Abstract
The invention discloses a copper-aluminum alloy bottom pouring type pouring system structure. The structure comprises a plurality of runners of which the bottom parts are mutually communicated, wherein sprues are formed on the upper parts of the runners; the upper ends of the runners are mutually communicated and are communicated with risers; liquid inlet channels are formed beside the runners; the bottom parts of the liquid inlet channels are mutually communicated with the bottom parts of the runners; and the upper ports of the liquid inlet channels are basically flush with the upper ends of the runners. The liquid inlet channels are formed beside the plurality of runners of which the bottom parts are mutually communicated, copper-aluminum alloy melt overflows from the bottom parts of the runners through the liquid inlet channels, AL2O3 included slag in the runners is suspended on the upper surface to form a protective layer, pouring gas overflows from the risers above through the runners, the sprues are opened, and the copper-aluminum alloy melt is poured into a mold in the form of laminar flow, so that back flow and vortexes caused by direct pouring are avoided, and the moire and flow lines of parts can be effectively reduced.
Description
Technical field
The invention belongs to alloy placingJi Shu field, specifically relate to a kind of bottom gating structure of aluminium copper.
Background technology
Aluminium copper is the new copper alloy that RECENT DEVELOPMENTS is got up, and as a kind of industrial conventional tin-free bronze, its intensity, plasticity, chemical stability and compactness are all better than time-honored tin bronze, and cost is also much lower compared with tin bronze.But aluminium copper aluminium in the time of melting is very easily oxidized and forms AL2O3 suspension slag inclusion, in casting process, also easily form AL2O3 suspension slag inclusion, in addition aluminium copper vapour pressure in the time of melting is all lower than brass and tin bronze, air-breathing tendency is large, aluminium in molten state alloy be easy to smelting furnace in moisture react, the hydrogen producing is inhaled in aluminium copper, produces gas hole defect while causing pouring into a mould rear casting solidification moulding.Referring to Fig. 1, existing injection system structure is all upper formula, and watering cup is same parts with rising head, relies on gas to float to discharge cast gas in watering liquid.This injection system structure is unsuitable for the cast of aluminium copper, and the one, AL2O3 suspension slag inclusion easily stops up running channel, and the 2nd, exhaust does not freely easily cause product air holes defect.
Summary of the invention
The present invention solves the existing technical problem of above-mentioned prior art, and a kind of bottom gating structure of aluminium copper is provided.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of bottom gating structure of aluminium copper, comprise the running channel that some bottoms are interconnected, running channel top is provided with cast gate, and the upper end of described running channel is also interconnected, and is communicated to rising head; Described running channel is other is provided with liquid inlet channel, and the bottom of liquid inlet channel and the bottom of running channel are interconnected, and remains basically stable in the upper port of liquid inlet channel and the upper end of running channel.
As preferably, described liquid inlet channel is provided with screen pack, and screen pack is used for filtering trash, AL2O3 suspension slag inclusion etc., further to purify aluminium copper liquation.
As preferably, the top of described liquid inlet channel is communicated to running channel via short tube, and short tube is inclined upwardly, and the junction of short tube and liquid inlet channel be arranged on screen pack above, in liquid inlet channel, the part of floating cast gas enters running channel through short tube and emits through rising head.
As preferably, outside going out to be provided with, the upper port of described liquid inlet channel waters cup.
As preferably, under the cast gate on described running channel top is oblique, be connected to casting mold.
The other liquid inlet channel that is provided with of running channel that the present invention is interconnected in some bottoms; aluminium copper liquation is entered from running channel bottom overflow through liquid inlet channel; AL2O3 slag inclusion in running channel is suspended in upper surface; form protective layer; cast gas overflows from rising head above through each running channel; open cast gate aluminium copper liquation and be laminar-flow type injection mould, backflow and the whirlpool of having avoided direct-filling type to cause, can effectively reduce the folded line of part and flow liner.The present invention has the features such as simple in structure, reasonable in design.
Brief description of the drawings
Fig. 1 is a kind of structural representation of running gate system in prior art;
Fig. 2 is a kind of structural representation of the present invention;
Fig. 3 is a kind of structural representation in cross section of the present invention.
Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, technical scheme of the present invention is described in further detail.
Embodiment: referring to Fig. 2 and Fig. 3, in the present invention, some running channels 1 bottom is interconnected, and the upper end of running channel 1 is also interconnected, and is communicated to rising head 6; The top of each running channel 1 is provided with cast gate 4, under cast gate 4 is oblique, is connected to casting mold 5; The other liquid inlet channel 9 that is provided with of running channel 1, the upper port of liquid inlet channel 9 goes out to be provided with the outer cup 2 that waters, the bottom of the bottom of liquid inlet channel 9 and running channel 1 is interconnected, remain basically stable in the upper end of the upper port of liquid inlet channel 9 and running channel 1, liquid inlet channel 9 is provided with screen pack 8, screen pack 8 is used for filtering trash, AL2O3 suspension slag inclusion etc., further to purify aluminium copper liquation.The top of liquid inlet channel 9 is communicated to running channel 1 via short tube 7, and short tube 7 is inclined upwardly, and short tube 7 and the junction of liquid inlet channel 9 be arranged on screen pack 8 above, the part cast gas of liquid inlet channel 9 interior floatings enters running channel 1 through short tube 7 and emits through rising head 6.
The other liquid inlet channel that is provided with of running channel that the present invention is interconnected in some bottoms; aluminium copper liquation is entered from running channel bottom overflow through liquid inlet channel; AL2O3 slag inclusion in running channel is suspended in upper surface; form protective layer; cast gas overflows from rising head above through each running channel; open cast gate aluminium copper liquation and be laminar-flow type injection mould, backflow and the whirlpool of having avoided direct-filling type to cause, can effectively reduce the folded line of part and flow liner.
Finally, it should be pointed out that above embodiment is only the more representational example of the present invention.Obviously, the invention is not restricted to above-described embodiment, can also have many distortion.Any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment, all should think and belong to protection scope of the present invention.
