Abstract
The present invention provides a kind of sand mould structure of automobile brake pincers housing, including sand mold ontology, there are three casting cavities on the sand mold ontology, each casting cavity is connect with riser and ingate, the riser is connected using top pouring type, all ingates are connected with sprue, and the sprue is connect with cross gate, and the cross gate is connect with sprue cup.There are one top risers on each sand mold ontology for sand mould structure provided by the invention, and the internal porosity requirement of casting can be met under the premise of riser as few as possible, improves product yield；Cavity is directly connected to ingate, reduces sand washing risk, and rate of reducing the number of rejects and seconds improves production efficiency.
Description
Technical field
The present invention relates to casting fields；More particularly to a kind of optimization automobile brake pincers enclosure interior shrinkage porosite, raising technique go out
Product rate, rate of reducing the number of rejects and seconds, the sand mould structure for improving production efficiency.
Background technology
Caliper shell is the product of a hardware and software platform, can be applicable in more money vehicles, will put into batch production, simultaneously
The product is also being developed in foreign countries, and market competition is very fierce so that manufacturing enterprise is faced with stern challenge.
The similar product of traditional handicraft casting at present, using double riser techniques, yield rate is 40% or so, rejection rate 6%
Left and right, while cast-internal shrinkage porosite exceeds 100mm2, beyond Customer Standard requirement, 100% flaw detection is needed, not only often by visitor
Family is complained, while also results in the significant wastage of company's productive labor cost.
Invention content
In view of various deficiencies of prior art described above, the technical problem to be solved in the present invention is to provide a kind of automobile
The sand mould structure of caliper shell using top riser technique, and combines bottom filling technique, not only meets internal porosity requirement,
Product yield is improved, also reduces rejection rate, improves production efficiency.
In order to achieve the above objects and other related objects, the present invention provides a kind of sand mould structure of automobile brake pincers housing,
Including sand mold ontology, which is characterized in that there are three casting cavity, each casting cavity and top risers on the sand mold ontology
And ingate connection, the top riser are connected using top pouring type, all ingates are connected with sprue, and the sprue is equal
It is connect with cross gate, the cross gate is connect with sprue cup.Preferably, the riser passes through riser neck structure and casting cavity
Connection.
Further, the modulus of the riser neck structure is 3mm.
Preferably, the cavity is directly connected to ingate, and ingate flow is 190mm2。
Preferably, the sprue being connect with ingate, each sprue flow are 310mm2。
By above technical scheme, the present invention has following technique effect compared to the prior art：
Sand mould structure provided by the invention has 1 riser on each sand mold ontology, can be in riser premise as few as possible
It is lower to meet the internal porosity of casting, while also improve product yield；Cavity is directly connected to ingate, reduces sand washing wind
Danger, rate of reducing the number of rejects and seconds.
Description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is shown as the structure diagram of present pre-ferred embodiments.
1 in figure, sand mold ontology, 2, casting cavity, 3, top riser, 4, ingate, 5, sprue, 6, cross gate, 7, cast gate
Cup.
Specific embodiment
Embodiments of the present invention are illustrated by particular specific embodiment below, those skilled in the art can be by this explanation
Content disclosed by book understands other advantages and effect of the present invention easily.
Structure, ratio, size depicted in this specification institute accompanying drawings etc., only to coordinate specification it is revealed in
Hold, so that those skilled in the art understands and reads, be not limited to the enforceable qualifications of the present invention, therefore do not have skill
Essential meaning in art, the modification of any structure, the change of proportionate relationship or the adjustment of size can be produced not influencing the present invention
Under the effect of raw and the purpose that can reach, should all still it fall in the range of disclosed technology contents are obtained and can be covered.
Meanwhile cited such as " on ", " under " in this specification, "left", "right", " centre " and " one " term, be merely convenient to
Narration understand rather than to limit the enforceable range of the present invention, relativeness is altered or modified, without substantive change
Under technology contents, when being also considered as the enforceable scope of the present invention.
As shown in fig.1, it is shown as the structural representation of the sand mould structure preferred embodiment of automobile brake pincers housing of the present invention
Figure including sand mold ontology 1, is arranged on sand mold ontology 1 there are three casting cavity 2, four ingates 4 to be separately positioned on three casting
2 side of cavity.The top of each casting cavity 2 is respectively communicated with a top riser 3, according to the resistance that each ingate 4 is calculated
Flow section accumulates：F=190mm2.Ingate 4 is connected with corresponding sprue 5, according to the choked flow section that sprue 5 is calculated
Product is：F=310mm2.5 sprue cup 6 of sprue connects.
As a further improvement on the present invention, riser 3 is by riser neck structure and cavity unicom, the volume of riser
386cm3, feeder modulus is 10.5mm (modulus=volume/surface area).The modulus of riser neck structure is 3mm, can meet casting
Internal porosity requirement, while improve product yield.
Using sand mould structure provided by the invention, when pouring into a mould caliper shell casting can three casting of one-pass molding, due to
Feeder Design is reasonable, and internal soundness (shrinkage porosite situation) is satisfied；The product yield of product will be improved from original 40%
To 46%, rejection rate is reduced to 2% by 6%；It greatly increases the production efficiency, reduces production cost.
In conclusion sand mould structure provided by the invention has 1 riser on each sand mold ontology, it can be as few as possible
Meet the internal porosity requirement of casting under the premise of riser；Casting cavity is directly connected to ingate, reduces sand washing risk, is reduced useless
Product rate；So the present invention effectively overcomes original technologic insufficient and has high industrial utilization.
The above-described embodiments merely illustrate the principles and effects of the present invention, and is not intended to limit the present invention.It is any ripe
The personage for knowing this technology all can carry out modifications and changes under the spirit and scope without prejudice to the present invention to above-described embodiment.Cause
This, those of ordinary skill in the art is complete without departing from disclosed spirit and institute under technological thought such as
Into all equivalent modifications or change, should by the present invention claim be covered.
