The internal edge of benevolence is provided with flat thimble, and flat thimble is connected by running through mode with male die core；The top side of the male die core
Moulding is provided with, and moulding is connected by injection molding manner with male die core；Runner is provided on the outside of the sprue mold insert,
And one end of runner is connected by embedded mode with sprue mold insert；The bottom side of the runner is provided with dome needle；The injection
The cast gate junction of part and sprue mold insert is set as shearing basic point；The junction of the flat thimble and moulding is set as stress
Point.
As advanced optimizing for the technical program, dome needle described in a kind of automatic Duan Jiao mechanisms of mold side gate of the present invention
Resilient rubbber cushion is provided with, and the diameter of resilient rubbber cushion is more than the diameter on dome needle top with the junction of runner.
As advanced optimizing for the technical program, runner described in a kind of automatic Duan Jiao mechanisms of mold side gate of the present invention
One end is applied in the top of sprue mold insert, and is applied in the runner in sprue mold insert in horn-like.
As advanced optimizing for the technical program, moulding described in a kind of automatic Duan Jiao mechanisms of mold side gate of the present invention
With the cast gate junction in sprue mold insert basic point is sheared for right angle.
As advanced optimizing for the technical program, cast gate edge described in a kind of automatic Duan Jiao mechanisms of mold side gate of the present invention
The outer wall on part top is the inclined-plane of degree.
Due to the utilization of above-mentioned technical proposal, the present invention has following advantages compared with prior art：
Runner is ejected from mold cavity during by the effect of dome needle, mold is withstood.
By the effect of sprue mold insert, sprue mold insert is made to play the role of cutting off cast gate in a device.
By the effect of flat thimble, product is ejected from mold cavity during mould ejection.
A kind of automatic Duan Jiao mechanisms of mold side gate of the present invention program have automatic break gate, time saving and energy saving, saving
