Specific embodiment
As Figure 1-Figure 8, present invention slider secondary core-pulling mechanism, designing points are: since there are small recessed on product
Hole realizes that small shrinkage pool forms by the way that small salient point 20 is arranged in top shoe, but after shaping, due to the presence of small salient point, upper cunning
Block can not move, it is therefore desirable to and Design assistant mechanism realizes that the smooth and product of small salient point is detached from, to achieve the above object, this hair
Bright secondary core-pulling mechanism includes take-up housing 1, slider head 2, and the slider head 2 is equipped with slider bore 3, sets in the slider bore 3
There are top shoe 4 and sliding block 5, top shoe is equipped with small salient point, and inclined-plane is equipped between the top shoe 4 and sliding block 5 and is oriented to
Mechanism, the take-up housing 1 and sliding block 5 connect, and the sliding block 5 is connect with take-up housing 1, the take-up housing 1 and cunning
Delay linkage mechanism is equipped between build 2, the take-up housing 1 is connect with external driving mechanism.Working principle is: driving outside
Motivation structure (usually oil cylinder 19) drives take-up housing mobile, drives sliding block is mobile first to retreat, between top shoe and sliding block
The oblique mechanism sliding block that is move backward after, top shoe can fall automatically, can until top shoe is completely disengaged with small shrinkage pool
When to move freely, slider head could be moved, that is, drive slider head mobile by delay linkage mechanism.
It is bonded between the top shoe 4 and sliding block 5 by inclined inclined-plane, the sliding block 5 is equipped with sliding slot
6, the top shoe 4 is equipped with draw runner 7,6 sliding fit of the draw runner 7 and sliding slot.In order to guarantee that top shoe and sliding block are mobile
Process is stable and realizes the purpose that top shoe falls, in such a way that inclined-plane is bonded, neither interference mutually sliding, and can be
Sliding block realizes that top shoe falls after moving back, and is passing through the cooperation between sliding slot and draw runner, it is ensured that top shoe and downslide
Block movement is reliable and stable, effectively avoids shaking.
The delay linkage mechanism includes pulling plate 8, and 8 front end of pulling plate is equipped with block 9, and the slider head 2 is set
There is delay slot 10, the pulling plate 8 is mounted on take-up housing 1, and block 9 fits snugly in delay slot 10.It is real by delay slot
Existing delay feature, when take-up housing starts mobile, pulling plate is and then moved, and the block of pulling plate front end slides in delay slot, is not done
Slider head is related to, when realizing that block covers the stroke of delay slot after falling on predetermined position under top shoe, offsets, drives with delay slot
Slider head is mobile.
As corrective measure, the take-up housing 1 is equipped with card slot 11, is equipped with link block 12 in card slot 11, link block 12 with
Oil cylinder 13 connects.By link block connection sliding block seat and oil cylinder, it is easily installed.
As an improvement, being equipped with positioning mechanism between the take-up housing 1 and slider head 2.The positioning mechanism refers to cunning
Block 1 is equipped with cutting 14, and the slider head 2 is equipped with slot 15, and the cutting 14 cooperates the cutting in slot 15
14 are equipped with locating slot 16, and slider head 2 is equipped with bolt 17, and 17 activity of bolt cooperates the side wall in slider head 2, described
Cutting 14 is equipped with the notch 18 cooperated with bolt 17.The movement of slider head is also to have travel limit, cannot be moved without limitation, because
This setting positioning mechanism, the bolt of positioning mechanism are mounted on lathe, are in a fixed position, and when bolt movement, make notch more than 18
When bolt is aligned, bolt injects notch and prevents the movement of slider head.Entire top shoe terminates with product disengaging movement.
