Embodiment
For feature of the present utility model, technological means and the specific purposes reached, function can be further appreciated that, below
The utility model is described in further detail with embodiment with reference to accompanying drawing.
Referring to figs. 1 to Fig. 5.
The utility model embodiment discloses a kind of automatic blockage structure of more die cavitys, including board 10, and board 10 is provided with recessed
Sunken sprue 11, it is connected provided with least two runners 12, one end of runner 12 with sprue 11 around sprue 11,
Die cavity 13 is led in the connection of the other end of runner 12, and runner 12 is provided with corresponding blockage mechanism 20；Blockage mechanism 20 includes recessed
Sunken blocking groove 21, plugging block 22 and cylinder 25, blocks groove 21 and corresponding runner 12 is arranged in a crossed manner, that is, blocks groove 21 and block
Runner 12, blocking and mobilizable plugging block 22 is inlaid with groove 21, plugging block 22 includes circulation and blocks section 23 and linkage section 24,
The one end of linkage section 24 blocks section 23 with circulation and is fixedly connected, and the other end of linkage section 24 is fixedly connected with the output end of cylinder 25, gas
Cylinder 25 can adjust the position for blocking circulation section 23 by linkage section 24；Circulation blocks the top of section 23 and is provided with circulation notch 231, stream
A diameter of d of groove mouth 231, it is a that circulation notch 231 to circulation, which blocks one end distance away from cylinder 25 in section 23, runner
One end distance of 12 to remote cylinder 25 on blocking groove 21 is b, b>A and d<B-a, circulation is blocked section 23 and blocking groove
Activity in 21, and when the notch 231 that circulates misplaces with runner 12, circulation blocks section 23 can be completely plugged corresponding point
Runner 12.
As shown in Fig. 2 under normal circumstances, the circulation notch 231 that circulation is blocked in section 23 is directed at corresponding runner 12, melt
Runner 12 can be reached from sprue 11 by melting plastics, then enter corresponding die cavity 13 from runner 12；As shown in figure 3, only
When needing certain 13 model of die cavity, worker clicks on circuit controling switch, and the cylinder 25 of the corresponding model of die cavity 13 will promote plugging block
22 travel forward, and circulation notch 231 is misplaced with the runner 12, and then the blocking section 23 that circulates blocks the runner 12
Block, molten plastic can not enter corresponding die cavity 13 from the runner 12, so as to obtain the injection molding effect of selectivity.This
Utility model automaticity is high, and operation letter is answered conveniently, and security performance is high, and production efficiency is high.
To improve the smooth degree that circulation is connected with blocking action, based on above-described embodiment, groove 21 and runner 12 are blocked
Vertically, a diameter of D, the D=d of runner 12, when circulation or blocking, circulation blocks section 23 and can more completely realized pair
The circulation or blocking of runner 12.
