Fig. 2 is the side view of the utility model embodiment.
Fig. 3 is the main body of the utility model embodiment and the enlarged drawing of axle sleeve thimble sealing position.
Specific embodiment
The utility model is further described below in conjunction with figure embodiment.
As shown in Figure 1, 2, the pin type shut-off nozzles of injection molding machine, including adapter head 1, nozzle head 2, thimble 3, main body 4, axis
Cover 5, positioning screw 6, lever shaft 7, lever 8, cylinder 12.
4 front of aforementioned body is connect with adapter head 1 by forward flange 41, and 4 rear portion of main body is connected with adapter head 1 by rear flange 42
It connects, forward flange 41, main body 4, rear flange 42 are fixed by screw 9, and adapter head 1, main body 4, nozzle head 2 are respectively set interconnected
Runner, so that injection raw material passes through from runner, adapter head inner flow passage be located at avoids the position that lever 8 is taken up space.
The cavity 43 being connected to lower part is set among aforementioned body 4, and lever 8 is arranged in the cavity 43, covers in the middle part of lever 8
It on lever shaft 7, and is blocked by flange screw and prevents lever 8 from deviating from, 8 one end 81 of lever is directed at 3 rear end of thimble, the other end
82 are connected on the piston rod 121 of cylinder 12 by screw 13, and cylinder 12 drives the other end 82 and lever one end 81 is made to swing and drive
Dynamic thimble 3 valve nozzles or leaves mandril 3 forward.
Above-mentioned cylinder 12 is fixed on bracket 44 by air cylinder support screw 11 by the down-set bracket 44 of above-mentioned rear flange 42
On.
Preferably, screw thread is set on above-mentioned rear flange 42, is threadedly coupled with adapter head 1, using flanged joint, be can adjust suitable
With the position between first 1 and bracket 44, depth is threaded by control to control 12 position of cylinder.In addition, using flanged joint
Benefit be can with lesser torque generate opposite thread connect big sealing surface contact force so that assembly when be easy.
