Description
Technical field
This utility model is related to die-casting technique field, particularly to a kind of automobile Hpdc mould precasting pin.
Background technology
The high speed development of Chinese national economy, necessarily be unable to do without the cooperation of the Die Casting Industry closely coupled with it, because having
Reducing energy consumption, reduce pollution, product size is stably tight, and outward appearance is beautiful, the advantage such as dense structure, die casting is necessarily following
Bigger space quotas are occupied in development.
In magnalium Hpdc, magnalium die casting is the magnalium liquid, is propelled by drift high speed
In the whole die cavity of mould, obtain required product, the structure design which results in mould determines the quality of die-cast product, and
The inside sbrinkage blowhole of die-cast product is that exist always, and is difficult to overcome solution.A lot of automobile component products are former due to structure
Because being required for processing through hole and screwed hole, such sbrinkage blowhole will come out, and whether from outward appearance or functionally all makes
Become very big negative effect；Just arisen at the historic moment by this precasting pin, the ratio that it exposes after can greatly reducing sbrinkage blowhole processing,
And because precasting pin scalds under the high pressure high rate of fire of stream in magnalium, its life-span is limited, will occur in process of production frequently
Disconnected pin；For ease of changing precasting pin, its structure is substantially designed to preposition pin, is locked by thread, but works as precasting pin
It is difficult to take out from fracture of root, or even the pin remaining within core rod cannot be taken out, need to be burnt with gas welding torch, often damage
The impact of bad mould produces output, wastes the substantial amounts of energy simultaneously and brings security risk.This utility model is therefore.
Utility model content
In order to solve problems of the prior art, this utility model purpose is to provide a kind of automobile Hpdc mould
Use precasting pin, its structure is simple, it is possible to resolve the problem that precasting pin fracture of root is difficult to take out in core rod body.
Based on the problems referred to above, the technical scheme that this utility model provides is：
Automobile Hpdc mould precasting pin, including precasting pin body, described precasting pin body includes fixed part and pre-
Casting portion, described fixed part is threadeded with core rod body, and described core rod stretches out originally in vitro in described precasting portion, described precasting pin body
Inside it is provided with preformed hole, described preformed hole extends to described precasting portion by the end of described fixed part, the length of described preformed hole is big
In the length of described fixed part, the diameter of described preformed hole is less than the diameter of anti-tooth extractor.
In some embodiments wherein, a diameter of 6～8mm of described preformed hole.
In some embodiments wherein, the length of described preformed hole is the 2/3 of described precasting pin body length.
In some embodiments wherein, described preformed hole is coaxially disposed with described precasting pin body.
Compared with prior art, the utility model has the advantages that：
Using the technical solution of the utility model, it is provided with preformed hole in the precasting portion of precasting pin body, when precasting pin occurs
During fracture, with hammer, anti-tooth extractor being knocked in the preformed hole of precasting pin, then rotating anti-tooth extractor with spanner, thus rotating
Go out to stay the originally remaining in vivo precasting pin of core rod, easy to operate, time saving and energy saving, hard labor simultaneously prevents mould from damaging, and improves mould
Service life.
Brief description
In order to be illustrated more clearly that the technical scheme of this utility model embodiment, below will be to required in embodiment description
The accompanying drawing using is briefly described, and drawings in the following description are only some embodiments of the present utility model, for ability
For the those of ordinary skill of domain, on the premise of not paying creative work, can also be obtained other attached according to these accompanying drawings
Figure.
Fig. 1 is the structural representation of this utility model automobile Hpdc mould precasting pin embodiment；
Wherein：
1st, fixed part；
2nd, precasting portion；
3rd, preformed hole.
Specific embodiment
Below in conjunction with specific embodiment, such scheme is described further.It should be understood that these embodiments are for illustrating
This utility model and be not limited to limit scope of the present utility model.The implementation condition adopting in embodiment can be according to concrete producer
Condition do and adjust further, not marked implementation condition is usually the condition in normal experiment.
Referring to Fig. 1, it is structural representation of the present utility model, a kind of automobile Hpdc mould precasting pin is provided, bag
Include precasting pin body, precasting pin body includes fixed part 1 and precasting portion 2, and fixed part 1 is threadeded with core rod body, is fixing
The outer wall in portion 1 is provided with external screw thread, and core rod is stretched out in precasting portion 2, and this is external, and when precasting pin breaks at core rod, this is internal, for the ease of
Precasting pin is taken out, is originally provided with preformed hole 3 in vivo in precasting pin, preformed hole 3 is blind hole and extends to precasting portion 2 by fixed part 1,
The length of preformed hole 3 is more than the length of fixed part 1, and the diameter of preformed hole 3 is less than the diameter of anti-tooth extractor.
A diameter of 6～8mm of preformed hole 3, can be arranged according to the diameter of anti-tooth extractor.
Preferably, the length of preformed hole 3 is the 2/3 of precasting pin body length, and is coaxially disposed with precasting pin body.
When precasting pin occurs fracture, with hammer, anti-tooth extractor is knocked in the preformed hole of precasting pin, then revolved with spanner
Turn anti-tooth extractor, thus rotate staying the originally remaining in vivo precasting pin of core rod.
Examples detailed above is only that technology design of the present utility model and feature are described, its object is to allow and is familiar with technique
People is to will appreciate that content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All
The equivalent transformation being done according to this utility model spirit or modification, all should cover protection domain of the present utility model it
Interior.
