Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings.Herein it should be noted that
Explanation for these embodiments is used to help understand the utility model, but does not constitute to restriction of the present utility model.This
Outside, as long as technical characteristic involved in each embodiment of the utility model disclosed below does not constitute conflict each other
It can just be mutually combined.
As Figure 1-3, core-pulling mechanism under a kind of handle injection mold diclinic side of duplicator, including correspondence handle plastic
Two taper pin core pulling components that grooves on two sides both sides are set, and correspondence handle plastic the core core pulling group that sets of tiltedly lower blind hole
Part, the taper pin core pulling component includes sliding block, taper pin 6 and pull bar 8, and the die cavity of handle plastic includes moving platen 10 and set
Split pattern block 2 on the moving platen 10, the sliding block includes the first sliding block 3 and the second sliding block 7, the He of the first sliding block 3
Second sliding block 7 is connected with the split pattern block 2 respectively, and the taper pin 6 is through solid plate 4, the sliding block and described dynamic
Template 10, the pull bar 8 is connected with the sliding block；The core core pulling component includes the connecting rod with the first rack 13, with
And the bearing pin 11 of the fixed connecting rod and core, the connecting rod is with the taper pin 6 with same tilt degree, the taper pin 6
On be also equipped with the second rack 12, first rack 13, second rack 12 coordinate with gear, drive the connecting rod and
The synchronizing moving of taper pin 6.
Wherein, the outside of pull bar 8, which is provided with the moving platen 10 on the downside of spring 9, the sliding block, is provided with spacer pin 1.
During die sinking, undercut core pulling is realized with movable slider by taper pin 6；Meanwhile, the tiltedly lower blind hole of handle plastic is de-
Also need to complete core pulling before mould, otherwise not only increase is stripped difficulty, and plastic surface galling can be influenceed into plastic part quality.Matched moulds
Afterwards, spring 9 is compressed；After die sinking, under the tension force effect of spring 9, the first sliding block 3 and the second sliding block 7 are in separated limit position
Put (spacing by spacer pin), it is ensured that taper pin smoothly enters inclined hole during matched moulds.
