Abstract
The utility model discloses a die-casting die for manufacturing a lower fastening head. A filling cavity is arranged in the die according to the shape of the lower fastening head, a feeding port, an exhaust slag discharging channel, a core pulling opening and a pouring gate are formed in the die, and the pouring gate is of an arc structure. The die-casting die has the advantage that the pouring gate is arranged to be a space curve channel, namely the arc structure, according to the characteristics of HD4 aluminum alloy materials of poor mobility, so that liquid aluminum alloy can smoothly flow into the die cavity along the pouring gate, and the filling performance is good.
Description
Technical field
The utility model designs the die cast mould, relates in particular to the die casting of discount under the strong manufacturing aluminium alloy of a kind of flowability.
Background technology
In aluminum alloy die casting, along with automobile, the light-weighted requirement of motorcycle, must guarantee that the part of intensity is more and more many, so the intensity of aluminum alloy die casting and material have become an important topic of industry to the influence of quality.In order to realize lightweight, matter of utmost importance is to adopt high-strength material to substitute common material.Yet high-intensity material often adopts magnesium elements to add, and causes its difficult moulding in the processing press casting procedure.The product that this patent is produced is to adopt the HD4 high strength die-casting aluminum alloy, be celebrated with high tenacity, high-elongation, high-tensile, but since the high easily scaling loss of HD4 aluminum alloy materials magnesium content, mobile poor, difficult moulding, difficulty process etc.The exploitation manufacturing of this die casting just had to meet the corresponding requirement of its product performance.
Following discount is for being used for the fixedly snap part of motorcycle handle, be divided into discount and following discount, wherein descend the die casting of discount the most difficult, when particularly using the HD4 aluminum alloy materials to pour into a mould, the high easily scaling loss of HD4 aluminum alloy materials magnesium content, mobile poor, difficult moulding, difficult processing on the one hand, the running channel of mould is generally linear pattern on the other hand, this will bring two shortcomings, one HD4 aluminum alloy materials is mobile poor, the HD4 aluminum alloy materials directly washes away the mould mandrel on the other hand, easily the mould mandrel is caused wearing and tearing.
The utility model content
The purpose of this utility model is in order to overcome above-mentioned the deficiencies in the prior art, a kind of die casting of making down discount good fluidity, easy-formation, easy processing to be provided.
To achieve these goals, the scheme of the utility model employing is:
A kind of die casting of making down discount offers according to the shape design of discount down in the mould and fills the chamber, has charging aperture, exhaust slagging channel on the mould, looses core mouthful and running channel, and described running channel is arcuate structure.
In order to make product good at cast gate place exterior quality after processing, the utility model is further optimized, and the described mouth of loosing core is opened in intrados one side of running channel.
In order to guarantee that metal flow is smooth and easy in the mold cavity, make the inner pore-free of product, improved product quality.The utility model is further optimized, described exhaust slagging channel be two and more than, be separately positioned on the two side of mould.
In order effectively to carry out exhaust, and can improve the molten metal state that flows, the utility model is further optimized, and described exhaust slagging channel is three.
The beneficial effects of the utility model are, at the characteristics of HD4 aluminum alloy materials poor mobile performance, the running channel of the utility model die casting product is a space curve passage, is arcuate structure, liquid aluminium alloy can flow in the mold cavity swimmingly along running channel, and filling capacity is good.
Description of drawings
Fig. 1 is the structural representation of the utility model die casting;
Wherein,
1: mould; 2: fill the chamber; 3: charging aperture; 4: the exhaust slagging channel; 5: running channel; 6: the mouth of loosing core.
The specific embodiment
By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.
See also Fig. 1, as shown in the figure, the utility model die casting is for the manufacture of the following discount of aluminum alloy material, the mould 1 interior basis shape design of discount down offers filling chamber 2, have the charging aperture 3 that enters for material on the mould 1, the exhaust slagging channel 4 that is used for the exhaust deslagging, loose core mouthfuls 6 and running channel 5, described exhaust slagging channel 4 is to be two or more, be separately positioned on the two side of mould 1, a side can be arranged on simultaneously and also both sides can be separately be arranged on, optimum mode exhaust slagging channel 4 is three, three exhaust slagging channels 4 can effectively carry out exhaust, and can improve the mobile state of molten metal, described running channel 5 is arcuate structure, at the characteristics of HD4 aluminum alloy materials poor mobile performance, the running channel 5 of the utility model die casting product is a space curve passage, is arcuate structure, liquid aluminium alloy is in running channel can flow into the filling chamber 2 of mould 1 swimmingly, and filling capacity is good.
In the present embodiment, the described mouth 6 of loosing core is opened in intrados one side of running channel 5, and namely running channel 5 is walked around the mouth 6 of loosing core, and makes product good at cast gate place exterior quality after processing.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
Claims (4)
