Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain
This utility model, is not used to limit this utility model.
Refer to Fig. 2-5, a kind of sliding block core pulling structure of the present utility model, include slipper block loose core die ontology,
It is provided with the die for shaped article 10 on this slipper block loose core die ontology, product 10 is carried out slide block assembly and the use of the demoulding
In the ejector pin component carrying out ejecting by product 10；Be additionally provided with on this slipper block loose core die ontology be connected with ejector pin component, for
Prevent ejector pin component from supporting the Collsion proof safety part 1 that slide block assembly collides when slide block assembly does not slides and puts in place；This slide block group
The clearance position 2 for Collsion proof safety part 1 being carried out empty avoiding is offered on part.
This Collsion proof safety part 1 is safty pin, safety post or safety pole, prevents hitting empty avoiding as long as it meets, is preferably
Safty pin, as shown in Figure 2-5.A diameter of more than 6mm of this Collsion proof safety part 1 so that it is have certain mechanical strength, prevents
Fracture during hitting.This ejector pin component includes ejector retainner plate 3 and the thimble 4 being connected with this ejector retainner plate 3, and the quantity of this thimble 4 is 2
Above, as in figure 2 it is shown, this quantity depends on the shape of shaped article 10.
Wherein, this Collsion proof safety part 1 is connected with ejector retainner plate 3 and be arranged in parallel with thimble 4, and Collsion proof safety part 1 is with ejector retainner plate 3
Motion.This slide block 5 assembly includes slide block insert 6 that slide block 5 is connected with slide block 5, in inserting this slide block 5, band movable slider 5 is sliding
The latch 7 of row, as it is shown on figure 3, this latch 7 is preferably taper pin, during latch 7 stretching motion, band movable slider 5 horizontally slips.This empty avoiding
Position 2 is opened in slide block insert 6, such as Fig. 3-5, for empty avoiding Collsion proof safety part 1.This die includes the front cavity 8 cooperated
And rear cavity 9, this front cavity 8, rear cavity 9 and slide block insert 6 form the molding cavity of shaped article 10, for the one-tenth of product 10
Type.
Referring specifically to Fig. 4-5, when ejector pin component ejects shaped article 10, put in place as slide block assembly slides, Collsion proof safety part 1
Move by clearance position 2 empty avoiding when ejecting with ejector pin component, shaped article 10 is ejected by ejector pin component smoothly；As slide block assembly is not slided
Row puts in place, and Collsion proof safety part 1 moves with ejector pin component when ejecting, and Collsion proof safety part 1 does not arrives clearance position 2 empty avoiding, can effectively hinder
Only ejector pin component moves further, prevents ejector pin component from supporting slide block assembly and collides, improves the safety of mould self
Energy.Below as a example by crashproof safety member 1 is as safty pin, implement step as follows:
Such as Fig. 4, after product 10 has been molded, mould is opened, slide block 5 in the drive lower slider of taper pin to fixed journey system position
Putting, now the clearance position 2 of safty pin is directed at safty pin position；
Such as Fig. 5, after safty pin is to upper clearance position 2, the region that the most fully out thimble of slide block insert 64 ejects, so push up
Pin 4 ejects under the driving of injection machine ejector retainner plate 3 and would not knock slide block insert 6, and product 10 is pushed up by following thimble 4 simultaneously
Go out；
As there is accident, slide block 5 does not slide and puts in place, i.e. safty pin does not arrive clearance position 2 position, safty pin and slide block
5 support, and effectively stop thimble 4 to move further, prevent thimble 4 from supporting slide block insert 6 and collide, because the effect of safty pin keeps away
Exempt from the risk that slide block insert 6 bumps against with thimble 4.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Any amendment, equivalent and the improvement etc. made within the spirit of utility model and principle, should be included in this utility model
Protection domain within.
