Abstract
The utility model relates to a stalk for cast aluminium alloy mainly is applied to among the cast aluminium alloy aluminium liquid and carries the field, including outer pipe, outer outside of tubes portion be cylindrical, and outer intraductal chamber is the taper shape that the upper end opening is big, conical inlayer pipe that outer intraductal suit and outer intraductal chamber suited, and the intraductal chamber of inlayer is the taper shape that the upper end opening is big. The utility model discloses the inner chamber is conical, and aluminium liquid is carried more smoothly, can satisfy the heat preservation demand, reduces the processing cost.
Description
Technical field
The utility model relates to a kind of Birmasil stalk, is mainly used in aluminium liquid transportation art in Birmasil.
Background technology
At present, low pressure casting all adopts ceramic lift tube and intervalve, cup, sprue bush composition to rise liquid passage, and be forced through by aluminium liquid and rise in liquid passage press-in die die cavity, existing stalk exists following defect:
(1) inner chamber mostly is cylindrical, flows smooth and easy not;
(2) existing stalk generally adopts aluminum silicate ceramic to make stalk, and aluminum silicate ceramic inwall easily corrodes, and after corrosion, alumina silicate residue is easily fallen in aluminium liquid and polluted aluminium liquid, and the aluminum silicate ceramic after corrosion needs often to change, and too increases production cost;
(3) existing stalk tube wall is thinner, can not be incubated aluminium liquid, if tube wall is too thick, processing cost is too high again.
Utility model content
The purpose of this utility model is to provide a kind of Birmasil stalk, and inner chamber is conical, and the conveying of aluminium liquid is more smooth and easy, can meet insulation demand, cut down finished cost.
Birmasil stalk described in the utility model, comprise outer tube, outer tube outside is cylindrical, and outer tube inner chamber is the taper shape that upper end open is large, the conical inner tube that in outer tube, suit and outer tube inner chamber adapt, inner tube inner chamber is the taper shape that upper end open is large.
Described Birmasil stalk, outer tube and inner tube are bonded by adhesive, and inner tube inner chamber upper end open is large, and lower ending opening is little, and by applying pressure, aluminium liquid is upwards carried from stalk lower end, carries more smooth and easy; Described Birmasil stalk lower end wall thickness, intensity is good, can be incubated, and described Birmasil stalk upper end wall is thin, can save cost.
Described outer tube inwall is provided with locating slot, corresponding locating slot, and inner tube outer wall is provided with positioning table; Locating slot arranges 2-5; Locating slot can arrange 2,3,4,5, corresponding locating slot, inner tube outer wall is arranged 2,3,4,5 positioning tables; Be convenient to inner tube and outer tube installation.
Described inner tube outer surface tapering is identical with inner cavity taper.Inner tube uniform wall thickness, is convenient to processing.
Described inner tube is titanium nitride ceramic inner tube; Titanium nitride ceramic inner tube is not perishable, and be not stained with aluminium liquid, service time is long, reduces production cost, does not pollute aluminium liquid.
Described outer tube is aluminum silicate ceramic outer tube; Aluminum silicate ceramic is lower than titanium nitride ceramic cost, therefore arranges the Birmasil stalk that titanium nitride ceramic inner tube and aluminum silicate ceramic outer tube combine, can be corrosion-resistant, and be not stained with aluminium liquid, service time is long, and do not pollute aluminium liquid, processing cost is low.
Filter is provided with bottom described outer tube and inner tube; Impurity in elimination aluminium liquid, improves the quality of products.
Described filter comprises filter screen, and filter screen periphery is provided with installation sleeve, and installation sleeve outward flange is provided with erecting bed, and erecting bed is positioned at outer tube bottom outside; Firmly easy for installation.
Compared with prior art, the beneficial effects of the utility model are:
(1) the utility model adopts inner tube and outer tube to combine, and inner chamber is set to taper shape, and the flowing of aluminium liquid is more smooth and easy;
(2) inner tube and outer tube correspondence arrange positioning table and locating slot, install more reliably easy;
(3) the Birmasil stalk adopting titanium nitride ceramic inner tube and aluminum silicate ceramic outer tube to combine, can be corrosion-resistant, and be not stained with aluminium liquid, service time is long, and do not pollute aluminium liquid, processing cost is low;
(4) by arranging filter bottom inner tube and outer tube, can impurity in elimination aluminium liquid, improve the quality of products.
