Abstract
The utility model discloses a kind of Puller pin of improvement, including：Puller pin body and plunger, the plunger has first end face, second end face and side, and the diameter of the first end face is less than the diameter of the second end face, and the side is the cambered surface that second end face is extended to by first end face；The first end face of the plunger is arranged at the first end of the Puller pin body, and is connected to by being arranged at the ledge structure of the Puller pin body first end on the Puller pin body；The ledge structure at least makes the product after shaping also to form a corresponding ledge structure, and the ledge structure top on the product is wider than bottom.By setting ledge structure in the Puller pin body first end, so that the product after shaping can also form a corresponding ledge structure, ledge structure top on product is wider than bottom, when Puller pin is deviate from from runner condensate, ledge structure can play a part of buffering, so as to effectively avoid step oral area from bursting apart.
Description
Technical field
A kind of Puller pin is the utility model is related to, more particularly to a kind of Puller pin of improvement, belongs to die apparatus technology neck
Domain.
Background technology
At present, injection mold industry is undergoing continuous technological innovation and transformation, in three template dies using point type sprue bush
In, Puller pin is used to the runner of hole irrigation oral area being temporarily fixed to runner plate, and cast gate and shaped article are cut off.It is existing
In technology, the fore-end of Puller pin is back-off shape, can be stripped the runner of hole irrigation oral area from point type sprue bush by force.
The Puller pin in three template dies, which is generally in the form of, in the prior art is consolidated Puller pin by Puller pin briquetting and bolt in three template dies
It is scheduled on fixed clamping plate, when mould all pulls open, fixed clamping plate separates with runner plate, at this moment because Puller pin is fixed on cover half
On bottom plate, runner plate pulls runner from Puller pin.But because the plunger of Puller pin of the prior art is back-off
Shape, i.e. Puller pin are that the big root of head is small, and Puller pin so blocks sectional area bigger in runner for runner, and are made
The sectional area size of runner is uneven, in addition such structure when running into the product that moulding material is hard and appearance requirement is high,
Originally Puller pin when being separated with runner pulling, easily consider to be worth doing, and material bits can not only enter in air stream enter runner to product appearance production by pull-out material
It is raw to influence, and irreversible damage can be caused to mould, the bad ratio of briquetting of product is not only increased, can also cause to produce
The increase of cost.
Utility model content
Main purpose of the present utility model is to provide a kind of Puller pin of improvement, and product after shaping can form one
Ledge structure, the ledge structure top on product are wider than bottom, enabling waste material caused by property cut runner, so as to overcome
The deficiencies in the prior art.
To realize foregoing purpose of utility model, the technical solution adopted in the utility model includes：
The utility model provides a kind of Puller pin of improvement, including：Puller pin body and plunger, the plunger have the
End face, second end face and side, and the diameter of the first end face is less than the diameter of the second end face, the side is served as reasons
First end face extends to the cambered surface of second end face；The first end face of the plunger is arranged at the first end of the Puller pin body
Portion, and be connected to by being arranged at the ledge structure of the Puller pin body first end on the Puller pin body；Described
Stage structure at least makes the product after shaping also to form a corresponding ledge structure, under the ledge structure top ratio on product
Portion is wide.
Further, the diameter of the ledge structure is less than the diameter of the Puller pin body first end, and described
The diameter of ledge structure is more than the diameter of the plunger first end face.
Further, the diameter of the Puller pin body first end: the diameter of ledge structure: plunger first end face
A diameter of (1.5~2): (1.2~1.4): 1.
Further, the diameter of the plunger first end face and the diameter ratio of second end face are 1: 1.5~3.
Further, the ratio between the thickness of the step mechanisms and the thickness of plunger are 1: 5~10.
Further, the longitudinal section of the plunger is trapezoidal, and the second end face of the plunger and the side are smooth
Connection.
Compared with prior art, include the advantages of the utility model：The Puller pin of improvement provided by the utility model, passes through
Ledge structure is set in the Puller pin body first end so that the product after shaping can also form a corresponding step
Structure, the ledge structure top on product is wider than bottom, and when Puller pin is deviate from from runner condensate, ledge structure can play
The effect of buffering, so as to effectively avoid step oral area from bursting apart.

Embodiment
In view of deficiency of the prior art, inventor is able to propose that this practicality is new through studying for a long period of time and largely putting into practice
The technical scheme of type.The technical scheme, its implementation process and principle etc. will be further explained as follows.
The utility model provides a kind of Puller pin of improvement, including：Puller pin body and plunger, the plunger have the
End face, second end face and side, and the diameter of the first end face is less than the diameter of the second end face, the side is served as reasons
First end face extends to the cambered surface of second end face；The first end face of the plunger is arranged at the first end of the Puller pin body
Portion, and be connected to by being arranged at the ledge structure of the Puller pin body first end on the Puller pin body；Described
Rank matter structure at least makes the product after shaping also to form a corresponding ledge structure, the ledge structure top ratio on product
Bottom is wide.
As follows will be further to works such as the technical scheme, its implementation process and principles with reference to accompanying drawing and specific implementation case
Illustrate.
Referring to Fig. 1, a kind of Puller pin of improvement, can include：Puller pin body 1 and plunger 2, the plunger 2 have
