Abstract
The present invention provides a kind of sand mould structure of bearing cap, including sand mold ontology, it is tilting on the sand mold ontology to arrange four casting cavities two-by-two, each casting cavity is connect with a riser and ingate, the riser is connected using top pouring type, all ingates are connected with sprue, and the sprue is connect with sprue cup.There are one riser 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 connect with 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 bearing cap internal porosity, raising product yield, reduction
Rejection rate, the sand mould structure for improving production efficiency.
Background technology
Bearing cap product is the product of a hardware and software platform, and demand is especially huge, in increasingly fierce Market Competition
Under, manufacturing enterprise is faced with the pressure of the useless synergy of huge drop.
The similar product of traditional handicraft casting at present, using horizontal positioned technique, yield rate is 40% or so, rejection rate
7% or so, while easily there is shrinkage porosite in cast-internal, often complains by client, while also results in company's productive labor cost
Significant wastage.
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 bearing
The sand mould structure of lid using tilting arrangement technique, and combines bottom filling technique, not only meets internal porosity requirement, improve
Product yield 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 bearing cap, including sand mold
Ontology, which is characterized in that there are four the casting cavities of tilting arrangement, each casting cavity on the sand mold ontology to emit with top
Mouthful and ingate connection, the riser connected using top pouring type, all ingates connect with sprue, the sprue and
Sprue cup connects.Preferably, casting cavity tilting arrangement two-by-two, the riser are connected by riser neck structure with casting cavity.
Further, the modulus of the riser neck structure is 6mm.
Preferably, the cavity is directly connected to ingate, and ingate flow is 110mm2。
Preferably, the sprue flow being connect with ingate is 800mm2。
By above technical scheme, the present invention has following technique effect compared to the prior art：
Sand mould structure provided by the invention tilting arrangement two-by-two, there are one riser on each sand mold ontology, can to the greatest extent may be used
Meet the internal porosity of casting, while also improve product yield under the premise of riser that can be few；Cavity directly connects with ingate
It connects, reduces sand washing risk, 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, riser, 4, sprue cup, 5, sprue, 6, ingate.
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, the structure diagram of the sand mould structure preferred embodiment of bearing cap of the present invention is shown as, including sand
Type ontology 1, there are four casting cavities 2, four ingates 4 to be separately positioned on four casting cavities 2 for tilting arrangement on sand mold ontology 1
Side.The top of each casting cavity 2 is respectively communicated with a riser 3, according to the choked flow sectional area that each ingate 4 is calculated
For：F=110mm2.Ingate 4 is connected with corresponding sprue 5, is according to the choked flow sectional area for being calculated sprue 5：F=
800mm2.5 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
310cm3, feeder modulus is 12mm (modulus=volume/surface area).The modulus of riser neck structure is 6mm, can meet casting
The requirement of internal porosity, while improve product yield.
Using sand mould structure provided by the invention, during make-up a bearing lid casting can 4 casting of one-pass molding, since riser is set
Meter is reasonable, and internal soundness (shrinkage porosite situation) is satisfied；The product yield of product will be increased to 52% from original 40%,
Rejection rate is reduced to 3% by 7%；It greatly increases the production efficiency, reduces production cost.
In conclusion sand mould structure provided by the invention, four tilting arrangements of casting cavity, have on each sand mold ontology
One riser can meet the internal porosity requirement of casting under the premise of riser as few as possible；Casting cavity and ingate are direct
Connection reduces sand washing risk, rate of reducing the number of rejects and seconds；So the present invention effectively overcomes original technologic insufficient and has height and produce
Industry utility value.
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.
