Description
Technical field
The utility model relates to aluminium alloy casting technology field, relates in particular to a kind of dead head structure of aluminium alloy water inlet pipe.
Background technology
Usually the structure of the water inlet pipe of automobile engine as shown in Figure 1, comprise body 1 and be arranged at main rising head 2 and the blind riser 3 on described body 1, described body 1 one end is water inlet 4, described water inlet 4 is provided with described main rising head 2, described body 1 is provided with gas outlet 5, described gas outlet 5 is provided with described blind riser 3, and described blind riser 3 communicates with the tube chamber of described body 1 by conducting portion 6.What adopt is the permanent mold casting of 90 ° of quiescent pouring machines, and body 1 is aluminum alloy material, and described water inlet pipe internal structure is by core moulding, and described core is processed through cold core process.
We know, due to structure and casting parameter, in die cavity, the molten steel solidification time of the molten condition of each point is unequal, and this produce thermal stress will to foundry goods after solidifying, and causes casting deformation, crackle etc.Meanwhile, due to the cooled and solidified time not etc., the defect such as that foundry goods there will be is loose, cold shut, pore.Thin, the described main rising head 2 of described water inlet pipe integral wall of the prior art is thick large, during cast, aluminum liquid filling type condition is poor, therefore at described main rising head 2 places of described water inlet pipe, easily there is thermal center, and do not have effective measures to thermal center carry out feeding, and then cause shrinkage porosite.The shrinkage porosite percent defective that we know described water inlet pipe by production practices, up to 15%, has improved production input cost, has also caused the waste of resource simultaneously.
Utility model content
Technical problem to be solved in the utility model is: prior art does not have effective measures to carry out feeding to the thermal center at the main rising head place of water inflow of the engine pipe.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of dead head structure of aluminium alloy water inlet pipe, comprise body and be arranged at main rising head and the blind riser on described body, described body one end is water inlet, described water inlet is provided with described main rising head, described body is provided with gas outlet, described gas outlet is provided with described blind riser, described blind riser communicates with the tube chamber of described body by conducting portion, between described main rising head and described blind riser, by Feeding channel, connect, described Feeding channel connects described main rising head and described blind riser by groove, the cross-sectional area of described groove and the cross-sectional area of described blind riser match.
Preferably the tube chamber of described body adopts the core casting that cold-box process is prepared from.
Preferably described core is wick sand, closes a kind of in fat core sand or resin core sand.
Preferably described blind riser is atmospheric feeder.
Preferably described main rising head is spherical feeder.
Adopt technique scheme, the utility model at least comprises following beneficial effect:
The dead head structure of a kind of aluminium alloy water inlet pipe described in the utility model, adopts metal mold gravity casting, by tilting type pouring procedure, is prepared from, simple in structure, easily realizes and promotes.Improved the quality of cast blank, reduced the waste product of the water inlet pipe finished product causing because of described water inlet pipe shrinkage defect, described water inlet pipe percent defective is down to 3% left and right by 15.0% original left and right.Reduce the cost of processing, improved the quality of described water inlet pipe, reduced mass loss.
Accompanying drawing explanation

Fig. 2 is the dead head structure schematic diagram of aluminium alloy water inlet pipe described in the utility model.
Wherein: 1. body, 2. main rising head, 3. blind riser, 4. water inlet, 5. gas outlet, 6. conducting portion, 7. Feeding channel.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 2, for meeting the dead head structure of a kind of aluminium alloy water inlet pipe of the present utility model, comprise body 1 and be arranged at main rising head 2 and the blind riser 3 on described body 1, described body 1 one end is water inlet 4, described water inlet 4 is provided with described main rising head 2, described body 1 is provided with gas outlet 5, described gas outlet 5 is provided with described blind riser 3, described blind riser 3 communicates with the tube chamber of described body 1 by conducting portion 6, between described main rising head 2 and described blind riser 3, by Feeding channel 7, connect, described Feeding channel 7 connects described main rising head 2 and described blind riser 3 by groove, the cross-sectional area of the cross-sectional area of described groove and described blind riser 3 matches.
The dead head structure of a kind of aluminium alloy water inlet pipe described in the present embodiment adopts metal mold gravity casting, by tilting type pouring procedure, be prepared from, at the beginning of preparation, by the metal pattern structure to Birmasil water inlet pipe, change, by machine away a groove at metal pattern opposite position, described groove size is corresponding with described blind riser 3 sizes.Thereby can obtain the dead head structure of the aluminium alloy water inlet pipe described in the present embodiment not, from described main rising head 2, open a Feeding channel 7, aluminium water can direct compensation thermal state metal, solves shrinkage porosite problem herein, the rate of reducing the number of rejects and seconds.Water inlet pipe structure described in employing the present embodiment, its percent defective is down to 3% left and right by 15.0% original left and right.The concrete shape of described body 1 and structure can be set according to actual user demand, and the present embodiment is not construed as limiting this.Due to the concrete shape of described body 1 and those skilled in the art's routine techniques means that are set as of structure, so locate to repeat no more.
