For achieving the above object; the technical solution used in the present invention is: a kind of injection mold of driven by clutches flat bar; comprise cover half; dynamic model; described dynamic model comprises moving platen; be arranged on the dynamic model seat of described moving platen bottom; be arranged on the ejecting mechanism on the described dynamic model seat with can giving oscilaltion; described mould also has be used to the mouth of a river that sprays into injection moulding liquid; the centre of described moving platen offers first groove consistent with the outline of described driven by clutches flat bar; described moving platen also offers the first through hole that vertically distributes at the leading section that is positioned at described the first groove; rearward end at described the first groove also offers the first keyway; described ejecting mechanism comprise the delivery piece; also be fixedly connected with on the upper surface of described delivery piece and be provided with the push rod that can insert described the first through hole; offer on the described cover half respectively and described the first through hole; the second through hole of the corresponding setting of described the first keyway; the second keyway, described cover half also comprise the pumping pin that can insert ordinatedly in described the second through hole and described the first through hole; can insert ordinatedly the piece of taking out in described the second keyway and described the first keyway.
Preferably, offer accordingly respectively the second groove, the 3rd groove on the die joint of described moving platen, described cover half, the setting that is connected with described the first groove of described the second groove, described the second groove, described the 3rd groove match and form the described mouth of a river.
Preferably, the upper end of described cover half also is fixedly connected with and is provided with briquetting.
Further preferably, the bottom of described upper end of taking out piece and the described briquetting setting that is fixedly connected.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages: by offering first groove consistent with the driven by clutches flat rod model of required injection moulding at moving platen and offering accordingly the first through hole, the first keyway, and pumping pin is set on cover half accordingly and takes out piece, after closely cooperating, cover half and dynamic model can form the near closed hollow ring of the driven by clutches flat rod model of required injection moulding, by in the mouth of a river, injecting injection moulding liquid, behind the injection moulding cooling forming, pull out pumping pin and take out piece, take off cover half, upwards lift the delivery piece, the injection moulding good model can be ejected the first groove, make things convenient for delivery.This mould structure is simple, and is easy to operate, practical.

The specific embodiment
Further set forth structure of the present invention below in conjunction with accompanying drawing.
Shown in Fig. 1-3, a kind of injection mold of driven by clutches flat bar, comprise dynamic model 1, cover half 2, dynamic model 1 is mainly by moving platen 12, dynamic model seat 11, ejecting mechanism three parts consist of, ejecting mechanism vertically is arranged on to oscilaltion on the dynamic model seat 11, moving platen 12 is arranged on the upper surface of dynamic model seat 11, the centre of moving platen 12 offers the first groove 14, the outer contour shape size of the first groove 14 is consistent with the outline of the driven by clutches flat rod model of required injection moulding, moving platen 12 also offers the first through hole 15 that vertically distributes at the leading section that is positioned at the first groove 14, rearward end at the first groove also offers the first keyway 16, the first through hole 15, through hole on the position of the first keyway 16 and the driven by clutches flat rod model and the position of keyway are corresponding, ejecting mechanism comprises delivery piece 13, be fixedly connected with on the upper surface of delivery piece 13 and be provided with the push rod that can insert ordinatedly in the first through hole 15, offer on the cover half 1 respectively and the first through hole 15, the second through hole 22 of the first keyway 16 corresponding settings, the second keyway 23, also be provided with pumping pin 25 on the cover half 1, take out piece 26, when cover half 2 closely cooperates mutually with dynamic model 1, pumping pin 25 can insert in the first through hole 15 by the second through hole 22 ordinatedly, takes out piece 26 and can insert the first keyway 16 by the second keyway 23 ordinatedly.The upper end of solid plate 12 also is fixedly connected with and is provided with briquetting, in the present embodiment briquetting with take out piece 26 and be wholely set, be specially on the bottom that the upper end of will take out piece 26 is fixedly connected on briquetting, take out like this piece 26 and also be fixed to connect and be arranged on the cover half 2.
