, elastomer block, pullover, tracheae
And valve, described nipple, described pullover and described tracheae be fixed, and described auxiliary jet thrust is movable,
Against or depart from described liquid storage passage, described elastomer block be arranged on described auxiliary jet thrust and described nipple it
Between.
Described liquid storage passage is provided with the first chamfering, and described auxiliary jet thrust is provided with the second chamfering, described
One chamfering can against or depart from the second described chamfering.
The front end of described nipple convexes to form a processing step, the described tail end for aiding in jet thrust to inner side
An annular groove is provided with, the width of described annular groove is more than the thickness of described processing step, and described elastomer block is buckled in
Described processing step with the trailing flank of described annular groove.
The present invention compared with prior art, has the advantages that：1）In injection, the valve of accessory system is closed,
In plastics liquation injection mould；After a certain amount of plastics liquation of injection, valve opening under the influence of air pressure, aids in jet
Liquid storage passage is blocked in activity to head forward, blocks contacting for workpiece and plastics liquation, and to the work progress aerating in mould and guarantor
Pressure；After workpiece cooling, valve is closed, and auxiliary jet thrust is in the presence of elastomer block, and resilience backward departs from liquid storage passage so that
The flow channel of plastics liquation is unimpeded；2）The first chamfering and the second chamfering are provided with, guide effect is played.
Brief description of the drawings
Fig. 1 for the embodiment of the present invention working state figure when penetrating note.
Working state figure when Fig. 2 is the pressurize of the embodiment of the present invention.
Embodiment
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings：Referring to 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, the first chamfering 23,
Auxiliary injection system 3, auxiliary jet thrust 31, nipple 32, elastomer block 33, pullover 34, tracheae 35, valve 36, the second chamfering
37th, processing step 321, annular groove 311.
A kind of hot-runner nozzle with auxiliary injection function includes being set into runner cylinder 1 and shower nozzle 2, runner cylinder 1
Liquid storage passage 21 and injection port 22 are set in liquid passage 11 and liquid storage chamber 12, shower nozzle 2, and shower nozzle 2 is fixed on the inwall of liquid storage chamber 12
On, plastics liquation is successively from liquid passage 11, liquid storage chamber 12, liquid storage passage 21 and the injection mould of injection port 22 is entered.
Now, auxiliary injection system 3 is provided with liquid storage intracavitary 12, can be wrapped for inflation or liquid, auxiliary injection system 3
Include auxiliary jet thrust 31, nipple 32, elastomer block 33, pullover 34, tracheae 35 and valve 36, nipple 32, the and of pullover 34
Tracheae 35 is fixed, and auxiliary jet thrust 31 is movable, against or depart from liquid storage passage 21, elastomer block 33 is arranged on auxiliary jet
Between first 31 and nipple 32.
In injection, the valve of accessory system is closed, in liquation injection mould；After a certain amount of liquation of completion, valve
Open, under the influence of air pressure, liquid storage passage is blocked in activity to auxiliary jet thrust forward, blocks contacting for work and liquation, and right
Work in mould carries out aerating and pressurize；
Liquid storage passage 21 is provided with the first chamfering 23, and auxiliary jet thrust 31 is provided with the second chamfering 37, and the first chamfering 23 can
