Disconnected location guide leads to position movement so that gap two turns on jet flow groove, and now, material is reached in guiding gutter by gap two, thing
Material by guiding gutter reach injection core front end, now, material constantly accumulation injection core front end, material promote injection core to
After move, when inject core be moved to setting value when, complete discharging metering；After completing storing, start the driving of the second actuator and penetrate
Core moves from the front to the back, and during being somebody's turn to do, injection core moves forward, and in other words, is moved rearwards equivalent to check ring, check ring is by leading
Logical position is mobile to blocking position so that gap one and jet flow groove blocking, check ring blocking and sealants enter passage, note
Core shooting promotes check ring to continue to move along, and promotes the plastic material of melting to move forward, plastic material is flowed into by injection port
The mold cavity of locking is molded and product is taken out after cooling down, and the product of injection molding is completed.
Further, when material reaches the gap two between locating part and injection tube, under the pressure effect of material, only
Inverse ring along penetrate point axially away from locating part so that gap one is connected with jet flow groove by gap two, now, material passes through gap
Two are reached in guiding gutter, and material reaches the front end for penetrating point by guiding gutter, and now, the front end of point, thing are being penetrated in material constantly accumulation
Material promotes injection core to be integrally moved rearwards, and when injection core is moved to setting value, completes discharging metering；After completing storing, open
Dynamic second actuator driving core shooting moves from the front to the back, and during being somebody's turn to do, injection core moves forward, in other words, equivalent to check ring
Be moved rearwards, check ring along penetrate point axially adjacent to locating part so that gap one is blocked with jet flow groove by gap two, check ring
Block and sealants enter passage, injection core promote check ring continue to move along, promote the plastic material of melting forward
Mobile, the mold cavity that plastic material is locked by injection port inflow is molded and takes out product, the product of injection molding after cooling down
Complete.
In the present embodiment, the path of injection core front end is entered by check ring sealants, prevents plastic material along originally
Revealed into passage, in material injection, the metering of material can be made more accurate, and prevent material leakage to equipment
Pollute.
Also, when plastic material is accumulated, material continues to build up from the front to the back along the axial direction of injection tube, injection core promotes material
During injection, the material for being introduced into injection tube first projects, and is projected after the rear material for entering injection tube, realizes first in first out, without dead
Angle, it is ensured that material is non-degradable in injection or decomposes and causes the bad phenomenons such as discoloration.
As the further improvement of above-mentioned technical proposal, injecting assembly 22 also includes being socketed in injection core 222 and injection tube
Seal 2227 between 221, arc material road 2228 is provided with seal 2227；The first end of arc material road 2228 and feeding
Component 12 connects, and the second end of arc material road 2228 connects with gap 1.The setting of arc material road, material can be made by splicing
Mouth is smoothly reached in gap one, and arc material road does not have knuckle or dead angle in itself, and material will not accumulate in arc material road, reduces thing
The waste of material, while improve the smoothness of material operation.
As the further improvement of above-mentioned technical proposal, the first end of arc material road is connected by material receiving port and feeding material component
Connecing, material receiving port, arc material road and gap one are sequentially communicated to form monoblock type arc road,
Material receiving port, arc material road and the gap one of injection tube are sequentially communicated as monoblock type arc road, can further make material
Smoothly reached in gap one by material receiving port, monoblock type arc road does not have knuckle or dead angle in itself, and material will not accumulate in arc road
It is tired, the waste of material is reduced, while further improve the smoothness of material operation.
The another object of the embodiment of the present invention, which also resides in, provides a kind of former, the former include mould and
As above injection machine, the injecting assembly of injection machine and the die cavity of mould connect.
Above-mentioned former is same as above-mentioned injection machine having compared to prior art compared to the beneficial effect of prior art
Beneficial effect, here is omitted.
Finally it should be noted that：Various embodiments above is merely illustrative of the technical solution of the present invention, rather than its limitations；To the greatest extent
