Surely one end of rotating shaft is connected with, the other end of the rotating shaft is installed with acting gear, the acting gear position by bearing pin
In in kerve, and the gear that does work engages with the bar shaped tooth of push rod, and the lower surface of the cope plate is fixedly connected with core rod, cope plate
Upper surface insertion water conservancy diversion tool is installed, the upper end of water conservancy diversion tool is provided with injection machine, and the lower surface of cope plate is fixedly connected
There is guide rod, the end face of guide rod is provided with bar shaped tooth, and guide rod is installed with chute for activity.
Further, respectively one chute of arrangement, the front end of a chute are communicated with gear grooved for the both sides of the groove position, another cunning
The rear end of groove is communicated with gear grooved.
Further, the front/rear end of the push rod is equipped with bar shaped tooth.
Further, the width of the chute is more than the width of gear grooved.
Further, the side wall insertion of the gear grooved is provided with bearing, and the inner ring of bearing is fixedly mounted with rotating shaft.
Compared with prior art, the present invention has the advantages that：The present apparatus passes through guide rod band while mold is removed
Nutating gear rotate, travelling gear by rotating shaft drive acting gear rotate in same direction so that the direction of motion of push rod also with
The reversing of motion of guide rod is consistent, and so as to directly eject moulding from die cavity, simple and fast is time saving and energy saving, without upset
Mould etc. operates, and can increase substantially the operating efficiency of operative employee.

Embodiment
To be easy to understand the technical means, the inventive features, the objects and the advantages of the present invention, with reference to
Embodiment, the present invention is expanded on further.
As Figure 1-5, a kind of workpiece automatic ejection injection mold, including lower template 1 and cope plate 17, the lower template
1 upper surface is provided with die cavity 2, and internal module 3 is installed with die cavity 2, and the upper surface of the internal module 3 is provided with groove position 4, and
The upper surface both sides of internal module 3 are provided with chute 5, and the end face of the chute 5 is communicated with gear grooved 6, and the lower end of the groove position 4 connects
It is connected with kerve 7, and through being connected with push rod 8 in kerve 7, the end face of the push rod 8 is bar shaped toothing, in the gear grooved 6
