Description
Technical field
The utility model belongs to the Casting Equipment of machine industry, more particularly to a kind of large high-strength shell of resistance to die casting aluminium
The casting device of body.
Background technology
Aluminium alloy castings is widely used in aviation, boat because it has the characteristics that high intensity, density is small, good corrosion resistance
My god, the industry such as electric power, automobile, machinery.The overpressure resistant aluminum housing casting low pressure casting requirement technique of wherein high voltage power transmission and transforming is one
The precise forming technique that kind production efficiency is high, allowance is few, aluminium water use efficiency is high, air-tightness is high.During casting, using resin sand
Type gravitational casting, but product yield only has 50%, and cast(ing) surface Micro shrinkage is serious, and the disposable qualification rate of airtight test is low,
Casting equipment and condition are relatively unstable, influence product quality stability, and production efficiency is not high, and operation is cumbersome.
The content of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, there is provided one kind makes casting various functional, operation
Simply, the casting device of the resistance to die-cast aluminium shell of the high large high-strength of production efficiency.
The utility model solves the technical scheme that technical problem uses：The casting dress of the resistance to die-cast aluminium shell of large high-strength
Put including under casing, nowel, top box, spacer block, be characterized in, between under casing and nowel, between nowel and top box and top box
Spacer block is equipped with top, horizontal and both ends vertical direction is provided with main running channel in nowel, and lower section connects in the middle part of main running channel
Provided with aluminium liquid introducing port, chill is provided with the both ends of the surface of main running channel periphery, several cross gate is provided with being connected with main running channel, in horizontal stroke
Connection sprue above running channel both ends, it is horizontal in the top box above main running channel to be provided with arbor, core is provided with the periphery of arbor,
Casting die cavity is provided with the periphery of core, gap running channel is provided with the outside of casting die cavity, is set at the horizontal both ends of casting die cavity
There is chill, be provided with the both ends of casting die cavity and fill type node, the gap filling core sand under casing, nowel and top box.
The beneficial effects of the utility model are：The casting device of the resistance to die-cast aluminium shell of large high-strength makes each position of casting
Contraction can be supplemented, necking is transferred in rising head and running channel, obtain densification casting.It is especially less uniform to wall thickness
The casting of large high-strength is pressure-resistant aluminum hull is advantageously.Casting cycle Stable Filling, feeding aluminium water thermal loss is reduced, improve heat
The advantages of section position feeding validity and improvement temperature are uniformly distributed, can be achieved flexible, effective, prolonged pressure transmission.Solution
The casting that complexity of having determined is high, wall thickness change is big caused misrun, cold shut, shrinkage cavity and shrinkage porosite over long distances to feeding deficiency
The defects of the problem of.
