Above-mentioned chute is set to straight-line groove or curved groove and moves to cooperate with the blank forward block and all can.
With cover half that described dynamic model cooperates be provided with one with the 4th inclined-plane of misfit mutually, reset baffle block first inclined-plane.
Described sliding seat bottom is connected with push rod.
The course of work of the present invention is described below:
During matched moulds, reset link stopper under the 4th ramp effect on the cover half that dynamic model cooperates to spring block move and holddown spring and and knife rest withdraw, drive the initial position that pin is withdrawn and is limited in stopper slot one end, simultaneously, sliding seat and push rod pressurized are got back to initial position, and blade is also got back to initial position under the torsion spring effect; After injection moulding was finished, during die sinking, dynamic model separated with cover half, and spring unclamps, and reset baffle block stretches out with knife rest under spring action, and pin moves to the operating position of the stopper slot other end in stopper slot; Sliding seat upwards rises under the push rod effect, by the 3rd ramp effect in the vertical rod blank forward block is pushed ahead, and cast gate is also downcut in the rotation of impulsion blade, take off the pipe fitting that downcuts cast gate after, matched moulds goes round and begins again again.
The present invention has improved the production efficiency of pipe fitting mold, has reduced the production cost, and processing for the automation of pipe fitting mold provides a kind of suitable equipment.
