It is fixed on cavity, the arc-shaped transition face that can be contacted with ball is arranged in the other end, and connection cavity and nozzle are equipped among cushion block
Through-hole；Spring one end is fixed on the outer pars intramuralis close to top end opening, and ball is arranged between the other end and cushion block.
Preferably, the end set guide groove of pipeline.
Preferably, cold runner is set between pipeline and injection apparatus, and cold runner uses water-cooling structure.
Preferably, thermal insulation layer is set between cold runner and pipeline, and thermal insulation layer is asbestos or glass fibre.
The utility model has following advantageous effect：By structure simple as possible, keeps partial function integrated, operated simplifying
Sequence and repair difficulty, in addition make liquid-state silicon gel not outside solidification make environment dirty.

Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
As Figure 1-Figure 2, the utility model proposes a kind of nozzle of silica gel mould, including pipeline 4, outside pipeline 4
It is connected with the feed inlet 10 of hydraulic cylinder 3 and liquid-state silicon gel, slidable injection apparatus is set in pipeline 4, injection apparatus includes
The feed inlet 10 of cavity 2 and nozzle 1, cavity 2 and liquid-state silicon gel is connected to, and 2 one end of cavity connects hydraulic cylinder 3, other end connection
Nozzle 1；By injecting liquid-state silicon gel into feed inlet 10, liquid-state silicon gel can be sprayed in nozzle 1, by hydraulic cylinder 3, be realized
The sliding back and forth in pipeline 4 of nozzle 1.
For 1 outside setting of nozzle there are the cone shaped outer wall of top end opening 14, inside includes spring 13, ball 11 and cushion block
12,12 one end of cushion block is fixed in nozzle 1, the arc-shaped transition face 121 that other end setting can be contacted with ball 11, in cushion block 12
Between be equipped with connection cavity 2 and nozzle 1 through-hole；13 one end of spring is fixed on the outer pars intramuralis close to top end opening 14, the other end
Ball 11 is set between cushion block 12, and ball 11 plays non-return effect so that the liquid-state silicon gel that feed inlet 2 injects can eject rolling
Pearl 11 sprays, and the silica gel having been injected into is attached to arc-shaped transition face 121 against ball 11, because without flowing back.
The end set guide groove 6 of pipeline 4, when needing injection molding, the silica gel mould inlet of moving nozzle to mold 5
It sets, by guide groove 6, nozzle is fixed in the position, and when nozzle 1 is resisted with silica gel mould inlet 5, guide groove 6 also can
Liquid-state silicon gel is run out of caused by preventing connection unstable.
Cold runner 7 is set between the tube wall 9 and injection apparatus of pipeline 4, and it is note that cold runner 7, which uses water-cooling structure, the structure,
Common structure in modeling, for preventing liquid-state silicon gel from just curing in nozzle, caused nozzle blockage.
Thermal insulation layer 8 is set between cold runner 7 and the tube wall 9 of pipeline 4, and the thermal insulation layer 8 is asbestos or glass fibre.
Motion mode：
Up and down molding after, hydraulic cylinder 3 act, until cone 1 outer wall of nozzle offset with silica gel mould inlet 5,
Liquid-state silicon gel is injected in feed inlet 10 at this time, and liquid-state silicon gel is injected into cavity 2, then ball 11 is pushed up by the through-hole of cushion block 12
It rises, while being flowed through from gap of the ball 11 with arc-shaped transition face 121, entered in mold across top end opening 14, completed
Injection process；
After the completion of injection, until liquid-state silicon gel fills up mold, at this time there is no the entrance of new liquid-state silicon gel, ball 11 by
The effect of 13 power of spring is pushed on arc-shaped transition face 121, and the liquid of mould inside can only press against ball 11 and more be adjacent to circle
Arc transiting surface 121 plays the role of non-return reflux；
Until the liquid-state silicon gel fixed line condensation in mold, removes the nozzle and complete injection moulding process.
A variety of modifications of embodiment will be apparent to those skilled in the art, determine herein
The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause
This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The widest range consistent with features of novelty.
