State be additionally provided in Rotational Cylindrical 601 for drive Rotational Cylindrical 601 move Power Component 605, set injection molding discharge port 5 with
Injection molding feed inlet 4 be in same linear position, and set high-pressure jet head 602 then divide be molded discharge port 5 and be molded into
Material mouth 4 is at an angle of 90 degrees, in this way in rotary motion column 601, then can control high-pressure jet by the L shape connecting hole 603 of setting
Connection relationship between first 602 and injection molding discharge port 5 and injection molding feed inlet 4 connects in high-pressure jet head 602 and injection molding discharge port 5
When logical, start extraneous air pump by 602 ejections high pressure draughts of high-pressure jet, so as to make a part of heels from being molded by
Material mouth 5 is discharged, and when high-pressure jet head 602 is connected to injection molding feed inlet 4, then it is achievable will be remaining another in injecting head 3
Partially material enters and leaves to barrel 1, then carrying out heating thawing by barrel 1 is discharged it from discharge gate 8, can effectively avoid being molded
First 1 the problem of blocking, cleared up enhanced convenience.
You need to add is that the corner of L shape connecting hole 603 is arcuate structure, connected to reduce high pressure draught by L shape
Connect loss when hole 603.
It further supplements, high-pressure jet head 602, injection molding discharge port 5 and injection molding feed inlet 4 are close to Rotational Cylindrical 601
One end may be provided with metallic packing ring, and metallic packing ring can resist rotation by minitype motor driving, and then in connection
Column 601 realizes the sealed connection between its three, can avoid the problem of will appear material leakage in discharge or injection molding, metal sealing
Ring can be used 718 alloys and be made, it is ensured that it can ensure the leakproofness of its connection with enough heat-resisting quantities.
The Power Component 605 includes the rotation axis 606 being arranged in Rotational Cylindrical 601, is arranged in the rotation axis 606
The turning set 607 driven by driving motor, the inside of the turning set 607 are provided with sliding groove 610, and in the rotation axis
Fixed block 611 corresponding with sliding groove 610 is provided on 606, the turning set 607 passes through sliding groove 610 and fixed block 611
Chimeric to be slidably connected with rotation axis 606, i.e., set turning set 607 can be rotated same under the drive of driving motor
When, the sliding of front and back can also be carried out, is provided with encoder, encoder on the driving motor in addition turning set 607 being driven to move
Be signal or data are worked out, being converted to can be used to communicates, the equipment of the signal form of transimission and storage, can be angular displacement
Or straight-line displacement is converted into electric signal, can play the purpose being precisely controlled to 601 rotational angle of Rotational Cylindrical in the present embodiment,
It avoids it from hole location occur not right, leads to the problem of will appear spillage in injection molding or discharge.
It is additionally provided with rotation sliding slot 608 in the rotation axis 606, is fixedly installed on the injection molding machine and rotation sliding slot
The fixation limited block 609 of 608 chimeric connections, the rotation sliding slot 608 includes smooth section 612 and tilting section 613, described smooth
Section 612 is at least provided with 606 perimeter of a quarter rotation axis, i.e., set smooth section 612 is at least available in Rotational Cylindrical 601 and exists
Same position carries out 90 degree of rotation, to guarantee that it can be changed high-pressure jet head 602 and be molded by by L shape connecting hole 603
Connection relationship between material mouth 5 and injection molding feed inlet 4 is continued to rotate when turning to tilting section 613, can make Rotational Cylindrical
601 move forward, i.e., after movement to a certain extent, the connection through-hole 604 for being placed in rear can be made to be in injection molding feed inlet 4 and note
Mould between discharge port 5, thus the connection realizing injection molding feed inlet 4 and being molded between discharge port 5, further reach normal injection molding with
And to the purpose that injecting head 3 is cleared up.
The second embodiment of its first cleaning assembly can are as follows: high-pressure jet head 602, injection molding feed inlet 4 and injection molding discharging
It is angularly to be arranged between mouth 5, the setting of Rotational Cylindrical 601 is in high-pressure jet head 602, injection molding feed inlet 4 and injection molding discharge port 5
Center, open up the V-arrangement through-hole of 60 degree of angle in Rotational Cylindrical 601, and then drive rotation passing through driving motor
When column 601 moves, every 60 degree of rotation by switching high-pressure jet head 602, injection molding feed inlet 4 and can be then molded by by V-arrangement
A connection status between 5 three of material mouth realizes above-mentioned same purpose.
You need to add is that being provided with resistive heater around Rotational Cylindrical 601, led to avoid injection molding material in V-arrangement
In hole the problem of cooling blocking.
First embodiment compared with second embodiment, injection molding when be more less prone to putty the problem of, discharge
With the cleaning for injecting head can enhanced convenience, and second embodiment, compared with first embodiment, structure is more
It is simple, the cost used can be effectively reduced.
Second cleaning assembly 7 includes that barrel 1 is arranged in far from 3 one end of injecting head and by the peace of electric pushrod driving
Loading board 701 offers the first guide chute 702 on the mounting plate 701, and the mounting plate 701 passes through the first guide chute
702 slidably connect cleaning block 703 corresponding with rotation screw rod 2, are provided with and the first guide chute in the inner wall of the barrel 1
702 corresponding second guide chutes 704, the first guide groove 702 and the second guide groove 704 constitute a complete guide groove,
It is limited for the sliding scale to cleaning block 703, can avoid its movement beyond distance to a declared goal, and cause to clear up 703 nothing of block
Method returns to the problem on mounting plate 701.
Set mounting plate 701 is the position to maintain an equal level with barrel 1, Jin Er by the maximum distance that electric pushrod moves
When maintaining an equal level with barrel 1, the first guide chute 702 then can be in same position with the second guide chute 704, so as to make to be placed in
Cleaning block 703 on mounting plate 701 is moveable in barrel 1, realizes the rotation by rotating screw rod 2 to drive cleaning block 703
Movement, and then its movement when can realize to rotation screw rod 2 cleaning, can effectively avoid rotation screw rod 2 on remaining have greatly
The clout of amount can not expect to clean by PP, and the clout when injecting virgin material is caused to mix with virgin material, and the product of injection molding is made the flaw occur
The problem of defect.
In addition, cleaning 703 thickness of block is equal to the spacing on rotation screw rod 2 between adjacent two spiral shells leaf, described second is clear
Component 7 is managed at least provided with two, realizes cleaning synchronous up and down, guarantees the cleaning effect to rotation screw rod, i.e. cleaning block 703
It is stuck on rotation screw rod 2, realizes when rotating the movement of screw rod 2, its spiral shell leaf and the body of rod can be carried out by cleaning block 703 thorough
Cleaning, to avoid on rotation screw rod 2 the problem of remaining a large amount of clout.
When electric pushrod drives cleaning block 703 to be caught in rotation screw rod 2, rotation screw rod 2 is also moved with electronic
The movement of push rod and move, i.e. the motion amplitude of rotation screw rod 2 and the motion amplitude of electric pushrod matches, avoidable to block
Dead problem.
Although above having used general explanation and specific embodiment, the present invention is described in detail, at this
On the basis of invention, it can be made some modifications or improvements, this will be apparent to those skilled in the art.Therefore,
These modifications or improvements without departing from theon the basis of the spirit of the present invention are fallen within the scope of the claimed invention.
