Description
Technical field
The utility model is related to a kind of mould, more particularly, to a kind of ejector pin of die set layering type attachment structure.
Background technology
Push rod is common a kind of accessory in mould, and push rod is mainly used to from punch-pin or cavity plate in the modern designs of plastics and compression mod
The middle product by injection moulding departs from punch-pin or cavity plate.Fixed form between push rod and mould is typically that will be inserted at the top of push rod
In mould, through hole is opened up in push rod side, pin is squeezed into mould side, pin is squeezed into mould and top are realized in push-rod hole
, although this mode can meet fixed function, there are some defects in the stationary positioned between bar：It is necessary when the 1st, assembling
Push rod is rotated to through hole to align with pin and can just squeeze into pin, is wasted time and energy, bad assembling；2nd, squeeze into after pin and add in the later stage
When work or work, it is concentrated mainly on pin at stress, once pin is by excessive force deformation or damage, pin must be through
Crossing destruction could take out, and be difficult to avoid that mould and push rod also will be destroyed during now write off nail, gently then the later stage needs repairing
Mould, it is heavy then directly scrap, there is larger potential safety hazard.
Utility model content
Regarding to the issue above, the utility model aims to provide a kind of ejector pin of die set layering type attachment structure, and its is simple in construction
It is compact, it is safe and reliable, mould and push rod are fastenedly connected by way of retainingf key is set, can bear bigger power without
It is damaged, and convenient disassembly.
The technical solution of the utility model is a kind of ejector pin of die set layering type attachment structure, including push rod and mould, described
By retainingf key and mode connects for screw between push rod and mould, the mould lower surface offers the duct inserted for push rod, described
Mould side is offered in the middle part of the conduit inserted for retainingf key, conduit and duct insertion, and conduit bottom surface is provided with for screw locking
Screwed hole, have the through hole passed through for screw on retainingf key, lead to the hole site is corresponding with screw thread hole site, the push rod upper side
Offer the groove being adapted with retainingf key front end.
It is preferred that, the push rod bottom is provided with the oblique liftout attachment for the oblique ejection of push rod.
The utility model is simple and compact for structure, safe and reliable, by mould and push rod by way of setting retainingf key
It is fastenedly connected, bigger power can be born without being damaged, and convenient disassembly.

Embodiment
Below in conjunction with the accompanying drawings, the utility model is described in further detail.
As shown in Figures 1 to 7, the technical solution of the utility model is a kind of ejector pin of die set layering type attachment structure, including
Push rod 1 and mould 2, are connected between the push rod 1 and mould 2 by retainingf key 3 and screw 4, and the lower surface of mould 2 is offered
The duct 5 inserted for push rod 1, the side of mould 2 offers the conduit 6 inserted for retainingf key 3, and the middle part of conduit 6 is passed through with duct 5
Logical, the bottom surface of conduit 6, which is provided with, the through hole passed through for screw 4, lead to the hole site on the screwed hole 7 locked for screw 4, retainingf key 3
Corresponding with the position of screwed hole 7, the upper side of push rod 1 offers the groove 8 being adapted with the front end of retainingf key 3.
It is preferred that, the bottom of push rod 1 is provided with the oblique liftout attachment 9 for the oblique ejection of push rod 1.
In use, push rod 1 is inserted in the duct 5 of mould 2, by 8 pairs of sides of conduit 6 to mould 2 of groove of push rod 1,
Retainingf key 3 is put into the conduit 6 of mould 2, the front end of retainingf key 3 is caught in the groove 8 of push rod 1, retainingf key 3 is passed through with screw 4
Be locked in screwed hole 7, completed with this to push rod 1, mould 2, the three of retainingf key 3 fixation, this fixed form relative to
Pin fixed form before can bear bigger power without being damaged, even unexpected wreck, and must conveniently can also take out
Retainingf key 3, changes a new retainingf key 3, safe and reliable in use.
The above, is only better embodiment of the present utility model, not makees any formal limit to utility model
System, it is every according to know-why of the present utility model to any simple modification made for any of the above embodiments, equivalent variations or modification,
In the range of still falling within technical solutions of the utility model.
