Abstract
A kind of connection repetition riser and precoated sand cast gate retainer ring, characterized in that including the lower part of cylinder be provided with click-on mechanism;The click-on mechanism, including clamp is provided on claw;It is provided with gap between the adjacent claw;It is provided with camber on the claw;The bending direction of the adjacent claw is opposite;The claw quantity is arranged to even number;For connecting repetition riser and flush type precoated sand cast gate, the claw for being more than the multiple of slot width and tool elasticity using the adjacent claw bending spacing of its setting carries out plug-in type clamping with the slot in complexity precoated sand cast gate, the dead head that composition one and half repeats, reduce to most degree the volume of used complexity precoated sand dead head, remain with the riser that can be reused of pre-add hot function, product yield is improved, production cost is reduced.
Description
Technical field
This application involves aluminium alloy casting field, specifically a kind of connection repetition riser and precoated sand cast gate card
Circle.
Background technology
It is in growth momentum for energy-saving and emission-reduction, automotive light weight technology, wherein the aluminium produced with metal mold gravity casting mode closes
The share that golden part product occupies is larger, but production method traditional so far all is used to place on metal mold cast gate and disposably be covered
Film sand dead head is cast, and a product one cannot be reused, and make, using this precoated sand dead head not only
Pollution is big, and equipment and energy consumption, the waste of manpower are also more, of high cost;Although I has developed and trial operation can reuse
Dead head achieves the advantage that high degree of automation, product yield are high, energy saving, production cost is low, but for nonplanar complexity
The product of shape flush type pouring gate structure can not still use.
Invention content
The application is in view of the above-mentioned problems, provide a kind of connection repetition riser and precoated sand cast gate retainer ring, for connecting
Repetition riser and flush type precoated sand cast gate, are converted into disposable flush type precoated sand by disposable precoated sand dead head and pour
Mouthful, its volume is reduced to most degree, remains with the riser that can be reused of pre-add hot function, improves product yield, reduces life
Produce cost.
Technical solution according to the invention:A kind of connection repetition riser and precoated sand cast gate retainer ring, characterized in that packet
The lower part of the cylinder (1) included is provided with click-on mechanism;
Clamp (3) is provided in the click-on mechanism, including claw (2);
It is provided with gap between the adjacent claw (2);
It is provided with camber on the claw (2);
The bending direction of the adjacent claw is opposite;
Claw (2) quantity is arranged to even number;Ensure the concentricity after its connection;
Each apical position of the clamp (3) is in cylinder (1) on same vertical plane;
The diameter of the cylinder (1) is according to the card slot diameter setting in precoated sand cast gate;
The retainer ring is made of heat resisting steel steel band;
The claw of the retainer ring neither damages card slot after being inserted into precoated sand cast gate card slot, and can make precoated sand cast gate merging gold
Belong in mould cast gate, can be pulled away after casting indeformable after precoated sand cast gate and subject to capable of reusing;
Such as method one, the precoated sand cast gate of 60mm, 3 ± 0.1mm of slot width, deep 8-10mm weight are arrived for diameter 30
Precoated sand cast gate in 200 grams is made, the wide 3mm of claw, claw long 8- only of the heat resisting steel steel band of 0.10+0.1mm thickness
10mm, the bending spacing 4.2+0.5mm of adjacent claw;
The application's has technical effect that:A kind of connection repetition riser and precoated sand cast gate retainer ring, using its setting
The adjacent claw bending spacing claw that is more than slot width multiple and tool elasticity and the slot in complexity precoated sand cast gate
Plug-in type clamping is carried out, the dead head that composition one and half repeats scientifically solves on-plane surface complex shape flush type gate nub
Structure product can not use existing the problem of capable of repeating with dead head, farthest reduce used disposable precoated sand dead head
Volume, reduce a property precoated sand dead head pollution and energy consumption, make full use of pre-add hot function can reuse emit
Mouthful ensure that it makes the service life of reuse with retainer ring made of heat resisting steel steel band, improve product quality and yield, reduction product at
This.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of connection repetition riser and precoated sand cast gate retainer ring of the application.
Specific implementation mode
The specific implementation mode in the application is described further below in conjunction with the accompanying drawings.
In figure, including cylinder (1), claw (2), clamp (3) etc..
As shown in the figure, the application is that a kind of connection repeats riser and precoated sand cast gate retainer ring;
The retainer ring includes cylinder (1), claw (2), clamp (3);The clamp is set to claw lower end, the claw setting
In cylinder lower part;
It is provided with gap between the adjacent claw (2);
It is provided with camber on the claw (2);
The bending direction of the adjacent claw is opposite;
Claw (2) quantity is arranged to even number;
Each apical position of the clamp (3) is in cylinder (1) on same vertical plane;
The diameter of the cylinder (1) is according to the card slot diameter setting in precoated sand cast gate;
The retainer ring is made of heat resisting steel steel band;
The width of its claw is cut into length shapes using line;
The camber method one of the claw is suppressed using the shaper of design;Method two is using integer after manual bending;
The claw of the retainer ring neither damages card slot after being inserted into precoated sand cast gate card slot, and can make precoated sand cast gate merging gold
Belong in mould cast gate, can be pulled away after casting indeformable after precoated sand cast gate and subject to capable of reusing;
Such as method one, the precoated sand cast gate of 60mm, 3 ± 0.1mm of slot width, deep 8-10mm weight are arrived for diameter 30
Precoated sand cast gate in 200 grams is made, the wide 3mm of claw, claw long 8- only of the heat resisting steel steel band of 0.10+0.1mm thickness
