The embodiment of the invention also provides a kind of ceramic part injection moulding methods, specifically includes the following steps:
S1, filling stage: filling ceramic melt in the die cavity of Guan Bi mould, until mould cavity is filled to default
Amount；
S2, packing stage: to the ceramic melt continu to press of injection；
S3, cut into 102 stage of chewing-gum: control driving assembly 14 drives shovel 13 to move along the die sinking direction perpendicular to mold
It is pressed downward with band movable slider 151, and then blocks import glue 102 with movable slider cutter 152, ceramic part 100 and runner is isolated
101；
S4, cooling stage: ceramic melt is cooled and solidified to it with certain rigidity；
S5, ejection phase: ceramic part 100 and runner 101 are ejected into die cavity.
Specifically, in above-mentioned steps S1, filling is the first step during entire injection circulation, since mold closure
Injection is counted, until mould cavity is filled into about 98%.
In above-mentioned steps S2, the effect of packing stage is continu to press, is compacted melt, increases ceramic melt density
(density), to compensate the contraction of melt.
In above-mentioned steps S4, cooling stage, which is that ceramic melt is cooled, is cured to certain rigidity, is only cured to certain
Rigidity just can make ceramic part 100 by smooth ejection die.
In above-mentioned steps S5, ejection phase is that ceramic melt cooling and solidifying to product after certain rigidity is removed mold
It is the last one link in injection moulding circulation.
Specific work steps are as follows: when ceramic melt starts to be injected into mould cavity, complete step S1 and the S2 stage fill with
After pressure maintaining, before the step S4 stage is cooling, melt is not also also in connection status and at this time for glue-feeder and ceramic part 100
Solidification, to X sections of distances are pushed forward, (this distance needs basis to the control unit control cylinder 142 driving shovel 13 of injector connection at this time
Depending on 102 size of actual product and import glue), the thrust of shovel 13 blocks Y sections of distances of the pushing of sliding block 151 by glue-feeder, this
When product be automatically separated with runner 101, have reached and cut into the purpose of chewing-gum 102 automatically in mould inside.Import glue 102 separates
After continue the cooling of step S4 stage and solidify ceramic melt, step S5 stage injection machine mandril, which stretches out, drives lower ejector retainner plate
251 and upper ejector retainner plate 252, make that thimble 253 ejects ceramic part 100 and runner 101 completes demoulding；Last control unit control
Cylinder 142 drives 13 return of shovel, and slide block assembly 15 up resets under the driving of spring, while the ejecting mechanism of injector moves back
It returns, upper ejector retainner plate 252, lower ejector retainner plate 251 and thimble 253 are retracted reset by reset spring 254, and injector molding completes one
A production cycle.
In conclusion a kind of ceramic part injecting molding die provided in an embodiment of the present invention and its injection moulding method,
It is fixed on sliding block 151 and is moved downwardly together with sliding block 151 to block the sliding block cutter 152 of import glue 102 by setting,
So that ceramic part 100 is separated with runner 101, that is, realize and cut off import glue 102 automatically in mould inside, replaces manually cutting
Except import glue 102, so that accessory appearance consistency is more stable, meet client to product requirement, and without taking much time
It corrects remaining 102 trace of import glue on accessory appearance, achievees the purpose that improve production efficiency, reduces cost of labor.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modification, equivalent replacement or improvement etc., should all be included in the protection scope of the present invention within mind and principle.
