Degree.
As an improvement：The spring groove passes through the second ejector retainner plate.
Spring groove is simple through the processing of the second ejector retainner plate, it is not necessary to accurate processing, saves cost.
As an improvement：The insert is provided with T-slot, and the oblique top end is provided with T-rail.
The one end of oblique top away from rear cavity is slidably matched with insert, during lifter ejection, ensures oblique top close to the one of rear cavity
End is constant with the distance of rear cavity, will not draw bad product.
As an improvement：The ejector retainner plate is provided with limited post close to the side of front cavity.
When lifter ejection is to predetermined length, limited post contacts with front cavity, prevents that lifter ejection stroke is long, and damage is oblique
Top.
As an improvement：Side of the bottom plate away from front cavity is concordant with side of the front template away from rear cavity.
Facilitate model sheetinstallat.
By adopting the above-described technical solution, compared with prior art, the utility model has the advantages that：It is simple in construction tight
Gather, movement travel is small, and critical piece is arranged in front template, avoids mould blocked up overweight, saves cost, in addition moving component
Few, reliable in action, stability are good.
