To being fitted on filling barrel 16 for ring 45, triggering shell 10 by the cooperation of guide ring 45 and annular guide channel 35 can be along showwing loving care for
The rotation of 16 axis of barrel but not sliding.
As shown in Figure 10,12, one end of reset spring 29 is mounted on sliding disc 9, and the other end of reset spring 29 is logical
The mode for crossing welding is mounted on 8 outer ring of one-way clutch；The effect of reset spring 29 is to play reset to sliding disc 9 to make
With, while making the outer ring of one-way clutch that connection ring be driven to be restored on original position in rotation direction.
Above-mentioned reset spring 29 is compressed spring.
As shown in figure 19, circumferential on the periphery of above-mentioned drive ring 28 to be equably provided with multiple mounting grooves 49, multiple triggerings
Block 31 respectively by being fitted on drive ring 28 with the mounting groove 49 opened on drive ring 28, each triggering block 31 with it is right
A triggering driving spring 30 is mounted in the mounting groove 49 answered；When sliding disc 9 drives the rotation of 8 outer ring of one-way clutch
When, one-way clutch 8 will drive the rotation of rotation spring 51, and rotation spring 51 can give triggering 10 1 rotary forces of shell, trigger shell 10
Driving shifting block 48 mounted thereto be will drive under this rotary force around triggering 10 axis of shell rotation, when driving shifting block 48 and driven
After corresponding triggering block 31 contacts on rotating ring 28, triggering block 31 will be under the action of driving shifting block 48 to stir on drive ring 28
49 medial movement of corresponding mounting groove opened, triggering block 31 can give driving 48 1 reaction forces of shifting block, so that triggering shell 10
It is opposing stationary, power on rotation spring 51, when most endpoint of the driving shifting block 48 close to 31 side of triggering block is moved to triggering block 31
Behind most sharp place, sliding disc 9 stops driving triggering shell 10, and triggering block 31 loses the limit to driving shifting block 48 at this time, at this
Under kind state, trigger ring just will drive driving 48 quick rotation of shifting block under the action of rotation spring 51, so that driving shifting block 48
A triggering block 31 being moved to positioned at rear side contacts.
Above-mentioned triggering driving spring 30 is compressed spring.
Above-mentioned drive ring 28 is mounted on by welding on filling barrel 16.
Specific workflow drives 12 turns of screw rod by driving unit 3 when the injection mold designed using the present invention
It moves, is rotated by screw rod 12 and driving screw thread 47 is driven to be added to the offer driving of the plastics in filling barrel 16 to by charging hopper 2
Power so that plastics in filling barrel 16 be moved to after the heating of heater 6 in rotation shell 7 one end for being provided with injection port 24 with
In gap between sliding disc 9, and the plastics for being moved to this section run past rotation shell 7 on injection port 24 and in injection port
The discharge port 18 opened on the mounting shell 14 of 24 connections is flowed into corresponding mold cavity；After the mold cavity is injected completely, turn
The amount of plastic being provided between one end of injection port 24 and sliding disc 9 in dynamic shell 7 will be continuously increased, and the pressure of plastics constantly increases
Add, the plastics of this section will squeeze the sliding of sliding disc 9, and sliding disc 9 can be squeezed by helical teeth 42 mounted thereto and be installed
Triggering drive block 33 on 8 outer ring of one-way clutch, when so that 8 outer ring of one-way clutch rotating, one-way clutch 8 can band
Dynamic rotation spring 51 rotates, and rotation spring 51 can give triggering 10 1 rotary forces of shell, and triggering shell 10 will drive under this rotary force
Driving shifting block 48 mounted thereto is around triggering 10 axis of shell rotation, when driving shifting block 48 and corresponding triggering on drive ring 28
After block 31 contacts, triggering block 31 will under the action of driving shifting block 48 to stir the corresponding mounting groove that be opened on drive ring 28
49 medial movements, triggering block 31 can give driving 48 1 reaction forces of shifting block, so that triggering shell 10 is opposing stationary, rotation spring 51
Upper power, after driving most endpoint of the shifting block 48 close to 31 side of triggering block to be moved to the most sharp place of triggering block 31, sliding disc 9 stops
Only driving triggering shell 10, triggering block 31 loses the limit to driving shifting block 48 at this time, and in this state, triggering ring is rotating
It just will drive driving 48 quick rotation of shifting block under the action of spring 51, so that on the injection port 24 and mounting shell 14 on rotation shell 7
Another in two discharge ports 18 opened is connected；For the corresponding mold intracavitary administration of discharge port 18；It ensure that injection
Continuity, while making a triggering block 31 contact for driving shifting block 48 to be moved to positioned at rear side.
