Description
Technical field
The present invention relates to low pressure casting field, particularly a kind of metallic aluminium ring low pressure casting running gate system.
Background technology
Low pressure casting utilizes gas pressure that molten metal is pressed into casting mold, and a kind of casting method of crystallization and freezing under a certain pressure, due to molten metal from bottom to top, steady rising, can not produce splashing when filling type, atmosphere, pressure adjustable, do not need riser feeding, casting quality is good, and product yield is high, is specially adapted to the light-alloy such as aluminium, magnesium.
Metallic aluminium ring structure as depicted in figs. 1 and 2, comprises aluminium ring body 1, and the inwall of this aluminium ring body 1 is evenly distributed with some holes ringwise, and wherein a hole is through hole 2, and all the other holes are blind hole 3; At present when making above-mentioned metallic aluminium ring, adopting the mould structure that a mould one goes out, as shown in Figure 3, comprising cast gate 4, forming the product die cavity 5 of product, adopting weaknesses analysis during this mould product as follows:
(1) above-mentioned mould can produce waste material 6, and the material computing formula that this waste material 6 is wasted is as follows: QUOTE

(4) compare from machined aspect, a mould one goes out to need to be cut down by waste material component, need to waste a large amount of artificial, and while cutting, Stress Release can cause aluminium circle to be out of shape, defective work increase.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind ofly can to enhance productivity, metallic aluminium ring low pressure casting running gate system that cost-saving and gain reduces discharging.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of metallic aluminium ring low pressure casting running gate system, the running gate system of described casting mold comprises sprue, cross gate and Inner cast gate, its innovative point is: the die cavity of described casting mold is by a base, matched moulds before and after a pair is also arranged on the metal outer mold of base upper surface, be built in core in pair of metal external mold and a pair respectively matched moulds form at the die cap matched moulds of pair of metal external mold upper surface, madial wall before and after described pair of metal external mold after matched moulds coordinates with the lateral wall of core and forms some casting mold die cavities axially distributed successively along core lateral wall, the madial wall of the metal adventitia of each casting mold die cavity region has an annular groove, the lateral wall of the core of each casting mold die cavity region is evenly distributed with some convex bodys ringwise, described sprue has a pair, be symmetricly set on the left and right sides of pair of metal external mold, the both sides that described each annular die cavity is corresponding with sprue are provided with Inner cast gate, described base is provided with a pair respectively with the cast gate be communicated with bottom a pair sprue, the bottom of described sprue is communicated with the stalk of low pressure casting by cast gate, and its top is communicated with the Inner cast gate of each casting mold die cavity by some cross gates successively, the center of described die cap has an exhaust outlet.
Further, described core is cylinder-shaped, has an annular convex, be just supported in base annular convex bottom described core at center, base upper surface.
Further, there is bottom described core a detent, there is the positioning convex body of a correspondence in annular convex.
Further, described casting mold die cavity has four, described sprue ovalize, and it is highly 375mm, major axis 110mm, minor axis is 80mm, and described cross gate is rounded, its length 30mm, diameter 46mm.
The invention has the advantages that:
(1) running gate system of the present invention, the madial wall before and after pair of metal external mold after matched moulds coordinates with the lateral wall of core and forms some casting mold die cavities axially distributed successively along core lateral wall, and a modulus goes out;
From production efficiency, once can produce several aluminium rings, improve the production efficiency of product;
Analyze from heat treatment aspect, a traditional mould one goes out product, heat-treats, waste material component equally also will be heat-treated, and wastes a large amount of heat energy, simultaneously because excess calories concentrates on waste material component, easy generation thermal deformation, thus bring processing difficulties to machined; And this name one modulus goes out aluminium ring has cut complete before heat treatment, as long as put smooth when heat treatment, thermal deformation would not be there is;
Compare from machined aspect, a traditional mould one goes out, and needs waste material component to cut down, and need to waste a large amount of artificial, and while cutting, Stress Release can cause aluminium circle be out of shape, defective work increase; The product adopting a modulus to go out, does not have the danger of Stress Release, and only need normal machined, process time shortens greatly, and production efficiency is obviously better than a traditional mould one and goes out product;
(2) core of the present invention is cylinder-shaped, has an annular convex, be just supported in base annular convex bottom core at center, base upper surface, make firm being supported on base of core, and cylinder-shaped structure decreases the cost of manufacture of core;
(3) bottom core of the present invention, there is a detent, there is the positioning convex body of a correspondence in annular convex, be convenient to the location and installation of core;
(4) waste material in running gate system of the present invention comprises the waste material produced in a pair sprue and four casting mold die cavity both sides cross gates, and its computing formula is as follows: QUOTE
