Description
Technical field
The present invention relates to low pressure casting field, more particularly to a kind of metal aluminium ring low pressure casting running gate system.
Background technology
Low pressure casting is that molten metal is pressed into casting mold, and a kind of casting of crystallization and freezing under a certain pressure using gas pressure
Method is made, it is, steady to rise due to molten metal from bottom to top, splashing will not be produced when filling type, atmosphere, pressure adjustable do not need rising head
Feeding, casting quality are good, and product yield is high, is particularly well-suited to the light-alloys such as aluminum, magnesium.
As depicted in figs. 1 and 2, including aluminium ring body 1, the inwall of the aluminium ring body 1 is uniform in a ring for metallic aluminium ring structure
If dry hole is distributed with, wherein a hole is through hole 2, remaining hole is blind hole 3；At present when above-mentioned metal aluminium ring is made, using a mould
One mould structure for going out, as shown in figure 3, including cast gate 4, the product die cavity 5 of formation product, using lacking during the mould product
Point analysiss are as follows：
（1）Above-mentioned mould can produce waste material 6, and the material computing formula wasted by the waste material 6 is as follows：=+
=+（1）
Open height is poured wherein=30mm、=80mm, waste material height=30mm, waste material radius =
80mm,, substitute into formula（1）It is calculated=14.334kg, calculates it can be seen that the mould is used
Material is more, and the waste material for producing is more, the production cost of increase；
（2）From the low production efficiency that casting efficiency, a mould one go out；
（3）It is analyzed in terms of heat treatment, a mould one goes out when heat treatment is carried out, waste part equally will also carry out heat
Process, waste substantial amounts of heat energy, simultaneously because excess calories concentrate on waste of materials part, easily produce thermal deformation；So as to give
Machining brings processing difficulties；
（4）It is compared in terms of machining, a mould one goes out to need to cut down waste of materials part, needs to waste big
That what is measured is artificial, and Stress Release can cause aluminum circle to deform while cutting, and defective work increases.
The content of the invention
The technical problem to be solved in the present invention be to provide it is a kind of can improve production efficiency, cost-effective and gain reduce discharging
Metal aluminium ring low pressure casting running gate system.
To solve above-mentioned technical problem, the technical scheme is that：A kind of metal aluminium ring low pressure casting running gate system,
The running gate system of the casting mold includes sprue, cross gate and Inner cast gates, and its innovative point is：The die cavity of the casting mold is by a bottom
Seat, matched moulds the metal outer mold installed in base upper surface, the core being built in a pair of metal outer molds and before and after a pair
Die cap matched moulds of the matched moulds respectively a pair of metal outer mold upper surfaces is formed, the inner side before and after the pair of metal outer mold after matched moulds
Wall cooperatively forms some casting mold die cavities being axially sequentially distributed along core lateral wall with the lateral wall of core, each casting mold die cavity institute
There is an annular groove, on the lateral wall of the core of each casting mold die cavity region on the medial wall of the metal adventitia in region
Some convex bodys are evenly distributed with a ring；The sprue has a pair, is symmetricly set on the left and right sides of a pair of metal outer molds, institute
State each annular die cavity both sides corresponding with sprue and be provided with Inner cast gates, be provided with the base a pair respectively with a pair
The cast gate of sprue bottom connection, the bottom of the sprue connected with the stalk of low pressure casting by cast gate, at the top of which according to
It is secondary to be connected with the Inner cast gates of each casting mold die cavity by some cross gates；The center of the die cap is provided with an air vent.
Further, the core has an annular convex, the core bottom at base upper surface center in cylinder-shaped
Just it is supported in base annular convex.
Further, the core bottom has a detent, in annular convex has a corresponding positioning convex body.
Further, the casting mold die cavity has four, the sprue ovalize, and which is highly 375mm, major axis
110mm, short axle are 80mm, and the cross gate is rounded, its length 30mm, diameter 46mm.
It is an advantage of the current invention that：
（1）Running gate system of the present invention, the medial wall before and after a pair of metal outer molds after matched moulds coordinate shape with the lateral wall of core
Into some casting mold die cavities being axially sequentially distributed along core lateral wall, a modulus goes out；
From the point of view of production efficiency, several aluminium rings can be once produced, the production efficiency of product is improve；
It is analyzed in terms of heat treatment, a traditional mould one goes out product, carries out heat treatment, and waste of materials part is equally
Heat treatment to be carried out, wastes substantial amounts of heat energy, simultaneously because excess calories concentrate on waste of materials part, easily produces hot shape
Become, so as to bring processing difficulties to machining；And this one modulus of name goes out that aluminium ring is cleaved before heat treatment to be finished, as long as
Put smooth during heat treatment, thermal deformation would not occur；
It is compared in terms of machining, a traditional mould one goes out, needs to cut down waste of materials part, needs to waste
It is substantial amounts of artificial, and while cutting, Stress Release can cause aluminum circle to deform, and defective work increases；The product gone out using a modulus
Product, the danger for not having Stress Release only normally need to be machined, and process time greatly shortens, and production efficiency is substantially better than biography
Unified mould one goes out product；
（2）Core of the present invention has an annular convex at base upper surface center in cylinder-shaped, and core bottom just supports
In base annular convex so that core is firm to be supported on base, and cylinder-shaped structure reduces the cost of manufacture of core；
（3）Core bottom of the present invention has a detent, has a corresponding positioning convex body, be easy in annular convex
The location and installation of core；
（4）Waste material in running gate system of the present invention includes being produced in a pair of sprues and four casting mold die cavity both sides cross gates
Raw waste material, its computing formula are as follows：=*2+ *8
=+
*8（2）
Wherein sprue height=375mm, semi-major axis=55mm, semi-minor axis40mm,
Cross gate height=30mm, cross gate radius=23mm,, substitute into formula
（2）It is calculated=15.075kg；And the material weight wasted by four traditional casting molds is 14.334*4=57.2 kg, by
Calculate as can be seen that the running gate system materials of the present invention are few, and the waste material for producing is few, the production cost of saving, gain are reduced discharging.
