Oblique top knock-out gear 14 and small straight die ejecting mechanism 15 clamp injecting products 12, and product is under the action of self-deformation out of master mold
It is detached from the back-off of parting, oil cylinder continues to drive ejection movement in next die sinking movement, and big oblique top 13 is led along big oblique top
The direction of rail 27 continues to move, at the same time angle ejector rod guide sleeve 17, small oblique top 18, oblique jacking guide bar 19, oblique top link block 20 with
And oblique top head 21 and straight jacking block 24, small straight top 25 and straight top stem casing 26 are pressed respective respectively under the action of its two-sided guide rail 16
Orbital path realize relatively independent die sinking movement, product is ejected from male model at this time；When on Double-ejection seesaw 30
Bearing 31 touch wear-resistant block after, Double-ejection seesaw 30 is rotated along its rotary shaft 32, and upper ejector retainner plate 7 sticks up in Double-ejection
A distance is moved again up under the action of wraping plate 30, drives small jacking block 6 that product is detached from from big jacking block 8, until lower top
10 stroke limit column of needle plate arrives at male model bottom surface, and die sinking at this time and ejection movement are completed, after taking out injecting products 12, nitrogen gas spring
33 prevent jacking needle plate retroversion, and master mold back stitching gasket pushes back back stitching completion molding, so that master mold drag hook 29 and big oblique top drag hook 28 are again
Secondary to be engaged, this is entire die sinking and clamping process.
Specific embodiment described herein is only an example for the spirit of the invention.The neck of technology belonging to the present invention
The technical staff in domain can make various modifications or additions to the described embodiments or replace by a similar method
Generation, defined range that however, it does not deviate from the spirit of the invention.
