Abstract
The invention discloses automobile Hpdc mould precasting pin, including precasting pin body, described precasting pin body includes fixed part (1) and precasting portion (2), described fixed part (1) is threadeded with core rod body, described precasting portion (2) stretches out described core rod, and this is external, described precasting pin is the most internal is provided with preformed hole (3), described preformed hole (3) is extended to described precasting portion (2) by the end of described fixed part (1), the length of described preformed hole (3) is more than the length of described fixed part (1), the diameter of described preformed hole (3) is less than the diameter of anti-tooth extractor.The automobile Hpdc mould precasting pin that the present invention provides, it is possible to resolve precasting pin fracture of root is difficult to the problem taken out in core rod body, improves the service life of die casting.
Description
Technical field
The present invention relates 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 and the coordinating, because having of its closely coupled Die Casting Industry
Reduction energy consumption, reduce and pollute, product size is stably tight, the advantages such as outward appearance is beautiful, dense structure, and die casting will be necessarily in future
Development occupies bigger space quotas.
In magnalium Hpdc, magnalium die casting is the magnalium of liquid, drift propel at a high speed
In the whole die cavity of mould, it is thus achieved that 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 to 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, whether the most all make from outward appearance
Become the biggest negative effect；Thus precasting pin just arises at the historic moment, 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 at 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 when precasting pin
It is difficult to take out from fracture of root, even cannot take out the pin remained within core rod, need to burn with gas welding torch, often damage
The impact of bad mould produces output, wastes the substantial amounts of energy simultaneously and brings security risk.The present invention is therefore.
Summary of the invention
In order to solve problems of the prior art, it is an object of the present invention to provide a kind of automobile Hpdc mould with pre-
Casting pin, its simple in construction, 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, present invention provide the technical scheme that
Automobile Hpdc mould precasting pin, including precasting pin body, described precasting pin body includes that fixed part is with pre-
Casting portion, described fixed part threadeds with core rod body, and described core rod is stretched out in described precasting portion, and this is the most external, described precasting pin body
Inside being provided with preformed hole, described preformed hole is extended to described precasting portion by the end of described fixed part, and 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 the 6 of described preformed hole～8mm.
In some embodiments wherein, the 2/3 of a length of described precasting pin body length of described preformed hole.
In some embodiments wherein, described preformed hole is coaxially disposed with described precasting pin body.
Compared with prior art, the invention have the advantage that
Use technical scheme, be provided with preformed hole in the precasting portion of precasting pin body, when precasting pin ruptures
Time, with hammer, anti-tooth extractor is knocked in the preformed hole of precasting pin, then rotate anti-tooth extractor with spanner, thus rotate and stay
At the precasting pin of these internal remnants of core rod, easy to operate, time saving and energy saving, hard labor simultaneously prevents mould from damaging, and improves making of mould
Use the life-span.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme of the embodiment of the present invention, required use in embodiment being described below
Accompanying drawing be briefly described, below describe in accompanying drawing be only some embodiments of the present invention, skill common for this area
From the point of view of art personnel, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of automobile Hpdc mould precasting pin embodiment of the present invention；
Wherein:
1, fixed part；
2, precasting portion；
3, preformed hole.
Detailed description of the invention
Below in conjunction with specific embodiment, such scheme is described further.Should be understood that these embodiments are for illustrating
The present invention and be not limited to limit the scope of the present invention.The implementation condition used in embodiment can be done according to the condition of concrete producer
Adjusting further, not marked implementation condition is usually the condition in normal experiment.
See Fig. 1, for the structural representation of the present invention, it is provided that a kind of automobile Hpdc mould precasting pin, including pre-
Casting pin body, precasting pin body includes fixed part 1 and precasting portion 2, and fixed part 1 is threadeded with core rod body, at fixed part 1
Outer wall 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 by pre-
Casting pin takes out, and at this internal preformed hole 3 that is provided with of precasting pin, preformed hole 3 for blind hole and is extended to precasting portion 2 by fixed part 1, reserved
The length in 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 the 6 of preformed hole 3～8mm, can arrange according to the diameter of anti-tooth extractor.
Preferably, the 2/3 of a length of precasting pin body length of preformed hole 3, and be 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 revolve with spanner
Turn anti-tooth extractor, thus rotate the precasting pin staying these internal remnants of core rod.
Examples detailed above, only for technology design and the feature of the explanation present invention, its object is to allow the person skilled in the art be
Will appreciate that present disclosure and implement according to this, can not limit the scope of the invention with this.All according to present invention essence
God's equivalent transformation of being done of essence or modification, all should contain within protection scope of the present invention.
